The honest answer
Prenups in Canada typically cost between $2,500 and $7,500 when you go the traditional route: hiring a family lawyer to draft one from scratch. That's a wide range, and where you land depends on your province, how complicated your finances are, and whether you and your partner agree on terms or spend weeks negotiating.
But here's what most people don't realize: you don't have to do it that way.
What drives the cost up
When you hire a lawyer to create a prenup, you're paying for their time. A straightforward agreement for a couple with modest assets might take 5-10 hours of lawyer time. A complicated one with multiple properties, business interests, and contentious spousal support terms? That could be 20-30 hours or more.
Family lawyers in major cities charge anywhere from $300 to $600+ per hour. In Toronto or Vancouver, senior family lawyers at established firms can charge $700 or more. You can do the math.
The other factor: disagreement. If you and your partner have different views on what should be in the prenup, your lawyers will go back and forth. Every email, every phone call, every revised draft: that's all billable time. A prenup that might have cost $3,000 with aligned partners can balloon to $8,000 or more when there's conflict.
Province differences
Alberta is the most expensive province for prenups because independent legal advice is mandatory for both parties, and each lawyer has to sign an acknowledgment certificate. You're paying for two lawyers no matter what, and both have to do real work, not just a quick signature.
Quebec requires notarization, but notaries generally charge less than lawyers. A standard marriage contract in Quebec might run $1,000 to $2,500 through a notary. Complex situations still get expensive.
Ontario and BC don't require ILA, but any lawyer will tell you to get it. Courts look skeptically at prenups where one or both parties didn't have a lawyer review it before signing.
| Province | Typical Range |
|---|---|
| Ontario | $2,500 - $7,000 |
| BC | $2,000 - $6,000 |
| Alberta | $3,500 - $8,000 |
| Quebec | $1,000 - $4,000 |
These are rough estimates. Simple situations can come in lower; complicated ones can go much higher. (Costs vary by firm and complexity. This is general pricing information, not a quote.)
The ILA question
Even if you don't have a lawyer draft your prenup, you should have one review it before signing.
This is called independent legal advice (ILA), and each partner needs their own lawyer (you can't share).
A straightforward ILA review, where a lawyer reads through a document and explains it to you, typically costs $300 to $800. If they're doing more, like giving detailed advice, suggesting changes, or negotiating with the other side, expect $500 to $1,500 or more.
In Alberta, the mandatory acknowledgment certificate usually costs $500 to $1,000 per person.
The template approach
This is where most couples can save serious money.
Instead of paying a lawyer $4,000 to draft a prenup from a blank page, you start with a comprehensive template that's already customized for your province and situation. Then you pay a lawyer a few hundred dollars to review it and make any needed adjustments.
The math works out like this for an Ontario couple:
Traditional route:
- Lawyer drafts prenup: $3,500
- ILA for Partner 1: $600
- ILA for Partner 2: $600
- Total: $4,700
Template + review:
- Customized template: $50-150
- Lawyer review for Partner 1: $400
- Lawyer review for Partner 2: $400
- Total: $850-950
That's roughly $4,000 in savings. Not by cutting corners on legal protection, but by not paying a lawyer to do work that's already been done.
What about free templates?
You can find prenup templates online for free. We'd caution against this approach.
Free templates are usually generic American documents that don't address Canadian provincial law. They might be missing critical provisions, using the wrong legal terminology, or structured in ways that make them harder to enforce.
More importantly, they're static. They don't adapt to your specific situation: your assets, your province, your preferences around spousal support. You're basically starting with something that needs so much customization that a lawyer would spend as much time fixing it as they would drafting from scratch.
A prenup isn't the place to penny-pinch with sketchy downloads.
Is it worth the money?
Frame it differently: what are you protecting?
If you're bringing a $600,000 condo into the marriage, or a business you've spent ten years building, or expecting a significant inheritance from your parents, the prenup is insurance.
Spending $1,000 (or even $5,000) to protect assets worth hundreds of thousands makes obvious financial sense.
Even if you don't have major assets now, a prenup can save enormous legal fees down the road by making separation simpler if it ever comes to that. Divorce litigation can easily cost $30,000 to $100,000+. A prenup that costs $2,000 upfront and prevents that? Bargain.
How to keep costs down
Agree first, lawyer second. Have real conversations with your partner about what you both want before lawyers get involved. The more aligned you are, the less back-and-forth (and cost) there'll be.
Use a customized template. Starting with a province-specific document that addresses your situation cuts the lawyer's work dramatically.
Organize your finances. Have your asset lists, property values, and debt amounts ready before meeting with a lawyer. Billable hours spent gathering information are billable hours wasted.
Ask about flat fees. Some lawyers offer flat-rate prenup packages. Worth asking.
The Prenuply approach
We built Prenuply specifically to solve the cost problem without sacrificing quality.
For $49, you get a prenup template customized for your province, your assets, and your preferences. The document is professionally formatted and ready for a lawyer to review. Most lawyers can review and finalize a Prenuply document in an hour or two, versus the 10+ hours they'd spend creating one from scratch.
The total cost? Usually under $1,000 all-in, including proper legal review for both partners.
We're not replacing lawyers; they should absolutely review and finalize your document. We're just making sure you're not paying $400/hour for work that doesn't need to cost that much.
