Key takeaways
  • A Statement of Claim for Divorce must be served on your spouse within one year after it is filed, unless the Court extends the time before that limit runs out.
  • If service is impractical, the Alberta court may order substitutional service on application, supported by an affidavit.
  • If your spouse is served and does not respond, the divorce can often proceed as an uncontested desk divorce decided on paper.

When your spouse has moved out, stopped answering, or left no forwarding address, a divorce can feel stuck before it starts. The court still needs proof that your spouse has been given the divorce papers, so you cannot simply skip that step.

Alberta's court rules do allow for situations where ordinary service is not practical. This article walks through the usual service rules, the court application for another method, and what generally happens next.

This article covers the law of Alberta.

Why your spouse must be served

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. The claim must be served on your spouse, who is the defendant, within one year after the date it is filed. The Court can extend that time, but only on an application filed before the one-year limit expires.

The deadline matters. If the claim is not served within the time or the extended time, no further proceeding may be taken in the action against a defendant who was not served in time.

Ordinary service comes first

A commencement document may be served on an individual by leaving it with the individual, or by sending it by recorded mail addressed to the individual. Service by hand is effective on the date the document is left, and service by recorded mail is effective on the date the individual signs the acknowledgment of receipt. The Court's instructions say you cannot serve the claim personally. A third party must do it, and the Court strongly recommends hiring a process server, who will supply a sworn Affidavit of Service.

Service in Alberta may be proved by an affidavit stating the date and place of service, the method used, and that the person was served. It may also be proved by a written acknowledgment or acceptance of service from the person served. If your spouse is served outside Alberta, the affidavit must also state the real and substantial connection between Alberta and the claim. The Court also publishes separate instructions for service outside Canada under the Hague Service Convention.

If you have even a partial lead on where your spouse is, such as a workplace, a relative or a new city, ordinary service may still be possible. A court will want to know what you tried before it accepts that service is impractical.

Asking the court for substitutional service

If service inside or outside Alberta is impractical, the Court may, on application, order substitutional service. In plain words, that means the court approves a different way of getting the documents to your spouse. The affidavit supporting your application must do the following:

Because you must explain why service is impractical, it helps to keep a record of what you have done to find your spouse. Dates, messages sent, people you contacted and addresses you checked all give the court something concrete to work with. What will be enough depends on the facts, so a lawyer can confirm what to include.

After service: what happens next

A spouse who wants to contest the Statement of Claim for Divorce has 20 days to respond if served in Alberta, 1 month if served elsewhere in Canada, and 2 months if served outside Canada. How that timing works after substitutional service can depend on the wording of the court's order, so check the order carefully.

If the defendant does not respond, the plaintiff uses Noting in Default (Form 14, Rule 3.36(1)) as part of the desk divorce package. The court then decides the divorce on paper, without oral evidence, on the Request for Divorce and supporting affidavits. A spouse who contests nothing need not respond and will receive a copy of the Divorce Judgment by mail. If your spouse does file a Statement of Defence or a Counterclaim for Divorce, the case is no longer an uncontested desk divorce.

If you have dependent children, the court must be satisfied that reasonable arrangements have been made for their support. That can add documents to your package, and it is another reason to get advice when your spouse is missing.

What to do next

Frequently asked questions

Can I hand the divorce papers to my spouse myself?

The Court's instructions say the plaintiff cannot serve the Statement of Claim personally. A third party must do it, and the Court strongly recommends hiring a process server, who will supply a sworn Affidavit of Service.

How long do I have to serve the claim?

A statement of claim must be served on the defendant within one year after the date it is filed. The Court can extend the time on an application filed before the one-year limit expires.

What if I can never find my spouse?

If service is impractical, the Court may order substitutional service on application. If a defendant is not served in the time or extended time allowed, no further proceeding may be taken against that defendant.

Can I start the divorce before we have been separated for one year?

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. Adultery and cruelty are alternative ways to show the marriage has broken down, and they do not need a year of separation first.
