Conn. Practice Book § 25a-8 — Order of Notice

(a) On a petition for support or the establishment of parentage when the adverse party resides out of or is absent from the state or the whereabouts of the adverse party are unknown to the plaintiff or the applicant, any judicial authority or clerk of the court may make such order of notice as he or she deems reasonable. If such notice is by publication, it shall not include the automatic orders set forth in Section 25a-7, but shall, instead, include a statement that automatic orders have issued in the case pursuant to Section 25a- 7 and that such orders are set forth in the application or petition on file with the court. Such notice having been given and proved, the judicial authority may hear the application or petition if it finds that the adverse party has actually received notice that the application or petition is pending. If actual notice is not proved, the judicial authority in its discretion may hear the case or continue it for compliance with such further order of notice as it may direct.

(b) With regard to any motion for modification or for contempt or any other motion requiring an order of notice, where the adverse party resides out of or is absent from the state, any judicial authority or clerk of the court may make such order of notice as he or she deems reasonable. Such notice having been given and proved, the court may hear the motion if it finds that the adverse party has actually received notice that the motion is pending.
