No. There is no fixed age in New Jersey when support stops. Once your child turns 18 and/or becomes financially independent, either you or the other parent must file papers with the court asking that the order be terminated or adjusted. Based on the facts, the court will decide if the child still needs a support from the parents. This is known as emancipation. Generally, the court presumes that children under 18 need support from their parents. In some cases, support may continue through college or longer. Support may terminate automatically if your current order specifies a date, age or circumstance when support stops.
