My brother died several years ago and left his estate to my nephews. Situations keep arising where assets in the estate remain but wern't included in the will. Organizations locate me as the nearest living relative. In some cases I have received proceeds ( a life insurance policy) even though I told the organiztion that I wasn't in the will. Another situation has arisen and I notified my nephews. My children feel that I may be inconsiderate of their interests. Are there laws related to my situation?
