- An uncontested divorce means both spouses agree on the divorce itself and every related issue — support, property, and parenting. A contested divorce means at least one issue remains disputed.
- Ontario recognizes three legal grounds for divorce under the federal Divorce Act: one year of separation, adultery, or cruelty. Over 90% of divorces proceed on the separation ground.
- An uncontested (often called a joint) divorce can be finalized in as little as 4 to 6 months, largely on paper, without a single court appearance.
- A contested divorce proceeds like full civil litigation — pleadings, disclosure, conferences, and potentially trial — and can take 12 to 24+ months.
- A case does not have to stay in one category — a contested divorce can become uncontested at any point if the parties reach a full settlement.
- The distinction is less about how the marriage ended emotionally and more about whether every legal issue has been resolved on paper before the application is filed.
The Short Answer
An uncontested divorce means both spouses agree — on the divorce itself and on every related issue, including parenting, support, and property. A contested divorce means at least one of those issues remains genuinely disputed, requiring the court to help resolve it. The label is not about how amicable the separation felt emotionally; it is a procedural description of whether everything has been agreed to on paper before the application is filed.
This distinction matters enormously, because it is the single biggest factor in how long your divorce takes and how much it costs. This guide breaks down exactly what separates the two paths, and how one can turn into the other along the way.
What Makes a Divorce “Uncontested”?
A divorce is uncontested when both spouses agree on:
- That the marriage has broken down and the legal ground for divorce is met
- Parenting arrangements for any children, if applicable
- Child and/or spousal support, if applicable
- Division of property and debts
When every issue is resolved — often through a separation agreement negotiated in advance — the spouses can file a joint divorce application, which typically proceeds without a court appearance.
An uncontested divorce can still involve a lawyer, mediation, or negotiation to reach that agreement — “uncontested” describes the state of the file when it is filed with the court, not necessarily how easily the parties got there.
What Makes a Divorce “Contested”?
A divorce is contested when the spouses cannot agree on one or more issues, and the court must become involved to help resolve the dispute. Common contested issues include:
- Parenting arrangements — decision-making responsibility and parenting time
- Child or spousal support — the amount, duration, or whether it is owed at all
- Property division — valuing and dividing assets such as the matrimonial home, pensions, businesses, and debts
A couple agrees on parenting time and child support but disagrees sharply on how to value one spouse's small business for equalization purposes. Even though most issues are settled, this single disputed issue makes the matter contested until it is resolved.
Legal Grounds for Divorce in Ontario
Every divorce in Canada, including Ontario, is granted under the federal Divorce Act, which recognizes three grounds:
| Ground | What It Requires | How Common |
|---|---|---|
| Living separate and apart for one year | The spouses have lived apart (which can sometimes include living under the same roof) for at least one year before the divorce is granted | Used in the vast majority of divorces |
| Adultery | One spouse committed adultery — must be established as fact | Rare |
| Cruelty | Physical or mental cruelty that makes continued cohabitation intolerable | Rare |
Because the separation ground does not require proving fault, most couples — even those with a contested divorce over other issues — rely on it, and simply wait out the one-year separation period while other issues are resolved.

The Contested Divorce Process
A contested divorce follows a process much closer to standard civil litigation, layered on top of the divorce application itself:
- Application and response — one spouse applies, and the other files an answer disputing specific issues.
- Financial disclosure — both spouses exchange financial statements and supporting documents.
- Case conferences — early court appearances to narrow the issues and set a process going forward.
- Settlement conferences — a judge helps the parties explore resolution before trial.
- Trial — if no settlement is reached, a judge decides the outstanding issues after hearing evidence.
Contested family litigation in Ontario is not a quick process. Realistic expectations matter — see our guides on divorce timelines and divorce costs for what a contested matter typically involves.
Uncontested vs. Contested: Side-by-Side Comparison
| Factor | Uncontested Divorce | Contested Divorce |
|---|---|---|
| All issues agreed? | Yes | No — at least one disputed |
| Court appearance required? | Usually none | Multiple, potentially including trial |
| Typical timeline | 4–6 months | 12–24+ months |
| Typical cost | Lower | Significantly higher |
| Formal financial disclosure required? | Only what supports the agreement | Full, formal exchange required |
| Predictability of outcome | High — you control the terms | Lower — a judge may decide unresolved issues |
Can a Contested Divorce Become Uncontested?
Yes — and it happens often. If the spouses reach a full settlement on every outstanding issue at any stage — whether through direct negotiation, a lawyer-assisted settlement, mediation, or a court settlement conference — the matter can shift to an uncontested footing from that point forward, avoiding the time and expense of trial.
