My sibling (mother’s openly admitted favourite child) moved into her retirement village unit as her carer, gained power of attorney (we can’t find out what kind) and within 18 months, 93 year old mother has been placed in a nursing home. We had not been permitted access to our mother since sibling moved in, being told that mother stated she does not wish communication with us. Sibling will not allow us to know where mother is living, her health status, etc. Sibling has stated that mother is of unsound mind. We need to know how to gain access to our mother. A police welfare check was requested but was done by phone and still yielded no result. We are unconcerned about her estate as we realise sibling will either inherit or use POA to sell or claim ownership. We need to know if mother has just been dumped for financial reasons and if she ok.
