The added benefit is that by doing that and making sure they know that if they don't remove the horses and don't pay, you're willing to go as far as you need to, to get rid of them and their horses, they may step up.
Otherwise, you file a lien according to your state/county/city's ordinances, take them to small claims court for non-payment and if they don't show up, or even if they do, frequently the judge will award custody of the horses to you. In most states, you have to sell the horses as public auction for the amount of the arrears and anything left over goes back to the horse owner. PUBLIC AUCTION doesn't mean the kill sale, you can hire an auctioneer and do it from your property but you have to be sure to follow the legal guidelines to publicize the sale. Or you can take them to the local sale barn which is what I would do and the chips will fall where they fall.
Good luck, these folks have realllllllly taken some serious advantage of you and the friendship.
