Landlord-tenant law is the collection of laws that govern the relationships between and rights of both landlords and tenants. This includes laws for commercial and residential real estate.
Disputes between landlords and tenants frequently occur, so landlord-tenant law is often used to help work these situations out when they come to court.
There are many different things that can cause a conflict between landlords and tenants; for example, non-payment of rent, noise complaints, landlords demanding entry into the buildings, cleanliness, etc. Landlord-tenant law provides guidelines for all of these situations and many more.
Tenants have certain rights and privileges, and landlords do as well. Perhaps the most important landlord-tenant law is that tenants are only entitled to occupy the property for the duration of the lease, and while rent is being paid.
