Is It Legal to Record a Conversation in Maryland?
Key facts
- ·Maryland requires all parties to consent before recording a conversation that qualifies as a protected "oral communication" (in-person talks) or a wire/electronic communication (phone calls, texts, emails), with limited exceptions.
- ·Public conversations where people have no reasonable expectation of privacy—such as loud speech on a public sidewalk—can be recorded without consent, but the analysis turns on the specific facts of each case.
- ·Recording police officers performing official duties in public is generally permitted without their consent under persuasive, non-binding authority, but the rule should be read narrowly to public roadside encounters.
- ·Phone calls, texts, and emails are automatically protected under the all-party consent rule, with no need to inquire whether the communication is "private."
- ·Video recordings without audio are not restricted by Maryland’s wiretap law, but if audio is captured, the all-party consent rule applies to that audio track.
- ·Violations can result in felony charges (up to five years imprisonment and a $10,000 fine) for illegal interception, plus civil lawsuits with damages of at least $100 per day or $1,000 per violation, plus attorney’s fees.
- ·Maryland’s 2024 Online Data Privacy Act treats biometric data, including voice prints, as "sensitive data" and prohibits its collection unless strictly necessary to provide a requested product or service; consent alone does not suffice.
Maryland’s all-party consent rule for private conversations
Maryland’s wiretap law makes it unlawful to intercept a communication without the consent required by statute. Under §10-402(a), it is a crime to intercept a wire, oral, or electronic communication unless an exception applies. The core exception for recording conversations is found in §10-402(c)(3), which provides that interception is lawful where the person recording is a party to the communication and all parties have given prior consent. This means that if you are part of a conversation—whether in person, by phone, or electronically—you must obtain consent from every other participant before recording. The statute does not create a blanket prohibition on interception; rather, it prohibits interception without the statutorily required consent. Maryland courts have applied this framework to both wire communications (such as phone calls) and in-person conversations that qualify as protected communications under the statute. The law treats wire and electronic communications as protected per se, while in-person conversations are protected only if they meet the reasonable-expectation-of-privacy test discussed below. Recording without the required consent can expose you to felony charges and civil liability.
What counts as a private conversation under Maryland law
Not every conversation is protected by Maryland’s wiretap law. A conversation is only protected if it qualifies as an "oral communication" under §10-401(13)(i), which defines an "oral communication" as any conversation or words spoken to or by any person in private conversation. Maryland courts apply a two-part reasonable-expectation-of-privacy (REOP) test—derived from the federal Katz standard—to determine whether a conversation is a protected "oral communication." The test asks: (1) did the speaker subjectively expect the conversation to be private, and (2) would society recognize that expectation as reasonable? For example, two people speaking loudly on a public sidewalk where others can easily overhear likely do not have a reasonable expectation of privacy, while two people whispering in a quiet corner of a restaurant probably do. The law does not provide a bright-line rule; the outcome turns on the specific facts of each case. Maryland courts have emphasized that even being in your own home does not guarantee privacy if the speaker’s volume or circumstances effectively expose the conversation to unintended listeners. In Malpas v. State, 116 Md. App. 69, 695 A.2d 588 (Md. Ct. Spec. App. 1997), Richard Craigie—a third-party witness in the underlying prosecution—shouted loudly in his own apartment, where his profane statements were audible through a shared wall to defendant Malpas in the adjoining unit; Malpas recorded Craigie using a handheld cassette recorder. The court held Craigie’s shouted statements were not a protected "oral communication" because the shouting was "the functional equivalent of statements knowingly exposed to the public." The court rejected the argument that being in one’s own home alone creates a reasonable expectation of privacy when the speech is loud enough to be overheard by others.
