we have for some time had LPA of mums affairs and health care needs, we have found we have come up against some companys who wnat evidence of the fact mum lacks mental capacity, which we are in process with at the doctors. what happens during a session to determine lack of mental capacity, im really not keen on putting mum through any more stress, doing the mini mental test at hospital was bad enough she couldnt do it at all. why do these comapnys want this, when LPA is in place and we handle her affairs. even our solictor has been onto them and asked and said we dont need mental capicity being evident as LPA registered with public guardianship is enough to warrent the power to act on her behalf. can someone please explain.
