A rental agreement or lease between a tenant and a new tenant (called a sublessee) who will either share the rental or take over from the first tenant. The sublessee pays rent directly to the tenant. The tenant is still completely responsible to the landlord for the rent and for any damage, including that caused by the sublessee. Most landlords prohibit subleases unless they have given prior written consent. Compare assignment.

A promise that pledges nothing, because it is vague or because the promisor can choose whether or not to honor it. Such promises are not legally binding. For example, if you get a new job and promise to work for three years, unless you resign sooner, you haven't made a valid contract and can resign or be fired at any time.

Any control over property. If you give away property but keep an incident of ownership--for example, you give away an apartment building but retain the right to receive rent--then legally, no gift has been made. This distinction can be important if you're making large gifts to reduce your eventual estate tax.

A way for two or more people to share ownership of real estate or other property. When two or more people own property as joint tenants and one owner dies, the other owners automatically own the deceased owner's share. For example, if a parent and child own a house as joint tenants and the parent dies, the child automatically becomes full owner. Because of this right of survivorship, no will is required to transfer the property; it goes directly to the surviving joint tenants without the delay and costs of probate.

Laws that limit the amount of rent landlords may charge, and that state when and by how much the rent can be raised. Most rent control laws also require a landlord to provide a good reason, such as repeatedly late rent, for evicting a tenant. Rent control exists in some cities and counties in California, Maryland, New Jersey, New York and Washington, D.C.

An unconditional right to receive real property at some point in the future. A vested interest may be created by a deed or a will. For example, if Julie's will leaves her house to her daughter, but the daughter gains possession only after Julie's husband dies, the daughter has a vested remainder in the house.

A payment required by a landlord to ensure that a tenant pays rent on time and keeps the rental unit in good condition. If the tenant damages the property or leaves owing rent, the landlord can use the security deposit to cover what the tenant owes.
