Ask to see the horse’s original passport before you commit, and arrange for a vet to check the microchip against the document. GOV.UK explains that the passport identifies the animal and must be provided when it is sold or given to someone else.[1]
Treat the checks as a separate part of your viewing, rather than something to squeeze in while loading the horse. This article offers information and questions to take to the relevant professionals, not legal advice or a substitute for a veterinary examination.
Start with the horse in front of you
Look through the passport beside the horse, with enough time to ask questions. Scottish Government guidance describes the information it contains, including the unique equid life number, microchip code, age and vaccination history.[8] Ask the seller to show you where those details appear rather than relying on the name written on the cover.
If a description or number puzzles you, make a note and ask the issuing organisation or your vet to explain it before proceeding. You do not need to decide for yourself whether an unfamiliar entry is harmless. A useful question is: “Can we check this together before I make any payment?”
Bring someone you trust if you would find a second pair of eyes helpful. Give them a specific job, such as recording the questions you still need answered, rather than asking them to make the buying decision for you.
Check the chip, not just the paperwork
GOV.UK lists asking a vet to scan the horse as one way to check its microchip.[1] Arrange this as part of your discussions with your own vet, and ask them to compare the scanned number with the passport. Looking at a number on a page does not itself check the animal standing beside you.
Ask your vet separately about a pre-purchase examination and what it can and cannot tell you. Keep the questions distinct: checking identity is one task; discussing whether a particular horse is suitable for your plans is another. Avoid treating a tidy document as the answer to every question about the purchase.
Write down any action that is still outstanding. If someone says they will sort out a discrepancy later, ask who will do it and how you will know it has been resolved before you proceed.
Do not treat the passport as proof of ownership
The Scottish Government explicitly says that a horse passport is an identification document and veterinary record, not an ownership document.[8] That distinction matters when you are being asked to hand over money.
Ask who owns the horse and who is authorised to sell it. If the person showing you the horse is acting for somebody else, ask them to explain the arrangement. Keep your questions and the answers with the other purchase paperwork, rather than relying on a conversation you may remember differently later.
If ownership is unclear or the answers conflict, pause and seek independent legal advice before paying. The passport issuer can help with its document and records; do not expect an entry in the passport to settle a disagreement about who can sell the horse.
Pause if the passport is missing
GOV.UK says to contact your local trading standards office for advice if the seller does not give you the passport.[1] The Scottish guidance also directs buyers to Trading Standards if somebody tries to sell a horse without one.[8]
A practical response is to stop arranging payment or collection until you have checked what needs to happen. Ask the seller which organisation issued the document and what steps they have taken. Contact that organisation using details you find independently, and explain exactly what you have been told.
You can be polite without agreeing to a rushed handover. “I need the passport question resolved first” is enough. If a viewing leaves you with unanswered questions, take your notes away and speak to the relevant adviser before making another commitment.
Plan the handover and the update
For buyers using the GOV.UK route, contact the Passport Issuing Organisation within 30 days to update the ownership details; Scotland’s guidance gives the same notification deadline.[1][8] Ask the issuer about its process before collection, including what it needs from you and how to keep the passport available during the update.
Check the guidance for your UK nation rather than assuming every detail is identical. GOV.UK links to the different national rules.[1] In Northern Ireland, DAERA says an Equine Establishment Number is needed for passport updates and explains the arrangements for people keeping a horse at livery.[4]
For your next viewing, start with three questions: can I see the original passport, can my vet check the chip, and who will handle any unresolved paperwork? Agree the next step before arranging collection. You can also explore the Equi Mind hub for other practical articles about life with horses.
