Key Takeaways
- 1.BC's Family Law Act treats common-law partners of 2+ years identically to married spouses for property division — no agreement needed for rights to apply.
- 2.The jointly titled $650K home is family property: each partner is entitled to $325,000 (half the equity after any mortgage), minus excluded pre-relationship contributions.
- 3.The $180K RRSP growth during the relationship is family property — the non-holder is entitled to half the relationship-period growth, even though the account is in one name only.
- 4.A direct RRSP-to-RRSP spousal rollover on separation is tax-free. Withdrawing the same amount to pay cash triggers up to $33,000+ in combined tax at the top BC marginal rate.
- 5.All property is valued as of the date of separation — not the date of sale, transfer, or agreement. Documenting this date in writing is critical.
The Scenario: 5-Year BC Common-Law Relationship, No Agreement
Our model case involves two partners who moved in together in Vancouver in 2021 and are separating in 2026 after five years of cohabitation. They never signed a cohabitation agreement. Their combined assets are:
- Home: Jointly titled (50/50) condo in Vancouver, current fair market value $650,000, remaining mortgage $200,000, net equity $450,000.
- RRSP: $180,000 in Partner A's name only. Partner A had $30,000 in the RRSP before the relationship began. The remaining $150,000 accumulated during the five-year relationship through contributions and investment growth.
- Other assets: Minimal — each partner has personal savings under $10,000 and no significant debts beyond the mortgage.
Because they lived together in a marriage-like relationship for more than two years, BC's Family Law Act (FLA) classifies them as spouses. The FLA property division rules apply automatically. For context on how BC handles property transfers and taxes, see our BC Property Transfer Tax Calculator.
BC Family Law Act: Why Common-Law Equals Married
This is the single most important thing to understand: since March 18, 2013, when the FLA came into force, BC has treated common-law partners (called "spouses" in the Act) the same as married couples for property division purposes. The threshold is simply living together in a marriage-like relationship for at least two continuous years.
The FLA creates two categories of property:
- Family property: Everything either spouse owns at the date of separation, including the family home, bank accounts, investments, RRSPs, pensions, and business interests. Family property is presumed to be divided equally (50/50).
- Excluded property: Assets one spouse brought into the relationship, inheritances received during the relationship, and gifts from third parties. Excluded property stays with the original owner — but any increase in value of excluded property during the relationship is itself family property.
Without a cohabitation agreement, there is no mechanism to override these defaults except a court order based on "significant unfairness." That is a high bar. For most couples, the 50/50 default applies in full.
Dividing the $650K Home: Equity Split Calculation
The home is jointly titled, so both partners already have legal ownership. Under the FLA, the net equity is family property regardless of who made mortgage payments or contributed to the down payment (unless one partner can trace a pre-relationship contribution as excluded property).
| Home Division | Amount |
|---|---|
| Fair market value (date of separation) | $650,000 |
| Outstanding mortgage | ($200,000) |
| Net equity | $450,000 |
| Each partner's share (50/50) | $225,000 |
If one partner contributed the entire $100,000 down payment from pre-relationship savings, that $100,000 would be excluded property. The remaining $350,000 in equity would be split $175,000 each, and the contributing partner would receive $275,000 total ($100,000 excluded + $175,000 family property).
In practice, the couple has three options for the home: sell it and split the proceeds, have one partner buy out the other's share, or continue co-owning (rare). If one partner buys out the other, they need to refinance the mortgage in their name alone and pay the other partner $225,000. The buy-out transfer between separating spouses is exempt from BC's Property Transfer Tax under section 14(4)(a) of the Property Transfer Tax Act — saving up to $11,000 on a $650,000 property.
Dividing the $180K RRSP: The Excluded Property Trap
Partner A holds $180,000 in RRSPs. The FLA requires separating the pre-relationship value (excluded property) from the growth during the relationship (family property):
| RRSP Division | Amount |
|---|---|
| Total RRSP value (date of separation) | $180,000 |
| Pre-relationship value (excluded property) | ($30,000) |
| Family property portion (growth during relationship) | $150,000 |
| Partner B's entitlement (50% of family property) | $75,000 |
| Partner A retains | $105,000 |
Partner A keeps $30,000 (excluded) + $75,000 (their half of family property) = $105,000. Partner B receives $75,000. The key nuance: investment growth on the original $30,000 during the relationship is also family property under section 84(2)(g) of the FLA — this is not intuitive and is frequently missed.
