What is the minimum age for a child to provide informed consent in most jurisdictions?

In most jurisdictions, the minimum age for a child to provide informed consent is typically set at 18 years old. This is grounded in the understanding that individuals under this age are generally considered minors who do not possess the legal capacity to make certain decisions independently. The age of 18 is widely recognized as the point at which a person is legally deemed an adult and can make informed decisions about their health, welfare, and legal matters.

While there may be some exceptions depending on specific circumstances or local laws—such as in areas where minors can consent to certain medical treatments or services under particular conditions—the overall legal framework tends to establish 18 as the standard age for informed consent. This ensures that individuals have the cognitive and emotional maturity required to fully understand the implications and consequences of their decisions.
