The court may instate a modified child support order. Yet, the other parent may refuse to abide by these payments, offering less than you need or failing to make payments altogether. If this happens, they could face penalties from the state. The courts may impose fines and even jail time if the other parent refuses to comply. It could also find the other parent in contempt, leading to other complications. You Have Legal Options When you need to change your child support agreement because your circumstances change, you could contact an attorney about how to navigate this process. Your lawyer can explain your options and handle the paperwork for you. You do not have to handle this process on your own or without an advocate.
