New Jersey ยท Unpaid invoice

Unpaid invoice in New Jersey small claims

Client won't pay your invoice? Collect it in small claims.

If a client or customer has not paid an invoice for work you delivered or goods you sold, small claims court is a low-cost way to collect. You do not need a lawyer. The strength of your case usually comes down to clear proof: the agreement or terms, the invoice, evidence the work or goods were delivered, and a record of your attempts to collect.

In New Jersey, small-claims cases are heard in the Small Claims Section of the Special Civil Part (Superior Court, Law Division) and you can sue for up to $5,000 (including a suit to recover a security deposit).

Unpaid invoice: steps that matter

  1. Send a final written demand (a clear statement of what is owed and a payment deadline) and keep proof you sent it.
  2. Gather your contract or written terms, the invoice, delivery/completion proof, and any messages showing the other side accepted the work.
  3. Confirm you are within the statute of limitations below before you file.
  4. File in the correct court for where the defendant is or where the work happened, and keep every date and document together.

Filing your Small Claims Complaint (Form A) filed together with a Small Claims Summons and Return of Service (Form B) in New Jersey

  1. Complete the Small Claims Complaint and Summons. Fill out the Small Claims Complaint (Form A) and Small Claims Summons (Form B). Give your full name, address and telephone number; the correct name(s) and address(es) of the defendant(s), properly identified as an individual, sole proprietorship, partnership or corporation; the amount of money for which you are suing; and the reason the defendant owes you money. Do not include confidential personal identifiers (e.g., Social Security, driver's license numbers).
  2. Determine the correct county (venue). File in the Office of the Special Civil Part of the county where at least one defendant lives or where the defendant's business is located. If no defendant lives or is located in New Jersey, file in the county where the cause of the complaint occurred. A list of Special Civil Part Offices is available at njcourts.gov.
  3. Sign, date, and attach the filing fee or a fee-waiver request. Sign and date the completed complaint. Include the correct filing and service fees, or apply to the court to qualify as indigent so the judge may waive the filing fees. Make checks/money orders payable to 'Treasurer, State of New Jersey.'
  4. Submit the complaint and summons. File by uploading the documents into the Judiciary Electronic Document Submission (JEDS) system, by mail, or in person at the appropriate Special Civil Part Office.
  5. Await your court date. After filing, the court mails the complaint and summons to the defendant(s) and the plaintiff is notified of the trial date. The plaintiff must attend the trial at the time and date stated on the summons and bring all witnesses, documents, and evidence.

Filing fees: Filing and service fees are set locally and vary; confirm the current amount with the court. A fee waiver is available if you cannot afford the costs.

Deadline that applies to your unpaid invoice

An unpaid invoice is usually a contract or account claim. If you had a signed agreement or written terms, the written-contract statute of limitations below typically applies; a purely verbal deal usually falls under the oral-contract period. That statute is the deadline to file, so do not wait too long.

Written contract: 6 years (N.J.S.A. 2A:14-1)

Answering a lawsuit: No written answer is required in Small Claims; the defendant must appear in person at the trial on the date and time stated on the summons. Failure to appear may result in a default judgment.

Serving the defendant: After the complaint is filed, the court mails the complaint and summons to the defendant(s) (service is typically by certified and regular mail for a fee, or by personal service by a Special Civil Part Officer). The plaintiff does not serve the defendant personally.

Appeals: Either party may appeal to the Appellate Division of the Superior Court within 45 days from the date the final decision is rendered. A $250 filing fee is paid with the Notice of Appeal, plus a $300 deposit with the Clerk of the Appellate Division within 30 days; a trial transcript must also be obtained.
