Parental consent refers to the legal permission given by a parent or guardian for a child to participate in certain activities or make specific decisions. This is often required for medical treatments, school trips, or legal agreements involving minors. The purpose of parental consent is to ensure that a responsible adult is involved in decisions that affect the child's well-being. In many jurisdictions, parental consent is necessary for minors under the age of 18 to engage in activities such as medical procedures, enrollment in school programs, or traveling abroad. This requirement helps protect children and ensures that their interests are considered in important matters.
