In order to properly answer your question, I would have to see the Judgment of Divorce, signed by the court. You say you do not have a “support agreement” but rather a “mutual agreement” between you and your ex. I would have to see that agreement to review, whether in fact, it discusses the issue of child support. Generally, the child becomes emancipated at 18 years old if he or she does not continue on to higher education, especially if the child is working full time.
Therefore, in the absence of any agreement to the contrary, I believe you would not be responsible for child support any longer. In order to be sure, however, as I said, it is important to review the official documents relevant to this question.
If you are living in the New York City metropolitan area, please call me for an appointment at 212-370-1660 to arrange for a meeting to review the documents.
