condition
A part of a contract that requires a party to do (or not do) something in order to make the agreement firm.
In an Agreement of Purchase and Sale, all conditions must be met for the contract to become firm and to prevent it from being nullified.
Two examples of typical conditions are requiring that a home inspection is performed and requiring that the buyer is able to arrange a mortgage loan.
Five elements are necessary to create a condition: what must be done, who must do it, who must pay for it, a deadline, and what happens if it is not done.
There are two kinds of condition, condition precedent and condition subsequent.
