Rule 1:12.Service of Papers after the Initial Process.

Rule 1:12 governs how papers get served once a case is already underway — after the initial process that starts the case. Every pleading, motion, or other paper filed after that point, along with requests for subpoenas duces tecum, must be served on each counsel of record on or before the day of filing. The rule lists the permitted methods: hand delivery, dispatch by a commercial same-day or next-day delivery service, fax, email (when Rule 1:17 authorizes it or the recipient has consented in writing), or mail.

Service takes effect, subject to Rule 1:17, at the moment of delivery, dispatch, transmission, or mailing. Email service is the exception: it is not effective if the party making service learns that the attempted service never reached the intended recipient.

The rule also requires proof. At the foot of the pleading or request, counsel must append either an acceptance of service or a certificate stating that copies were served as the rule requires, showing the date and method of service. If service was made by email, that certificate must also be served — by mail or fax — on each counsel of record by the day of service.
