Which of the following describes a situation where consent might not be valid?

Consent is considered valid when it is given voluntarily, without any form of coercion or undue pressure. In situations where a person feels forced to agree to something, such as during a police encounter or an interrogation, the validity of that consent can be called into question. If consent is obtained through manipulation, threats, or emotional pressure, it fails to meet the legal standard of being freely given. This is crucial in law enforcement, as any evidence obtained under these circumstances may be deemed inadmissible in court due to the lack of true consent.

In contrast, clear authority over the property indicates that the person has the legal right to grant consent, and documentation of consent can enhance its validity by providing a clear record. Being fully informed of one's rights further supports the validity of consent as it implies that the individual understands what they are consenting to. Therefore, situations where consent is coerced are the ones that most directly undermine its validity.
