Self-Proving Affidavits
Learn what a self-proving affidavit is, how it strengthens the legal standing of a Will or Power of Attorney, and why it helps simplify probate or care decisions
A self-proving affidavit is a legal document that affirms a Will or Power of Attorney was signed properly, with witnesses who observed the signing and can verify the signer’s identity and capacity. It acts as a sworn statement, usually signed by one or both witnesses at the time the Will or POA is executed.
This simple step can prevent delays, reduce court questions, and ease the administrative burden on your executor or attorney.
How a Self-Proving Affidavit Strengthens Your Legal Documents
Self-proving affidavits are most commonly used with Wills but can also accompany Powers of Attorney. They give the court assurance that your documents were signed under the correct conditions and do not require your witnesses to appear in person.
| Function | How It Helps |
|---|---|
| Confirms proper execution | Shows the document was signed voluntarily and with proper witnesses |
| Reduces need for witness testimony | Courts can accept the affidavit instead of calling witnesses later |
| Speeds up probate | Eliminates delays caused by locating witnesses or validating signatures |
| Adds legal weight to your documents | Helps prove the Will or POA is genuine if challenged |
Tip: Ask your lawyer or notary to include a self-proving affidavit when you sign your Will. It adds little cost but can save time and stress later.
What a Self-Proving Affidavit Contains
A standard self-proving affidavit typically states that:
-
The person signed the Will or POA in the presence of the witnesses
-
The person appeared to be of sound mind and acted voluntarily
-
The witnesses signed in the presence of the person and each other
The affidavit is signed under oath, often in front of a commissioner for oaths, notary public, or lawyer.
Important: While self-proving affidavits are not required in all provinces, they are widely accepted and recommended for smoother probate and healthcare decision-making.
Using Affidavits with Powers of Attorney and Living Wills
Although more commonly associated with Wills, a self-proving affidavit can also support your Power of Attorney or advance directive. It reinforces that:
-
You were capable when signing
-
Your witnesses were eligible and present
-
The document meets legal standards of execution
This is especially helpful if your POA or living will is ever questioned by healthcare providers or family members.
