Is it legal to record phone calls in Delaware?

Updated July 2026 · General information, not legal advice
Quick answer

Only with everyone’s consent. Delaware 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 Delaware law says

Delaware 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. Delaware’s statutes partly conflict; it is commonly treated as all-party in practice.

The statute
Delaware Wiretapping and Privacy Statutes

Delaware is effectively an all-party consent state for recording private conversations and phone calls, though two statutes conflict. Section 2402(c)(4) permits one-party consent wiretap interception, but section 1335(a)(4) independently requires the consent of all parties before intercepting any private message or conversation. No Delaware appellate court has resolved the conflict, and practitioners treat Delaware as all-party consent to avoid criminal exposure under both statutes.

"Intercepts without the consent of all parties thereto a message by telephone, telegraph, letter or other means of communicating privately, including private conversation." — 11 Del. C. § 1335(a)(4). The wiretap statute separately provides: "It is lawful … for a person to intercept a wire, oral or electronic communication where the person is a party to the communication or where one of the parties to the communication has given prior consent to the interception." — 11 Del. C. § 2402(c)(4).

Federal wiretap law (18 U.S.C. § 2511)

Federal law under 18 U.S.C. § 2511(2)(d) allows one-party consent recording, and Delaware's wiretap statute (§ 2402(c)(4)) mirrors that standard. But § 1335(a)(4) independently requires all-party consent for private conversations — a stricter rule the federal Wiretap Act does not displace. United States v. Vespe read the two statutes harmoniously, but state courts have not followed suit. A recording that satisfies federal law can still violate § 1335 and trigger misdemeanor prosecution plus civil liability under § 2402(f).

Delaware presents a genuine statutory conflict that makes recording law unusually uncertain on paper but conservative in practice. The wiretap chapter (§ 2402) mirrors the federal Wiretap Act and allows interception when the recorder is a party or has one party's consent. But the privacy offense at § 1335(a)(4) — a separate criminal statute — flatly prohibits intercepting any private message or conversation without the consent of all parties. No Delaware Supreme Court or Superior Court decision has held which statute controls when they conflict. The only judicial discussion is United States v. Vespe, a 1975 federal district court opinion (not binding on Delaware state courts) that read § 1335 as consistent with federal one-party consent. Given that both statutes carry criminal penalties — a Class E felony under § 2402(b) and a Class A misdemeanor under § 1335(c) — the Reporters Committee and practitioner guides uniformly advise treating Delaware as all-party consent. For businesses, a clear recording announcement at the start of the call followed by the other person's decision to continue is the standard compliance path.

What breaking the law costs in Delaware

Criminal exposure

Violating the wiretap prohibition in § 2402(a) is a Class E felony punishable by up to five years in prison and a fine of up to $10,000. Recording without all-party consent under § 1335(a)(4) is a Class A misdemeanor punishable by up to one year in jail and a fine of up to $2,300. Voyeurism-style recording in private spaces under § 1335(a)(6) or (a)(7) is a Class G felony.

Civil liability

Yes — § 2402(f) authorizes civil suits by the federal government, the State, or an aggrieved person for violations of § 2402 or § 2403, with actual damages, a $500-per-day liquidated-damages floor, punitive damages, and attorney's fees. A first-time violator who prevails in a prior civil action may face treble damages on subsequent violations.

Exceptions worth knowing

  • Wiretap one-party consent when the interceptor is a party or has a party's consent, provided the interception is not for a criminal or tortious purpose (§ 2402(c)(4)) — conflicts with § 1335(a)(4)
  • Law enforcement interception under judicial warrant or statutory emergency provisions (Chapter 24, Subchapter II)
  • Telephone company employees and equipment operating in the ordinary course of business (§ 2402(c)(5))
  • Consent of all parties — the safe harbor that satisfies § 1335(a)(4) regardless of the § 2402 conflict

How Delaware 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 Delaware law.

United States v. VespeCriminal case
389 F. Supp. 1359 (D. Del. 1975) · U.S. District Court for the District of Delaware · 1975 · Read opinion

What happened: Federal prosecutors used recordings made by a party to his own conversations in a criminal case. The defendant argued the recordings violated Delaware's § 1335 all-party consent requirement.

The ruling: The district court held that § 1335 was consistent with federal one-party consent and that a party may record his own conversation without all-party consent — but this is a non-binding federal opinion that Delaware state courts have never adopted.

Takeaway: Vespe is the only case addressing the § 2402/§ 1335 conflict, and relying on it in state court is risky — which is why practitioners default to all-party consent.
McDonald v. StateCriminal case
No. 482, 2015 (Del. Sept. 7, 2016) · Delaware Supreme Court · 2016 · Read opinion

What happened: A University of Delaware student used his cell phone camera to video-record a fellow student showering in a dormitory bathroom without consent.

