My mother was hospitalised yesterday, and a few things came to light. She has a carer, who my sister and myself are thinking may be pilfering her superannuation. It was revealed yesterday that my mother has given her access to her pin numbers and key card. We believe that our mother is possibly in early stages of dementia, although this has not been diagnosed. We spoke last night and feel that it may be time for us to step in and request control of her finances, so that she has enough money to live through her retirement. My questions are, what rights under family law do we have as her children to make this happen? Although she appears to be cognitively functioning is there a way for us to somehow assume the power to ensure that she will not get cleaned out completely? Thanking you in advance.
