Responsa for Gittin 146:16
תנו רבנן ימים שבינתים בעלה זכאי במציאתה ובמעשה ידיה ובהפרת נדריה ויורשה
Is it not an established maxim that there is no Get after death? — Rabbah replied: We presume that what he said to her was, [This will be a Get] from the time that I am still in the world.<span class="x" onmousemove="('comment',' Which denoted the period immediately preceding his death. R. Judah being of the opinion that the Get comes into force only at the moment before his death, whereas according to R. Jose the Get is in doubtful operation all the time as every moment from the time of delivery may be deemed as the possible moment before his death. Tosaf. suggests a slight change in reading, according to which the rendering would be: '(When he says, " from="" to-day="" if="" i="" die",="" this="" is="" equivalent="" to="" saying)="" the="" time="" that="" am="" in="" next="" world'.'="" according="" rabbah="" dispute="" of="" r.="" judah="" and="" jose="" not="" concerned="" with="" opening="" case="" when="" he="" said="" 'from="" now="" die',="" where="" all="" would="" agree="" get="" becomes="" retrospectively="" valid="" at="" his="" death.="" ');"=""><sup>15</sup></span> Our Rabbis taught: In the days between,<span class="x" onmousemove="('comment',' The giving of the Get and his death.

A. The bill of divorcement was ineffective. First, according to R. Tam and Ri the stipulated condition mentioned above, is to be interpreted to mean that A intended the divorce to become effective an hour before his death. Since on the day of A's death the bill of divorcement was already torn up, no divorce took place. A similar query was sent to me from Acco (Aachen?) and I ruled that no divorce took place. I always advise women who receive such conditional divorces to guard their bills of divorcement carefully till their husbands die. Secondly, even according to Rashi, who believes that the divorce becomes effective immediately upon the delivery of the bill of divorcement, if the husband subsequently dies from his illness, the fact that A was walking thereafter without the support of a cane nullified the bill of divorcement. In any event the advice of a medical authority would be required in order to decide whether or not A died from his first illness; and nowadays we have no medical authorities on whose expert opinion we can definitely rely in such a vital matter.
R. Meir adds: I do not possess the Tosaphot to tractate Gittin, nor the code books from the south (Alfasi and Maimonides). I composed the above with the help of heavenly guide; if you find that the Tosaphot and the codes hold another opinion, my opinion is nullified by theirs; for what does a poor man know, one who dwells in darkness and gloom for three and one half years.
This responsum was sent to Rabbi Asher from the tower of Ensisheim and was placed in his (R. Meir's) novellae in his own handwriting.
