Understanding M&A Due Diligence

M&A due diligence is the investigative process that occurs between signing a letter of intent and closing a transaction. For legal professionals, this process involves reviewing thousands of documents, identifying risks, and advising clients on deal structure and protections.

The scope of legal due diligence has expanded significantly in recent years. Beyond traditional contract review, attorneys now must consider data privacy compliance, cybersecurity risks, ESG factors, and complex regulatory requirements. This evolution has increased both the volume and complexity of due diligence work.

Modern due diligence combines traditional legal analysis with technology-enabled workflows. AI-powered tools can automate first-pass document review, extract key terms, and identify potential issues, allowing attorneys to focus on substantive legal analysis and strategic advice.
