Draftmare, I agree with red mares, I think it is likely that you should obtain your own renters’ insurance policy.
This thread is a great PSA for boarders. In general, you own it, you insure it. Boarding barns do not typically have any coverage that protects the belongings of their clients.
This thread is also a great PSA for BOs. It is a good idea to let clients know up front that anything they store at the barn is stored at their own risk. I think it is wise to encourage your clients to make sure any valuable saddles/bridles are insured through their renters’ or homeowners’ insurance policy. It also doesn’t hurt to encourage your clients to store some of their items in a locked trunk and to be careful about what they choose to store at the barn.
Many farms do maintain a Care, Custody and Control insurance policy that would protect them if a horse was injured due to negligence in their care, however, that insurance policy does not cover above the value of the animal in question. So, depending on an owner’s preference, it does often also make sense to obtain major medical insurance on horses.
