Starting a company abroad can be an exciting way to expand a business, enter a new market, manage overseas property, work internationally or build a more global structure. However, company formation in another country often requires detailed paperwork, especially if the founders, directors or shareholders are based in the UK.
Foreign company registries, banks, lawyers, notaries and tax authorities may ask for UK-issued documents to prove your identity, address, business background, company ownership or authority to act. Some documents may need certification, apostille, translation or further legalisation before they are accepted.
Understanding what may be requested can help you prepare early and avoid delays with registration, banking and local compliance.
Why foreign registries ask for UK documents
When you start a company abroad, local authorities need to know who is behind the business. They may need to verify directors, shareholders, beneficial owners, company structure and the source of funds.
Documents may be required for:
- company incorporation
- tax registration
- opening a business bank account
- appointing directors
- proving shareholder ownership
- obtaining business licences
- signing notary documents
- registering a branch or subsidiary
- meeting anti-money laundering checks
- appointing a local representative
The exact requirements depend on the country, business activity and legal structure.
Passport and identity documents
Your passport is usually the main identity document when setting up a company abroad. Directors, shareholders and beneficial owners may each need to provide identification.
You may be asked for:
- passport copy
- certified passport copy
- proof of nationality
- driving licence copy
- national identity document, if applicable
- birth certificate, in some cases
- visa or residence permit, if required
A certified passport copy may need an apostille or translation depending on the country and authority requesting it.
Proof of address
Foreign registries, banks and notaries may ask directors or shareholders to prove their residential address.
Common UK proof of address documents include:
- utility bill
- council tax bill
- bank statement
- mortgage statement
- tenancy agreement
- HMRC letter
- driving licence
Many authorities require proof of address to be recent, often dated within the last three months. If a UK proof of address document is being used abroad, it may need certification or translation.
UK company documents
If you already own or represent a UK company, overseas authorities may ask for documents from Companies House or internal company records.
These may include:
- certificate of incorporation
- Companies House company profile
- articles of association
- memorandum of association
- confirmation statement
- register of directors
- register of shareholders
- persons with significant control information
- certificate of good standing
- board resolution
- company accounts
These documents may need to be certified, apostilled or translated before they are accepted abroad.
Certificate of incorporation
A certificate of incorporation confirms that a UK company has been legally registered. It is commonly requested when a UK business is setting up an overseas branch, subsidiary or bank account.
It may be used to prove:
- company name
- company number
- incorporation date
- legal existence
- registration in the UK
Foreign authorities may request an apostilled certificate of incorporation or a certified Companies House document.
Articles of association
Articles of association set out how a company is governed. They may be requested by foreign registries, banks, lawyers or notaries to understand the company’s internal rules.
They may be needed to confirm:
- director powers
- shareholder rights
- signing authority
- company structure
- decision-making rules
- share transfer rules
If submitted abroad, articles of association may need certification, apostille and translation.
Certificate of good standing
A certificate of good standing may be requested to show that a UK company exists and is up to date with filing obligations. It can be useful when opening a business bank account, registering a branch or entering into major contracts abroad.
It may confirm details such as:
- company name
- company number
- incorporation date
- active status
- filing compliance, where applicable
Some overseas authorities specifically ask for this document instead of ordinary Companies House records.
Board resolution
A board resolution may be needed when a UK company authorises an overseas transaction or appoints someone to act on its behalf.
It may approve:
- starting a company abroad
- opening a bank account
- appointing a local director
- appointing a representative
- signing a lease
- buying property
- investing funds
- granting power of attorney
A board resolution may need to be signed by the correct directors and may require certification, apostille or translation.
Power of attorney
A power of attorney is commonly used when forming a company abroad. It allows a lawyer, accountant, agent or local representative to act on your behalf.
It may be used to:
- submit company formation documents
- sign incorporation papers
- open bank accounts
- register for tax
- attend notary appointments
- collect official documents
- communicate with authorities
- sign contracts
A UK power of attorney for use abroad may need notarisation, apostille, translation or embassy legalisation.
