Hey can someone please help me help my dad?

long story short my mom cheats\ed on my dad took his money, and basicly neglected me and my dad. her mom,my grandma is a lawyer so basicly went against us. i live with her(my dad bought the house but its under my moms name:/) anywho. I want a bank account i almost got one with my mom but she did something bad so i dont trust her... Shes making my dad pay child suppport(she used to get money from him for it but she'd pay her debts get her nails and kind of ignore my needs) and now i want a bank account but on my dads and i want to know if a portion(because i understand its also for bills) of childsupport can be transferred to my account underhim seeing that im 16... I'm responsible and i go to the best school in my state so is this possible?
