Hi silverbed79,
Your spouse has no automatic interest in your home. The only assets and debts that must be automatically divided or shared are those that are owned or held jointly. Your spouse must prove that you were unjustly enriched by her in order to obtain an interest in any property owned by you, including RRSPs, other investments and your home.
Please see this link regarding
property division in common law separations. Please also take a look at this link regarding
division of the matrimonial home in common law relationships.
If you haven't already looked through this thread, please do so. Since you were together for 13 years, depending on the age of the children, you may also be looking at a child support obligation.
