A prenup for a second marriage in British Columbia costs $1,500 to $5,000 per spouse in 2026, with total costs ranging from $2,500 to $10,000 for both parties. Under the Family Law Act, S.B.C. 2011, c. 25, s. 92, couples entering remarriage can opt out of British Columbia's default equal division rules to protect assets for children from previous relationships, safeguard inheritances, and establish clear spousal support terms before the wedding.

Why a Prenup Matters More for Second Marriages in British Columbia
A prenup for a second marriage in British Columbia serves a fundamentally different purpose than a first-marriage agreement, protecting accumulated wealth, existing children's inheritances, and retirement assets that have had decades to grow. Under BC Family Law Act s. 84, family property is subject to equal division upon separation, meaning without a prenuptial agreement, your new spouse could claim 50% of assets acquired during the marriage, plus the increase in value of your pre-existing assets.
Statistics Canada reports that approximately 30% of marriages in Canada are remarriages for at least one spouse, with British Columbia having one of the highest remarriage rates in the country. The median age for second marriages in BC is 47 for men and 43 for women, meaning parties typically bring substantial pre-marital assets, pension entitlements, and often children from previous relationships who deserve financial protection.
Blended families face unique challenges that make prenup second marriage British Columbia planning essential. The default property division rules under the Family Law Act do not distinguish between first and second marriages, treating all family property acquired during the relationship as subject to equal division regardless of the source of funds or the existence of children from prior relationships.
What British Columbia Law Says About Marriage Agreements
British Columbia's Family Law Act s. 92 explicitly permits spouses to make written agreements respecting property division that override the default equal division rules. Section 92 allows couples to divide family property or family debt equally or unequally, include or exclude specific items as family property, and value assets differently than standard valuation methods. This statutory authority gives couples entering a prenup second marriage in British Columbia substantial flexibility to customize their financial arrangements.
The Family Law Act s. 93 establishes requirements for enforceable marriage agreements: the agreement must be in writing, signed by both parties, with each signature witnessed by at least one person. While independent legal advice is not legally mandated, BC courts routinely scrutinize agreements where one or both parties lacked legal counsel, making ILA a practical necessity for enforceability.
BC courts apply a "significant unfairness" test under s. 93(3) when reviewing marriage agreements, a notably lower bar than the common law unconscionability standard used in most other Canadian provinces. This means BC courts have broader discretion to set aside agreements that produce unfair outcomes, making proper drafting and full disclosure critical for any prenup second marriage British Columbia couples execute.
Protecting Children from a Previous Marriage
A prenup for a second marriage in British Columbia can designate specific assets as excluded property reserved for children from your previous relationship, ensuring that a future separation does not diminish their expected inheritance. Under Family Law Act s. 85, inheritances, gifts, and pre-relationship assets are already excluded from family property, but the increase in value of these assets during the relationship becomes divisible family property under s. 84(2)(g).
A well-drafted remarriage prenuptial agreement explicitly addresses how excluded property appreciation will be handled, potentially agreeing that all increases in value remain with the original owner rather than becoming shareable family property. This protection is critical for parents who want their RRSP growth, real estate appreciation, or investment returns to ultimately benefit their biological children rather than being split with a subsequent spouse.
The agreement can also coordinate with your estate plan, reinforcing will provisions that direct specific assets to children from your first marriage. Without this coordination, BC's Wills Variation Act allows spouses to challenge wills that inadequately provide for them, potentially overriding your intentions to prioritize your children's inheritance.
Excluded Property vs. Family Property Under BC Law
| Property Type | Default Treatment | Can Prenup Modify? |
|---|---|---|
| Assets brought into relationship | Excluded property (s. 85) | Yes - can clarify and strengthen |
| Increase in value of excluded property | Family property (s. 84(2)(g)) | Yes - can exclude appreciation |
| Inheritances received during marriage | Excluded property (s. 85(1)(b)) | Yes - can protect future inheritances |
| Family home (even if pre-owned) | Family property (s. 84(1)) | Yes - can exclude from equal division |
| Gifts from third parties | Excluded property (s. 85(1)(c)) | Yes - can clarify treatment |
| Pension/RRSP growth during marriage | Family property | Yes - can modify division |
| Business value increase | Family property | Yes - can protect business interests |
| Jointly acquired debts | Family debt, divided equally | Yes - can allocate differently |
Under Family Law Act s. 85, property acquired before the relationship, inheritances, and certain insurance proceeds are excluded from family property division. However, the BC Court of Appeal in Banh v Chrysler (2022 BCCA 74) confirmed that appreciation of excluded property is measured from the date of marriage until the hearing date, not separation, meaning post-separation growth is also shareable.
A prenup second marriage British Columbia agreement can address this appreciation issue by stipulating that all excluded property appreciation remains with the original owner. This provision protects blended family assets from unexpected division claims that could otherwise diminish children's expected inheritances.
