oklahoma. I live in oklahoma and my mother is dying of cancer. I called my sister that my mother has only spoken with 3 times in 10 years. My sister is now trying to access my moms banking info and she made a copy of my mom's credit cards. I let her get a poa (mom is still comp) and it will never be able to be used. my mom also did a will. My sister is acting very suspicious. Is there anyway she could access my mom's accounts? If so, what can I do to protect my mom and myself? My mom is leaving us with 5050 split.
