Dear Eric: My mom died a couple years ago and my dad is still living. He has dementia and lives in a nursing home. I live in another state. Shortly before my mother’s death she told my sibling she could move into their house. My mom was also in a nursing home at the time. My sister has lived in the home since then. Shouldn’t she be paying at least some monthly rent into the estate? I feel that my brother and I are being taken advantage of. There was nothing in writing and my parents never gave her ownership.
