Somewhere between the venue deposit and the dress fitting, a lot of engaged couples start to question whether they should be talking about money before they get married. The answer for most Canadians is yes. But it’s not enough to just talk about money. It’s best to put it in writing as well. Getting a prenup before the wedding is not an admission of doubt at all. In fact, it’s a practical decision that protects both partners. When both parties understand what actually goes into a prenup, the conversation about having one becomes much easier to have.
The Word “Prenup” Is American – Here’s What It’s Actually Called in Canada
In Canada, what people most commonly refer to as a prenup is legally known as a marriage contract or marriage agreement. “Domestic contract” is the broader catch-all term in Canadian legislation, and it includes separation agreements and cohabitation agreements.
The terminology used matters because Canadian family law operates differently from American law. In Ontario, marriage contracts are governed by the Family Law Act. In order for a document to be enforceable, it needs to meet specific legal requirements. To understand what those requirements are, it’s important to get a prenup drafted properly.

What Goes Into a Marriage Contract (and What Doesn’t)
A marriage contract is not only about dividing property when things go wrong. Although this is a significant part of an agreement, its scope is actually broader than what people expect.
A well-drafted agreement can cover a lot more than just property division. It can also cover the division of real estate, handling of business assets upon separation, determining ownership of vehicles and other large-ticket items, how inheritance money will be handled, and spousal support arrangements.
A marriage contract in Canada has limitations, and one of them is determining custody or access to children who are born after the contract is signed. In Canada, child support is non-negotiable. Courts will never uphold any clause that attempts to waive it regardless of what couples have agreed beforehand.
The Inheritance Question Couples Keep Getting Wrong
Inheritance clauses generate the most confusion and the most court appearances out of all the provisions in a typical marriage contract.
Under Ontario’s Family Law Act, inheritance that is received during a marriage is not included in the equalization of net family property. This means that it doesn’t automatically get split 50/50 when couples separate. But this protection disappears when the inherited funds are used to purchase property that both spouses use.
There are couples who ask for a “tracing clause” in their contracts. This provision follows inherited funds into jointly-held assets and keeps them attributed to the original recipient. And yet, family law practitioners generally advise against this approach except when the circumstances are unusually specific. This is because tracing clauses are disproportionately likely to be challenged in court, and so this defeats the purpose of having a contract in the first place.
The best piece of advice that couples can take is to keep inherited assets separated during marriage and document origins carefully. It’s also important to make sure that the marriage contract explicitly addresses how inheritance will be treated before commingling happens.
Spousal Support: The Clause That Keeps Coming Back to Court
Couples often assume that agreeing to waive spousal support in their marriage contract settles the matter permanently. It doesn’t, at least not always.
In Canada, spousal support provisions in domestic contracts are reviewable if there has been a “material change in circumstance.” This is a legal threshold that has to be proven in court, but the bar is lower than people expect. Moving provinces for a new job, having a child, or a serious injury that affects one partner’s earning capacity could all qualify. That doesn’t mean spousal support clauses are useless. They provide structure and a starting point. But they need to be drafted with that reviewability in mind.
A lawyer who understands Canadian family law will draft a spousal support provision that reflects your actual situation: your respective incomes, career trajectories, and any foreseeable life changes. Boilerplate language in this section is where agreements tend to fall apart.
One in Seven Canadian Marriages Now Starts With a Marriage Contract
Canadians are marrying later and arriving at the altar with more individual assets than previous generations. While precise national figures are difficult to pin down, Canadian family lawyers consistently report an upward trend in marriage contracts among couples under 40, driven largely by rising property values. When a Toronto home represents the single largest asset either partner will ever own, “we’ll figure it out” stops being a reasonable position.
That shift has changed who’s getting marriage contracts. It used to be associated almost exclusively with significant wealth disparities: one partner owning a business, a large inheritance at stake, a notable age gap. Those remain common scenarios, but two people in their early 30s buying their first home together in Ottawa or Hamilton are just as likely to have the conversation now. When both partners contributed different amounts to the down payment, the split on separation is not automatically proportional under Ontario law, and most couples don’t know that until it’s too late.
First-time buyers also tend to be marrying later, after years of building their own credit histories, savings accounts, and sometimes investment portfolios. A marriage contract simply documents what each person brought into the marriage and what they’d like to retain some claim to should the relationship end.
The Difference Between a DIY Contract and a Legally Sound One
A lot of software tools and online templates for generating marriage contracts have surfaced over the years. Their appeal lies in the fact that they are inexpensive, fast, and that the process feels manageable. And yet, it’s important to understand that no AI-generated or template-based marriage contract has been tested in a Canadian court.
In this context, legal compliance is not just about using the right words. Instead, it requires that both parties fully disclose their financial situation, that neither party signed under duress or without fully understanding the terms, and that independent legal counsel is available for both parties. A contract can be challenged and set aside without these elements no matter how reasonable they look on paper.
To be safe, it’s best to stick with a collaborative law firm that specialises in domestic contracts. This way, both parties can be walked through the structured process which involves questionnaires, joint and individual meetings, a drafted agreement, and proper execution via witnessed signatures. The whole process is quick enough and will not take more than three months. Plus, it would cost considerably less than what most couples spend on wedding flowers.
When in the Engagement Is the Right Time to Start?
The right time to start thinking about agreements is actually the soonest possible time. In fact, it can even be started a couple of days into the engagement. Trying to negotiate and sign a marriage contract in the final weeks before a wedding is not ideal since this could be argued that one party signed under pressure. This weakens enforceability significantly. It’s important to remember that courts look at the circumstances surrounding the signing as much as they look at the content itself.
Ideally, couples should start the process three to six months before the wedding. This way, both partners have ample time to review financial disclosures without a sense of urgency. Plus, independent legal advice can be taken at each party’s own pace and all decisions end up being thought through properly instead of rushed.
Bringing It Up Without Derailing the Engagement
Most people’s instinct is to avoid the conversation because raising it feels like forecasting failure. That instinct is worth overriding. Proposing a marriage contract is not the same as expressing doubt about the relationship; it’s the same logic as taking out insurance on the home you can’t wait to move into.
Couples who approach it together, as a shared financial planning exercise rather than one person’s demand, tend to find the process far less fraught than they anticipated. The questionnaire process alone which involves disclosing income, debts, and property ownership to each other in a structured setting, surfaces conversations most couples have never had. For many, that turns out to be the point.
A lawyer who takes a collaborative approach, working with both partners together before separating them for individual representation, makes the whole thing considerably more comfortable than the adversarial picture most people have in mind.
The marriage contract conversation is becoming less exceptional and more routine, because the financial stakes of marriage, particularly around housing, have never been higher. Couples who have it early, and have it properly, tend to enter their marriage with more clarity. That’s worth more than most wedding planning decisions combined.
