These are people paid by private citizens and business organizations to gather facts about something that concern them. A private investigator is not a law enforcement officer thus, he does not have the power to arrest and prosecute people who committed crimes and other law violations.

They are also often hired to look for evidence of infidelity or any other activities that may be a ground for divorce.
Like many other professions, a private investigator can also choose a field of specialty. He can choose to be a legal investigator who specializes in court cases. Law firms usually hire a private investigator that can help them prepare their defenses in criminal cases, look for witnesses, serve or deliver legal documents, and review case evidences. Gathering information about litigation parties, taking photographs and testifying in courts are also included in the duties of a legal investigator. A private investigator may also choose to be a corporate investigator. This person is tasked to conduct internal and external investigations for corporations and business organizations. Internal investigations are those that investigate activities done within the organization and involving personalities within the group. External investigations, on the other hand, are those that involve inquiries about outsider activities and people not working within the corporation or business organization. Another specialty that a private investigator can choose is financial investigation. A financial investigator is hired to find out and evaluate the financial profile of individuals or companies that are about to go into financial transactions involving huge amounts of money. There are other specialties for private investigators to choose from depending on their experience and expertise.