Recording police officers in public
You can generally record police officers performing their official duties in public without their consent, but this area of law remains fact-specific and is governed by persuasive, non-binding authority rather than a definitive appellate ruling. In State v. Graber, Harford Co. Cir. Ct., Crim. No. 12-K-10-000462 (Md. Cir. Ct. Sept. 27, 2010) (unreported), a trial court dismissed wiretap felony charges against a motorcyclist who used a helmet cam to record a plainclothes state trooper during a traffic stop on a public highway. The court held the trooper did not have a reasonable expectation of privacy in the conversation given the public nature of the stop. Maryland’s then-Attorney General reached the same conclusion in a 2010 opinion letter. However, this decision is not binding on other Maryland courts, and no published Maryland appellate decision has definitively ratified the holding. The Fourth Circuit, which includes Maryland, has recognized a First Amendment right to record or livestream police performing their duties in public in Sharpe v. Winterville Police Dep't, 59 F.4th 674 (4th Cir. 2023), though that case concerned qualified immunity rather than the existence of the right itself. Because State v. Graber is an unreported trial-court decision with no appellate ratification, its holding should be read narrowly to its own facts—a public roadside traffic stop—and not generalized to all police-present situations. If the encounter moves indoors, into a vehicle, or to a less clearly public setting, the analysis may change, and attorney review is recommended before treating the conversation as consent-exempt.
Phone calls, texts, and other electronic communications
Maryland’s all-party consent rule applies automatically to phone calls and electronic messages such as texts or emails, with no need to inquire whether the communication is "private." The statute defines "wire communication" in §10-401(18) as any communication made through a phone system and "electronic communication" in §10-401(5) to include texts, emails, and similar messages transmitted by electronic means. These categories are protected per se under §10-402, meaning the law protects them regardless of a case-by-case reasonable-expectation-of-privacy showing. You must obtain consent from all parties before recording a phone call or capturing an electronic message. The only statutory exception to the all-party consent rule is where the interception is made for the purpose of committing a criminal or tortious act, but that exception does not authorize recording without consent. Violations of the interception prohibition for wire or electronic communications can result in felony charges under §10-402(b), which carries a maximum penalty of five years imprisonment and a $10,000 fine.
Video-only recordings and silent surveillance
Maryland’s wiretap law restricts only the interception of audio communications. The statute’s prohibition applies to the interception of a "wire, oral, or electronic communication" as defined in §10-401, and all of these categories involve sound. A video recording made without capturing any audio therefore does not "intercept" any statutorily defined communication and falls outside the Act, regardless of consent. This interpretation follows directly from the statutory text and is the consistent view applied by Maryland practitioners and secondary sources. However, if your recording includes audio—even if captured accidentally—the all-party consent rule applies to that audio track. This means that if you are recording video of a conversation, you must ensure no audio is captured unless every person involved consents. The moment audio is captured alongside the video, the ordinary all-party-consent analysis under §10-402 applies to the audio component.
Penalties and legal risks for violations
Recording someone without the statutorily required consent in Maryland can lead to both criminal charges and civil lawsuits. Under §10-402(a) and (b), illegally intercepting a wire, oral, or electronic communication is a felony punishable by up to five years in prison and a $10,000 fine. The statute also provides for lesser penalties for related offenses, such as unlawful divulgence of intercepted communications, which may be charged as misdemeanors depending on the circumstances. Beyond criminal exposure, the person you recorded can bring a private civil action under §10-410, which authorizes damages of at least $100 per day of violation or $1,000 in liquidated damages (whichever is greater), plus punitive damages and reasonable attorney’s fees. These penalties apply even if you did not intend to break the law, and the law allows for civil suits even if no criminal charges are filed. Because the stakes are high—including potential felony liability—the safest practice is to obtain consent before recording any conversation unless you are confident the communication falls outside the wiretap statute’s protections.
Exceptions and nuances: when the all-party rule does not apply
Maryland’s all-party consent rule does not apply to every conversation or setting. For in-person conversations, the rule only applies if the conversation qualifies as a protected "oral communication" under §10-401(13)(i)—that is, a conversation made under circumstances justifying an expectation that it is not subject to interception. Conversations conducted in public, in a loud voice, or otherwise observable or audible to third parties generally fall outside the statute’s protection, meaning no all-party consent is legally required to record them. Loud speech in one’s own home can also forfeit protection, as illustrated by Malpas v. State, where Richard Craigie’s shouted statements in his apartment—audible through a shared wall to a neighbor who recorded them—were held not to be a protected "oral communication." For wire and electronic communications, the all-party consent rule applies per se, with no exception for public or semi-public settings. There is no statutory carve-out for recordings made inside one’s own home, and location alone does not determine whether the all-party consent rule applies. The analysis turns on whether the conversation is a protected "oral communication" (for in-person talks) or a wire/electronic communication (for phone calls and electronic messages).
