A foreign bank, registry, buyer or overseas lawyer may ask for a company document to be notarised with very little warning. The document itself may look straightforward, but knowing how to notarise corporate documents correctly often depends on far more than arranging a signature. The notary must be satisfied about the company’s existence, the signatory’s identity and authority, and the form of execution required by the receiving country.

For international use, a document that is signed correctly under English law can still be rejected abroad if it has not been notarised, apostilled or legalised in the expected format. Preparing the right evidence before the appointment is usually the quickest way to avoid delay.

When does a company document need notarisation?

Corporate notarisation is commonly required where a UK company is dealing with an overseas authority or transaction. Typical examples include a power of attorney for a foreign property purchase or sale, board resolutions approving an international transaction, certificates of incorporation, memoranda and articles of association, shareholder resolutions, and documents opening or operating an overseas bank account.

A foreign branch office registration, tender submission, distribution agreement or court filing may also require notarised company papers. The exact requirement comes from the recipient, not from a general UK rule. Some organisations want the notary to witness the director’s signature. Others require a notarial copy of an existing Companies House record, or a notarial certificate confirming that a named individual has authority to bind the company.

It is sensible to obtain the recipient’s written instructions, where possible. Ask whether they require an original, a certified copy, an apostille, embassy or consular legalisation, a translation, and whether there is prescribed wording. A small difference in wording can matter, particularly for documents intended for the UAE, Qatar, Saudi Arabia, China or India.

How to notarise corporate documents: the practical process

The process begins before anyone signs. Sending clear scans of the document and the overseas requirements to the notary allows the necessary checks and certificate wording to be considered in advance. It also helps identify whether the document needs to be executed in a particular way.

Confirm the company’s status and structure

A notary will usually need current evidence that the company exists and is in good standing. For a company incorporated in England and Wales, this may include a recent Companies House extract, certificate of incorporation, and the company number. Where relevant, the notary may also need the memorandum and articles of association.

The level of evidence depends on the matter. A simple authority letter may require less supporting material than a high-value overseas property transaction or a power of attorney granting substantial powers. If the company is part of a group, owned by an overseas parent or has an unusual shareholding structure, additional documents may be needed to establish the chain of authority.

Companies House information is useful, but it is not always enough on its own. It may show who is recorded as a director, yet the notary still needs to understand whether that director can sign this particular document and whether any internal approvals are required.

Prove the signatory’s identity and authority

Each person signing before the notary must provide suitable original identification, normally a valid passport or UK photocard driving licence, together with proof of their residential address. The notary may conduct further verification where appropriate.

Authority is equally important. A director may have authority under the articles, a board resolution, a shareholder resolution or a specific power of attorney. The evidence should match the document. For example, if a board resolution authorises two directors to execute a power of attorney jointly, one director should not attend alone and sign without further authority.

Under section 44 of the Companies Act 2006, a company may generally execute a document through two authorised signatories, or by one director in the presence of a witness who attests the signature. However, the receiving jurisdiction may impose a different practical expectation. Some overseas recipients insist on a particular number of directors, a company secretary, a corporate seal, or a notarial form that does not mirror standard UK practice. The document should therefore be reviewed before signing, rather than corrected afterwards.

Sign in the notary’s presence where required

Do not sign or date the document prematurely unless you have been told this is acceptable. Where the notary is witnessing execution, the signatory must usually sign in the notary’s presence. The notary will check that the person understands the document and is signing willingly, then complete the notarial certificate, signature and official seal.

For a certified copy, the process is different. The notary compares the copy against the original and certifies what has been seen. This does not necessarily confirm the truth of the document’s contents, nor does it automatically confirm that a signatory had authority at the time it was originally signed. These distinctions matter when a foreign authority has asked for a specific type of certification.

Arrange an apostille or further legalisation

Notarisation is often only the first stage. If the destination country is party to the Hague Apostille Convention, the notary’s signature and seal may need an apostille from the UK Foreign, Commonwealth and Development Office. The apostille verifies the notary’s official capacity for use in another convention country.

Where the destination is not covered by the Convention, further legalisation through the relevant embassy or consulate may be required after the apostille. Requirements can change, and some embassies have their own rules on document format, translations, company stamps and processing times.

This is why the destination country should be confirmed at the outset. A document prepared for use in Spain or the United States may follow a different route from one intended for the UAE or China. There is no advantage in arranging an apostille if the recipient actually requires consular legalisation as well.

Documents to bring to a corporate notary appointment

Bringing complete information allows the notary to deal with the matter efficiently. In most cases, the signatory should be ready to provide the original corporate document or clear final version, current photographic identification and recent proof of address. The notary will also need company details and supporting evidence of authority, such as a board resolution, the articles of association or a power of attorney.

For more complex matters, it is helpful to provide the foreign recipient’s instructions, any template certificate supplied by an overseas lawyer, and details of the intended legalisation route. If documents are in another language, a translation may be required. The notary can advise whether the translation itself needs certification or notarisation.

Avoid relying on an unsigned draft resolution as proof of authority. Equally, do not assume that a director’s job title is enough. The notary’s role is to make an independent assessment based on suitable evidence, and that assessment protects both the company and the recipient abroad.

Common reasons corporate documents are rejected abroad

The most frequent problems are preventable. A document may be rejected because it was signed before the notarial appointment, the names do not match the company register, the board resolution does not authorise the transaction clearly, or the wrong legalisation route was used.

Another common issue is using an outdated company extract or failing to account for a recent change of director, registered office or company name. Overseas institutions may also refuse documents that are older than three or six months, even where the document remains legally valid in the UK.

There can also be a mismatch between the document and the notarial certificate. If the recipient needs confirmation of a director’s authority, a simple witnessed signature may not be sufficient. If it needs a certified copy of a certificate of incorporation, asking the notary to witness a director signing a copy will not achieve the intended result.

Timing, remote appointments and urgent matters

Timescales depend on the number of signatories, the quality of the supporting documents and the legalisation required. A straightforward signing can often be handled promptly once the paperwork has been reviewed. Apostille and consular stages take additional time, particularly where an embassy has appointment or submission requirements.

Remote electronic notarisation may be suitable for certain corporate documents and jurisdictions, but not every recipient will accept it. The governing law of the document, the destination country’s rules and the recipient’s own policy must all be checked. For documents requiring wet-ink signatures, a physical appointment remains the safer route.

White Horse Notary Public can review corporate documentation in advance, verify the appropriate execution process and coordinate apostille or legalisation support where required. Early review is particularly valuable when a transaction involves multiple directors, overseas advisers or a fixed completion date.

A well-prepared notarial appointment is not simply an administrative step. It is the point at which your company’s authority and documents are put into a form an overseas recipient can trust, allowing the transaction to proceed with fewer questions and less risk of last-minute rejection.
