申命記 24:3的米示拿參照：Mishnah Gittin

[A scribe] who writes out formulas of bills of divorce must leave blank spaces for the name of the man and the name of the woman and the date. [A scribe who writes] loan documents must leave blank spaces for the name of the lender, the name of the borrower, the amount of money and the date. [A scribe who writes] sale documents must leave blank spaces for the name of the seller, the name of the purchaser, the amount of money, the property and the date; [These spaces must be left blank] because of the “takkanah” (enactment). Rabbi Judah disqualifies all of them. Rabbi Elazar validates all of them valid except divorce documents, as it says, “He writes for her” (Deut 24:1), expressly for her.

There are three gittin which are invalid but if a woman marries [on the strength of one of them] the child is fit: If the husband wrote it with his own hand but there are no witnesses on it. If there are witnesses on it but no date. If it has a date but only one witness. These are three gittin which are invalid but if a woman marries [on the strength of one of them] the child is fit. Rabbi Elazar says even though there are no witnesses on it, as long as he gave it to her in the presence of witnesses it is valid, [and on the strength of it] she may collect her ketubah [even] from mortgaged property, since the witnesses only sign on the get because of tikkun olam.
