Foreign banks may ask for certified UK documents to confirm identity, address, tax status or source of funds. Learn why certification matters and how to prepare.

If you are opening a bank account abroad or dealing with a foreign bank, you may be asked to provide certified UK documents. This can include certified copies of your passport, proof of address, tax documents, company records or financial statements.

Certification helps the bank confirm that the document is genuine, complete and suitable for compliance checks.

What does “certified document” mean?

A certified document is usually a copy that has been checked against the original by an accepted professional. The certifier confirms that the copy is a true copy of the original, then signs, dates and adds their professional details.

For foreign banks, this can be important when you are not attending a branch in person or when documents are being submitted from another country.

Why banks do not always accept ordinary copies

A normal photocopy, scan or printed PDF may not be enough because the bank cannot easily confirm whether it is genuine. A copy could be incomplete, altered, outdated or taken from another copy.

Certification gives the bank extra assurance that the document has been checked properly.

Common reasons banks ask for certified UK documents

Foreign banks may ask for certified documents to confirm:

  • your identity
  • your residential address
  • your tax residency
  • your source of funds
  • your employment or income
  • your company ownership
  • your authority to act for a business or estate
  • your relationship to another account holder or beneficiary

The exact requirement depends on the bank, country and type of account.

Documents commonly requested by foreign banks

Foreign banks may request certified copies of:

  • passport
  • driving licence
  • proof of address
  • bank statements
  • utility bills
  • HMRC letters
  • tax residency documents
  • payslips
  • pension statements
  • company documents
  • probate documents
  • powers of attorney
  • source of funds evidence

Some banks may ask for specific wording on the certification, so it is important to check their instructions before arranging it.

Personal bank accounts

For personal accounts, certified documents are often used to confirm identity and address. A bank may ask for a certified passport copy, a certified proof of address document and sometimes tax residency evidence.

If you are opening the account remotely, certified documents are more likely to be requested because the bank cannot check your original documents in person.

Business bank accounts

Business accounts often require more paperwork. A foreign bank may ask for certified company documents as well as personal documents for directors, shareholders or authorised signatories.

This can include:

  • certificate of incorporation
  • Companies House documents
  • articles of association
  • director passport copies
  • shareholder information
  • proof of registered office
  • business tax documents
  • company bank statements

Some company documents may also need legalisation or certified translation before they are accepted.

Source of funds checks

Foreign banks may ask for certified evidence showing where money came from. This is common for larger deposits, property purchases, investment accounts or inheritance payments.

Source of funds documents may include bank statements, payslips, property sale records, inheritance documents, company accounts or tax records.

Does certification always need to be done by a notary?

Not always. Some banks accept certification by a solicitor, accountant, bank official or regulated professional. Others specifically ask for a notary.

The safest approach is to check the bank’s wording carefully. If the bank asks for a notarially certified copy, a normal solicitor certification may not be enough.

Do certified documents need legalisation?

Sometimes. Certification confirms that a copy matches the original. Legalisation confirms the signature, seal or stamp on the certified document.

Some foreign banks accept certified copies only. Others may ask for certified and legalised documents, especially for business, property, inheritance or high-value transactions.

Translation requirements

If the bank does not accept English documents, certified translations may be needed. This can apply to proof of address, bank statements, tax documents, company records and probate documents.

Check whether the translation should be completed before or after certification and legalisation.

Common mistakes to avoid

Certified documents can be delayed or rejected if:

  • the wrong person certifies the copy
  • the certification wording is incomplete
  • the certifier’s details are missing
  • the document is too old
  • the copy is unclear
  • pages are missing
  • names do not match
  • translation is required but not provided
  • legalisation is needed but not completed

Final thoughts

Foreign banks ask for certified UK documents because they need reliable evidence for identity, address, tax and compliance checks. A simple photocopy or scan may not provide enough assurance.
