She is competent. They have no legal rights except for just became health care surrogate shared with my “good” sister. I’m a RN and fully capable of taking my mom to live with me. If she wants to come live with me, can they do anything? Currently she is in a rehab but doing well. My sister doesn’t want her anymore. She has lived with them for the last 8 years but she wants to remain in control. What can we do?
