In a will contest, which factor is least relevant in proving undue influence by a caregiver who stands to benefit?

• A. X spent a lot of time alone with T in the months before signing her will.
• B. T's prior will would have given all of her property to her niece.
• C. T was in a mentally weakened state when she signed.
• D. T drove a $100,000 automobile.

Answer: (D)

Undue influence in a will contest is shown when a caregiver with a financial stake in the outcome uses their relationship to shape the testator’s decisions, focusing on opportunity to influence, the testator’s vulnerability, and the caregiver’s motive plus evidence that the will reflects that manipulation (such as a change from a prior plan).

Spending a lot of time alone with the testator before signing creates opportunity for influence, since isolation can make it easier for someone to press their views. A prior will that would have given everything to a different beneficiary suggests a motive or at least a significant change in the testator’s wishes that could have been driven by the caregiver’s influence. The testator being in a mentally weakened state signals susceptibility—when someone is less able to resist pressure, influence is more likely to be effective.

Drove a luxury automobile, by contrast, doesn’t reveal anything about manipulation, vulnerability, or the testator’s free will being overridden. It’s an unrelated fact about wealth or lifestyle and doesn’t indicate the caregiver exerting control over the will. Therefore, that factor is the least relevant to proving undue influence.
