Some states have a procedural tool—known as a suit on an account, a suit for an account, or a suit on a sworn account—that limits the evidence and pleading requirements for a creditor to establish its right to recovery on certain types of accounts in a lawsuit to collect a debt. These procedural tools are designed to reduce the cost of a creditor’s recovery of a debt on such accounts, and usually apply to transactions in which there is a sale upon one side and a purchase upon the other, and title to personal property passes from one to the other, creating a debtor-creditor relationship by a general course of dealing.

A sworn account is not an independent cause of action or basis for recovery, but requires the defendant to file a sworn denial of the account to avoid having the court grant judgment against the defendant early in the litigation process (summary judgment).

In Wyoming, the concept of a suit on a sworn account is not explicitly recognized as a distinct procedural tool in the same manner as it might be in other states. Wyoming follows the general rules of civil procedure which require a creditor to file a lawsuit and prove their case to recover a debt. The creditor must provide evidence of the debt and the debtor's obligation to pay. If the debtor disputes the debt, they must respond to the lawsuit, typically by filing an answer with the court. Wyoming does not have a specific statute or rule that allows a creditor to file a suit on a sworn account that would require the defendant to provide a sworn denial to avoid summary judgment. Instead, the creditor must proceed with the standard litigation process, which includes discovery, motions, and potentially a trial to establish the right to recovery. Debt collection in Wyoming is governed by both state statutes and federal laws such as the Fair Debt Collection Practices Act (FDCPA), which sets standards for the practices of debt collectors.
