A bank in Dubai, a registry in Spain or a supplier in China will often ask for company papers to be notarised before they will accept them. That is usually the point when directors, company secretaries and in-house teams start asking how to notarise company documents properly – and how to do it without delays, rejected paperwork or unnecessary cost.
The short answer is that a notary public must verify the document, the identity of the signatory and, where relevant, the authority under which that person is signing for the company. The detail matters, though, because corporate documents are rarely treated as simple paperwork. If a foreign authority is relying on a resolution, certificate or power of attorney, it wants confidence that the company exists, the right person signed, and the document can be trusted overseas.
How to notarise company documents correctly
The first step is to identify exactly what the receiving authority wants. In some cases, a simple certified copy by a notary is enough. In others, the notary must witness a signature, prepare a notarial certificate, or notarise a board resolution or power of attorney. If the document is going abroad, it may also need an apostille or embassy legalisation after notarisation.
This is where many delays begin. Businesses are sometimes told only that a document must be “notarised”, without any explanation of format. A foreign bank may require a notarised certificate of incorporation and a notarised incumbency statement. A port agent may need notarised shipping documents. An overseas lawyer may insist on a corporate power of attorney signed in front of a notary. These are not interchangeable. Getting clarity at the start saves time and avoids repeat appointments.
Once the document requirement is clear, the notary will usually need to review both the document itself and the company background. That often includes Companies House records, constitutional documents, and proof that the signatory is authorised to act. For some matters, a board minute or board resolution is needed. For others, the notary may accept authority that is already apparent from the company’s filings or internal documents. It depends on the document and the country where it will be used.
What a notary checks for company documents
A notary is not there simply to stamp paper. The role is to verify facts that the overseas authority will rely on. For company documents, that commonly means checking identity, capacity and authenticity.
Identity checks are straightforward in principle. The signatory will usually need a valid passport and proof of address. If the notarisation is carried out remotely, the process may involve electronic ID verification and a video appointment, depending on the type of document and whether remote notarisation is suitable.
Authority is often the more important issue. If a director signs on behalf of the company, the notary may ask for evidence that the director is in office and entitled to sign. If someone other than a director is signing, the notary will want to see the chain of authority. This might be a board resolution, a power of attorney or a written delegation. If the authority is unclear, the document can still sometimes be notarised, but only once the position is properly evidenced.
Authenticity matters as well. Some company documents are originals, such as signed resolutions or powers of attorney. Others are copies of records, such as the certificate of incorporation, memorandum and articles, or Companies House filings. A notary may certify copies, but only after checking the original or a reliable official source. If the receiving authority requires a notarial certificate in a specific form, that wording should be checked in advance.
Which company documents are commonly notarised
Corporate notarisation covers a wide range of documents. The most common include powers of attorney, board resolutions, certificates of incorporation, memorandum and articles of association, shareholder resolutions, director certificates, bank documents, compliance papers and cross-border transaction documents. For trading businesses, it can also extend to shipping documents, invoices, agency agreements and certificates needed for customs or overseas tenders.
The right approach depends on the document. A notarised power of attorney usually requires execution before the notary. A certified copy of incorporation records is different – the notary is confirming that the copy matches the original or an official record. A board resolution may need to be signed in a particular way under the company’s articles. There is no single process for every document, which is why advance review is useful.
If documents are destined for more than one country, requirements can become more complicated. One jurisdiction may accept a notarised copy. Another may insist on apostille. A third may require embassy legalisation and a sworn translation. Coordinating those steps early is often the difference between a smooth filing and a missed deadline.
The practical process from start to finish
If you need to know how to notarise company documents efficiently, think of it as a staged legal check rather than a quick administrative task. The process normally starts with sending the document and any instructions from the overseas authority to the notary for review. That review helps confirm what type of notarisation is required and what supporting papers are needed.
You will then be asked for company evidence and personal ID from the signatory. Depending on the matter, this may include Companies House details, the certificate of incorporation, articles of association, proof of directorship, and any board resolution authorising the signing. If the document is urgent, preparing these in advance can save a great deal of time.
The signing stage depends on the document. Some papers must be signed in the presence of the notary. Others may already be signed, provided the notary is able to verify the signature or certify the document in another appropriate way. This is not an area for guesswork. If a document is signed too early, the notary may require it to be signed again.
After the notarisation itself, the document may need an apostille from the Foreign, Commonwealth and Development Office. If the destination country is not covered by the apostille system, consular legalisation may also be required. Many business clients underestimate this stage. The notarisation appointment may be arranged quickly, but embassy legalisation can add time depending on the country and the paperwork involved.
Common problems that slow corporate notarisation
The most frequent issue is missing authority. A company may assume that any senior employee can sign, but the notary has to be satisfied that the signatory is properly authorised. If the transaction is high value or the receiving authority is strict, informal internal approval will not usually be enough.
Another common problem is poor document preparation. Drafts arrive with blank fields, inconsistent company names, unsigned attachments or foreign language wording that has not been checked. Notaries can help identify issues, but they cannot safely notarise unclear or incomplete paperwork. A small drafting error can create a large delay once the document reaches the overseas authority.
Timing is also a practical issue. If documents need apostille or embassy legalisation, leaving the matter to the last minute creates avoidable pressure. Urgent appointments are often available, and firms such as M M Karim Notary Public London are set up to assist with time-sensitive international documentation, but speed works best when the paperwork is complete from the outset.
In-person, mobile and remote options
Many company clients still prefer a traditional in-person appointment, especially where original corporate documents or wet-ink signatures are required. That remains the safest route for many powers of attorney, transactional papers and high-value matters.
Mobile appointments can help when several directors need to sign, or when the signatory cannot easily attend an office. This can be especially useful for businesses working to shipping, banking or completion deadlines.
Remote notarisation can also be appropriate in some cases. It is particularly useful for clients outside London or outside the UK, but it is not suitable for every document or every jurisdiction. Some overseas authorities still insist on paper originals or specific execution formalities. The sensible approach is to check first, rather than assuming that an online notarisation will always be accepted.
Fees vary according to the type of document, the number of documents, the complexity of the corporate checks and whether apostille or legalisation is needed. The cheapest route is not always the fastest if documents have to be redone. Equally, not every company matter is complex. A straightforward certified copy of incorporation records is very different from a multi-document overseas banking pack. Clear pricing and early review help avoid surprises.
If you are preparing documents for use abroad, treat notarisation as part of the transaction, not as an afterthought. The more clearly you can show what the document is, who is signing it and where it is going, the easier it is to get the job done quickly and correctly.
