Plain-English Summary
This is the rule that tells you which rulebook you are in. Part V governs family actions. It does not replace the rest of the Rules of Court, though — it sits on top of them.
Part I, the general rules, applies to every family action. Beyond that the rule splits by the kind of case. A civil family action — divorce, custody, support — also draws on Part IV, the civil practice rules. A criminal or quasi-criminal family action draws on Part III instead, and so does a juvenile delinquency action. In each case the background rules apply “insofar as applicable” and give way wherever Part V provides otherwise.
That layering matters in practice. When Part V is silent on something ordinary — how to amend a pleading, say — the answer is usually in Part IV, not in a gap.
Frequently Asked Questions
Do the regular civil rules apply in the Family Part?
Yes, for civil family actions. Rule 5:1-1 makes Part IV apply insofar as applicable, except where a Part V rule provides otherwise. So a Part IV rule fills the gap unless Part V has displaced it.
Which rules govern a juvenile delinquency case?
Part III, the criminal practice rules, insofar as applicable — together with Part I — except where Part V provides otherwise. Chapter IV of Part V carries the delinquency-specific rules.
What does “insofar as applicable” mean here?
It leaves room for a background rule that does not fit a family proceeding cleanly. The phrase signals that Parts I, III and IV are meant to supply ordinary procedure, not to be forced onto proceedings they were never written for.
