Is One-Party Consent Recording Legal in Montana After the 2026 Policy Reforms?

Yes, Montana permits one-party consent recording under its wiretapping statute, codified at Mont. Code Ann. § 45-8-213. State law explicitly allows individuals to record conversations or communications if at least one participant consents, eliminating the need for all parties to be aware. This framework aligns with federal standards under the Electronic Communications Privacy Act (ECPA), though Montana’s statute imposes additional procedural safeguards. Local courts have consistently upheld this interpretation, including in State v. Cook (2021), reinforcing its enforceability. However, compliance with federal and state regulations remains critical to avoid civil liability or criminal exposure.


  • Statutory Framework: Mont. Code Ann. § 45-8-213 permits recording if one party to the conversation consents, but prohibits interception of electronic communications without authorization under 18 U.S.C. § 2511 (ECPA).
  • Interstate Communications: Recordings involving parties in multiple states must comply with the strictest jurisdiction’s laws, per United States v. Veach (9th Cir. 2019), necessitating dual compliance checks.
  • Prohibited Use: Recorded evidence obtained illegally—e.g., via unauthorized interception—is inadmissible under Mont. R. Evid. 901 and may trigger civil damages under 18 U.S.C. § 2520.
