A condition precedent is an act or event, other than a lapse of time, which, unless the condition is excused, must occur before there is a duty to perform a promise set forth in the agreement. Here, there is a condition precedent to the formation or existence of the contract itself, so that there is no contract unless and until the condition occurs.
