The problem
Removing a name from title and releasing that person from the mortgage covenant are two separate legal steps. At the time of the divorce buyout, the first happened -- she came off title. The second never did: no one obtained a formal release from the original lender, so the $310,000 mortgage her ex now carries alone still names her, on paper, as a covenantor.
Two steps, only one of which happened
- ▸Title transfer: she came off title on the marital home, confirmed on the land registry
- ▸Covenant release: the original lender never formally released her from personal liability on the mortgage itself
- ▸Without the second step, that mortgage's payment still counts as her own active liability on any new application
She had every reason to believe coming off title settled the matter. It settled ownership. It never touched the debt.
The numbers
The gap between these two numbers is the entire lesson here, a pattern worth pricing correctly against broader average mortgage payment data before assuming a past buyout settled every liability.
| The old liability's real cost, if it still counted | Amount |
|---|---|
| New purchase's own qualifying payment | $2,351 |
| Old mortgage's own payment (still on her file, unreleased) | $2,014 |
| TDS with the old mortgage counted | 72.6% |
| TDS with the old mortgage properly excluded | 43.0% |
| Total debt service on the new purchase | Not released | Released |
|---|---|---|
| New mortgage qualifying payment | $2,351 | $2,351 |
| Property tax and heat | $355 | $355 |
| Old mortgage payment (if still counted) | $2,014 | $0 |
| TDS (+ $220 car loan) ÷ $6,800 income | 72.6% | 43.0% |
72.6% TDS is not a marginal decline -- it's not close. 43.0%, once the old liability was properly excluded, comfortably clears the file's own ceiling. The gap is the entire difference between a covenant that was and wasn't actually released.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act treated the old mortgage as an open question, not a settled one, from the first conversation.
First, contacted the original lender directly to confirm whether a formal covenant release had ever been processed at the time of the buyout. It hadn't -- only the title transfer had gone through.
Second, arranged for her ex to complete a fresh sole-name approval on the original mortgage with that same lender, formally releasing her covenant as part of that process. A step distinct from the original spousal buyout itself, which had settled ownership but not liability.
Third, obtained written confirmation of the release before submitting her own new purchase file, rather than assume the lender would simply exclude the payment. A lender's own file has to actually show the release before it will stop counting the liability.
The outcome
Once the release was confirmed and documented, her new purchase funded at 4.90%, TDS 43.0% -- comfortably inside the file's own ceiling. A liability from a mortgage she no longer owned any part of, but had never actually stopped being personally liable for, until someone actually asked the lender.
Coming off title changes who owns a property. It does not, on its own, change who is personally liable for the mortgage registered against it -- that requires a separate, formal release from the lender.
What to take from this file
- 01Coming off title in a divorce buyout does not, by itself, release a departing spouse from the mortgage covenant. Those are two separate legal steps.
- 02Confirm directly with the original lender whether a formal covenant release was ever processed at the time of a past buyout. Don't assume it was.
- 03An unreleased covenant can resurface months or years later, on the departing spouse's own next mortgage application, as a full active liability.
- 04A lender's file has to actually document a release before it will exclude the old payment. Get it in writing, at the time of the buyout if possible.
