BC Marriage Agreements: Your Guide to Prenups in British Columbia

Everything BC couples need to know about marriage agreements (prenups), from the Family Law Act and property division to enforceability tips and legal requirements.

February 4, 20256 min readprenups.ai

British Columbia is home to some of Canada's most breathtaking wedding backdrops--from the mountains of Whistler and the gardens of Victoria to the urban sophistication of Vancouver. But beyond the ceremony planning, engaged couples across BC are increasingly turning their attention to an important legal conversation: the marriage agreement.

In British Columbia, what most people call a prenup is formally known as a "marriage agreement." Whether you are a tech professional in Vancouver, a business owner in Kelowna, or a young couple starting out in Kamloops, understanding how marriage agreements work under BC's Family Law Act is an essential step in preparing for married life.

What Is a Marriage Agreement in BC?

A marriage agreement is a written contract between two people who plan to marry or who are already married. It sets out how property, debt, and spousal support will be handled during the relationship and in the event of separation. Under BC's Family Law Act, marriage agreements fall under the broader category of "agreements" that spouses or prospective spouses can enter into.

Marriage agreements give couples the ability to create their own financial framework rather than relying entirely on the default rules of the Family Law Act.

How Property Division Works in British Columbia

BC's Family Law Act divides property into two categories:

Family Property

Family property includes most assets acquired by either spouse during the relationship, including the family home, savings, investments, pensions, and the growth in value of excluded property. Family property is generally divided equally upon separation.

Excluded Property

Excluded property includes assets that one spouse owned before the relationship began, as well as gifts and inheritances received during the relationship. While excluded property itself may be protected, any increase in its value during the relationship is considered family property and is subject to equal division.

Without a marriage agreement, these default rules apply. A marriage agreement lets couples modify how property is categorized and divided, giving them more control over the outcome.

Legal Requirements for a Valid Marriage Agreement

For a marriage agreement to hold up in BC, the following conditions should be met:

  • Written and signed: The agreement must be in writing and signed by both parties.
  • Voluntary consent: Both parties must enter the agreement freely, without coercion or pressure.
  • Full financial disclosure: Each party must provide complete and honest information about their finances, including assets, debts, and income.
  • Independent legal advice: While not a strict statutory requirement, independent legal advice for each party is strongly recommended. Courts view agreements far more favourably when both parties had the benefit of their own lawyer.
  • Witnesses: Having witnesses to the signing is recommended and can strengthen the agreement's enforceability.
  • Notarization: Not required but recommended as an additional layer of protection.

The "Significantly Unfair" Standard

One important feature of BC law is that courts can set aside a marriage agreement if it is "significantly unfair." This is a lower threshold than the unconscionability standard used in some other provinces, meaning BC courts have somewhat more latitude to intervene if the terms of an agreement produce an unjust result. Factors courts consider include the length of the relationship, whether the agreement was made in good faith, and whether circumstances have changed substantially since the agreement was signed.

What Can Be Included in a BC Marriage Agreement

A comprehensive marriage agreement in British Columbia can address:

  • Property division: Specify how family property and excluded property will be treated upon separation, including real estate, investments, and personal property.
  • Debt allocation: Clarify responsibility for debts brought into the marriage or incurred during it, such as student loans, mortgages, or business debts.
  • Spousal support: Set out terms for spousal support, though courts retain broad discretion under both the Family Law Act and the federal Divorce Act to award spousal support regardless of what the agreement says.
  • Business interests: Protect a business or professional practice from division, an especially relevant consideration for entrepreneurs in BC's thriving startup and resource sectors.
  • Pensions and retirement: Address how pensions, RRSPs, and other retirement savings will be handled, including CPP credit splitting.
  • Inheritance and gifts: Define how inheritances and gifts will be treated, particularly important for families passing down property or wealth.

Why BC Couples Are Choosing Marriage Agreements

Real Estate Values

With property prices in Vancouver and the Lower Mainland among the highest in Canada, couples who own property before marriage have strong incentives to clarify how that equity will be treated. A marriage agreement can protect a down payment funded by family or pre-relationship savings.

Entrepreneurship and Business Protection

From tech companies on the North Shore to wineries in the Okanagan and forestry businesses in Prince George, BC has a vibrant entrepreneurial culture. A marriage agreement can shield a business from the uncertainty of property division.

Blended Families and Second Marriages

Couples in communities like Surrey, Burnaby, and Nanaimo who are remarrying or who have children from prior relationships often use marriage agreements to protect assets earmarked for those children while still being fair to their new partner.

International Assets

Vancouver's diverse population means many couples have assets or family connections in other countries. A marriage agreement can provide clarity on how international assets are addressed under BC law.

Tips for Creating a Marriage Agreement in BC

  • Start early: Raise the topic well before the wedding. An agreement signed at the last minute may face scrutiny over whether it was truly voluntary.
  • Disclose everything: Incomplete financial disclosure is one of the primary reasons agreements are set aside. Be thorough and honest.
  • Hire separate lawyers: Each party should have their own independent legal counsel. This is the strongest safeguard for enforceability.
  • Keep it fair: Given BC's "significantly unfair" standard, agreements that are one-sided or that leave one spouse in a difficult financial position are vulnerable to being overturned. Build fairness into the agreement from the start.
  • Include a review mechanism: Consider adding a sunset clause or a provision for periodic review. Relationships evolve, and an agreement that was fair at the outset may become less so over time.
  • Plan for life changes: Anticipate major events like having children, career changes, or relocation, and include provisions for how the agreement may be updated.

Final Thoughts

A marriage agreement is a practical and increasingly common step for BC couples preparing for married life. Whether you are exchanging vows in a Vancouver rooftop venue, a vineyard in Penticton, or a lodge in Tofino, taking the time to discuss your financial future openly and formalize your understanding in a properly drafted marriage agreement is a meaningful investment in your partnership. With the right approach, it is a process that can bring you closer together rather than driving you apart.
