Who can certify documents in the UK?
The UK governments website states that ‘Your document must be certified by a professional person or someone well-respected in your community (‘of good standing’). This could be a solicitor, doctor or minister of religion. They must not be related to you, live at your address or be in relationship with you. You can find a list of individuals here.
How to certify a document in the UK?
Take both the original document and a clear photocopy to an appropriate professional and ask them to certify the copy. The certifier should write on the document: “Certified to be a true copy of the original seen by me”, then sign and date it. They should also print their name clearly and include their occupation, business address, and contact telephone number.
A solicitor will be able to carry out this certification for you, and this is often the most widely accepted option.
Why do you need a solicitor to witness your signature?
Certain documents such as passports, mortgages and wills for example do require an independent, qualified person to confirm that the signature is genuine. This will be stated on the document you have. A qualified solicitor simply acts as an impartial witness, confirming that you signed the document voluntarily and understood what you are signing. This helps prevent fraud and ensures your document will be accepted by banks, lenders, and government authorities.
Do I need a notary to sign my passport?
Did you know, many clients are told they need a notary for a wide range of documents, including Irish and South African passports. In most UK cases, this is unnecessary. It is only needed for overseas. However, if you’re using our services we will always confirm the correct level of signing before you book.

What does a solicitor do as a witness?
When a solicitor witnesses your signature, they will first verify your identity by asking you for a form of ID, such as a passport or driving licence. In addition they may also ask for a recently utility bill or council tax bill to cross reference your ID. They will then observe you sign the document and add their own details — including name, firm, address and qualification, this is to confirm the signature was made in their presence. In some cases, such as guarantee or indemnity forms, the solicitor may also need to confirm that you understand the legal implications before signing.
What do you need to bring to the appointment?
To make the process smooth, please bring:
- Valid photo ID (passport or driving licence)
- Proof of address (such as a utility bill or bank statement dated within the last three months)
- The original document you need witnessed or certified. If you need certified copies, please bring both the original and the copies you’d like certified.

Do all documents require a solicitor to act as a witness?
Not always. Some forms can be witnessed by another professional, such as a doctor, teacher, or accountant. However, when the document has legal or financial implications — such as property transactions, affidavits, guarantees or official identity verifications — a solicitor’s certification is usually required. The company requesting the documentation will specify whether you need it to be dealt with it by a solicitor.
If you need a document signing our solicitors can arrange to meet you locally in either Woking or Cambridge. Alternatively, we hold appointments in central London, in the beautiful surrounds of Lincoln’s Inn.
For ease, we offer Saturday appointments if our clients struggle to meet during the week and on special occasions can see clients between 6 pm and 7 pm during week.
