How to Hire a Private Detective in North Dakota

North Dakota licensing at a glance

North Dakota licenses private detectives through the Private Investigative and Security Board.

Step by step: hiring in North Dakota

1. Define your question. What do you need to know, and what decision depends on it?
2. Verify licensing. Look the detective up on the North Dakota Private Investigative and Security Board 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.
3. Agree on scope and cost in writing. Know what will be done, for how long, and what you'll receive.
4. Share what you know. Names, addresses, photos, vehicles and schedules save billable hours.
5. Insist on lawful methods. North Dakota generally allows a participant to record a conversation (one-party consent), unless it's done with criminal or tortious intent. Detectives shouldn't hack accounts, pretext for records, trespass or track phones.

What affects the cost of an investigation in North Dakota

North Dakota spans 53 counties. Surveillance in a dense area like Fargo 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.
