New Hampshire ยท Unpaid invoice

Unpaid invoice in New Hampshire 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 Hampshire, small-claims cases are heard in the Circuit Court, District Division and you can sue for up to $10,000.

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 Claim Complaint (Form NHJB-2370-DE) in New Hampshire

  1. Complete the Small Claim Complaint. Fill out the Small Claim Complaint (NHJB-2370-DE) stating your relationship to the defendant, why money is owed, and the amount. Consumer-credit claims also need a Statement of Consumer Debt (NHJB-2875-DE). Claims over $10,000 must be filed as a civil writ.
  2. E-file through TurboCourt. E-filing is mandatory in small claims; self-represented filers use TurboCourt (Rule 4.1), unless an exemption is granted.
  3. Pay the filing fee. The claim is not considered filed until the fee is paid: $125 for claims of $5,000 or less, $180 for $5,001 to $10,000. Waivers require a showing of extraordinary circumstances.
  4. Court serves notice on the defendant. The court mails notice of the claim to the defendant by first-class mail (Rule 4.2). If it is returned undeliverable, you must supply a new address or arrange sheriff service, or the case may be dismissed after 60 days.
  5. Await the response and hearing. The defendant files a Response by the date on the notice. No response can mean a default judgment; a disputed claim is set for a hearing with relaxed evidence rules.

Filing fees: Fees are set statewide by the Judicial Branch, not the county: $125 for a claim of $5,000 or less and $180 for $5,001 to $10,000, effective 07/01/2025. A jury-trial or transfer fee is $145. Fees are waived only on a showing of extraordinary circumstances (Rule 4.1).

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: 3 years (RSA 508:4, I)

Answering a lawsuit: By the response date on the court's notice: 30 days from the mailing date when the defendant is served by first-class mail, or by the court's return date (at least 45 days out) if served as in other actions at law.

Serving the defendant: The court, not the plaintiff, first serves the defendant by mailing the notice first-class. If it is returned undeliverable, the court tells you, and you may supply a new address or request sheriff service under RSA 510. If you do not act within 60 days, the case is dismissed.

Appeals: Either party against whom judgment is entered may appeal to the New Hampshire Supreme Court on issues of law only, within 30 days of the judgment or the clerk's notice of it, whichever is later.
