Getting Divorced When
You Can't Locate
Your Spouse

A divorce application generally has to be served on your spouse before it can move forward — but what happens when you genuinely don't know where they are? Ontario courts won't let a missing spouse hold your divorce hostage forever, but they do require you to prove you actually tried to find them first. Here is exactly what that process looks like.

Quick Answer

If you can't locate your spouse to serve divorce papers, Ontario courts require proof you made genuine, documented efforts to find them first. Once satisfied, a judge can order substituted service — an alternative method, such as service through a relative or another approach likely to actually reach them — so your divorce can still proceed.

📋 Key Takeaways
  • Normal service means actually delivering the divorce documents to your spouse — you generally can't skip this step just because they're hard to reach.
  • Before allowing an alternative, the court needs genuine, documented efforts — last known address, workplace, relatives, mutual contacts — not just an assertion that your spouse "can't be found."
  • The usual route is a motion for substituted service, asking the court for permission to serve your spouse by another method.
  • Approved alternatives are decided case by case and can include serving a relative, mailing to a last known address, or in some cases email or social media — only where the court believes it will actually reach your spouse.
  • If your spouse truly cannot be found anywhere, rarer last-resort options like service by publication may exist — this is a scenario where legal advice on this specific point is well worth getting.
  • This is a procedural problem only. It does not change your grounds for divorce or touch parenting, support, or property issues.
  • Once service is properly completed and your spouse still doesn't respond, you can generally move toward an uncontested or default-style divorce using the normal next steps.

Why Proper Service Matters

Ending a marriage in Ontario is not just a matter of filing paperwork — the other spouse has to actually know the case exists. The general process of filing for divorce in Ontario assumes a spouse who can be served, whether that happens cooperatively or not: personal or special service at a known address, or service on a lawyer who has agreed to accept it on their behalf. That assumption holds for the vast majority of cases described in our overview of the divorce process in Toronto, which walks through filing, service, and finalization for a spouse who is reachable, even if uncooperative.

This article is about the narrower, harder problem: what happens when your spouse genuinely cannot be found at all — no current address, no response through mutual contacts, nothing. Service is not a formality the court lets you skip; it is the mechanism that protects your spouse's right to know a divorce has been started and to respond if they choose to. The court's job, before allowing any shortcut, is to be satisfied that ordinary service is truly impossible, not simply inconvenient or slow.

⚠️ Inconvenient Is Not the Same as Impossible

A spouse who is avoiding you, who moved without leaving a forwarding address, or who you simply haven't spoken to in years is not automatically "unlocatable" in the court's eyes. You need to show you actually tried the ordinary channels first and that they failed — not just that reaching your spouse would be difficult or unpleasant.

What Counts as "Reasonable Efforts"

Before a court will even consider letting you serve your spouse any other way, it wants to see a real paper trail of attempts to find them — not a single failed text message. The kinds of efforts that typically count include:

  • Attempting service at your spouse's last known home address, even if you suspect they've moved
  • Contacting their last known employer or workplace to confirm whether they still work there
  • Reaching out to known relatives, friends, or mutual contacts who might know their current whereabouts
  • Searching for a current address through any reasonable available means — a change-of-address trail, a mutual acquaintance, a known new city
  • Keeping a record of every attempt — dates, methods, and results — as you go, rather than reconstructing it later from memory

The theme running through all of this is specificity. A court is far more receptive to "I attempted service at 123 Main Street on three dates, called their former employer, and contacted two mutual friends, none of whom have current contact information" than to a general statement that your spouse has disappeared.

Asking for Substituted Service

Once you have genuinely exhausted ordinary service and documented those efforts, the next step is bringing a motion asking the court for an order permitting substituted service — the general term for a court-authorized alternative method of service. Ontario's Family Law Rules allow a judge to permit an alternative method once satisfied that normal service genuinely is not possible, rather than merely difficult.

The motion is typically supported by an affidavit that sets out, in detail, exactly what you did to try to find and serve your spouse, when you did it, and what happened each time. This is the document the judge is actually deciding the motion on, so vague or incomplete efforts are the most common reason a first attempt gets sent back for more evidence.

💡 Pro Tip

Build your affidavit of efforts as you go, not after the fact. A dated log — "called X employer on [date], spoke with HR, confirmed no longer employed there as of [date]" — reads far more credibly to a judge than a reconstructed summary written weeks later from memory.

Some self-represented applicants do bring this motion on their own; our guide to representing yourself in family court in Ontario covers where that tends to work well and where it adds real risk. Because the whole motion turns on the court's judgment of whether your efforts were genuinely reasonable, many people also bring in a family lawyer at this stage specifically to help frame the affidavit and propose a method the court is likely to accept.

Alternative Methods Courts May Allow

There is no single standard substitute — the court decides, case by case, what is actually likely to reach your particular spouse given what you know about them. Depending on the circumstances, a judge may permit:

  • Service on a close relative on your spouse's behalf, where that relative is in contact with them
  • Mailing documents to a last known address, often combined with a second method for added reliability
  • Service by email or social media, in some cases, where the court is satisfied that account is one your spouse is actually still using and likely to see
📌 Not a Routine Default

Email or social-media service is sometimes described online as if it's automatically available. It isn't. A judge authorizes it only in appropriate cases, after being satisfied that method will actually reach your spouse — it's a court-approved alternative, not something you can simply decide to use on your own because it's convenient.

🧩 Example

Someone documents three failed attempts at a spouse's last known address, confirms through a sibling that the spouse now lives out of province but won't share the address, and shows the spouse remains active on a social media account the sibling confirms is genuinely theirs. A court may find that combination of documented efforts and a reliable alternative channel sufficient to permit substituted service through that account, sometimes paired with notice to the sibling as well.

