AES Registrations

The AES is a highly regarded studbook registering quality sport horses. With members throughout Europe, registration with the AES signifies a quality-bred horse. Simply send us the following:

  • The Covering Certificate fully completed with the horses dam and sire at the time of covering.
  • The ID markings diagram completed by a vet on the reverse of the Covering certificate - this must have been done while the foal is still with its mother, before weaning*.
  • If you have a vaccination card this can be inserted in the passport.
  • If the dam and sire are not registered with the AES we require a photocopy of their pedigrees and registration papers.
  • Any microchip or branding information.
  • Your name, address and contact number as the owner.
  • A cheque for the correct amount made payable to AES Ltd. (see payments page for correct amounts)

*If this has not been done and the horse is weaned, if your vet knows the foal and mother and can confirm the foal is out of the mare on the covering certificate, a letter confirming this from the vet is sufficient. If this is not possible please see section on DNA.

PLEASE NOTE: We require copies of actual registration documents for the dam and stallion if they are not already known by the AES (e.g. previous offspring has already been registered). WE DO NOT ACCEPT hand written pedigrees.

If all the above is in order with sufficient payment we are able to process passports usually within 2 weeks. Please alert us to any special circumstances e.g. if you are showing/competing, and need the passport urgently.

New Registrations

The following qualifies for studbook registration:

Full Studbook Offspring is by an AES graded Stallion with three generations of pedigree on both sides of the parentage.
Auxiliary Studbook Non AES Stallion but three generations pedigree; Or AES graded stallion but not three generations on both sides of the pedigree.
Foundation Studbook No pedigree available.

DEFRA update

New legislation by the Department for Environment, Food and Rural Affairs (DEFRA) regarding human consumption laws means that you may require additional paperwork to be added to your passport.

To check if you require this please look at the back of your passport - the back of the last page may be blank with "Official endorsements by Customs and Other Authorities". This means that the passport needs the DEFRA update - Section 9. To apply for this you can

Either:Send us a Stamped Addressed Envelope with a note requesting the DEFRA update, the number of passports you need it for and the name(s) of the horse(s) and we will send you the additional pages. You must then slot these in the back of the passport - please note there are three pages in total for the update, one page headed Section A and two pages headed Section B part 2.

Or: Send us the passport with a cheque and we will rebind the passport with the DEFRA update.

Late Registrations

Updating Owner Details - payments page

If you have bought a horse with an AES passport you need to update the Owner details to your own. To do this you must send us the passport with a cheque and a note detailing your name, address and contact number as the new owner. We will change the details and return the passport and we will also ensure it has the DEFRA update included in it.

Duplicate Passport - payments page

If you have a horse that you believe is registered with the AES but does not have a passport or any paperwork it is possible to apply for a duplicate passport.

You must forward us a covering letter confirming the name of the horse detailing why the passport has been lost. You must supply you name, address and contact number as the new owner. We will re-issue the passport to you; we usually hold copies of all ID markings and pedigree.

DNA Testing - includes passport and registration (incl. VAT) - payments page

If you cannot confirm the parentage of the horse by a covering certificate or Identification completed before weaning the next step for proof of pedigree is DNA testing.

You must tell forward us as much information and paperwork (as required in the Registration section) for the horse along with your cheque. We will check we already hold DNA for the mother and father and we will then forward you a DNA testing kit, this comprises of the following:

A sample bag, you must take some hair from the mane that includes the root and place it in the bag. This bag is addressed to go the Animal Health Trust for testing.
An ID sketch card for your vet to complete.
Instructions for carrying out the test.
You will send the hair sample to the AHT and return the ID card to us and we will await results. Please note that results can take over 1 month, we will notify you when we receive them.

If we do not hold DNA for the stallion or mother you will need to contact the owner and a DNA test must be carried out for them also.

Please note that DNA testing can only be conclusive if we can match DNA from the offspring with the believed parents. We may encounter problems if DNA held for the parents is an old sample. We endeavour to eliminate unnecessary cost for the owners of the horse however we can never guarantee results will be conclusive. Consequently refunds are not available on inconclusive DNA tests, as resources have already been used.
