Contested divorce is one of the more stressful types of family law matters because it usually means there is no full agreement on key issues. In this 2026 guide, we’ll explain what a contested divorce means in Ontario, how the court process usually works, and what separating spouses should expect when a dispute cannot be resolved right away.
This page is provided for general informational purposes only and does not constitute legal advice. Reading this content does not create a lawyer-client relationship with RPB Law. Family law outcomes depend on the specific facts of each case, and Ontario procedures, timelines, and legal obligations can vary. For advice about your situation, you should speak directly with a qualified Ontario family lawyer.
What is a Contested Divorce?
A contested divorce is a divorce case where one spouse and the other spouse do not agree on one or more important issues, so the matter likely cannot be fully resolved as an uncontested divorce or a purely mutual consent process.
The disagreement may be about the divorce itself, but more often the real dispute involves:
- child support
- spousal support
- child custody
- parenting arrangements
- property division
- assets
- debt
- or the terms of separation.
When that happens, the case can require formal application materials, an Answer, financial statements and supporting documents, sworn affidavit evidence, conferences, motions, and sometimes a trial before a judge in family court.
At RPB Family Law, we explain contested divorce in plain language because many people arrive at this stage overwhelmed by legal terms, court forms, timelines, and legal costs. Our Ottawa family law firm helps clients in Ottawa and across Ontario understand the legal process, protect their rights, and work toward a fair result without unnecessary court involvement where possible.

Contested Divorce vs Uncontested Divorce in Ontario Court Proceedings
The basic difference is whether the parties agree.
- In an uncontested divorce, the spouses are aligned enough that the divorce can move ahead with limited dispute.
- In a contested divorce, one spouse disputes some part of the claim or asks the court for different relief.
Under Ontario’s Family Law Rules, a divorce may be started by an application, answered by the responding party, and worked through the family law court process if the issues are not resolved early.
A person may be “getting divorced” in the broad sense, but the contested part often relates to the main issues around the marriage breakdown, such as:
- child custody (decision-making responsibility)
- parenting rights and parenting plans
- child support under the Federal Child Support Guidelines
- spousal support or alimony-style claims
- family property and debt division
- interim orders about parenting, support, or exclusive possession
- service of process, disclosure, and evidence disputes

What Usually Makes a Divorce Contested?
Most contested files do not become contested because a spouse disputes that the marriage has broken down. In Canada, the more common reality is that separation leads to disagreement over money, children, disclosure, or control of the timeline. The Divorce Act governs divorce and parenting issues for married spouses, while Ontario law and procedure also shape support, property, and court management.
Common reasons a divorce becomes contested include:
Disputes About Child Support, Child Custody, and Parenting Arrangements
If parents disagree about parenting schedules, decision-making, school issues, healthcare, travel, children’s well-being, or support amounts, the court may need to decide. Under section 16 of the Divorce Act, the court must consider only the best interests of the child, with primary consideration given to the child’s physical, emotional, and psychological safety, security, and well-being.
Disputes About Spousal Support
A spouse may seek spousal support after separation, and the other spouse may dispute entitlement, amount, duration, or need. Cases often turn on income, budgets, roles during the relationship, financial statements, and the evidence supporting the claim. Spousal support is one of the most common pressure points in a family law case.
Disputes About Assets, Property Division, and Debt Division
A contested divorce may involve the division of family property, business interests, pensions, the matrimonial home, bank accounts, debt, or other assets accumulated during the marriage. Even where the spouses agree they should be divorced, disagreement on property division can drive litigation and increase legal costs.
Disputes About the Facts or Evidence
Some cases become contested because one spouse says the other has failed to provide complete documents, financial statements, or accurate evidence. Others turn adversarial when one party alleges domestic violence, cruelty, hidden income, or improper handling of children’s schedules and parenting arrangements.
While adultery and cruelty are still legal grounds found in the Divorce Act framework, most Ontario divorces proceed on separation rather than litigating fault grounds because fault-based litigation usually increases complexity without creating a better practical outcome.

