Dear Eric: When my mother passed away, her trust was split mostly between me and my sister, with a small percentage to my sister’s two kids. My mother and my sister lived together. My mother put the down payment on their house, and they split the mortgage and utilities. My sister covered most of the mortgage. I have always imagined gifting a percentage of my stake in the house to my sister because she has been responsible for providing care for our mother and shared the expenses.
