Recording Law for Phone & Video Calls in Colorado

Colorado lets you record any phone call you’re part of without telling the other person. This is called one-party consent, and it applies to calls made over regular phone lines, VoIP, and similar services. The key statute is Colorado’s wiretapping law, which makes it illegal for someone who isn’t a sender or intended receiver to overhear or record a telephone, telegraph, or electronic communication without the consent of either a sender or a receiver. Since you’re one of the parties, your consent is enough. Breaking this rule is a class 2 misdemeanor. The wiretapping statute does not cover video-only recordings because it targets transmitted communications, not local device storage.

If you record only video without capturing any audio, Colorado law does not treat that as wiretapping or eavesdropping. The wiretapping statute covers telephone, telegraph, or electronic communications, and the eavesdropping statute applies to oral conversations. Silent video recordings fall outside both statutes based on their text, which is audio/"communication"-centric, and this interpretation is corroborated by secondary sources, though no Colorado appellate case squarely holds video-only recording is categorically exempt. This means you can record a video call with the camera on and the mic off without worrying about Colorado’s consent rules. Just be careful not to capture audio by accident, because then the one-party consent rule would apply again.

Colorado courts and law enforcement recognize your right to record police officers performing their duties in public. A federal appeals court covering Colorado ruled that there is a First Amendment right to film on-duty police officers in public, and Colorado has a state law that says you have the right to lawfully record any incident involving a peace officer. You can keep the recording and the device, and an officer generally can’t seize it without your consent, a warrant, or a court order. If an officer deletes or seizes your footage without legal authority, you can sue for damages under a separate Colorado law that addresses law-enforcement interference with recordings.

Colorado’s eavesdropping law applies only to a person who is not visibly present during an in-person conversation or discussion and records or overhears it without the consent of at least one principal party. Courts apply a reasonable-expectation-of-privacy framework to determine whether a conversation is protected at all; conversations occurring in open public view (street, sidewalk, store) generally carry no reasonable expectation of privacy, so recording them is not eavesdropping even without consent. This framework is imported from the definition of "oral communication" in Colo. Rev. Stat. § 18-9-301(8), which requires the communication to be uttered under circumstances justifying a belief it was not subject to interception. This means you can record a loud argument in a park or a dispute in a grocery store aisle without breaking the law.

Imagine you’re on a Zoom call with a coworker to discuss a project. You decide to record the call to keep notes, but you don’t tell your coworker. In Colorado, this is legal because you’re part of the conversation and the state follows one-party consent. If you only record the video without audio, it’s also legal because silent video recordings aren’t restricted. But if you accidentally capture audio from a private family conversation happening in the background, that part would require consent, because it’s a separate oral conversation with a reasonable expectation of privacy.

Colorado has a limited exception allowing recording devices on your own premises, but only if used for a security or business purpose and with reasonable public notice of the use. This exception would not cover a purely personal argument at home without notice. There’s also no separate home-specific rule: if you’re visibly present during a conversation, you’re not “eavesdropping” even at home. Colorado does not have a marital or spousal exemption, so recording conversations with a spouse follows the same rules as any other conversation. Separately, Colorado’s wiretapping/eavesdropping statutes include an explicit exemption for news agencies using accepted tools and equipment to report or investigate a public and newsworthy event, set out in the same section that otherwise defines the offenses.

Colorado’s one-party consent rule applies at home the same way it applies everywhere else: if you are a visible participant in a conversation, you are not committing eavesdropping regardless of location. The only premises-based exception in the wiretapping/eavesdropping statutes requires the use to be for a security or business purpose and includes a notice requirement, so it does not broadly exempt home recordings. Colorado does not have a marital or spousal exemption, and the statutes do not create a special carve-out for disputes at home. Separately, Colorado’s wiretapping/eavesdropping statutes include an explicit exemption for news agencies using accepted tools and equipment to report or investigate a public and newsworthy event, set out in Colo. Rev. Stat. § 18-9-305(1).

Colorado’s wiretapping/eavesdropping statutes include an explicit exemption for news agencies using accepted tools and equipment to report or investigate a public and newsworthy event. This exemption is set out in Colo. Rev. Stat. § 18-9-305(1), which provides that nothing in the wiretapping or eavesdropping statutes shall be interpreted to prevent a news agency, or an employee thereof, from using the accepted tools and equipment of that news medium in the course of reporting or investigating a public and newsworthy event. The exemption operates independently of the one-party consent rule and allows journalists and news organizations to record interactions in public spaces without triggering the eavesdropping statute, even if not all parties consent.
