For the Rabbinic provision allowing sons to inherit their mothers' ketubah to apply, the estate must exceed the total value of all ketubot by at least:
Halacha 3 states that if even one dinar does not remain after satisfying all ketubot, the entire estate is divided equally, because otherwise the Rabbinic provision would completely override Scriptural equal division.
Question 2
A man had two wives. One died during his lifetime and one died after him (having taken the required oath). Both left sons. How do the sons of the wife who died after the husband inherit her ketubah?
Halacha 7–8 explain that sons of a wife who died after the husband and took the required oath inherit her ketubah through Torah law of inheritance — not the Rabbinic provision — and their claim takes precedence.
Question 3
A daughter is receiving sustenance from her brothers after her father's death. She then becomes consecrated while still a minor. Who must now support her?
Halacha 15 rules that once a girl becomes consecrated, she loses her right to support from her brothers; therefore her husband becomes obligated to provide her sustenance from the moment of consecration.
Question 4
On his deathbed, a man instructs that his sons should not inherit the money due their mother by virtue of her ketubah. What is the legal outcome?
Halacha 13 rules that such a deathbed instruction has no consequence, because the ketubah obligation took effect at the time of marriage and the husband cannot negate it later.
Question 5
When a father's estate consists only of movable property and is meager (not enough for both sons and daughters), how is it distributed according to the geonim?
Halacha 18 states that since the daughters' right to movable property rests only on a geonic ordinance that placed them equal to the sons — not superior — sons and daughters share the meager movable estate equally.
