I am working on a contract for stud service. The stallion owner will get payment for stud fee and board at time of service. The mare will be included on the stallion report, but owner does not want to issue breeding certificate until birth. This has me nervous that I may not be able to register the foal. What are the reasons to withhold the certificate? I can't think of any that are good enough to outway the risk of potential registration problems. Any ideas?