The ruling: The Supreme Court affirmed the conviction for violation of privacy under § 1335(a)(6), holding the State established the corpus delicti through independent evidence corroborating the defendant's confession.

Takeaway: Delaware's privacy statute aggressively protects recording in private spaces — secret recording without consent carries real criminal consequences even when the recording is not a traditional phone call.
Rogers v. WilliamsPersonal / family
633 A.2d 747 (Del. Fam. Ct. 1993) · Delaware Family Court · 1993 · Read opinion

What happened: In a custody modification proceeding, a father sought to introduce a videotape of the interior of the mother's home that his new wife had recorded without the mother's knowledge or permission.

The ruling: The court excluded the videotape as wrongfully obtained through an unauthorized entry and secret recording, declining to let a party benefit from unlawful conduct even though the Fourth Amendment exclusionary rule did not directly apply to private actors.

Takeaway: Delaware courts will not reward secret recordings obtained through trespass or deception — even in family court where the evidence might seem relevant.
Coleman v. StateCriminal case
No. 192, 2021 (Del. Jan. 3, 2023) · Delaware Supreme Court · 2023 · Read opinion

What happened: Coleman moved to suppress evidence derived from a law enforcement wiretap of his phone, arguing the State violated inventory and notice requirements under § 2407 of Delaware's wiretap chapter.

The ruling: The Supreme Court affirmed denial of suppression, holding Coleman waived his § 2407 challenges by not raising them in a timely motion after learning of the wiretap.

Takeaway: Delaware strictly enforces procedural compliance with its wiretap chapter — both the government and private litigants face consequences for intercepting communications outside statutory authorization.

Personal calls vs. business calls in Delaware

Recording personal calls

Do not secretly record phone calls or private conversations in Delaware. The conflict between § 2402's one-party wiretap exception and § 1335(a)(4)'s all-party requirement means a secret participant recording could be charged under either statute. United States v. Vespe suggests a party might record his own conversation, but that 1975 federal opinion is not binding on Delaware state courts and has never been adopted by a Delaware appellate court. If you need a recording for a custody dispute, tenant issue, or harassment situation, announce that you are recording and let the other person decide whether to continue. Secret video in bathrooms, dressing rooms, or other private spaces is a separate felony under § 1335(a)(6)-(7), as McDonald v. State demonstrates.

Recording business calls

Delaware businesses should treat the state as all-party consent for every customer and employee call. Open with a recording disclosure — 'this call may be recorded' — and document that policy in employee handbooks and client terms. Because § 2402(f) provides civil damages with a $500-per-day floor plus attorney's fees, a business that records Delaware residents under a one-party theory risks both criminal prosecution and expensive civil litigation. Out-of-state call centers reaching Delaware numbers need the same all-party protocol. AI meeting recorders and automated transcription tools should obtain explicit consent from every participant before activating, since no Delaware court has yet addressed whether passive AI listening constitutes an 'interception' under either statute.

Calls that cross state lines

Delaware has no published choice-of-law decision governing interstate calls, but the dual-statute structure makes conservative compliance essential: if any participant is in Delaware, obtain all-party consent. A recorder in a one-party state who calls a Delaware resident without all-party consent gambles on an unsettled legal conflict while facing definite criminal exposure under § 1335(a)(4). Federal one-party consent does not preempt Delaware's stricter privacy statute.

The safe way to record in Delaware

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

Can I record a call I'm part of in Delaware?

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 Delaware.

What if the other person is in another state?

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.

Does an announcement count as consent?

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.

Is Delaware a one-party or all-party consent state?

Effectively all-party. Section 2402 allows one-party consent wiretap interception, but § 1335(a)(4) requires all-party consent for private conversations. No Delaware appellate court has resolved the conflict, so the safe answer is to get everyone's consent.

Can I record a call I'm on without telling the other person?

Risky at best. Vespe suggests a party may record his own conversation, but that non-binding 1975 federal opinion has never been adopted by a Delaware state court. Secret recording exposes you to a Class A misdemeanor under § 1335(a)(4) and a Class E felony under § 2402.

What are the penalties for illegal recording in Delaware?

Wiretap violations under § 2402 are a Class E felony (up to five years and $10,000). All-party consent violations under § 1335(a)(4) are a Class A misdemeanor (up to one year and $2,300). Civil suits under § 2402(f) add actual damages, $500-per-day liquidated damages, punitive damages, and attorney's fees.

Does a recording announcement count as consent in Delaware?

Yes, as a practical compliance measure. Announcing that a call will be recorded and letting the other person continue is the standard way businesses obtain the all-party consent § 1335(a)(4) requires.

Can I install a hidden camera in a private place in Delaware?

No. Section 1335(a)(2) prohibits installing recording devices in private places without consent, and subsections (a)(6)-(7) make voyeurism recording a Class G felony. McDonald v. State affirmed a conviction for bathroom recording.
