A covenant is precedent when by the terms of the contract it is to be performed before a covenant is to be performed by the adversary party. A contract to pay a certain amount when a certain tract is sold, makes the sale of such tract a condition precedent to such payment.1 An agreement that a contract should take effect only on approval by the attorney of one of the parties thereto is a condition precedent.2 Under a building contract requiring the contractor to give bond, giving such bond is a condition precedent, and his offer to begin work without giving bond cannot put the adversary party in default.3 Under a contract which provides for issuing a warrant and an assessment attached thereto when a contract for grading a street is completed, completion of such contract is a condition precedent to the issuing of such warrant.4 A covenant to furnish pipe for use in putting in a well is precedent to a covenant to use such pipe in the construction of the well.5
