I asked a similar question before but it’s still not clear to me:
If you buy a mare in foal at an auction, say a large Thoroughbred auction, is the stallion fee paid? Does the answer to this question depend on the auction house? How does the new owner get registration papers when the foal is born, that is, what paperwork would the new owner submit to the Jockey Club in order to register the baby?[/QUOTE]
With Thoroughbreds, entering a mare in a sale automatically makes the season payable and no guarantee. So when you purchase the mare, the fee has been paid (or will be paid out of sales proceeds). To register the baby, you will need to submit a Live Foal Report, then a Registration Application (and fee) plus the DNA kit to the lab. The Stallion Service Certificate will have been released on payment of the stud fee by the seller (either in advance of the sale on payment of the fee by the seller, or via proceeds from sale), and there will be no encumbrances to registration.
The stud fee is not owed by the purchaser, which I think is your big question. It will have already been paid.
