minor child

Youth under guardianship

A minor child is a person below the age of legal adulthood, typically under eighteen.

The phrase appears most often in legal contexts—custody agreements, estate planning, insurance policies—where precision matters: The trust provides for any minor children of the deceased.

In everyday speech, simply "child" or "minor" suffices.
