M&A Due Diligence Checklist

This sample request letter and initial legal due diligence document checklist are directed to the domestic seller or target company in a merger and acquisition (M&A) transaction. The form below includes a general list of documents and information requested in many M&A transactions.

Keep in mind that some requests may not be necessary for every contract management workflow. For example, certain requests may apply only to a public or private company, and certain equity and property documents may not be relevant in an asset purchase. If a request is broader than needed for the purposes of due diligence, it may be useful to limit the scope of the request. In some cases, the five-year limitation may be sufficient. In other cases, limitations such as the materiality standard may be appropriate.
