How Separation Agreements Affect Estate Planning and Wills in Ontario

What Happens to Wills After Separation?

When couples separate in Ontario, many mistakenly believe that the separation itself nullifies existing wills or beneficiary designations. However, under Ontario law, a legal separation does not revoke a will. This distinction is crucial for individuals drafting a separation agreement and planning their estate.

Separation vs. Divorce in Estate Law

In Ontario, the Succession Law Reform Act governs how estates are distributed. While a divorce can revoke specific entitlements of a former spouse under a will (such as the right to serve as executor or receive certain bequests), a mere separation has no such automatic effect. This means your ex-partner may still:

• Be named as the executor (estate trustee) of your will.
• Remain a beneficiary under your existing will.
• Retain rights under joint assets or survivorship clauses (such as joint bank accounts or property).

Without updating your will or addressing these details in your separation agreement, your ex-spouse could unintentionally inherit part—or even all—of your estate.

Effect on Beneficiary Designations, RRSPs, and Insurance Policies

Separation agreements often include clauses about financial obligations, but they rarely change beneficiary designations on registered assets unless explicitly stated and acted upon.

Key estate planning documents impacted include:

• RRSPs, RRIFs, and TFSAs: If your former partner is still listed as a beneficiary, they may still receive the funds, even after separation, unless you update the designation.
• Life Insurance Policies: Unless changed with the provider, your ex could receive the death benefit.
• Pensions and workplace benefits: Depending on the plan’s rules, your former spouse could be entitled to survivor benefits if the designation isn’t revised.

Some of these designations can be overridden in a properly drafted separation agreement, especially if it includes a release of claims to estate or insurance proceeds. However, to ensure enforceability, these provisions should be accompanied by updated forms with your financial institutions and insurance providers.

Clauses in Separation Agreements That Impact Your Estate

A well-drafted separation agreement in Ontario can significantly influence your estate plan. While separation doesn’t automatically change your will or beneficiary designations, specific clauses in the agreement can directly affect what happens to your assets and responsibilities after death.

Life Insurance Obligations

Many separation agreements include a clause that requires one or both parties to maintain life insurance to secure future spousal or child support payments. This provision ensures that in the event of a payor’s death:

• The surviving ex-spouse or children are financially protected.
• The insurance proceeds are used to satisfy ongoing support obligations.
• A specific beneficiary is named, often a trustee for the children or the other parent.

Failing to follow this clause—such as not naming the correct beneficiary—can result in litigation after death, especially if the estate tries to redirect funds intended for dependants.

Future Spousal or Child Support Clauses

Support obligations that extend beyond your lifetime are increasingly common in Ontario. If your agreement includes language that binds your estate to continue spousal or child support:

• Your estate must account for these liabilities when distributing assets.
• These obligations take priority over gifts to other beneficiaries.
• If insufficient provisions are made, the support recipient can bring a dependant’s relief claim under the Succession Law Reform Act.

A separation agreement should clarify whether support ends at death or continues via the estate, and whether any life insurance serves as fulfillment of that duty.

Property Rights or Survivorship Entitlements

Property that was jointly owned before separation—such as the matrimonial home—can present complications if not clearly addressed. Key considerations include:

• Survivorship Rights: Jointly held property (joint tenancy) passes automatically to the surviving owner unless severed. A separation agreement should specify whether this joint ownership is severed and how the property is to be divided or retained.
• Exclusive Possession and Transfer Clauses: If one party retains the home, the agreement should reflect this, and ownership should be updated on title.
• Division of Real Estate or Investment Assets: If equalization or division of assets is not finalized, unresolved claims can delay estate administration or trigger legal action.

Common Mistakes to Avoid

Even with a carefully drafted separation agreement in Ontario, there are several critical missteps that can compromise your estate plans. Many individuals assume that the legal separation itself takes care of future arrangements—but that’s not the case. Here are the most common mistakes you should avoid:

Not Updating Your Will after Signing a Separation Agreement

One of the most frequent and costly oversights is failing to revise your will after separation. While the separation agreement might outline financial obligations or property division, it does not override your will unless you update it.

Consequences of not updating your will include:

• Your ex-spouse remaining as executor or beneficiary.
• Conflict between the terms of your separation agreement and your outdated will.
• Delays and disputes during the estate administration process.

It’s essential to ensure that your will, powers of attorney, and other estate documents align with your current intentions and any obligations outlined in your separation agreement.

Assuming Separation Automatically Revokes Previous Designations

Another common mistake is believing that separation voids previous beneficiary designations—it does not. Beneficiary designations on financial accounts, insurance policies, RRSPs, and pensions must be manually updated with each institution.

Failure to update these can result in:

• Ex-spouses unintentionally receiving lump-sum benefits upon your death.
• Legal challenges from your current spouse, children, or other intended beneficiaries.
• Potential breaches of your separation agreement if it includes specific insurance or estate-related provisions.

Even if your separation agreement includes waivers or releases of estate claims, courts may still honour existing beneficiary designations if not properly changed.

When to Speak with Both Family and Estate Lawyers

In Ontario, separation agreements often intersect with estate planning, making it essential to involve both family law and estate planning lawyers to ensure your legal and financial affairs are properly aligned. This collaboration helps prevent unintended consequences and protects your loved ones in the future.

Coordinating Legal Advice between Family Law and Estate Planning

A family lawyer focuses on negotiating and drafting your separation agreement—covering issues like child support, spousal support, and property division. An estate lawyer ensures your will, beneficiary designations, and powers of attorney reflect those new obligations and protect your estate.

Here’s why joint legal coordination matters:

• Your estate lawyer needs to know what you’ve agreed to in the separation agreement (e.g. life insurance clauses or continuing support).
• Your family lawyer should understand how certain estate provisions (like survivorship rights or trusts for children) affect ongoing support and property distribution.
• Without this coordination, conflicting terms between your will and separation agreement can lead to legal disputes, delays, or court challenges after death.

Protecting Your Children and Heirs from Future Disputes

Poorly integrated legal documents can leave your children, dependants, or new spouse in a vulnerable position. Common problems include:

• Ambiguity over who controls your estate or receives insurance payouts.
• Unintended beneficiaries (like an ex-spouse who was never removed from your RRSP or life insurance).
• Legal claims from a former spouse if your estate fails to meet support obligations outlined in your separation agreement.

By working with both legal professionals:

• You reduce the risk of litigation between heirs and former spouses.
• You ensure your estate plan honours the separation agreement while protecting the people you care about.
• You create a clear, enforceable framework that aligns with Ontario law and reflects your current wishes.
