Why It's Important To Have An Agistment Agreement (2026 Updated)

If you keep horses (or you manage land where other people's horses are kept), you'll know how quickly a "simple" arrangement can become complicated.

Maybe it starts with a friendly message: "Can I pop my mare on your paddock for a few months?" Or perhaps you're the one offering grazing and stabling as part of a small equestrian business.

Either way, agistment can work brilliantly - but only when everyone is on the same page about what's included, what's not, and who's responsible when something goes wrong.

That's where an Agistment Agreement comes in. In 2026, with rising costs, more professionalised livery and grazing arrangements, and increased expectations around animal welfare and insurance, having a clear written agreement is less "nice to have" and more "essential business hygiene".

Below, we'll break down what an agistment agreement is, why it matters, and what you should cover so you're legally protected from day one.

What Is An Agistment Agreement (And When Do You Need One)?

An Agistment Agreement is a written contract setting out the terms on which one party keeps a horse (or other livestock) on land owned or controlled by another party.

In practice, it might cover:

• Grazing only (for example, access to a paddock and water)
• Part-livery style arrangements (for example, grazing plus feeding, rug changes, turning out, or basic care)
• Shared facility use (for example, arena use, tack room storage, wash bays)
• Short-term stays (for example, a horse recovering after an event, or temporary relocation)

You generally need an agistment agreement whenever:

• someone else's horse is on your land (or land you manage);
• money changes hands (even informally);
• care tasks are shared, split, or unclear; or
• you want clarity on insurance, risk, and ending the arrangement.

Even if the horse belongs to a friend, a written agreement can protect the relationship. The goal isn't to make things "formal" in an awkward way - it's to avoid misunderstandings and disputes later.

Why Agistment Arrangements Get Risky Without A Written Agreement

Agistment often starts with good intentions. But without clear terms, you can end up dealing with problems you didn't agree to take on - and by the time something goes wrong, it's much harder to fix.

1. Confusion About Duty Of Care (And Who Does What)

One of the biggest pressure points is the day-to-day reality of horse care.

If the horse owner assumes you're checking water daily, feeding, and monitoring injuries - but you think you're only providing grazing - that gap can become a serious welfare issue (and a serious dispute).

A strong agreement sets out responsibilities clearly, such as:

• Who provides feed, hay, bedding, supplements, and medication
• Whether you are required to check the horse daily (and what that "check" includes)
• Who handles farrier, dentistry, worming, and vaccinations
• What happens in emergencies (including authority to call a vet)

2. Payment Disputes And "Hidden Extras"

Agistment fees can look straightforward until the extras creep in: extra hay during winter, emergency fencing repairs, arena lights, pasture rotation costs, or time spent catching a difficult horse.

Without an agreement, you may struggle to enforce payment for add-ons - or the owner may feel "surprised" and refuse to pay.

This is also where deposits and prepayments come up. If you take a holding deposit for a spot, or you charge in advance, you'll want your position to be clear (including whether the deposit is refundable and when). A lot of businesses run into trouble here, so it's worth thinking through Non-Refundable Deposits wording carefully.

3. Damage To Property And Facilities

Horses can (accidentally) do expensive damage - fencing, gates, stable doors, water troughs, and arenas can all be impacted.

Equally, an owner (or their visitors) may cause damage: leaving gates open, driving over wet ground, or mishandling equipment.

Your agreement should cover:

• Who pays for damage caused by the horse
• Rules for facility use (arena, jumps, tack rooms, parking)
• Whether certain areas are off-limits
• Any call-out charges if you have to fix urgent issues caused by the owner's conduct

4. Injury, Illness, And Liability Claims

When someone's animal is on your land, the big fear is: what happens if the horse is injured?

There's no single "one size fits all" answer. Liability depends on the facts, your role, what you agreed to do, and whether reasonable precautions were taken.

That said, a well-drafted agreement can reduce your risk by clearly stating:

• What you are and are not responsible for
• What the owner must do (for example, maintain insurance)
• What safety rules apply on site
• How incidents are reported and documented

It's also common to include appropriately drafted Limitation Of Liability Clauses, so expectations are set upfront. (This needs to be handled carefully - especially if you're dealing with consumers - so it's worth getting it tailored.)

5. "Is This A Lease?" Problems

A surprisingly common issue is that an informal grazing arrangement can start to look like a property arrangement - especially if someone has exclusive use of an area, keeps equipment onsite, or stays long-term.

You'll often hear people say "it's just a paddock rental", but legally, the structure matters because it affects rights, ending the arrangement, and what protections might apply.

Many agistment setups are closer to a contractual licence arrangement than a lease. If you want to understand how that differs in plain English, it's helpful to look at Licence To Occupy Agreements concepts - the key idea is controlling access and making sure you haven't accidentally granted stronger property rights than you intended.

What Should An Agistment Agreement Include?

A good agistment agreement is practical. It should reflect how things actually work day to day - not just what you hope happens on a perfect week in summer.

Below are common clauses you'll want to consider (and tailor to your exact setup).

