For a contract to be valid it must contain essential features. The feature that describes an expression of interest of one party to another and a subsequent act of indication to accept the terms outlines is:

Agreement or mutual consent.

Explanation:

Mutual consent or agreement is given expression by a valid offer by one party and acceptance by the other party.  These are then backed by adequate consideration, proof of the capacity of the contracting parties, and the legality of the subject of the contract.  Without the agreement or mutual consent between the contracting parties, the contract is not enforceable, ab initio.  It is this essential element of a contract that shows that the parties are interested in entering into some binding relationships for their mutual benefits.
