Who Can Be a Witness?

One of the most common and overlooked questions when finalizing a Will is, “Who can be a witness?” The answer matters more than many people realize. The wrong witness can unintentionally invalidate part of your Will or create legal delays during probate.

In Canada, the rules about witnessing a Will are strict, and for good reason. Witnesses are not just bystanders. They are legal participants who confirm that your Will was signed properly, without pressure, and with full understanding.

Legal Requirements for a Will Witness in Canada

Witnesses serve as the official confirmation that your Will was signed voluntarily, with full capacity, and in accordance with the law. They do not need to know the contents of your Will, but they must be physically present when you sign it.

Requirement	What It Means
Must be an adult (age of majority)	Typically 18 or older, depending on the province
Must be of sound mind	Must be capable of understanding the act of witnessing
Must not be a beneficiary	Anyone named in the Will, or their spouse, should not witness your signature
Must be present at the signing	Witnesses must see you sign the Will, and sign in each other’s presence

Tip: Use two neutral witnesses who are not family members and have no stake in your estate. This reduces the risk of your Will being questioned or challenged later.

Who Should Not Act as a Witness

Certain people should never act as witnesses to your Will. If they do, their involvement could cause legal issues, even if your Will is otherwise valid.

Avoid naming as a witness:

Anyone who stands to benefit from your Will
Spouses or partners of beneficiaries
Anyone under legal guardianship or with diminished capacity
People who are not physically present at the time of signing

In most provinces, a gift left to a witness or their spouse will be void, even if the rest of the Will is still valid.

Important: A common mistake is asking a friend or relative to witness your Will without checking their connection to the contents. Always review your Will carefully before finalizing it to make sure your witnesses are truly independent.

What a Will Witness Is Expected to Do

Witnesses are not required to read your Will, give legal advice, or take on any future responsibility. Their role is simple but important.

Witnesses must:

Be physically present when you sign the Will
Sign the document themselves immediately afterward
Provide their full name, address, and contact information

Witnesses do not:

Need to keep a copy of the Will
Become responsible for enforcing the Will
Have access to the contents unless you choose to share them

Some provinces allow for remote witnessing under specific rules. If this applies, additional steps such as video recordings and affidavits may be required.
