Under the old Ontario law, separation alone — no matter how long — did not affect your Will or your right to inherit from your spouse. A couple could be separated for a decade, living separate lives with new partners, and the estranged spouse would still inherit everything if the other died without updating their estate. The law treated separation as if it hadn't happened.
That changed on January 1, 2025. Ontario amended the Succession Law Reform Act (SLRA) to fix this gap. Separated spouses are now largely treated the same as divorced spouses for inheritance purposes — automatically, in certain circumstances.
Here's what that means, when it applies, and where a significant gap remains.
The 2025 Change in Plain Language
Before January 1, 2025: Separation alone had no effect on inheritance rights. A separated spouse kept all Will entitlements and intestate rights until a legal divorce was granted.
After January 1, 2025: A separated spouse who meets Ontario's new statutory definition of "separated" is treated like a divorced spouse. Gifts in a Will are automatically revoked, and there are no intestate inheritance rights.
The gap that remains: The new rules cover Wills and intestate succession. They do not automatically update beneficiary designations on RRSPs, TFSAs, life insurance, or RRIFs. Those accounts pass outside the Will — and the SLRA doesn't touch them.
What the Old Law Got Wrong
The scenario the old law created was genuinely absurd.
Imagine a couple who separated years ago. They have new partners. Their finances are completely separate. They haven't spoken in years. Neither has updated their Will — it still names the other as beneficiary, which seemed fine when it was written but now reflects a relationship that no longer exists in any meaningful sense.
Under the old Ontario law, if either person died, the estranged spouse would inherit. Full stop. Years of physical separation, separate households, separate relationships — none of it changed the legal entitlement. Only a finalized divorce would have removed the inheritance rights, and lots of long-separated Ontarians never got around to the paperwork.
The result: people's estates went to someone they hadn't lived with in years, while the people who were actually part of their lives — new partners, children from new relationships — had no automatic claim.
This wasn't a theoretical problem. It was a documented pattern. And Ontario's legislature finally addressed it.
What the 2025 SLRA Amendments Changed
As of January 1, 2025, Ontario amended the Succession Law Reform Act so that separated spouses who meet the new statutory definition are treated the same as divorced spouses for inheritance purposes.
Two things now happen automatically when spouses qualify as "separated" under the new rules:
Any bequest, executor appointment, or trustee role given to a separated spouse in a Will is treated as if that spouse died before the person who made the Will. They receive nothing under the Will — unless the Will explicitly states that it applies even after separation.
If you die without a Will, a separated spouse is not entitled to inherit from your estate. The same treatment a divorced spouse received under the old law now applies to separated spouses who meet the threshold.
Both changes happen automatically by operation of law — you don't have to take any steps to trigger them. If the conditions are met, the inheritance rights are stripped.
When Are You "Separated" Under the New Rules?
The 2025 amendments don't define "separated" as simply living apart. A spouse qualifies as separated — and loses automatic inheritance rights — if any one of the following existed before death:
- Living separate and apart for at least three years due to marriage breakdown
- A valid separation agreement is in place
- A court order resolving marital issues exists
- An arbitration award addressing spousal rights exists
Only one of these needs to be true. And critically, this is an "any one" test — not a checklist you need to complete. A couple who separated last year and have already signed a separation agreement already satisfy the condition through that agreement alone, regardless of how long they've been apart.
Examples of How the Threshold Works
Three-year separation, no agreement: Couple separated in 2021, never signed an agreement, no court order. By 2025, they've been apart for over three years. The three-year condition is satisfied — separated spouse loses automatic inheritance rights under the new rules.
Recent separation with agreement: Couple separated in late 2024 and signed a separation agreement in January 2025. They've been apart less than three years. But the separation agreement itself satisfies one of the four conditions — separated spouse immediately loses automatic inheritance rights.
Recent separation, no agreement yet: Couple separated in late 2025, no agreement signed, no court order. They've been apart less than three years. None of the four conditions are yet satisfied — the old inheritance exposure still applies until they cross the three-year threshold or sign an agreement.
The Separation Agreement Connection
This is the piece most people miss: a separation agreement itself is one of the four triggering conditions.
The moment you sign a valid separation agreement, your spouse loses their automatic entitlement to inherit from your estate. Not after three years. Not after a court order. Immediately — because the agreement is itself one of the conditions that strips the inheritance rights.
This cuts both ways:
- If you want to remove your separated spouse's inheritance rights quickly, signing a separation agreement accomplishes that — along with everything else the agreement covers.
- If you haven't signed an agreement yet and you die before the three-year mark, your separated spouse may still inherit unless you've updated your Will in the meantime.
The Gap the 2025 Changes Didn't Fix
The SLRA amendments cover Wills and intestate succession. That's significant. But there's an entire category of assets they don't touch — and it's the category where most Canadians hold the bulk of their savings.
Beneficiary designations are not affected by the 2025 changes.
