Unpaid invoice in South Dakota 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 South Dakota, small-claims cases are heard in the Small Claims Court (within the Circuit Court system) and you can sue for up to $12,000 (verify the current limit with the clerk of courts).

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 UJS-008) in South Dakota

  1. Determine the correct county and confirm the limit. File either in the county where the defendant lives or in the county where the loss occurred. Because the $12,000 limit could change, the Guide advises verifying the maximum amount with the clerk of courts office. Parties must be at least 18 years old.
  2. Complete the required forms. The plaintiff (or their attorney) must submit a case filing statement (form UJS-232) and a signed, written statement of claim (form UJS-008) describing how the loss or damage occurred. UJS also offers a Guide and File system that generates completed forms.
  3. File with the clerk of courts and pay the fee. File the two statements, any supporting documents (receipts, cost estimates, etc.), and the addresses of the plaintiff and defendant with the clerk of courts. Fees and court costs must be paid by the plaintiff at the time of filing.
  4. Case is docketed and an answer/hearing date is set. After the clerk accepts the statement of damages claimed and required fees, the case is entered on the small claims docket and the clerk assigns the date the defendant must answer by, or the date and time of a hearing.
  5. Defendant is served notice. The clerk of courts sends the defendant notice of the lawsuit by certified mail. If the defendant does not receive notice by certified mail, the sheriff may need to personally serve the notice (at additional cost, with the plaintiff's authorization).

Filing fees: Filing fees and court costs are paid by the plaintiff at filing. Confirm current amounts with the clerk of courts.

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 (SDCL § 15-2-13)

Answering a lawsuit: Not a fixed number of days. The defendant must file an answer (form UJS-278) with the clerk of courts office within the time limit specified in the notice (the clerk assigns the date the defendant must answer by when the case is docketed).

Serving the defendant: The clerk of courts sends notice to the defendant by certified mail; if the defendant does not receive it by certified mail, the sheriff may need to personally serve the notice (additional fee, plaintiff authorization required).

Appeals: There is no appeal. A small claims judgment cannot be appealed to a higher court. (A defendant who wants a fuller proceeding may instead seek to have the action transferred from small claims court to circuit court under SDCL 15-39-57.)
