Coverage Types for Private Investigators
These are the key insurance policies most relevant to your business type — ranked by importance.
Professional Liability (E&O)
RequiredCovers claims that your investigative services caused harm — incorrect identification of a surveillance subject, botched evidence gathering that damaged a legal case, privacy violations from improper investigative techniques, or negligent investigation that resulted in false accusations. PI professional liability covers your defense and any settlement.
General Liability
RequiredCovers third-party bodily injury and property damage. Required by state PI licensing boards in most states. PIs face GL exposure from surveillance activities — a subject who notices surveillance and is injured in a confrontation, property damage during an investigation, and liability arising from client-directed investigations.
Commercial Auto
RequiredPrivate investigators spend significant time in vehicles conducting mobile surveillance. Personal auto policies exclude business use and will deny claims if you are conducting surveillance for pay. Commercial auto is required for any vehicle used for investigative purposes — including your own personal vehicle used for surveillance work.
Cyber Liability
Highly RecommendedPIs gather and store sensitive personal information — subjects of investigation, client information, surveillance records, and legal documents. A data breach involving investigation files or client identity information is a significant legal and ethical exposure. Cyber liability covers breach notification costs and legal defense.
Errors & Omissions (E&O)
Highly RecommendedCovers claims from errors in your investigative reports — incorrect facts, misidentified individuals, or incomplete findings that damaged a legal case or client interest. Distinct from professional liability in some policies — verify your coverage addresses both service delivery claims and factual accuracy claims in your reports.

What You Need to Know
- →State PI licensing boards in most states require proof of GL and professional liability as a condition of licensing — no insurance, no license.
- →Misidentification of a surveillance subject is the highest-risk claim for PIs — following the wrong person and reporting incorrect findings can generate significant professional liability claims.
- →Privacy law violations — surveillance conducted in a manner that violates state privacy statutes or wiretapping laws — create both professional liability and personal criminal exposure.
- →Commercial auto is non-optional for PIs who conduct mobile surveillance — personal auto policies explicitly exclude business use.
- →Attorney clients are the most demanding PI clients — they will hold you to the highest evidentiary and factual accuracy standards, and will pursue liability claims for any investigative failures that damaged their case.
- →PI license bonds — separate from insurance — are required in some states as part of the licensing process.
What Does It Cost?
Solo private investigators pay $55–$90/month for GL and professional liability combined. PIs with employees, vehicles, and significant case volume pay $100–$160/month. Commercial auto for a vehicle used in surveillance adds $75–$150/month. State licensing requirements drive minimum coverage levels.
