Unpaid invoice in Maine 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 Maine, small-claims cases are heard in the Small Claims Court (a session of the District Court) and you can sue for up to $10,000 (effective January 1, 2026).

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 Claim (Form SC-001) in Maine

  1. Complete the Statement of Claim (SC-001). Fill out the Statement of Claim (SC-001) with a brief account of what happened, when, and what you want the court to do. Get the form free from any District Court clerk or the Forms page.
  2. Serve the defendant. Before filing, serve the defendant by certified mail with restricted delivery, hand delivery with an Acknowledgment of Receipt, or sheriff service in the defendant's county.
  3. File the claim and pay the fee. Once service is verified, file the Statement of Claim with the clerk within 20 days and pay the fee. If you cannot afford it, file an Application to Proceed without Payment of Fees (CV-067).
  4. Receive the hearing notice. Both parties get a Notice of Small Claims Hearing by mail with the date, time, and place. Be ready to present your case and evidence.

Filing fees: The fee to enter a small claims action is $55 (including a $15 mediation fee), set statewide by the Supreme Judicial Court (Administrative Order JB-05-26). Service costs are separate.

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 (14 M.R.S. § 752)

Answering a lawsuit: No written answer is required; the defendant must be prepared to respond at the hearing.

Serving the defendant: You must serve the defendant before filing, by certified mail with restricted delivery, hand delivery with an Acknowledgment of Receipt, or the county sheriff. File proof of service, then file the claim with the clerk within 20 days of verified service.

Appeals: Either side may file a Notice of Appeal within 30 days. A plaintiff may appeal on a question of law only; a defendant on a question of law or fact. Appeals are filed in the Superior Court.
