My father has recently become a triplegic due to an illness he's had 40 years. My brother and I are being told his girlfriend has poa which is fine except for the fact it appears she and family are not letting us in loop. We feel they have a paranoia we may put him in a home which is simply not the case. We simply want and feel we have the right to know. Now we r being told by girlfriend not to ever call and she would call police if I show. Father is on heavy meds and we have good relationship with him. My brother, myself, and my child r most immediate. Don't we have presidence over other family? And do I have the right to demand proof of poa?
