I let my friend borrow my atv to use for some farm work. We have a handwritten agreement signed by both of us stating that he would pay a monthly amount to use the atv. It also stated that at any time I wanted the atv back, it would be return in its original condition. My friend has not been paying the monthly payment and he will not return the atv to me. I have set up times for him to return it to me and he does not show. What is the best way to handle this? Any help would be appreciated.
