Why Law Firms Work With Private Investigators

Law firms rely on accurate information to make sound legal decisions. Much of that information comes from documents, filings, and discovery. In many cases, however, key facts cannot be found in records alone.

This is where Birardi and Associates LLC provides support.

Private investigators are not part of a law firm’s internal staff. They are engaged when a case requires licensed fieldwork, independent fact checking, or information that cannot be gathered through desk research. Their work may involve locating people, confirming claims, uncovering information that was not disclosed, or documenting real-world behavior. Just as important, this work happens outside the firm, which helps limit risk to legal teams.

That separation becomes especially important when a case reaches the courtroom. When investigators testify, they do so as independent professionals rather than firm employees. This distinction allows investigators to explain how information was gathered, how evidence was handled, and what they observed without pulling the firm into questions about internal practices or staff involvement. Their testimony supports the facts presented while keeping clear boundaries between investigation and legal representation.

More broadly, this independence reflects the nature of investigative work itself. Law firms work with private investigators not because their staff lacks ability, but because investigation is a distinct line of work. It requires licensing, neutrality, field experience, and judgment developed through hands-on practice.

Legal staff manage cases from within the firm. Investigators extend the firm’s reach beyond it by finding people, verifying facts, documenting behavior, and uncovering information that does not surface through paperwork alone. When attorneys and investigators work alongside one another, firms gain reliable information without increasing staff burden or exposure. The result is stronger evidence, clearer decision-making, and better outcomes throughout litigation.
