Make sure that you use a bill of sale that includes a detailed description of the horse: name, age, height, gender, markings, whorls/ scars/brands, tattoo number, registration #, etc. There also should be a place to write in the detailed information of both the buyer and the seller–names, addresses, phone numbers, email addresses, etc.
When I shop for lower price horses I often bring 2 copies of my own BOS with me and it has blanks where that information can be filled in–just in case the seller does not have an acceptable document ready. Be sure that BOTH parties sign the document and that both parties have copies. Take a photo on your cell phone if it comes down to it. When money actually changes hands, I usually add a line on the contract stating that $XXXX was given or received and both parties can initial.
If you bring your own BOS, you can also add a clause where the seller warrants that they are the owner of the horse in question. If the seller isn’t the owner, I think it is reasonable to insist that the actual owner of the horse sign the paperwork before completing the transaction. Personally I also find it acceptable (for a lower priced sale) if the agent simply warrants that they are the authorized representative for the owner and lists the owners name and information as well. Keeping the true owner’s info a secret would not be acceptable.
Before you go look at a horse, I think it is useful to clarify what paperwork they have or don’t have on the horse. If it is an OTTB, I would definitely ask about the papers. In this day and age, a TB can be resold as officially retired from racing, so there is no need for people to withhold papers. If someone doesn’t have the papers, I would request the horse’s Jockey Club registered name and you can easily do some quick internet research to confirm the horse’s age and some of its history. If none of that is available, when you vet the horse have the veterinarian confirm the tattoo number. Having some link to the horse’s identity is important since there are many competition opportunities and awards open to OTTBs. If you ever plan to re-sell an OTTB, having the papers can be important to some buyers.
For other breed registries, I would simply ask about papers and let the seller know that it is important to you so that they have time to find and get together the paperwork. Many people forget about registration papers, and once the sale has gone through there is little motivation for people to find them. The papers themselves might not be important to you, but they are proof of the horse’s age and origin, which I think can be useful down the road. Registration papers don’t prove ownership, though.
Typically, the seller should provide a current coggins test. Double check that the horse and owner are identified correctly on the coggins and that the age matches up. Admittedly, I’ve simply gotten my Coggins on occasion when buying a horse at a lower price. I think it is also nice if they can provide a vet receipt with date for vaccinations. Again, when buying in a lower price range, you might not get that.
Remember, if you are purchasing out of state, you may need certain health papers to cross state lines. Also, be aware of what health documentation your boarding barn will require to accept your new horse.
