How to Sue a Contractor in Wyoming Small Claims Court

A contractor who took your deposit and disappeared, left the job half-finished, or did work so poorly it needs to be redone — these are among the most common disputes in Wyoming small claims court. The same process works for collecting unpaid invoices from the other side: a small business owner who delivered goods or completed services and never got paid.

Does Your Claim Fit Small Claims Court?

Two threshold questions:

Is the amount $6,000 or less? Wyoming's small claims cap is $6,000 in principal. If your contractor walked off with a $4,500 deposit, that fits. If the total damage — deposit plus cost of hiring someone else to finish the job — exceeds $6,000, you can either waive the excess to stay in small claims or file on the general Circuit Court civil docket.

Is the statute of limitations still open? For a written contract (signed agreement, written estimate you both accepted), you have 10 years. For an oral contract (handshake deal, verbal agreement), you have 8 years. The clock starts on the date the contractor was supposed to finish or the date the breach became clear.

Step 1: Identify the Right Defendant

This step catches people off guard. If the contractor operates as an LLC or corporation, you must sue the legal entity — not the person's individual name. Search the Wyoming Secretary of State's WyoBiz database (wyobiz.wyo.gov) to find the exact registered name, filing ID, and registered agent address.

If it's a sole proprietor doing business under a trade name, sue the individual: "John Doe, d/b/a Doe Plumbing." Service goes to the individual personally.

Suing the wrong entity means your judgment might be unenforceable even if you win.

Step 2: Send a Demand Letter

While not legally required for contract disputes in Wyoming, a demand letter serves two purposes: it sometimes prompts payment without filing, and it shows the judge you tried to resolve things first.

State the exact amount owed, what it's for (deposit for work not performed, unpaid invoice for services delivered), a deadline for payment (15–30 days), and that you'll file in the Circuit Court if not paid. Send it certified mail with return receipt requested. Keep the green card when it comes back.

Step 3: Gather Evidence

Build your evidence packet before filing — you'll need three copies of everything for the hearing.

For homeowners suing contractors:

• The written contract or estimate (if one exists)
• Proof of payment — canceled checks, bank transfers, Venmo/Zelle confirmations
• Photos of incomplete or defective work (dated)
• A repair estimate from an independent contractor for the cost to fix or complete the work
• Text messages or emails discussing the project, deadlines, and complaints
• Your demand letter and certified mail receipt

For businesses suing for unpaid invoices:

• The contract, purchase order, or written agreement
• Invoices sent to the customer with dates
• Proof of delivery — signed delivery receipts, email confirmations, work completion records
• Payment records showing partial payments (if any) and the outstanding balance
• Demand letter and delivery proof

Step 4: File Form SC 01

Take your Small Claims Affidavit (Form SC 01) to the Circuit Court in the county where the contractor lives or where the work was supposed to be performed. In the affidavit, describe the work agreement, what was paid, what went wrong, and the exact amount you're claiming.

Sign the affidavit under oath in front of the clerk (or notarize it first if filing by mail). Pay the $10 filing fee and the sheriff service fee.

Step 5: Service and the Hearing

The sheriff or a private process server delivers the papers to the defendant. For a business entity, the papers go to the registered agent. Confirm service was completed by calling the clerk before your hearing date.

At the hearing, the judge asks questions directly. Walk through the timeline — when the agreement was made, what was paid, when the work stopped or the invoice went unpaid, what you demanded, and what the defendant did (or didn't do). Hand the judge your evidence set and reference specific documents as you go.

The judge weighs your evidence against whatever the contractor presents. For unfinished work, the damages are typically the cost to complete the job or the deposit that went unearned. For unpaid invoices, it's the outstanding balance.
