Which statement about the requirement for parental consent in marriages is true?

The statement regarding judicial consent being required for minors under 14 is accurate within the context of family law. In many jurisdictions, individuals below the age of 14 are considered too young to marry without additional safeguards, acknowledging their immaturity and the need for protection. As such, the law mandates that a judicial authority grants consent to ensure that the marriage serves the best interests of the minor involved. This requirement reflects the legal system's acknowledgment of the vulnerabilities associated with such a young age and aims to prevent exploitation or coercion.

In contrast to this, failure to obtain parental consent typically does not automatically invalidate a marriage; it may lead to legal consequences or complications but does not nullify the union itself. Moreover, individuals over the age of 21 usually do not require parental consent at all, as they are considered adults with full capacity to make decisions about marriage. Lastly, parental consent is generally not required for individuals aged 18 and older, as they are legally recognized as adults, capable of entering marriage contracts independently. Therefore, the requirement for judicial consent for those under 14 stands as the correct statement in this context.
