Litigation funding—also known as litigation financing or third-party litigation funding (TPLF)—provides a person or entity with the money to pay attorney fees, expert witnesses, and other costs necessary for litigation. Litigation funding is essentially a loan, secured by the proceeds of the expected settlement or collection of judgment in a lawsuit, and is designed to allow persons or entities without the necessary resources to pursue valid claims in litigation.

In Wyoming, litigation funding, also known as third-party litigation funding (TPLF), is a practice where a third party provides financial assistance to a litigant to cover legal expenses such as attorney fees and expert witness costs. This funding is typically provided in exchange for a portion of the proceeds from the settlement or judgment. Wyoming does not have specific statutes or regulations that directly address litigation funding for civil cases. However, the practice is generally permitted as long as it complies with other relevant laws, such as those against champerty and maintenance (which historically prohibited disinterested parties from funding litigation), usury (excessive interest rates), and ethical rules governing attorney conduct. It is important for parties involved in litigation funding agreements in Wyoming to ensure that the terms of the funding do not result in excessive control of the litigation by the funder or create conflicts of interest, particularly in relation to the attorney's duties to their client.
