A Step-by-Step Guide for Spouses

Going through a divorce in Ontario can feel overwhelming—but understanding the process can ease stress and help you make informed decisions. Whether your divorce is contested or uncontested, knowing the legal steps, timelines, and documentation involved is essential.

This guide outlines the key stages of the divorce process in Ontario, including who can file, required forms, timelines, and legal support options.

Legal Grounds for Divorce in Ontario

To be eligible to file for divorce in Ontario, your marriage must meet one of the following legal grounds under the Divorce Act:

  • You and your spouse have lived separately for at least one year
  • Your spouse has committed adultery
  • Your spouse has subjected you to physical or mental cruelty

✅ Most divorces in Ontario are filed on the ground of one-year separation. You may still live in the same home and be considered separated if you lead independent lives.

3. File Your Divorce Application

Submit your forms to the Superior Court of Justice in your municipality and pay the court filing fee (~$669 as of 2025).

4. Serve the Divorce Papers

If it’s not a joint application, one spouse must serve the documents to the other and file an Affidavit of Service with the court.

5. Wait for Court Review and Divorce Order

The court will review the documents and issue a Divorce Order. The divorce becomes final after 31 days.

Do You Need to Go to Court?

Uncontested divorces can often be finalized without a court appearance. Contested divorces may involve multiple court dates to resolve parenting, financial, or property disputes.
