registration is pretty meaningless and does little to nothing to prove ownership. Horses arnt titiled and there is no requiremnt to ever update registration papers with a breed registry. Breed registries have little to no legal standing especially if you have left a horse for what 6 months half a country away, and current person says you gave them the horse. Without a contract, or 6 months of canceled board checks you got an uphill battle. SOrry but thats probably reaity. How much are the horses listed for, offer to buy them. I imagine probably less than what FMV of board would have been.
