In estate planning, when a person signs a Living Trust or a Revocable Trust (they're the same thing), they are identified using one of several different terms. These include "Settlor", "Grantor", or "Trustor." In Trust lingo, they all mean the same thing and they refer to the person establishing the Trust.
Sadly, as an estate attorney I often see families where a person is in their final days before death and the squabbling has already begun. Often these are families where no one expected there to be bickering over the dying person's estate--and yet it happens all too often. The fact is, sometimes money changes people.This underscores the importance of thorough estate planning.
