My uncle - my auntie's brother - has died. She has been named as executer and is selling his properties. She also had power of attorney before he died. I am now worried that she is abusing the trust that has been placed with her as: a collection (worth quite a bit of money) was, according to my aunt, given away rather than sold, his car (worth £55k) is now sitting with a DLA badge for executrix outside her house. House and other property has also seemingly been put on the market but I can find no trace anywhere. He also gave her £100,000 before he died which has mysteriously disappeared. My uncle left everything to my auntie on the understanding that everyone else in the family was 'taken care off'. She is now saying that he only left everything to her. I am very concerned that my aunt is administering the estate for her own gain and need advice on how to proceed. My uncle was survived by his mother, brother and aunt.