Spousal Support Provisions and Their Limits
A prenup for a second marriage in British Columbia can include spousal support waivers or limitations, but these provisions face greater scrutiny than property division terms. Under the federal Divorce Act, R.S.C. 1985, c. 3, s. 15.2, courts retain jurisdiction to order spousal support regardless of prenuptial waivers if one spouse would otherwise suffer undue economic hardship.
BC courts consider several factors when evaluating spousal support waivers: the length of the marriage, the economic consequences of the relationship breakdown, the parties' circumstances at separation versus when signing, and whether the waiver would leave one spouse destitute. A complete spousal support waiver signed before a 20-year second marriage carries less weight than the same waiver in a 3-year relationship.
Practical approaches for prenup second marriage British Columbia spousal support terms include graduated waivers that phase in over time (full support rights after 10 years), lump sum buyout provisions, or caps on duration rather than amount. These structures acknowledge that circumstances change while still providing predictability for estate planning purposes.
Cost Breakdown for a Second Marriage Prenup in BC
| Service | Cost Range | Notes |
|---|---|---|
| Simple prenup (few assets) | $1,500-$2,500 per spouse | Basic property protection |
| Moderate complexity | $2,500-$3,500 per spouse | Business interests, multiple properties |
| High complexity | $3,500-$5,000+ per spouse | Complex trusts, international assets |
| Independent legal advice only | $500-$1,000 per spouse | Reviewing partner's draft agreement |
| Mediation-assisted drafting | $2,000-$4,000 total | Both parties work with mediator |
| Notarization/witnessing | $50-$150 | Required for valid execution |
The prenup cost in British Columbia in 2026 ranges from $1,500 to $5,000 per spouse, with total costs for both parties typically falling between $2,500 and $10,000. Complexity drives costs: second marriages involving business valuations, pension divisions, real estate in multiple jurisdictions, or trust structures require substantially more legal work than straightforward asset protection agreements.
Many BC family lawyers offer fixed-fee packages for prenuptial agreements, which provide cost certainty compared to hourly billing. The investment typically saves far more than it costs: contested property division litigation in BC Supreme Court can easily exceed $50,000-$100,000 per party, making a $5,000 prenup exceptionally cost-effective insurance.
Requirements for an Enforceable Marriage Agreement
British Columbia requires specific formalities for an enforceable prenup second marriage agreement. Under Family Law Act s. 93(1), the agreement must be in writing, signed by both spouses, with each signature witnessed by at least one person who is not a party to the agreement. Verbal prenuptial agreements have no legal effect in British Columbia.
Full and honest financial disclosure is essential for enforceability, even though no specific disclosure format is mandated by statute. Each party should prepare a complete inventory of assets, debts, and income, with supporting documentation where appropriate. Failure to disclose significant assets or debts provides grounds for courts to set aside the agreement under s. 93(3)(a).
Independent legal advice, while not legally required, substantially strengthens enforceability. BC courts in cases like Hartshorne v Hartshorne (2004 SCC 22) have emphasized that where parties lack ILA, agreements face heightened scrutiny. Each party should have their own lawyer review the agreement, explain its implications, and confirm their client understands and voluntarily accepts its terms.
Timing Considerations for Second Marriage Prenups
A prenup for a second marriage in British Columbia should ideally be finalized at least 30-60 days before the wedding to avoid claims of duress or pressure. Agreements presented immediately before the ceremony, when wedding deposits are non-refundable and guests have traveled, face greater risk of being set aside as involuntary.
British Columbia allows couples to execute marriage agreements at any time before or during the marriage. Agreements signed after the wedding are called postnuptial agreements but receive identical treatment under Family Law Act s. 92. Couples who marry without a prenup can still protect assets through a postnuptial agreement, though courts may scrutinize the circumstances of later execution.
For blended families, the best practice is to begin prenup discussions as soon as engagement occurs, allowing adequate time for financial disclosure, lawyer consultations, negotiations, and revisions without time pressure that could undermine enforceability.
What Cannot Be Included in a BC Prenup
British Columbia law prohibits certain provisions in prenuptial agreements, regardless of what the parties agree. Under Family Law Act s. 44, agreements about parenting arrangements (decision-making responsibility and parenting time) made before separation are not binding. Courts will always determine parenting matters based on children's best interests at the time of separation, not pre-arranged terms.
Similarly, Family Law Act s. 148 limits enforceable child support agreements to those made after separation or in contemplation of imminent separation. Parents cannot waive, limit, or pre-determine child support obligations in a prenuptial agreement, as these rights belong to children rather than parents.
Provisions attempting to impose penalties for marital misconduct, dictate lifestyle choices, or create illegal arrangements will not be enforced by BC courts. A prenup second marriage British Columbia agreement should focus on property division and spousal support rather than attempting to regulate personal behavior during the marriage.
Modifying or Cancelling a Marriage Agreement
British Columbia couples can amend or cancel their prenuptial agreement at any time by mutual written agreement. Under the Family Law Act, any modification must follow the same formalities as the original agreement: in writing, signed by both parties, with witnessed signatures. Oral modifications are not enforceable.
