Apostille for Company Documents: What UK Businesses Need to Know in 2026

When a UK company sends a document overseas, the receiving authority may need proof that the signature, seal or stamp on that document is genuine. An Apostille is the UK government's standard certificate for this purpose. The Foreign, Commonwealth & Development Office (FCDO) checks the signature, seal or stamp against its records and, where the requirements are met, attaches an Apostille. It does not certify that the commercial terms inside a contract are true or fair.

For a business, that distinction matters. A foreign bank may ask for a certificate of incorporation. A new overseas subsidiary may need a board resolution or Power of Attorney. A tax authority may ask for proof of UK residence. The document, its certification, the Apostille route and the rules of the destination country all need to line up.

We have written this article for company directors, finance teams, company secretaries, legal advisers and founders who need a clear route through the process in 2026. The exact requirement can vary by document and destination, so the safest approach is to confirm the receiving authority's instructions before execution.

What Does an Apostille Actually Do?

An Apostille is a certificate issued by the FCDO Legalisation Office. Its purpose is narrow but important: it confirms that a signature, seal or stamp on a UK document matches the specimen held by the Legalisation Office. Once legalised, the document can be presented abroad where the destination accepts the Apostille system.

It is not a second form of corporate due diligence. The FCDO does not read your agreement and decide whether its business terms are correct. Nor does an Apostille prove that a director had commercial authority simply because a document has been apostilled. Where the underlying document is private, the notarial or solicitor certification before FCDO submission is often the key bridge between the company's paperwork and the government authentication stage.

This is why a request for an 'apostilled company document' should never be treated as a single rubber-stamp task. There is usually a document stage, a certification stage, an FCDO stage and, in some countries, a consular stage.

Which Company Documents May Need Legalisation?

The right route depends on what the document is, who issued or signed it, and what the overseas recipient has requested. Common business documents include the following.

Document type	Typical business use	Possible preparation route
Certificate of Incorporation	Proof of company existence for overseas registration or banking	Companies House certified document or other acceptable official document
Certified company records	Due diligence, branch registration, banking and compliance	Companies House certified copy or certificate
Certificate or statement of good standing	Evidence of current corporate status	Obtain the appropriate Companies House certificate or certified information
Board resolution	Evidence that directors approved a transaction	Execution or certification by a UK notary or solicitor where required
Power of Attorney	Authorising an overseas agent, lawyer or director	Notarial execution or certification may be required
Commercial contract	Cross-border trading, supply or joint venture work	Certification depends on the recipient and document
HMRC tax residence certificate	Tax treaty and overseas compliance matters	Obtain the relevant HMRC certificate, then check legalisation requirements
Intellectual property documents	Overseas filings, assignments and registrations	Follow the receiving registry's exact certification rules

Companies House confirms that company certificates and certified copies can be legalised by the FCDO, provided the document carries the required original signature of a British public official. Companies House also provides certified documents and certificates that can be ordered for legalisation.

The First Question Is Not 'Where Is the Apostille Office?'

The first question is: what exactly has the overseas recipient asked for?

This sounds obvious. It is where many avoidable delays begin. One bank may accept an e-Apostille. Another may insist on paper. One overseas registry may ask for a certified copy of a Companies House document. Another may require a notarial certificate confirming corporate authority. Some destinations also require further embassy or consular legalisation.

Before we arrange the certification, we want to know:

·         Which country will receive the document?

·         Which authority, bank, registry or lawyer is asking for it?

·         Do they require the original, a certified copy or a notarial act?

·         Do they accept an e-Apostille?

·         Do they require translation?

·         Will the document need embassy or consular legalisation after the FCDO stage?

·         Is there a signing or closing date that affects the timetable?

This recipient-led approach is more reliable than choosing a legalisation route first and hoping the overseas authority accepts it later.

Paper Apostille or E-Apostille?

The FCDO currently offers both paper-based Apostilles and e-Apostilles. GOV.UK states that applications for both are made online. A paper Apostille involves the physical document, while an e-Apostille is issued as a digitally signed PDF after the document has been electronically signed by an eligible UK notary or solicitor.

