What are Options If Grandparent Changes Will?
Estimates of $124 trillion in wealth expected to be transferred to younger generations have left many young adults expecting to receive generous inheritances. One survey said most Americans expect to inherit around $334,000 from their parents. But a recent article from yahoo! finance presents the following scenario: “I’m 43 and was set to inherit $400,000 –until my dad had my grandma change her will. Can I demand she change it back?”
What options does this 43-year-old have?
He can speak with his grandmother. However, he needs to be very careful about his conversation. He must also realize he might not get the answer he wants. Demanding that she change her will is a hard no. Ultimately, it’s up to her. He would also be doing the exact same thing his father did: telling the grandmother what she should do.
The smartest thing may be to encourage the grandmother to meet with her own estate planning attorney, alone, with no family members present. An experienced estate planning attorney will assess her mental capacity and may even bring in a gerontologist or social worker to confirm her mental capacity.
The attorney may ask the grandmother why she changed the will and document the conversation. If she genuinely wants the father to inherit, the memo will document her wishes. If she was coerced into making the change, a seasoned estate planning attorney will usually pick up on it.
Her wishes and the will may not change. However, it will give the grandmother a chance to make her own choice without pressure from the father or the grandchild.
Understanding why the change was made is important. A competent adult is allowed to change their will anytime they want, even if it makes prospective heirs unhappy.
If she was pressured or unduly influenced, or if she didn’t have the mental capacity to understand what she was doing, then the jilted heir should have a conversation with an attorney.
Were there any changes in behavior indicating that something malicious was going on? If she appears confused, fearful, isolated, or unable to explain the changes in her own words, the issue becomes less about protecting an inheritance than about protecting her from exploitation.
The grandson may have more luck acting after the grandmother passes. If the change was the product of undue influence, the will can be contested in court with a claim of undue influence or duress. These types of cases typically hinge upon fact patterns, including details like who drove her to the lawyer’s office, how dependent she was on the individual and who was in the room when the will was changed.
However, this is not an easy situation. If the will has a no-contest clause, litigation could result in no inheritance at all. If litigation goes forward, legal costs could take a big bite out of the inheritance. This is why an independent visit to an attorney might be the best way forward.
