Dying Inestate - If you die without a will (intestate) your assets are distributed according to provincial or territorial law
Examples (Ontario):
Age of majority: If your children are under the age of majority, their portion could be held with no access. At age 18, they could come into a significant inheritance
Marital Status: Some provinces and territories do not recognize common law partners under succession laws
Action Item: Speak with your lawyer to ensure your wishes are properly documented
