This is very kind of you to do this but the only way for you to gain ownership of this horse is if there has been no contact or payment for the horse for over 30 days, a lien (agister’s or stablemen’s) would have to be processed by the barn/property owner who, I am sure, has no interest in doing so if you are paying for/caring for the horse. First step is to see if you can get the BO to do this (you can offer to do the legwork), depending on the state law you can either bid on the horse at auction if that is required, or just take ownership through a deal with the BO after the necessary legal requirements are met, some state’s require you to post notice in a public place (courthouse or newspaper) for the auction and a registered letter has to be sent to the last available address to the owner who abandoned him.

Satisfaction of the lien, it is actually easier in North Carolina because this is not a motor vehicle so unless the owner contacts the BO within 10 days of notice of lien (must be filed at courthouse), there is no need for a public sale, and a private sale can be negotiated.
