Final answer:
In a bilateral contract, both parties must communicate their acceptance to each other, while in a unilateral contract, acceptance is typically communicated by the offeree performing the requested act.
Step-by-step explanation:
In the standard method of acceptance for bilateral contracts, both parties to the contract must express a clear intention to be bound by the terms of the contract. This means that both parties must communicate their acceptance to each other.
On the other hand, in the standard method of acceptance for unilateral contracts, acceptance is typically communicated by the offeree performing the requested act. The act of performance is considered to be acceptance of the offer.
For example, in a bilateral contract for the sale of a car, the buyer and seller would need to communicate their acceptance of the terms of the contract to each other, usually through a written agreement or verbal communication. In a unilateral contract, such as an offer of a reward for finding a lost item, the acceptance is usually communicated by the person finding the item performing the act of returning it.
