Which of the following is NOT a requirement for consent to be legally valid?

Consent is a foundational concept in various legal contexts, especially in areas involving personal rights, medical treatment, and contract law. For consent to be legally valid, it typically must meet several criteria.

Voluntary consent means that the individual has willingly agreed to something without any coercion or undue influence. Informed consent requires that the individual has been provided with all necessary information about the implications and potential consequences of their consent. Additionally, consent must not be obtained through force or threats, ensuring that any agreement is made freely and without duress.

However, while written consent can be useful and may be required in some specific situations (such as in certain medical procedures or contracts), it is not a universal requirement for all types of consent. Verbal agreements or even implied consent can be legally recognized in many contexts. Therefore, it is not necessary for consent to always be documented in writing to be valid. This distinction clarifies why the option regarding the necessity for written consent is not a required criterion for all legal consent situations.
