Went to see him last night and 2 cops escorted me out? My father has a lawyer now just waiting on the lawyer to make the move so my dad can change his DPOA to me and my other sister.... very sad, he doesn't deserve this and the Dr and the Social worker seems to be budding with my oldest sister..... my father has rights
#2 - A DPOA holder can not restrict who sees who. Those powers are not part of a POA.
#3 - This is VERY IMPORTANT to know - A new POA document does not replace an old POA. The current POA holder (your sister) has to formally resign the position. There is a legal form for it that an attorney will draw up and file with the county clerk. A desire to change POAs by your dad means nothing unless the legal process is followed. The new POA document won't be legitimate or in effect even if it is complete and notarized and paid for.
I know this for a fact and personally because I went through a truckload of effort to get a POA established for my mom in her home state, not knowing she had already done that years ago & never told me. I went to use my POA and found out that the one on file with the county clerk superseded the new one I had done. My uncle & cousin would have had to do the formal resignation process to get out of it. We did not pursue any farther.
#4 - Now what stands up in court may not be what stands up at the living center front desk. If sister has posted a "do not allow in" notice, the facility may just be following instructions. And they are not going to get in the middle of a dispute between siblings or interpreting the law. If you have specific concerns, you can talk to the resident manager about what their policy & procedures are on that kind of thing.
