Parental consent refers to the permission that a parent or legal guardian must give for a child to participate in certain activities or make specific decisions. This can include medical treatments, school trips, or legal agreements. The requirement for parental consent is designed to protect minors, ensuring that adults are involved in important decisions affecting their well-being. In many countries, the age at which a person can give their own consent varies, often ranging from 16 to 18 years old. Laws regarding parental consent can differ by location and situation, impacting areas such as healthcare, education, and legal rights.
