Is it legal to record phone calls in Maryland?
Only with everyone’s consent. Maryland is an all-party consent state: every participant in a phone call must consent to being recorded. The standard mechanism is a clear announcement — a party who stays on the line after hearing “this call may be recorded” is generally treated as having consented.
What Maryland law says
Maryland is one of roughly a dozen US states that require all parties’ consent to record a phone call. Recording without consent can carry criminal penalties and civil liability, so the practice to adopt is simple: announce the recording at the start of every call, or use a tool that announces it for you.
Maryland requires all parties to consent before anyone lawfully intercepts a wire, oral, or electronic communication. Section 10-402 makes nonconsensual interception a felony, and the Act is deliberately stricter than federal law — there is no general citizen one-party consent exception. Telephone and electronic communications are protected regardless of privacy expectations, while in-person oral communications require a showing that the parties had a reasonable expectation of privacy.
"Except as otherwise specifically provided in this subtitle, it is unlawful for any person to: (1) willfully intercept, endeavor to intercept, or procure any other person to intercept or endeavor to intercept any wire, oral, or electronic communication." — Md. Code Ann., Cts. & Jud. Proc. § 10-402(a). All-party consent exception: "It is lawful under this subtitle for a person to intercept a wire, oral, or electronic communication if that person is a party to the communication or has the prior consent of one of the parties to the communication, only if all of the parties to the communication have given prior consent." — § 10-402(c)(3).
Federal law permits one-party consent under 18 U.S.C. § 2511(2)(d), but Maryland's Wiretap Act requires all-party consent for lawful interception by private citizens — a deliberate choice the legislature made when patterning the Act on Title III but adding stricter protections. Seal v. State confirmed Maryland's supervision exception is narrower than federal 'color of law' provisions. A recording lawful under federal standards can still be a Maryland felony, trigger civil damages under § 10-410, and be suppressed in court proceedings.
Maryland is a true all-party consent state for phone and electronic communications: if you are a party to the call, you still need every other party's consent before recording. Fearnow v. Chesapeake & Potomac Telephone Co. held that telephone conversations are protected by the Wiretap Act regardless of whether the parties had a reasonable expectation of privacy — a stricter rule than for in-person conversations, which are only protected when the parties reasonably expected privacy (Agnew v. State). Consent must be actual prior consent from all parties; Maryland's one-party consent provision for law enforcement (§ 10-402(c)(2)) requires prior direction and supervision of an investigative officer and does not create a general citizen exception. Recording with criminal or tortious purpose is illegal even with consent (§ 10-402(c)(3)). A wrinkle: Agnew v. State held that a party who records a conversation cannot use the Wiretap Act to suppress that recording against themselves — the Act protects non-consenting parties, not secret recorders seeking to block their own evidence. Martin v. State created a separate quirk holding that cell phones are excluded from the definition of 'electronic, mechanical, or other device,' though Holmes v. State later limited that analysis.

| Calls with people in other states | The stricter state's rule may apply — when in doubt, disclose. |
What breaking the law costs in Maryland
Violating § 10-402(a) is a felony punishable by up to five years in prison and a fine of up to $10,000. A second or subsequent offense carries up to 10 years and a fine of up to $10,000.
Yes — § 10-410 authorizes any person whose wire, oral, or electronic communication is intercepted, disclosed, or used in violation of the Act to bring a civil action for the greater of actual damages or $100 per day of violation ($1,000 minimum), plus punitive damages, attorney's fees, and litigation costs. Illegally intercepted communications are inadmissible in any proceeding under § 10-402(a)(2)-(3) when offered against a party who did not consent.
Exceptions worth knowing
- All parties to the communication have given prior consent (§ 10-402(c)(3)) — the primary lawful path for private recording
- Law enforcement interception under judicial warrant or the supervision exception with prior direction of an investigative officer (§ 10-402(c)(1)-(2))
- Telephone company employees and equipment operating in the ordinary course of business (§ 10-402(c)(4))
- In-person oral communications where no party has a reasonable expectation of privacy (Malpas v. Maryland) — does not apply to telephone calls
- Recording with criminal or tortious purpose is never lawful, regardless of consent (§ 10-402(c)(3))
How Maryland courts have ruled
Statutes set the rule; cases show how it plays out when a recording ends up in front of a judge. These are real, decided cases under Maryland law.
What happened: A co-conspirator secretly recorded telephone conversations with Perry without Perry's consent. The State sought to introduce the recordings at Perry's trial.
The ruling: The Court of Appeals held the recordings were inadmissible because the interception violated the all-party consent requirement of § 10-402, and no statutory exception authorized a co-conspirator to record without all parties' consent.
