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 Oregon, 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. Oregon, like many states, has specific statutes that address the liability of equine professionals and activity sponsors. Under Oregon Revised Statutes (ORS) 30.687 to 30.697, commonly known as the Oregon Equine Activity Statute, there are provisions that limit the liability of equine owners and operators for injuries or death of participants resulting from the inherent risks of equine activities, provided that the equine professional has taken certain steps, such as posting warning signs and securing a signed release from participants. These laws recognize the inherent risks associated with equine activities and provide a level of protection for professionals and sponsors from lawsuits, as long as they are not negligent. It is important for those involved in equine activities in Oregon to understand these laws and ensure they are in compliance to minimize liability.
