Two homes, one consent rule

a Kawartha Lakes cottage that was also a matrimonial home

A separating couple's cottage, held solely in one spouse's name, turned out to be a second matrimonial home under Ontario's Family Law Act -- meaning the other spouse's written consent was legally required to refinance it, even though that spouse never appeared on its title.

The client

A separating couple who owned a family cottage near Kawartha Lakes, held solely in the keeping spouse's name, needed to refinance it for $185,000 as part of their separation -- and discovered the cottage itself was a second matrimonial home, requiring a consent neither of them expected.

The problem

Under s.18(1) of Ontario's matrimonial home definition in the Family Law Act, a family can have more than one matrimonial home at the same time -- the textbook example is a cottage used regularly alongside the main residence. Because this cottage met that test, s.21(1) required the departing spouse's written consent before any new mortgage could register against it, even though that spouse had never appeared on its title.

What almost got missed

  • The cottage was held in the keeping spouse's name alone, with no obvious reason to seek anyone else's consent
  • The couple had used the cottage every summer for over a decade -- exactly the kind of regular family use that qualifies a second property as a matrimonial home
  • A mortgage registered against a matrimonial home without the required spousal consent risks being void against the non-consenting spouse

Nobody had done anything wrong on purpose. The cottage had simply never been thought of as anything but "the cottage."

The numbers

Once consent was in hand, the refinance itself was straightforward arithmetic.

Refinancing the cottageAmount
Cottage value$415,000
Refinance amount (44.6% LTV)$185,000
Total debt serviceFigure
Payment at the qualifying rate (6.85%), 25 years$1,279/mo
Property tax$290/mo
Heat (lender estimate)$110/mo
Car loan$240/mo
Total debt service27.0%

27.0% leaves comfortable room on the keeping spouse's income alone -- well within the range average home price history suggests families budget for carrying a second property. The real work in this file was the consent, not the ratios.

The solution

A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act recognized that a family cottage can be a matrimonial home in its own right, not just an ordinary second property.

First, confirmed with family counsel that the cottage met the s.18(1) test -- regular use by both spouses as a family residence, not simply occasional visits.

Second, obtained the departing spouse's written consent to the specific encumbrance before submitting the refinance for approval, rather than relying on the keeping spouse's sole signature on title.

Third, had the new lender's solicitor confirm the consent's own wording actually satisfied s.21(1), since a defective consent protects no one.

Standard refinance documentation qualifying on the keeping spouse's income alone
Solicitor's review confirming the consent satisfies s.21(1)
Registration held until the consent was confirmed valid
№ 05

The outcome

The refinance funded at 4.85% once the departing spouse's consent was on file, with total debt service settling at 27.0% on the keeping spouse's income alone.

Because this is an uninsured cottage refinance, CMHC's ratio maximums do not apply directly; the 27.0% figure is informational, showing how much room the file had once the consent question was resolved.

What to take from this file

  • 01A family cottage used regularly can be a SECOND matrimonial home under Ontario's FLA s.18(1) -- protected exactly like the main residence, no matter whose name is on its title.
  • 02The non-titled spouse's written consent under s.21(1) is required to encumber EITHER matrimonial home, not just the one everyone thinks of as "the" matrimonial home.
  • 03Ask early in any separation file whether a second property was used regularly enough to qualify. It is easy to miss because nothing on title flags it.
  • 04Get the consent in writing before, not after, submitting the file. A mortgage registered without it risks being void against the non-consenting spouse.

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

  • 4.85% contract rate — rates move daily; not a quote.
  • the $185,000 refinance amount — set by this family's own separation-related cash needs, not a formula.
  • the TDS figure — this is an uninsured cottage refinance, so there is no CMHC ratio ceiling -- the number is informational.
