- Once validly signed, a marriage contract remains legally binding on the spouses even after the marriage ends in divorce.
- How you agreed to divide, exclude, or handle net family property typically continues to bind both spouses after divorce.
- Decision-making responsibility, parenting time, and child support are never fully locked in by a domestic contract.
Signing a marriage contract feels like settling the property and support questions once and for all — so it's a fair question whether that agreement keeps working once the marriage legally ends. A marriage contract generally continues to bind former spouses after divorce, but "generally" is doing some work in that sentence: certain terms remain open to a court's review no matter what the contract says.
Divorce itself, under the federal Divorce Act, deals with ending the marriage and any "corollary relief" — support and parenting arrangements. Property and support terms already resolved by a valid marriage contract typically don't need to be revisited in the divorce proceeding. But the two processes are legally distinct, and they interact in specific ways worth understanding before you assume the contract does all the work on its own.
Short Answer: Yes, With Limits
Once validly signed, a marriage contract remains legally binding on the spouses even after the marriage ends in divorce. It doesn't expire the moment a divorce order is granted. What can change is how much control it has over specific issues — particularly anything involving children — where a court retains authority to look past the contract's terms.
What Typically Continues to Apply
- Property division terms. How you agreed to divide, exclude, or handle net family property typically continues to bind both spouses after divorce.
- Spousal support terms. A properly negotiated waiver or formula for spousal support is generally respected, though it isn't automatically beyond challenge.
- Ownership and debt allocation. Agreements about who keeps which asset, or who is responsible for which debt, ordinarily continue to apply as written.
What a Court Can Still Revisit
- Anything involving a child. Decision-making responsibility, parenting time, and child support are never fully locked in by a domestic contract. Courts apply the best-interests-of-the-child test independently of what the parents agreed, and can depart from a contract's child-related terms where the child's circumstances or needs call for it.
- Terms based on incomplete disclosure or unfairness. A court can set aside part of a domestic contract in defined circumstances, such as where one spouse didn't honestly disclose significant financial information before signing.
- Support terms in limited circumstances. Spousal support provisions can, in narrow situations, still be reviewed by a court even where a contract addresses them — particularly where the outcome would be clearly unfair given how the marriage actually played out.
Marriage Contract vs. the Divorce Order
| Marriage Contract | Divorce Order | |
|---|---|---|
| What it resolves | Property and support terms the spouses negotiated | The legal end of the marriage, plus any corollary relief the court decides |
| Who decides the terms | The spouses themselves | A judge (or the spouses, if incorporated into the order) |
| Covers children? | Can address it, but never bindingly | Can include binding parenting and support orders |
| Can be changed later | Only by new agreement or court intervention | Can be varied through a motion to change |
When a Marriage Contract Gets Challenged After Divorce
It's most common for a marriage contract's terms to be challenged around the time of separation and divorce, when the practical stakes of the agreement become real. A spouse who wants to challenge a marriage contract typically needs to point to something wrong with how it was made — not simply that its terms turned out to be unfavourable to them in hindsight.
Frequently asked questions
Do we need to redo our marriage contract as part of the divorce?
Not usually. If it's still valid and addresses the issues in dispute, it typically continues to operate without being re-signed as part of the divorce process itself.
Can a judge just ignore our marriage contract?
Not without reason. Courts generally give effect to validly made domestic contracts, but they retain authority over child-related issues regardless of contract terms, and can intervene on other terms in defined circumstances, such as non-disclosure.
Does divorce cancel a spousal support waiver in a marriage contract?
No — a properly negotiated waiver typically continues to apply after divorce, though it isn't automatically immune from challenge if it was based on incomplete information or would produce a clearly unfair result.
What if our marriage contract doesn't mention divorce at all?
Most marriage contracts are drafted to apply "on separation or divorce," but if yours is silent or ambiguous on a specific issue, that gap is exactly the kind of thing a court, or your lawyers, will need to interpret — worth reviewing well before you rely on it.
