The situation
Before Rosa ever spoke to us, she had already tried the thing most caregivers try first: keeping careful, informal track of things herself. For nearly three years, Rosa had been the person who showed up for Megan almost daily, an optometrist in her seventies whose memory had begun slipping in a way that was not steady or predictable but came and went, sharp and lucid for stretches of weeks, then fogged and confused for days at a time. Rosa kept a private notebook of her own, dates and observations jotted down after visits, mostly so she could track patterns for Megan's doctor. It was thorough in its way, and it was also entirely useless for the purpose it eventually needed to serve, because it had never been written with a legal challenge in mind, and it showed.
Megan had no children of her own. Her closest living relative was a nephew, Tyler, a police sergeant who visited occasionally but had not been part of Megan's daily life in the way Rosa had. When Megan decided, during one of her clearer stretches, that she wanted to update her will to leave a meaningful portion of her estate, worth somewhere between one point two and two and a half million dollars once her home, investments, and a small optometry practice she still partly owned were accounted for, to Rosa in recognition of years of unpaid care, she asked Rosa to help her find a lawyer to do it properly.
This is where Rosa's own instinct, and her private notebook, had already tried and failed to solve the underlying problem. Rosa knew, from watching Megan's condition for years, that a will signed on the wrong day, one of the foggy ones, would be vulnerable to exactly the kind of challenge Tyler was likely to bring given how surprised and unhappy he was expected to be. Rosa's notes tracked Megan's general pattern over time, but they said nothing specific about Megan's state of mind on any particular day a legal document might be signed, and a family member's private journal, however sincere, was never going to carry weight against a formal challenge the way something prepared at the time, by someone with no personal stake in the outcome, would.
By the time Rosa brought Megan to us, both of them understood the will needed to be handled carefully, but neither of them yet understood how carefully, or what kind of documentation would actually matter later if Tyler decided to fight it.
Why this was harder than it looked
Fluctuating capacity is one of the more difficult situations a wills lawyer handles, precisely because the legal question is not whether someone has capacity in general but whether they had it at the specific moment they signed. Megan's good days were genuinely good; on them, she could discuss her finances, her practice, and her wishes with total clarity. Her difficult days were genuinely difficult, and on those, the same conversation would have produced a document that could not withstand scrutiny. The law does not average these out. A will signed during a lucid interval can be entirely valid even if the same person would fail a capacity assessment the following week, but proving which kind of day it was, months or years after the fact, is where these cases are won or lost.
The deeper problem, and the one Rosa had not fully appreciated before coming to us, was that the practical fix, timing the signing for one of Megan's clear stretches, was not itself a legal solution. Anyone could time a signing well and still face a challenge later, because a challenger does not need to prove the day was actually bad, only that it is plausible enough to put the will's validity in real doubt. What protects a will signed during fluctuating capacity is not the good timing itself but the contemporaneous record proving that timing was real: notes taken by someone independent, at the time, describing specifically what was observed, not a general impression formed after the fact.
Tyler's eventual challenge, when it came roughly a year after Megan's death, argued exactly what we had anticipated: that Megan's memory issues were well known within the family, that a will leaving a substantial share to a caregiver outside the family was inherently suspicious, and that no one could say with confidence Megan understood what she was signing that day. It was not a frivolous argument. Undue influence and incapacity challenges involving caregivers are taken seriously precisely because the pattern, a vulnerable person, a paid or unpaid caregiver, a will that departs from what a family member expected, is a real one, and the law is right to scrutinize it closely rather than assume good faith.
Rosa's earlier instinct, to keep her own private notes tracking Megan's condition, had actually made this harder rather than easier in one specific way: a caregiver's personal journal, describing the person she cared for as declining and unpredictable, could just as easily have been used by Tyler to support the challenge as to defend against it. It showed a pattern of concern that, taken alone and out of context, painted exactly the picture of vulnerability an undue influence argument needs. Part of what we had to do, once litigation began, was make sure Rosa's own notebook was understood in its proper context, a caregiver's honest record of ordinary ups and downs, rather than evidence that Megan lacked the capacity to make decisions at all.
What we did
- Arranged the signing for a documented period of clarity, working with Megan's family doctor to identify, based on her recent pattern, a window likely to be a good stretch, though we were careful to explain to Rosa and to Megan herself that timing alone would never be enough on its own to withstand a challenge if one came later.
