Two Siblings Challenge a Caregiver's Sole Inheritance

The situation

Amrit, a retail worker, got the call from his sister Fiona on a Tuesday morning: their mother had passed away in Woodstock after a long decline. He called his brother Raymond, a long-haul truck driver who was three days from home on a delivery run, and they agreed to meet once Raymond could get back. Their mother had made a will years earlier that split everything evenly between her three children. Nobody had reason to think that had changed.

Fiona had moved in with their mother about eighteen months before she died, after a fall made it unsafe for their mother to live alone. She managed medication, drove her to appointments, and handled the household bills. Amrit and Raymond, both living further away and working demanding schedules, visited when they could but leaned on Fiona for updates. It seemed like a reasonable arrangement at the time.

When the estate trustee named in the will — a lawyer their mother had used for years — reached out to the three siblings, Amrit and Raymond learned that a new will had been signed about seven months before their mother's death. It left the entire estate to Fiona. Nothing to either of them. The earlier will, the one dividing everything equally, had been revoked.

The suspicious will

Amrit and Raymond came to Treadstone Law with the new will in hand and a lot of questions. They were not disputing that Fiona had done real caregiving work. What troubled them was how the change had happened without either of them knowing, and how completely it favoured the one sibling who had daily access to their mother in her final months.

Ontario law lets a court set aside a will, in whole or in part, if it does not reflect the true wishes of the person who made it. One ground is undue influence: a will is invalid if someone used pressure, manipulation, or the trust placed in them to override the will-maker's own free choice, rather than simply persuading them through ordinary affection or argument. Proving undue influence is difficult. The person alleging it generally has to show the influence was strong enough to overpower the will-maker's own judgment, not just that the beneficiary had opportunity and motive. A caregiver who happens to inherit is not, on its own, proof of anything improper.

But the surrounding facts matter, and our team's first job was to gather them methodically. Reviewing the file, several things stood out. Their mother had used the same lawyer for two decades and had never mentioned wanting to change her will to that lawyer directly — the new will had been drafted by a different lawyer, arranged by Fiona, who drove their mother to the appointment and, according to the intake notes later obtained, stayed in the waiting room but had made the initial phone call to book it. Their mother's family doctor's records, obtained with the estate trustee's consent, showed a diagnosis of moderate cognitive impairment recorded about five months before the new will was signed, squarely inside the window when the new will was being prepared. And in the final year of her life, both Amrit and Raymond had noticed their mother becoming harder to reach — calls that used to happen weekly grew shorter and less frequent, and a planned visit from Raymond had twice been cancelled at the last minute for reasons that, in hindsight, were unclear.

None of this proved undue influence by itself. Together, it was enough to raise real questions about whether their mother had made the new will with a clear, independent mind, and whether she had understood and approved what it actually did.

What we did

1. Filed a notice of objection with the estate registrar. Before the new will could be formally proven and an estate trustee appointed under it, we filed the paperwork needed to flag the dispute, which paused the process and required Fiona, as the person seeking to rely on the will, to justify it if the matter proceeded further.
2. Requested the will file from the drafting lawyer. Under long-settled principles, a lawyer who prepares a will must produce their file when its validity is challenged. That file showed the appointment had been booked by phone by someone other than the client, that no one had screened for who was present during instructions, and that there was no attendance note confirming the lawyer had met privately with their mother, without Fiona in the room, to confirm the terms were truly her own idea.
3. Gathered medical and lay evidence of capacity and isolation. We obtained the family doctor's records with proper authorization, along with a short affidavit from a home care worker who had visited occasionally and recalled their mother seeming confused about which will was current. We also documented the pattern of reduced contact between their mother and her two other children in the months before the will was signed.
4. Explained the legal burden to both sides early. Once suspicious circumstances are shown — an unexplained departure from a person's known wishes, a beneficiary heavily involved in arranging the will, and questions about capacity or independence — Ontario courts require the person defending the will to prove the will-maker knew and approved its contents with a clear, informed mind. We set out this framework in early correspondence so Fiona's lawyer understood the evidentiary hill they would need to climb.
5. Proposed a structured settlement before trial. Litigating a will challenge to a full trial in the Superior Court can take well over a year and consume a meaningful share of a modest estate in costs. Given the weaknesses in the file — no independent legal advice, a documented capacity concern, and a pattern of isolation — we proposed resolving the dispute by treating the earlier, equal-split will as the one that should govern, rather than pressing for a finding of misconduct against Fiona personally.

The outcome

Their mother's estate, once the modest equity in her home and her savings were totalled, came to roughly $240,000. Under the new will, that entire amount would have gone to Fiona. Amrit and Raymond would have received nothing.

After reviewing the drafting lawyer's file and the medical evidence, Fiona's lawyer recommended settlement rather than a trial neither side could be confident of winning outright. The parties agreed to administer the estate as though the earlier will controlled, splitting the roughly $240,000 estate three ways after estate administration costs, at approximately $75,000 to $80,000 per sibling depending on final expenses. Fiona kept a small personal item their mother had specifically promised her years earlier, which had never been in dispute.

The settlement also avoided a public trial that would have required all three siblings to give evidence about their mother's final months and about each other — a process that tends to do lasting damage to family relationships even when the legal outcome is favourable. Amrit and Raymond got the outcome they had come in seeking: an estate divided the way their mother's long-standing will had always said it should be, without a court needing to formally brand the new will invalid.

The case settled roughly eight months after the notice of objection was filed, well short of the year-or-more timeline a contested trial would likely have required. It resolved because the evidence was gathered early and organized clearly enough that Fiona's own lawyer could see the difficulty of defending the new will at trial.