Recording in the workplace and other shared spaces
Workplace conversations can implicate Maryland’s wiretap law depending on the type of communication and the setting. Phone calls made at work are "wire communications" protected per se, so all-party consent is required to record them. For in-person workplace conversations, the analysis hinges on whether the conversation qualifies as a protected "oral communication" under the REOP test. A conversation in a shared office, break room, or cubicle may lack a reasonable expectation of privacy if it is conducted in a manner audible to others or in a space with limited privacy. Conversely, a private meeting in a closed office or conference room where participants speak quietly may satisfy the REOP test. Maryland courts have not created a blanket rule for workplace conversations; each case turns on the specific facts, including volume, location, and whether steps were taken to exclude others. Employers and employees should exercise caution when recording workplace interactions, as violations can trigger both criminal and civil liability.
Biometric and voice data: Maryland’s 2024 privacy law
Maryland’s Online Data Privacy Act of 2024 (MODPA), effective October 1, 2025, treats biometric data as a category of "sensitive data" and imposes strict limits on its collection and processing. Under MODPA, a controller may not collect or process sensitive data concerning a consumer unless the collection or processing is strictly necessary to provide or maintain a specific product or service requested by the consumer; consent alone does not cure a non-strictly-necessary collection. Biometric data includes a voice print generated by automatic measurements of biological characteristics used to uniquely authenticate a consumer’s identity, but excludes raw audio or video recordings themselves. MODPA applies to entities processing the personal data of at least 35,000 Maryland consumers in the prior calendar year, or at least 10,000 consumers if more than 20% of gross revenue comes from the sale of personal data. Enforcement is by the Attorney General only, with a mandatory 60-day cure period that sunsets on April 1, 2027. MODPA does not create a private right of action and contains no per-violation statutory damages. For voice-biometric processing in Maryland, if the use is not strictly necessary to deliver the requested product or service, collection is prohibited regardless of consent; sale of biometric data is prohibited outright.
The full picture
Every layer of the law, not just the headline rule
Statute · Penalty: mixed
Md. Code Ann., Cts. & Jud. Proc. §§ 10-401 to 10-414 (Maryland Wiretapping and Electronic Surveillance Act), with the core interception prohibition and all-party-consent exception at § 10-402(a) & (c)(3), penalties at § 10-402(b), and the private civil action at § 10-410.
In-person vs. phone & video calls
Maryland's statute draws a meaningful line between "wire communications" (e.g., phone calls) and "oral communications" (in-person speech). Wire communications are protected essentially per se — consent of all parties is required regardless of whether a REOP analysis would otherwise apply. "Oral communication" is statutorily defined (§10-401(13)(i)) as "any conversation or words spoken to or by any person in private conversation" (§10-401(13)(ii) separately excludes electronic communications from the definition); the "expectation... not subject to interception, under circumstances justifying that expectation" gloss is not statutory text — it is the federal Title III definition (18 U.S.C. §2510(2)), applied by Maryland courts as the judicially-derived reasonable-expectation-of-privacy test (i.e., limited to private conversations) — so in-person speech is only protected where a reasonable expectation of privacy (Katz two-prong test) exists; loud, public, or otherwise non-private in-person speech falls outside the Act entirely regardless of consent. Electronic communications (e.g., text/email) are covered similarly to wire communications. Net effect for the wearable-device use case: an all-party-consent rule applies to phone calls and to in-person conversations that are legally "private," but no wiretap-consent obligation attaches to in-person speech in public/non-private settings (disputes on the street, interactions with police during a public stop, etc.) because such speech isn't a protected "oral communication" in the first place.
