Ruling 2395. If a girl wishes to get married and she has reached the age of legal responsibility (bulūgh) and is mature (rashīdah) – meaning that she is able to determine what is in her interest – and she is a virgin, and she is not in charge of her life’s affairs, such a girl must obtain the consent of her father or grandfather. In fact, based on obligatory precaution, even if she in charge of her life’s affairs, she must still obtain their consent. The consent of her mother or brother is not necessary.
Ruling 2396. If a girl is not a virgin, or if she is a virgin but her father or paternal grandfather totally prevent her from marrying every individual who is legally (sharʿan) and commonly considered to be appropriate for her, then it is not necessary for her to obtain their consent. Furthermore, if they are not at all prepared to participate in the matter of her getting married, or if they are not competent to give their consent because of insanity or suchlike, then in these cases, their consent is not necessary. Similarly, if it is not possible to get their consent because they are absent or because of some other reason, and if the girl has a great need to get married at that time, the consent of her father or paternal grandfather is not necessary.
