Expanding a UK company overseas can open new opportunities, but it usually involves formal paperwork. Foreign banks, regulators, lawyers, tax authorities, commercial partners and government bodies may ask for UK company documents before they will register the business, open accounts or approve transactions.
The documents may be valid in the UK, but they may still need certification, legalisation, translation or embassy attestation before they can be accepted abroad.
Company registration documents
Most overseas authorities will ask for proof that the UK company exists and is properly registered.
This may include a Certificate of Incorporation, Companies House company profile, company extract, Memorandum and Articles of Association or other official company records.
Some Companies House documents can be legalised in official format. Downloaded PDFs or printed versions may need solicitor or notary certification before they can be used overseas.
Certificate of Good Standing
A Certificate of Good Standing may be requested to confirm that the company is active, compliant and properly registered.
This document is often requested by overseas banks, regulators, tender authorities and commercial partners.
It may need to be recently issued. If the certificate is electronic or printed without a verifiable signature, seal or stamp, solicitor or notary certification may be required before legalisation.
Director and shareholder documents
Foreign authorities may ask for evidence of who owns, controls and manages the UK company.
This can include director appointment documents, shareholder registers, share certificates, PSC information, ownership structure charts or board records.
Because many of these are internal company documents, they often need solicitor or notary certification before legalisation.
Board resolutions and authority letters
If someone is authorised to open a bank account, sign contracts, appoint a local agent or register the company overseas, a board resolution may be required.
The resolution should clearly state who is authorised to act and what powers they have.
As an internal company document, it usually needs solicitor or notary certification before it can be legalised for overseas use.
Power of Attorney
A Power of Attorney is often needed when a lawyer, accountant, agent or director will act for the UK company abroad.
This may be used for company registration, bank account opening, property transactions, tax matters or contract signing.
Some countries accept solicitor-certified Powers of Attorney, while others specifically require notarisation by a Notary Public. The receiving authority’s wording should be checked carefully before signing.
Financial and tax documents
Overseas banks, regulators and business partners may ask for financial evidence or tax documents.
This can include bank statements, audited accounts, accountant letters, HMRC letters, VAT certificates, tax residency certificates or proof of source of funds.
Many of these documents are issued digitally, so they may need certification before legalisation.
Commercial contracts and agreements
If the company is entering into overseas contracts, the counterparty may ask for signed agreements, distributor contracts, supplier agreements or service contracts to be legalised.
Private contracts usually need solicitor or notary certification before legalisation.
Check whether the receiving party needs the full contract, a certified extract or a specific signing authority document.
Translation and embassy attestation
If the destination country does not accept English documents, certified or sworn translation may be required.
For countries outside the Hague Apostille Convention, UK legalisation may not be the final step. Embassy or consular attestation may also be required before company documents are accepted.
This should be confirmed early, especially if the expansion involves licensing, banking or regulatory deadlines.
Prepare a complete company document pack
Before expanding overseas, ask the foreign bank, lawyer, regulator or partner for a written checklist.
Confirm which documents are required, whether originals or certified copies are accepted, whether notarisation is needed, and whether legalisation, translation or embassy attestation applies.