- Conducted a private capacity assessment immediately before signing, arranging for a physician independent of the family, someone with no relationship to Rosa or any financial stake in the outcome, to meet with Megan on the day itself and record, in writing, specific observations about her understanding of her assets, her intended beneficiaries, and the nature of the document she was about to sign.
- Took our own contemporaneous notes during the drafting meetings, documenting Megan's own words where possible, her reasoning for including Rosa, her understanding of what excluding Tyler as a primary beneficiary meant, and her ability to explain her decisions in her own terms rather than simply agreeing with suggestions put to her by us or by anyone else in the room.
- Met with Megan without Rosa present for key portions of the process, a deliberate step to establish that Megan's wishes were her own and not shaped by Rosa's presence in the room, which mattered enormously once the eventual challenge raised undue influence as its central concern rather than capacity alone.
- Documented Megan's reasoning for the specific bequest, capturing in writing why she wanted to recognize years of unpaid caregiving specifically, including details about what that caregiving had actually involved, rather than leaving a vague impression that Rosa had simply been favoured, which gave the eventual defence a substantive story to tell rather than just a procedural one.
- Preserved the physician's notes and our own file as a coordinated record, making sure the two independent sources, the doctor's clinical observations and our own drafting notes, corroborated each other on the key point: that this was one of Megan's clear days, that she understood what she was doing, and that her reasoning was consistent across both meetings.
- Advised Rosa on keeping her own conduct above reproach for the remainder of Megan's life, since a caregiver who appears to isolate a testator from other family members after a will is signed can undo much of the good a well-documented signing accomplishes, and Rosa's continued openness with Tyler mattered later.
- Prepared Rosa for what a challenge would look like, being honest with her well before Megan's death that a will favouring a caregiver over a family member draws scrutiny almost by default, and that the documentation being built was there to answer that scrutiny, not to prevent the challenge from ever being raised at all.
The outcome
Tyler's challenge did not succeed in overturning the will outright, largely because the contemporaneous notes, both the independent physician's assessment and our own drafting record, gave a consistent, specific account of Megan's condition on the day she signed, something Rosa's earlier private notebook could never have provided on its own. But the challenge was not without cost. Litigation over a will's validity is expensive for an estate to defend, drawing down funds that would otherwise pass to the beneficiaries, and rather than fight the matter through to a full hearing many months away, Rosa and the estate agreed to a negotiated settlement that reduced her share by a meaningful amount to bring the dispute to a close before legal costs eroded it further.
Rosa was clear with us, afterward, that she considered this a loss contained rather than a case won. She kept the bulk of what Megan had intended for her, but not all of it, and she spent a difficult year knowing her relationship with Megan, and Megan's own wishes, were being publicly questioned by someone Megan had trusted as family. The documentation did what it was supposed to do: it made the challenge losable for Tyler rather than a foregone conclusion, and it likely pushed him toward a settlement he might not otherwise have accepted, but it did not make the challenge free, either in legal cost or in the toll a year of dispute took on Rosa personally.
What stayed with Rosa afterward was less the settlement amount than the realization that the notebook she had kept out of love and habit for three years had never been the thing protecting her. The independent, contemporaneous record built at the moment of signing was what mattered, and it existed only because she and Megan had gotten legal help before signing, not after a challenge had already begun. She has said since that she wishes she had understood, years earlier, that watching Megan carefully was not the same as documenting her carefully, and that the difference between the two turned out to matter more than almost anything else in the case.
What you can learn from this
- A will signed during a lucid interval can be fully valid even if the same person struggles on other days, but only if there is a contemporaneous, independent record proving which kind of day it was.
- A caregiver's own informal notes, however sincere, rarely carry the same weight as an independent physician's assessment taken at the time of signing.
- Meeting the testator alone, without the intended beneficiary present, is a simple step that directly answers an undue influence concern before it is ever raised.
- A will that favours a caregiver over family draws scrutiny by default. Assume a challenge is possible and document accordingly, even when the relationship feels beyond question.
- Defending a will successfully does not always mean the outcome is unchanged. Settling to limit further cost and exposure can be the right call even when the underlying document holds up.
