Recording Law for Family Law in Maryland

Maryland’s wiretap law requires every person’s consent before you can legally record a private conversation. The law defines a private conversation as any spoken exchange where the speakers have a reasonable expectation that their words won’t be overheard or recorded, as set out in Md. Code Ann., Cts. & Jud. Proc. §10-401(13)(i): "'Oral communication' means any conversation or words spoken to or by any person in private conversation." This rule applies whether the conversation happens in person, over the phone (wire communications), or through electronic messages like texts or emails (electronic communications). Wire communications are protected essentially per se, meaning they require all-party consent regardless of a case-by-case reasonable-expectation-of-privacy analysis. If you record a private conversation without everyone’s consent, you could face felony charges and a civil lawsuit. The only exception is if you are a participant in the conversation and everyone else has agreed to the recording, as provided in §10-402(c)(3).

Not every spoken exchange is protected. Maryland courts apply a two-prong reasonable-expectation-of-privacy (REOP) test—subjective expectation plus one society recognizes as reasonable—to determine whether a conversation qualifies as a "private conversation" under §10-401(13)(i). If the conversation is loud enough to be overheard by others nearby, or if it happens in a public place where bystanders could naturally hear, it may not be private. For example, a shouting match on a street corner isn’t a private conversation, even if the people involved think they’re having a private argument. But if two people are speaking quietly in a parked car with the windows up, or in a closed room where their voices don’t carry outside, that’s likely a private conversation. The law doesn’t give special protection just because you’re in your own home—if your neighbor can hear you yelling through a thin wall, the conversation may not be private. In Malpas v. State, 116 Md. App. 69, 695 A.2d 588 (Md. Ct. Spec. App. 1997), a third party’s loud, profane statements made in his own apartment and audible through a shared wall to a neighbor in the adjoining unit were held not to be a protected "oral communication," because the shouting was "the functional equivalent of statements knowingly exposed to the public." The court emphasized that the defendant recorded the statements using a handheld cassette recorder, even though the sound was already naturally audible through the wall.

Recording police officers during a public traffic stop or similar public encounter is generally allowed in Maryland. In State v. Graber, Harford Co. Cir. Ct., Crim. No. 12-K-10-000462 (Md. Cir. Ct. Sept. 27, 2010) (unreported), a trial court ruled that an officer performing public duties on a public roadway has no reasonable expectation of privacy in statements made during the stop. While this decision is not binding on other courts and has not been ratified by a published Maryland appellate decision, it is considered strong persuasive authority. The same logic applies to other public officials acting in their official capacity in public spaces. However, if the officer steps into a private area, like a home or a closed office, the rules for private conversations apply again. Always keep the recording in plain view and avoid interfering with police duties.

Maryland’s wiretap law contains no express exception for recording inside one’s own home; courts apply the same Katz-derived REOP analysis regardless of location. In Malpas, the fact that the loud speech occurred in the speaker’s own apartment did not guarantee protection, because the court focused on whether the speech was exposed to unintended listeners. Electronic communications (texts, emails) are treated like wire communications and are protected essentially per se, requiring all-party consent regardless of a REOP showing. Loud, public, or otherwise non-private in-person speech falls outside the Act entirely, meaning no consent is legally required to record it. The statute also draws a meaningful line between "wire communications" (e.g., phone calls) and "oral communications" (in-person speech), with wire communications protected regardless of a case-by-case REOP analysis.

Maryland’s wiretap law only restricts the recording of spoken words. If you record video without capturing audio, the law does not apply. For example, using a body camera to document a custody exchange without audio is not covered by the all-party consent rule. But as soon as your recording includes any spoken words, the law’s consent requirement kicks in. This distinction matters for wearable devices that can record video but may also pick up nearby conversations accidentally. 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.

Recording a private conversation without consent in Maryland is a felony punishable by up to five years in prison and a $10,000 fine under §10-402(b). You could also face a civil lawsuit where the other person can sue for damages, attorney’s fees, and legal costs under §10-410. The law allows the person whose conversation was recorded to sue even if they weren’t the one who recorded it. The penalties apply to interception of wire, oral, or electronic communications, not to the mere act of sending or receiving electronic messages. The statute provides a mixed penalty structure: felony penalties for interception and certain divulgence offenses, with lesser misdemeanor-level fines/imprisonment for other offenses. The only exception is if you are a participant in the conversation and everyone else has agreed to the recording, as provided in §10-402(c)(3).

Maryland’s Online Data Privacy Act of 2024 (MODPA), effective October 1, 2025, treats biometric data as a category of "sensitive data" under Md. Code Ann., Com. Law §14-4701(gg). "Biometric data" 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" (§14-4701(d)). MODPA prohibits the collection or processing of sensitive data unless it is strictly necessary to provide or maintain a specific product or service requested by the consumer (§14-4707(a)(1)). Critically, MODPA does not allow consent to substitute for strict necessity; the collection is simply prohibited if not strictly necessary, regardless of consent. Sale of sensitive data (including biometric data) is prohibited outright with no exception (§14-4707(a)(2)). MODPA applies to controllers processing the personal data of at least 35,000 Maryland consumers in the prior calendar year, or at least 10,000 consumers plus deriving more than 20% of gross revenue from the sale of personal data (§14-4702). Enforcement is by the Attorney General only, with a mandatory 60-day cure period before suit (§14-4714). MODPA creates no private right of action and imposes no per-violation statutory damages.

Imagine you’re at a public park for a court-ordered custody exchange. Your co-parent starts yelling at you in front of other parents and children nearby. You turn on your phone to record what’s happening, hoping to document their behavior for future court proceedings. Because the argument is loud and happening in a public place where others can hear, it’s not a private conversation under Maryland law. Your recording is legal even without your co-parent’s consent. But if the argument moves to a quiet corner of the park where no one else can hear, or if you secretly record a private conversation in your home, you would need everyone’s consent to avoid breaking the law. In Malpas, a third party’s loud speech recorded by a neighbor through a shared wall using a handheld cassette recorder was held not to be a protected "oral communication," underscoring that volume and audibility to unintended listeners—not location alone—determine whether a conversation is private.
