Key takeaways
  • An uncontested divorce is decided on paper, using an affidavit (Form 36) as the evidence.
  • The court will not grant a divorce without the marriage certificate and a Central Registry of Divorce Proceedings report.
  • If you have no marriage certificate, the court can still grant the divorce if it accepts the explanation in your affidavit.

If your divorce is uncontested, no one usually appears before a judge. Instead, the judge reads your paperwork, so what you put in it matters. Missing or unclear documents are a common reason files are sent back.

This article walks through the Form 36 affidavit, how to prove your marriage, and the other documents the court needs before it grants the order.

How an uncontested divorce is decided

An uncontested divorce is decided on paper. The clerk prepares a Certificate of Clerk (Divorce) (Form 36A) and presents the file to a judge. The judge may grant the divorce as drafted, return the papers for correction, or grant it with changes or refuse it after giving the applicant a chance to respond. Rule 36 does not require anyone to attend in person.

What the Form 36 affidavit must cover

The evidence is an affidavit, Form 36: Affidavit for Divorce. It must confirm the information in the application, prove the marriage if no certificate is filed, and prove any earlier divorce or death of a spouse. It must also give the child support arrangements and financial information, and any other information necessary for the court to grant the divorce.

The child support information matters because the court must be satisfied that reasonable arrangements have been made to support any children of the marriage. If they have not, it delays the divorce.

Who swears the affidavit

An affidavit is sworn evidence, so make sure everything in it is accurate and complete.

Proving the marriage and other required documents

The court will not grant a divorce until it has the marriage certificate (or marriage registration certificate) and a report from the Central Registry of Divorce Proceedings on any earlier divorce cases.

If you do not have the marriage certificate, the court can grant the divorce without the original if it accepts the explanation given in the Form 36 affidavit. A certificate that is not in English must be translated by a certified translator.

The applicant also files three copies of a draft Divorce Order (Form 25A) and stamped envelopes for each party. If support is included, an extra copy and two draft support deduction orders are also needed.

Frequently asked questions

Do I have to go to court for an uncontested divorce?

Rule 36 does not require anyone to attend in person, because an uncontested divorce is decided on paper. If an answer is filed, the case is contested and parties attend conferences.

What if I lost my marriage certificate?

The court can grant the divorce without the original if it accepts the explanation in your Form 36 affidavit. A certificate not in English needs a certified translation.

Do we each need our own affidavit in a joint divorce?

Ontario's joint divorce checklist says each spouse completes a separate Form 36.

What can the judge do with my papers?

The judge may grant the divorce as drafted, return the papers for correction, or grant it with changes or refuse it after giving the applicant a chance to respond.
