How Do I File for Divorce in Alberta, Canada?

Filing for divorce in Alberta follows a structured process governed by the federal Divorce Act and provincial procedural rules. Because divorce is federal law in Canada, the legal grounds are identical nationwide, but the paperwork and courts are provincial. Most Albertans pursue a no-fault divorce based on one year of separation.

What Are the Residency Requirements?

Under the Divorce Act, either spouse must have ordinarily resided in Alberta for at least one full year immediately before filing. You can begin separating and gathering documents earlier, but the court will not grant the divorce until residency is satisfied. Learn more about the broader process on our Alberta divorce laws page.

What Are the Grounds for Divorce?

There is only one legal ground—breakdown of the marriage—established three ways:

• One-year separation (by far the most common, used in roughly 90% of Canadian divorces)
• Adultery
• Physical or mental cruelty

For separation, you may live under the same roof and still be considered "separated" if you live separate lives. Review the legal separation glossary term for clarification.

What Are the Filing Steps?

1. Complete a Statement of Claim for Divorce and file it at the Court of King's Bench of Alberta. The filing fee is approximately $260.
2. Serve your spouse with the documents (personal service is required for contested matters).
3. Wait for a response. Your spouse has 20 days (if served in Alberta) to file a Statement of Defence.
4. Request judgment. For an uncontested divorce, submit affidavit evidence and a proposed Divorce Judgment.
5. Receive the Certificate of Divorce, which becomes final 31 days after the judgment.

A detailed step-by-step breakdown is available in our Alberta divorce checklist, and court forms are listed under Alberta divorce resources.

How Long Does It Take and What Does It Cost?

An uncontested divorce typically finalizes in 4–6 months, while contested cases can take a year or more. Statistics Canada data shows the national average age at divorce is around 46 for men and 44 for women. Total costs range from under $1,000 for a simple uncontested filing to $15,000+ for litigated cases involving property or parenting disputes.

What About Children and Property?

In Alberta, the courts address parenting arrangements and decision-making responsibility (the modern terms replacing "custody") under both the Divorce Act and the provincial Family Law Act. Property is divided under Alberta's Family Property Act, generally splitting matrimonial property equally. Because corollary relief—support, parenting, and property—often becomes contested, many people find a family law attorney before filing.
