Wheeler Landlord-Tenant Lawyer, Illinois

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.

The act of changing a written contract when one of the parties can prove that the actual agreement was different than what's written down. The changes are usually made by a court when both parties overlooked a mistake in the document, or when one party has deceived the other.

A means by which one can legally take another's property without paying for it. The requirements for adversely possessing property vary between states, but usually include continuous and open use for a period of five or more years and paying taxes on the property in question.

Funds, usually amounting to one or two months' salary, frequently offered by employers to workers who are laid off. No law compels employers to provide severance pay, although the employer may be legally obligated to do so if it was promised in a contract or employees' handbook.

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 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.

A lump sum cash payment paid by a buyer when he or she purchases a major piece of property, such as a car or house. The buyer typically takes out a loan for the balance remaining, and pays it off in monthly installments over time.

Land and the property permanently attached to it, such as buildings, houses, stationary mobile homes, fences and trees. In legalese, real estate is also called real property.
