Do You Have to Be Separated for One Year Before Divorce in Alberta?

In most cases, yes. The one-year separation period is by far the most common ground for divorce in Alberta. But it is not the only option, and the rules around how that year works are more nuanced than most people realize.

The One-Year Separation Rule

Under Section 8 of the federal Divorce Act, divorce can only be granted on the sole ground of "breakdown of the marriage." The most common way to prove this is by demonstrating that you and your spouse have lived "separate and apart" for at least 12 consecutive months.

You can file your Statement of Claim with the Court of King's Bench before the 12 months are complete — many people file early to get the paperwork moving. But the court cannot grant the final Divorce Judgment until the full year has passed from the date of separation.

Living Separate Under the Same Roof

Financial reality means many separating couples cannot afford to maintain two households immediately. Alberta law recognizes this. You can live in the same home during the separation period, as long as you can demonstrate you are living separate lives.

Evidence that courts look for:

• Separate bedrooms
• No shared meals or domestic routines
• Independent financial accounts
• No joint social activities
• Each spouse managing their own household responsibilities

If your separation is challenged, you may need to provide sworn evidence of these arrangements in your Affidavit of Applicant.

The 90-Day Reconciliation Window

The Divorce Act includes a practical provision: spouses can attempt reconciliation and resume cohabitation for up to 90 days during the one-year separation period without resetting the 12-month clock.

If the reconciliation attempt fails and you separate again within 90 days, the original separation date stands. If you cohabit for more than 90 days, the clock resets and a new 12-month period begins from the date you separate again.

When You Do Not Need to Wait a Year

Two alternative grounds allow you to file for an immediate divorce without waiting for the separation period:

Adultery. If your spouse has committed adultery, you can seek a divorce without any separation period. The adultery must be proven to the court's satisfaction — typically through a sworn affidavit from the spouse who committed it. You cannot rely on your own adultery as a ground. Due to the evidentiary burden and potential for conflict, this ground is uncommon in practice.

Cruelty. If your spouse has subjected you to physical or mental cruelty severe enough to make continued cohabitation intolerable, you can file immediately. This requires detailed, objective evidence of the cruelty and its impact. Like adultery, cruelty claims are adversarial and expensive to prove, which is why the vast majority of Alberta divorces proceed on the no-fault separation ground.

Filing Early

You do not have to wait until the one-year separation is complete to start the divorce process. Many applicants file their Statement of Claim a few months into the separation to:

• Begin the Ottawa Central Registry clearance process (which takes 4–6 weeks)
• Start the service and response timeline
• Complete mandatory requirements like the Parenting After Separation course (if children under 18 are involved)

By filing early, you can have much of the administrative work done before the 12 months are up, so the desk divorce package can be submitted shortly after the one-year mark.

Tracking Your Dates

Getting the separation date right matters — it affects when you can submit your desk divorce package, when the two-year property division limitation period under the Family Property Act starts, and how child support calculations are structured. The Alberta Divorce Filing Process Guide includes a deadline tracker that helps you manage these dates from day one.
