A relation got diagnosed with Alzheimer's disease. He was tested and deemed unable to even drive home from a test centre. Daughter then got him to do a power of attorney, then cleaned out his (substantial)account - she was supposed to set up a trust with other siblings. He died a few years later after which time the money which was meant to care for her mother (80's ) was kept by the daughter and drip fed to the elderly mother to the extent where mother was frozen with only an hours worth of heat even in the worst of the snow (she put a box on control to prevent access). The mother has now died and effectively cut said daughter out of will. Thing is on paper both mother and father died penniless. Meanwhile mean daughter sitting on funds in her own name. She refuses to give account of the monies to other siblings and is telling her mothers executives not to go to a solicitor/grant of representation/probate.
She is very intimidating. Elderly relative is executrix of mothers will and wants to back out due to this, thinks mean daughter is quite evil. Only other executor mentioned is v. weak and has always done whatever mean daughter told him (sadly including locking heat controls). What can 2 other siblings do - can one get made executor apply for grant of representation since others won't? Any suggestions appreciated.
