Growth Trends for Related Jobs


Oftentimes, investigators for law firms are retired police detectives with backgrounds in criminal investigation. However, some law firms are open to hiring private investigators who have passed the necessary courses and obtained a license. Although some states don't require investigators to be licensed, the majority do. If you wish to work as an investigator for criminal law attorneys, you'll need to have a solid grasp of criminal procedure, federal law and state law.

Enroll in a private investigator course in your area. Private investigator training involves study and testing on topics such as wiretapping statutes, criminal procedure, privacy law and other pertinent state and federal law. Some private investigator training schools specialize in litigation support with law firms as clients.

Complete the training, pass the test and obtain your license. Once you receive your license you can decide whether you want, or need, to obtain a concealed carry permit. Not all private investigators need to carry a handgun; however, many still do.

Network with the legal community. Once you're licensed, you'll need to meet attorneys in your area. Get in touch with specific practice departments in law firms you might be interested in working for. For example, if you want to perform litigation assistance for criminal cases, contact criminal law attorneys at several law firms in your location.


If you need to obtain a concealed weapons permit, your criminal record must be clear of any felonies.
