The respondent and the deceased held title to their matrimonial home as joint tenants.
They were in the process of separating and dividing their matrimonial assets when the deceased died.
The respondent claimed exclusive ownership of the home through the right of survivorship.
The deceased's estate trustees brought an application for a declaration that the estate was entitled to an undivided, one-half interest in the matrimonial home, arguing the joint tenancy had been severed by a course of dealing.
The application judge dismissed the application.
The Court of Appeal allowed the appeal, finding that the application judge erred by adopting a category-based approach to the course of dealing test.
The spouses' conduct, including negotiating an equal division of assets and opening separate bank accounts, demonstrated they were mutually treating their co-ownership as a tenancy in common.
