Midrash for Bava Metzia 55:13

<big><strong>גמ׳</strong></big> תנא שכני אבידה מאי שכני אבידה אילימא שכינים דבעל אבידה אי ידע ליה ליזול ולהדריה נהליה אלא שכני מקום שנמצאת בו אבידה:

If he [the husband] states the identification marks of a bill of divorce, and she does likewise,<span class="x" onmousemove="('comment',' Each claims ownership, the husband maintaining that he lost it before delivering it to his wife, so that she is still married to him, and now he has changed his mind and no longer wishes to divorce her, whilst the wife insists that she lost it after receiving it, so that she is divorced. ');">¹¹</span>
