The client
A couple in Sorel-Tracy was separating, with their matrimonial home co-owned as to an undivided share by one spouse's minor child, who had inherited that share years earlier from a grandparent's succession -- entirely unconnected to the couple's own marriage or separation.

The problem
The buyout refinance needed to mortgage the whole property, including the minor's own undivided share -- but a parent cannot unilaterally grant a hypothec over a minor's immovable interest just because the parent is also that minor's tutor. Under the Civil Code's tutorship rules, a tutor administering a minor's property needs authorization before taking a step as significant as encumbering an immovable.
What the keeping parent could not do alone
- ▸Sign the new hypothec over the minor's own undivided share, acting only as parent
- ▸Assume that being the minor's tutor by default gave automatic authority to mortgage the minor's property
- ▸Proceed on the separation agreement's own terms without first securing the tutorship council's or the court's consent
The couple's own separation was the easy part of this file. Getting authority to sign for a nine-year-old who had never been part of the marriage at all was not.
The numbers
Once authorization to encumber the minor's share was in hand, funding the buyout itself was ordinary arithmetic.
| Funding the buyout | Amount |
|---|---|
| Departing spouse's buyout | $165,000 |
| Total debt service | Figure |
|---|---|
| Qualifying payment (6.80%), 25 years | $1,135/mo |
| Property tax | $300/mo |
| Heat (lender estimate) | $110/mo |
| Car loan | $240/mo |
| Total debt service | 25.1% |
25.1% leaves the keeping spouse comfortable room even before accounting for anything the minor's own inherited share might separately contribute, well within the range home price data suggests for a property at this value.
The solution
A courtier hypothécaire licensed under Quebec's Act respecting the distribution of financial products and services worked alongside a notary to treat the minor's share as its own legal question, separate from the couple's separation agreement.
First, confirmed the exact size and origin of the minor's undivided interest from the grandparent's succession documents, rather than assuming it away as a technicality.
Second, had the notary prepare the tutorship authorization application to the tutorship council -- escalating to the court where the council's own rules required it -- seeking consent to encumber the minor's share as part of the new hypothec.
Third, sequenced the authorization and the separation agreement together rather than in series, so neither one sat waiting on the other any longer than necessary.
The outcome
The buyout refinance funded at 4.80%, with the minor's own share validly encumbered under a properly authorized hypothec, at 25.1% total debt service.
Because this is an uninsured buyout refinance, CMHC's ratio maximums do not apply directly; the 25.1% figure is informational.
What to take from this file
- 01A minor's own property interest does not become mortgageable just because a parent is also the minor's tutor. Tutorship authorization from the tutorship council or the court is a separate step, not a formality that follows automatically.
- 02A minor's share can predate, and be entirely unconnected to, the marriage a divorce file is otherwise about. Trace where every undivided interest on title actually came from before assuming the couple owns the whole property between them.
- 03Sequence a tutorship authorization alongside the separation agreement, not after it. Running the two in parallel keeps one from silently blocking the other.
- 04This is a notary-and-authorization problem with straightforward arithmetic underneath it. Once the authority to sign exists, funding the buyout itself is no different from any other.

- ▸the $165,000 buyout figure — set by this couple's own separation agreement; every equalization is negotiated on its own facts, not by formula.
- ▸the TDS figure — this is an uninsured buyout refinance, so there is no CMHC ratio ceiling -- the number is informational.
