Child received trust we are the great grand parents and need to ask for monthly payments to support him until age 18 he is now 9 we have had them for

You need to find out who the trustee is.  If there is no private trustee, then possibly the money is being held in the TRust department of the County Court.  If the child received the trust as the result of the death of a family member or from a personal injury suit, then the money could be held in the Court's Trust - Minor's Trust.  Call the County Court of the county in which the matter took place and if they are holding the money they can tell you the procedure you would use to access the money.  Good luck !
