Michigan Private Investigator Licensing Law and Regulation

Domain 1: Michigan Private Investigator Licensing Law and Regulation

This section tests how Michigan licenses investigators, who may lawfully work, what conduct triggers discipline, and the penalties that follow violations. The named statute is the Private Security Business and Security Alarm Act, 1968 PA 330, MCL 338.1051 et seq.; licensing is administered by the Department of Licensing and Regulatory Affairs (LARA). Treat the current LARA application packet and administrative rules as controlling because fees, forms, and renewal dates change.

Core rules

  • A person may not engage in the business of private investigation for hire without the required state license; employees who perform investigative work must be licensed or qualify under a statutory exemption.
  • Common exemptions are narrow: attorneys practicing law, certain insurer employees, and public-agency personnel acting in official capacity. An exemption for one role does not create a general license for a side business.
  • Prohibited conduct includes unlicensed operation, false statements on an application, impersonating a peace officer, displaying badges or insignia that imply police authority, and failing to maintain required records.
  • Penalties can include criminal sanctions, license denial, suspension or revocation, and civil exposure. The exam often asks which sanction applies rather than the exact dollar amount.

Worked example

A client asks an unlicensed assistant to interview a witness and sign the report. The assistant may schedule appointments, but conducting the investigative interview and authorizing the report is licensed activity. The licensed investigator must personally supervise and sign, and should document the assistant's limited role. If the assistant holds out as an investigator, both the assistant and the licensee face exposure.

Traps

Do not assume a security-guard license authorizes investigative work. Do not use the title "detective" or a police-style badge to gain cooperation. Do not let a client's urgency override the licensing statute.
