Updating Your Will and Estate Plan After Divorce in Ontario: 2026 Complete Guide

By Antonio G. Jimenez, Esq.Ontario18 min read

At a Glance

Residency requirement:
The federal Divorce Act (s. 3) requires that either spouse have been ordinarily resident in Ontario for at least one year immediately before the application is made. "Ordinarily resident" means your habitual and customary home, not just temporary presence. You may file earlier, but the one-year residency must be met at the time of application.
Filing fee:
$450–$650
Waiting period:
The Canadian Divorce Act requires one year of separation before a divorce order can be granted. There is no additional waiting period after filing — the application can be filed at any time, but the divorce judgment will not issue until the one-year mark. The separation clock starts from the date of living separate and apart.

Under Ontario law, divorce automatically revokes gifts to your former spouse in your will pursuant to Succession Law Reform Act, R.S.O. 1990, c. S.26, s. 17, but this protection does not extend to beneficiary designations on RRSPs, TFSAs, life insurance policies, or jointly-held property. If you fail to update these designations manually, your ex-spouse could inherit hundreds of thousands of dollars even years after your divorce is finalized. Estate planning after divorce in Ontario typically costs $1,000 to $2,500 for a complete update including a new will, powers of attorney, and beneficiary designation reviews.

How Divorce Affects Your Will Under Ontario Law

Under Succession Law Reform Act, R.S.O. 1990, c. S.26, s. 17(2), divorce automatically revokes three specific provisions in your will: any gift or devise to your former spouse, any appointment of your former spouse as executor or trustee, and any general or special power of appointment conferred upon your former spouse. The law treats your former spouse as if they predeceased you, meaning any gifts intended for them pass to alternate beneficiaries named in your will or, if none exist, fall into the residue of your estate.

This automatic revocation applies only upon the granting of a final divorce judgment. During the separation period before divorce is finalized, your will remains fully effective as originally written unless you take steps to change it. Ontario courts have consistently held that the SLRA s. 17 revocation is automatic and does not require any action on your part once the divorce is granted.

However, this automatic protection has significant limitations. The revocation only affects provisions directly benefiting your former spouse. If your will names your former spouse's family members as beneficiaries, those gifts remain valid. Additionally, if your will contains language indicating a contrary intention, such as stating that gifts to your spouse should survive divorce, the automatic revocation may not apply.

The 3-Year Separation Rule (2022 Amendment)

Ontario introduced groundbreaking changes to estate law effective January 1, 2022, through amendments to the Succession Law Reform Act. Under the new 3-year separation rule, spouses who have lived separate and apart for at least three continuous years immediately before death are treated the same as divorced couples for estate purposes. This means gifts to a separated spouse in the will are automatically revoked without requiring a formal divorce.

The 3-year rule also applies if the spouses have entered into a valid separation agreement or if a court order or family arbitration award has been made dealing with their rights and obligations arising from the marriage breakdown. Since this rule took effect in 2022, the first three-year clocks expired in 2025, making this one of the most consequential estate planning developments for Ontario families in 2026.

The separated spouse loses inheritance rights under intestacy as well. If you die without a will after meeting the 3-year separation threshold, your separated spouse is treated as if they predeceased you for purposes of distributing your estate. This can redirect your assets to your children, parents, or other relatives instead of your estranged spouse.

Critical Gap: Beneficiary Designations Are NOT Revoked

Divorce in Ontario does not automatically revoke beneficiary designations on registered accounts or life insurance policies. Under Ontario Insurance Act, R.S.O. 1990, c. I.8, s. 190, the beneficiary designated on a life insurance policy remains entitled to the proceeds unless you execute a formal change of beneficiary form with the insurance company. Prior to the 1970s, Ontario law automatically revoked spousal beneficiary designations upon divorce, but that provision was repealed and courts have concluded the legislature intended designations to continue until altered.

Consider this scenario: You named your spouse as beneficiary of your $500,000 life insurance policy 15 years ago when you married. You divorce and remarry. You create a new will leaving everything to your new spouse. You die. Your ex-spouse receives the full $500,000 life insurance proceeds because you never changed the beneficiary designation form. Your new spouse inherits only what passes through your will.