Recording in public
There is no explicit "public place" exception written into the statutory text, but the same result is achieved through the statutory definition of "oral communication" in §10-401, which (per Maryland courts, e.g., Malpas v. State, 695 A.2d 588 (Md. Ct. Spec. App. 1997); see also Agnew v. State, 461 Md. 672, 197 A.3d 27 (2018), cited by secondary sources as probable additional Court of Appeals authority for this proposition, not independently full-text-verified) is limited to conversations made under circumstances justifying an expectation that they are not subject to interception. Maryland courts apply the two-pronged Katz v. United States reasonable-expectation-of-privacy test (subjective expectation of privacy + one society recognizes as reasonable) to decide whether a given in-person conversation is a protected "oral communication." Conversations conducted in public, in a loud voice, or otherwise observable/audible to third parties (as in Graber's public roadside traffic stop, and Malpas's loud in-home conversation overheard next door) generally fall outside the statute's protection, meaning no all-party consent is legally required to record them. Note this REOP gloss applies to in-person ("oral") communications only — Maryland courts have held wire communications (telephone calls) are protected regardless of a case-by-case REOP showing.
Recording at home
No express statutory carve-out exists for recording inside one's own home. Location is not dispositive — Maryland courts apply the same Katz-derived reasonable-expectation-of-privacy analysis regardless of where the speech occurs. In Malpas v. State, 116 Md. App. 69, 695 A.2d 588 (Md. Ct. Spec. App. 1997), a third-party witness (Craigie, not the defendant) speaking loudly in his own apartment lost wiretap protection -- his shouted statements, audible through a shared wall and recorded by the defendant on a handheld cassette recorder, were held to be "the functional equivalent of statements knowingly exposed to the public," so no REOP existed despite Craigie being in his own home — the court held he had no reasonable expectation of privacy despite being in his home. So being in one's own home raises the likelihood a REOP exists but does not guarantee it, and does not itself trigger a stricter or separate rule; the general all-party-consent/oral-communication-privacy framework of §10-401/10-402 still governs.
Recording the police
Maryland has no statutory exception permitting citizens to record on-duty officers without consent as such — instead, case law holds that officers conducting their public duties (e.g., a traffic stop on a public highway) generally lack a reasonable expectation of privacy in their on-the-job statements, so the encounter falls outside the definition of a protected "oral communication" altogether. The leading (though only trial-court-level, non-appellate) authority is State v. Graber, Harford Co. Cir. Ct., Crim. No. 12-K-10-000462 (Md. Cir. Ct. Sept. 27, 2010) (unreported), in which Judge Emory Plitt dismissed wiretap felony charges against a motorcyclist who helmet-cam-recorded a plainclothes state trooper during a traffic stop, holding "the Trooper did not have a reasonable expectation of privacy in the conversation which society would be prepared to recognize as reasonable" given the stop occurred on a public highway. Maryland's then-Attorney General (Gansler) reached the same conclusion in a 2010 opinion letter. No published Maryland appellate (Supreme Court of Maryland or Appellate Court of Maryland) decision has definitively ratified this holding, so it should be treated as strong persuasive authority, not binding precedent. Separately, on the federal constitutional side, Maryland sits in the U.S. Court of Appeals for the Fourth Circuit (with Virginia, West Virginia, North Carolina, and South Carolina). The Fourth Circuit has recognized a First Amendment right to record/livestream police performing their duties in public: Sharpe v. Winterville Police Dep't, 59 F.4th 674 (4th Cir. 2023), held that livestreaming a police traffic stop is speech protected by the First Amendment (though it affirmed qualified immunity for the individual officers because the specific right to livestream, as opposed to record generally, was not yet "clearly established" at the time of that incident). This aligns Maryland's circuit with the broader trend among federal appellate courts recognizing a right to record police in public.
Video-only capture (no audio)
Not restricted by this statute. The Wiretap Act's prohibition applies only to the interception of a "wire, oral, or electronic communication" as those terms are defined in § 10-401; "oral communication" is defined as spoken words/conversation, and there is no equivalent statutory category covering silent visual images. A video recording made without a simultaneous audio track therefore does not "intercept" any statutorily defined communication and falls outside the Act, regardless of consent — this is the consistent interpretation applied by Maryland practitioners and secondary sources (no published appellate case was found squarely holding this, but it follows directly from the statutory text confirmed against the official mgaleg.maryland.gov version of §§10-401/10-402, since only audio content is defined as regulated "communication"). The moment audio is captured alongside the video, the ordinary all-party-consent / reasonable-expectation-of-privacy analysis under §10-402 applies to the audio track.
