Are there any horses who don’t need passports?

pony society records the records of the Verderers of New Forest the studbook of New Forest pony breeding and Cattle society or the lists of the National trust in the case of the Konik equines. In Wales the Carneddau ponies are covered by the exemption. 
Being of one of these breeds alone is not enough to qualify for an exemption. The animals in question must be listed by the respective societies as living in a designated area without domestication. Any horse eligible for the exemption must be identified in one of these lists by six months of age or the 31st of December of its year of birth whichever is later. 
The UK passport legislation allows an exemption for these animals for only as long as they remain in their designated areas and are not brought into domestic use. 
What happens if these exempt horses are sold or need veterinary treatment?
If an owner wishes to sell an animal then it becomes necessary to formally identify that horse. In the New Forest for example an owner may sell a foal listed as exempt without a passport if the foal has been born on the New Forest to a mare that has
been living on these lands. And it is sold in its year of birth through the Beaulieu Road Sales held in the New Forest. But critically they must be presented for sale with a completed passport application so that when the foal is sold the auctioneer must stamp a completed passport application. This is so that the pony is not sold without proper identification. The only exception to this is if the horse is less than a year old and is being sold directly for slaughter.
