A contested divorce Ontario occurs when spouses cannot agree on key issues like child custody, support, or property division. The process typically begins with filing an application in court, followed by serving documents to the other party. Both sides present evidence, attend case conferences, and may attempt mediation before going to trial. A judge ultimately decides the unresolved matters based on Ontario family law. This process can be time-consuming and costly compared to an uncontested divorce. Seeking guidance from an experienced lawyer can help protect your rights and improve the chances of a fair outcome in a contested divorce Ontario case.
