Apply for a prefix

Horse Sport Ireland offers breeders the facility to register a prefix for a fee of €79.95 (inc. VAT).

  • The prefix should be a geographical name or a distinctive word or name.
  • A prefix may have a maximum of 20 letters, and two word prefixes are not accepted.
  • Initials can be accepted, with a minimum of three letters.
  • Breed names are not allowed.

The individual names of ownership of the prefix must be stated in the application form. Please note that it is advisable to mention all the individuals (i.e. members of the family) that will own the prefix as there is a cost to add names to the ownership of the prefix once the certificate of ownership of the prefix has been issued.

The fee of €79.95 is an once off payment.

For changes to the name of existing prefixes or to transfer the owner of the prefix to another person there is a charge of €43. Further charges may apply if the prefix is to be used with other Societies. Please note, animals should not be registered using a prefix until the prefix confirmation has been received.