Even a matter that starts contested benefits from resolving as many issues as possible early. Narrowing a dispute down to a single genuinely contested issue — instead of three or four — can dramatically reduce the time and cost of reaching a final resolution.
Common Myths
Myth: “Contested means we will definitely go to trial.”
False. Most contested family law matters in Ontario settle before trial. “Contested” describes the starting point, not the inevitable outcome.
Myth: “We need a reason like adultery to get divorced.”
False for the vast majority of cases. The one-year separation ground requires no fault to be proven and is used in the overwhelming majority of Ontario divorces.
Myth: “An uncontested divorce means we can't get legal advice.”
False. Many uncontested divorces are reached with the help of lawyers negotiating a separation agreement on each spouse's behalf — “uncontested” just means that agreement is reached before the application is filed.
Which Path Applies to You? A Quick Checklist
- Do you and your spouse agree on parenting arrangements, if you have children together?
- Do you agree on support — whether it is owed, and how much?
- Do you agree on how to divide property and debts, including the matrimonial home?
- Has it been at least one year since you separated, or do you have grounds based on adultery or cruelty?
If you answered “yes” to the first three, you likely have — or are close to having — an uncontested divorce. If any answer is “no” or “we're not sure,” your matter may currently be contested on that specific issue, which is worth addressing directly rather than assuming it will resolve itself.
Do You Need a Lawyer for an Uncontested Divorce?
Not necessarily, if every issue is already genuinely resolved and documented. However, a lawyer can be valuable even in an uncontested matter to confirm that your separation agreement properly addresses support and property in a way that will hold up, and that the divorce application itself is completed correctly to avoid delays or rejection by the court.

Frequently Asked Questions
An uncontested divorce means both spouses agree on the divorce itself and on every related issue — parenting arrangements, support, and division of property. It can typically proceed as a joint application without a court appearance. A contested divorce means at least one of those issues remains disputed, requiring the court to resolve it through a full litigation process that can include disclosure, conferences, and potentially a trial.
Yes, technically. Ontario divorces are granted under the federal Divorce Act, which recognizes three grounds: living separate and apart for at least one year, adultery, or cruelty. In practice, the overwhelming majority of divorces proceed on the one-year separation ground, since it does not require proving fault.
Yes, particularly for a straightforward uncontested divorce with no other disputed issues. Many people complete a joint divorce application without a lawyer. That said, a lawyer can help ensure your separation agreement (if any) properly addresses support and property before you finalize the divorce, since the divorce itself does not resolve those issues unless they are included.
An uncontested, joint divorce application can often be finalized in about 4 to 6 months, largely through paperwork, without a court appearance. See our dedicated guide on Ontario divorce timelines for a full breakdown of each stage.
A fully contested divorce, involving disputed parenting, support, or property issues, proceeds like standard family litigation and commonly takes 12 to 24 months or longer, depending on how many issues remain unresolved and current court scheduling.
Not necessarily. Most contested family law matters in Ontario settle before trial, often through negotiation, mediation, or a settlement conference. "Contested" simply describes the starting point — that at least one issue is disputed — not the inevitable outcome.
Yes. If the parties reach a full settlement on all outstanding issues at any point — whether through negotiation, mediation, or a settlement conference — the matter can proceed to an uncontested divorce from that point forward, avoiding the time and cost of trial.
Not necessarily. Some couples separate amicably but still have a genuine, good-faith disagreement over one specific issue — such as how to value a business or how to split parenting time — that requires a court process to resolve, without the relationship itself being adversarial.
The most common disputed issues are parenting arrangements (decision-making and parenting time), child or spousal support amounts, and division of property, including the matrimonial home, pensions, and business interests. A divorce can be contested over just one of these issues even if the parties agree on everything else.
Generally, yes, significantly. An uncontested divorce avoids the cost of prolonged litigation — document exchange, conferences, and potentially trial — that drives up legal fees in contested matters. See our dedicated guide on the cost of divorce in Ontario for a detailed breakdown.
A spouse cannot indefinitely block a divorce once the legal grounds are met, but they can turn it into a contested matter by disputing other issues, such as parenting or property division, which must then be resolved before the divorce is finalized (or the divorce can sometimes be granted separately, with other issues resolved afterward, depending on the circumstances).
A joint divorce application is filed by both spouses together, confirming they agree on the divorce and any related terms. It is generally the fastest and least expensive path to an uncontested divorce, since the court does not need to resolve any disputed issue between the parties.
