Leases are contracts that allow people to use land for different purposes like living, working, or farming. They can cause disagreements between landlords and tenants because they mix property rules with contract rules. Leases are used for homes, businesses, and farms. This chapter talks about the basics of leases, like who gets to use the land and what happens when the lease ends. It also covers the rights and responsibilities of both landlords and tenants, how promises in the lease are enforced, and how leases can be ended.
