An elder relative, over 100 years old but with their mental faculties remarkably intact, has informed me after the death of their eldest child that I will be the executor of their estate. Let's say the estate's total value is more than $1 million and less than $6 million. It will be divided among ten beneficiaries, each receiving a percentage.
One heir currently lives in a house that would be part of the estate. The elder relative has stated that they must keep the house, anything inside it, and perhaps some additional funds for property taxes and such "off the top" (meaning, they receive this in addition to their percentage of the remainder).
For reasons that stretch over decades of family history, I believe strongly in the justice of this arrangement (which I do not benefit from). The beneficiary in the house devoted considerable time and energy to caring for the testator. Other beneficiaries have their own opinions, but most at least accept it as their relative's wishes.
Unfortunately, this arrangement is not reflected in the will. While I have expressed that I think this plan needs to be specified in the will, I doubt that will happen. In our culture, it is not well received to tell an older family member they must do something. The testator is the unquestioned benevolent head of the family.
What can I do, now and/or after the testator is deceased, to make their wishes occur? I'm guessing that if beneficiaries decide they want to fight about this, then there isn't much that can be done, but are there elegant solutions available if the other beneficiaries are cooperative?
