Other services

Irish issued passports.
Stallions and mares with a passport issued by Weatherbys (Thoroughbreds), Connemara Pony Society, Leisure Horse Ireland and Warmblood Studbook of Ireland can be endorsed onto Horse Source for breeding purposes.

The ownership on the passport must be up to date with the issuing passport authority.
An endorsement can be completed on Horse Source and sending the passport into HSI.
 
Foreign issued passports.
A foreign issued passport endorsement can be completed  on Horse Source and sending the passport into HSI.

It is a legal requirement to transfer the ownership of equines with the relevant Passport Issuing Authority (PIO) within 30 days of acquiring ownership.


When a horse is sold the seller should give the passport to the buyer. The buyer should then complete the Transfer of ownership application on Horse Source. 

For Non-HSI issued passports:

Horse Sport Ireland cannot process change of ownership requests for non-HSI passports unless the original passport issuing authority has already updated the passport.  

Naming applications can be completed online via Horse Source or, alternatively, by using the naming form available to download on Horse Source (be aware that for paper form applications there is an additional fee for manual processing). Applications will only be processed once the passport and payment have been received.

Can a horse’s name be changed?

  • In most cases, a horse’s name can be changed. If your horse has a prefix that you would like to remove, we need permission from the prefix owner. We will make contact with the prefix owner when you submit the application to change the name.
  • Mares and stallions that have progeny cannot have their names changed.

What is a prefix?

A prefix is a word (minimum of three letters) that an owner can purchase. This will give the owner sole use of that word in naming of all animals in the studbook. A horse named with a prefix cannot have their name altered unless permission is given by the prefix owner. If you are interested in purchasing a prefix, download the application form from Horse Source.

Why does the naming form require 4 name options?

We require multiple name choices in the event that the name you have selected is already taken by another horse.

If your passport has been lost, stolen or damaged, you can apply for a duplicate passport. The animal must have had a passport issued by HSI in order to request a duplicate.


To request a duplicate passport, get your vet to mark the horse up on a Horse Sport Ireland marking chart (your vet should have these) and complete the duplicate form. Send both into us and we can complete the duplicate. 


We cannot issue a duplicate passport for animals’ resident in the UK. If you require a duplicate passport for an animal in the UK, please contact a UK based passport issuing authority.
 

I just bought a new horse that didn’t come with a passport, do they have one already?

  • Check your equine details on the DAFM Equine Chip Checker here.
     

I wasn’t the owner in the old passport. What happens now?

If you were not the registered owner of the horse, you will have to submit a transfer of ownership form with your duplicate application. We will then have to contact the registered owner to request permission for the duplicate passport to be released. The registered owner has ten days to respond.

If the food change status has changed on your animal passport, please complete the following form.

This form allows equine owners to submit copies of the horse’s passport pages where the food chain status (stamp) has changed.

The studbook/PIO must be notified of these changes so the Department of Agriculture’s AIM system can be updated. If a stamp has been applied to the passport and the PIO has not been informed, the animal may be stopped at the port and denied onward travel or transportation, as the passport will not match the offcial digital record.

The PIO/studbook will always check for these updates where the passport has come in for other services. However, the stamp may have been applied more recently by the vet and therefore not yet notified to HSI. 

It is the responsibility of the animal’s owner/keeper to ensure the horse’s passport is correctly maintained.

 What you will need? 

  • Horse details
  • Ownership details
  • Picture/copy in your phone/on your computer of the medical page in the passport where the stamp and the Horse’s UELN can be clearly seen. 
  • Credit/Debit card (€15.00 record amendement fee)
