How to File a Counterclaim in NJ Small Claims Court

When a Counterclaim Makes Sense

A counterclaim is your own claim against the plaintiff, arising from the same dispute. If a contractor sues you for $3,000 for unpaid work and you believe they owe you $2,500 for damage they caused to your property, you file a counterclaim for that $2,500. The judge hears both claims at the same hearing.

You are not required to file a counterclaim. But under New Jersey's Entire Controversy Doctrine (Rule 4:30A), all claims arising from the same transaction should be brought in the same lawsuit. If you skip the counterclaim now, you may lose the right to pursue it later in a separate case.

The Filing Mechanics

File your counterclaim through the JEDS portal (njcourts.gov) or in person at the Special Civil Part Clerk's office. The filing fee is $35 for claims up to $5,000. Your counterclaim must include:

• The specific dollar amount you are claiming
• A clear statement of the facts supporting your claim
• Your signature
• No confidential personal identifiers (Social Security numbers, full bank account numbers — redact these under Rule 1:38-7)

The deadline is the trial date itself — you must file on or before that date. Filing earlier gives the plaintiff time to prepare, which can work in your favor by encouraging settlement before the hearing.

What Happens to Your Case After Filing

The counterclaim amount determines where your case goes:

$5,000 or less: The case stays in the Small Claims Section. Both the plaintiff's claim and your counterclaim are heard at the same bench trial.

$5,001 to $20,000: The entire case transfers to the regular Special Civil Part (the "DC" track). Different rules kick in — written pleadings become mandatory, discovery is available, and the procedural complexity increases. You will also owe higher filing fees for the receiving track.

Over $20,000: The case transfers to the Superior Court Law Division. At this level, formal litigation rules apply in full. Individuals may represent themselves, while business entities generally must be represented by an attorney.

If your counterclaim is close to $5,000 and the transfer complications are not worth it, you can waive the excess and cap your demand at $5,000 to keep the case in Small Claims.

Serving the Plaintiff

After filing, you must serve a copy of the counterclaim on the plaintiff before the trial. Service between parties on interlocutory filings is done by regular mail or through approved electronic methods under Rule 1:5-1. Keep proof of service, such as a certificate of mailing or an approved electronic service record; a JEDS filing confirmation only confirms transmission to the court.

Counterclaim vs. Separate Lawsuit

Some defendants wonder whether they should skip the counterclaim and file their own separate lawsuit instead. In most cases, the counterclaim is the better path. It is cheaper (one $35 fee instead of a full $35 filing fee plus service costs for a new case), faster (decided at the same hearing), and avoids the risk that a judge in the separate case dismisses it under the Entire Controversy Doctrine for failing to join it with the original suit.
