Equine law is generally defined as the body of law (statutes, court opinions) that governs the ownership, buying, selling, riding, breeding, racing, training, handling, insuring, and boarding of horses—and membership and participation in related organizations and activities. For example, contracts often define these transactions, relationships, and activities, and statutes often limit the personal injury liability of owners and operators of equine-related events and activities.

In Indiana, equine law encompasses various legal aspects related to horses, including ownership, sale, riding, breeding, racing, training, and boarding. Contracts are commonly used to outline the terms and conditions of these activities and relationships. Indiana, like many states, has an Equine Activity Liability Act (Indiana Code 34-31-5), which limits the liability of equine professionals and event sponsors for injuries to participants resulting from the inherent risks of equine activities, provided that the required warning signs are posted and contracts contain specific language. This law requires that certain warnings be provided to participants, and it outlines the responsibilities of both equine professionals and participants. However, the act does not grant absolute immunity, as exceptions exist where the equine professional may still be held liable, such as in cases of providing faulty equipment or failing to assess the participant's abilities accurately. It is important for those involved in equine activities to understand these regulations and to ensure that their practices comply with state statutes to minimize liability risks.
