My grandmother (NY) owns a Co-Op that she purchased over 30 years ago. She wants to leave it for me, my mother, and my aunt for when she passes away. We want to sell the co-op apartment and split the money from the sale three ways when she passes. What is the best way to do this? Do we need to make a trust, a gift or what? Will this affect her Medicaid or Medicare she is on? We want to get the legal documents and process done ASAP. Please advise!