Common triggers for prenup amendments in second marriages include birth or adoption of children together, significant changes in asset values, one spouse's retirement, inheritance of substantial assets, or changes in one party's health or earning capacity. Regular review every 5-7 years helps ensure the agreement remains fair and reflects current circumstances.
Either party can apply to court to set aside or replace a marriage agreement provision under Family Law Act s. 93(5). Courts consider factors including the length of time since execution, whether the agreement considered relevant circumstances, and whether circumstances have changed significantly. Agreements that produced fair results when signed may become unenforceable if dramatically changed circumstances make them significantly unfair at separation.
Estate Planning Integration for Blended Families
A prenup for a second marriage in British Columbia should coordinate with comprehensive estate planning to protect children from previous relationships. BC's Wills Variation Act permits spouses and children to challenge wills that inadequately provide for them, potentially overriding testamentary intentions despite a valid prenup.
Effective blended family estate planning combines prenuptial agreements with updated wills, trust arrangements, life insurance designations, and RRSP/TFSA beneficiary designations. The prenup can include acknowledgment clauses where each spouse waives wills variation claims against the other's estate, reinforcing estate planning objectives.
Consider establishing trusts for children from previous relationships, funded by life insurance or designated assets. These structures remove assets from potential spousal claims while ensuring children receive their intended inheritance regardless of how the second marriage ends.
Working with a BC Family Law Lawyer
Locating qualified legal counsel for a prenup second marriage in British Columbia involves several steps. The Law Society of British Columbia's lawyer directory at lawsociety.bc.ca allows searches by practice area and location. Family law specialists certified by the Law Society have demonstrated expertise through additional qualifications and practice experience.
During initial consultations (typically $150-$300 or sometimes free), discuss the lawyer's experience with second marriage prenups specifically, their approach to disclosure requirements, typical timeline and costs, and how they handle negotiations with the other party's counsel. Look for lawyers who understand both family law and estate planning implications for blended families.
Many BC communities have limited family law resources, particularly outside the Lower Mainland. Virtual consultations have become widely accepted, allowing couples in smaller communities to access experienced Vancouver-area family lawyers without geographic constraints.

How much does a prenup cost for a second marriage in BC?
A prenup for a second marriage in British Columbia costs $1,500 to $5,000 per spouse in 2026, with total costs typically ranging from $2,500 to $10,000 for both parties.

Can a BC prenup protect my children from a previous marriage?
Yes, a prenup second marriage British Columbia agreement can designate specific assets as excluded property reserved for your children from a previous relationship. The agreement can also waive your spouse's potential wills variation claims and coordinate with your estate plan to ensure children receive their intended inheritance upon your death or divorce.
What happens to property appreciation under a BC prenup?
Under Family Law Act s. 84(2)(g), the increase in value of excluded property during the relationship becomes family property subject to equal division. However, a properly drafted prenup can stipulate that all appreciation remains with the original owner, protecting growth in pre-marital assets, inheritances, and investments from division.
Can I include spousal support waivers in my second marriage prenup?
Yes, BC marriage agreements can include spousal support waivers or limitations, but courts retain discretion to override these provisions if enforcement would cause significant unfairness. Under the federal Divorce Act s. 15.2, courts may order support regardless of waivers if one spouse would suffer undue economic hardship.
Do both parties need lawyers for a BC prenup?
While not legally required, independent legal advice for both parties is strongly recommended and substantially strengthens enforceability. BC courts scrutinize agreements where one or both parties lacked legal counsel, particularly where power imbalances exist. Each lawyer costs approximately $500-$1,000 for ILA review only, or $1,500-$5,000 for full drafting services.
How far before the wedding should we sign our prenup?
A prenup for a second marriage should be finalized at least 30-60 days before the wedding to avoid claims of duress or coercion. Starting negotiations 3-6 months before the ceremony allows adequate time for financial disclosure, lawyer consultations, and thoughtful negotiation without wedding-day pressure that could undermine enforceability.
Can we change our prenup after we're married?
Yes, British Columbia couples can amend or cancel their prenuptial agreement at any time through a new written agreement signed by both parties with witnessed signatures. Regular review every 5-7 years is recommended to ensure the agreement reflects current circumstances, particularly after significant life changes like retirement or inheritance.
What cannot be included in a BC marriage agreement?
British Columbia prohibits certain prenup provisions. Under Family Law Act s. 44, pre-separation parenting arrangement terms are not binding. Under s. 148, child support agreements are only enforceable if made after separation. Provisions imposing penalties for infidelity or attempting to dictate personal behavior will not be enforced.
Will a BC court automatically enforce our prenup?
Not automatically. BC courts under Family Law Act s. 93 can set aside agreements that are significantly unfair. Courts consider whether there was full financial disclosure, whether both parties had independent legal advice, whether circumstances have changed dramatically, and whether enforcement would produce an unconscionable result. Proper drafting and execution substantially increase enforcement probability.
