It is important you perform your due diligence before hiring a company. You should do the following: ask for and check references, obtain their license number and check with the state licensing board to make sure they are current and have no complaints. It may also be a good idea to check for complaints with the local Better Business Bureau.

When contacting an investigator, if discretion is important, you should make sure that you are not using an email or a phone number that you share with others. Additionally, if you are emailing or leaving a voice-mail you should give explicit instructions as to when you would like your message returned.

Law firms, corporations, insurance companies, private parties and entities not involved with the government or police all have reasons to procure the services of a private investigator.

A private investigator — also known as a PI, Private Detective or Private Eye — is someone that is hired to undertake an investigation. Most states require PIs to be trained and licensed. Investigators often have a law enforcement and/or a military background.
