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.

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.

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.

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.
