The client
A separating spouse in Salmon Arm had received a $55,000 inheritance mid-relationship, deposited it into the couple's joint account, and used it -- mixed in with joint savings -- toward the down payment on their $590,000 jointly-titled home.

The problem
British Columbia's Family Law Act excludes an inheritance from family property, whichever spouse received it and whenever it arrived. That protection depends entirely on being able to trace the money -- once it is deposited into a joint account and spent alongside ordinary household funds, the exclusion has nothing left to attach to.
Why the deposit, not the inheritance itself, was the problem
- ▸The inheritance was never disputed as an inheritance -- both spouses agreed where the $55,000 came from
- ▸It went into a joint account that also held employment income, RRSP withdrawals and ordinary savings, with no record of what paid for what
- ▸Once commingled beyond tracing, ss.84-85 of British Columbia's Family Law Act treat the whole amount as family property, not merely its growth since the relationship began
A cleanly-kept inheritance in BC is excluded, base value and all. A commingled one simply becomes family property -- there is no partial credit for having once been separate.
The numbers
Once tracing failed, sizing the buyout to the full equity -- not the smaller, traceable-exclusion figure -- was straightforward arithmetic.
| Pricing the buyout once the exclusion was lost | Amount |
|---|---|
| Home equity | $260,000 |
| Buyout paid (50% of the full, undivided equity) | $130,000 |
| What a traced exclusion would have cost instead (50% of $205,000) | $102,500 |
| Total debt service, keeping spouse's own income | Figure |
|---|---|
| Payment at the qualifying rate (6.80%), 25 years | $3,165/mo |
| Property tax | $410/mo |
| Heat (lender estimate) | $150/mo |
| Car loan | $320/mo |
| Total debt service | 39.7% |
39.7% still cleared on the keeping spouse's own income, but the $27,500 the lost exclusion cost is exactly the gap between what a traceable inheritance protects and what a commingled one no longer can, a distinction home-price data alone never shows.
The solution
A submortgage broker licensed under BC's Mortgage Brokers Act treated the tracing question as the family lawyer's to answer definitively before the refinance was sized, rather than assuming the inheritance would simply be credited back.
First, had the family lawyer review the bank records from the year the inheritance was received, confirming there was no way to isolate the $55,000 from the account's other funds at the time of the down payment.
Second, confirmed in writing that BC's tracing rule, not a full-exclusion assumption, governed the outcome -- the client had heard how inheritances work generally and expected it to still apply.
Third, sized the refinance to the full $130,000 buyout once it was clear no partial exclusion could be recovered, qualifying the keeping spouse on their own income alone.
The outcome
The refinance funded at 4.80%, the departing spouse received the full $130,000 buyout, and total debt service settled at 39.7%.
Because this is an uninsured refinance, CMHC's ratio maximums do not apply directly; the 39.7% figure is informational.
What to take from this file
- 01Excluded property in BC has to stay traceable to stay excluded. Depositing it into a joint account and spending it alongside other funds can erase the exclusion entirely, not just its growth.
- 02Losing an exclusion this way costs the whole base value, not merely the increase. That is a materially larger number than a lost-growth-only outcome.
- 03Advise clients early to keep an inheritance or gift in its own account. By the time a mortgage file is open, the commingling has usually already happened.
- 04Confirm tracing succeeded or failed with the family lawyer before sizing a buyout. Assuming an inheritance is automatically protected can misprice the file by tens of thousands of dollars.
