You can assert grounds for declaration of invalidity of marriage (annulment). In your case, the argument would be fraud that goes to the heart of the marriage. The argument would be that your spouse's promise to have children was central to the marriage. You will have to have your spouse served (in person or by publication) and you will generally have to have a hearing to establish your grounds for invalidity. You may want to retain an experienced family law attorney to assist you.
