Understanding the 'Succession Law Reform Act' and why the government writes a Will for you if you don't.
This article was medically and legally reviewed by Deepa Tailor, Senior Family Lawyer, to ensure compliance with the latest Ontario 'Succession Law Reform Act' amendments (2025).
Dying without a Will is called dying "Intestate."
Your assets are distributed according to a strict government formula. You have zero say in who gets what.
As of recent amendments, a legally married spouse is entitled to the first $350,000 of the estate value off the top.
Common Law spouses have NO automatic rights to inheritance under Ontario Intestacy rules, regardless of how long you lived together.
Ontario's Succession Law Reform Act follows a strict hierarchy to determine who inherits your assets when you die without a Will.
Your legally married spouse receives 100% of the estate.
Simple and straightforward - everything goes to your surviving spouse.
The Spouse gets the first $350,000 (Preferential Share). The remainder is split between the spouse and children (50/50 if one child; 1/3 spouse and 2/3 children if multiple kids).
Complex calculations ensure both spouse and children are provided for.
The children divide the entire estate equally. If a child has predeceased you, their share goes to their children (your grandchildren).
Per stirpes distribution ensures fair treatment across generations.
The order of inheritance is: Parents → Siblings → Nieces/Nephews → Next of Kin. If no kin is found, the property escheats to the Crown (Government).
Complex family tree analysis required to determine rightful heirs.

One of the most dangerous misconceptions about Ontario inheritance law involves common-law relationships.
"We lived together for 20 years, so I automatically inherit his assets just like a wife."
Many couples believe long-term cohabitation creates automatic inheritance rights
This misconception leads to devastating financial consequences for surviving partners
Time lived together is irrelevant under Ontario law
Under Ontario's Succession Law Reform Act, 'Spouse' only refers to married couples.
A Common Law partner inherits $0 under Intestacy rules
They must sue the estate for 'Dependent Support' or 'Unjust Enrichment' to get anything
Legal battles are expensive, time-consuming, and never guaranteed
The only way for common-law partners to inherit automatically is through a valid Will or joint ownership of assets. Intestacy rules completely exclude them from inheritance, regardless of the relationship's duration or depth.
Don't leave your partner's financial security to chance or expensive litigation.
Since there is no Will naming an Executor, someone must apply to the court to be appointed 'Estate Trustee Without a Will'.
First priority goes to the legally married spouse. Common law partners can also apply but have no automatic inheritance rights.
If no spouse exists or the spouse declines, adult children of the deceased can apply to be Estate Trustee.
The deceased's parents can apply if no spouse or children are available or willing to act.
Brothers and sisters of the deceased are next in line if no other family members can or will act.
This process often requires posting an 'Administration Bond' (insurance) to protect the estate, which can be expensive and adds additional delays to an already complex process.
