I leased a horse to another party. She breached lease agreement. Where do I sue her State or mine?
I leased a horse to another party. She flew to my residence, rode the horse and signed a written lease/purchase agreement. The agreement included terms for payment for me to transport the horse from Missouri to Ohio. The terms also included payment for round trip hauling of the horse if the lessee decided not to keep the horse. Now the lessee is refusing to pay the transportation fee agreed to in the signed agreement. Since we live in separate states what steps should I take to enforce the terms of the agreement?
