I have an ethical/legal question I would like some help with.
My 5 horses had been in a pasture for about 8 months with the permission of the property owner. Her boyfriend brought a new horse to the pasture and turned him loose with my horses. Within a couple of days this new horses owner called and told me that my horses had kicked and bitten his horse to the point where he had to take the horse to the vet. The vet bill was $425. I told him that he should've known better than putting a new horse in a pasture like that, but that I would be willing to pay half the vet bill just because I wanted to be fair since they were my horses. He insists that I pay the entire bill and is threatening to sue me if I don't.
What would you do? How much of the responsibility for what happened is mine (my horses) and how much is his for putting his horse in the pasture like he did? What kind of a defense would you mount if you had to go to court over such an issue?
I'd appreciate any advice or counsel you can offer.
