Reference for Gittin 1:4

אֶחָד גִּטֵּי נָשִׁים וְאֶחָד שִׁחְרוּרֵי עֲבָדִים, שָׁווּ לַמּוֹלִיךְ וְלַמֵּבִיא. וְזוֹ אַחַד מִן הַדְּרָכִים שֶׁשָּׁווּ גִטֵּי נָשִׁים לְשִׁחְרוּרֵי עֲבָדִים:

Both the gittin of women and the manumissions of bondsmen are alike in respect to taking and bringing, [vis-à-vis the saying of: "Before me, it was written, and before me it was signed"]. And this is one of the ways in which the gittin of women are similar to the manumissions of bondsmen.
