5 years ago I bought a home with my mom. She only lived in it for 1 year then my sister put her in an assisted living facility. My sister has power of attorney and is on all her financial accounts. My sister has helped herself to some of my mom's money. Now my mom is out of money. First I offered to buy my mom out. Everyone agreed on the amount-then my sister changed her mind. Now I plan on getting married and offered to sell the home. My sister got mad because I shared some nasty emails she sent to me. Now she says I need to deal with mom and she is dropping her off next month to live with me -since it is her home. I work full time and I have a roommate. What rights do I have?
