Key takeaways
  • A probate application normally includes an affidavit of execution (Form 74D), and the original will must be attached to it as an exhibit.
  • Rule 74.04 lists the required forms for each situation, so which forms apply to you depends on the facts of your will.
  • If a judge has to decide an issue, processing takes longer than the usual 15 business days, and a refusal comes with written reasons.
  • What the court will accept in place of a witness's affidavit depends on the facts, so it is worth confirming with a lawyer before you file.

You have found the will and you are named as executor, but the people who watched the deceased sign it have died, moved away or cannot be traced. The usual paperwork assumes one of them can swear an affidavit, so it is natural to worry that the will cannot be proved.

This article explains why the witnesses matter, which parts of a probate application stay the same, how the court handles an application that raises a question, and what you can do to prepare. It is general information about Ontario, not a substitute for advice on your own file.

Why the witnesses matter at probate

A probate application in the Superior Court of Justice includes the deceased's original will and any codicil, proof of death, and a set of completed forms. Among those forms is the affidavit of execution, Form 74D, which is the document that normally speaks to how the will was signed and witnessed.

The original will must be attached as an exhibit to an affidavit of execution, an affidavit of condition or another permitted affidavit. In plain terms, the court wants sworn evidence connected to the actual document, not just a copy and a family member's recollection.

AffidavitWhen it is used
Form 74D, affidavit of executionSpeaks to the signing and witnessing of the will
Form 74E, affidavit of conditionUsed if the will was altered or marked in some way
Form 74F, holograph affidavitAttests to the handwriting and signature of a handwritten will

What changes when a witness is gone

If the witnesses cannot swear the affidavit, the application is no longer routine. Rule 74.04 lists the required forms for each situation, and which of those situations fits your will depends on the facts: who the witnesses were, whether anyone else saw the signing, how the will was prepared and what can be shown about it.

We cannot tell you from general information which substitute evidence a judge will accept in your case. That is a question worth putting to a lawyer early, because the answer shapes what you gather and how the application is prepared.

It helps to understand the cost of uncertainty. Ontario says applications are typically processed within 15 business days, but it can take longer if documents are missing or a judge must decide an issue. How a gap in the witness evidence affects your application depends on the facts, so it is worth confirming with a lawyer.

Parts of the application that stay the same

You still complete Form 74A, signed before a Commissioner for Taking Affidavits, with the value of the real property, personal property and whole estate at the date of death. You also include a draft certificate, Form 74C.

The beneficiary service step matters here. If the witness evidence is thin, someone who was left out of the will, or who expected a bigger share, may take an interest in how the will is proved. Court staff check for other applications, objections and any more recent will.

How the court responds

If the application is refused, the registrar issues Form 74O with reasons. For small estates the equivalent is Form 74.1D, and the notice states the reason, such as a problem in the estate court record search or missing information.

If someone files an objection using Form 75.1, the applicant must serve Form 75.3 on the objector. At that point the matter is moving beyond paperwork and legal advice is strongly worth having.

If the application is granted, the certificate is issued electronically and emailed to the address you provided, unless you asked for a paper certificate.

What to do next

Once a certificate is issued, an Estate Information Return is due to the Ministry of Finance within 180 calendar days, even if no tax is payable.

Frequently asked questions

Can I probate a will if the witnesses have died?

It may be possible, but it depends on the facts and on what evidence can be put before the court. Rule 74.04 sets the required forms for each situation. A lawyer can tell you what to prepare for your will.

Do I need the original will?

Yes. The original will and any codicil are part of the application, and the original must be attached as an exhibit to a permitted affidavit. Even when you file by email, the original must be filed on paper at the court location.

How long will it take if a witness is missing?

Ontario says applications are typically processed within 15 business days, but it can take longer if documents are missing or a judge must decide an issue. A gap in the witness evidence can add time.

What if the court refuses the application?

The refusal is issued on Form 74O with reasons, or Form 74.1D for a small estate. The reasons tell you what is missing, and a lawyer can help you decide how to respond.
