Key takeaways
  • You can start an Alberta divorce before the year of separation is complete, but you cannot ask for the Divorce Judgment until the year has passed.
  • Adultery and cruelty are alternatives to the one-year separation, so neither needs a year of separation first.
  • A divorce generally takes effect on the thirty-first day after the judgment is rendered, but a pending appeal can delay that date.

You separated recently, and someone has told you that you must wait a year to divorce. The answer is a little more nuanced than that. The year matters, but it matters at a particular point in the process.

This article explains what you can do early, what has to wait, and when adultery or cruelty may be used instead of the one-year separation. Your facts matter a great deal here, so a lawyer can confirm how this applies to you.

This article covers the law of Alberta.

What the one-year rule actually requires

In Alberta, the only ground for divorce is a breakdown of the marriage. One way to prove it is that you and your spouse have lived separate and apart for at least one year immediately before the divorce is decided, and were living separate and apart when the proceeding started.

So the year is measured up to the time the divorce is decided, not necessarily up to the day you file. You do need to be living apart when you start.

Starting before the year is up

A spouse who relies on one-year separation can start the divorce before the year is up, but cannot ask for the Divorce Judgment until the year has passed. That fits the wording of the Divorce Act, which requires the year to be complete when the divorce is determined.

Starting early can let you move paperwork along, such as serving your spouse. A claim must be served within one year after the date it is filed, unless the Court extends the time on an application made before that year runs out. Separately, you must meet the residence test: one spouse must have been habitually resident in Alberta for at least one year immediately before the proceeding starts.

The Court of King's Bench of Alberta has sole jurisdiction over divorce in Alberta, and the Court of Justice cannot grant one. A one-spouse divorce starts with the Statement of Claim for Divorce, Form FL-01, under Rule 12.7 of the Alberta Rules of Court. If you and your spouse agree, the application can instead be made by both of you, using the Joint Statement of Claim for Divorce, Form FL-08.

In a one-spouse divorce, the Court's instructions say you cannot serve the Statement of Claim personally. A third party must do it, and the Court strongly recommends a process server, who will supply a sworn Affidavit of Service. In a joint divorce both spouses are applicants, so no service on a defendant is needed. A served spouse who wants to contest has 20 days to respond if served in Alberta, 1 month if served elsewhere in Canada, and 2 months if served outside Canada.

Adultery and cruelty as alternatives

Breakdown can also be established if the other spouse has committed adultery since the marriage, or has treated you with physical or mental cruelty that makes continued cohabitation intolerable. These grounds are alternatives to the one-year separation, and you are not required to wait a year before relying on them.

There are practical limits. The Court's desk-divorce instructions note that for adultery, the other spouse must in most cases be willing to sign an affidavit admitting it. Cruelty must be of a kind that makes continuing to live together intolerable. Because these grounds depend on proof and on your spouse's response, many people still choose to rely on separation. A lawyer can help you weigh that choice.

Living apart under one roof and brief reconciliations

What to do next

Once the Divorce Judgment is signed in Alberta, you wait 31 days and then request the Certificate of Divorce through the online request form on the Court of King's Bench website.

Frequently asked questions

Can I file for divorce in Alberta after only a few months apart?

You can start the proceeding before the year is up if you rely on one-year separation, but you cannot ask for the Divorce Judgment until the year has passed. You must also be living separate and apart when you start.

Do I have to wait a year if my spouse committed adultery?

No. Adultery is an alternative to the one-year separation, and the spouse who alleges it is not required to wait a year. In most cases the other spouse must be willing to sign an affidavit admitting it for a desk divorce.

Does a short reconciliation restart the one-year clock?

Not necessarily. The separation period is not interrupted if you resumed living together for no more than ninety days in total with reconciliation as the primary purpose.

When is the divorce final?

A divorce generally takes effect on the thirty-first day after the judgment granting it is rendered. A court may make it take effect earlier if it finds special circumstances and the spouses agree and undertake that no appeal will be taken, or any appeal has been abandoned. If an appeal is pending at the end of the 31 days, the divorce takes effect only once the time to appeal the appeal decision has run out, unless it is voided on appeal.
