What are the circumstances in which a plaintiff who was in a marriage-like relationship for a short period of time, purchased a home together and held title jointly with her partner?

In my view, the circumstances of this case are similar to those considered by Mr. Justice Rice in McArthur v. Dodgson, 2010 BCSC 1172. In that case, the plaintiff and defendant, who lived in a marriage-like relationship for a little less than two years, purchased a home together and held title jointly. After the relationship broke down the house was sold and the plaintiff initiated litigation asserting a half interest in the proceeds of sale. She argued that her presumptive half interest as a joint tenant could not be displaced, as she contributed money to the purchase of the property, maintained it as a homemaker and assumed equal liability for the mortgage.