Beneficial owner documents
Many countries require details of ultimate beneficial owners. This is part of anti-money laundering and transparency checks.
Documents may include:
- passport copies
- proof of address
- ownership chart
- shareholder register
- Companies House records
- trust documents, if applicable
- declaration of beneficial ownership
- source of funds documents
If the ownership structure is complex, a lawyer or accountant may need to prepare an explanatory statement.
Source of funds documents
Foreign banks and registries may ask where the money for the new company is coming from. This is especially common when opening a business bank account or making an investment.
You may need:
- bank statements
- savings statements
- sale agreement
- investment records
- dividend statements
- company accounts
- tax returns
- loan agreement
- accountant letter
- proof of inheritance, if relevant
Financial documents may need to be recent and may require certification or translation.
Tax documents
Tax registration is often part of starting a company abroad. Authorities may ask for UK tax documents for directors, shareholders or existing companies.
This may include:
- HMRC correspondence
- tax residency certificate
- self assessment records
- company tax documents
- VAT registration certificate
- national insurance confirmation
- tax identification details
- accountant letter
Tax residency can be complex when you operate across countries, so professional tax advice is recommended.
Bank documents
A business bank account is often needed after company formation. Banks usually have their own document requirements, which may be stricter than the company registry.
They may ask for:
- director passport copies
- shareholder passport copies
- proof of address
- company formation documents
- business plan
- source of funds evidence
- projected turnover
- contracts or invoices
- tax registration documents
- ownership structure chart
Some banks require documents to be certified, apostilled or translated.
Professional licences and permits
Some business activities require local licences before trading can begin.
This may apply to:
- financial services
- healthcare
- education
- construction
- recruitment
- transport
- food and hospitality
- property services
- legal or accounting services
- import and export
You may need UK qualifications, professional certificates, insurance documents or regulatory approvals as part of the licence application.
Name change or identity differences
If names do not match across documents, foreign authorities may ask for supporting evidence.
This can happen if:
- a director changed name after marriage
- passport and Companies House records differ
- shareholder records use initials
- proof of address uses a shortened name
- documents have spelling differences
- older certificates show a previous name
Supporting documents may include a marriage certificate, change of name deed, divorce document, birth certificate or statutory declaration. These may need apostille and translation.
Translation requirements
If the receiving country does not accept English documents, translations may be needed.
This may apply to:
- passport copies
- proof of address
- Companies House documents
- articles of association
- board resolutions
- powers of attorney
- bank statements
- tax documents
- professional certificates
Some authorities require certified or sworn translations. If a document has an apostille or legalisation stamp, that may also need to be translated.
Apostille for company formation documents
An apostille may be required when UK documents are submitted to foreign registries, banks, notaries or government authorities.
Documents that may need an apostille include:
- certified passport copy
- proof of address document, if properly certified
- certificate of incorporation
- Companies House documents
- articles of association
- certificate of good standing
- board resolution
- power of attorney
- tax document, if properly certified
- professional qualification
Not every document needs an apostille, but many overseas processes require legalised documents.
Embassy legalisation
Some countries require further embassy or consulate legalisation after the apostille. This is an additional step and may apply to company, legal or financial documents.
Embassy legalisation may be needed for:
- powers of attorney
- company certificates
- board resolutions
- director documents
- commercial agreements
- professional certificates
- tax documents
The order of legalisation matters, so check the destination country’s rules before preparing documents.
Common reasons company formation is delayed
Company formation abroad can be delayed when documents are missing, outdated or prepared incorrectly.
Common issues include:
- passport copy is not certified
- proof of address is too old
- company documents are not apostilled
- board resolution is not signed correctly
- power of attorney wording is not accepted
- source of funds evidence is incomplete
- ownership structure is unclear
- translations are missing
- embassy legalisation was required but not completed
- bank asks for extra documents after incorporation
Preparing both registry and bank documents early can reduce delays.
