Divorce When Your Spouse Won't Sign in Ontario

Your spouse does not need to agree to a divorce in Ontario. They do not need to sign anything. They do not need to cooperate at all. The Divorce Act gives every Canadian the right to end their marriage — one spouse's refusal cannot override the other's legal entitlement to a divorce.

What does change is the procedural path and the timeline. Here is what actually happens when a spouse refuses to participate.

The Default Path: They Ignore the Papers

This is the most common scenario. You file a simple (sole) divorce, serve the respondent through a third party under Rule 6, and the respondent simply does not file a Form 10: Answer within the statutory window.

If they are served in Canada and do not respond within 30 days, they are noted in default by the court registrar. Default strips them of the right to:

• Participate in future steps of the proceeding
• Receive notice of subsequent filings
• Contest the terms of the divorce order

You then proceed with the Stage Two judgment package exactly as you would in any uncontested divorce — file Form 36, Form 25A, and pay the $445 fee. A judge reviews the paperwork at their desk and signs the Divorce Order.

The total timeline is the same as any simple divorce: 4 to 6 months.

Key point: a default divorce is not adversarial. The respondent's silence is treated as non-opposition. The judge still reviews the file, checks child support compliance, and ensures the paperwork is correct — but the respondent's refusal to sign or participate does not prevent the divorce from being granted.

The Contested Path: They File an Answer

If the respondent files a Form 10: Answer, the case becomes contested. This does not mean the divorce will be denied — it means the respondent is disputing something, whether that is the separation date, the support terms, property division, or parenting arrangements.

A contested divorce in Ontario is dramatically different from an uncontested one:

• Cost: $1,500 to $5,000 in professional fees for a simple divorce that transitions to contested (a fully contested case can run from $5,000 to over $80,000), compared to $694 in court fees for uncontested
• Timeline: 6 to 12 months for a contested transition; 12 to 36 months or longer if the case goes to trial (compared to 4 to 6 months)
• Process: case conferences, settlement conferences, potentially a trial

However, even in a contested case, the divorce itself is almost always granted. What gets contested is the ancillary relief — support amounts, property division, parenting time. The marriage breakdown ground (usually one-year separation) is rarely disputed because it is a factual matter.

When You Cannot Find Your Spouse

A different version of the "won't sign" problem: your spouse has moved, changed their phone number, and is not responding to any contact attempt. You cannot serve someone you cannot find, and you cannot proceed without service.

Ontario courts provide two options:

Substituted Service

You file a motion asking the court for permission to serve your spouse through an alternative method — email, social media, publication in a newspaper, or service on a relative or last-known employer. The motion must be supported by a detailed affidavit documenting your search efforts:

• Attempts to contact them at their last known address
• Social media searches
• Calls or visits to their known employer
• Outreach to mutual friends and relatives
• Public directory searches

The court needs to see genuine, documented effort, not a general claim that you "tried to find them."

Dispensing with Service

If even substituted service is impossible — there is no email, no social media, no last-known contacts, and no traceable presence — you can ask the court to dispense with service entirely. This is a high bar. The judge must be satisfied that every reasonable avenue has been exhausted and that further attempts would be futile.

If granted, the divorce proceeds as if service was completed. The respondent is noted in default.

What Your Spouse Cannot Do

Your spouse cannot prevent the divorce by:

• Refusing to sign. A joint divorce requires both signatures, but a simple divorce does not. File as the sole applicant.
• Ignoring the papers. Ignoring the application triggers default, which makes the process easier, not harder.
• Being served outside Canada. If they are served in the United States, the answer period is 60 days; if served elsewhere internationally, it is 90 days, but the divorce still proceeds.
• Hiring a lawyer to fight it. A lawyer can contest ancillary relief, but the divorce itself — the legal dissolution of the marriage — cannot be blocked when the one-year separation ground is met.

What They Can Do

If the respondent does engage, they can:

• File an Answer (Form 10) to contest support, property, or parenting terms
• Request a case conference to negotiate
• Bring a motion to change the venue or procedural terms
• Challenge the claimed separation date

None of these prevent the divorce from being granted. They add time and cost, and they may change the financial or parenting terms, but the marriage will be dissolved.

Practical Advice

If you know your spouse will not cooperate, file a simple (sole) divorce. Do not attempt a joint application — it requires both signatures and stalls immediately if one spouse refuses.

Serve the respondent as quickly as possible after the application is issued. The sooner the answer period starts running, the sooner you can proceed to the judgment stage. If the respondent is uncooperative but locatable, hire a professional process server — the $75 to $200 cost is worth avoiding complications with proof of service.

The Ontario Divorce Filing Process Guide covers both the default path and the contested transition, with the service decision tree, the substituted service motion procedure, and the complete forms sequence for filing when your spouse will not cooperate.
