“Generally, child support is money that you can use to help pay for your child’s basic needs such as education, food, and shelter. In Texas, the law does not define what child support needs to be used for, so you can generally put the money toward whatever seems appropriate.
If your teen will need a car to drive to school and/or work seems like an appropriate use. Since Texas doesn’t restrict the use of child support, you should legally be able to use this money to buy a car.
If you’re financing a vehicle, you may need to provide the lender proof of income, which can include the child support you receive. Don’t be surprised if they ask for this. You aren’t required to provide this, but it can help show financially stability and improve your chances for loan approval. If you’re buying a used car with cash, this won’t be an issue.
