My aunt is in a nursing facility and my sister is POA (we are his only family left). She recently asked me to help sort out his finances because she has never been good at that and I work in the medical field and deal with insurance and Medicare/Medicaid. She signed a consent form with the facility. When I asked for his financial records they told me that the consent form was not valid and to call APS. When I spoke to APS they told me the POA had been revoked due to my sister exploiting my uncle. I do believe that has happened and would like to know if APS has the capacity to revoke a POA. A lawyer told me that they would have to go through specific legal channels. I would like to apply for guardianship, but the lawyer told me I needed to find out if APS revoked the POA legally.
