New Jersey discovery deadlines: 60 days for interrogatories, and you cannot agree to more

New Jersey's discovery clocks are unlike anyone else's. Interrogatories carry 60 days, the longest period in the country. Document requests carry 35. Requests for admission carry 30.

Three different numbers, and the generous one comes with a catch: you and your opponent are not allowed to agree to extend it.

The three deadlines

Carrying one number across to another device is the most common way to miss a New Jersey discovery deadline. The interrogatory period is nearly twice the admission period.

Interrogatories: 60 days, and no consent extensions

N.J. Ct. R. 4:17-4(b):

Except as otherwise provided by R. 4:17-1(b)(2), the party served with interrogatories shall serve answers thereto upon the party propounding them within 60 days after being served with the interrogatories. For good cause shown the court may enlarge or shorten such time upon motion on notice made within the 60-day period. Consent orders enlarging the time are prohibited.

Three things, and the third is the one that surprises people.

Sixty days. Generous, and it reflects how much New Jersey's uniform interrogatory forms ask for.

An extension requires a motion, on notice, for good cause — and the motion has to be made within the 60-day period. Waiting until day 65 to ask forecloses the request.

And consent orders are prohibited outright. In most states a phone call to opposing counsel solves a discovery timing problem. In New Jersey, for interrogatories, it cannot. The parties have no power to agree to more time; only the court can grant it, and only on a timely motion for good cause.

That prohibition is easy to overlook precisely because the practice it forbids is so routine everywhere else. An agreement between counsel to extend interrogatory answers is not merely unenforceable — the rule says such orders are prohibited.

Document requests: 35 days, or 50 for a defendant

N.J. Ct. R. 4:18-1(b)(2):

Procedure for Response. The party on whom the request is served shall serve a written response within 35 days after the service of the request, except that a defendant may serve a response within 50 days after service of the summons and complaint on that defendant. On motion, the court may allow a shorter or longer time.

The defendant's alternative is worth understanding. It is not an extension of the 35 days — it is a separate floor measured from a different event. A defendant served with a document request on the same day as the complaint gets 50 days from that date, which is longer. A defendant served with a request four months into the case gets 35 days, because the 50-day floor has long since passed.

Take whichever is later.

The rule also requires the person responding to swear or certify that the response is complete, in the form paragraph (c) prescribes — so a document response in New Jersey is a sworn document, not merely a lawyer's letter.

Requests for admission: 30 days, and silence admits

N.J. Ct. R. 4:22-1:

Each matter of which an admission is requested shall be separately set forth. The matter is admitted unless, within 30 days after service of the request, or within such shorter or longer time as the court may allow, the party to whom the request is directed serves upon the party requesting the admission a written answer or objection addressed to the matter, signed by the party or by the party's attorney …

This is the shortest of the three periods and the most dangerous, because the sanction is automatic. There is no motion, no order, and no hearing. Thirty days pass, and the matter is admitted.

An admission under this rule is not evidence to be weighed at trial. It removes the fact from the case.

The practical rule: calendar requests for admission first, ahead of interrogatories and document requests, even though they usually arrive together and look like the smallest pile.

What to do when the deadline is tight

Because consent will not extend interrogatory time, and because admissions are self-executing, the options are narrower here than in most states.

Move within the period. For interrogatories the motion must be made inside the 60 days. For admissions the court may allow a longer time, but you have to ask.

Answer what you can and object to the rest. A timely partial response preserves your position far better than a late complete one.

And know that failure to make discovery has its own rule. R. 4:23-5 governs what happens next, and its consequences escalate — dismissal or suppression without prejudice first, then with prejudice. It is a sequence with off-ramps, but each one closes.

How New Jersey compares

A short checklist

1. Do not use one deadline for all three devices. Interrogatories are 60 days, document requests 35, admissions 30.
2. Calendar the requests for admission first. Their 30 days is the shortest and the consequence of missing it is automatic.
3. If you need more time on interrogatories, file a motion inside the 60 days. An agreement with opposing counsel cannot do it — consent orders enlarging the time are prohibited.
4. For document requests, take the later of 35 days from the request and 50 days from service of the summons and complaint.
5. Remember the document response is sworn or certified, in the form the rule prescribes.
6. Answer what you can and object to the rest, on time. A timely partial response beats a late full one.
7. If you have already missed something, read R. 4:23-5. The consequences escalate in stages, and each stage has a way back until it doesn't.