Proof burden: Partner A must prove the $30,000 pre-relationship value with documentation — RRSP statements from the date cohabitation began. Without proof, the entire $180,000 is treated as family property and split 50/50 ($90,000 each). Keep your statements.
RRSP Spousal Rollover vs Withdrawal: The $33,000 Tax Difference
Partner A owes Partner B $75,000 from the RRSP division. There are two ways to pay this: transfer RRSP-to-RRSP (spousal rollover) or withdraw and pay cash. The tax consequences are dramatically different.
| Method | Amount Transferred | Immediate Tax | Net to Partner B |
|---|---|---|---|
| Direct RRSP-to-RRSP rollover | $75,000 | $0 | $75,000 (in RRSP) |
| Withdraw and pay cash | $75,000 withdrawal | ~$33,375 (44.5% marginal) | ~$41,625 (cash) |
The 44.5% rate assumes Partner A is in the $106K–$155K combined federal/BC bracket (29% federal + 15.5% BC provincial). Additionally, the RRSP withholding tax on amounts over $15,000 is 30% at source, with the balance owing at tax filing time.
The spousal rollover under subsection 146(16) of the Income Tax Act requires a written separation agreement or court order. The funds move directly between registered accounts — Partner A's RRSP to Partner B's RRSP — with no tax event. Partner B pays tax only when they eventually withdraw the funds in retirement, ideally at a lower marginal rate. For strategies on managing RRSP withdrawals efficiently, see our RRSP Meltdown Strategy Calculator.
If Partner A does not have sufficient RRSP room or wants to keep their RRSP intact, they can pay the $75,000 equalization from other assets (for example, by adjusting the home equity split). This is often the better approach when the RRSP holder wants to preserve their retirement savings and has enough home equity to offset the difference. Our spousal RRSP calculator covers the contribution strategies that could have reduced this exposure during the relationship.
The Date of Separation: Why It Sets Everything
Under BC's FLA, all family property is valued as of the date of separation. This single date determines:
- Property values: The home's $650,000 FMV and the RRSP's $180,000 balance are frozen at this date for division purposes.
- Debt balances: The $200,000 mortgage balance on the separation date is the number used, even if payments continue.
- Excluded property calculations: Growth on excluded property is measured from the start of cohabitation to the separation date.
- Limitation period: Each spouse has two years from the date of separation to make a property division claim under the FLA. Miss this deadline and you lose the right to claim.
The date of separation is when one or both partners communicate the intention to end the relationship permanently. It is not necessarily when someone moves out — couples can be "separated under one roof" if they have clearly communicated the end of the relationship. Document the date in writing (email, text message, or letter) to avoid disputes later.
Timing risk: If the home appreciates from $650,000 to $700,000 between separation and sale, the $50,000 gain is not automatically split 50/50 under the FLA framework. Post-separation changes in value are handled differently — typically proportional to ownership interest or as negotiated. Delaying the formal separation date to capture a rising market (or accelerating it to avoid a falling one) is a real strategic consideration, but courts can look through artificial manipulation.
BC Homeowner Grant: Repayment Risk on Sale
Both partners have been claiming the BC homeowner grant on the property — up to $570 per year for the basic grant ($770 for seniors, veterans, or people with disabilities). When the property is sold or transferred on separation, the grant itself does not need to be repaid as long as the property was genuinely owner-occupied as a principal residence during the grant years.
The repayment risk arises in two scenarios:
- One partner moves out before sale: If Partner B moves out and the home is not sold for 12+ months, the property may lose principal-residence status for Partner B. If Partner B claimed the grant on a different property during that period, there could be a clawback on the original home's grant.
