my mother died an had no will. she had requested that all her belongings be divided equally between the children. my brother got her house, but doesn't want to divid the contents. the house is all he was to get and contents be divided. he has already gotten rid of her car and some personal belongings that were to be divided. brother an his wife keep saying that he has power of attorney, but won't produce a document showing it. she had alot of old antique items. sister in law is starting to sell them. i would like to have some of them for sentimental reasons, but i cannot get to them. also, my daughter had bought some items and let my mother use them, and she can't even get those items back. do i have any legal rights and what might they be?