When Your Spouse Truly Cannot Be Found

Occasionally, even after genuine efforts, there is no relative in contact, no working address, no social media presence, and no realistic alternative method likely to reach your spouse at all. In those rarer situations, further last-resort options — such as service by publication in some cases — may exist. This is one of the more procedurally involved paths available, and it is not something to improvise based on a general description; it is specifically a scenario where getting legal advice on your exact facts is worth it before you proceed.

If your spouse's whereabouts are unknown partly because the marriage or the separation involved another country — for example, you married abroad before relocating to Ontario — our guide on getting divorced in Toronto after marrying abroad covers the related issues that can come up alongside a cross-border locating problem, such as documentation about the marriage itself. If the spouse you cannot locate originally came to Canada through spousal sponsorship, see our separate guide to divorce and sponsorship breakdown for the immigration-status questions that can come up alongside the service problem.

After Service Is Completed

Once service has been properly completed — by whatever method the court actually authorized — the clock starts on your spouse's time to respond. If nothing comes back, you can generally move the file toward an uncontested, default-style divorce, following the same next steps as any other case where the other side isn't participating. Our detailed divorce timeline guide walks through how long each remaining stage typically takes once service is behind you.

It is worth remembering that getting past the service problem does not, by itself, finish the divorce. The remaining steps are the same ones every applicant goes through, ending with a divorce order that becomes final 31 days later, after which you can request a divorce certificate — the document you will eventually need for things like remarriage or updating your legal status with banks and government agencies.

Common Mistakes

The errors that come up repeatedly in these cases are avoidable ones:

  • Telling the court your spouse "can't be found" without any documented attempts behind the statement
  • Trying only one method once, then giving up and assuming that is enough to ask for an alternative
  • Assuming email or social-media service is automatically allowed, rather than something a judge specifically has to approve
  • Moving forward with an alternative method without court permission at all, which risks the entire divorce being challenged later for improper service
  • Losing track of dates and details of earlier attempts, then struggling to reconstruct a credible affidavit months later

Many of these mistakes come from self-represented applicants navigating the motion process without guidance; see our broader guide on representing yourself in Ontario family court for where that approach tends to hold up and where it tends to backfire.

Getting Help With a Hard-to-Serve Spouse

A spouse you can't locate is one of the more procedurally tricky problems a divorce application can run into, precisely because the court is exercising judgment about whether your efforts were genuinely reasonable and whether your proposed alternative will actually work. Getting this step right the first time avoids months of delay from a rejected motion. Our Toronto divorce lawyers regularly help clients build the documented record a court wants to see and choose a method of service that is actually likely to succeed.

Frequently Asked Questions

Can I get a divorce in Ontario if I can't find my spouse?

Yes. A missing spouse does not permanently block a divorce. You first have to show the court you made genuine, documented efforts to locate and serve them. Once a judge is satisfied that ordinary service genuinely isn't possible, the court can authorize an alternative method of service so the case can move forward.

What is "substituted service" in Ontario family law?

Substituted service is the general term for a court-authorized alternative method of serving court documents when the usual method — delivering them to your spouse personally, or to their lawyer — isn't realistically possible. Ontario's Family Law Rules allow a judge to permit an alternative method once satisfied that genuine efforts at ordinary service have failed.

What counts as a reasonable effort to find my spouse before asking the court for help?

Courts want to see specific, documented attempts: checking the person's last known home address, contacting their last known workplace or employer, reaching out to known relatives or mutual contacts, and searching for a current address through any reasonable available means. A bare statement that your spouse "can't be found" is not enough on its own.

Can I serve my spouse by email or social media?

Possibly, but it isn't automatic. A court may permit email or social-media service as part of a substituted service order, but only where it is satisfied that method is actually likely to reach your spouse — for example, an account they are known to still be using. It is an alternative a judge authorizes in appropriate cases, not a routine default you can simply choose.

How do I actually ask the court for substituted service?

You generally bring a motion asking the court for an order permitting an alternative method of service, supported by an affidavit setting out, in detail, the efforts you made to locate and serve your spouse and why you believe those efforts were reasonable but unsuccessful. The more specific and documented your affidavit, the stronger the motion.

What if my spouse moved to another country and I don’t have a current address?

The same basic framework applies — you document your efforts to locate them, including any international angle, such as a last known foreign address or contacts who might know their whereabouts, and ask the court for an appropriate method of service. If your marriage itself took place outside Canada, our guide on divorcing after marrying abroad covers the related issues that can come up alongside a locating problem.

Is there a point where service by publication or some other last-resort method is used?

In rarer cases where a spouse genuinely cannot be located or reached by any practical method, further last-resort options such as service by publication may be available in appropriate circumstances. This is one of the more procedurally involved paths, so it is worth getting legal advice specifically on your situation before pursuing it.

Do I need a lawyer to get an order for substituted service?

Not strictly — some self-represented applicants do bring these motions themselves. But because the court is assessing whether your documented efforts were genuinely reasonable, having help preparing a thorough affidavit and choosing the right proposed method can make the difference between a motion that succeeds the first time and one that gets sent back for more evidence.

What happens once my spouse is finally served and still doesn't respond?

Once service is properly completed — by whatever method the court authorized — and the required response time passes with no response, you can generally proceed toward an uncontested or default-style divorce, following the same next steps as any other divorce application that isn't being contested.

Does not being able to find my spouse change the grounds for my divorce?

No. Not being able to locate your spouse is purely a service problem — a question of how the court documents get to them. It has no effect on the substantive grounds for divorce, such as your separation date, and no effect on parenting, support, or property issues, which are decided separately.
