  • Once served, the respondent has 30 days to file an Answer (60 days if served outside Canada).
  • Ontario family courts take financial disclosure seriously.

Most Ontario divorces are uncontested — both spouses acknowledge the marriage is over, and the paperwork proceeds without a court hearing. But when one spouse disputes the divorce itself, or when there are significant disagreements over property, decision-making responsibility or parenting time for children, or spousal support, the matter becomes contested. The contested divorce process in Ontario is structured but lengthy, and understanding its stages helps you know what to expect at each step.

This article walks through the process from initial application to potential trial, with notes on where most cases settle along the way.

Step 1: The Application Is Filed and Served

The process begins when one spouse (the applicant) files a divorce application at the Superior Court of Justice. In a contested matter, the application typically includes requests for corollary relief — the legal term for claims beyond just the divorce itself, such as:

The application and supporting documents (including any required financial statements) must be personally served on the other spouse (the respondent). This is not optional — a process server or someone other than the applicant must carry out service.

Step 2: The Respondent Files an Answer

Once served, the respondent has 30 days to file an Answer (60 days if served outside Canada). An Answer is the formal document in which the respondent:

If the respondent does not file an Answer, the divorce proceeds as uncontested (on a "noting in default" basis). If they do file an Answer, the matter is officially contested and moves through the stages below.

Step 3: Financial Disclosure

Ontario family courts take financial disclosure seriously. Both parties must exchange:

Courts expect this exchange to happen early. Hiding assets or refusing to disclose is a serious matter that courts address with cost orders and adverse findings. Honest financial disclosure is both a legal requirement and a practical necessity for any negotiated settlement.

Step 4: Case Conference

The case conference is typically the first appearance before a judge in a contested matter. It is not a trial — no evidence is heard and no final orders are made. The purpose is to:

A judge presides but acts as a facilitator rather than a decision-maker at this stage. Both parties (and their lawyers, if represented) attend. It is common to exchange "briefs" — short documents outlining each party's position — before the conference.

Step 5: Motions (If Needed)

Between conferences, either party may bring a motion — a request for the court to make a temporary or procedural order before the final resolution. Common motions in contested divorces include:

Motions add time and cost to the process. They are sometimes necessary, but experienced counsel will advise when a motion is worth bringing versus when it is better to negotiate.

Step 6: Settlement Conference

A settlement conference is a more focused attempt to resolve the case. A judge (different from the one who will hear the trial, if it comes to that) meets with the parties and their lawyers to:

The settlement conference judge can be candid — giving each party a realistic assessment of how the court is likely to rule if the matter goes to trial. This candor is often what prompts settlement. Courts also expect parties to have made genuine settlement efforts before a trial will be scheduled.

Step 7: Trial Management Conference

If the matter has not settled, a trial management conference is held to prepare for trial. The parties and their lawyers confirm:

Step 8: Trial

A family law trial in Ontario is heard by a judge (not a jury). Both sides present their evidence — sworn witness testimony and documentary exhibits — and the judge makes binding decisions on all unresolved issues. After the trial, the judge may deliver a decision orally or in writing (reserved decisions sometimes take weeks or months to be released).

A family law trial is the most expensive and time-consuming outcome. Most lawyers (and courts) work hard to avoid reaching this stage.

The Reality: Most Contested Cases Settle

Here is the important context: the majority of contested Ontario divorce and family law cases settle before trial — often at the settlement conference stage or during negotiations that happen in parallel with the court process. Courts actively encourage settlement. Many families find that collaborative negotiation, mediation, or arbitration resolves their disputes without a judge ever making the final call.

A case being "contested" at the start does not mean it will go all the way to trial. It means there is currently a dispute — and disputes get resolved at many points along the path.

Frequently asked questions

What does a contested divorce cost in Ontario?

Costs vary enormously depending on the issues in dispute, the conduct of both parties, the number of court appearances, and whether expert evidence (business valuators, parenting assessors) is needed. A contested divorce that goes to trial can cost each party tens of thousands of dollars. Settling earlier reduces cost significantly.

Can I represent myself in a contested divorce?

Yes, you have the right to self-represent. In practice, contested divorces involve complex procedural rules, financial analysis, and legal arguments that are difficult to navigate without legal training. Many self-represented parties end up with outcomes they did not anticipate. At minimum, consult a lawyer before each major step.

How is parenting decided in a contested divorce?

Courts apply the "best interests of the child" standard under both the federal Divorce Act and Ontario's Children's Law Reform Act. A judge considers a range of factors — the child's needs, each parent's ability to care for the child, existing relationships, and more. In many cases, a parenting assessor or social worker provides a report to assist the court.

Is mediation available in a contested Ontario divorce?

Yes, and it is often recommended — especially for parenting disputes. Mediation is a voluntary process where a neutral third party helps the spouses reach agreement. A successful mediation can resolve all or most issues before or instead of a trial.
