MBE Rules · Contracts

Termination of offer — revocation

The rule

At common law, an offer is freely revocable any time before acceptance, even if the offeror promised to keep it open — unless one of the irrevocability doctrines applies (option contract, firm offer under UCC §2-205, partial performance of a unilateral offer, or detrimental reliance).

In plain English

You can take back an offer anytime before the other person agrees to it, unless you've made a special promise or the other person has started to rely on it.

Worked example

The buyer offers to sell a car to the defendant and promises to keep the offer open for a week. Three days later, the buyer revokes the offer before the defendant accepts. The revocation is valid unless the defendant has relied on the offer.

Memory hook

Revocation Revolution: Offers can vanish before a 'yes'—unless locked by option, firm offer, partial performance, or reliance.

The trap

Students think: A promise to keep an offer open is binding. Wrong, because the promise alone isn't enough. The actual test is if an irrevocability doctrine applies.

How examiners test it

The MBE loves: an offeror promises to keep an offer open but revokes before acceptance. Trap: ignoring if an option contract, firm offer, partial performance, or reliance applies.
