Commissioner for oaths, solicitor and Notary Public compared

Commissioner for oaths, solicitor, Notary Public: what the difference means for you

In the UK, a commissioner for oaths administers oaths and takes declarations, and a solicitor can witness a signature or certify a copy. Both are recognized for documents used within the UK. A Notary Public does all of that too, and adds the piece that matters when the document is going abroad: a notarial seal, signature and certificate that foreign courts, authorities, banks and employers recognize across borders.

If your document is staying in the UK, any of the three may serve. If it is going to another country, or the receiving party used the word “notarized”, the notarial version is the one to get, and it is what NotaryPublic24 provides.

Get your affidavit, declaration or signature certified from home

You upload the affidavit, declaration or letter as a clear scan or photo. After checkout you complete a guided identity verification with a biometric and ID check, which usually takes a few minutes. A qualified Notary Public is appointed to your case, reviews the document, and certifies it with seal, signature and a notarial certificate stating what was verified and when.

There is no appointment to book and no office to visit. If the document needs anything before it can be certified, such as a missing date or a signature in the wrong place, you are told before work starts, so nothing is charged for a document that cannot be completed.

This is what you get back

Your affidavit, declaration or signed document as a PDF, with the seal and signature of your appointed Notary Public and a notarial certificate. A foreign court, embassy, bank or employer can check the certificate, and you can forward or print the file as many times as you need. If the receiving party insists on a paper original, a hard copy is posted on request.

Delivery is within 24 hours of identity verification. If the receiving authority also requires an Apostille, which is common for court and government use abroad, International Apostille includes the notarization in one order.

Frequently asked questions

Can a Notary Public do what a commissioner for oaths does?

For a document going abroad, yes, and more. A Notary Public certifies your affidavit or declaration with a notarial seal and certificate that is recognized internationally. For a document used only within the UK, a commissioner for oaths or a solicitor may be what the receiving party expects; check their instructions.

Do I have to swear the oath in front of someone?

With International Notarization the identity verification is a guided biometric and ID check that you complete online. Your appointed Notary Public then certifies the document. If your receiving party specifically requires an oath administered in person, contact support before ordering.

Can you witness my signature?

Yes. Signed letters, authorizations, powers of attorney and declarations are certified with the notarial seal and certificate after your identity has been verified.

Which documents cannot be handled online?

Wills and codicils, which require in-person witnessing, and documents where the receiving authority explicitly demands an in-person act. If you are not sure, contact support before ordering and you will have an answer within minutes.

How fast is it?

Within 24 hours of identity verification.

Will a foreign court or embassy accept it?

A notarial act by a qualified Notary Public is what courts, embassies and authorities abroad recognize. Many of them also require an Apostille on top. International Apostille includes the notarization if you need both.

What do I need to have ready?

The affidavit, declaration or letter as a clear scan or photo, and a valid passport or national ID for the identity check.

Can you help with the wording of my affidavit or declaration?

The platform offers ready-made affidavit and statutory declaration forms under Services. If you already have a document from a lawyer or the receiving party, upload that.

How much does it cost?

One fixed price per document, shown on the product page before you order. No appointment fee and no travel.
