<prompt> Human: This is my first post. I know nothing about finance or the legalities of home owning. Please let me know what other info I should provide so that my question can be better answered. This is actually happening to my boyfriends mother but I will post from his perspective for the sake of convenience.15 years ago my mom, my two brothers and myself moved into a 4 bedroom home with my aunt and uncle and my three cousins. My mom, aunt and uncle went in together on the down payment. My aunt and uncle paid a larger portion, my mom paid about half of what they did and the rest was paid for with money gifted to them by their sister. From that point on my mom split the mortgage payments with my aunt and uncle 5050 despite the fact that my mom was a single mother supporting three kids. Although, I believe my aunt and uncles are the only names on the deed, they had a long standing agreement that they owned the house together. My uncle passed away this August and my brother and I moved back in a few months before to help out my eldest brother has lived in the house for the last 5 years after an accident immobilized him. My three cousins all have families of their own now and live elsewhere. My two brothers and I both help my mom make her half of the payments and my eldest brother pays all utilities and bills for the entire house. Since my uncle passed away my aunt has tried to make changes to the agreement. She now claims that they never agreed to won the house between the three of them and that any payments my mom made were rent paid to her- the landlord. She claims that because my mom paid less for the down payment it is irrelevant what she payed but they wouldnt have been able to buy the house if my mom hadnt contributed all her life savings up to that point!. She has demanded that my brothers and I begin paying our rent to her so that it will no longer go towards my moms payments. She has insisted that my mom begin paying more of the mortgage even though she is already paying half. My uncle was always fair and made sure to show my mom the statements every month so that she could see that payments were being divided equally in half. Now my aunt refuses to let my mom see any statements or paperwork on the house. She has become increasingly volatile and often yells at my mom and accuses her, my brothers, and I of stealing her jewelry, clothes, toilet paper, potatoes and anything else that pops into her head. She has spoken with my cousins who no longer live in our home and told them that we are stealing as well. Our cousins are all in agreement that my brothers and I need to pay rent to my aunt because we are living at home after college although, when the three of them moved back in for years after college, and brought friends to live there as well, they did not pay a dime and neither did their friends. My aunt has declared that if we dont do as she demands then she will sell the house and my mom wont see a dime. My mom has been putting all her money into this house for the last 15 years, working 2-3 jobs and raising three boys, because she believed this is where she would retire with her sister, brother-in-law, and children. What options does she have? How can she remain living in the house without aquiescing to my aunts demands?  <response>: I believe my aunt and uncles are the only names on the deedThis is probably not going to end well for your mom.
