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 Washington State, equine law encompasses various legal aspects related to horses, including ownership, sale, riding, breeding, racing, training, and other horse-related activities. Contracts are commonly used to outline the terms and conditions of these activities, ensuring clarity and legal enforceability between parties involved. Additionally, Washington has specific statutes that address liability issues related to equine activities. For instance, the Washington Equine Activity Liability Act (RCW 4.24.530) limits the civil liability of equine professionals and activity sponsors for injuries to participants that result from the inherent risks of equine activities, provided that the required warning signs are posted and contracts contain the appropriate warning language. However, this liability protection does not cover acts or omissions that constitute gross negligence or intentional misconduct. It is important for individuals and businesses engaged in equine activities to understand these laws and to consult with an attorney to ensure compliance and to address any legal issues that may arise.
