A prenup in Canada usually involves two separate costs: preparing the agreement and having each partner receive independent legal advice. Published flat fees checked on August 3, 2026 ranged from $1,500 to $2,300 plus tax for straightforward drafting by one lawyer, while one Ontario firm listed independent legal advice from $750 plus tax. The second lawyer, negotiation, revisions and complex assets are additional, so the total legal cost commonly starts in the low thousands and can rise substantially.
Online drafting can reduce the document-preparation portion of the bill, but it does not replace province-specific advice or the need for separate lawyers where independent advice is required or appropriate.
Prenup cost in Canada at a glance
| Cost component | Published or typical planning amount | What it covers |
|---|---|---|
| Lawyer drafting | Selected published flat fees from $1,500 to $2,300 plus tax | Intake, advice to one partner, drafting and the revisions included in that firm's scope |
| Independent legal advice | One published Ontario example starts at $750 plus tax | A separate lawyer reviews the agreement and advises the other partner |
| Online guided draft | Provider price, plus separate legal review | Organizes financial information and produces a working draft before lawyer review |
| Complex or negotiated agreement | Quote required | Businesses, trusts, multiple properties, support negotiations, tax issues or extensive revisions |
These are examples from publicly posted Canadian legal-service fees, not a national tariff or a quote. Ask each lawyer what the fee includes, whether revisions are capped, and whether tax and disbursements are extra.
What changes the total cost
The largest cost drivers are the amount of legal work and negotiation required. A lawyer may need more time when either partner has:
- a corporation, professional practice, partnership or family business
- several properties, a cottage or property in another country
- a trust, expected inheritance or significant family gifts
- pensions, stock options, restricted share units or complex compensation
- proposed limits on spousal support
- incomplete financial records or disagreement about values
- requested changes from the other partner's lawyer
Timing matters too. Starting shortly before a wedding can create pressure and leave less time for disclosure, advice and revisions. Beginning early gives both partners more room to negotiate and choose their own lawyers.
Published Canadian fee examples
The following prices were publicly displayed when checked on August 3, 2026. They show why a single national average can be misleading.
| Published provider | Publicly listed fee | Scope shown on the provider's page |
|---|---|---|
| BTL Law, Ontario | $1,500 plus HST | Basic prenup drafting for a straightforward agreement |
| Solvine Law, Ontario | $2,300 plus HST | Flat-fee marriage contract drafting package |
| Oathstone Law, Ontario | From $2,000 plus HST | Drafting and advice for one party |
| Oathstone Law, Ontario | From $750 plus HST | Independent legal advice for a domestic contract |
| Cube Law, British Columbia | $1,500 plus tax | Fixed-fee prenup drafting with one revision |
Public prices can change. They also do not necessarily include the other partner's lawyer, extra negotiation, valuation, tax advice or work outside the listed package.
How province affects prenup cost
Family law is provincial, so the process and professional help are not identical across Canada.
| Province | Important process point | Detailed cost guide |
|---|---|---|
| Ontario | Marriage contracts must be written, signed and witnessed. Section 56 of the Family Law Act identifies circumstances in which a court may set aside a domestic contract. | Ontario prenup cost guide |
| British Columbia | Property agreements are generally written and witnessed. Sections 92 and 93 of the Family Law Act address property agreements and when a court may set one aside. | BC prenup cost guide |
| Alberta | Sections 37 and 38 of the Family Property Act set specific requirements for enforceable agreements that opt out of the statutory property rules, including separate lawyer acknowledgements. | Alberta prenup cost guide |
| Quebec | A marriage contract must be signed before a notary, and the notary must register a notice of it. Notarial fees are not set by a single province-wide price list. | Quebec marriage contract cost guide |
Independent legal advice and review costs
Each partner should speak with a different lawyer. One lawyer cannot independently advise both people when their rights and interests may differ.
The review price depends on the document and the work required. A limited review of a clear, complete draft may fit a flat-fee package. The cost rises if the reviewing lawyer finds missing disclosure, unclear clauses or terms that need negotiation.
