I am a joint executor of my Aunt's will with my cousin. My Aunt died recently and has left her estate to her nieces and nephews in a will she took out in December 2013. She has 2 children however, who were made wards of the state in the 1950s. I dont know if they were adopted. She has never wanted to acknowledge them or contact them. I wonder if they can claim a share or all of the estate and could go about contesting a will? Her estate is less than $200k.
