What is a private investigator?
While each state has its own definition of a private investigator, in general, a private investigator is someone who is hired for a fee or other consideration to obtain information regarding the habits, conduct, whereabouts, or trustworthiness of people; the location of stolen property; and/or the cause or responsibility of accidents, injuries, or fires. Private investigators can also be tasked to secure evidence for use in a court proceeding or other hearing.
What is required to become a private investigator?
Laws vary by state, ranging from zero years of experience up to six years/10,000 hours of experience. Of the states that require a private investigator to have a license, ten states have absolutely no requirements regarding previous experience, while other states, such as Nevada, require 10,000 hours of experience. Another example is Maine, which requires six years of experience. In most states, at least two years of related experience is required before obtaining a license.
