<human>: My SO is currently enrolled in college in Missouri, and is receiving child support from her father, because her mother is still supposedly supporting her and therefore she still needs the money. That money had been used for car payments while in high school, but now in college she recently purchased a new car. 

Now, the ONLY way she can pay for this car was through the child support money that he dad is sending, she works part time and is not getting any help for classes, so the car payment is not possible without it when rent and all other expenses is taken into account. However, her mom is terrible with money. She already flaked out on the first payment, which my SO thinks she can cover for now, but she can not keep up paying for these payments.

Other than trying to set up an automatic transfer from the bank account of her mother to give her the money, we can not figure out a way for her to get it before she blows through the money in the bank account.

I know I can not provide a ton of answers since I am not her, but we just wanted to know if there was a way she can take herself out of the child support? She looked into getting it given to her directly instead of her mom, but she said there was issues surrounding them expecting her mom to be supporting her so they won't send it to her. We do know that her Dad will probably just give her the money without the government being involved if she can take herself off of it or opt out or something like that, and thereby avoid having to wrestle it out of her mothers finances. Is there any system in place to opt out of child support, especially since she isn't getting or seeing any benefit of it anyway?

Could you distill the essence of the text into 1-3 sentences?
<bot>: SO's mother is bad at finances and loses child support money too fast, can my SO opt out of child support or get it herself in any way?