What happened: Agnew secretly recorded a telephone conversation with an unidentified person and then moved to suppress the recording at his own trial, arguing the other party had not consented.
The ruling: The court held the Wiretap Act does not let a consenting recorder suppress his own recording — the Act protects non-consenting parties, not the person who made the illegal interception.
What happened: Neighbors in an adjoining apartment recorded a person speaking so loudly in his own apartment that they could hear without any sound-enhancing device.
The ruling: The court held the recording did not violate the Wiretap Act because the speaker had no reasonable expectation of privacy when talking loudly enough for neighbors to overhear without assistance.
What happened: The State used recordings made by a person acting at the direction of law enforcement without complying with Maryland's stricter supervision exception requirements for one-party consent interceptions.
The ruling: The court analyzed § 10-402(c)(2)'s supervision exception, holding Maryland requires investigative officers to direct and supervise any one-party consent interception — a standard stricter than federal law.
What happened: A husband used his cell phone to record conversations with his wife during divorce proceedings. The wife argued the recordings violated the Wiretap Act.
The ruling: The court held cell phone recordings are not covered by the Wiretap Act because 'telephone' is expressly excluded from the definition of 'electronic, mechanical, or other device' — though subsequent cases have narrowed this holding.
Personal calls vs. business calls in Maryland
Recording personal calls
Secretly recording phone calls in Maryland is a felony under § 10-402 regardless of whether you are on the call. Perry v. State confirms that even co-conspirators cannot secretly record without all-party consent. Agnew v. State adds that if you do record secretly, you cannot later suppress the recording at your own trial — the Act protects the people you recorded, not you. The Martin v. State cell-phone device exclusion creates a narrow path for recording on a cell phone's native functions, but recording through apps, standalone devices, or hidden microphones still triggers the all-party rule. For in-person conversations, Malpas shows that shouting loudly enough for neighbors to hear may defeat a privacy expectation, but ordinary private conversations require all-party consent. Announce you are recording and let the other person continue, or do not record at all.
Recording business calls
Maryland businesses must obtain all-party consent before recording any customer, vendor, or employee phone call. The standard 'this call may be recorded' disclosure at the start of the call, with the caller's decision to continue, satisfies § 10-402(c)(3). That applies to call centers, telehealth, collections, and sales teams calling Maryland numbers from out of state. Internal monitoring of employee calls also requires disclosure to all parties on the line. Document recording policies in writing and train staff — ignorance is not a defense, and civil liability under § 10-410 adds $100-per-day liquidated damages plus attorney's fees on top of criminal exposure.
Calls that cross state lines
Maryland courts have not issued a leading interstate choice-of-law decision, but Maryland's Wiretap Act is among the strictest in the country. If any participant is in Maryland, obtain all-party consent before recording. Out-of-state businesses recording Maryland residents under their home state's one-party rule risk felony prosecution and civil suits. Federal one-party consent under 18 U.S.C. § 2511(2)(d) does not preempt Maryland's stricter statute.
The safe way to record in Maryland
Whatever the local rule, one habit covers every situation: say the call is being recorded at the start. Consent is then on the recording itself, and cross-border calls stop being a legal puzzle. Callmark can play "This call may be recorded" automatically on your calls, so the disclosure never depends on your memory.

Common questions
Only if everyone on the call consents. An announcement at the start of the call, followed by the other party staying on the line, is the standard way consent is established in Maryland.
Courts have applied different states' laws to interstate calls, and you often can't verify where a mobile number is. The practical rule: assume the strictest state applies and disclose the recording.
In most states, continuing a call after a clear "this call may be recorded" announcement is treated as implied consent — the same mechanism customer-service lines rely on.
No. Maryland requires all parties to consent to intercept any wire, oral, or electronic communication. Being a participant does not create a one-party consent right for phone calls.
Only when the parties have a reasonable expectation of privacy. Malpas v. Maryland held that a person speaking loudly enough to be overheard by neighbors without a device may have no protected privacy interest. Telephone calls are always protected regardless of privacy expectations.
Generally no, if it was made without all-party consent. Illegally intercepted communications are inadmissible under § 10-402. Agnew v. State adds that the person who made the secret recording cannot invoke the Act to suppress it against themselves.
Martin v. State held that cell phones are excluded from the Wiretap Act's device definition, creating a narrow exception for native cell phone recording. Recording through separate apps or devices still requires all-party consent.
A felony carrying up to five years and $10,000 for a first offense, and up to 10 years for repeat offenses. Civil liability adds at least $1,000 or $100 per day of violation, plus punitive damages and attorney's fees.
Treat Maryland law as governing whenever a Maryland resident is on the call. Obtain all-party consent regardless of where the recorder is located.
