Your “matrimonial home” is a home where you were living together when you separated.
Both spouses have an equal right to stay in the house until you have an agreement that deals with it or until it is sold. You cannot sell or mortgage the property without the other spouse’s written consent even if the property is registered in your name only.
It is different for common-law spouses.The spouse who is the registered owner of the property can sell or mortgage the home without the consent of the other spouse. Also, the spouse who is not a registered owner of the property does not have an equal right to stay in the home.
