Company affidavit only or Full corporate document set — choosing the right route for intellectual property document certification
This page compares the two certification routes used for intellectual property document certification: when each applies, how many layers are involved, which authorities take part, what the translation must look like, and the mistakes that most often send a file back.
| Aspect | Company affidavit only | Full corporate document set |
|---|---|---|
| Scope | A single affidavit | Affidavit, memorandum of association, shareholder list, and board resolution |
| When it applies | The destination only needs proof of corporate existence | Setting up a subsidiary, opening a bank account, or bidding for work |
| Names and titles | Must match the registered filing | Must match across every document in the same set |
| Document age | Usually must be freshly issued within the destination's window | Every document should be issued in the same round |
| Risk | A later document request means a second certification round | Higher cost in one round, but fewer repeat filings |
| Common mistake | Using an English company name that differs from the registered one | A resolution signed by someone without authority under the affidavit |
How to choose
- If the destination is a bank or a registry, prepare the full set in the first round.
- Always verify signing authority in the affidavit before drafting the board resolution.
Documents to prepare
- Freshly issued company affidavit and certificate of registration
- Memorandum and articles of association, or the current shareholder list
- Board resolution or power of attorney signed by the authorised director
- ID or passport copies of the authorised signatories
- Registered English company name and job titles exactly as filed
- Counterparty or destination authority requirements for the certified set