- Rental conversion: If neither partner lives in the home after separation and it is rented out, grants claimed during the rental period would need to be repaid. At $570 per year, two years of incorrectly claimed grants is $1,140 — not catastrophic but avoidable.
The more significant tax concern on sale is the principal residence exemption (PRE). As long as the home was the principal residence of at least one spouse for every year it was owned, the capital gain on sale is fully exempt. If you are navigating PRE calculations for multiple properties, our Principal Residence Exemption Calculator walks through the formula for BC properties.
Full Asset Division Summary
Here is the complete picture of what each partner walks away with under the FLA defaults, assuming no excluded property claims on the home and a $30,000 excluded RRSP amount for Partner A:
| Asset | Partner A | Partner B |
|---|---|---|
| Home equity ($450,000 net) | $225,000 | $225,000 |
| RRSP — excluded (pre-relationship) | $30,000 | $0 |
| RRSP — family property ($150,000) | $75,000 | $75,000 |
| Total | $330,000 | $300,000 |
The $30,000 difference reflects Partner A's excluded RRSP property. If Partner A cannot prove the pre-relationship value, the split becomes $315,000 each. Note that RRSP values are pre-tax — Partner A's $105,000 RRSP is worth approximately $58,000–$73,000 after tax depending on their withdrawal rate and marginal bracket.
What a Cohabitation Agreement Would Have Changed
A cohabitation agreement signed before or during the relationship could have altered the FLA defaults in several important ways:
- Preserved pre-relationship equity. If Partner A contributed $80,000 of the down payment from savings, an agreement could have specified that amount as excluded from division — reducing Partner B's home equity share by $40,000.
- Protected the RRSP entirely. The agreement could have specified that each partner's registered accounts remain their own property. Partner B would receive $0 from the RRSP instead of $75,000.
- Set an alternative division ratio. Instead of 50/50, the agreement could have specified any split the parties agreed to — for example, 60/40 in favour of the higher earner or based on proportional contributions.
- Specified a valuation mechanism. Rather than relying on the date-of-separation FMV, the agreement could have set a formula (for example, average of two independent appraisals) to reduce disputes.
The cost of a cohabitation agreement in BC is typically $2,500–$5,000 for both parties (each needs independent legal advice for the agreement to be enforceable). Compared to the $75,000 RRSP division in this scenario, the agreement would have been an extremely cost-effective investment.

Practical Steps After Separation
- Document the separation date. Send a written communication (email or text) clearly stating the relationship is over. This starts the two-year limitation clock and sets the valuation date.
- Gather financial records. Collect RRSP statements from the date cohabitation began, the current mortgage statement, a recent property assessment or appraisal, and any evidence of pre-relationship asset values.
- Get independent legal advice. Each partner should consult their own family lawyer. BC offers free initial consultations through the Lawyer Referral Service ($25 for 30 minutes). Do not share a lawyer.
- Draft a separation agreement. Once both parties agree on the division, formalize it in a written separation agreement. This document is required for the RRSP spousal rollover and protects both parties from future claims.
- Execute the RRSP transfer before withdrawing. If dividing the RRSP, instruct the financial institution to process a direct RRSP-to-RRSP transfer under subsection 146(16). Do not withdraw and re-contribute — this uses contribution room and triggers withholding tax.
- File within two years. If you cannot reach an agreement, file a Notice of Family Claim in BC Supreme Court before the two-year limitation expires. After two years, your right to claim property division is lost.
Important Disclaimer
This article provides general information based on BC's Family Law Act (SBC 2011, c. 25), the Income Tax Act of Canada (subsection 146(16) regarding RRSP transfers on relationship breakdown), and BC's Property Transfer Tax Act (section 14(4)(a) spousal exemption). The scenario uses simplified assumptions — a jointly titled home, one RRSP with a clear pre-relationship balance, no children, and no significant debts beyond the mortgage. Real separations involve additional complexity including pension division, business valuation, spousal support calculations, and child-related considerations. Property division laws vary significantly by province. This is not legal, tax, or financial advice. Always consult a qualified BC family lawyer and a tax professional before making decisions about property division on separation.
