Sue for an Unpaid Invoice in Small Claims Court in Maryland

You did the work, sent the invoice, and the client stopped returning your calls. For sole traders, freelancers, and small business owners in Maryland, this is one of the most common reasons people end up in small claims court. If the unpaid amount is $5,000 or less, the District Court's small claims docket is built for exactly this situation.

Confirm Your Claim Fits

Maryland's small claims limit is $5,000, not counting interest, court costs, or attorney's fees recoverable by contract or law. If your unpaid invoice is higher, you have two options: file on the regular District Court civil docket (up to $30,000, with formal evidence rules and a $56 filing fee), or voluntarily reduce your claim to $5,000 to stay on the simplified small claims track.

The three-year statute of limitations under CJP § 5-101 runs from the date the invoice became due, not the date you sent it. If the client made a partial payment, the clock resets from the date of that last payment.

Name the Right Defendant

This is where many B2B claims fall apart. You need to sue the actual legal entity — not the person you dealt with, and not the trade name on the invoice.

Search the SDAT database (Maryland Business Express) for the business name. You need the exact registered name ("River Valley Design LLC," not "River Valley Design"), the entity's status (active vs. forfeited), and the resident agent name and address. Under Maryland Rule 3-124(d), you serve the resident agent, not just the business address.

If the entity's charter has been forfeited, you can still sue and serve substitute process through SDAT under Rule 3-124(o). A forfeited entity doesn't escape liability — it just changes the service route.

If you're suing an individual operating as a sole proprietorship with no formal business registration, serve them personally at their home or workplace address.

Send the Demand Letter First

A formal demand letter isn't legally required in Maryland before filing, but it strengthens your case in two ways. First, it shows the judge you tried to resolve this without the court's time. Second, it gives the debtor one last chance to pay — many do, once they see the certified mail envelope.

Include the invoice number, the amount due, a 10-to-14-business-day payment deadline, and a clear statement that you'll file in District Court if payment isn't received. Send it by certified mail with return receipt requested, and keep the green card when it comes back.

File Form DC-CV-001

Check "Contract" as the claim basis. In the facts section, state when the contract or agreement was made, what services you provided, when the invoice was due, and the exact dollar amount outstanding. Attach a copy of the invoice, any signed contract or written agreement, and your demand letter with the certified mail receipt.

The filing fee is $44. Add $20 per defendant for clerk certified mail service. File in a county where the defendant resides, carries on regular business, is employed, or habitually engages in a vocation; a corporation also may be sued where it maintains its principal office in Maryland.

What to Bring to the Hearing

Small claims hearings in Maryland are informal bench trials under Rule 3-701 — no jury, no formal discovery. The judge will give each side about 20 to 30 minutes. Bring originals plus two copies of:

• The contract, proposal, or written agreement
• The unpaid invoice(s)
• Proof of delivery or completion (emails confirming receipt of work, project files, delivery confirmations)
• Your demand letter and the certified mail return receipt
• Any correspondence where the client acknowledged the debt or promised to pay

Tell the story chronologically: the agreement, the work performed, the invoice sent, the silence, the demand letter, and the continued nonpayment. Let the documents do the heavy lifting.

If you need a structured approach to organizing the case from demand letter through hearing, the Maryland Small Claims Filing Guide includes a step-by-step filing roadmap, an entity verification checklist, and an evidence binder index built for exactly this type of claim.
