In which scenario is a contract likely to be considered void?

A contract is likely to be considered void when it includes concealed information because the integrity of a contract relies on transparency and mutual trust between the parties involved. If one party hides critical information related to the agreement, it undermines the validity of the contract by creating an imbalance in the knowledge and circumstances of the parties. Concealed information can lead to misrepresentation or fraud, which are grounds for a contract to be invalidated. The essence of a valid contract requires that both parties have full awareness of the facts surrounding the agreement; thus, any attempt to conceal significant details can result in the contract being deemed void.

In contrast, a contract signed by both parties, one that serves a legal purpose, and one where the terms are understood by both does not create the same risk of invalidation because these scenarios support the contract's legality and enforceability rather than detract from it.
