I do not have POA or gaurdianship, we are working on that, and she hasn't been diagnosed for her memory problems. What can we do to stop other siblings for borrowing money, or having her cosign for loans? Is there any thing we can do about the current auto cosighing she did for my sister? My mom is now getting letters from various banks that her request for the auto loan has been denied, and I am worried about her credit.
See what they say
I got a recommended attorney from a friend, and for short 15-30 min discussions about topics , the attorney did not charge me for the initial advice. This could vary depending on the attorney of course. He said he would start charging if we wanted to file something official in court.
Start with APS and ask for guidance or attend an attorney and request guidance.
Charges should be pressed and her name removed.
Odds are that the banks are saying no because of her age.
