The basis of a contract. Consideration is a benefit or right for which the parties to a contract must bargain; the contract is founded on an exchange of one form of consideration for another. Consideration may be a promise to perform a certain act -- for example, a promise to fix a leaky roof -- or a promise not to do something, such as build a second story on a house that will block the neighbor's view. Whatever its particulars, consideration must be something of value to the people who are making the contract.

A means of escaping an overly burdenome mortgage. If a homeowner can't make the mortgage payments and can't find a buyer for the house, many lenders will accept ownership of the property in place of the money owed on the mortgage. Even if the lender won't agree to accept the property, the homeowner can prepare a quitclaim deed that unilaterally transfers the homeowner's property rights to the lender.

The substitution of a new contract for an old one. A novation may change one of the parties to the contract or the duties that must be performed by the original parties.

Another term for real estate. It includes land and things permanently attached to the land, such as trees, buildings, and stationary mobile homes. Anything that is not real property is termed personal property.
