Yes, under the Ontario Succession Law Reform Act, an ex-spouse who was receiving or entitled to receive spousal support is considered a dependant. You generally have exactly six months from the date the probate certificate is issued to file a support claim against the deceased’s estate at the Superior Court of Justice.
When a marriage ends in divorce, most financial ties are eventually severed. However, if a court order or a separation agreement dictates that one party must pay ongoing spousal support, that financial obligation does not necessarily vanish when the paying spouse dies. In Ontario, estate law heavily intersects with family law to protect vulnerable individuals who relied on the deceased for financial survival.
Under Part V of Ontario’s Succession Law Reform Act (SLRA), a deceased person has a legal obligation to make adequate provision for their dependants. If your ex-spouse passes away and fails to leave enough money in their will (or through life insurance) to cover your ongoing support needs, you may be entitled to sue the estate for “dependants’ relief.” This process ensures that support obligations take priority over the inheritances of adult children or new partners.
Step-by-Step Process in Ontario
Whether the estate is being administered in Brampton, Hamilton, or Toronto, a dependants’ relief claim must be properly documented and filed through the Superior Court of Justice. Because estate litigation is notoriously complex, most applicants choose to retain a dedicated Ontario lawyer to navigate these steps.
Step 1: Confirm Your Status as a Dependant
The very first hurdle is proving that you meet the strict legal definition of a “dependant” under the SLRA. As an ex-spouse, you must demonstrate two things: first, that you were married to (or in a recognized common-law relationship with) the deceased; and second, that the deceased was either providing support or was legally required to provide support immediately before their death. A signed separation agreement or a final divorce order explicitly mentioning spousal support is the strongest evidence you can provide.
Step 2: Reviewing the Estate’s Value
Before launching a costly lawsuit, it is vital to know if there is actually any money to claim. Your lawyer will typically reach out to the Estate Trustee to request an inventory of the deceased’s assets. Interestingly, under Section 72 of the SLRA, certain assets that usually bypass the estate-like jointly held property or life insurance policies payable to someone else-can sometimes be “clawed back” into the estate to satisfy a dependants’ relief claim.
Step 3: Filing the Notice of Application
Once you confirm the estate has assets, you must formally commence litigation. You will file a Notice of Application and a detailed sworn Affidavit at your local Superior Court of Justice. Your Affidavit must outline your current financial needs, your monthly expenses, your age, your health, and the historical context of your spousal support arrangement. Filing these documents puts an immediate “freeze” on the estate, legally blocking the executor from distributing funds to heirs.
Step 4: Mediation and Court Resolution
Ontario courts heavily encourage settlement in estate disputes. Most dependants’ relief claims go through mandatory or voluntary mediation before ever seeing the inside of a courtroom. If mediation fails, a judge will review all the evidence and determine what amount of money constitutes “adequate support” for your specific situation. The judge has broad powers to order lump-sum payouts, ongoing monthly cheques from an estate trust, or the transfer of specific property.
How Much Does it Cost in Ontario?
Estate litigation can be incredibly expensive. While court filing fees are standard, hourly lawyer fees accumulate rapidly during contested disputes. Here is a breakdown of estimated costs in CAD as of June 2026.
| Court Filing Fee (Notice of Application) | $243 CAD |
| Lawyer Retainer | $5,000 – $10,000 CAD |
| Mediation Fees (Split with Estate) | $1,500 – $3,500 CAD |
| Full Trial Costs | $30,000 – $100,000+ CAD |
How Long Does the Process Take?
Time is of the essence in estate litigation. You have exactly six months from the day the Certificate of Appointment of Estate Trustee (probate) is issued to file your claim. If you miss this window, and the estate has already been distributed, recovering funds becomes nearly impossible. Once the application is filed, reaching a mediated settlement usually takes 6 to 12 months, whereas taking a case all the way to a final trial can easily take 2 to 3 years in Ontario.
Frequently Asked Questions (FAQ)
Does child support count for dependants’ relief?
Absolutely. Minor children, or adult children who are still enrolled in full-time education and relying on the deceased for support, are considered primary dependants under the SLRA. A claim can be made on their behalf for unpaid or future child support obligations.
Who pays my lawyer fees if I sue the estate?
Initially, you must fund your own legal representation. However, if your dependants’ relief claim is highly successful, the judge may order that a portion (or all) of your legal costs be reimbursed directly out of the estate’s funds. This is entirely at the court’s discretion.
Can common-law partners claim dependants’ relief?
Yes. In Ontario, if you lived together in a conjugal relationship for at least three years, or if you have a child together in a relationship of some permanence, you qualify as a “spouse” for the purposes of dependants’ relief under the SLRA.
What if the deceased left everything to a new spouse?
Your valid claim for support generally takes precedence over the inheritances of beneficiaries, including a new spouse. The court will look at the entire financial picture and may reduce the new spouse’s inheritance to ensure you receive the adequate support you are legally owed.
