Grandmother left me an inheritance that family "invested" for me. They tell me it is gone now. Part was a UTMA they withdrew which was sons college $.

There are many different ways these cases can go depending on who exactly took the money wrongfully.  The wrongdoer can be a trustee, an executor, a guardian, another family member, or even the bank. Statutes of limitation are different in every state and may be different depending on who took it.  Fraud is often a long statute of limitations but I would not hesitate in looking to hire an attorney.  I would probably start with a trust and estate attorney in your area.  They can likely focus the situation for you.  Good luck!  -John
