Mishnayos Kesuvos Perek 6 Mishnah 5

With regard to one who marries off his daughter with the terms of the dowry unspecified, he must not give her less than fifty dinars. If the bride’s father pledged to bring her into the marriage bare, by saying that he refuses to give her anything, the husband should not say: When I bring her into my house, I will clothe her with my clothing, but not beforehand. Rather, he must clothe her while she is yet in her father’s house, and she enters the marriage with the clothing in hand. And similarly, with regard to a charity administrator who marries off an orphan girl, he must not give her less than fifty dinars. If there are sufficient resources in the charity fund, the charities provide even more for her, furnishing a dowry and her other needs according to her dignity.
