Reference for Gittin 8:1
הַזּוֹרֵק גֵּט לְאִשְׁתּוֹ וְהִיא בְתוֹךְ בֵּיתָהּ אוֹ בְתוֹךְ חֲצֵרָהּ, הֲרֵי זוֹ מְגֹרֶשֶׁת. זְרָקוֹ לָהּ בְּתוֹךְ בֵּיתוֹ אוֹ בְתוֹךְ חֲצֵרוֹ, אֲפִלּוּ הוּא עִמָּהּ בַּמִּטָּה, אֵינָהּ מְגֹרֶשֶׁת. לְתוֹךְ חֵיקָהּ אוֹ לְתוֹךְ קַלְתָּהּ, הֲרֵי זוֹ מְגֹרָשֶׁת:
If one throws a get to his wife, and she is in her house or in her courtyard, she is divorced, [it being written (Deuteronomy 24:1): "And he shall place it (the get) in her hand." Since it is not written: "And in her hand shall he place it," the implication is: "And he shall place" — anywhere, whether in her courtyard, in her garden, or in her enclosure. This, on condition that she be standing by her house or by her courtyard.] If he threw it to her in his house or in his courtyard — even if it (the get) were with her in the bed, she is not divorced. (If he threw it) into her lap or into her sewing box, she is divorced, [even if she were in his house. For the space of her lap and of her sewing box acquires (objects) for her. For a man (her husband) begrudges her (for purposes of acquisition) neither the space of her lap nor of her sewing box.]
