Ava Landlord-Tenant Lawyer, New York

A meeting of the minds. An agreement is made when two people reach an understanding about a particular issue, including their obligations, duties and rights. While agreement is sometimes used to mean contract -- a legally binding oral or written agreement -- it is actually a broader term, including understandings that might not rise to the level of a legally binding contract.

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.

The power of the federal or state government to take private property for a public purpose, even if the property owner objects. The Fifth Amendment to the United States Constitution allows the government to take private property if the taking is for a public use and the owner is 'justly compensated' (usually, paid fair market value) for his or her loss. A public use is virtually anything that is sanctioned by a federal or state legislative body, but such uses may include roads, parks, reservoirs, schools, hospitals or other public buildings. Sometimes called condemnation, taking or expropriation.

Anyone, including a corporation, who rents real property, with or without a house or structure, from the owner (called the landlord). The tenant may also be called the 'lessee.'

A contract in which an owner leases her house (usually for one to five years) to a tenant for a specific monthly rent, and which gives the tenant the right to buy the house at the end of the lease period for a price established in advance. A lease option is often a good arrangement for a potential home buyer because it lets him move into a house he may buy without having to come up with a down payment or financing at that time.

A statement included in a patent application that describes the structure of an invention in precise and exact terms, using a long established formal style and precise terminology. Patent claims serve as a way for the U.S. Patent and Trademark Office (PTO) to determine whether an invention is patentable, and as a way for a court to determine whether a patent has been infringed. In concept, a patent claim marks the boundaries of the patent in the same way as the legal description in a deed specifies the boundaries of the property.

A law adopted by some cities or towns with desirable vistas -- such as those in the mountains or overlooking the ocean -- that protects a property owner from having his or her view obstructed by growing trees. View ordinances don't cover buildings or other structures that may block views.

A restriction on the use of real estate that governs its use, such as a requirement that the property will be used only for residential purposes. Covenants are found in deeds or in documents that bind everyone who owns land in a particular development. See covenants, conditions and restrictions.