Ask a reviewing lawyer whether the quoted fee includes:
- a meeting to explain the agreement and relevant provincial law
- review of both partners' financial disclosure
- written comments or proposed revisions
- communication with the drafting lawyer
- a certificate or acknowledgement of independent legal advice
- signing and witnessing

Why free or generic templates can cost more later
A free prenup template can be useful as a conversation starter, but it may omit the information and process that make a Canadian agreement easier to review. Common problems include incomplete financial disclosure, language written for another country, missing province-specific signing steps, unclear treatment of the family home, and clauses about support or children that do not reflect Canadian legal limits.
Use the Canadian prenup template checklist to evaluate a draft before relying on it. The lowest-cost sensible route is usually the one that reduces avoidable drafting time without skipping disclosure, appropriate signing formalities, or separate legal advice. See when Canadian prenups may be enforced or set aside for the process issues that matter beyond price.
Online drafting versus lawyer drafting
An online guided draft can be useful when both partners are aligned on the broad plan and want to organize their information before retaining lawyers. It can reduce blank-page drafting and help surface questions about assets, debts, property, business interests and support.
It is not the right endpoint for every couple. Start with custom legal drafting when there is pressure, disagreement, incomplete disclosure, a complex business or trust, cross-border property, major tax consequences, or a significant proposed support waiver.
The practical comparison is not "software or lawyers." It is whether the lawyer begins with an organized working draft or begins the drafting process from the first interview.
How to control prenup legal fees
Agree on goals before drafting
Discuss the broad financial plan before lawyers begin exchanging revisions. Do not negotiate final legal language without advice, but identify the questions you agree on and the ones that remain open.
Prepare complete financial disclosure
Organize recent statements for property, accounts, investments, pensions, debts, businesses and major family loans or gifts. Missing information creates follow-up work and can weaken the agreement.
Ask for a written scope
Confirm whether the fee covers drafting, meetings, disclosure review, revisions, signing, tax and disbursements. A low starting price is not useful if the work you need is outside the package.
Start early
Allow enough time for both partners to choose lawyers, review disclosure and consider revisions without wedding-related pressure. Use the Canadian prenup checklist to organize the timeline and documents. If the conversation itself is the obstacle, start with how to talk about a prenup without fighting.
When lawyer-led drafting is worth the higher cost
Start with a family lawyer before using a guided draft when important terms are disputed, the wedding is close, disclosure is incomplete, or either partner has a corporation, trust, international property, major support issue, or hard-to-value assets.
These guides explain why extra professional work may be justified for entrepreneurs, second marriages and blended families, inheritances and family gifts, significant debt, and crypto assets.
Is a prenup worth the cost?
That depends on the decisions the agreement needs to address. Legal drafting and advice are more likely to justify their cost when a couple is dealing with a home, business, family gifts, inherited wealth, unequal debt, children from an earlier relationship or a planned career sacrifice.
The value is not a guaranteed court result. It is a clearer record of the couple's intentions, disclosure and advice before a dispute exists.

Frequently asked questions
How much does a prenup cost in Canada?
Published flat fees checked in August 2026 ranged from $1,500 to $2,300 plus tax for straightforward drafting by one lawyer. A separate Ontario independent-legal-advice example started at $750 plus tax. The total rises with the second lawyer, negotiation, revisions and complex finances.
Do both partners need separate lawyers?
Each partner should obtain independent advice from a different lawyer. Alberta's Family Property Act has specific separate-lawyer acknowledgement requirements for agreements under sections 37 and 38. Requirements and legal risks differ by province.
Is online prenup drafting cheaper than hiring a lawyer to start from scratch?
It can reduce the document-preparation cost by giving lawyers an organized working draft. The online fee does not include independent legal advice, negotiation or final legal review unless the provider expressly says it does.
Why do prenup quotes vary so much?
Quotes vary because the scope varies. Business interests, trusts, several properties, support terms, incomplete disclosure and negotiation all require more professional time.
Is there a fixed price for a Quebec marriage contract?
No single province-wide fee applies. Quebec requires a marriage contract to be notarized, but the Chambre des notaires du Quebec states that it does not maintain a professional-fee price list.
