Due diligence data room checklist and index
A clear, numbered index saves time for everyone in a deal. Buyers find what they need, the seller sees what is missing, and questions refer to a document number rather than a vague description. This template gives you a standard 11-folder structure with the documents that usually go in each.
The folder structure
| Folder | What goes in it |
|---|---|
| 1. Corporate | Incorporation documents, articles, group chart, share register, minutes, shareholder agreements |
| 2. Financial | Audited accounts, management accounts, forecasts, debt schedule, working capital |
| 3. Tax | Returns, assessments, VAT or sales tax, withholding, disputes, transfer pricing |
| 4. Legal and contracts | Material contracts, change-of-control clauses, guarantees, litigation |
| 5. HR | Org chart, key contracts, incentive plans, end-of-service obligations, disputes |
| 6. Intellectual property | Trademarks, patents, domains, licences, IP assignments |
| 7. IT | Systems, licences, security policies, incidents, data protection |
| 8. Real estate | Property schedule, titles, leases, valuations |
| 9. Regulatory | Licences, regulator correspondence, AML and sanctions compliance |
| 10. Commercial | Business plan, revenue analysis, customer concentration, market, insurance |
| 11. ESG | Environmental, health and safety, sustainability and Shariah compliance |
How to use the index
- Number every document, for example 2.3 for the third item in the Financial folder. Keep the numbers stable once buyers have started reviewing.
- Add a folder or item only where it applies. Delete rows that do not apply rather than leaving empty folders.
- Use the Provided, Date uploaded and Owner columns to track progress with the client.
- Mark items that are withheld or redacted, and say why, in the Comments column.
Tips for the seller's adviser
- Start collecting documents before the process is announced. Gaps found late slow everything down.
- Put the most-requested documents first: audited accounts, management accounts and material contracts.
- Agree with the client who reviews each document before it goes in the room.
- Keep a log of who has seen what. Regulators, buyers and courts may ask later.
Adapting it for the region
For deals in Pakistan and the GCC, add items such as Islamic financing agreements, end-of-service benefit calculations, Shariah compliance documents and free-zone licences where relevant. The template already includes some of these.
