Prenuptial Agreement in
British Columbia
In British Columbia, prenuptial agreements are formally known as "marriage agreements" and are governed by the Family Law Act, which was significantly updated in 2013. BC family property law divides property acquired during the relationship equally, while excluded property — such as assets brought into the relationship or received as gifts or inheritances — may be protected. Notably, BC courts can set aside a marriage agreement if it is "significantly unfair," a lower threshold than the unconscionability standard used in many other provinces, making careful drafting and independent legal advice especially important.
Property division
How British Columbia handles marital property
British Columbia divides property under the Family Law Act. Family property (acquired during the relationship) is generally divided equally, while excluded property (pre-relationship assets, gifts, inheritances) may be protected.
Legal framework
Provincial family law in British Columbia
Prenuptial agreements in BC (called "marriage agreements") are governed by the Family Law Act. The agreement must be in writing and signed by both parties. Courts may set aside an agreement if it is significantly unfair.
Independent legal advice for both parties is strongly recommended in BC. The Family Law Act allows courts to set aside agreements that are "significantly unfair," which is a lower threshold than unconscionability.

Best practices
Tips for a strong prenup in British Columbia
Following these best practices helps ensure your agreement is clear, fair, and enforceable.
Ensure both parties each retain their own BC family lawyer — the Family Law Act's "significantly unfair" standard means courts look closely at whether both spouses truly understood and agreed to the terms.
Provide thorough financial disclosure of all assets, debts, income, and liabilities; BC courts consider inadequate disclosure a strong indicator that an agreement should be set aside.
Begin the drafting process well before the wedding — last-minute signing is a red flag for courts assessing whether the agreement was entered into voluntarily.
Clearly distinguish between excluded property and family property in the agreement, specifying whether and how growth in value of excluded assets will be shared.
Consider including a review mechanism or sunset clause, as BC's significant unfairness standard means an agreement that becomes grossly imbalanced over time is more vulnerable to challenge.
FAQ
Common questions about prenups in British Columbia
What is a prenuptial agreement called in British Columbia?
In BC, the agreement is called a "marriage agreement" under the Family Law Act. The term "domestic agreement" is also sometimes used. The agreement must be in writing and signed by both parties. Unlike a cohabitation agreement (which applies to unmarried couples), a marriage agreement specifically addresses the rights and obligations of spouses.
What does "significantly unfair" mean for BC marriage agreements?
Under the BC Family Law Act, a court can set aside or replace a provision of a marriage agreement if following it would be "significantly unfair." This is a notably lower bar than the unconscionability test used in most other provinces. Courts consider factors like how long ago the agreement was made, whether it took into account the interests of children, and whether the circumstances of the parties have changed significantly since signing.
Does a BC marriage agreement need to be witnessed or notarized?
Notarization is not a statutory requirement in BC, but having both parties sign in front of independent witnesses — and ideally before a notary public — is strongly recommended. It creates a clear evidentiary record of voluntary execution and can significantly help if the agreement is challenged.
Can a BC prenuptial agreement protect an inheritance I receive after we marry?
Yes. Under the BC Family Law Act, gifts and inheritances received by one spouse during the relationship are classified as excluded property and are not subject to equal division. A well-drafted marriage agreement can confirm this exclusion and also clarify what happens if inherited funds are used toward shared property such as the family home.
Does a BC marriage agreement apply to common-law couples?
The BC Family Law Act extends many of the same property division rights to spouses who have lived together in a marriage-like relationship for at least two years. If you are not yet married but want to address property rights before cohabiting, the appropriate document is a cohabitation agreement rather than a marriage agreement. Both types of agreement fall under the same legislative framework.
