Can child support be continued after the child turned 18 if the divorce was granted in another state?

Thank you for your question.  Yes, depending on what the language in your divorce judgment or Marital Settlement Agreement states.  For example if the law in Georgia states that the child support automatically ends at 18 then you need to bring an application to the court to terminate child support in NJ. However, if there is a provision in your agreement discussing college contribution, the court would have to review the terms of the agreement. I recommend setting up a consultation with a matrimonial attorney to discuss your rights and obligations under the judgment of divorce and any marital settlement agreement that you may have entered into.
