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 Oklahoma, equine law encompasses various legal aspects related to horses and horse-related activities. This includes the creation and enforcement of contracts for the sale, purchase, boarding, breeding, and training of horses. Additionally, Oklahoma has specific statutes that address the liability of equine professionals and activity sponsors. Under the Oklahoma Equine Activities Liability Act, certain liabilities for equine-related injuries are limited, provided that the equine professional has placed visible warning signs about the inherent risks of equine activities and has a written document signed by the participant acknowledging these risks. This law aims to protect equine professionals from lawsuits if a participant is injured during an equine activity, as long as there was no negligence or willful misconduct on the part of the professional. It's important for those involved in equine activities to understand these laws and to have proper contracts and liability waivers in place to mitigate risks associated with equine ownership and activities.
