The Jockey Club does not print new owners' names on TB papers, but they will keep a record of ownership, and it is free. From their website FAQs at- https://www.registry.jockeyclub.com/...tryhelpdeskfaq
& ""How do I transfer ownership on my horse?
If the horse is already registered, submit a completed Transfer of Ownership form signed by the new owner or agent listing the new ownership information, the horse's name, pedigree and date of purchase.
Forms submitted via Interactive Registration do not require a signature.
If the registration is still in progress and papers have not issued, simply supply the correct ownership information in the spaces provided on the various forms utilized by The Jockey Club. For example, the Live Foal Report and Application for Registration can be used to report the ownership of a horse for which the papers have not yet issued.
The back of the Certificate of Foal Registration provides a number of blank spaces to record transfers of ownership when Thoroughbreds are bought and sold. The Jockey Club encourages all breeders and owners to faithfully record ownership transfers on the back of the Certificate of Foal Registration before the Thoroughbred changes hands.
To assure that future correspondence concerning the Thoroughbred is mailed to the correct address, The Jockey Club encourages owners to report transfers of ownership to the registry by either logging onto Interactive Registration and selecting "Transfer Ownership" or by calling the registry office and requesting a Transfer of Ownership form.
Although the term "ownership" is used, keep in mind The Jockey Club does not purport to maintain accurate and up-to-date records of ownership on Thoroughbreds. Rather, the transfer of ownership information is necessary to assure registry correspondence concerning the Thoroughbred reaches the appropriate parties responsible for transacting business with the registry.
The Jockey Club will not release the ownership information regarding a particular horse unless requested by order of a racing or court authority.
No fee is required to transfer ownership and DO NOT return the Certificate of Foal Registration.""
