Who is considered a competent adult in legal terms?

In legal terms, a competent adult is defined as someone who has reached the age of majority, which is typically 18 years old in many jurisdictions, and is of sound mind. This means that they possess the ability to understand the consequences of their decisions, make informed choices, and manage their personal affairs.

Competence involves not just reaching a specific age but also the cognitive capability to comprehend and reason about different situations and their potential outcomes. This understanding is crucial when it comes to matters such as consent for medical treatment, entering contracts, or being held responsible for legal actions.

The other categories—individuals under 18, those deemed legally insane, and those intoxicated by substances—do not meet the criteria for competency as defined legally. Minors are not considered adults, and individuals who are legally insane or intoxicated lack the mental capacity required to understand and make responsible decisions.
