Unpaid invoice in Maryland 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 Maryland, small-claims cases are heard in the Small Claims division of the District Court of Maryland and you can sue for up to $5,000 (money only; claims from $5,001 to $30,000 are heard as regular District Court civil cases).
Good to know: Small claims are not a separate court; they are handled as a simplified, less formal track within the statewide District Court of Maryland. A case qualifies as a small claim only if it is for $5,000 or less, for money only (not return of property or performance of a service), and does not involve discovery. The District Court itself can hear civil claims up to $30,000; claims over $5,000 (up to $30,000) are tried as regular civil cases, not small claims.

- Confirm you are within the statute of limitations below before you file.

Filing your Civil Complaint (Form DC-CV-001) in Maryland
- File the Complaint (DC-CV-001). Complete the District Court Civil Complaint form (DC-CV-001), naming the correct defendant, and file it with the clerk at any District Court location. Forms are available at the clerk's office.
- Pay the filing fee. Pay the filing fee at the time of filing. Fee amounts are set by the District Court's Civil Cost Schedule (DCA-109); check the current schedule when you pick up your forms. If you cannot afford the fee, file a Request for Waiver of Prepaid Costs (CC-DC-089).
- Choose a method of service and the court issues the Writ of Summons. On the Complaint, select how the defendant will be served (certified mail, sheriff, or private process). The court then issues a Writ of Summons to officially notify the defendant that a suit has been filed.
- Have the defendant served. Serve the defendant by one of the three methods. You may not serve the defendant yourself; service must be by certified mail (clerk mails it), the sheriff, or an uninvolved adult 18 or older / private process server.
- Submit Proof of Service. File proof that the defendant was served: the green certified-mail return receipt, or an affidavit of service (Proof of Service form DC-CV-002 / Affidavit of Service) for sheriff or private process. Trial is normally set within 60 days of when the complaint was filed.
Filing fees: Filing fees are set by the District Court Civil Cost Schedule (DCA-109); confirm the current amount with the clerk. A fee waiver (CC-DC-089) is available.
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 (Md. Cts. & Jud. Proc. § 5-101)
Answering a lawsuit: 15 days from the date the defendant receives the summons to file a Notice of Intention to Defend (60 days for out-of-state defendants and those with resident agents)
Serving the defendant: The plaintiff may not serve the defendant personally. There are three methods, selected by checking a box on the Complaint: (1) certified mail (the clerk creates the summons and mails it; the green return receipt is proof of service); (2) sheriff (hand delivery, returns an affidavit of service); or (3) private process (an uninvolved adult 18 or older, or a private company, hand-delivers the summons and files an affidavit of service).
Appeals: Either party may appeal to the Circuit Court by filing a Notice of Appeal (form DC-CV-037) in the District Court within 30 days after entry of judgment. A small claims appeal ($5,000 or less) is heard de novo, meaning a completely new trial in the Circuit Court (total appeal fee $175).
