Mishneh Torah, Marriage 7

Sugya Map: Conditional Kiddushin

• Core Issue: Does a condition on kiddushin function as a present-tense act (kiddushin now) or a future-tense act (kiddushin upon fulfillment)?
• Nafka Mina: Retroactive validity, status if the suitor dies before fulfillment, and the necessity of chalitzah if a yavam is involved.
• Primary Sources: Kiddushin 63a, Mishneh Torah, Marriage 7:1, Even HaEzer 38:8-9.

Text Snapshot

Rambam writes: "If he does not consent, if he remained silent, or if he died before he heard of the matter, she is not consecrated" Mishneh Torah, Marriage 7:1. Note the dikduk: the Rambam’s selection of "remained silent" as a disqualifier for kiddushin conditional on "consent" signals his view that consent must be an active, affirmative act (amirah), not merely the absence of objection (shetiqah).

Readings

• Ra'avad (ad loc): Critiques Rambam, arguing that "consent" is satisfied by silence. For the Ra'avad, the father’s failure to object is the threshold of validity.
• Ohr Sameach (Marriage 7:1:1): Defends Rambam by distinguishing between different types of conditions. He suggests that when the son relies on the father's da'at (intent), the father's later silence cannot be retroactively interpreted as validation if the son has already died, as the da'at of the father must be verifiable while the son is alive to satisfy the condition of the marriage bond.

Friction

Kushya: If the condition is "that my father consents," and the father dies without speaking, why is the kiddushin void? Should we not presume the father would have consented, or that his silence is a neutral state? Terutz: The Rambam maintains that kiddushin requires a specific, established state of being. Silence is ambiguous; in the high-stakes realm of kiddushin (where an error creates an eishes ish), the law demands an explicit, positive act to transform the legal status of the woman.

Psak/Practice

In modern halacha, these complex conditions are almost entirely avoided in kiddushin precisely because of the safek (doubt) they generate. The meta-psak heuristic is chashash ishur—where a condition is ambiguous, we mandate a formal get to dissolve the doubt, even if the condition was never technically met.

Takeaway

Conditional kiddushin is a dangerous legal instrument; the Rambam requires explicit, proactive validation, proving that in marriage, silence is not consent—it is a void.
