Frequently asked questions
What if a subject claims I was stalking them?
Stalking and harassment allegations are among the most serious claims for PIs. Professional liability insurance covers your legal defense even when investigations were lawfully conducted.
Do private investigators need to be licensed?
Most states require PI licensing. Many states require proof of liability insurance as a condition of obtaining or renewing a PI license.
Am I covered for surveillance conducted in public?
Lawful public surveillance is covered. Activities that cross into illegal surveillance — entering private property without permission, illegal wiretapping — are typically not covered and can void your policy.
How to get the best rate
The fastest way to find the lowest rate is to compare multiple carriers side by side. Most private investigators can get quotes from 3–5 insurers in under 10 minutes and receive their certificate of insurance the same day.
