Question 64

A contract in which only one party to the contract is legally bound to do anything is unilateral.

In a unilateral contract, only one party makes a promise or undertakes an obligation, while the other party is not bound to perform any duty. This structure allows for an enforceable agreement based on the action of the party who has made the promise.

A) aleatory.

An aleatory contract involves an agreement where the performance of one party depends on the occurrence of an uncertain event, such as insurance contracts. While it may involve one party being bound under certain circumstances, it does not fit the definition of a contract where only one party is obligated to act.

B) conditional.

A conditional contract is one where the obligations of one or both parties depend on the occurrence of a specific condition. This means that both parties may have obligations that are contingent on certain events, which does not align with the concept of a unilateral contract where only one party is obligated.

C) personal.

A personal contract generally refers to an agreement that involves personal services or specific relationships between the parties. This term does not denote the binding nature of the obligations and does not accurately describe a situation where only one party is legally bound.

D) unilateral.

A unilateral contract is defined by the fact that only one party makes a promise or is legally bound to perform an action, while the other party is not obligated to do anything. This directly fits the definition provided in the question, making it the correct choice.

Conclusion

The unilateral contract is the only option that accurately describes a scenario where only one party is legally obligated to perform. All other options either involve mutual obligations or conditions that do not pertain to the definition being tested. Thus, option D is definitively the correct answer.
