Step by step: hiring in Maine
- Define your question. What do you need to know, and what decision depends on it?
- Verify licensing. Look the detective up on the Maine State Police, Licensing website rather than relying on a license number shown in an ad. Confirm the license is active and check the agency license as well as the individual's where both exist.
- Agree on scope and cost in writing. Know what will be done, for how long, and what you'll receive.
- Share what you know. Names, addresses, photos, vehicles and schedules save billable hours.
- Insist on lawful methods. Maine generally allows a participant to record a conversation (one-party consent). Detectives shouldn't hack accounts, pretext for records, trespass or track phones.
What affects the cost of an investigation in Maine
Maine spans 16 counties. Surveillance in a dense area like Portland may call for two detectives to keep a subject in view, while work in rural counties can involve more travel time. Records research that requires courthouse visits in several counties takes longer than searches available online.
Most surveillance is billed hourly plus expenses such as mileage; defined research tasks are often flat-fee. Our cost guide explains pricing in detail.
