My father died about 2 years ago, his wife passed away about 6 months ago. Her daughter (no relation to my father) has taken control of the estate (not legally the executor). Her daughter has taken control of all of my fathers possessions and refuses to give any to my fathers children and her own siblings. There are possessions that he came into the marriage with, that were from his marriage with my mother. Is this legal?Is there anything that I can do?