What counts as a “private” conversation →
Maryland's Wiretap Act (Cts. & Jud. Proc. §§10-401 to 10-414) protects only "oral communication," which §10-401(13)(i) defines as "any conversation or words spoken to or by any person in private conversation" (§10-401(13)(ii) separately excludes electronic communications from the term) — confirmed verbatim, including exact subsection lettering, via independent live fetch of the official statute at mgaleg.maryland.gov. The undefined phrase "private conversation" is filled in by case law applying the two-pronged Katz reasonable-expectation-of-privacy (REOP) test: subjective expectation of privacy + one society recognizes as reasonable. On-point, independently-confirmed authority applying this test to §10-401(13)(i)'s "private conversation" element: Malpas v. State, 116 Md. App. 69, 695 A.2d 588 (Md. Ct. Spec. App. 1997) — quoting the statute and holding that a third party's (Richard Craigie's) loud, profane statements, made in Craigie's OWN apartment and audible through a shared wall to defendant Malpas in the adjoining unit (where Malpas recorded them on a handheld cassette recorder), were NOT a protected "oral communication" because Craigie's shouting was "the functional equivalent of statements knowingly exposed to the public" — REOP defeated despite Craigie being in his own home. IMPORTANT FACTUAL CORRECTION to the original draft (and to language already present in the live dataset row's own_home_exception_notes): it was Craigie — a third party/witness in the underlying shooting prosecution, not "the defendant" — whose statements lost protection, and a recording device (cassette recorder) WAS used, even though the sound was already naturally audible through the wall without amplification. Framing it as "a defendant... overheard by a neighbor... without any device" mischaracterizes who was recorded and by what means. Secondary reporting (Reporters Committee for Freedom of the Press recording-law guide) cites Agnew v. State, 461 Md. 672, 197 A.3d 27, 35 (Md. 2018) — a genuine Court of Appeals of Maryland (the state's highest court) case, confirmed to exist via vLex under that exact citation — as the source for the proposition that Maryland's highest court has held the Act protects only conversations in which parties have a REOP. I could not pull the specific REOP passage from the full Agnew opinion this session (only excerpts about its one-party-consent/admissibility holding on a self-recorded phone call were retrievable), so this citation should be treated as probable-but-not-fully-verified pending a full-text read. SUBSTANTIVE CORRECTION — remove/do not rely on Fearnow: the original draft cited Fearnow v. Chesapeake & Potomac Tel. Co. of Md., 342 Md. 363, 676 A.2d 65 (1996), as "the leading authority" for "MD's highest court applying Katz to the Act's oral-communication element." Independent research (vLex case summary, cross-checked against a lawpipe.com case digest) shows this is a mischaracterization: Fearnow actually concerned an employer's interception of an employee's WORKPLACE TELEPHONE calls — i.e., "wire communication," not "oral communication" — and the Court of Appeals' actual 1996 disposition turned on a procedural question (whether Fearnow's trial counsel adequately preserved an objection to a flawed jury instruction under Md. Rule 2-520(e)), not on a substantive ruling construing "oral communication" or applying Katz to §10-401. This same Fearnow mischaracterization also already appears, uncorrected, in the live dataset row's own public_place_exception_notes field ("per Maryland courts, e.g., Fearnow... and Malpas... [courts] apply the two-pronged Katz... test") — this is a pre-existing citation error in the live data, not one introduced by this analysis. Separately, State v. Graber, Harford Co. Cir. Ct., Crim. No. 12-K-10-000462 (Md. Cir. Ct. Sept. 27, 2010) (unreported trial-court opinion; a state trooper had no REOP in his statements during a public roadside traffic stop) is consistent with extensive contemporaneous ACLU/RCFP press reporting and the dataset row's own prior independent verification; I could not independently re-fetch it this session (legal databases returned 403s and WebSearch quota was exhausted), so I am relying on convergent secondary corroboration rather than a fresh primary-source read, same limitation the original researcher disclosed. This REOP gate applies ONLY to in-person "oral communication" — "wire communication" (§10-401(18): phone calls) and "electronic communication" (§10-401(5): text/email) have no "private"/REOP qualifier at all in their statutory definitions (confirmed verbatim via live fetch) and are protected essentially per se, bypassing the gate entirely. An in-person conversation in Maryland must first qualify as a "private conversation" under §10-401(13)(i) — via the