Reference for Maaser Sheni 4:7

הַפּוֹדֶה מַעֲשֵׂר שֵׁנִי וְלֹא קָרָא שֵׁם, רַבִּי יוֹסֵי אוֹמֵר, דַּיּוֹ. רַבִּי יְהוּדָה אוֹמֵר, צָרִיךְ לְפָרֵשׁ. הָיָה מְדַבֵּר עִם הָאִשָּׁה עַל עִסְקֵי גִטָּהּ וְקִדּוּשֶׁיהָ, וְנָתַן לָהּ גִּטָּהּ וְקִדּוּשֶׁיהָ וְלֹא פֵרֵשׁ, רַבִּי יוֹסֵי אוֹמֵר, דַּיּוֹ. רַבִּי יְהוּדָה אוֹמֵר, צָרִיךְ לְפָרֵשׁ:

One who redeems <i>Ma'aser Sheni</i> but does not announce its name - Rabbi Yosi says, this is sufficient. Rabbi Yehuda says, one must articulate it. If he was speaking with a woman about matters of her divorce document or her marriage, and then gave her her divorce document or marriage [money] and did not articulate it, Rabbi Yosi says, this is sufficient. Rabbi Yehuda says, one must state it verbally.
