In Canada, a marriage contract is a legal agreement that outlines how a couple will handle financial and legal matters during their relationship and in the event of a breakup or death. These agreements are not just for the wealthy, they offer clarity around goals and expectations, reduce future conflict both during the relationship and if it ends, and give both partners a sense of security as you build your life together.
Whether you’re already married, planning a wedding, or living together in a committed relationship, understanding what a marriage contract is and how to make one that fits your family can help you protect your rights and plan your future with confidence.
There are three main types of marriage contracts in Canada: prenups, postnups, and cohabitation agreements. The subject matter of each of these agreements is very similar. The key difference between them is whether or not you plan to get married, are already married, or are living together in a common-law relationship. We’ve set out some key information on each of these types of agreements below.
A prenuptial agreement (or “prenup”) is signed before marriage. In the best case scenario, the conversation about your prenup and what it should include will start well in advance of the wedding, with the agreement being finalized a few months before the wedding date.
A prenup outlines how assets, debts, and spousal support will be handled during the relationship and if the relationship ends. While the stereotype around prenups used to be that prenups are only for the super wealthy, the conversation is shifting and rightfully so! Prenups are increasingly popular among Canadians of all income levels who want to reduce legal uncertainty and build equitable and transparent relationships together. Here’s what you can include in your prenup.
What can a prenup cover?
Prenuptial agreements must be fair and executed properly to be legally binding. We’ll cover that in more detail below.
A postnuptial agreement is signed after a couple is legally married. A postnup can include all of the same details as a prenup. Your marital status is really the key difference between the two.
Couples sign postnups when they didn’t think of or have time to get a prenup before their wedding. Posnups are also used when circumstances change during the marriage. For example, one partner inherits property or starts a business. It makes sense to update your prenup or make a postnup as your life changes. This helps ensure that both partners are still on the same page and that their agreement is still fair and appropriate for your circumstances.
Why choose a postnup?
Postnuptial agreements are less well known in Canada than prenups or cohabitation agreements, but still a powerful legal tool that can be useful for many couples.
A cohabitation agreement is for couples who live together without being married. This is especially important because the laws governing the rights of common law couples vary from province to province. This means that in some provinces, couples living together for a certain amount of time may have similar rights and responsibilities as married spouses while in other provinces, they have significantly less protection when it comes to things like spousal support and property division.
A cohabitation agreement includes all of the same subjects as a prenup or postnup, such as:
If you’re in a common-law relationship, this agreement can offer protection equivalent to that of a prenup or postnup. You can also include a term in your cohabitation agreement that it continues to apply if you later get married.
Anyone in a committed relationship, married or not, can benefit from a marriage contract, especially if:
Even if you’re not wealthy, you have something worth protecting: your peace of mind. Contrary to the old stereotypes, making a prenup, postnup or cohabitation agreement can actually bring you closer as a couple by guiding you through conversations about your goals and expectations for the future, and how to honor each other’s contributions to your family, financial or otherwise.
One of the most common questions is, “What can a prenup cover?” But this applies to all three types of marriage contracts. Here’s what you can include:
However, marriage contracts cannot:
Note on Child Support:
Child support cannot be included in a marriage contract because it is considered the right of the child, not the parents. Canadian courts prioritize the best interests of the child and have determined that the best time to assess what is in a child’s best interests is at the time of separation. Even if both partners agree, a judge likely will not uphold any agreement that attempts to waive or limit child support obligations.
Not every agreement will hold up in court. Several legal requirements must be met in order for a marriage contract to be valid:
An agreement that’s signed under pressure, without proper understanding, or without full financial transparency may not be enforceable down the road.