How the Legal Process Works in an Ontario Contested Divorce
A contested divorce is still a structured legal process. The exact steps depend on the issues, but the path often looks like this.
1. Starting the Application and Serving the Respondent
One spouse starts the family law case by filing the appropriate divorce application and then serving the other spouse, who becomes the respondent. Service and filing rules are governed by the Family Law Rules.
2. Filing an Answer, Claims, and Supporting Documents
The respondent can file an Answer setting out what is admitted, denied, or contested. In practice, this is where the parties define the legal battlefield: support, parenting, property division, legal separation terms, or requests for court orders. The court file grows quickly from here, especially if there are competing versions of events, financial disputes, or allegations requiring affidavit evidence.
3. Disclosure, Financial Statements, and Evidence
Contested proceedings usually require organized disclosure. That may include income records, tax returns, bank records, business documents, real estate information, pension material, budgets, and sworn affidavits. If the case involves child support or spousal support, financial disclosure is often one of the most important parts of the file.
Ontario court processes and conference requirements are built around parties exchanging materials early enough for meaningful settlement discussions.
4. Case Conference, Settlement Conference, and Interim Orders
In Ontario family law court, many contested cases move through a case conference before motions or trial steps expand. Depending on the issues, the court may later deal with settlement conferences, trial management, or interim relief. Interim orders can address urgent or temporary matters, such as parenting schedules, temporary support, disclosure, or procedural directions, while the case continues.
Strategic Conference and Motion Planning in a Family Law Case
This stage is often when strong preparation changes the file’s trajectory. A clear narrative, reliable documents, focused evidence, and realistic settlement proposals can narrow the issues long before a judge hears a full trial. In our work, that is where careful legal strategy can reduce court involvement, improve negotiation leverage, and protect credibility.
5. Trial and Final Divorce Order
Not every contested case goes all the way to trial, but some do. When the issues cannot be resolved through negotiation, mediation, conference work, or settlement efforts, a judge may hear the evidence and make final decisions. That can result in a final court order covering the unresolved issues, along with the eventual divorce order itself once the legal requirements are satisfied. Most Ontario divorces do not require a full trial, but a trial may be needed when a settlement is not possible.

Do You Need Court, or Can a Contested Divorce Still Settle?
A contested divorce does not automatically mean a courtroom battle from start to finish.
Many contested files begin with serious disagreement and still resolve through negotiation, lawyer-assisted settlement, or mediation before trial. That is one reason it is important to distinguish between a case that is contested and a case that is truly headed for the longest possible litigation track. The court system itself pushes parties toward conferences and settlement efforts before trial whenever appropriate.
At RPB Law, our goal is not conflict for its own sake. We help clients prepare for litigation when needed, but we also look for practical opportunities to resolve the main issues efficiently and responsibly.

How Long Can a Contested Divorce Take?
There is no one fixed timeline. A contested divorce can take months, and more complex files can take much longer, depending on:
- the number of contested issues
- whether children are involved
- the level of financial disclosure needed
- whether expert evidence is required
- court scheduling and hearing availability
- whether the spouses cooperate on documents and settlement steps
Timelines can range from several months to more than a year (complex or high-conflict cases can take longer), especially where property division, child custody, or financial matters remain unresolved.
When Should You Call a Lawyer About a Contested Divorce?
You should speak with a lawyer early if:
- your spouse has started a divorce application, and you need to file an Answer
- there are disagreements about children, support, or family property
- you suspect incomplete financial disclosure
- you are worried about domestic violence, safety, or urgent parenting issues
- you need help understanding court forms, deadlines, or service of process
- you want to pursue a settlement without giving up your legal position
Missing deadlines, using the wrong forms, or filing incomplete material can damage a case before the real issues are even argued.

FAQ About Contested Divorce in Ontario
Is a contested divorce the same as a trial?
No. A contested divorce means there is a dispute. Some contested cases settle through negotiation or mediation before trial, while others require a judge to decide unresolved issues.
Can a spouse contest only child support or parenting arrangements?
Yes. A spouse may agree that the marriage is over but still contest child support, parenting arrangements, custody-related issues, or spousal support. That still makes it a contested family law case.
Do Ontario courts prefer settlement in family law proceedings?
Ontario family law procedure strongly encourages conference work, disclosure, and settlement efforts before trial whenever possible. That does not remove the right to litigate, but it does shape the process.
Does adultery or cruelty always make a divorce contested?
No. Adultery and cruelty are legal concepts under divorce law, but many cases still proceed on separation. What makes the case contested is the presence of unresolved disputes requiring court involvement.