Assets Requiring Manual Beneficiary Updates

The following assets pass outside your will and require separate beneficiary designation changes after divorce:

  • Registered Retirement Savings Plans (RRSPs)
  • Registered Retirement Income Funds (RRIFs)
  • Tax-Free Savings Accounts (TFSAs)
  • Locked-In Retirement Accounts (LIRAs)
  • Life Insurance Policies
  • Workplace Pension Plans
  • Group Registered Retirement Savings Plans

To update these designations, you must contact each financial institution directly and complete their specific beneficiary change forms. A general statement in your will that all beneficiary designations should favour your new spouse is not sufficient under Ontario law. Each institution requires its own documentation following their internal procedures.

Joint Property and Right of Survivorship

Property held in joint tenancy with right of survivorship passes automatically to the surviving joint owner upon death, completely bypassing your will and estate. If you still own real estate, bank accounts, or investment accounts jointly with your former spouse after divorce, these assets transfer to them immediately upon your death regardless of what your will states.

Ontario's Succession Law Reform Act and automatic revocation provisions do not affect joint tenancy survivorship rights. The property never enters your estate, so estate law rules simply do not apply. You must sever the joint tenancy during your lifetime to prevent this automatic transfer.

Severing a joint tenancy on real property in Ontario requires registering a severance document on title. For jointly held bank accounts and investments, you must work with the financial institution to change the account registration. Many couples address joint property division in their separation agreement, but executing the actual transfers and title changes often takes months. Until those changes are complete, survivorship rights remain in effect.

Powers of Attorney: No Automatic Revocation

Ontario's Substitute Decisions Act, 1992, S.O. 1992, c. 30 governs powers of attorney and does not automatically revoke your former spouse's authority upon divorce or separation. If you granted your spouse a Continuing Power of Attorney for Property or a Power of Attorney for Personal Care, they retain full authority to act on your behalf unless you explicitly revoke those documents.

This creates serious risks if you become incapacitated after separation but before updating your documents. Your estranged spouse could make financial decisions, sell property, or even make healthcare decisions on your behalf. In high-conflict divorces, this potential for abuse is particularly concerning.

To revoke a power of attorney in Ontario, you must prepare a written revocation document that identifies the specific power of attorney being cancelled, states clearly that you are revoking it, and is signed and witnessed following the same requirements as the original document. You must then notify your former attorney in writing and inform all financial institutions, healthcare providers, and other organizations that previously relied on the original document.

Unique to Ontario, the Substitute Decisions Act does not automatically revoke an existing Continuing Power of Attorney for Property when you create a new one unless your new document explicitly states that all prior powers of attorney are revoked. Without this explicit language, you could have two valid powers of attorney with two different attorneys.

Trusts and Divorce: Updating Beneficiary Provisions

If you established a revocable inter vivos trust (living trust) during your marriage, you retain full authority to change the trust terms and beneficiaries after divorce. As the settlor of a revocable trust, you can remove your former spouse as beneficiary, change successor trustees, and modify distribution provisions at any time during your lifetime. Upon your death, the trust becomes irrevocable and its terms are locked.

For irrevocable trusts, modification is substantially more difficult. Generally, irrevocable trusts cannot be changed except through a court application demonstrating that the trust purposes have failed or that all beneficiaries consent to the modification. If your former spouse is a beneficiary of an irrevocable trust you created, removing them typically requires their consent and possibly court approval.

Trusts created by third parties, such as your parents' family trust, are not affected by your divorce. Your interest as a beneficiary in someone else's trust is considered your separate property and is not subject to equalization under the Family Law Act. However, any income or distributions you received from the trust during the marriage may be included in net family property calculations.

The Family Law Act Election: What Separated Spouses Can Claim

Even after updating your estate plan, a surviving spouse may have rights under the Family Law Act, R.S.O. 1990, c. F.3, s. 6 that could redirect your assets. Under section 6, a surviving married spouse can elect between taking under the deceased's will (or intestacy) or claiming an equalization of net family properties as if the spouses had separated the day before death.

The equalization calculation compares each spouse's net family property and entitles the spouse with lesser property to one-half the difference. For example, if the deceased spouse accumulated $800,000 in net family property during the marriage and the surviving spouse accumulated $200,000, the surviving spouse could claim $300,000 (half of the $600,000 difference) through equalization instead of taking under the will.

The surviving spouse has only 6 months from the date of death to make this election and commence an application for equalization. If no election is made within this period, the surviving spouse is deemed to have elected to take under the will or intestacy. A guardian of property or attorney for property can make the election on behalf of an incapacitated surviving spouse.

