Burial of a Spouse

Q: Is it permissible to use a printed Ketubah or should it be handwritten?
A: There are some who are opposed to a printed Ketubah, but we see that great Rabbis use a printed Ketubah, and they know what they are doing, just as in the case with other documents. Shulchan Aruch, Choshen Mishpat (48:1). There are those who are strict to hand-write the names, the dates and the amounts of money. Shach ibid. (#1). But the basic Halachah is that it is also permissible to print these parts as well. Shulchan Ha-Ezer (Vol. 2, p. 23). And on the contrary, some authorities say that a printed Ketubah is preferable. And there are those who say so in the name of the Vilna Gaon (Halichot Ha-Gra of Ha-Rav Moshe Sternbuch #184 who writes that if it is printed, the witnesses need not read the entire document since it is clear that they are familiar with the contents, which is not necessarily the case if it is hand-written. And Ha-Rav Moshe Feinstein writes that there is absolutely no advantage in a hand-written Ketubah over a printed one. Shut Igrot Moshe, Even Ha-Ezer 1:178. Ha-Rav Nisan Alpert – one of the leading students of Reb Moshe – related why his Rav wrote this Teshuvah. It happened a few times that at a wedding Ha-Rav Feinstein had taken a printed Ketubah and filled it out and Ha-Rav Eliezer Silver then arrived, publically tore up the Ketubah and rewrote it by hand. This was based on the opinion of Rabbi Yehudah in Mishnah Gittin [3:2] that we should hand-write all documents to ensure that we hand-write a Get. Gittin 26a. Although the Shulchan Aruch [ibid.] does not rule this way, Rav Silver was strict like the opinion of Rabbi Yehudah. Rav Feinstein never said a word but wrote a Teshuvah that there is no advantage to be strict like Rabbi Yehudah's positon. Ha-Rav Herschel Schachter related this story and added and we would not have known the background to this Teshuvah if Ha-Rav Alpert had not revealed it).
