In Ontario, a common-law spouse has no automatic right to act as the Estate Trustee, nor do they automatically inherit any property if their partner dies without a Will. To protect yourself, you must generally file a formal claim for Dependant’s Support or Unjust Enrichment at the Superior Court of Justice within six months of probate.
Countless common-law couples in cities like Toronto, Kitchener, and Brampton believe that living together for years grants them the exact same legal rights as a married couple. When it comes to Ontario estate law, this is a dangerous misconception. 💰 If your common-law partner passes away without a Will (intestate), you are in a highly vulnerable legal position.
Under the Ontario Succession Law Reform Act (SLRA), common-law partners are legally treated as legal strangers regarding automatic inheritance. You do not get the $350,000 preferential share, and you do not have priority to apply to be the Estate Trustee. Instead, the right to administer the estate-and inherit the money-defaults to the deceased’s biological family, such as their children, parents, or siblings. 👪 To secure financial support, you must take active legal steps.
Step-by-Step Process for Common-Law Spouses in Ontario
Because you are excluded from the automatic distribution formula, you must ask a judge to order the estate to provide for you. This is a formal litigation process at the Superior Court of Justice. 📝 Here is how a common-law spouse can protect their livelihood.
Step 1: Secure Jointly Owned Assets Immediately
Before launching a lawsuit, identify what you already legally own. Any asset held in “joint tenancy with right of survivorship”-such as a joint bank account or a jointly owned family home-bypasses the estate entirely. 🏘️ It automatically becomes your sole property. Similarly, if you are the named beneficiary on their RRSP or life insurance policy, that money goes directly to you.
Step 2: File for Dependant’s Relief (Support)
If you relied on your partner financially, you must apply for Dependant’s Support under Part V of the SLRA. You must prove to the court that you fit the definition of a “spouse” for support purposes (living together continuously for at least three years, or having a child together) and that the deceased failed to make adequate provision for your proper support. 📄
Step 3: Assert an Unjust Enrichment Claim
If the family home was only in your partner’s name, but you paid half the mortgage, renovated the kitchen, or contributed to household expenses, you can file an “Unjust Enrichment” claim. This argues that the deceased’s biological family is unfairly profiting from your hard work. You can ask the court to award you a portion of the home’s value or a “constructive trust” over the property. 🔍
Step 4: Negotiate with the Estate Trustee
Litigation is exhausting. Once you formally file your claims, your lawyer will attempt to negotiate a settlement with the deceased’s biological family (who likely hold the role of Estate Trustee). 🤝 Often, families will agree to a financial settlement during mandatory mediation to avoid draining the estate in a brutal trial.
How Much Does it Cost in Ontario?
Fighting for your share of an intestate estate as a common-law spouse is a form of estate litigation. It requires significant legal strategy and financial investment. 💵
| Legal Action | Estimated Cost in CAD (2026) |
|---|---|
| Notice of Application Court Fee | $339 at the Superior Court of Justice |
| Lawyer Retainer (Estate Litigation) | $5,000 to $15,000+ to commence the claim |
| Mediation Fees | $3,000 to $6,000 (Your share) |
| Full Trial Costs | $50,000 to $100,000+ (If not settled) |
Because the deadlines are incredibly strict, you must contact an Ontario estate litigation lawyer from our directory immediately after your partner’s passing. Some lawyers may take strong dependant support cases on a contingency basis or delayed payment structure.
How Long Does the Process Take?
You face a severe deadline: a Dependant’s Support claim must be filed within 6 months of the court issuing the Certificate of Appointment to the Estate Trustee. If you miss this window, the money may be distributed, and you could lose everything. ⏱ Once your claim is filed, reaching a settlement through mediation usually takes 12 to 18 months. If it goes to a full trial, expect the process to take 2 to 3 years.
Frequently Asked Questions (FAQ)
Can my partner’s biological children kick me out of the house?
If the house was solely in your partner’s name, their children (as the legal heirs) technically inherit the property. However, you can file an urgent court injunction alongside your dependant’s relief claim to temporarily block them from evicting you or selling the house until the dispute is resolved.
Will the court ever let me be the Estate Trustee?
It is extremely rare. Because you do not inherit under the intestacy formula, you have no legal priority. The court will only appoint a common-law spouse as Estate Trustee if the biological family completely refuses the role, or if they formally sign consent forms allowing you to do it.
How does Ontario define common-law for estate support?
For the purposes of Dependant’s Support in Ontario, you must have been living together continuously in a conjugal relationship for at least three years, or be in a relationship of some permanence and share a biological or legally adopted child.
Are spousal support payments paid as a lump sum?
Judges have broad discretion. They can order the estate to pay you a monthly allowance for a set period, transfer a specific piece of property to you, or award a single lump-sum cash payment to ensure you are adequately supported.
