NH Equine Activity Liability: What Barn Owners, Trainers, and Riding Instructors Need to Know

Quick Summary

New Hampshire’s Equine Activity Liability Act (RSA 508:19) provides meaningful legal protection for equine activity sponsors, but those protections are not automatic. Barn owners, trainers, and riding instructors in Southern New Hampshire need to understand exactly what the statute covers, what it does not cover, and what steps are required to preserve the immunity it offers.

Summer is the busy season for equine businesses in New Hampshire. Lesson programs are running at full capacity, trail rides are booked, and boarding barns across Amherst, Hollis, Wilton, and New Boston are operating at their highest activity level of the year. For barn owners, trainers, and riding instructors, summer is also the season when liability risk is most elevated.

Here is what you need to understand about New Hampshire’s equine liability statute before your busiest months.

What RSA 508:19 Actually Says

New Hampshire Revised Statutes Annotated Section 508:18 is the state’s Equine Activity Liability Act. The core of the statute is straightforward: equine activity sponsors and equine professionals are not liable for an injury to or the death of a participant in an equine activity if the injury or death results from the inherent risks of equine activities.

The statute defines “inherent risks of equine activities” to include the unpredictable nature of horses, the potential for a horse to react in ways that may result in injury, and the risks of terrain and equipment. The law recognizes that horses are animals with their own instincts and that no amount of training or precaution can eliminate all risk associated with riding, handling, or working around them.

This is meaningful protection. If a student is thrown during a trail ride because the horse shied at a passing bicycle, and that student sues your barn, RSA 508:19 may provide a complete defense. The same would apply to a boarding client injured while handling their own horse in your facility if the injury resulted from the horse’s unpredictable behavior.

But the statute has important limits, and it requires you to take specific steps to preserve its protections.

Who Qualifies as an “Equine Activity Sponsor” Under NH Law

Not every person involved in equine activities qualifies for the statute’s protections. New Hampshire law defines “equine activity sponsor” as a person or entity that sponsors, organizes, or provides facilities for an equine activity, including but not limited to: pony clubs, riding clubs, school and college programs, therapeutic riding programs, and operators of equine facilities.

“Equine professional” is defined as a person engaged in the business of providing professional services involving horses, including training, teaching, providing horses for hire or remuneration, or selling horses.

If you operate a boarding barn, run lesson programs, teach clinics, or provide trail rides for compensation, you almost certainly qualify. Casual, non-commercial horse owners letting a friend ride do not fall under the statute in the same way.

Understanding your status under the statute matters because the protections only flow to those who qualify. If there is any ambiguity about your business structure, that ambiguity may be used against you in litigation.

Known Dangerous Conditions and Signage: Where Immunity Can Break Down

RSA 508:19 removes the immunity in specific circumstances, and one of them involves known dangerous conditions on your property.

The statute provides that an equine activity sponsor or professional can be held liable when they own, lease, rent, or otherwise are in lawful possession and control of land or facilities where a participant is injured because of a dangerous latent condition that was known to the sponsor or professional, and for which warning signs were not conspicuously posted.

This is an important distinction. The immunity provided by RSA 508:19 covers injuries from the inherent risks of equine activities. It does not protect you from liability for conditions you know about on your own property that create dangers beyond those inherent risks. If a section of your facility has a known hazard, such as a damaged fence line, unstable footing in an arena, or a rotted fence rail, and a participant is injured there because you failed to warn them, the statute will not protect you.

Practical implication: if you identify a dangerous condition on your property that you cannot immediately repair, post a clear warning to keep participants away from that area until it is fixed. And when the condition is repaired, document it.

This is not the same as a general notice that equine activities carry risk, which participants generally understand when they engage in the activity. It is about specific, known conditions that go beyond the ordinary inherent risks the statute contemplates.

Many barn owners assume that because the statute provides broad immunity, no further steps are needed. The statute does provide substantial protection, but that protection is not unconditional. Understanding where the exceptions apply is how you preserve the protections you have.

Participant Negligence vs. Sponsor Negligence: A Critical Distinction

The statute’s protection covers injuries resulting from the inherent risks of equine activities. It does not protect equine activity sponsors from their own negligence.

New Hampshire law identifies specific circumstances where the immunity does not apply:

• When the sponsor or professional provides faulty equipment or facilities and knows or should know of the defect
• When the sponsor or professional fails to make reasonable and prudent efforts to determine the ability of the participant to engage safely in the equine activity
• When the sponsor or professional intentionally injures the participant
• When the sponsor or professional is under the influence of alcohol or drugs

The phrase “faulty equipment or facilities” is broader than it may appear. If a participant is injured because a fence rail was rotted and broke under contact, or because a saddle girth was known to be frayed and snapped, or because your arena footing had a dangerous depression that you knew about and had not repaired, the statute will not protect you. That is a maintenance and inspection failure, not an inherent risk of equine activity.

The “reasonable and prudent efforts” requirement regarding participant ability is particularly relevant for lesson programs and trail rides. If you placed a beginner rider on a horse known to spook at traffic and that rider was injured on a road-adjacent trail, a court may find that you failed to appropriately match horse to rider. Documenting your rider assessment process, your horse evaluations, and your match decisions is good risk management practice.

What Contracts Can (and Cannot) Do

Many equine businesses use liability waivers and participation agreements to supplement the statute’s protections. A well-drafted equine liability agreement that incorporates the statutory warning, identifies the inherent risks of equine activities, and secures a participant’s acknowledgment can provide an additional layer of protection beyond what RSA 508:19 alone provides.

However, contracts have limits. New Hampshire courts scrutinize waivers for ambiguity and will not enforce provisions that release a party from the consequences of their own intentional acts or gross negligence. A waiver that is too broad, too vague, or that a court finds was not fairly disclosed may be set aside.

Having your liability agreements reviewed by an attorney familiar with NH equine law ensures they are enforceable and cover the scenarios most likely to arise in your operation. A generic form downloaded from the internet may not hold up in a New Hampshire court.

Practical Steps for Summer Risk Management

Beyond the legal requirements, here are the practical steps that protect equine businesses in Southern New Hampshire:

Review and re-sign all participant agreements at the start of the season. Do not rely on waivers from prior years. Have current participants sign updated agreements.

Conduct and document facility inspections. Inspect fencing, footing, tack, and equipment on a regular schedule. Keep a written log. Documentation that you identified and repaired a hazard before an injury is far more useful than documentation produced after the fact.

Assess and document rider ability. For lesson students and trail ride participants, record what assessment you conducted, what horse you matched them with, and why. If a new student signs up claiming prior experience, note what they told you and how you assessed it.

Confirm your insurance coverage. Equine liability insurance is not a substitute for legal compliance, but it is an essential complement to it. Confirm your coverage limits, what activities are covered, and whether any new offerings you have added this season are included in your policy.

Confirm your signage before peak season starts. Walk your facility. Check every entrance and every activity space. If signs are missing, faded, or in the wrong location, correct it now.
