If you have recently signed a Will or a Power of Attorney, you’ve likely heard the term Affidavit of Execution. While it sounds like a mouthful of legal jargon, it is actually one of the most critical documents in your estate planning toolkit.
At Snap Notary, we help Ontarians ensure their legal documents are bulletproof. Here is a clear breakdown of what this document is and why it cannot be overlooked.
What is an Affidavit of Execution?
In Ontario, an Affidavit of Execution is a sworn statement made by one of the people who witnessed you signing your Will or Power of Attorney.
In this document, the witness confirms under oath that:
Why is it so important for Probate?
Think of the Affidavit of Execution as the "verification key" for your Will. When a person passes away, the Ontario Court usually requires this affidavit to grant Probate (a Certificate of Appointment of Estate Trustee).
Without this affidavit, the court has no immediate proof that the Will was signed according to the strict requirements of the Succession Law Reform Act. If your witnesses cannot be found years later, your family could face significant delays and expensive legal hurdles to prove the Will is valid.

Tips for a Smooth Notarization
Complete it early: It is much easier to complete the Affidavit of Execution right after the Will is signed, while the witnesses are still available and their memories are fresh.
Bring the Original Document: The Notary must see the original Will or Power of Attorney to properly "mark" it as an exhibit.
Valid ID: The witness must bring a valid piece of government-issued photo identification.
