A UK Certificate of Incorporation may be needed when a company is doing business abroad. It can be requested by foreign banks, government authorities, business partners, notaries, regulators or company registries.
If the document is being used outside the UK, it may need to be legalised with an apostille before it can be accepted. An apostille helps confirm that the UK company document is genuine or that the recognised signature, stamp or seal attached to it can be verified for international use.
The correct process depends on the type of Certificate of Incorporation you have and what the overseas authority requires.
What is a Certificate of Incorporation?
A Certificate of Incorporation is an official document confirming that a company has been incorporated and registered. It usually includes the company name, company number, date of incorporation and company type.
For UK limited companies, this document is issued through Companies House.
Foreign authorities may ask for it as proof that the company legally exists in the UK.
Can a UK Certificate of Incorporation be apostilled?
Yes. A UK Certificate of Incorporation can usually be apostilled, but the document format matters.
Some official Companies House documents may be suitable for apostille if they contain the correct authentication. In other cases, a certified copy or solicitor-certified version may be required before the apostille can be added.
The apostille confirms the authenticity of the recognised signature, stamp or seal. It does not confirm the company’s trading activity, financial status or commercial reputation.
When might you need a Certificate of Incorporation apostille?
You may need an apostilled Certificate of Incorporation for:
- opening a foreign business bank account
- registering a branch or subsidiary abroad
- entering overseas contracts
- applying for licences or permits
- appointing overseas representatives
- setting up with foreign suppliers
- buying property through a UK company
- tax registration abroad
- tender applications
- compliance checks by foreign authorities
The exact requirement depends on the country, bank, regulator or business partner requesting the document.
Companies House document or certified copy?
A Companies House document may be issued or downloaded in different formats. A simple downloaded PDF may not always be enough for apostille or overseas use.
Some authorities may ask for a certified Companies House document. Others may accept a solicitor-certified copy or a document certified by another authorised professional.
Before arranging legalisation, check whether the receiving authority requires an official Companies House certified document, a solicitor-certified copy or another format.
Why certification may be needed
A Certificate of Incorporation may need certification if the document does not contain a directly verifiable signature, stamp or seal.
A solicitor or notary can certify a copy of the company document. The apostille can then be attached to that certification.
For corporate documents, foreign banks and authorities may be strict about the format. If the certification is missing, unclear or not accepted by the receiving authority, the document may be rejected.
Do you need other company documents as well?
A Certificate of Incorporation is often only one part of an overseas corporate document pack.
You may also be asked for:
- Memorandum and Articles of Association
- Certificate of Good Standing
- Companies House company profile
- register of directors
- register of shareholders
- board resolution
- shareholder resolution
- company power of attorney
- proof of registered office
- tax or VAT documents
Each document may need to be certified and apostilled separately.
Does the document need to be recent?
The Certificate of Incorporation itself shows the date the company was created, so it does not usually become outdated in the same way as a company status document.
However, some foreign banks or authorities may ask for recently issued company documents or a recent Companies House certified copy. They may also request a Certificate of Good Standing to confirm the company’s current status.
If the requirement mentions a recent document, check whether the Certificate of Incorporation alone is enough.
Do you need a translation?
If the Certificate of Incorporation is being used in a country where English is not accepted, a certified translation may be required.
The correct order can vary. Some authorities want the document apostilled first and then translated. Others may ask for the translation to be certified or legalised as well.
This is common for corporate registration, banking, notarial and government procedures abroad.
Will an apostille be enough?
In many countries, an apostille is enough for a UK Certificate of Incorporation to be accepted. However, some countries may require further embassy or consular legalisation after the apostille.
This depends on the destination country and the organisation requesting the document.
Before submitting company documents abroad, check whether an apostille alone is sufficient.
Common reasons for delays
A Certificate of Incorporation apostille application may be delayed if the document is only a basic downloaded PDF, if the certification is incomplete, or if the solicitor or notary details are unclear.
There may also be delays if the receiving authority requested a different company document, such as a Certificate of Good Standing, company profile or board resolution.
Checking the exact corporate document requirement before legalisation can help avoid rejection.

Final checklist
Before arranging an apostille for a UK Certificate of Incorporation, check whether the receiving authority requires an official Companies House document, a certified copy or a notarised version.
You should also check whether other company documents are needed, whether a translation is required and whether the destination country accepts an apostille only or asks for further legalisation.
Preparing the company document correctly from the start can help avoid delays with overseas banking, registration, contracts or business procedures.
