Challenging a separation agreement
June 27, 2025

A well drafted separation agreement can be a great guiding document for separated spouses or partners going forward. However, some separation agreements can be set aside by a court. Some of the common reasons why a separation agreement can be set aside include:
- If a party failed to disclose all their significant assets or debt and the court determines that proper financial disclosure was not made;
- If a party failed to understand the nature or consequences of the separation agreement;
- If a party did not have independent legal advice before signing the separation agreement;
- If the court finds that the terms in the separation agreement are unfairly one-sided or unjust, namely unconscionable;
- If a party was forced or coerced into signing the separation agreement;
- If one party improperly influenced the other’s decision to enter into the separation agreement;
- If a party made false statements or intentionally concealed information during the negotiation process;
- If there was a genuine and significant mistake by one or both parties about a fundamental aspect of the separation agreement;
- If the separation agreement was not signed or witnessed;
- If the separation agreement deals with child-related issues, the court will prioritize the best interests of the child and may set aside provisions in a separation agreement that are deemed not to be in the child’s best interests;
- In some cases, a separation agreement may be set aside if it goes against public policy or is otherwise deemed harmful to society.
