Civil law often have a higher age requirement for marriage from the Church law demanded. If one party has not attained the age prescribed civil law, the local Ordinary should be consulted and permission is required before a marriage can be legally carried (cf. right. 1071, § 1, No. 3).

Nevertheless, do not be equated with the actions that people who do not go to church anymore does not mean leaving the Catholic Church. There are two reasons for this norm: first because the purpose of these barriers is to keep the Catholic faith, there is no reason why people who have left the Church should be bound to snag it. Secondly, the Church does not want to restrict people''s right to marry.
