Delaware ยท Unpaid invoice

Unpaid invoice in Delaware 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 Delaware, small-claims cases are heard in the Justice of the Peace Court and you can sue for up to $25,000 (the Justice of the Peace Court cannot award more than this amount).

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 complaint (Civil Form No. 1) in Delaware

  1. Confirm the JP Court is the right forum. Determine whether the type and amount of your claim can be handled in the Justice of the Peace Court. Per the court: 'The Justice of the Peace Court may not award any amount exceeding $25,000.'
  2. Identify the defendant. Obtain and use the correct legal name and address of the defendant, and determine whether anyone other than the defendant needs to be named for service.
  3. Complete the complaint form. Obtain a complaint form (Civil Form No. 1). The court states: 'To start an action, you must fill out a complaint.'
  4. File the complaint and pay the fee. File the completed complaint with the Justice of the Peace Court and pay the applicable filing fee ($35-$45 for debt claims depending on the amount in controversy).
  5. Have the defendant served. After filing, the documents must be served on the defendant. 'After you have filed your complaint with the Court, the Court will attempt to serve (deliver the documents to) the defendant unless you tell the Court that you wish to hire a special process server.'

Filing fees: Filing fees for debt claims are roughly $35 to $45 depending on the amount in controversy. Verify the current fee with the court.

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

Answering a lawsuit: 15 days from receipt of the summons (debt and trespass actions)

Serving the defendant: After filing, the Court will attempt to serve the defendant unless the plaintiff hires a special process server.

Appeals: Most JP Court civil decisions (except landlord/tenant possession cases) may be appealed to the Court of Common Pleas in the county where the JP Court is located; a Notice of Appeal must be filed within 15 days.
