quitclaim

Hi my husbands dad has been a alcoholic his while life, his girlfriend from a year passed away and he started a binge and stopped eating. He came to us and asked us to move Ob with him and help him. We lived 4 hours away from him and I have a 2 year old and a 7 month old at the time. Another reason we were asked to move is because he told us he was going to jail. So since we wanted to save my father in laws life we gave up our rental quit are jobs put our life in storage and moved. We all sat down and made an agreement that we he was putting the house in my husbands name because he can't take care of it meaning bills and taxes etc. So we all agreed that we were selling the house and moving back home and we would buy either 2 properties or one with a guest house. He also gave me and my kids a 2001 gmc Yukon ...so I sold my old car and paid the back taxes and bought new tires for it. I have 4 witnesses that he has spoken to about all the good he has done for my husband and I for giving us the house and cars. Now he's mad because we won't let him drive the Yukon, momd you he has no drivers license and hasn't had one In 20 years because he has had 9 dui so now he called a lawyer and thinks its just that easy to call a lawyer and out everything back in his name ??; yes he was drunk but he's been drunk for 50 years, and I have witnesses for when he was 100% sober he said the same thing . He just expects us to move out ?? What do we do ..everything was signed and notarized in his presence he even have.my husband power of attorney ....he can't process anything was forced ...it wa his idea
