Structuring an Internal Investigation: from Allegation to Resolution


Internal investigations are a vital tool for managing risk, maintaining compliance, and protecting organizational integrity. At their core, these inquiries aim to uncover facts, assess legal exposure, and recommend corrective action. For corporate leaders, understanding the basic structure and purpose of an investigation is essential to handling it properly.

An internal investigation typically follows a structured lifecycle: intake, planning, fact-finding, analysis, and resolution. It begins with identifying the allegations and assessing their credibility and potential impact. The next step is developing an investigative plan, including defining the investigation’s scope, identifying key witnesses, and preserving relevant documents. The fact-finding phase requires collecting, searching, and reviewing relevant documents, either before or in tandem with interviewing witnesses. The final phase involves analyzing the evidence, making factual findings, determining what legal repercussions might result from those findings, and determining appropriate remedial actions or disclosures.

Our team works closely with executives and boards to demystify the process and help clients navigate complex issues with confidence and clarity.