This election right can be prevented by a valid domestic contract such as a marriage contract or separation agreement that waives equalization rights on death. Most comprehensive separation agreements include releases of claims under the Family Law Act, including the section 6 election right.

Estate Planning Checklist After Divorce

Complete estate planning after divorce in Ontario requires addressing each of the following items:

  1. Execute a new will that reflects your current wishes and family circumstances
  2. Revoke all existing powers of attorney and execute new ones naming trusted individuals
  3. Update RRSP, RRIF, and TFSA beneficiary designations with each financial institution
  4. Change life insurance policy beneficiaries by completing insurer forms
  5. Update pension plan beneficiary designations with your employer or pension administrator
  6. Address joint property ownership through severance or transfer
  7. Review any trusts you created and update beneficiary provisions
  8. Cancel your former spouse's access to safe deposit boxes and financial accounts
  9. Update digital asset and online account succession plans
  10. Confirm your separation agreement includes releases of Family Law Act claims

The typical timeline for completing a comprehensive estate plan update after divorce is 30 to 60 days after your separation agreement is signed. Most estate planning lawyers recommend updating documents during the separation period rather than waiting for the divorce to be finalized, particularly if significant assets are involved.

Cost of Estate Planning After Divorce in Ontario

Estate planning after divorce in Ontario typically costs between $1,000 and $2,500 for a complete package including a new will and both powers of attorney. This cost varies based on the complexity of your estate and the number of beneficiary designations requiring updates.

ServiceTypical Cost (2026)
Simple Will$300-$500
Complex Will (multiple properties, trusts)$1,500-$5,000
Will + Both POAs Package$900-$2,500
Beneficiary Designation UpdatesTypically free with institutions
Joint Tenancy Severance (real property)$500-$1,500
Trust Amendment$500-$2,500
Online Will Services$99-$300

As of June 2026, most experienced estate planning lawyers in the Greater Toronto Area charge between $350 and $650 per hour. A straightforward estate plan update typically requires 3-5 hours of lawyer time. Complex situations involving business interests, real property in multiple jurisdictions, or trust modifications can require significantly more time.

Online platforms like Willful offer more affordable options starting around $99 to $300 for basic documents, though these may not be appropriate for complex estates or situations requiring customized provisions. Independent legal advice on separation agreements, which often addresses estate planning issues, typically costs $1,000 to $2,000 per spouse.

Common Mistakes to Avoid

The most common estate planning errors after divorce in Ontario include:

Assuming divorce automatically updates everything: While the SLRA s. 17 revokes will provisions, registered accounts, insurance policies, and joint property require separate action. A 2024 Ontario Superior Court decision confirmed that an ex-spouse received $425,000 in RRSP proceeds because the deceased never updated the beneficiary designation despite creating a new will.

Waiting until divorce is final: Estate planning emergencies do not wait for divorce proceedings. If you become incapacitated or die during separation, your estranged spouse may still have significant control and inheritance rights. Update your documents during separation.

Forgetting about digital assets: Email accounts, social media profiles, cryptocurrency wallets, and online banking access need updated succession plans. Many people name their spouse as a digital executor or account recovery contact.

Overlooking pension beneficiaries: Workplace pension plans often have specific rules about spousal beneficiaries, and some require spousal consent to change the designation. Contact your employer's benefits administrator promptly after separation.

Not coordinating with your separation agreement: Your estate plan and separation agreement should work together. If your separation agreement requires you to maintain life insurance for child or spousal support obligations, your estate planning documents must reflect those requirements.

Working With an Estate Planning Lawyer

After divorce, consulting with an estate planning lawyer ensures your documents are properly coordinated and legally effective. When meeting with your lawyer, bring the following documents:

  • Your current will and powers of attorney
  • Your separation agreement (signed or draft)
  • Recent financial statements for all registered accounts (RRSPs, TFSAs, RRIFs)
  • Life insurance policy documents showing current beneficiary designations
  • Pension plan summary and beneficiary information
  • Real property deeds showing current ownership
  • Any trust documents you created or benefit from
  • Divorce judgment (if divorce is finalized)

Your estate planning lawyer should coordinate with your family law lawyer to ensure consistency between your separation agreement and estate documents. Many people use different lawyers for these matters, making communication between them essential.

