We don't have any specific insurance for horses who are meant to be sold, but the existing Cavalassur insurances can be taken even if you are not the owner. You also can insure only your part of a co-owned horse.
Feel free to contact [email protected] for further informations about the stables the answer to your question depends on several points ;)
Il depends on the risk you want to cover. Actually, we mainly cover accidents, injuries, illnesses, surgeries or death that may happen to the insured horse. If this is what you need, no matter if the horse is yours or not, and if he's meant to be sold or not.
