Can police ask a spouse to disclose the other spouse’s phone passcode?

Lexi, Chatbot

I understand that this situation can be quite concerning. Has the search warrant already been executed, or is it still in the process?

Are there any specific details about the circumstances surrounding the warrant that you think are important?

Good day and welcome. Please give me a moment to review your question.

Note that I am a hearing impaired expert and so phone calls are difficult for me. Thank you for understanding.

Under U.S. constitutional law, even when police have a valid search warrant, they generally cannot compel a spouse to disclose the other spouse’s phone passcode unless that spouse voluntarily agrees to do so. The Fifth Amendment protects individuals from being forced to provide testimonial evidence that could be self-incriminating, and courts have interpreted this protection to extend to disclosing or entering passcodes, since doing so communicates knowledge of and access to potentially incriminating information. (U.S. Const. amend. V)

While the spouse who owns the phone can assert this privilege directly, the non-owner spouse has no legal authority to consent to a search or disclose access credentials for a device that is password-protected and personally owned by the other partner. Even with a warrant, law enforcement must obtain access through lawful forensic means or a compelled decryption order directed specifically to the device’s owner, not a third party.

Additionally, marital privilege principles reinforce this protection. Under federal common law and most state evidence codes, including those followed in Utah, a spouse cannot be compelled to testify against the other spouse in criminal proceedings or disclose confidential communications made during the marriage. Providing a passcode could arguably violate both the testimonial and marital communications privileges.

If police attempted to pressure or threaten a spouse to reveal such information, that conduct could render the evidence inadmissible as a constitutional violation under the exclusionary rule (Mapp v. Ohio, 367 U.S. 643). Therefore, the safest course of action for the non-owner spouse is to politely decline and state that they cannot provide or access the passcode, as any compelled disclosure could infringe both constitutional and evidentiary protections.

If the spouse voluntarily provides the passcode without coercion, police may legally use the information because it was obtained through consent, not compulsion. However, if the phone is clearly personal to the other spouse, courts can still suppress the evidence under the Fourth Amendment for exceeding the scope of valid consent, since the non-owner spouse had no authority to grant access to that device.
