Unilateral Contract

Definition and meaning of Unilateral Contract in real estate.

A unilateral contract is a one-sided agreement where one party promises to perform an action in exchange for an actual performance from another party, rather than a reciprocal promise.

In more detail

In this type of contract, the second party is under no legal obligation to act, but if they choose to do so, the first party is legally bound to fulfill their promise. This differs from a bilateral contract, where both parties exchange mutual promises to perform.

A classic example in real estate is an open listing agreement, where a seller promises to pay a commission to any agent who brings a ready, willing, and able buyer, but the agents are not obligated to look for one. Another example is an option agreement, which gives a buyer the right, but not the obligation, to purchase a property within a set timeframe.
