Hello, valfor. Who has title to the property where you live? If it is a rental are both of youe names on the lease? Does Canada recognize common law marriages? Are both of your names on your son's certificate of birth? Who owns the personal property? Is some of the personal property jointly owned, like any vehicles? What about bank accounts and credit cards? Are they joint accounts.

While I hope you and he can work this out, it is good to be prepared. Maybe there will be other supportive posts with better ideas. Good luck.
