Montana
Montana licenses private investigators through the Department of Labor and Industry’s Private Security Program. Since 2023 the Legislature abolished the Board of Private Security, the Department repealed investigator continuing education and cut fees to $80, a 2025 law added provisional licenses and tougher discipline, and a 2026 rule lists states treated as substantially equivalent.
At a glance
- Authority
- Department of Labor and Industry, Private Security Program (MCA 37-60-101, 37-60-202)
- Statute
- MCA Title 37, chapter 60, with the program licensing provisions in MCA 37-1 part 4
- Rules
- ARM 24.182
- Who is licensed
- Private investigators, PI trainees on a provisional permit, and armed endorsees (MCA 37-60-301; ARM 24.182.507, 24.182.512). Attorneys and those working under them, insurers, in-house investigators, and others are exempt (37-60-105).
- Qualifications
- At least 18, a high school education, and fingerprints for state and FBI checks (MCA 37-60-303).

A criminal conviction is not an automatic bar; the Department may deny if the offense relates to the occupation and, after investigation, it finds the applicant not sufficiently rehabilitated (MCA 37-1-203).
- Renewal
- Every year, by March 1 (ARM 24.101.413). $80 to apply and $80 to renew; armed endorsement $50 each (24.182.401). Late renewal adds a penalty equal to the renewal fee (24.101.403).
- Continuing education
- None since December 9, 2023
- Bond or insurance
- At least $500,000 in commercial general liability insurance including personal injury, plus firearms liability coverage if armed (ARM 24.182.405); no bond.
- Firearms
- An armed endorsement is required to carry a firearm on duty, with approved training and an annual proficiency test (MCA 37-60-301(3); ARM 24.182.420).
Changes, 2023 to 2026
Substantial equivalency list for out-of-state applicants
Implements HB 246 (Ch. 76, L. 2025, effective October 1, 2025) by incorporating the Department’s 2025 substantial equivalency list for the Private Security Program. Applications from people licensed in a listed state are treated as routine as to education, exam, and experience. The Department’s published determinations, an undated document, mark Louisiana, Nebraska, New Jersey, and New Mexico as substantially equivalent for private investigators.
For licensees: Fingerprints, insurance, and other Montana requirements still apply.
Investigator fees cut to $80; photo ID rule
Sets application and renewal fees at $80 for all license types (ARM 24.182.401); a private investigator previously paid $250 plus a $20 exam fee to apply and $175 to renew. The armed endorsement stays $50. Licensed investigators and supervised trainees already had to carry a photo ID card meeting the Department’s specifications; the amended rule (24.182.403) says “wear” in one paragraph and “wear or carry” in another, and the Department has said it will fix the wording.
For licensees: Carry a compliant photo ID while working.
Duty to report actions; fines up to $5,000; client confidences protected
Licensees must report actions bearing on their qualifications within 30 days of final disposition (MCA 37-1-150). The maximum fine for program licensees rises from $1,000 to $5,000 per violation (37-1-406), and revealing a client’s confidential information without consent becomes unprofessional conduct (37-1-410).
For licensees: Report qualifying actions within 30 days.
Provisional licenses for applicants still completing requirements
Allows a provisional license for an otherwise eligible applicant with pending conditions such as the exam or supervised experience (MCA 37-1-144), and lets a PI applicant who has not met the training and exam requirements apply for one (37-60-303(4)).
For licensees: The program’s rules still call this the PI trainee provisional permit.
Consumer Data Privacy Act thresholds lowered
The act now applies to businesses controlling or processing data of 25,000 or more consumers (down from 50,000), or 15,000 or more (down from 25,000) if over 25% of revenue comes from selling personal data (MCA 30-14-2803).
For licensees: More data vendors are covered.
Address duty moved; notices may be served electronically
Moves the existing duty to report address changes within 30 days into MCA 37-1-143 and adds a duty to keep an e-mail address current for licensees who consent to electronic service. Disciplinary notices may now be served electronically with consent, by certified mail to the most recent address, or in person, and the time to request a hearing becomes 21 days (37-1-403).
For licensees: A stale address can lead to a default decision.
Intimate image offenses extended to fabricated images
Extends MCA 45-8-213, which already barred publishing real intimate images to harass, to digitally fabricated images, to disclosures made to obtain money, and to threatening to disclose such images for money. The hidden-device recording offense, which requires the knowledge of all parties, is unchanged.
For licensees: Montana’s all-party rule for hidden recording is unchanged.
Contract clauses barring licensing complaints void
A contract provision that bars or discourages filing a licensing complaint is void, and being party to one or retaliating against a complainant is unprofessional conduct (MCA 37-1-149).
For licensees: Remove such language from client and employment agreements.
Consumer Data Privacy Act takes effect
Gives consumers rights of access, correction, deletion, and opt-out against covered businesses, enforced by the Attorney General. Processing to investigate, establish, exercise, prepare for, or defend legal claims is exempt.
For licensees: Most investigator firms fall below the thresholds; data vendors may not.
Rules overhauled; investigator continuing education repealed
Repeals the investigator continuing education rules (ARM 24.182.2101 to 24.182.2108) and inactive status, and keeps the 5,400-hour experience requirement with up to 2,700 hours from training or education.
For licensees: No continuing education is required.
Board of Private Security abolished
Repeals the Board of Private Security (MCA 2-15-1781, 37-60-201) and gives its authority to the Department of Labor and Industry, which now adopts and enforces the rules (37-60-202).
For licensees: Licenses, complaints, and rules are handled by Department staff.
Stalking: monitoring includes GPS devices
Provides that “monitors” in the stalking statute includes use of any electronic, digital, or global positioning device or similar technology (MCA 45-5-220(2)(b)).
For licensees: The stalking law has no investigator exemption.
Uniform penalties for unlicensed practice
Lets the Department issue cease-and-desist orders for unlicensed practice, with penalties up to $1,000 a day for violating one (MCA 37-1-109), and repeals the chapter’s own penalty section (37-60-411).
For licensees: Unlicensed investigative work faces daily penalties.
Checked and unchanged
- Licensed private investigative agencies remain permitted users of motor vehicle record personal information (MCA 61-11-509(7)).
- Montana has no standalone tracking device crime and no data broker registry law.
