Hi, me and my sister are going through a situation at the moment where our other sister is accusingbus of syraling from our father, she has raised an issue with the opg, and we have been told today from social services safeguarding team that she has managed to get my dad to sign a form revoking me and my sister as lpa's, she says he hasn't got capacity to look after his own money, surely this means he hasn't got capacity to sign a legal document, is this illegal or just wrong, thanks in advance for any advice, it is greatly appreciated.
