Rule 16.Continuing jurisdiction

Rule 16 is a single sentence that fixes when the court's grip on a case begins.

The provision

The family court has jurisdiction of the parties and control of all subsequent proceedings from the time of service of the summons and complaint.

Two separate things

Jurisdiction of the parties is personal jurisdiction — the authority to bind the people before it. Control of all subsequent proceedings is broader and is the more useful half: it means the case, once begun, belongs to the family court, and later steps in it are that court's to manage.

The trigger is service, not filing

The clock starts at service. Filing alone does not do it. That ordering runs through the ruleset: Rule 6(c) will not let a matter be heard until the action is entered in the file book and the pleadings are filed; Rule 20(b) measures the financial declaration deadline from 45 days after the complaint is served; and Rule 17(a) is about a defendant who has been served and has not answered.

Why "continuing" jurisdiction

The title names the shape of family court work. A decree is rarely the end — custody, visitation and support come back for modification and enforcement for years. Rule 16 states that the same court retains the parties and the proceedings throughout, which is what makes Rule 14's rule to show cause, Rule 24's automatic support enforcement and Rule 27's visitation enforcement work as steps in the existing case rather than as new lawsuits.
