Separation does NOT revoke your Will in Ontario. Learn the dangerous difference between 'Separated' and 'Divorced' when it comes to your legacy.
If you're separated but not divorced, your Will likely still names your ex-spouse as a beneficiary. This could result in them inheriting assets you intended for your children or new partner.
Legal Review: This article was medically and legally reviewed by Deepa Tailor, Senior Family Lawyer, to ensure accuracy regarding the Succession Law Reform Act (SLRA) and Bill 245 amendments.
In Ontario, simply separating from your spouse does NOT cancel your Will. If you die while "Separated" (but not Divorced), the Will stands, and your ex-partner could inherit everything you left them.
A final Divorce Order typically revokes gifts to a former spouse (treating them as if they had predeceased you).
As of 2022 (Bill 245), getting married no longer automatically revokes an existing Will.
Do not wait for the Divorce Order. You must update your Will immediately upon separation.
Key Takeaway: Your relationship status and your Will status are two separate legal matters in Ontario.
Your marital status at the time of death determines who inherits under your Will. Here's the legal breakdown:
| Status | The Rule | The Result |
|---|---|---|
Separated (Living apart, no Court Order) | The Will remains 100% valid | If your Will says "To my wife/husband," your ex gets the assets |
Divorced (Final Order issued) | Succession Law Reform Act s.17(2) applies | Gifts to the ex-spouse are revoked. They are treated as if they died before you |
Common Law (Separated) | Common Law spouses generally have no rights under a Will unless named specifically by name, not just by relationship | Depends entirely on the wording of the Will |
The law is clear: your Will reflects your intentions at the time it was written, not your current relationship status. Only a final Divorce Order or a new Will can change this reality.
Many separated couples believe their separation agreement protects their estate. Here's why that might not be enough:
"We signed a Separation Agreement where we both waived our rights to each other's estates, so my Will is safe."
Problem 1: Separation Agreements don't automatically override Wills
Problem 2: Your Estate Trustee may need to litigate to enforce the waiver
Problem 3: Legal costs could drain the estate while fighting the claim
Reality: Not necessarily. While a Separation Agreement creates a contract, it does not automatically change your Will. Your Estate Trustee might have to spend thousands in litigation to prove the Separation Agreement overrides the Will. It is safer to just write a new Will.
Solution 1: Update your Will immediately after separation
Solution 2: Name beneficiaries by name, not by relationship
Solution 3: Review and update beneficiaries on all accounts
Courts interpret legal documents literally, not based on what you "meant" or "intended." A Separation Agreement might provide grounds to challenge a Will, but it doesn't guarantee success.
The only way to guarantee your ex-spouse won't inherit is to write a new Will.
These real-world situations show how the divorce gap can create unexpected inheritance problems:
You separate amicably but don't finalize the divorce for 5 years to keep health insurance benefits.
If you die in Year 4, your ex inherits according to your old Will, potentially disinheriting your new partner or children from a subsequent relationship.
The longer you delay the divorce, the longer this vulnerability remains. Some couples delay divorce for years for financial reasons.
You move in with a new partner but haven't updated your Will. You're still legally married to your separated spouse.
If you die, your estranged spouse (who you are still legally married to) might have a stronger claim than your current common-law partner.
Legal spouses typically have stronger inheritance rights than common-law partners, even when separated.
Your Will leaves business shares to your "spouse." After separation, do you want your ex as a business partner with your new family?
You've moved out and your ex lives in the matrimonial home. Your Will still leaves the property to your "spouse."
You have children from multiple relationships. Your outdated Will doesn't reflect your current family structure.
In every scenario, the problem is the same: your Will reflects your past intentions, not your current reality. The law doesn't automatically update your estate plan when your life changes.
Solution: Update your Will immediately when your relationship status changes.