Route	Current FCDO position	When it may suit a business
Standard paper Apostille	Usually up to 25 working days, plus delivery time	When the recipient needs paper or the document is not eligible for an e-Apostille
Next-Day paper service	Next working day for registered businesses	Urgent corporate work where the service requirements are met
Restricted Urgent paper service	Same day for registered businesses, with pre-approval	Very time-sensitive transactions
e-Apostille	Up to 2 working days	Where the recipient accepts a digital document and the document qualifies

The FCDO's published fees currently list £45 for standard paper legalisation, £40 for the Next-Day registered-business service, £35 for an e-Apostille and £100 for the Restricted Urgent service. These are government fees per document and do not include professional preparation, notarial work, courier charges or any embassy fees that may follow.

Times are not promises of acceptance. The Legalisation Office notes that processing can take longer if a signature needs verification.

What Is the Difference Between Notarisation and Apostille?

This is one of the most important points for corporate teams.

A notary can authenticate an act, certify a copy, witness a signature and record relevant facts about identity or corporate authority, depending on the matter. The FCDO then checks the notary's signature, seal or stamp. In simple terms, the notary creates the professional certification that the FCDO can verify; the Apostille is the government's authentication of that certification.

For private corporate documents, this often means a director attends a Notary Central London appointment with the relevant corporate records and identification. The notary considers the execution and certification requirements, prepares the notarial act where appropriate, and the document can then move to the FCDO route.

The precise steps depend on the document. A board resolution, Power of Attorney and certified copy of a passport do not necessarily follow identical procedures.

Companies House Documents: A Common Corporate Route

Companies House is especially relevant to international business because its certified documents are public-registry records. GOV.UK confirms that certified company documents and certificates can be ordered and then legalised by the FCDO. Companies House also offers express dispatch for certain orders, subject to its stated conditions.

A company expanding abroad may therefore need to coordinate two separate government processes: first obtaining the correct certified Companies House document, then having it legalised by the FCDO.

For example, if an overseas bank asks for current evidence of incorporation and company status, a generic PDF downloaded from the Companies House website may not be the document it wants. The bank may ask for a certified certificate or other specified document. That small distinction can matter.

We therefore recommend treating the overseas request as the controlling document specification, rather than assuming that every Companies House record is interchangeable.

Private Corporate Documents Need More Care

Board resolutions, Powers of Attorney and commercial agreements are not the same as public registry certificates. They are often created inside the business and signed by directors or other authorised people.

The receiving authority may want evidence that the signatory had authority to bind the company. It may also require a notarial certificate, certified copy, particular wording or a prescribed form.

For a corporate appointment, we may need to review documents such as:

·         The company's current constitutional documents

·         Board minutes or a resolution approving the transaction

·         Evidence of the signatory's identity

·         Companies House information

·         The overseas authority's signing instructions

·         Any prescribed wording supplied by foreign counsel or a bank

The point is not to create paperwork for its own sake. It is to build a clean evidential chain that a foreign recipient can understand and verify.

When Does Embassy Legalisation Come After the Apostille?

An Apostille is designed for countries that accept the Hague Apostille Convention. Where the destination does not use that system, further legalisation may be needed. GOV.UK explains that, for a non-Hague destination, the process can involve FCDO legalisation followed by the destination country's embassy or consulate and then, in some cases, approval by the relevant authority in the destination country.

That means 'Apostille complete' does not always mean 'ready for use abroad'. The final destination rules matter.

For a company with a fixed overseas closing date, this distinction is crucial. A document may need to pass through London legalisation and then a foreign mission before it reaches the receiving registry. Translation can also add another stage.

A Practical Corporate Workflow for 2026

We approach corporate legalisation as a chain rather than a single event.

Stage	What happens	Business risk if missed
1. Destination check	Confirm recipient, country and required format	Wrong route or rejected document
2. Document check	Identify original, certified copy or private document	FCDO cannot process unsuitable paperwork
3. Corporate authority	Confirm who can sign and under what authority	Execution may be challenged abroad
4. Notarial or solicitor certification	Create the required UK professional certification	No verifiable signature or seal
5. FCDO application	Apply for paper Apostille or e-Apostille	Processing delay
6. Consular stage	Complete embassy legalisation if required	Document still not accepted overseas
7. Delivery	Send the finalised documents securely	Closing or onboarding delay

This sequence is deliberately simple. International paperwork becomes much easier to manage when every stage has an owner and the final recipient's instructions are written down before anyone signs.

