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 Colorado, 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. Colorado has specific statutes that address the liability of equine professionals and activity sponsors. One key piece of legislation is the Colorado Equine Activity Liability Act, which limits the liability of equine professionals and event organizers for injuries to participants resulting from the inherent risks of equine activities, provided that the required warning signs are posted and the proper contracts contain specific language as mandated by the statute. However, this immunity is not absolute, and exceptions exist where the equine professional or sponsor may still be held liable, such as through providing faulty equipment or failing to assess the participant's abilities accurately. It is important for those involved in equine activities to understand these laws and to ensure that their operations comply with state regulations and that they have appropriate liability insurance coverage.
