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.
It is not necessary to give a formal and written consent to a marriage. In the case of marriage after banns, consent is always presumed in the absence of any notice or expression of dissent by the person or persons, required to give consent. In the case of marriage by Church of England licence, one of the parties must personally swear, on oath, that the consent of the person or persons required to give consent has been obtained, and by solemn declaration before a Superintendent Registrar in the case of a register office marriage.
