Not the family home, and not a 50/50 split either

an Alma buyout under Quebec's acquêts regime

The property being divided was a cottage bought during the marriage, not the family home -- so Quebec's family patrimony rules never applied. Under société d'acquêts, one spouse's traceable inheritance stayed entirely theirs, and only the remaining acquêts equity split 50/50.

The client

An ex-spouse in Alma is buying out the other's share of a $310,000 cottage bought during the marriage, carrying a $185,000 mortgage. Neither spouse ever treated this property as their family home -- that was a separate house, already dealt with.

The problem

Because this cottage was never the family home, Quebec's family patrimony rules -- which mandate an even split of specific family-use property regardless of who paid for what -- never applied to it at all. It falls instead under société d'acquêts, the province's default matrimonial regime: property acquired during the marriage (the acquêts) splits 50/50, but a spouse's traceable inheritance (their propre) stays theirs alone and never enters the split.

Why a flat 50/50 split would have overpaid

  • $22,000 of the original purchase money was traced directly to one spouse's inheritance, received during the marriage but never commingled beyond this specific contribution
  • A propre stays with the spouse who owns it; it is never part of the acquêts pool that gets divided
  • Splitting the full $125,000 in equity 50/50 -- ignoring the propre -- would have paid the other spouse $11,000 that was never part of the acquêts to begin with

Priced on a flat 50/50 assumption, the buyout would have been $62,500. Priced on société d'acquêts's actual propre/acquêts split, it was $51,500 -- a real, quantifiable difference, not a rounding matter.

The numbers

The refinance math itself was routine once the propre was correctly excluded, a figure that sits alongside the broader Canadian home-price history this specific equity was measured against.

The buyout, propre excluded before the splitAmount
Total equity ($310,000 value less $185,000 balance)$125,000
Less: one spouse's traceable inheritance (propre, excluded)-$22,000
Acquêts equity remaining, to split 50/50$103,000
Correct buyout (50% of the acquêts only)$51,500
New mortgage (existing balance + correct buyout)$236,500
TDS at the qualifying rateFigure
Minimum qualifying rate on a 4.90% contract rate6.90%
Payment at the qualifying rate, 22 years remaining$1,730
Property tax and heat$395
TDS (payment + tax + heat + car loan) ÷ $7,500 income31.9%

This file is uninsured, so there's no CMHC ratio ceiling; 31.9% TDS is informational, confirming the refinance was never a ratio problem -- only a matrimonial-regime math problem.

The solution

A courtier hypothécaire (mortgage broker) licensed under Quebec’s Act respecting the distribution of financial products and services treated the property's own history, not its current value alone, as the starting point.

First, confirmed with the notary that the cottage was never the family home, establishing that family patrimony's mandatory-split rules didn't apply here at all -- société d'acquêts did.

Second, had the notary trace the $22,000 inheritance's path directly into the original purchase, confirming it as a propre excluded from the acquêts before any split was calculated.

Third, structured the buyout refinance to fund only the correct $51,500 acquêts buyout, not the $62,500 a naive 50/50 split of the full equity would have produced.

Confirmation from the notary that the property is not, and was never treated as, the family home
Documentary trail tracing the $22,000 inheritance into the original purchase
Notarial calculation separating the propre from the acquêts before any buyout figure was set
New mortgage commitment confirming the $236,500 refinance amount
Notarial deed confirming the correct, propre-adjusted buyout amount actually paid
№ 05

The outcome

The refinance closed at $236,500, TDS 31.9%, with the $22,000 inheritance excluded exactly as société d'acquêts requires and only the true $51,500 acquêts half actually bought out.

This file assumes an even split of the acquêts once the propre is excluded; actual entitlement depends on the specific matrimonial regime and any marriage contract, and is not always 50/50.

What to take from this file

  • 01Not every property in a divorce falls under family patrimony. A cottage or rental bought during the marriage, if it isn't the family home, falls under société d'acquêts instead -- a genuinely different regime.
  • 02A traceable inheritance is a propre, and a propre never enters the 50/50 acquêts split. Confirm the money's path before assuming the full equity divides evenly.
  • 03A flat 50/50 split of total equity can overpay the other spouse by exactly the amount of an excluded propre. In this file, that was $11,000.
  • 04Ask early which matrimonial regime actually applies to the specific property. The family residence and every other asset can be governed by two different sets of rules in the same divorce.
  • 05Have the notary do the propre/acquêts tracing before quoting any buyout number. A number quoted first and corrected later is harder to walk back than one built correctly from the start.

Illustrative in this file — lender-specific, not rules:

  • 4.90% rate — rates move daily; not a quote.
  • the TDS figure — this file is uninsured, so there is no CMHC ratio ceiling -- the number is informational, not a pass/fail line.
  • the 50% acquêts split — this file assumes an even split of the acquêts once the propre is excluded; actual entitlement depends on the specific matrimonial regime and any marriage contract, and is not always 50/50.
