My father passed away 11 years ago. I have occupied the property since its original purchase. My father expressed to me that he was purchasing the house for me and my children so that we would have stability. My father and I looked at houses together and the house I now occupy is the one I chose. After my father's death, my brother took possession of the contents of my father's safety deposit box, his savings/checking account, and items my father owned. He has squandered the monies or no longer has the property. He now wants to claim an interest in the house that I have occupied for 19 years. The deed my father signed to give me ownership of the house was cancelled because the courts said the deed was executed improperly. The county is now propsing to increase my property taxes by $1100 per year. Can I claim adverse possession on the property? If so, what document or documents would I file with the court to do so?
