FAQs

  • Introduction

    Some cases grow cold without ever getting solved by the police, and others tend to be too unorthodox for the police since they're mainly limited to criminal cases. This is where private investigators come in.

    Private investigators, also known as PIs, offer a wide range of services, including finding missing persons, tracking marital infidelity, investigating theft, running background checks, verifying insurance claims, and collecting debts on behalf of their clients.

    PIs work on any case requiring extensive research and investigation. Their duties range from gathering vital facts and connecting clues to providing conclusive information regarding the case.
  • What is a private investigator?

    Private investigators are experienced individuals hired to carry out detective work. They are fact-finding experts who dedicate time and effort to gather evidence and reveal information that would be difficult to gain through ordinary means. Private investigators can either operate alone or work for an agency.

  • Are private detectives real?

    Yes, private investigators are real. They provide their expertise to anyone who needs an in-depth investigation for an important matter. Whether tracking a long-lost loved one, running background checks, finding missing persons, or conducting general research, private detectives operate with discretion and rarely make the news.

  • What do private investigators do?

    PI work involves a lot of information gathering and fact analysis. Their field assignments involve carefully following persons of interest, conducting surveillance, interviewing people, and, sometimes, going undercover to get more information. They use GPS tracking devices, video recorders, computers, and other technology to collect information.

  • How do private investigators work?

    Private investigators’ ability to conduct examinations and close cases without their targets knowing their involvement makes them very effective. A PI firm may have different personnel, each specializing in a particular field. From computer experts to web-data analysts and field officers, these agents work together to solve cases or complete an objective.

  • What is a private investigator allowed to do?

    PIs are civilians, so they're required to operate within the confines of the law. Private investigators search multiple online databases, public records, and open source files to collect information. However, they cannot bug phones or hack into online accounts to acquire protected information. They can conduct surveillance on people in public places, but they can't trespass into their homes or property.