Katz-derived REOP test, for which Malpas v. State, 695 A.2d 588 (Md. Ct. Spec. App. 1997), is solid, independently-confirmed on-point authority (with Agnew v. State, 197 A.3d 27 (Md. 2018), as probable additional highest-court authority per secondary sourcing, not independently full-text-verified this session) — to count as a protected "oral communication" at all. If it clears that threshold, Maryland's all-party-consent rule (§10-402(c)(3), confirmed verbatim: interception is lawful only where the intercepting party "is a party to the communication" and "all of the parties to the communication have given prior consent to the interception") requires every participant's consent to record it. If it doesn't clear the threshold — e.g., statements loud enough to be "the functional equivalent of statements knowingly exposed to the public" (Malpas), or an officer's statements during a public traffic stop (per the unreported Graber trial-court decision) — no one's consent is required at all. Phone calls ("wire communication") and electronic communications (text/email) skip this gate altogether and remain all-party-consent-protected per se regardless of any REOP showing, since neither §10-401(18) nor §10-401(5) contains a "private"/REOP qualifier. CORRECTION: Fearnow v. Chesapeake & Potomac Tel. Co. of Md. (1996), previously cited as the mechanism's "leading authority," does not actually support it — it is a wire-communication/workplace-telephone case whose Court of Appeals disposition rested on jury-instruction-preservation procedure, not a substantive REOP ruling on "oral communication." It should not be cited as gate-mechanism authority (this same error currently exists, uncorrected, in the live dataset row's public_place_exception_notes field as well).
Maryland Online Data Privacy Act of 2024 (MODPA) — a comprehensive consumer data privacy law that treats biometric data as a category of "sensitive data," NOT a dedicated BIPA-style biometric statute. Standalone "Biometric Data Privacy" bills (e.g., HB 33 of 2023, "Commercial Law – Consumer Protection – Biometric Data Privacy") were introduced but died in committee; MODPA is the only biometric-related privacy law actually enacted in Maryland. — MODPA's "biometric data" definition (§ 14-4701(d)) explicitly includes "a voice print" as data "generated by automatic measurements of the biological characteristics of a consumer that can be used to uniquely authenticate a consumer's identity." It excludes a raw audio/video recording itself, but not data (e.g., a voiceprint template) generated from a recording if generated to identify a specific consumer — so a voiceprint extracted from audio for speaker identification qualifies. Biometric data is an enumerated category of "sensitive data" (§ 14-4701(gg)). CORRECTION to the original draft: I pulled the verbatim, currently-in-force text of § 14-4707(a)(1) directly from mgaleg.maryland.gov: "Except where the collection or processing is strictly necessary to provide or maintain a specific product or service requested by the consumer to whom the personal data pertains, [a controller may not] collect, process, or share sensitive data concerning a consumer." This is a SINGLE-condition test — strict necessity — with NO consent-based alternative or additional gate anywhere in that clause. The original draft mischaracterized this as a two-part test requiring both strict necessity AND separately-obtained consumer consent ("strict necessity does not substitute for consent; both conditions must be met"); that is not supported by the current statutory text. Cooley's independent secondary analysis corroborates the corrected reading, noting MODPA notably lacks the consent-can-substitute-for-necessity option found in other states' comprehensive privacy laws (e.g., Virginia CDPA) — making MODPA's sensitive-data standard stricter, not laxer, than a consent-based regime. Practical implication for live.law: if voice-biometric processing in Maryland is not "strictly necessary to provide or maintain a specific product or service requested by the consumer," obtaining user consent does NOT cure the violation under § 14-4707(a)(1) — the collection is simply prohibited regardless of consent. Sale of sensitive data (including biometric data) is prohibited outright with no exception (§ 14-4707(a)(2)). MODPA also does not require a separately published written biometric retention/destruction policy as a BIPA-style precondition, and imposes no per-violation statutory damages. Applicability is gated by a size threshold (§ 14-4702: ≥35,000 MD consumers processed in the prior calendar year, or ≥10,000 consumers plus >20% of gross revenue from selling personal data) — confirmed verbatim — so a small-scale Maryland voice-enrollment rollout may fall outside MODPA's scope entirely, unlike BIPA which has no size threshold.
