My husband is FPOA and trustee for his mother, who lives in another state, and handles all finances. Since his sister lives near their mother, she was named as HCPOA with agreement of all family several years ago. Recently, SIL has taken on more of a role in managing MIL's care, which should be minimal since MIL lives in a CBRF/AL; changing doctors, refusing certain medications, in opposition to MIL's requests. We suspect the psych evaluation was requested to settle the question of competency in face of differing decisions by SIL and MIL. We have asked to see the psych eval report, but SIL refuses, claiming HIPAA rules (although my husband is named later on the HCPOA). MIL has not been diagnosed with Alzheimer or other dementia, she is just cranky and outspoken, and makes crazy comments, and inattentive if she doesn't like the subject of discussion. But she also has a lot of physical ailments that required the ALF.
It appears to other family members that SIL is enjoying being in charge, and is doing all this for her own reasons. Now her claims have put her own sensibility in question, and her demands (like whether other family and friends can visit) are causing dissension.
