While not statutorily required by Tennessee for private investigators, general liability insurance is strongly recommended and often contractually required by clients or property owners. No state mandate exists for this coverage type.

Tennessee does not currently mandate E&O insurance for licensed private investigators. However, it is considered a best practice due to the nature of investigative services involving data collection, surveillance, and potential defamation or privacy claims.