Attorney ethics (ABA Formal Op. 01-422) →
Independently re-verified and the researcher's conclusion holds. (1) Rule text: Md. Rule 19-308.4(c) was confirmed against a secondary source that publishes the rule's text, reading exactly "(c) engage in conduct involving dishonesty, fraud, deceit or misrepresentation" — matching the quote in the entry verbatim, and confirmed as Maryland's word-for-word adoption of ABA Model Rule 8.4(c). (2) The CRS Report (R42650, Aug. 9, 2012) was independently pulled and read directly (not taken on faith) — its table of contents lists a 38-jurisdiction-plus-D.C. state-by-state attachment (Alabama, Alaska, Arizona, California, Colorado, D.C., Florida, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, New Hampshire, New Mexico, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, Wisconsin) and Maryland is indeed nowhere in that list — this directly corroborates the researcher's central evidentiary point that even CRS's dedicated survey of this exact question found no Maryland authority. (3) Independent searches (DuckDuckGo queries for Maryland Attorney Grievance Commission discipline cases involving recording, and for MSBA ethics opinions on lawyers taping conversations) turned up no on-point Maryland opinion or case; the only Rule 19-308.4(c) case surfaced (Attorney Grievance Comm'n v. Hecht) involves unrelated dishonesty (lost documents, billing misrepresentation), not recording. (4) The claim that MSBA's and the Maryland Judiciary's sites resist automated/public search was independently reproduced: direct sub-page fetches to mdcourts.gov and msba.org ethics-opinion paths returned 403/404 errors and the msba.org site-search for "recording" returned no substantive hits, even though the top-level domains (courts.state.md.us/attygrievance, msba.org) themselves load fine (HTTP 200) — consistent with the researcher's note that the archive isn't well indexed rather than that it doesn't exist. No errors were found in the entry; the "no_direct_authority" classification is correct rather than an overstatement, and "medium" confidence (not "low") is justified by the strength of the CRS-omission corroboration despite the residual gap that a subscription-gated database search wasn't performed.
Can you personally sue over a violation?
Yes — this state gives a private right of action, not just criminal/regulatory enforcement.

Common situations
Specific questions people actually ask
Can I record as a guest in someone else's home?
It depends on the specifics of the moment — Maryland doesn't give a guest the same clear leeway a homeowner gets, so this is closer to a case-by-case call than a fixed yes or no.
Read the full explainer →What if I'm on a call with someone in another state?
Play it safe: if either state on the call requires everyone's okay to record, treat the whole call that way — don't assume Maryland's rule is the only one that matters just because you're the one wearing the glasses.
Read the full explainer →If it's legal to record, can it still be used against me later?
Usually, yes. Being legal to record and being protected from a future court case are two different questions — a legal recording can generally still be obtained by the other side later. A third person being briefly or incidentally present doesn't automatically wreck that protection here, but it's still not something to count on. Recording your own conversation with your own attorney is a separate, more protected situation, but almost everything else — a landlord, a police officer, a family member — isn't automatically off-limits to opposing counsel just because it was legal to capture.

Can I record a conversation in my own home without telling the other person?
It depends on whether the conversation is a protected "oral communication" under the Katz two-prong reasonable-expectation-of-privacy test. If you are speaking quietly and taking steps to exclude others, you likely need consent to record. But if you are speaking loudly enough that others could overhear—even in your own home—a court might rule the conversation was not private. Maryland courts have said being in your own home does not guarantee privacy; in Malpas v. State, Richard Craigie’s loud statements in his apartment, audible through a shared wall and recorded by a neighbor using a handheld cassette recorder, were held not to be a protected "oral communication." The outcome turns on the specific facts, including volume and whether the speech was effectively exposed to unintended listeners.
