Corporate, 2. Financial …) and every document keeps its number (1.1, 1.2 …) from the first request list to closing. Start with the list for your deal type, mark items that do not exist as "not applicable" rather than deleting them, and add the specialist lists your counterparty's advisers will work through – a company sale usually combines the M&A, legal, financial and tax checklists. When the list is agreed, set up the data room with the same structure, open it only after an NDA is signed and give each bidder or investor access to the folders they need.
