What Is a Private Investigator?

A private investigator is someone who collects evidence about the subjects specified by their client. They often deal with civil, criminal, or business matters, conducting research, interviewing relevant contacts, compiling documents, and doing their own surveillance.

You might hire a private investigator if you get into a car accident, the other driver claims to be injured and sues you, and you suspect they’re faking it. Or a business may hire one to perform background checks on potential employees. There are many situations in which a private detective can help you.
