…your question concerning Mrs. ... consent to her daughter’s marriage: this must be given in order to be a Bahá’í Marriage. Bahá’u’lláh requires this and makes no provision about a parent changing his or her mind. So they are free to do so. Once the written consent is given and the marriage takes place, the parents have no right to interfere any more.
