A man tells a woman: 'You are consecrated to me on condition that my father consents.' His father hears about it but remains silent. What is her status?
Halacha 1: The Rambam rules that only active consent validates the condition. Silence means the condition was not fulfilled and she is not consecrated.
Question 2
A man stipulates 'you are consecrated on condition you are free of vows.' The woman has a vow not to eat meat. What happens?
Halacha 6: The three vows that nullify such kiddushin are: not to eat meat, not to drink wine, and not to wear colored ornaments. A vow against meat is explicitly listed.
Question 3
A man stipulates 'you are consecrated on condition you have no physical blemishes.' She has a blemish, but a physician heals it before the wedding. What is her status?
Halacha 9: Unlike vow nullification by a sage (which is retroactive), a physician's healing does not retroactively cure the blemish. The husband is assumed to still be repelled by the fact that she once had it.
Question 4
A man tells a woman: 'You are consecrated to me after 30 days.' Within those 30 days, a second man consecrates her. Who is she consecrated to?
Halacha 11: At the time of the second man's kiddushin she was not yet consecrated, so his kiddushin are fully binding. When the first man's 30 days expire, she is already a married woman, rendering his kiddushin void.
Question 5
A principal tells his agent: 'Consecrate her for me in Jerusalem.' The agent finds her and consecrates her in Hebron. Are the kiddushin valid?
Halacha 21: When a principal specifies a location as part of his instruction, the agent must comply exactly. Consecrating her in a different place constitutes a deviation that nullifies the kiddushin entirely.
