My husband agreed to allow someone to rent a portion of the shop where he stores his semi tractor. My husband rents the shop from a third individual. The "tenant" has a mechanic's business inside that shop, but has not kept his part of the deal. Never pays rent, but has serviced my husband's semi and pickup with no labor costs. He owes much more than he has "traded". Part of the agreement was that he would keep the shop clean. He has also not kept that part of the bargain. There is no written agreement and my husband now wants to change locks and keep the equipment this person has in our rented shop. Can he do this?
