minor children

Kids not adults

Minor children are those who have not yet reached the age of legal adulthood, which varies by jurisdiction but is typically eighteen.

The phrase appears almost exclusively in legal, administrative, and formal contexts—wills, custody agreements, insurance policies—where precision matters.

In everyday speech, people simply say kids or children; the modifier minor signals a document concerned with legal rights, responsibilities, or protections that apply specifically to those below the age of majority.
