Contested Divorce in Ontario: What to Expect and How to Prepare
When spouses cannot reach an agreement on one or more issues related to the dissolution of their marriage — such as property division, support, or parenting — the divorce becomes contested. A contested divorce is typically more complex, more expensive, and more time-consuming than an uncontested one, but understanding the process can help you navigate it effectively.
What Makes a Divorce Contested?
A divorce becomes contested when the two spouses cannot agree on how to resolve the issues that arise from their separation. This may include disagreements about how to divide property or debts, whether spousal support is owed and in what amount, who will have parenting time with the children, how much child support will be paid, or what decisions will be made about the children’s education, religion, or medical care.

How Does a Contested Divorce Begin?
One spouse files an Application for Divorce at the Ontario Superior Court of Justice. The application is then served on the other spouse, who has the opportunity to file an Answer, agreeing or disagreeing with the claims made, and potentially making their own claims. This is the start of the adversarial court process.
The Conference Process
Ontario family courts require most contested matters to go through a series of case conferences before proceeding to trial. These include a Case Conference, Settlement Conference, and sometimes a Trial Management Conference. These meetings are held before a judge and are designed to narrow the issues in dispute, encourage settlement, and manage the progression of the file.
Disclosure and Discovery
Both parties in a contested divorce are required to provide full financial disclosure. This includes completing a Financial Statement and providing supporting documentation such as tax returns, pay stubs, bank statements, and property valuations. Failure to provide complete and honest financial disclosure can have serious legal consequences.
Motions
During the course of a contested divorce, one or both parties may bring motions to court seeking temporary orders. For example, a motion may ask for temporary spousal support, exclusive possession of the matrimonial home, or a temporary parenting arrangement while the case is ongoing. Motions can add time and cost to the proceedings.
Settlement
The vast majority of contested divorces are ultimately settled without proceeding to a full trial. Settlement can occur at any stage — after conferences, in response to motions, through mediation, or on the steps of the courthouse. Resolving issues by agreement, even at a late stage, is almost always preferable to a trial in terms of cost, time, and emotional impact.
Going to Trial
If settlement cannot be reached, the matter proceeds to trial. At trial, each party presents evidence and arguments before a judge, who then makes binding decisions on all outstanding issues. Family law trials can last days, weeks, or even longer for particularly complex cases. The costs of a full trial can be substantial.
How Long Does a Contested Divorce Take?
A contested divorce in Ontario can take anywhere from one year to several years, depending on the complexity of the issues and the level of conflict between the parties. Court backlogs in Ontario can also contribute to delays. Choosing alternative dispute resolution methods like mediation and arbitration or collaborative family law can significantly shorten the timeline.

Managing the Cost of a Contested Divorce
Legal fees in a contested divorce can escalate quickly. Being organized, responsive to your lawyer, and willing to compromise where reasonable can help manage costs. Many lawyers offer limited scope retainers, where they assist with only specific parts of the case, which can reduce overall expenses.
