If you ride or own horses in the show jumping world, you know a horse is never just an animal in a stall. It’s the partner you’ve spent countless early mornings with, the one you trust over every fence, and often a member of the family. That bond is exactly what makes it so painful when something goes wrong. Maybe the horse you fell in love with during the trial vetted clean and came up lame a month later. Maybe you learned your trainer quietly took a commission from both sides of the sale, or a barn is refusing to release your horse over a disputed bill. In moments like these, you’re worried about your horse first and the money second, and you need someone who understands both. That’s where a California equine attorney can help. David Yoshida represents owners, riders, buyers, sellers, trainers and barns in equine disputes throughout California, with a focus on hunter/jumper and dressage horses.
David knows how this world actually works, from trials and vettings to imported warmbloods, trainers who double as agents, and leases that span a full show season. He also knows that behind every case is a horse who still needs to be cared for while the dispute plays out. So he starts by listening, then explains your options, and works to protect both your horse and your investment, often without ever setting foot in a courtroom.
Equine law covers the contracts, transactions and disputes that come with owning, buying, selling, boarding, training and caring for horses. For hunter/jumper and show jumping owners, those issues tend to look different than they do anywhere else: horses that change hands for significant sums, deals brokered by trainers and agents, horses shipped across states and countries, and careers that depend on soundness. As an equine lawyer, David handles:
The practice focuses on hunter/jumper and dressage horses and does not take thoroughbred racing matters.
Most horse sale disputes start the same way: the horse you bought isn’t the horse you were promised. It may have a hidden lameness, a prior injury that never came up, a stop at the fence the seller didn’t mention, or a soundness problem that was masked by medication during the trial or the pre-purchase exam.
California has a specific law for these sales. Under Business and Professions Code section 19525, which covers horses of any breed used for showing:
Beyond that statute, a buyer may have claims for fraud, concealment, negligent misrepresentation, breach of contract or breach of warranty, depending on what was said, written and promised. Not every disappointing purchase is fraud, so the details matter: the ads, texts and emails, the vetting report and radiographs, any drug testing, and who was really representing whom.
Leases are a big part of the show jumping world. They let a rider move up a level, compete a horse for a season, or try a horse before committing to buy, and they let owners keep a horse in work while sharing the costs. When a lease is clear, everyone wins. When it’s vague, or done on a handshake, it can quickly turn into a dispute over a horse that both sides care about.
A well-written horse lease agreement answers these questions before they become a fight. At a minimum, it should identify the horse, set the lease term and fee, spell out who pays for what, address injury, insurance and showing, and explain exactly how and when either side can end the lease. Before signing, many riders also arrange a pre-lease vet exam so everyone agrees on the horse’s condition at the start.
If a lease dispute is already underway, timing matters. A written lease generally has a four-year filing deadline in California, and an oral agreement generally has two years (Code of Civil Procedure sections 337 and 339). Gather the lease, payment records, vet records and messages, and talk with a California equine attorney before you stop paying, move the horse or take it back.
Choosing a barn and a trainer is one of the most important decisions a show jumping owner makes. You’re trusting them with your horse’s daily care, training and safety, often while you’re traveling, working or miles away. Most of these relationships run smoothly for years. But when trust breaks down, it can happen fast, and your horse is caught in the middle.
California gives boarding facilities, trainers and other livestock service providers a lien on a horse in their possession for unpaid care (Civil Code section 3080 and following). That lien can cover the services provided, reasonable charges that keep accruing while the barn holds the horse, other obligations under the contract, and the costs of enforcing the lien, including attorney’s fees. Veterinarians have a similar lien for care and boarding they provide (Civil Code section 3051).
But the lien has important limits. It only lasts while the barn keeps possession of the horse, and the barn generally can’t simply sell your horse. Before a sale, it needs a court order, a court judgment, or your written release. If a barn asks a court for permission to sell, the owner must be served with notice before the hearing, which gives you a chance to respond.
If a barn is holding your horse or threatening to sell it, act quickly. Don’t sign anything new or try to remove the horse yourself. Gather your boarding agreement, invoices, payment records and messages, and get advice about your rights and the barn’s. Often a dispute over the amount owed can be resolved, or the horse released, while the bill is sorted out.
