1,542. Meaningless Conditions

Hilchos Ishus 12:8

If a man makes a condition to reduce the baseline amount of the kesubah, or if he writes the appropriate amount of 100 or 200 zuz but she writes that she has already received part of that amount when she really didn’t, then this condition is meaningless. This is because if a man makes a kesubah with a virgin for less than 200 or with another woman for less than 100, then their marital intimacy is considered promiscuity.

Hilchos Ishus 12:9

If a man makes a stipulation after marriage not to inherit his wife’s property, the condition is meaningless. Even though his right to inherit her is a rabbinic enactment, the Sages gave it the force of Torah law. When it comes to inheritance, all conditions one might make are irrelevant even though financial matters are involved because Numbers 27:11 refers to the inheritance laws as chukim (statutes). As far as other aspects of the kesubah go, conditions are binding. For example, if the man made a condition not to supply the woman with food or clothing, or that he would not receive benefit from her property, such a condition is binding.
