What is my obligation in the state of Missouri to pay for college if I move the order to the state of Missour?

I am cuurently paying child support on an order in the state of Indiana for the past sixteen years. I have been a resident of the state of Missouri for the last twelve years and the woman who has custody of our child has been a resident of the state of Florida for at least the last ten years.
My question is regarding my obligation pertaining to payment of college tuition. I believe that the law in regards to support in the state of Florida does not obligate me to pay for college as it does in Indiana and I would like to know the law in the state of Missouri. My question is "if based on my residency in the state of Missouri if I amend the Indiana court order and move it to Missouri based on child support law in Missouri will I be obligated for college tuition?"
