A more thorough explanation:

Adequate representation refers to the presentation of facts, either through words or actions, that are sufficient to induce someone to act, especially to enter into a contract. It is a manifestation to another that a fact, including a state of mind, exists.

For example, if a seller represents that a car has never been in an accident, this is an adequate representation. If the buyer relies on this representation and purchases the car, but later discovers that it was in fact in an accident, the buyer may have legal recourse.

Adequate representation is important in determining the validity of a contract. If a representation becomes a substantive part of the contract, its untruth may entitle the injured party to repudiate the whole contract. However, if it is only an independent subsidiary promise, its untruth may only give rise to an action for damages.