Parties, Horse Details, And The Agistment Site

• Full legal names and contact details of the landholder/agister and the horse owner
• Description of the horse (name, passport details, microchip number where relevant)
• Address and description of the land/facilities included (and what is excluded)

Term, Fees, And Payment Mechanics

• Start date and whether it's fixed-term or rolling
• Agistment fees, when they're due, and how they're paid
• What's included versus chargeable extras (for example, hay, hard feed, bedding, turnout services)
• Late payment rights (for example, interest, suspension of services, or a right to terminate)
• Any deposit and the conditions for return (or non-return)

Services And Care Responsibilities

This is where you want to be extremely clear. For example:

• Is this DIY grazing (owner does daily care), or are you providing care services?
• Who checks fencing, water, and pasture condition?
• Do you provide daily checks - and if so, what does that include (eyes-on check, hands-on check, injury reporting)?
• Who arranges the farrier and vet, and who pays?

If you provide any services, spell out the boundaries. It's often better to say what you won't do as well as what you will do (for example, "we do not provide rehabilitation supervision or exercise").

Rules Of The Property

• Gates, fencing, and biosecurity rules
• Visitor rules (including children and dogs)
• Vehicle access and parking rules
• Arena use rules, jump use rules, and time slots if needed
• Storage rules (tack, feed bins, rugs) and what happens if items are left behind

Insurance And Risk Allocation

Insurance terms are often what separate a professional agistment agreement from a "quick template". Your agreement might address:

• Whether the owner must maintain horse insurance (including vet fees and third-party liability)
• Whether you hold public liability insurance for the property/business
• What happens if the horse causes injury or damage to third parties
• Any indemnities (where appropriate) and limits on liability

You should also ensure your agreement doesn't say something that contradicts your actual insurance policy conditions.

Emergency Vet Authority

If the owner can't be contacted, can you call a vet? Can you authorise treatment? Is there a spending cap?

This is one of those clauses you hope you never need - but when you do need it, you really need it.

Termination, Removal, And End-Of-Agreement Clean Up

Agistment arrangements end for all sorts of reasons: moving yards, pasture issues, behaviour problems, non-payment, or changes in your own land use.

Your agreement should set out:

• How much notice is required (and in what format)
• Immediate termination triggers (for example, welfare concerns, serious rule breaches, non-payment)
• What happens if the horse isn't collected on time
• Whether you can move the horse to another paddock/stable for safety reasons
• Cleaning obligations and removal of belongings

For the practical side of ending agreements cleanly, a structured approach like a Contract Termination Letter can help you stay consistent and reduce the risk of escalation.

How To Make Your Agistment Agreement Legally Enforceable In The UK

Having something "in writing" is a great start - but enforceability comes down to whether the document works as a proper contract, and whether it matches what you actually do in practice.

In simple terms, you want your agreement to be:

• Clear (no vague promises like "we'll keep an eye on the horse" without defining what that means)
• Consistent with your operations (don't promise daily checks if you're away three days a week)
• Fair (especially if the horse owner is a consumer, not a business)
• Properly agreed by both sides before the horse arrives

If you want a helpful baseline for contract fundamentals, it's worth keeping in mind the elements of What Makes A Contract Legally Binding - offer, acceptance, consideration, and intention to create legal relations.

Don't Rely On "We Agreed Over Text"

Yes, agreements can be formed in messages, and it's possible for emails to form part of a contract. But relying on a trail of informal messages is risky, because it's harder to prove what was actually agreed and what was just chat.

If you're tempted to keep it informal, it's worth remembering how often disputes turn on wording and notice - and that Email Contracts issues can get messy when the arrangement is ongoing and expectations evolve.

Get The Signing Right (And Keep A Clean Copy)

Most agistment agreements don't need to be witnessed like a deed. But you do want a clear signature process and a final PDF copy saved securely.

If you're ever dealing with a situation where a witness is required (for example, if you add a deed-based document to your setup), it helps to know Who Can Witness A Signature in the UK.

Make Sure Your Liability And Exclusion Clauses Are Fit For Purpose

It's common for agisters to want broad protection: "We're not liable for anything."

But in the real world, blanket exclusions can be unenforceable, unclear, or inconsistent with consumer protection rules. The better approach is to use carefully drafted limitations that reflect your actual risk profile and insurance.

This is one of the areas where generic templates can cause real harm - because they often include clauses that don't match UK law, don't match your service level, or create false confidence.

Key Takeaways

• An agistment agreement sets out the rules for keeping a horse on someone else's land, including fees, responsibilities, and what happens if something goes wrong.
• Without a written agreement, disputes often arise around care expectations, payment extras, damage to facilities, injury incidents, and how to end the arrangement.
• A strong agreement should clearly cover the term, price, inclusions/exclusions, care duties, property rules, insurance expectations, emergency vet authority, and termination process.
• Be careful not to accidentally create stronger property rights than intended - especially in long-term or exclusive-use arrangements.
• To be enforceable, your agreement needs to be clear, consistent with your real operations, properly agreed upfront, and drafted with realistic (and lawful) liability protections.
