Licensing

How Oregon Licenses Private Investigators

Oregon regulates private investigators under ORS 703.401 to 703.995, with administrative rules in OAR chapter 259, division 61. The program is run by the Department of Public Safety Standards and Training, known as DPSST. ORS 703.405 bars anyone from acting as an investigator, or claiming to be one, without a license issued under ORS 703.430, unless the law exempts them.

Oregon's license attaches to the individual investigator. DPSST also publishes a private investigator business listing, but the key check is the person who will do the work. A client can search that name in DPSST's IRIS records tool, confirm the license is active and call the program at its published number if anything is unclear.

Courts

How Oregon Courts Are Organized

Oregon's general jurisdiction trial court is the circuit court, a state court with a location in each of the 36 counties. Circuit judges are grouped into 27 judicial districts, so some districts cover more than one county. Circuit courts hear civil, criminal, family, juvenile, probate and small claims cases in most counties. In a few rural counties, the county court still handles some probate or juvenile matters. Justice and municipal courts take many traffic and minor cases.

How this service works

Investigator Consulting in Oregon

Delator Group is a private investigation firm licensed in Tennessee and headquartered in Nashville. In Oregon, Delator Group is not licensed as a private investigator or private investigative agency and does not perform, supervise or direct investigations. We review requests and refer them to independent investigators who hold the license Oregon requires. Those investigators contract with clients directly, set their own fees and are responsible for the work. Delator Group may receive compensation from participating investigators for referrals.

FAQ

Questions About Finding an Investigator in Oregon

Which Oregon communities have their own page?

Every incorporated Oregon city, town or village with more than 3,000 residents, plus every township or town government of that size, has its own page here, 100 in all. Smaller places are covered by the nearest page and the statewide guide.

Is Delator Group licensed in Oregon?

No. In Oregon, Delator Group provides investigator consulting and referral only. Investigations are performed by independently licensed Oregon investigators who contract with you directly.

Who licenses private investigators in Oregon?

The Oregon Department of Public Safety Standards and Training (DPSST), Private Investigator Program, under ORS 703.401 to 703.995 (license requirement in ORS 703.405); OAR chapter 259, division 61. Anyone who acts as an investigator, or represents that they are one, must hold an individual DPSST investigator license unless an exemption applies.

How do I check an investigator's Oregon license?

Search the investigator's name in DPSST's Private Investigator Information Records Inquiry System (IRIS) or call the program to confirm the license.

Is Oregon a one-party or two-party consent state?

Both, depending on the setting. Under ORS 165.540, a phone call can generally be recorded with one participant's consent, but an in-person conversation generally may not be recorded unless every participant is specifically informed. The exceptions are narrow, so check with an attorney before recording anyone in Oregon.
