10 Someone who engages [one of these women] within [the] 90 day [period] -- [the court] excommunicates him. Rema: And some say that he needs to divorce her], and if he is an Israelite [i.e., not a priest] he takes her back after 3 months, while a priest may not take her back (Tur). This applies specifically if he transgressed deliberately, but if he engaged her by accident, he need not divorce her, but [the court] separates them (Mahari"v 73) and some are strict even in the accidental case (Terumat haDeshen 216). And it appears that in the case of a priest who is forbidden to take her back, one should rely on the lenient opinion and not require divorce; but in the case of an Israelite [= non-priest], one should not rely on the lenient position regarding accidents, thus it appears to me. If he divorced her, she is forbidden to live with him in the same mavoi (Riva"sh 360). If the court did not compel him [to divorce her] until after 3 months had passed, even though he engaged her transgressively, they no longer compel him [to divorce her], since once they passed, they passed (Mordekhai ch. Haholetz in the name of the Mahara"m). And if he married [her] and divorced [her], see below in this section subsection 12 the law regarding the ketubah. If he engaged her and fled, we do not excommunicate him. Rema: And we advise him to flee (Tur in the name of Rabbenu Yehiel). There is one who says that this fleeing must be so far that his return would be after three months, but this does not appear to be the case based on the words of other decisors.
