National Real Estate Exam (PSI)ContractsHard

A broker takes a listing under which the seller promises to pay a commission only if the broker actually produces a ready, willing, and able buyer, while the broker makes no binding promise to procure one. What best characterizes this type of agreement?

  1. AA unilateral contract
  2. BA bilateral contract
  3. CAn option contract
  4. DAn executory contract
Show answer & explanation

Correct answer: A. A unilateral contract

An open listing is typically a unilateral contract: the seller promises to pay commission only if performance (producing a buyer) actually occurs, and the broker makes no reciprocal binding promise to perform.

Why the other options are wrong

  • B. A bilateral contract requires mutual promises from both parties, which isn't the case in a listing where only the seller promises payment upon performance.
  • C. An option contract grants a right to purchase property, unrelated to a listing agreement's commission structure.
  • D. Executory simply means not yet fully performed; it doesn't describe the promise structure here.

Unilateral Contract

A contract in which only one party makes a binding promise, contingent upon the other party's performance of a specified act; commonly seen in open listing agreements.

  • Only one party is bound by a promise
  • The other party's performance, not promise, forms the contract
  • Common example: open listings and option contracts

Memory trick: Unilateral = one promise, waiting for action.
