If a marriage contract stipulates sustenance above and beyond that in the standard ketubah women can claim the right to inheritance based on that ketuba. But they can only claim property and not movable property.
A new Mishna teaches us that men cannot cheat women out of their rights by drawing up substandard ketubot. Regardless of whether or not the ketuba states otherwise or says nothing:
- she should be redeemed if held captive;
- she should be redeemed and returned to her home if held captive as a kohenet
- she should be given 200 dinars even if promised only 100 dinars
- her medical expenses should be paid and she should be cared for until she is not bedridden if she falls ill
