Signing and Witnessing a Will in Canada: Legal Rules Explained

A Will isn’t legally valid until it’s signed and properly witnessed. This final step turns your document into a binding legal record of your wishes. Improper witnessing is one of the most common—and costly—mistakes Canadians make.

For drafting steps and context, see our Complete Canadian Will Guide.

Core Requirements

• The Will must be in writing.
• You sign at the end of the document.
• Two adult witnesses sign in your presence and in each other’s presence.
• Witnesses must not be beneficiaries or spouses of beneficiaries.

Who Can—and Cannot—Witness

• Can: Independent adults (18+ or 19+ depending on province) of sound mind.
• Cannot: Beneficiaries, their spouses, or anyone not present at the signing.

Witnesses do not need to read your Will; they simply verify your signing.

Tips to Avoid Challenges

• Use blue ink so originals are distinguishable.
• Initial each page.
• Sign together in one sitting on a flat surface.
• Store the original securely and inform your executor.
