Separation does not neatly divide legal regimes. Family law governs support, property and parenting. Estate law governs what happens on death. When those worlds overlap, particularly for separated spouses, the results can be surprising, and sometimes costly.
The common misconception is that once parties separate, their estate obligations fall away. They do not. Unless steps are taken, a separated spouse may still have rights under a will, under beneficiary designations and, in some cases, under the Succession Law Reform Act and the Family Law Act.
Separation is not divorce
In Ontario, separation alone does not revoke a will. A spouse named in a will remains entitled unless the will is changed or other legal steps are taken. Even after separation, a spouse may still:
- inherit under an existing will;
- be named as beneficiary on registered accounts or life insurance;
- hold rights as a joint tenant on property; and
- have standing to make claims against the estate.
Divorce changes some of these outcomes automatically. Separation does not.
For family law practitioners, this creates a gap that often goes unaddressed during the separation process.
Equalization and the election on death
One of the most significant overlaps arises where a separated spouse dies before property issues are resolved.
Under the Family Law Act, a surviving spouse may elect to take an equalization of net family property instead of what they would receive under the will. This election can be financially advantageous where the deceased spouse accumulated significant assets during the relationship.
The practical effect is that a will does not necessarily control the outcome. The surviving spouse can choose the route that provides the greater benefit.
Where separation has occurred but equalization has not been resolved, this risk remains live.
Support claims against the estate
Support obligations do not necessarily end on death. A separated spouse who was receiving, or entitled to receive, support may bring a claim for dependant’s relief under the Succession Law Reform Act.
The court will consider:
- the nature and duration of the relationship;
- the claimant’s financial circumstances;
- any existing support arrangements; and
- the moral and legal obligations of the deceased.
These claims can significantly alter the distribution of an estate, even where the will appears clear.
Beneficiary designations and joint assets
Many assets pass outside the will entirely. Registered accounts, pensions and life insurance policies are often governed by beneficiary designations. Real property may be held in joint tenancy.
If a separated spouse remains named as beneficiary, or remains on title, those assets may pass directly to them on death.
Separation agreements sometimes address these issues. Many do not.
The result can be that an estate plan is effectively undone by inaction.
The practical gap in separation planning
In practice, estate issues are often treated as secondary during a separation. The focus is on immediate concerns: parenting, support, possession of the home and interim arrangements.
That is understandable, but it creates risk.
A disciplined approach to separation should include:
- reviewing and updating wills;
- changing beneficiary designations where appropriate;
- considering whether joint tenancies should be severed; and
- addressing estate-related obligations in any separation agreement.
Without these steps, the legal consequences of separation may not reflect the parties’ intentions.
Agreements and finality
A properly drafted separation agreement can address many of these issues, including:
- waivers of inheritance rights;
- releases of equalization claims;
- confirmation of beneficiary designations; and
- provisions dealing with support on death.
However, the effectiveness of these clauses depends on careful drafting and full disclosure. Courts will scrutinize agreements, particularly where there is a power imbalance or concerns about fairness.
When things go wrong
The overlap between family and estate law often becomes visible only after death, when options are limited and positions are entrenched.
Common issues include:
- outdated wills that no longer reflect the parties’ circumstances;
- unresolved equalization claims;
- competing claims between a separated spouse and other beneficiaries; and
- unexpected transfers of assets through beneficiary designations or joint ownership.
These disputes are complex and often avoidable.
Getting it right
Separation is not just a family law event. It has immediate and ongoing estate implications.
For counsel, the key is to raise these issues early and integrate estate planning into the separation process. For clients, the key is to act on them.
Updating a will, reviewing beneficiary designations and addressing estate rights in a separation agreement are not secondary tasks. They are essential steps in bringing clarity and finality to the separation.
If you are separating, or have recently separated, legal advice should address both family and estate considerations. Addressing one without the other leaves unnecessary risk.
