The basics
A prenuptial agreement is a contract you sign before getting married that spells out what happens to your money and property if the marriage ends. In Canada, lawyers usually call these "marriage contracts" or "domestic contracts." Prenup is just the term that stuck from American TV.
The idea is simple: you and your partner decide now, while you actually like each other, how you'd split things up later. It's not romantic, but neither is fighting over a house in family court.
(Quick note: this article is general information about how prenups work in Canada, not legal advice for your situation. Rules vary by province.)
Who actually gets prenups?
There's this perception that prenups are for tech billionaires or celebrities protecting their yacht collections. That's not reality. Most people who get prenups in Canada are regular people in situations like these:
You own something before marriage. Maybe you bought a condo in Toronto before housing prices went completely insane, or you've been saving in your RRSP for 15 years. Without a prenup, that property could be on the table during a divorce.
You run a business. If you're a co-founder or partner in a business, your spouse could theoretically claim a portion of your share in a divorce. Your business partners probably wouldn't love that. A prenup can keep the business out of it.
Family money is involved. Say your parents plan to leave you the family cottage in Muskoka. In most provinces, inheritances are protected by default, but the rules are complicated. A prenup makes it crystal clear.
Your partner has debt. Student loans, credit card debt, a failed business venture. You might love someone without wanting to be legally tied to their $80,000 line of credit.
You've been married before. Second marriages often involve kids from the first one, existing assets, support obligations. Things get complicated. A prenup helps sort it out.
You just want to talk about money. This one surprises people, but the prenup process forces you to have real conversations about finances, expectations, and values. Some couples find it actually brings them closer.
What goes in a prenup?
Canadian prenups typically cover:
- Who keeps what property (both stuff you owned before and things you buy together)
- How you'd divide assets if you split up
- Spousal support: whether one person would pay, how much, for how long
- What happens to debts
- How you'll handle the family home
- Protection for a business or professional practice
- What happens to inheritances or gifts from family
What can't go in a prenup?
Courts won't enforce everything. These are off-limits:
Anything about kids. Custody, access, parenting time: courts decide these based on the child's best interests at the time, not based on what you agreed to years earlier. Same goes for child support; you can't contract out of your obligations to your children.
Wildly unfair terms. If a prenup basically says "I get everything and you get nothing," a court might toss it out as unconscionable. The agreement needs to be at least somewhat reasonable.
Illegal stuff. Obviously.
Will a court actually enforce it?
Canadian courts generally uphold prenups, but they'll look at a few things:
Was it voluntary? If one person was pressured into signing, especially right before the wedding, that's a problem. Sign it months ahead, not the night before.
Did both people understand it? Each person should get independent legal advice. In Alberta, this is actually mandatory. Elsewhere it's technically optional but strongly, strongly recommended.
Was everyone honest? Both partners need to fully disclose their finances. If you hid assets or lied about debts, the agreement could be voided.
Is it fair? Not perfectly equal, but not absurdly one-sided either. Courts have discretion here.
Timing matters
Don't wait until you're picking out table settings. Start the prenup conversation at least three to six months before the wedding. This gives you time to:
- Actually talk about what you both want
- Gather bank statements, property valuations, business records
- Each hire a lawyer (you need separate ones)
- Go back and forth on drafts
- Sign without feeling rushed
A prenup signed the week of the wedding looks coerced, even if it wasn't.
The provincial wrinkle
Canada doesn't have a single set of family law rules. Each province does its own thing. Ontario's Family Law Act is different from BC's Family Law Act, which is different from Alberta's rules, which are completely different from Quebec's Civil Code.
The practical impact: a prenup that's valid in Vancouver might have issues in Montreal. Make sure yours is drafted for the province where you live (or might live).
Getting started
A prenup doesn't have to cost $5,000 or take six months.
With Prenuply, you can generate a customized template for your province in about 15 minutes. Take that draft to a lawyer for review, and you'll spend a fraction of what you'd pay starting from scratch.
The goal isn't to plan for divorce. It's to take one stressful "what if" off the table so you can focus on actually building a life together.
