GPS and Audio at the Lake House
A divorce client hires you in Bangor. The client and spouse jointly own a cabin in Belgrade, Maine, but the spouse has been living there alone under a temporary court order. The spouse drives a vehicle titled only in the spouse's name, parked in the cabin driveway. The client gives you a spare key to the vehicle and asks you to place a magnetic GPS tracker under the rear bumper. The client also wants a small audio recorder hidden in the kitchen to capture the spouse's conversations with a new partner. The client says, 'Maine is one-party consent, so it's legal.' You have the cabin address, the spouse's work schedule, and a $2,000 budget. The client wants daily location reports and audio files within 48 hours. You have not placed anything yet. The spouse has no known criminal history, and no court order authorizes electronic monitoring.
1. Is the hidden kitchen audio recorder lawful? Explain the consent issue.
Read the worked answer
No, not on these facts. Maine's wiretap statute, 15 M.R.S. § 709 et seq., generally allows a party to a communication to record it. That is what 'one-party consent' means. But you and your client are not parties to the spouse's conversations with the new partner. Hiding a recorder to capture those private conversations is interception by someone who is not a participant.
The client's consent is not enough. The client's joint ownership of the cabin does not make the client a party to every conversation in the kitchen, and it does not authorize secret audio surveillance of a person living there under a court order. The recorder would also capture private activity beyond the target conversations.
Conclusion. Do not place the recorder. Advise the client in writing that the plan creates criminal and civil exposure and that a divorce court is unlikely to reward illegally obtained audio. If the client wants evidence of conversations, use lawful methods such as witness interviews or properly noticed testimony.
2. Can you place the GPS tracker on the spouse's vehicle? Discuss trespass, privacy, and the limits of private-actor status.
Read the worked answer
Private-actor status does not equal immunity. You are not police, so the Fourth Amendment does not apply directly. But that does not authorize trespass or invasion of privacy. The vehicle is titled only to the spouse. A spare key from your client does not give you authority to attach a device to the spouse's property.
Trespass and privacy. Placing a magnetic tracker under the bumper is a physical intrusion on the vehicle. Doing it in the cabin driveway may also involve the curtilage of the residence. Maine does not issue a PI license as a license to trespass. The temporary court order and the spouse's exclusive possession make the client's claimed authority weaker, not stronger.
Conclusion. Do not place the tracker without documented legal authority, such as a court order or the titled owner's informed written consent. If the client later owns or controls the vehicle, reassess with counsel. Otherwise, use public-road surveillance and other lawful observation.
3. What lawful alternatives and documentation should you recommend?
Read the worked answer
Lawful alternatives: conduct surveillance from public roads and public vantage points; photograph what is visible from public places; document times, locations, and vehicle descriptions; interview willing witnesses; review publicly available social media; and ask counsel about subpoenas or court orders for location or phone records in the litigation.
Do not: hide audio recorders in private rooms, attach trackers to the spouse's titled vehicle, enter the cabin without authority, or use the client's spare key to access the vehicle. Those choices can taint the case and create personal liability.
Documentation: put your advice in a letter or email to the client. State the facts you relied on, the legal concerns, the alternatives offered, and the client's response. Keep your surveillance logs and photographs. If the client insists on the unlawful plan, decline and document the refusal. This protects you and preserves the client's ability to use lawful evidence.
