Question 95

Performance obligations of the parties differentiate a bilateral contract from a unilateral contract.

In a bilateral contract, both parties make mutual promises to perform certain obligations, whereas in a unilateral contract, only one party makes a promise in exchange for the performance of an act by the other party.

A) number of parties involved

This option is incorrect because both bilateral and unilateral contracts can involve two parties. The key distinction lies not in the number of parties but in the nature of the obligations created by the contract.

B) performance obligations of the parties

This option is correct as it accurately highlights the primary difference between bilateral and unilateral contracts. In a bilateral contract, each party is obligated to perform their respective duties, while in a unilateral contract, one party's obligation is contingent upon the other party's performance.

C) relative value of the object of the contract

This option is incorrect because the relative value of the contract's object does not differentiate between bilateral and unilateral contracts. Both types of contracts can involve varying values and the comparison of value is not a defining characteristic.

D) type of property specified in the contract

This option is incorrect as well because the type of property involved in the contract does not determine whether it is bilateral or unilateral. Both contract types can pertain to various forms of property and the distinction is based on the obligations of the parties, not the property type.

Conclusion

The distinguishing feature of a bilateral contract is the performance obligations of the parties, where both are bound to fulfill their promises. In contrast, a unilateral contract only binds one party to perform upon the other party's act. This fundamental difference in obligations clearly sets apart bilateral contracts from unilateral ones, making other options irrelevant in this context.
