A legal investigation is the process by which a licensed private investigator gathers facts, locates witnesses, documents evidence, and conducts research in support of civil or criminal legal proceedings. The work is typically performed at the request of an attorney, a party to litigation, or an individual with a pending legal matter, and all methods used must comply with applicable state and federal laws.
A legal investigation means a private investigator is collecting information that may be used in court or to support a legal claim. This can include finding witnesses, verifying facts, or documenting events that are relevant to a case. The goal is to produce accurate, well-documented findings that an attorney or client can act on.
An attorney preparing for a civil lawsuit may hire an investigator to locate and interview witnesses before depositions are scheduled. A defendant in a criminal case may need an investigator to verify an alibi, identify surveillance footage, or find individuals who were present at the time of an incident. In family law matters, a party may request a legal investigation to document evidence of asset concealment or violations of a custody order.
Licensed private investigators can conduct surveillance in public spaces, locate witnesses through lawful database searches, obtain voluntary statements, and gather publicly available records. They cannot access sealed court records, private financial accounts, or law enforcement databases, and any evidence collected must be obtained through legal means to remain admissible. Requirements for investigator licensing and permissible methods vary by state, so investigators working across jurisdictions must comply with the laws of each applicable location.
What does the evidence collected during a legal investigation actually look like, and how is it delivered?
Investigators typically provide a written report summarizing their findings, supported by any relevant documentation such as photographs, video footage, interview summaries, or copies of public records. The format is often structured to be useful for attorney review or court presentation, but the investigator does not determine admissibility. That determination is made by the court based on how the evidence was obtained and how it is introduced.
Does a private investigator working on a legal matter coordinate directly with my attorney, or do I manage that relationship myself?
In most cases, the investigator can work directly with your attorney, and many attorneys prefer to retain investigators themselves so that communications may fall under attorney-client privilege protections. If you retain the investigator independently, you are responsible for sharing findings with your legal counsel. Either arrangement can work, but the structure should be established at the start of the engagement to avoid gaps in communication or documentation.
