Warranty in Horse Sales: Private, Commercial, and When You're Considered a Professional Seller

Between private individuals, warranties can be excluded, but not when selling to a consumer. The grey area lies in determining when someone is considered a professional seller, a decision not made by a form, but by the overall circumstances.

Warranty in Horse Sales: Private, Commercial, and When You're Considered a Professional Seller — AI-generated image

Warranty claims are often why your phone rings six weeks after a sale. The horse is lame, coughing, or won't load, and the buyer wants to know who's responsible. The answer hinges on one crucial question: Who sold to whom?

Private to Private

When two private individuals sell a horse to each other, they are permitted to contractually exclude warranty claims. This clause is found in almost every template agreement, and it generally holds up.

However, three things it never covers are:

Fraudulent Concealment. If you know about a defect and deliberately conceal it, you remain liable. This is stipulated in § 444 BGB.
Warranted Qualities. Whatever you've agreed upon in the contract regarding the horse remains binding. The Federal Court of Justice ruled in 2006 that a general exclusion of liability does not override an agreement on specific characteristics (VIII ZR 92/06).
Damage to life, body, and health, as well as damages caused by gross negligence or willful intent.

This leads to an uncomfortable truth for sellers: the more you promise in your advertisement, the less effective your warranty exclusion becomes. And for buyers: if it's not in the contract, it's not a warranted quality, no matter how it sounded in a chat.

Professional Seller to Consumer

If a professional seller sells to a private individual, an exclusion of warranty is not possible. The rules of consumer goods sales apply, and these cannot be deviated from to the detriment of the buyer (§ 476 BGB). Depending on the specific case, a shortening of the limitation period might be possible, but only under strict conditions and never as a quiet clause in the fine print.

Furthermore, there's the burden of proof: if a defect appears within the first few months after delivery, it is presumed that it already existed at the time of handover. The seller must prove the opposite, and with a living creature, this proof is notoriously difficult to provide.

When Are You Considered a Professional Seller?

According to § 14 BGB, a professional seller is someone who, when concluding a transaction, acts in the exercise of their commercial or independent professional activity. Therefore, the decisive factor is not whether someone has registered a business, but how they actually present themselves.

Courts look at the overall picture: How many horses are sold per year? Are they specifically bought, trained, and resold? Is there a website, regular advertisements, a reputation in the market? The more systematic and continuous the activity appears, the more likely it is considered commercial, even without a business license.

For breeders, this means: if you regularly sell foals, you are, in doubt, selling as a professional. For riders who part with their own horse after many years, however, nothing changes.

What This Means for Your Contract

As a private seller: Document known defects and only promise what you can deliver. The exclusion of warranty is part of it, but it's not a standalone solution.
As a professional seller: Omit the exclusion; it would be ineffective. Instead, meticulously document the horse's condition, ideally with a pre-purchase examination (PPE) whose report becomes part of the contract.
As a buyer: Everything important to you must be explicitly stated in the contract. After that, it's a warranted quality and no longer just a topic of conversation.

What a Buyer Can Demand

If a defect exists and the warranty applies, the buyer is entitled to the rights outlined in § 437 BGB: subsequent performance, rescission of the contract, reduction of the purchase price, and under certain circumstances, damages.

With horses, the first step is tricky. Subsequent performance would mean rectification or delivery of a defect-free item. A horse cannot simply be exchanged, and whether a treatment is reasonable as a rectification depends on the individual case. In practice, therefore, it usually comes down to rescission or reduction, and both are typically decided in court or through a settlement.

The claims generally expire two years after handover (§ 438 BGB). Between private parties, this period can be shortened or entirely excluded; when selling to a consumer, it cannot be arbitrarily altered.

Three Common Dispute Scenarios

Back Findings. The horse shows problems after a few weeks, and X-rays from the pre-purchase examination reveal changes in the spinous processes. The question is never whether a finding exists, but whether it caused issues at the time of handover and if it impedes the agreed-upon purpose of use.

Skin Problems Not Apparent in Winter. Sweet itch doesn't show itself in February. Here, what the seller knew is decisive. If they knew and didn't mention it, the exclusion of warranty won't hold up.

Behavior. Won't load, not good with the farrier, spooky on hacks. Such characteristics are only considered a defect if they were agreed upon or if the seller promised the opposite. That's why it pays to be honest in the contract, rather than overly generous in the advertisement.

The Same Advice for Both Sides: Write It Down

Most of these disputes arise not from malice, but because four months later, no one remembers what was said at the stable gate. A contract that specifies the horse's condition, its intended purpose, and any known limitations protects both parties: the seller from claims they couldn't anticipate, and the buyer from promises that no one can prove anymore.

Common questions

Can I exclude warranty claims when selling a horse?

Between private individuals, yes. If you sell as a professional to a private individual, an exclusion is ineffective. Even between private parties, the exclusion does not apply to fraudulently concealed defects or to qualities you have expressly agreed upon.

When is a horse seller considered a professional?

According to § 14 BGB, a professional is someone who concludes a transaction in the exercise of a commercial or independent professional activity. A business license is not required for this. Courts assess the overall picture: number of sales, systematic buying and selling, market presence.

Who has to prove that the horse was already sick at the time of purchase?

When a professional sells to a consumer, for defects that appear within the first few months after handover, it is presumed that they already existed at the time of handover. The seller must refute this. Between private parties, however, the buyer bears the burden of proof.

What helps the seller besides an exclusion of warranty?

Honesty in the contract. Known pre-existing conditions and quirks should be included, as well as a sober description of the training level. A pre-purchase examination (PPE), whose report becomes part of the contract, documents the condition on the day of handover.
