A bank in Dubai asks for an apostilled board resolution. A buyer overseas needs proof that your UK company exists. A new distributor will not sign until it receives a legalised power of attorney. In each case, the document may be perfectly valid in the UK but still unusable abroad. This guide to company document legalisation explains how to prepare corporate paperwork so that a foreign authority can accept it without avoidable delay.
What company document legalisation means
Company document legalisation is the process of confirming the authenticity of a UK corporate document for use in another country. It does not approve the commercial deal, verify every statement in the document, or replace legal advice on the underlying transaction. It confirms that the signature, seal or official capacity on the document can be relied on by the receiving country.
The route depends principally on where the document will be used. For countries party to the Hague Apostille Convention, the usual final step is an apostille issued by the UK Foreign, Commonwealth and Development Office. An apostille is a certificate attached to the document or its notarial certificate. It allows the document to be recognised in another convention country without further embassy legalisation.
Where the destination country is not part of the Convention, the document commonly needs an apostille followed by consular legalisation at that country’s embassy or consulate. Some jurisdictions have their own prescribed forms, translation rules, or requirements about how recently the document was signed. The requesting bank, authority, counterparty or overseas lawyer should confirm the required route before the document is executed.
When a company needs legalised documents
The request usually arises when a business is proving its authority or identity beyond the UK. Common examples include a corporate power of attorney for an overseas property purchase, board resolutions approving a foreign transaction, certificates of incorporation, constitutional documents, bank mandates, share certificates, commercial agreements and shipping paperwork.
Businesses also encounter legalisation when opening an overseas bank account, establishing a branch or subsidiary, appointing an agent, registering for a tender, dealing with customs, or making a claim through an overseas insurer. A foreign recipient may ask for documents that establish who the directors are, who owns the business, and who has authority to sign.
The exact package varies. A bank may require a power of attorney, a board resolution and certified incorporation documents. A foreign registry may require an application form signed before a notary, together with an apostilled certificate of good standing. Treat each request as a document-specific instruction rather than assuming that one apostille covers the whole transaction.
The usual route for company document legalisation
1. Confirm the receiving country and its requirements
Start with the destination country, the organisation receiving the papers and the intended purpose. Ask whether it requires an apostille only, full embassy legalisation, notarisation, certified copies, a translation, or a particular form of wording. It is also sensible to ask whether original documents are needed and whether the authority accepts electronically signed documents.
This is the point at which many delays can be avoided. “Legalised” is sometimes used loosely by overseas organisations to mean notarised, apostilled or both. A clear written instruction from the recipient is far more useful than relying on the label alone.
2. Prepare the correct corporate evidence
A notary must be satisfied that the company exists and that the person signing has the authority to do so. Depending on the document and company structure, this may involve reviewing the certificate of incorporation, current Companies House information, articles of association, registers, board minutes or resolutions, and identification for directors or authorised signatories.
The evidence should match the transaction. If a director signs a contract under a board authority, the resolution should identify the transaction and provide the necessary authority. If an attorney is appointed, the power of attorney should be properly drafted and the scope of authority should be clear. A vague resolution may be accepted by neither the notary nor the overseas recipient.
3. Arrange notarisation where required
Notarisation is often the key step before legalisation. The notary verifies the signatory’s identity, capacity and authority, witnesses the signature where appropriate, and attaches a notarial certificate or notarial seal. For certified copies, the notary compares the copy with the original document and certifies it according to the requirement.
Not every document needs notarisation before an apostille. For example, certain public documents may follow a different route. However, corporate documents created or signed privately commonly need a notarial act so that the apostille can authenticate the notary’s signature and seal. The correct approach depends on the document, its origin and the destination country’s rules.
4. Obtain an apostille or consular legalisation
After notarisation, an apostille can be obtained for use in a Hague Convention country. If the country requires consular legalisation, the apostilled document is then submitted to the relevant embassy or consulate. That additional stage can add time, particularly where an embassy operates appointments, requires a translation, or accepts submissions only on certain days.
Do not separate documents that have been bound together by the notary. Removing, replacing or adding pages can invalidate the notarial certificate or create questions over the integrity of the document. Keep the completed set intact until it reaches the recipient.
Documents that need particular care
Corporate powers of attorney deserve close attention because they allow one person to act for the company abroad. The document should state the company’s correct name and registration details, identify the attorney accurately, and set out powers that are broad enough for the overseas purpose but not wider than intended. The receiving jurisdiction may insist on specific wording, a witness, a seal, or a defined validity period.
Board resolutions need the same discipline. They should record the right decision-maker, meeting or written procedure, quorum where relevant, and authority for the named signatory. A resolution that simply says a director may “deal with overseas matters” can be too imprecise for a foreign bank or registry.
Certificates and company records can also cause difficulty. A document downloaded from Companies House may be useful evidence, but an overseas recipient might require an official certified copy, a notarially certified copy, or a fresh certificate obtained within a stated period. Always check what form of evidence it will accept.
Electronic signatures, remote appointments and originals
Electronic signatures are increasingly used in commercial transactions, but acceptance abroad is not universal. A foreign authority may accept an electronic signature on the contract itself while refusing to legalise it, or may require a wet-ink signature for a power of attorney. The issue is not whether electronic signing is convenient but whether the final recipient will accept the legalised result.
Remote electronic notarisation can be helpful where signatories are outside London or abroad, subject to the document type, identity checks and destination requirements. In other cases, an in-person appointment or mobile notary visit is the safer route, particularly where originals or wet-ink signatures must be handled. The right method should be chosen before anyone signs, not after a document has been circulated.
Avoiding the most common causes of delay
The main problems are usually practical rather than complex. Names differ between the document and company records. A director has signed without a supporting resolution. The recipient has asked for a translation only after apostille processing has begun. Or the business has assumed that an apostille is enough when the embassy also requires legalisation.
Before arranging an appointment, have the final draft ready, provide the destination country and recipient’s instructions, and gather the company records that establish signing authority. Tell the notary if there is a deadline, a signing party overseas, or a need for mobile or remote support. Early information allows the appropriate route to be planned and prevents unnecessary repeat appointments.

A practical final check before submission
Before documents are sent abroad, check that the company name, registration number, names of signatories and dates are consistent throughout the pack. Confirm that every page remains attached, that any required translations are complete, and that apostille or consular certificates relate to the correct document. Finally, retain clear copies of the full legalised set and the authority supporting it.
Foreign document requirements can be exacting, but they are manageable when the destination’s instructions are confirmed early and the company’s authority is documented properly. A well-prepared document pack gives your overseas counterparty one less reason to pause the transaction.
