Which action can make a contract voidable?

A contract can be made voidable when one party uses excessive influence. This means that if one party has a position of power or trust over the other party and uses that position to persuade or pressure them into entering the contract, the influenced party may have the option to void the contract.

In this context, excessive influence undermines the voluntary nature of the agreement. It suggests that one party did not enter the contract freely, which is a fundamental principle of contract law. The party who feels they have been excessively influenced may choose to affirm the contract or rescind it, depending on their preference and the situation involved.

In contrast, parties being of legal age is crucial for a contract to be valid, but it does not make a contract voidable. Lack of consideration means that there is no exchange of value, which would generally render a contract void rather than voidable. Signing without reading could indicate issues regarding informed consent, but it doesn't inherently suggest that excessive influence has occurred; therefore, it doesn’t constitute a basis for voiding the agreement.
