Related for Ketubot 125:12

One who rebels against her husband... (the rest is missing in Ehrfurt manuscript, but it likely is referring to Mishnah Ketubot 5:7 where this is discussed). This is the original mishnah. Our rabbis decreed that the court should warn her four (sic!) weeks one after the other once (sic!) a week. (Corrections based on Ehrfurt). More than that, even if her ketubah is 100 maneh, she loses it all—whether she is betrothed, married, waiting for her levir, a menstruant or sick.