David also works with barns and trainers who need to collect unpaid bills, enforce their lien the right way, or respond to an owner’s claims. Following the proper legal steps protects a facility from turning a collection problem into a lawsuit against it.
A clear boarding or training agreement prevents most of these problems. It should spell out the level of care, what’s included in the fee, who can ride and train the horse, how emergency and vet decisions are made, how billing and late payments work, and how either side can end the arrangement.
If you’re in the middle of a boarding or training dispute, a California equine attorney can help you understand where you stand before it escalates.
Few things are harder than watching a horse you love suffer, especially when you trusted someone to help them. Show jumping owners are often the ones who notice the smallest change in their horse’s gait or appetite, and who call the vet at the first sign of trouble. So when a horse is seriously injured or dies after veterinary care, the grief is often mixed with painful questions. Was it a misdiagnosis? A treatment error? A missed sign of colic or infection that should have been caught sooner?
A veterinary malpractice claim looks for honest answers to those questions. It generally asks whether the veterinarian met the standard of care a reasonably careful veterinarian would have followed, and whether falling short of it caused harm to your horse.
Because these cases depend on medical records, treatment timelines and expert opinion, it helps to act quickly. If your horse has passed, a necropsy can be one of the most important pieces of evidence, even though it’s a hard decision to make in the moment.
It’s also worth knowing how California values these losses. Although most owners see their horse as family, California law generally treats animals as property, and in McMahon v. Craig (2009), the court held that owners can’t recover for emotional distress or loss of companionship in these cases. That can feel unfair to anyone who has loved a horse. For a show horse, though, value can include its years of training, its competition record and its future potential, so the recoverable loss can still be significant. David will help you understand what your claim may include, and he’ll treat your horse’s story with the care it deserves.
Anyone who spends time around horses knows how quickly things can change. Even a well-trained, experienced horse can spook, kick or bolt, and riders, grooms, barn staff, spectators and visitors can be seriously hurt in an instant. When that happens, the injured person is often left with medical bills, time away from work or the saddle, and difficult questions about whether the accident could have been prevented.
Unlike many states, California doesn’t have a special equine activity liability statute. Instead, most of these cases turn on a few key questions:
An injured person may be able to recover medical expenses, lost income, future care, and compensation for pain and suffering, depending on the facts. Most injury claims in California must be filed within two years (Code of Civil Procedure section 335.1). If the injury happened on public property, such as a city or county equestrian center, a formal government claim usually has to be filed within six months.
Get medical care first. Then, if you can, take photos of the scene, the footing, the equipment and your injuries, collect names and contact information for witnesses, and keep any waiver, lesson agreement or boarding contract you signed. Avoid giving recorded statements to an insurance company before you understand your rights.
David represents both injured people and the owners, trainers and barns facing these claims, so he understands how these cases are built and defended from both sides.
The best equine dispute is the one that never happens. In the show jumping world, so much is still done on a handshake, a text or a quick conversation at the in-gate. That works until a horse goes lame, a payment is late, or someone remembers the deal differently. A clear, well-drafted legal contract protects your horse, your money and your relationships, and it gives everyone the same set of expectations from day one.
David drafts, reviews and negotiates equine legal contracts for owners, riders, trainers and barns, including:
If you already have a contract and something has gone wrong, David can review it and explain your rights before you respond, sign anything new, or move your horse.
When an owner dies or becomes incapacitated, a horse can’t wait for an estate to be settled. Someone still has to pay for board, training and vet care, and the horse’s value can change quickly. Because David also practices trust litigation, he can help families and trustees protect a horse during an estate or trust dispute, and enforce trusts set up for an animal’s care (Probate Code section 15212).
David Yoshida’s office is in Calabasas, at 4500 Park Granada, Suite 202, in The Park Calabasas, just off the 101 Ventura Freeway. That puts him close to some of Southern California’s most active equestrian communities, including Hidden Hills, Agoura Hills, Malibu, Thousand Oaks, Moorpark and the Santa Ynez Valley beyond.