Common Corporate Problems We See

The wrong version of a document

A company may have five versions of a board resolution in circulation. Only one may match the final transaction. Apostilling the wrong version does not solve the underlying problem.

A document is signed before the required wording is agreed

Some overseas authorities prescribe wording, signing blocks or certification language. Signing first and asking questions later can mean starting again.

Digital is assumed to be acceptable

An e-Apostille is not automatically accepted by every recipient. The receiving bank, registry or lawyer should confirm acceptance before a company chooses the digital route. GOV.UK expressly advises applicants to check whether a paper-based Apostille is required.

The company needs more than an Apostille

Apostille, translation, embassy legalisation and local filing are separate requirements. A business should budget time for the whole chain, not just the FCDO certificate.

Why Central London Can Matter for Urgent Corporate Work

For directors and legal teams working around Holborn, Chancery Lane, Bank, St Paul's, Farringdon and Soho, proximity can make a practical difference when a document needs to be signed, certified and moved quickly.

At Staple Inn Notaries, we work with corporate clients who may be balancing a board meeting, a bank onboarding request and an overseas closing date on the same day. Our role is to make the document pathway clear, check the intended use and complete the notarial stage correctly before the paperwork moves into legalisation.

Our main Central London location is at Fox Court, 14 Gray's Inn Road, Holborn, London WC1X 8HN. We also work with clients around the City and other Central London business districts, including Bank, St Paul's, Farringdon and Soho, with mobile appointments available where appropriate.

For clients searching for Apostille Central London services, the useful question is not simply how quickly a certificate can be attached. It is whether the final document will meet the overseas recipient's rules.

Our Corporate Apostille Service

We support UK businesses that need documents prepared for use outside the UK. Depending on the matter, this can include:

·         Corporate document review before signing

·         Notarial witnessing and certification

·         Certified copies of corporate and identity documents

·         FCDO Apostille coordination

·         Paper and e-Apostille pathway planning

·         Embassy and consular legalisation coordination where required

·         Mobile notary appointments for directors and executives

·         Support with urgent Central London document workflows

Our work is focused on reducing avoidable rejection. We do not treat every document as though it follows the same template. The destination, recipient and document type drive the process.

The Wider Private Client Connection

The same international authentication issues can arise outside corporate work. Families with overseas property, trusts, inheritance matters or powers of attorney may also need UK documents prepared for use abroad. A Wills and Probate Lawyer London search, for example, may lead to a separate need for notarial or Apostille services where an estate has assets or beneficiaries in another jurisdiction.

That does not make an Apostille a substitute for private client legal advice. It simply shows why legal planning and document authentication can overlap in international families.

Conclusion: Build the Legalisation Chain Before the Deadline

For UK businesses, an Apostille is a small certificate with a large practical purpose. It can help a foreign authority trust the authenticity of a UK signature, seal or stamp. But the Apostille is only one part of the journey.

The strongest corporate process starts with the overseas recipient. Confirm the document. Confirm the format. Confirm whether certification, Apostille, translation or embassy legalisation is required. Then arrange the signing and authentication in the right order.

We help businesses across Central London put that sequence into practice. From a board resolution in Holborn to a Power of Attorney for an overseas bank, the aim is the same: a clear, defensible document trail that is ready for the authority that will receive it.

If your company has an overseas transaction approaching and you are unsure whether you need notarisation, an Apostille or further legalisation, contact Staple Inn Notaries before the document is signed. Early checking is often the simplest way to protect a closing date.

Frequently Asked Questions

Does every company document need an Apostille?

No. The requirement depends on the destination country, document type and the instructions of the overseas recipient.

Can a Companies House certificate be apostilled?

Yes, eligible Companies House certificates and certified documents can be submitted for FCDO legalisation, subject to the applicable requirements.

Is an e-Apostille always accepted overseas?

No. The receiving authority must accept the digital format, and some documents are not eligible for an e-Apostille.

How long does an Apostille take in 2026?

The FCDO currently lists up to 25 working days for standard paper legalisation, up to 2 working days for an e-Apostille, next-day service for eligible registered businesses and a restricted urgent same-day service with pre-approval.

Do non-Hague countries need more than an Apostille?

Often yes, because further embassy or consular legalisation may be required before the document can be used in the destination country.
