To clarify the definitions of certain terms relating to marriage under Federal law to prevent child marriages, and for other purposes.

Child Marriage Prevention Act This bill declares that a state is not required to recognize a marriage conducted in another state if one or both of the individuals in the relationship are not at least 18 years old. For purposes of federal law, a marriage shall only be recognized if it is between two people that are 18 or the age defined by the state, whichever is higher. However, state and federal law must recognize a marriage if it was approved by a judge in a proceeding where the minor was represented by independent counsel.
