Need to use a UK certificate of incorporation overseas? Learn when it may be requested, what it proves, and whether certification, translation or legalisation may be required.

A UK certificate of incorporation may be needed when a company has to prove its legal existence overseas. It is commonly requested by foreign banks, lawyers, notaries, government bodies, business partners and tender authorities.

Before sending the document abroad, check whether a standard copy is enough or whether the receiving authority needs a certified, legalised, translated or embassy-attested version.

What is a certificate of incorporation?

A certificate of incorporation confirms that a UK company has been officially formed. It normally shows key company details such as:

• Company name
• Company number
• Date of incorporation
• Company type
• Jurisdiction of registration
• Issuing authority details

Overseas authorities may use it to confirm that the company exists and is registered in the UK.

When it may be needed overseas

A certificate of incorporation may be requested for:

• Opening a foreign bank account
• Registering a branch abroad
• Setting up a subsidiary
• Signing overseas contracts
• Applying for tenders
• Appointing a distributor or agent
• Buying property abroad
• Registering for tax overseas
• Applying for licences or permits
• Proving company ownership or structure

It is often submitted with other company documents.

Check whether a standard copy is enough

Some authorities may accept a basic copy or download. Others may require an official certified version.

Ask whether they need:

• Standard certificate
• Companies House certified document
• Solicitor-certified copy
• Notarised copy
• Legalised certificate
• Embassy-attested certificate
• Certified translation

Do not assume a downloaded copy will be accepted for official overseas use.

Certified Companies House document

Some foreign authorities ask for a certified document from Companies House. This may provide more assurance than a simple copy.

Check whether the receiving authority wants:

• Certified certificate of incorporation
• Certified company profile
• Certified current appointments report
• Certified articles of association
• Certificate of good standing, if available or requested

The requested document should match the authority’s wording.

Solicitor or notary certification

If the certificate is not accepted as a basic copy, it may need to be certified by a solicitor or notary. This can help confirm that the copy matches the original or that the document has been checked.

Ask whether the authority requires:

• Solicitor certification
• Notary certification
• Certification wording in a specific format
• Wet signature
• Professional stamp
• Legalisation after certification

For some countries, notary certification may be preferred for business documents.

Legalisation requirements

A certificate of incorporation may need legalisation before it is accepted overseas. Legalisation confirms the authenticity of the signature, stamp or seal on the document or certification.

Before arranging legalisation, check whether the authority wants:

• Certified Companies House document legalised
• Solicitor-certified copy legalised
• Notarised copy legalised
• Original certificate legalised, if suitable
• Translation after legalisation

Legalising the wrong version can cause rejection.

Embassy attestation

For some countries, UK legalisation may not be the final step. Embassy or consular attestation may also be required.

This may apply when the certificate is used for:

• Branch registration
• Business licensing
• Foreign bank accounts
• Commercial contracts
• Tenders
• Distributor agreements
• Property transactions
• Government filings

Ask the overseas authority whether embassy attestation is required before submission.

Translation requirements

If the receiving authority does not accept English documents, the certificate may need certified or sworn translation.

Ask:

• Which language is required?
• Is certified translation accepted?
• Is sworn translation required?
• Should translation happen before or after legalisation?
• Should the legalisation certificate be translated?
• Must the translator be locally approved?
• Should company names and numbers remain unchanged?

Company names and registration numbers should be handled consistently in translation.

Documents often requested with it

A certificate of incorporation is often only one part of the company document pack.

You may also need:

• Articles of association
• Current appointments report
• Confirmation statement
• Shareholder details
• PSC information
• Board resolution
• Power of attorney
• Director passport copies
• Proof of business address
• Tax documents
• Company accounts

Check whether each document also needs certification, translation or legalisation.

Check company name and number

Before sending the certificate overseas, check that the company details match all other documents.

Compare:

• Company name
• Company number
• Registered office address
• Director names
• Shareholder details
• Contract name
• Bank application name
• Power of attorney
• Translation

Even small differences can cause questions.

Check whether recent company evidence is needed

A certificate of incorporation proves the company was formed, but it does not always prove the company is currently active.

Some authorities may also ask for:

• Certificate of good standing
• Current appointments report
• Recent confirmation statement
• Company profile
• Recent Companies House extract
• Accountant letter
• Tax registration document

Ask whether current status evidence is required.

Business bank account use

Foreign banks often ask for a certificate of incorporation when opening an account for a UK company.

They may also ask for:

• Articles of association
• Director passport copies
• Shareholder details
• PSC details
• Board resolution
• Proof of trading activity
• Proof of registered office
• Tax residency information
• Source of funds evidence

Banks may have stricter requirements than other authorities.

Branch or subsidiary registration

If the certificate is being used to register a branch or subsidiary abroad, the authority may need a larger document pack.

This may include:

• Certificate of incorporation
• Articles of association
• Company status evidence
• Director and shareholder documents
• Board resolution
• Power of attorney
• Translation
• Legalisation
• Embassy attestation

Ask for the full registration checklist before preparing documents.

Checklist before using a certificate of incorporation overseas

Before submitting the document, check:

• Is a certificate of incorporation required?
• Is a standard copy accepted?
• Is a certified Companies House document needed?
• Is solicitor or notary certification required?
• Does it need legalisation?
• Does it need embassy attestation?
• Does it need translation?
• Are other company documents needed?
• Do company details match across all documents?
• Is current company status evidence also required?

Common mistakes to avoid

Avoid these mistakes when preparing a certificate of incorporation for overseas use:

• Sending a basic download when certification is required
• Forgetting legalisation
• Missing embassy attestation
• Translating before checking legalisation requirements
• Using outdated company details
• Forgetting articles of association
• Not including director or shareholder evidence
• Legalising the wrong version
• Sending unclear scans
• Assuming a certificate of incorporation proves current company status

Final thoughts

A UK certificate of incorporation is often used overseas to prove that a company exists, but it may need extra preparation before it is accepted. Depending on the authority, this can include certification, notarisation, legalisation, embassy attestation or translation.

Before submitting, confirm the exact document format and check whether additional company records are needed. Preparing the certificate correctly can help avoid delays with overseas banking, contracts, tenders or company registration.
