A Will Dispute Between Siblings, Settled at Mediation

The situation

Analyn, a long-haul truck driver, and her sister Zainab, a factory technician, were named co-executors of their father's estate after he died in Burlington following a short illness. He had spent his working life running a small supply business out of a rented unit before winding it down a decade earlier, and what he left behind was modest by design: the family home, worth roughly $260,000 in equity after the mortgage was paid off, and an RRSP worth about $40,000. Total estate value came to close to $300,000.

His will, updated about eighteen months before he died, split the estate unevenly. Analyn and Zainab were each left 45 percent. Their brother, Imran, a factory technician like Zainab, was left 10 percent — about $30,000. The will included a short note, in their father's own words, explaining that his son had already received significant financial help during his life and that this was accounted for in the final split.

Imran did not see it that way. He believed the will undervalued his relationship with their father and was signed at a point when their father was living with Analyn, in poor health, and increasingly dependent on her for day-to-day decisions. He filed a formal objection to the will being accepted for probate — the court process that confirms a will is valid and gives the executors legal authority to administer the estate — which meant Analyn and Zainab could not distribute a single dollar until the objection was resolved.

The three siblings had never been especially close as adults, but the estrangement deepened quickly once the objection was filed. Analyn, still driving long routes for work, found herself fielding calls from the estate lawyer between shifts, while Zainab tried to keep the house maintained and insured with no idea when — or whether — it could finally be sold. Neither wanted a prolonged fight, but neither felt they could simply hand over a share of the estate their father had specifically chosen not to give.

The legal problem

A challenge like Imran's puts the whole estate in limbo. In Ontario, a will only takes effect once it is proven valid — normally a formality, but once someone with a genuine interest in the estate raises a formal objection, the executors cannot simply proceed. The house could not be sold, the RRSP could not be cashed out and transferred, and legal costs on both sides would ultimately come out of the same $300,000 pool everyone was fighting over.

Imran's objection rested on two overlapping arguments. First, that their father lacked the mental capacity to properly understand and approve the changes to his will at the time he signed it, given his declining health. Second, that the uneven split was the product of undue influence — that Analyn, as the daughter he was living with, had improperly shaped her father's wishes rather than simply carrying them out. Neither claim is easy to prove, but neither is easy to dismiss out of hand either. Capacity and influence are assessed by looking at the full picture: medical records, the circumstances around when and how the will was signed, who was present, and whether the document reflected views the person had expressed consistently over time.

The strongest points in the sisters' favour were that their father's family doctor had seen him only weeks before the will was signed and recorded no concerns about his cognition, and that the lawyer who prepared the will had met with him alone, without either daughter present, and had made a note explaining his reasoning for the split. The weaker point was the note itself — it referenced financial help given to Imran years earlier, but no one could produce records showing exactly what that help amounted to, which left room for Imran to argue the stated reason didn't add up to the size of the gap.

What we did

1. Gathered the paper trail early. We requested the deceased's medical records covering the period around when the will was signed, along with the file from the lawyer who had prepared it, including any handwritten notes from that meeting. Contemporaneous records — made at the time, for a purpose unrelated to the later dispute — carry far more weight than anyone's memory of events years afterward.
2. Assessed the case honestly with our clients. We were direct with Analyn and Zainab that the capacity argument was weak on the evidence, but that the undue influence argument had real substance, largely because of the missing financial records behind their father's stated reasoning. Going to trial on that footing carried genuine risk, and a loss could mean the will being set aside entirely, which would send the estate into an even split none of the siblings had originally agreed to.
3. Recommended mediation rather than pushing to trial. In Ontario estate disputes, courts increasingly expect the parties to attempt mediation — a structured negotiation with a neutral third party — before a trial date is set, and Superior Court estate matters routinely take a year or more to reach trial once contested. We proposed mediation early, before legal costs on both sides climbed further and before positions hardened into something harder to walk back from.
4. Prepared a settlement range grounded in the actual risk. Rather than asking Analyn and Zainab to defend the will as written, we worked out what an equal split would look like against what the will actually provided, and used that gap to frame a realistic middle ground going into mediation — one that reflected genuine litigation risk rather than simply what felt fair.
5. Negotiated the split at the mediation session. Over several hours with a mediator experienced in estate disputes, the parties worked toward a compromise: Imran's share would increase from $30,000 to $65,000, funded by roughly $17,500 coming out of each sister's share. Analyn and Zainab's shares dropped from $135,000 each to about $117,500 each.

The outcome

The settlement was not a win for either side in the way a trial verdict would have been, and we told Analyn and Zainab that going in. Imran received roughly $35,000 more than the will provided, and the sisters gave up a combined $35,000 they were legally entitled to under their father's stated wishes. But it ended the standoff on terms both sides could live with, without the cost, delay and family fallout of a trial that could easily have taken another year and cost more, in legal fees alone, than the difference being fought over.

Once the settlement was signed, probate proceeded without further objection. The house was sold, the RRSP was collected, and the estate was distributed within a few months — the kind of straightforward administration that should have happened from the start, had the will's reasoning been better documented at the time it was made.

Analyn and Zainab also came away with something less measurable: the dispute was resolved privately, through a negotiated agreement, rather than through a public trial that would have required family members to testify against each other about their father's final months. For most families, that matters as much as the dollar figure.
