The question of proof of ownership of horses came up somewhere else and maybe this needs a thread of it’s own.
The AQHA has explicit wording about registration certificates not being proof of legal ownership.
The person listed as owner is considered “owner of record” in the association, but the horse may have been sold several times or died and no one transferred the certificate into their name.
Many people don’t, because they are training the horse and selling it again soon, or just trading horses and, as long as they don’t need to show or breed, they don’t need for that horse to be registered in their name.
Each one needs to ask their attorney what their situation demands as legal proof of ownership of any horse, registered or not, or if you bred it.
I know of cases where bills of sale or cancelled checks were used as proof of ownership and I guess if you bred it, you have records of owning the mare/stallion or whatever contract you had about it with whoever bred it for you.
The gist of this is to remember that your name on a registration certificate alone is not considered legal proof, best I know.
If that were so, there are several horses I sold still with my name as “owner of record”.
No one transferred them into their name, but I can’t claim to own them, just because my name is still on those certificates.
