About the Affidavit For Change Of Signature

An Affidavit For Change Of Signature is a sworn legal document that allows you to formally register a signature change with institutions and organizations across Canada. This document provides legal verification under the Canada Evidence Act when you need to update your signature for any reason, creating an official record that prevents future authentication problems.

When do you need this document?

You'll need this affidavit when changing your signature due to medical conditions affecting handwriting, physical injuries to your dominant hand, arthritis or other age-related changes, or simply personal preference for a different signature style. It's also commonly required after marriage when adopting a spouse's surname, following legal name changes, or when your signature has naturally evolved over time and no longer matches official records. Banks, government agencies, insurance companies, and legal institutions often require this affidavit before accepting your new signature on important documents.

Key legal considerations

Your affidavit must include both specimen signatures clearly displayed, with your previous signature shown alongside your new one for comparison purposes. The document must contain a detailed explanation of why you're changing your signature, your complete legal identification including full name and address, and the specific date you're implementing the change. You must swear the affidavit before a commissioner of oaths or notary public, who will verify your identity and witness your signatures. The affidavit becomes a permanent legal record, so ensure all information is accurate and complete before signing. Consider informing all relevant institutions simultaneously to avoid confusion during the transition period.

Legal requirements in Canada

Under the Canada Evidence Act and provincial notary legislation, your Affidavit For Change Of Signature must be properly sworn and witnessed by an authorized official. Commissioners for taking affidavits, notaries public, and lawyers are typically qualified to administer the oath and authenticate your document. Provincial requirements may vary slightly, but all jurisdictions require proper identification verification and witnessed signature samples. The Bank Act mandates that financial institutions maintain updated signature records, making this affidavit essential for banking relationships. Some provinces require additional witness signatures or specific formatting requirements, so verify local regulations before completing your affidavit. Keep multiple certified copies for distribution to various institutions, as many organizations require original or certified copies rather than photocopies.
