hello I am a resident of CT I am looking for some legal advice on denying my share in a will.

I took care of my aunt who was ill, during the time I was living in her home with my husband & kids, her son had her change her will to leave me half of her home (leaving him the other half) i was kicked out of the home a year after her death. Her son stated we were selling the home to pay for her debt. Now, I am out of the home the house has not been sold and I am not allowed to go back to the home according to him and he is demanding I pay $15,000 of her debt. I never wanted the home and asked that I was not included in the will. While I lived there after my aunts death I paid $6,000 on her back taxes just to find out I was being kicked out within 2 months of paying the back taxes on the home. I would like to be removed from the will. I should also add that the will is not accurate it has me listed as my aunts daughter although she took me in as a child and raised me i was never adopted. Also it has me as Amanda Chartier and I never changed my last name when I was married.