For straightforward situations with modest estates and no ongoing support obligations, some individuals successfully use online will services combined with direct contact with financial institutions for beneficiary updates. However, any situation involving minor children, blended families, business interests, or assets over $500,000 benefits from professional legal guidance.

Frequently Asked Questions

Does divorce automatically revoke my will in Ontario?

No, divorce does not revoke your entire will. Under SLRA s. 17(2), divorce automatically revokes only three specific provisions: gifts to your former spouse, their appointment as executor or trustee, and any powers of appointment granted to them. All other will provisions remain valid, and your will continues to govern your estate distribution. You should still create a new will to reflect your changed circumstances and name new executors and beneficiaries.

Will my ex-spouse automatically lose their RRSP and life insurance if we divorce?

No, beneficiary designations on RRSPs, TFSAs, RRIFs, life insurance policies, and pension plans are NOT automatically revoked by divorce in Ontario. You must contact each financial institution and insurance company directly to complete new beneficiary designation forms. If you fail to update these designations, your ex-spouse will receive the proceeds regardless of what your will says. Prior to the 1970s, Ontario law automatically revoked spousal insurance beneficiary designations, but this protection was repealed.

How soon after separation should I update my estate plan?

You should update your estate plan within 30 days of signing a separation agreement. If you become incapacitated or die during separation before updating your documents, your estranged spouse may retain significant control through existing powers of attorney and could inherit through your will. The risk is particularly acute in high-conflict situations. Many estate planning lawyers offer expedited services for clients going through divorce.

What happens to joint property if I die before changing the title?

Property held in joint tenancy with right of survivorship passes automatically to the surviving joint owner upon death, completely bypassing your will. If you still hold real estate, bank accounts, or investments jointly with your ex-spouse, they will receive those assets immediately upon your death regardless of your divorce status or will provisions. You must sever the joint tenancy during your lifetime to prevent this automatic transfer.

Does my ex-spouse lose their power of attorney authority when we divorce?

No, divorce does not automatically revoke powers of attorney in Ontario. Under the Substitute Decisions Act, 1992, your former spouse retains full authority to make financial and personal care decisions on your behalf unless you explicitly revoke those documents in writing. You must execute a formal revocation document, notify your former spouse, and inform all financial institutions and healthcare providers.

Can my separated spouse still claim against my estate?

Yes, a separated spouse who is not yet divorced retains significant rights under the Family Law Act, R.S.O. 1990, c. F.3, s. 6. They can elect to receive an equalization payment instead of inheriting under your will, potentially claiming 50% of the net family property accumulated during the marriage. This election must be made within 6 months of death. The 3-year separation rule revokes will gifts but does not eliminate the FLA election right.

How much does it cost to update my estate plan after divorce?

A complete estate plan update in Ontario, including a new will and both powers of attorney, typically costs $1,000 to $2,500 with an estate planning lawyer. Simple wills alone cost $300 to $500, while complex wills involving trusts or business interests can cost $1,500 to $5,000 or more. Updating beneficiary designations with financial institutions is usually free. Online will services offer lower-cost alternatives starting around $99 to $300.

What is the 3-year separation rule for estate planning?

Effective January 1, 2022, Ontario law treats spouses who have lived separate and apart for at least 3 continuous years as divorced for estate purposes under the SLRA. Gifts to the separated spouse in the will are automatically revoked, their executor appointment is cancelled, and they lose intestacy inheritance rights. This rule also applies if the spouses have a valid separation agreement or court order dealing with their rights upon separation.

Do I need to update my trust after divorce?

If you created a revocable living trust during your marriage, you should update it to remove your former spouse as beneficiary and potentially change successor trustees. As settlor of a revocable trust, you have full authority to make these changes at any time. For irrevocable trusts, modification typically requires consent of all beneficiaries and possibly court approval. Your interest as beneficiary in a trust created by someone else is not affected by your divorce.

Should I update my will during separation or wait for divorce?

Update your will during separation rather than waiting for the divorce to be finalized. If you die during separation before divorce is granted, your estranged spouse could inherit under your existing will unless you meet the 3-year separation threshold. Additionally, if you become incapacitated, your estranged spouse could retain authority under existing powers of attorney. Most estate planning lawyers recommend completing all estate document updates within 30 days of signing a separation agreement.
