My 90 yr. old mother is on the brink of needing assisted living (severe arthritis in knees and hips). My oldest sister lives with her and is her caregiver. The deed to my mom's house is still in my mom's name. She has willed the house to my oldest sister. Question: If Mom goes to an assisted living facility, what can/will happen to her house and my oldest sister's home there? There is a stipulation in my mom's will that upon her death, my oldest sister can stay for a certain amount of time in decedent's house. Thank you.
