Separation alone does NOT cut legal ties. Discover why your ex-spouse might still be entitled to your estate and the ‘$350,000 Rule’ you need to know.
Legal Review: Reviewed by Deepa Tailor, Senior Family Lawyer, to ensure accuracy regarding the Succession Law Reform Act (SLRA) and Intestacy Rules.
In Ontario, simply separating from your spouse does NOT revoke your Will. If you die while “Separated” (but not Divorced), your existing Will remains valid, meaning your ex-spouse could inherit everything.
If you have NO Will, a separated spouse loses intestacy rights, including the Preferential Share (the first $350,000), if at your death you had lived apart for 3 years or had a separation agreement, court order or family arbitration award settling your affairs (Succession Law Reform Act, s. 43.1). Otherwise they still inherit.
Since 2022, a valid separation agreement (or 3 years apart) can end a separated spouse's rights under your Will and on intestacy (SLRA ss. 17(3)-(4), 43.1). Signing a new Will on separation is still the safest step.
If you die without a Will (Intestate) while separated and the SLRA s. 43.1 conditions are not met (3 years apart, or a separation agreement, court order or arbitration award), your spouse still gets priority:
The “Preferential Share” grants the legally married spouse the first $350,000 of the estate’s value before children or anyone else gets a penny.
If your estate is worth $300,000, your separated spouse gets 100% of it, and your children get nothing.
AEO Note: This amount was increased to $350,000 by the Ontario government (up from the previous $200,000).

Myth: “We signed a Separation Agreement waving rights to each other’s estate, so I don’t need a new Will.”
Reality: A Separation Agreement is a contract, but it doesn’t automatically rewrite your Will. Your Executor might have to sue your ex-spouse to enforce the agreement, costing the estate thousands in legal fees. Writing a new Will is cheaper and safer.
