The 1929 Age of Marriage Act made all marriages void from 10 May 1929, if either partner was under the age of 16. Marriages of minors, i.e. under 21, without consent after banns were valid, unless the banns had been forbidden by parents or guardians openly and publicly in church at the time of publication. A Void Marriage has never come into real existence because of some fundamental legal defect, so there was no marriage to annul.
