Contracts require both mutuality of assent and consideration to be enforceable. Legally sufficient consideration consists of bargained-for promises and obligations. If the consideration for the promise of one party is the promise of the other party, “there must be absolute mutuality of engagement, so that each party has the right to hold the other to a positive agreement. Both parties must be bound, or neither is bound.” (Am. Agric. Chem. Co. v. Kennedy & Crawford, 48 S.E. 868, 870 (Va. 1904)). A contract consisting solely of illusory promises will be deemed to lack consideration and will therefore not be enforceable. An illusory promise is one that—upon closer inspection—is not really a promise at all. An illusory promise leaves one party with complete discretion as to whether to perform the promise or abandon it. If the promise can be ignored at the will of the party, the promise has no value and will render the contract unenforceable.
Truist Bank learned this when the Western District of Virginia refused to enforce a boilerplate arbitration clause in a contract with one of its customers. In Kiser v. Truist Financial Corporation, the court denied Truist’s motion to compel arbitration, concluding that even if an arbitration agreement existed, it was illusory and therefore unenforceable.
