Power of attorney resposibilities
I have POA for my mentally challenged mother, prior to getting this POA she made some decisions which removed her medical insurance coverage. She then got sick, had to be hospitalized and needed the coverage so not having it has incurred some bills. With me now having POA can I be held responsible for her medical bills?

Purchase Agreement
I signed a purchase agreement on a mobile home. Husband did not. It has both names on the form to be signed by plus I initialed where it has earnest money on it. We put down $15,000.00. Have I messed up. We live in Va. but the trailer we want to buy is in tennessee. We found out after the fact that there will probably be extra costs that were listed on back of form I did not see. What can I do to rectify this situation.
