Unpaid invoice in Massachusetts 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 Massachusetts, small-claims cases are heard in the District Court, Boston Municipal Court, or Housing Court (small claims) and you can sue for up to $7,000.

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 Statement of Small Claim and Notice of Trial (also called the Statement of Claim and Notice form) in Massachusetts

  1. Identify the correct court and parties. Determine where to file: in the District Court or BMC where at least one plaintiff or defendant lives, works, or has a place of business, or where the rental property is located; or the Housing Court if it is a landlord-tenant matter. Gather the precise legal name and correct address of each party (per the mass.gov how-to page).
  2. Complete the Statement of Small Claim and Notice form. Fill out the Statement of Small Claim and Notice of Trial. The easiest method is the official online 'Small Claims Guide and File' guided interview, which generates the filled-in forms; you can then eFile or print them. The plaintiff is the party filing; the defendant is the party being sued.
  3. File the claim and pay the entry fee. File online (eFile), in person, or by mail with the Clerk-Magistrate's office of the proper court. mass.gov notes: 'when the papers are sent by mail to the clerk, the action is not commenced until the papers are actually received.' Pay the entry fee, which varies by claim amount (plus a $7 fee if you eFile).
  4. Receive docket number and trial date. The Clerk gives you a copy of your completed Statement of Claim and Notice showing the date and time of trial, plus a Docket Number, and the Clerk sends a copy of the Statement of Claim and Notice to the defendant.
  5. Prepare for and attend the hearing. About a week before trial, confirm with the Clerk that the defendant received the notice and whether an answer was filed; assemble evidence (contracts, receipts, photos, witnesses). Attend the scheduled hearing before the clerk-magistrate.

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 (M.G.L. c. 260, § 2)

Answering a lawsuit: Massachusetts does not require the defendant to file a written answer before the hearing; the defendant may simply appear at the scheduled trial. An answer is optional, and an optional Counterclaim must be filed with the Clerk at least two days prior to the hearing.

Serving the defendant: The court (Clerk-Magistrate's office) serves the defendant: after the plaintiff files, the Clerk sends a copy of the Statement of Claim and Notice to the defendant. The defendant must actually be notified by the Post Office; if the Post Office cannot serve the defendant, no judgment can be entered. About a week before the hearing the plaintiff should call the Clerk to confirm the defendant received the notice.

Appeals: The defendant has the right to appeal within ten days after receipt of the magistrate's finding by filing, in the court where the case was decided, a claim of trial by jury (or trial by a single justice); the appeal must be accompanied by a $25 entry fee and a $100 bond, which the court may waive for insufficient funds if the appeal is not frivolous. A plaintiff's right to appeal is very limited. Confirmed against the controlling statute M.G.L. c. 218, § 23, which is current; no superseding change was found.
