2)[line 36]מאנהMI'ANAH (MI'UN)
(a)The Torah gives a father the right to marry off his daughter at any age before she is twelve years old.
(b)If she was divorced or widowed or her father died without marrying her off, the Chachamim gave the girl's mother and/or oldest brother the right to marry her off. In these cases the marriage is only mid'Rabanan and she must be at least ten years old, or at least six years old if she has an understanding of the concept of marriage.
(c)According to the RAMBAM and the RA'AVAD, in the above circumstances, the Chachamim also gave her the right to get married by herself. This marriage is also mid'Rabanan. According to the Rambam, she must be at least ten years old, or at least six years old if she has an understanding of the concept of marriage. According to the Ra'avad, however, her Kidushin is valid even if she has enough sense to guard the object given to her for her Kidushin (and she realizes that it was given to her for Kidushin).
(d)In the instances of marriage mid'Rabanan, before she reaches Halachic puberty and becomes a Na'arah (through the growth of two pubic hairs), she has the option of annulling the marriage through a procedure known as Mi'un (refusal). She says before two witnesses, "I do not want him," and the marriage is annulled retroactively. There is no need for her to receive a Get (a bill of divorce). A girl who is married off by her father cannot annul the marriage through Mi'un. (RAMBAM Hilchos Ishus 4:7-8)
