A foreign bank rejects a power of attorney, a property completion abroad is delayed, or an overseas authority asks for an apostille. At that point, the difference between a notary vs solicitor UK appointment is no longer academic. Choosing the wrong professional can mean having to repeat the paperwork, lose valuable time and pay additional fees.

Both notaries and solicitors are regulated legal professionals. However, they serve different purposes. A solicitor is generally the right person for legal advice and transactions governed by the law of England and Wales. A notary public is usually required when a document must be accepted, relied upon or registered outside the UK.

Notary vs Solicitor UK: the key difference

A solicitor advises clients on legal rights, obligations and risks. They may draft contracts, deal with disputes, conduct conveyancing, prepare wills, advise companies and represent clients in many legal matters. A solicitor can also witness signatures and certify certain copies of documents where this is appropriate.

A notary public has a distinct international function. A notary verifies identity, capacity and understanding, witnesses signatures, certifies copies and authenticates documents for use in foreign jurisdictions. The notary applies a formal seal and signature, which allows the document to be recognised internationally, often after an apostille or consular legalisation.

In practical terms, a solicitor helps you understand and protect your legal position. A notary helps ensure a document is formally executed in a way that an overseas recipient can trust.

There can be overlap. Some solicitors are also notaries, but not every solicitor is a notary public. Where a foreign authority has specifically requested notarisation, a solicitor’s certification alone may not be enough.

When a solicitor is the right choice

A solicitor is normally your first point of contact where the main issue is legal advice rather than international document authentication. For example, you may need a solicitor when buying or selling a UK property, resolving a business dispute, preparing a will, handling probate, negotiating a contract or receiving immigration advice.

Solicitors are also well placed to draft documents that will later need notarisation. A company may ask its solicitor to prepare a board resolution, shareholder resolution or power of attorney. Once the wording is agreed, a notary may then authenticate the final document for use overseas.

For domestic matters, a notary is often unnecessary. If a UK pension provider, employer, university or public body only needs a copy certified, it may accept certification from a solicitor, accountant, doctor or other approved professional. Always check the recipient’s exact requirements before arranging an appointment.

When you need a notary public

You are likely to need a notary where the document is going abroad or where an overseas organisation expressly asks for a notarised, notarised and apostilled, or legalised document. This is common for individuals, directors and professionals dealing with another country’s authorities.

Typical examples include powers of attorney for overseas property transactions, affidavits and statutory declarations, passport and degree copies, documents for marriage abroad, and consent forms for children travelling or relocating internationally. Businesses frequently require notarisation for certificates of incorporation, board resolutions, commercial agreements, certificates of good standing and documents appointing overseas representatives.

A notary does more than witness a signature. They must be satisfied as to the signer’s identity, legal capacity and willingness to sign. Depending on the document, the notary may need to check company records, constitutional documents, board authority, supporting evidence and the requirements of the destination country.

That level of due diligence is one reason overseas authorities place weight on a notarial seal. It is also why clients should not sign documents in advance unless the notary has specifically confirmed that this is acceptable.

Certification is not always notarisation

This distinction causes many avoidable problems. A certified copy is usually a copy marked as a true copy of an original document. A solicitor may be able to provide this service for many UK purposes.

Notarisation is more formal. The notary may certify the copy, but they also add their official seal, signature and notarial wording. They keep a detailed record of the act in their register. Foreign courts, government departments, banks and registries often require this formal process because they need assurance that the person or document has been independently verified.

If an overseas recipient asks for a “notarised copy”, do not assume a standard solicitor-certified copy will be accepted. Ask whether it also requires an apostille from the Foreign, Commonwealth & Development Office or legalisation by the relevant embassy or consulate.

Apostille and legalisation: the step after notarisation

Notarisation and apostille are separate stages. The notary confirms the document and applies their seal. An apostille then verifies the notary’s signature and status for use in countries that are party to the Hague Apostille Convention.

For some countries, an apostille is the final step. For others, including jurisdictions that require consular legalisation, the document may need further authentication by an embassy or consulate after the apostille has been issued.

The correct route depends on the destination country and the type of document. The UAE, Qatar, Saudi Arabia, China, India, Spain and the USA all have different practical requirements, and these can change depending on the receiving authority. A document accepted by one overseas bank may not meet the requirements of a land registry, court, university or government ministry in the same country.

This is where specialist notarial guidance can save time. Before notarisation, the notary can identify whether the document needs an apostille, consular legalisation, a certified translation, specific wording or particular evidence of corporate authority.

Can a solicitor notarise a document?

Only if that solicitor is also appointed as a notary public. The title “notary public” is separate from the title “solicitor”, and notarial work involves its own professional duties and international standards.

It is sensible to ask directly whether the professional can provide a full notarial act and arrange any required apostille or legalisation. A solicitor who cannot notarise may still be able to advise on the document’s legal content, but you will need a notary for the international authentication stage.

For clients with a complex matter, a dual-qualified solicitor and notary can be particularly useful. The same professional can consider both the legal wording and the formalities required for overseas use, although the scope of advice should always be agreed at the outset.

What to bring to a notary appointment

Preparation matters, especially where there is a deadline. A notary will usually need to see the original document to be signed or copied, valid photographic identification and proof of your current residential address. For corporate work, they may also require company incorporation details, constitutional documents, a recent Companies House record and evidence that the person signing has authority to do so.

Bring the instructions from the overseas recipient if you have them. An email from the foreign lawyer, bank, authority or agent can be extremely helpful because it may specify whether the document must be notarised, apostilled, legalised or translated.

Do not alter the document or add dates after notarisation without checking first. A later change can invalidate the notarial act and require the document to be completed again.

Choosing the right professional without delay

If the matter is UK-based and you need advice, drafting or representation, start with a solicitor. If the document is intended for use abroad, has been requested by a foreign authority, or needs an apostille or embassy legalisation, contact a notary public first.

Where timing is tight, explain the destination country, document type and deadline at the beginning. A specialist service such as White Horse Notary Public can assess the likely formalities, confirm the identification needed and arrange an appointment suited to urgent personal or corporate requirements.

The safest approach is simple: follow the requirements of the organisation receiving the document, not assumptions based on what was accepted previously. A few checks before signing can prevent a costly rejection after the document has already travelled halfway around the world.
