My children were left a substantial amount of money by their great grandmother, that was to be held in a trust till they each turned 18. Their step grandmother was made trusted of the account. She refused to release my older daughters money when she turned 18, saying it was invested and needed to finish the term before it could be released. My daughter has since passed away and she refuses to release the money to myself or to be put in trust for my grand son. She has paid out a percentage to my second daughter, but has not given any paperwork, will not show me the will or any details of what she has been doing with the money for 9 years. What do I do.
