The JC does not keep track of horse ownership the way all the other breed registries do. There is a place on the back of the papers for change of ownership. Name, address, date and signature of seller and that's it. You hand over the paper with the horse. No fees, no recording, no nothing. If somewhere along the line a transfer or two wasn't recorded, who cares? You have the papers. The last owner should of filled out the back and the horse and papers are yours. The next question is are they her papers? There is a lot of fraud with horse registration papers especially then there is no record of transfers. Was she raced? Is the tattoo # written on the papers and do they match her tattoo? You can also check the tattoo # with a service that will tell you who it belongs to. Just cross checking the year of birth might be enough.
