The agreement that outlived the marriage

a Cowansville cottage's convention d'indivision kept binding through the divorce

A Quebec couple's family patrimony equalization covered their family residence -- but a rental cottage bought together years earlier, held outside family patrimony, was bound by its own registered convention d'indivision. That agreement's fixed term did not end just because the marriage did.

Anonymized illustration. The borrowers, dollar figures, and rates in this file are an illustrative composite — no real client is identifiable, and any rate shown is illustrative, not a quote. The rules are real: every regulatory figure is cited to its source in the Sources section, and the math computes exactly as shown.

The client

The problem

Quebec's mandatory family patrimony covers the family residence -- it says nothing about a second property, like a rental cottage, that a couple happens to co-own together outside it. That cottage is governed by ordinary civil-code co-ownership rules instead, and this couple had signed a convention d'indivision at purchase.

What the agreement actually said

  • The convention d'indivision (arts. 1012-1013 C.c.Q.) fixed a term during which neither co-owner could unilaterally demand a partition or force a sale
  • Six years of that term remained at the time of the divorce
  • Nothing about a divorce cancels a separate contract the same two people signed as co-owners, not as spouses

The couple assumed the divorce settled everything about the cottage too. The agreement they'd signed years earlier had other ideas.

The numbers

Once the notary confirmed the agreement was still in force, pricing the mutual buyout was straightforward.

Buying out the departing spouse's registered shareAmount
Cottage equity$160,000
Departing spouse's registered 50% share$80,000
New consolidated balance$230,000
Total debt serviceFigure
Payment at the qualifying rate (6.95%), 20 years$1,763/mo
Property tax + heat$390/mo
Total debt service, keeping spouse alone38.6%

38.6% sits comfortably in range for an uninsured refinance -- home-price levels not far off what Canadian home price history shows for a second property of this kind. The real work in this file was confirming what the agreement actually allowed, not the arithmetic.

The solution

A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services treated the cottage as its own, separate co-ownership question -- not an extension of the family patrimony settlement already underway.

First, confirmed with a notary that the convention d'indivision's term had not yet expired. Six years remained, during which neither co-owner could force a sale unilaterally.

Second, confirmed that only a MUTUAL buyout -- not a court application -- could resolve the cottage while the agreement ran. Both spouses, fortunately, were willing.

Third, structured the keeping spouse's solo refinance around the registered 50% share, funding the departing spouse's $80,000 buyout as part of one consolidated balance.

Confirmation that both co-owners consent to a mutual buyout
Standard solo-refinance qualification on the keeping spouse's own income
Registration of the departing spouse's discharge from title on closing
№ 05

The outcome

The refinance funded at 4.95%, with total debt service on the keeping spouse's income alone at 38.6%.

Because this file is uninsured, CMHC's ratio maximums do not apply directly; the 38.6% figure is informational. Had either spouse not consented to a buyout, the agreement's own term -- not a divorce court -- would have controlled how long the exit had to wait.

What to take from this file

  • 01Family patrimony covers the family residence, not every property a couple co-owns. A second property, like a rental cottage, is governed by ordinary co-ownership rules -- check what those actually say before assuming the divorce settlement reaches it.
  • 02A convention d'indivision's fixed term survives a divorce exactly as written. Nothing about ending a marriage cancels a separate contract between co-owners.
  • 03Absent mutual consent, a co-owner bound by an unexpired agreement cannot simply force a sale. Confirm the term's actual expiry before assuming an exit is available on demand.
  • 04Ask whether a co-owned second property carries its own registered agreement early. It can control the exit timeline more than the divorce itself does.

Sources

Every regulatory figure in this file traces to one of these primary sources. Client details and anything that varies by lender are illustrative, as flagged below.

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

  • 4.95% contract rate — rates move daily; not a quote.
  • the convention d'indivision's own term and its 50/50 split — every indivision agreement is negotiated individually between the co-owners; neither the term length nor the share split follows a formula.
  • the TDS figure — this is an uninsured buyout refinance, so there is no CMHC ratio ceiling -- the number is informational.
