Private investigation involves the process of gathering information and evidence to solve cases or uncover facts. Private investigators, often referred to as PIs, are hired by individuals, businesses, or attorneys to conduct investigations on various matters, such as infidelity, fraud, or missing persons. They use various techniques, including surveillance, interviews, and background checks, to obtain the necessary information. The work of a private investigator is typically legal and regulated, requiring licenses in many jurisdictions. PIs must adhere to laws and ethical guidelines while conducting their investigations. Their findings can be used in legal proceedings or to help clients make informed decisions about personal or professional matters.
