לְעוֹלָם אוֹמְדִין דַּעַת הַנּוֹתֵן. אִם הָיוּ הַדְּבָרִים מַרְאִין סוֹף דַּעְתּוֹ עוֹשִׂין עַל פִּי הָאֹמֶד אַף עַל פִּי שֶׁלֹּא פֵּרֵשׁ. כֵּיצַד. מִי שֶׁהָלַךְ בְּנוֹ לִמְדִינַת הַיָּם וְשָׁמַע שֶׁמֵּת וְכָתַב כָּל נְכָסָיו לְאַחֵר מַתָּנָה גְּלוּיָה גְּמוּרָה וְאַחַר כָּךְ בָּא בְּנוֹ אֵין מַתְּנָתוֹ קַיֶּמֶת. שֶׁהַדְּבָרִים מוֹכִיחִין שֶׁאִלּוּ יָדַע שֶׁבְּנוֹ קַיָּם לֹא הָיָה נוֹתֵן כָּל נְכָסָיו. לְפִיכָךְ אִם שִׁיֵּר מִנְּכָסָיו כָּל שֶׁהוּא בֵּין קַרְקַע בֵּין בְּמִטַּלְטְלִין מַתְּנָתוֹ קַיֶּמֶת:
Whenever a gift is given, we assess the intent of the giver. If the situation indicates his ultimate intent, we act according to that intent, even if it is not stated explicitly. What is implied? A person's son traveled overseas and the father heard a report that his son had died. The father then signed over all his property as a public and binding gift to a third party, and afterwards his son returned. The gift is not binding, for the situation indicates that if the father had known that his son was alive, he would not have signed over all of his property to the third party. Therefore, if he retained ownership over any of his property - whether landed property or movable property - the gift is binding.
