Can a Joint Tenancy Transfer Be Challenged as a Resulting Trust in Ontario?

What Is a Resulting Trust in an Ontario Estate Dispute?

A resulting trust arises when property is transferred to someone for free and the law presumes the recipient holds it for the benefit of the person who transferred it — not as their own. In Ontario estate disputes, this most often comes up when a parent puts an adult child on title to a home or bank account. The law starts from the position that the transfer was not a gift, and the child must prove otherwise.

The Supreme Court of Canada confirmed this framework in Pecore v. Pecore, 2007 SCC 17, which remains the leading authority. The child must show, on a balance of probabilities, that the parent genuinely intended a gift — not a loan or a trust arrangement.

How Do Courts Decide Whether a Property Transfer Was a Gift?

Courts look for three things: an intention to give without expecting anything in return, acceptance of the gift, and an actual transfer of the property. The most important factor is usually the transferor’s intention at the time of the transfer.

To assess that intention, courts prioritize evidence that existed at the time — documents prepared by lawyers, real estate files, and the terms of any will in effect when the transfer happened. Statements made by family members years later, especially those who would benefit financially from a different outcome, receive much less weight.

What Happened in This Hamilton Estate Case?

In Dzenekoj v. Mancini et al, 2026 ONSC 5307 (CanLII), a deceased Hamilton-area man had purchased a property in Caledonia and registered it in joint tenancy with one of his four adult children. He contributed all of the purchase price; she contributed nothing. After his death, the property passed to her by right of survivorship. Three of his other children disputed this, arguing the property should form part of the estate and be shared equally.

One of those children brought a motion seeking a preservation order — essentially a court order freezing the sale proceeds of the Caledonia property while the broader dispute was litigated. He also sought an order requiring the daughter to account for mortgage funds she had drawn on the property after the father’s death.

The court dismissed both requests. Justice Hilliard found that the evidence did not establish even a serious issue to be tried on the resulting trust question — a relatively low threshold. The contemporaneous evidence, including the real estate lawyer’s detailed notes and closing letter confirming the father had been advised of the consequences of joint tenancy and had confirmed his intention clearly, pointed strongly toward a gift.

Does Medical Evidence of Possible Incapacity Change the Analysis?

Not automatically — and this case illustrates why the quality of medical evidence matters enormously. The applicant filed an expert report from a physician who had never examined the deceased during his lifetime. The report was based entirely on a review of medical records and answered questions about whether certain conditions could have caused cognitive impairment — not whether they did.

Justice Hilliard gave that evidence no weight. The distinction between “possible” and “probable” is legally significant. Courts require evidence that something probably occurred, not merely that it was theoretically possible. There were no clinical findings of incapacity in the medical records, no referrals for capacity assessments, and no concerns documented by the health professionals who visited the deceased regularly.

This does not mean medical evidence is irrelevant in estate disputes — it means the evidence must meet a meaningful threshold. Our Ontario wills and estates lawyers regularly advise clients on what types of evidence courts actually find persuasive in capacity-related challenges.

What Is a Preservation Order and When Will a Court Grant One?

A preservation order is a court order that prevents a party from dealing with specific property or funds while litigation is ongoing. It is not as stringent as a Mareva injunction, but the moving party still must satisfy a three-part test: a claim to a specific fund, a serious issue to be tried regarding that claim, and a balance of convenience favouring the order.

In this case, the motion failed at the second stage. The court found that the evidence did not rise to the level of a serious issue to be tried — the bar the applicant needed to clear just to keep the motion alive. When the contemporaneous evidence is this consistent and this clearly documented, courts are reluctant to freeze property that legally belongs to someone else.

If you are involved in an estate dispute in the Hamilton or Burlington area, our Hamilton wills and estates team can help you assess whether the evidence in your situation supports a preservation motion.

What Role Does the Right of Survivorship Play in Estate Disputes?

When property is held in joint tenancy, the surviving co-owner automatically becomes the sole owner when the other co-owner dies. This happens outside the estate — the property does not pass through the will at all. That is why joint tenancy is sometimes used as an estate planning tool, but it is also why it becomes a flashpoint in estate litigation.

The right of survivorship vests when the joint tenancy is created, not at the time of death. This means that even if a parent later changes their will, the joint tenancy property is generally unaffected unless the joint tenancy itself is severed before death. In this case, the property was the only significant asset in the estate, which made the resulting trust question central to the entire dispute.

For families navigating these issues, speaking with a probate lawyer in Ontario early — ideally before a parent’s death — can help avoid costly litigation later.

Questions and Records to Discuss with a Lawyer

• What documents existed at the time of the property transfer, and do they reflect the transferor’s stated intentions?
• Were any capacity assessments conducted by treating health professionals, and what do those records show?
• Was independent legal advice obtained before the joint tenancy was registered?
• Are there earlier or later wills, and how do they treat the property or the beneficiary in question?
• What is the timeline of any changes to the title, mortgage, or estate documents relative to the deceased’s health history?