Can I record a police officer during a traffic stop?
Yes, you can generally record police officers performing their official duties in public during a traffic stop without their consent, but this is governed by persuasive, non-binding authority. In State v. Graber, a Maryland trial court dismissed wiretap felony charges against someone who recorded a state trooper during a public roadside traffic stop, finding the trooper had no reasonable expectation of privacy in the conversation. While this decision is not binding on all Maryland courts and no published appellate decision has definitively ratified it, it is considered strong persuasive authority. The Fourth Circuit has also recognized a First Amendment right to record or livestream police performing their duties in public. However, because State v. Graber is an unreported trial-court decision, its holding should be read narrowly to its own facts—a public roadside traffic stop—and not generalized to all police-present situations. If the encounter moves indoors or becomes less clearly public, the rules may change, and attorney review is recommended.
Do I need consent to record a phone call in Maryland?
Yes. Under §10-402(c)(3), Maryland’s law requires all parties to consent before recording a phone call. This applies to both landline and mobile calls, and the law treats phone calls as protected communications per se. There is no exception for public or semi-public settings; the all-party consent rule applies automatically to wire communications.
What’s the penalty for recording someone without consent in Maryland?
Illegally intercepting a communication without the statutorily required consent is a felony under §10-402(b), punishable by up to five years in prison and a $10,000 fine. The person you recorded can also sue you for damages under §10-410, which provides for at least $100 per day of violation or $1,000 in liquidated damages (whichever is greater), plus punitive damages and reasonable attorney’s fees. These penalties apply even if you did not intend to break the law, and civil suits may proceed even if no criminal charges are filed.
Can I record a video of someone without their consent if I don’t capture audio?
Yes. Maryland’s wiretap law restricts only the interception of audio communications. A silent video, even in a private place, is not restricted by the law. However, if your video includes any audio—even accidentally—the all-party consent rule applies to that audio track. This means that if you are recording video of a conversation, you must ensure no audio is captured unless every person involved consents.
Does Maryland have any exceptions for recording in my own home?
No. Maryland’s wiretap law does not include an express exception for recordings made inside one’s own home. Location is not dispositive; courts apply the same Katz-derived reasonable-expectation-of-privacy analysis regardless of where the speech occurs. In Malpas v. State, Richard Craigie’s loud statements in his own apartment—audible through a shared wall and recorded by a neighbor using a handheld cassette recorder—were held not to be a protected "oral communication," demonstrating that even in one’s own home, loud speech can forfeit protection. The analysis turns on whether the conversation qualifies as a protected "oral communication" under the REOP test.
Can I record a conversation in a public place like a park or sidewalk?
Generally, yes—if the conversation is conducted in a manner that exposes it to public observation or audibility. Maryland courts apply the Katz two-prong REOP test to determine whether an in-person conversation is a protected "oral communication." Conversations conducted in public, in a loud voice, or otherwise observable or audible to third parties generally fall outside the statute’s protection, meaning no all-party consent is legally required. However, if the participants take steps to seclude themselves—such as speaking quietly in a corner or huddling away from passersby—the conversation may still qualify as private. The outcome depends on the specific facts of each case.
Does Maryland’s privacy law restrict the use of voice biometrics or voice prints?
Yes, under the Maryland Online Data Privacy Act of 2024 (MODPA), which treats biometric data—including voice prints—as "sensitive data." A business may not collect or process sensitive data unless it is strictly necessary to provide or maintain a specific product or service requested by the consumer; consent alone does not cure a non-strictly-necessary collection. MODPA applies to entities processing the personal data of at least 35,000 Maryland consumers in the prior calendar year, or at least 10,000 consumers if more than 20% of gross revenue comes from the sale of personal data. Enforcement is by the Attorney General only, with a mandatory 60-day cure period that sunsets on April 1, 2027. MODPA does not create a private right of action and contains no per-violation statutory damages.
