Reference for Ketubot 194:3

תנן וגרושה לא תמכור אלא בבית דין בשלמא למאן דאמר לפי שאין אדם רוצה שתתבזה אשתו בבית דין גרושה לא איכפת ליה אלא למאן דאמר משום חינא גרושה נמי בעיא חן

We learned: And a divorced woman may not sell [her former husband's estate] except with the sanction of the court. This makes sense to the one who said, “Because no man wants his wife to suffer the indignity [of appearing] in court”—he does not care about his divorced wife; but according the one who said, “In order to make marriage more attractive,” a divorced woman would also want marriage to be attractive.