Life insurance policies, RRSPs, TFSAs, RRIFs — these assets pass directly to whoever is named as beneficiary, completely outside the Will. The SLRA doesn't govern them. Which means a separated spouse who remains named as beneficiary on your RRSP will receive those funds even if the new rules have stripped all of their Will entitlements.
The 2025 SLRA amendments can protect your estate from an unwanted inheritance claim. They cannot undo a beneficiary designation you haven't updated.
Joint ownership arrangements and trust structures are similarly outside the SLRA's scope. These also pass outside the Will and are not affected by the 2025 amendments.
What the Old and New Laws Mean Side by Side
| Situation | Before Jan 1, 2025 | After Jan 1, 2025 |
|---|---|---|
| Separated, no agreement, under 3 years | Spouse inherits from Will and intestate | Spouse still inherits (conditions not met) |
| Separated 3+ years, no agreement | Spouse inherits from Will and intestate | Spouse loses Will gifts and intestate rights |
| Valid separation agreement signed | Spouse inherits from Will and intestate | Spouse loses Will gifts and intestate rights |
| Court order or arbitration award | Spouse inherits from Will and intestate | Spouse loses Will gifts and intestate rights |
| RRSP/TFSA beneficiary designation | Goes to named beneficiary (outside Will) | Still goes to named beneficiary — SLRA does not apply |
| Divorced | Will read as if ex-spouse died before testator | Same — no change |
What You Should Do Now
The 2025 changes are a significant improvement over the old law. But they don't eliminate the need to take action. They're a safety net — and a partial one.
Update your Will. Even if the SLRA rules now automatically strip your separated spouse's entitlements in certain circumstances, don't rely on the statute to distribute your estate the way you actually want. A properly drafted Will is the only way to ensure your assets go to the people you intend. Do not leave it to the law to decide.
Review and update beneficiary designations immediately. This is the one the SLRA doesn't cover, and it's urgent. Check the beneficiary designation on every registered account you hold — RRSP, TFSA, RRIF — and every life insurance policy. If your separated spouse is still named, change it. Do this separately from updating your Will; it requires direct contact with each institution.
Don't assume you're covered if you separated recently. The 2025 amendments require a threshold to be met. If you separated less than three years ago and have no agreement and no court order, the conditions may not yet be satisfied. Your separated spouse may still have rights under the new law's framework. Update your Will and beneficiary designations now rather than waiting for the three-year mark.
If you have a new partner, get advice. The intersection of new relationships, separated-but-not-divorced status, and estate planning is complicated. The fact that Ontario law now treats separated spouses similarly to divorced spouses doesn't mean your estate is automatically in order. Consult an estate lawyer.
Frequently Asked Questions
Can a separated spouse still inherit in Ontario after the 2025 SLRA changes?
It depends on whether the separated spouse meets Ontario's new statutory definition of "separated." A separated spouse loses automatic Will gifts and intestate inheritance rights if any one of four conditions existed before death: living separate and apart for at least 3 years, a valid separation agreement is in place, a court order resolving marital issues exists, or an arbitration award addressing spousal rights exists. If none of those conditions are met — for example, a couple who recently separated with no agreement or court order — the old inheritance exposure still applies.
What did Ontario change about separated spouse inheritance in 2025?
As of January 1, 2025, Ontario amended the Succession Law Reform Act (SLRA) so that separated spouses are largely treated the same as divorced spouses for inheritance purposes. Before the change, separation alone — no matter how long — did not affect a Will or intestate rights. After the change, a spouse who qualifies as "separated" under the new definition automatically loses Will bequests and intestate inheritance rights, unless the Will explicitly states otherwise.
Does signing a separation agreement affect inheritance rights in Ontario?
Yes. A valid separation agreement is one of the four conditions that triggers the loss of automatic inheritance rights under the 2025 SLRA amendments. The moment a valid separation agreement is signed, the separated spouse loses their automatic entitlement to Will bequests and intestate inheritance — regardless of how long the couple has been separated. This makes the drafting of a separation agreement consequential for estate planning as well as family law.
Are beneficiary designations affected by the 2025 SLRA changes?
No. The 2025 SLRA amendments affect Wills and intestate succession only. They do not automatically update beneficiary designations on life insurance policies, RRSPs, TFSAs, or RRIFs. These assets pass outside the Will entirely — so the new law does not touch them. A separated spouse who remains named as beneficiary on your RRSP will still receive those funds. Beneficiary designations must be updated separately and deliberately.
What should I do about my Will after separating in Ontario?
Update it. Even if the 2025 SLRA rules automatically strip your separated spouse's Will entitlements, don't rely on the statute to handle your estate. A new Will ensures your assets go where you actually want them to go. Separately, review and update all beneficiary designations on registered accounts (RRSPs, TFSAs, RRIFs) and life insurance policies — these are not covered by the SLRA changes and must be changed manually.
