A foreign bank asks for proof that your UK company exists, who can sign for it and whether its documents can be relied upon overseas. The request may sound straightforward, but company incorporation documents often need more than an emailed copy from Companies House. Depending on the country and receiving organisation, they may need certified copies, notarisation, an apostille or consular legalisation before they are accepted.

For directors, company secretaries and legal teams, the priority is not simply producing paperwork. It is presenting the right documents in the right form, with a clear evidence trail and no avoidable delay. A document accepted by one overseas bank may be rejected by another, even where the company and transaction are identical.

What are company incorporation documents?

Company incorporation documents are the records that establish a company’s legal existence and set out its basic constitutional and ownership details. In a UK context, the starting point is usually the certificate of incorporation issued when the company was formed. Overseas recipients commonly ask for further material because a certificate alone does not show the company’s current position or prove that a particular individual has authority to act.

The precise package depends on the recipient’s requirements, the destination country and the purpose of the transaction. For example, opening an overseas corporate bank account may require more detailed ownership and signing-authority evidence than entering into a supply agreement. A property purchase, subsidiary registration or cross-border finance transaction can involve a more extensive set of formalities.

Commonly requested documents include:

• the certificate of incorporation;
• the memorandum and articles of association;
• a current company search or extract from the register;
• registers of directors, members or persons with significant control, where applicable;
• board resolutions approving the transaction or appointing an authorised signatory; and
• copies of directors’ passports and proof of address, where due diligence is required.

Some recipients will ask for a certificate of good standing or an equivalent official confirmation. The terminology varies between jurisdictions, so it is sensible to obtain the receiving party’s written requirements before arranging certification or legalisation.

Why overseas recipients ask for notarised documents

A notary does not replace the official register or alter the underlying company records. The role is to verify facts that the receiving authority needs to trust. This can include confirming the identity of a director, reviewing the company’s constitutional documents and official records, and witnessing the execution of a board resolution, power of attorney or other corporate instrument.

For a document signed on behalf of a company, the notary will need to be satisfied that the person signing has the necessary authority. That may involve reviewing a board resolution, the articles of association, Companies House information and relevant identification. If the evidence is incomplete or inconsistent, the document should not be rushed through. Resolving the issue before notarisation is normally far quicker than dealing with an overseas rejection later.

Notarisation is particularly common where a company grants a power of attorney for use abroad, authorises a director or agent to open an account, signs foreign corporate filings, or executes documents for an overseas property transaction. The notarial certificate gives the foreign recipient a formal statement from an independent legal professional as to what was checked and witnessed.

Certification, notarisation and legalisation are different steps

These terms are often used interchangeably, but they serve different purposes. Getting them in the wrong order can lead to duplicated work and missed deadlines.

A certified copy confirms that a copy is a true copy of an original document seen by the certifier. This may be suitable for certain internal, administrative or UK-based requirements. It is not automatically enough for international use.

Notarisation involves a Notary Public applying formal verification and witnessing procedures, then attaching a notarial certificate or seal. The wording and evidence required will depend on the destination and the document. A notary may certify a copy, witness a signature, verify corporate authority, or perform a combination of these functions.

Legalisation is the process that allows a foreign authority to recognise the notary’s signature and seal. For many countries, this takes the form of an apostille issued by the UK Foreign, Commonwealth & Development Office. Countries that are not part of the Apostille Convention may require additional consular legalisation through the relevant embassy or consulate.

The order matters. A corporate document may first need to be properly signed and notarised, then apostilled, and finally presented for consular legalisation. A translation may also be required. The receiving authority should confirm whether it needs the translation notarised, apostilled or completed by a particular type of translator.

A practical way to prepare the documents

The most efficient approach starts with the end user, not the documents you happen to have available. Ask the overseas bank, authority, lawyer or counterparty for its requirements in writing. Request confirmation of the required document list, how recent the documents must be, whether originals are needed, and whether an apostille, consular legalisation or translation is required.

Next, check that the company information is current. Directors, registered office details, shareholdings and persons with significant control should align across the official records, internal registers and proposed resolutions. Differences are not always fatal, but they need an explanation. A bank conducting compliance checks is unlikely to accept an unclear ownership trail simply because the incorporation certificate is genuine.

Then prepare the authority documents carefully. A board resolution should identify the company, the decision being approved, the authorised signatory or attorney, and any limits on their authority. It should be signed in accordance with the company’s articles and applicable law. If the recipient has supplied a form of resolution or power of attorney, have it reviewed before execution rather than assuming a UK-style document will meet foreign requirements.

Finally, allow time for the formalities after notarisation. Apostille and consular processes can be time-sensitive, particularly where documents must be submitted in a fixed order or an embassy has limited appointment availability. Fast service may be available, but speed cannot correct an incomplete document pack.

Original documents versus copies

Whether an original is required depends on the document and the recipient. A certificate of incorporation is often provided as an official document or certified copy, while articles and registers may be copied and certified after the originals have been reviewed. Board resolutions and powers of attorney are commonly signed as originals for notarisation.

Do not assume that a scanned signature or electronic company record will be accepted simply because it is convenient. Remote online notarisation can be appropriate in some circumstances, but acceptance is determined by the law and practice of the destination country and the receiving organisation. Where wet-ink originals are required, this should be identified at the outset.

Common reasons documents are rejected

The most frequent problems are practical rather than complex: documents are out of date, the company name differs slightly across records, the signatory’s authority is not evidenced, or the apostille has been obtained on the wrong document. A further issue is using a generic certificate where the overseas recipient expects a tailored notarial form.

Translation can create another risk. If a receiving authority requires documents in its local language, it may require a certified translation and may specify how names, addresses and company numbers should appear. Translating before the final documents are settled can mean paying twice when a resolution or certificate later changes.

Getting corporate documents ready without delay

For a cross-border transaction, send the document request and deadline to a notary as early as possible, together with the company documents, identification for the proposed signatories and any forms supplied by the recipient. This enables the legalisation route and signing arrangements to be checked before an urgent appointment is booked.

White Horse Notaries can assist businesses with the notarisation, apostille, consular legalisation and translation of corporate documents, while helping to clarify the evidence needed to support a director’s authority. Mobile and remote options may be available where appropriate, although the recipient’s requirements will always determine the correct route.

When company documentation is being relied upon abroad, precision is a practical safeguard. A short review before signing can protect a transaction, a banking application or an overseas filing from weeks of unnecessary delay.
