Gittin 2:1-2

Gittin 2:1

Let’s say that a messenger delivers a get from overseas and he states that it was written in his presence but he does not state that it was signed in his presence; or he states that it was signed in his presence but he does not state that it was written in his presence; or he says that it was completely written and half-signed in his presence; or it was half-written and completely signed in his presence. In all of these cases, the get is invalid. If one person says that it was written in his presence and another person says that it was signed in his presence, it is invalid. If two people say it was written in their presence and one of them says that it was signed in his presence, it is invalid, though Rabbi Yehuda declares it valid. If one person says it was written in his presence and two people say that it was signed in their presence, it is valid.

Gittin 2:2

If a get was written by day and signed by day, or written by night and signed by night, or written by night and signed by day, it is valid (because in all of these cases the get was both written and signed on the same Hebrew date). If it was written by day and signed by night, it is invalid (because it was signed on the Hebrew date after the date on which it was written). Rabbi Shimon declares such a get valid because he maintains that any document that was written by day and signed by night is invalid except for gittin used to divorce women.