Equine disputes are usually filed where the horse is kept, where the sale happened, or where the other party is located, so David works with owners and barns throughout California, and with clients on the show circuit who are often on the road. Wherever your horse is, the first step is the same: a conversation about what happened and what your options are.
You’ve given so much to your horse: the early mornings at the barn, the hours in the saddle, the long drives to shows, and the trust you’ve built one fence at a time. Your horse has given just as much back. So when a sale, a barn, a vet or a trainer puts that partnership at risk, it isn’t just a legal problem. It’s personal, and it can keep you up at night. Whether the deal fell apart last week or a dispute has been quietly building for months, you don’t have to carry it alone.
When you reach out, you’ll talk with David directly, someone who understands the show jumping world and genuinely cares about the horses in it. He’ll listen to the whole story, review the contracts, vet records and messages, and give you an honest assessment of where you stand. Sometimes the right letter resolves everything. Sometimes it takes more. Either way, you’ll leave the conversation with a clear plan and someone in your corner who’s focused on protecting your horse and your investment.
Just don’t wait too long. In horse cases, evidence disappears quickly: blood samples are discarded, horses are resold or moved, and memories fade. The sooner you talk with David, the more you can protect, for you and for your horse.

An equine attorney handles legal issues involving horses, including sale and purchase disputes, leases, boarding and training contracts, veterinary malpractice, horse-related injuries, and the contracts that prevent those disputes. In California, an equine attorney may also handle claims under Business and Professions Code section 19525, the state’s horse-sale law.
Yes. Under Business and Professions Code section 19525, every sale of a horse used for showing must have a written bill of sale stating the purchase price, signed by both the buyer and seller or their authorized agents. At a licensed public auction, a signed auction receipt can satisfy the requirement.
Not secretly. In California, an agent can’t receive more than $500 from anyone other than the person they represent unless it’s disclosed in writing and both sides consent in writing. A trainer who represents both buyer and seller without written consent from both is acting as an unlawful dual agent, and the injured party can recover three times their damages.
Start by gathering everything: the ads, texts and emails, the bill of sale, the pre-purchase exam and radiographs, any drug test results, and records of who paid whom. Depending on what was promised and concealed, you may have claims for fraud, misrepresentation, breach of contract or warranty, or violations of section 19525. Acting quickly helps preserve evidence like blood samples and vet records.
Not completely. A pre-purchase exam is only as good as what the vet could see that day. If a horse was sedated or medicated to hide lameness, or if the seller knew about a problem and concealed it, a clean exam doesn’t erase that. A blood sample pulled during the vetting can be key evidence later.
A California boarding facility can have a lien on your horse for unpaid care while it keeps possession of the horse (Civil Code section 3080 and following). But the barn generally can’t sell your horse without a court order, a judgment, or your written release. If a barn is holding your horse, get advice quickly.
It depends on the boarding agreement and what caused the injury. A barn can be responsible if it didn’t provide the care the agreement required or acted negligently, for example with unsafe fencing, improper turnout or a failure to call a vet. Many boarding agreements limit liability, so the contract’s exact wording matters.
Yes, if the veterinarian failed to meet the standard of care and that caused harm to your horse. California generally treats animals as property, so damages usually focus on the horse’s value and related costs, not emotional distress (McMahon v. Craig, 2009). For a show horse, value can include its training, record and earning potential.
Sometimes. California has no equine activity liability statute, so these cases usually turn on assumption of risk and negligence. An owner or barn can be liable for conduct beyond the normal risks of being around horses, such as ignoring a horse’s known dangerous behavior or failing to control it. Most injury claims must be filed within two years.
Often, but not always. A California waiver is more likely to hold up when it clearly describes the risks being released, names the right parties and is properly signed. Waivers generally don’t protect against gross negligence or intentional conduct.
Sometimes, but it’s much harder to prove. Oral agreements about leases, boarding or co-ownership can be enforceable, yet they often turn into disputes about who said what. And for a sale of a show horse, California requires a written bill of sale stating the price.
No. David’s equine practice focuses on hunter/jumper and dressage horses and does not take thoroughbred racing matters.
