Affidavit For Change Of Signature Template for England and Wales

An Affidavit For Change Of Signature is a sworn legal document that formally notifies institutions of your decision to change your official signature. When you need to update your signature across banks, government agencies, or legal documents, this affidavit provides the legal framework to make the transition official and reduce the risk of a signature mismatch being treated as fraud under the law of England and Wales.

What is a change in signature affidavit?

It is a written statement, sworn as true before a solicitor or Commissioner for Oaths, in which you confirm that you are moving from one signature to a different one. The document sets out your identity, records your full name as it appears on official records, captures specimens of both the old and new signatures side by side, and states that the change is voluntary. Because it carries the weight of a sworn oath, institutions treat it as reliable proof and update their records accordingly. The same affidavit can cover a wet-ink signature on paper and an electronic signature used on digital documents.

When do you need this document?

You need this affidavit when your signature has changed significantly, for example because of a medical condition affecting your handwriting, a marriage or divorce requiring a name change, or a deliberate change made for professional consistency. Banks and financial institutions often ask for it when they notice discrepancies between your current signature and the one on file. It is also useful when updating estate planning documents, contracts, or business agreements where signature consistency matters, and when a finance or operations team needs to keep customer and supplier records accurate. Government agencies may request the document when processing applications or renewals that require signature verification, and your passport, driving licence, and other identity records may need to align with the new signature too.

What should the affidavit contain?

A complete affidavit for a change in signature usually includes:

• Your full legal name, including first name and surname, and identifying details verified against government-issued identification such as a passport or driving licence.
• A clear statement of your intention to change your signature, made voluntarily and without coercion.
• Specimens of both the old and new signatures so the difference is on record, including any change to how you render your initials.
• The reason for the change, if relevant, such as a medical condition, with supporting documentation where it helps.
• The jurat, the section confirming when and before whom the affidavit was sworn.

Setting out this content clearly helps the institution act quickly and gives them a single reference for future verification.

What does a change in signature affidavit look like?

A typical opening reads along these lines: "I, [full name], of [address], do solemnly and sincerely swear that I have changed my signature from the specimen marked 'old signature' to the specimen marked 'new signature' shown below, and that this change is made voluntarily." Below that sit two boxes, one holding the old signature and one holding the new, followed by the date and the jurat completed by the solicitor or Commissioner for Oaths. Recording the full name first and the two specimens together is what lets a bank or registry match the person to both signatures without ambiguity.

How is the affidavit made valid?

In England and Wales the affidavit must be sworn before a solicitor, a Commissioner for Oaths, or a court officer, who then completes the jurat. Making a false statement in a sworn affidavit is a criminal offence, so the content must be accurate and honest. Keep a signed copy for your own records and provide certified copies to each institution that needs one, so the same evidence supports every account, contract, or registration affected by the change.

Digital and electronic signatures

A change of signature is no longer just a matter of ink on paper. Many agreements are now signed online with a digital signature on a platform such as DocuSign, so your affidavit should make clear that the new signature applies to both wet-ink and electronic use. The legal position is simple: an electronic signature is admissible evidence in England and Wales, provided it reliably identifies the person signing and shows their intent to be bound. When you sign contracts electronically, keeping the affidavit alongside your records helps operations and finance teams reconcile identity across every system, from banking KYC files to an electronic signature workflow. Storing these records securely, with limited access, keeps personal data protected while every recipient still has the proof it needs.

How does a signature change affect existing agreements?

A new signature does not invalidate documents you signed before, but it does matter for anything still in force. Across the contract lifecycle, from a signed service agreement through to a non-disclosure agreement, institutions and counterparties rely on signature consistency to verify that it is genuinely you. Attaching the affidavit to your record management keeps every agreement traceable to one verified identity, so a later amendment, renewal, or audit confirms the full name and the specimen on file still match the person signing today. If you want to understand the mechanics in more detail, our guide to the electronic signature explains how digital signing stays legally valid.

How does this affidavit protect your privacy?

The document contains personal data, including signature specimens, so the institutions that receive it must process and store it lawfully and securely. Provide the affidavit only to organisations that genuinely need it, and ask how they will retain the specimens. Keeping distribution limited protects your privacy while still giving each recipient the proof they require.
