The WBFSH has recommended the following definition:

 

 

 

 

“Unless there was a contractual agreement at the time of sale of a pregnant mare, whereby the rightful breeder of the foal in utero sold with the mare is clearly defined, the rightful breeder of a foal is the entity that owned and/or had full rights to the mare (…) and registered the foal upon its birth with a studbook to obtain registration papers.”
