But in my humble opinion, it appears that our teacher, the Rema, and the great later authorities were brief in this matter, and there is no dispute here at all. For they understood that the reasoning of those who permit is because they hold that when there are two witnesses signed on the authorization who testify regarding the witnesses of the get, it is like two people who brought a get, who do not need to say "in my presence it was written and in my presence it was signed," as will be explained. And the "some who disagree," which is the Ribash in siman 318, disagrees with this; and certainly it is so, that he disagrees with this. This is his wording there: That this is neither regarding the validation of the get nor regarding the enactment of the sages, see there. And this is the opinion of the Ramah in the Tur; even though he holds that this is like two who brought it, nevertheless, this is only when the agent delivers the get to the woman in the presence of these witnesses so that it should be a complete matter, for they are the ones testifying on the delivery of the get into the hand of the agent and on the delivery by the agent into the hand of the woman. But when there are other delivery witnesses at the delivery of the agent to the woman, it is "half a matter." And in the Shulchan Aruch itself, they ruled so in section 12, and it will be explained before us with the help of Heaven. And according to this, I say that also the Rashba and the Mordechai, who are those who validate, also do not disagree with this. This is the wording of the Rashba in the Responsa, siman 561: That anyone who brings a get, even though it is not validated, is trusted to say "in my presence it was written and in my presence it was signed," and he does not need witnesses that the husband made him an agent; rather, as long as he brings a get, that is sufficient for him. Know, that if he needed witnesses, he would not need to say "in my presence it was written and in my presence it was signed," for since he has witnesses, it is like it was brought by two, etc. Thus far his words. And it can be said that his intention is when the witnesses are before us, like the opinion of the Ramah, but with witnesses in writing, it is not effective. And the Mordechai is dealing with witnesses in writing, but they were validated with the validation of a beit din, which is the essence of the validation of legal documents, and this is the "henpek" mentioned throughout the Shas; even the Ribash would admit to this, as is explicitly clear from his wording that we brought, for this is "it shall be validated by its signatories" that we learned in the Mishnah. This is the wording of the Mordechai at the beginning of the chapter "HaTikabel": Furthermore, if you have the signature of a beit din and witnesses, etc., why must he say "in my presence it was written and in my presence it was signed"? For even if the husband comes and protests, etc., behold there is the signature of witnesses and a beit din. Thus far his words. And it is from a response of Rabbeinu Tam, of blessed memory, see there. And who would disagree with this?
