Mishneh Torah, Marriage 8

Sugya Map

• Issue: The intersection of t’nai (stipulation) and devarim she-ba-lev (internal thoughts) in the formation of kiddushin.
• Nafka Mina: Does an unstated assumption (mistaken premise) invalidate a marriage, or must the condition be explicitly articulated?
• Primary Sources: Kiddushin 48b; Mishneh Torah, Marriage 8.

Text Snapshot

"בכל אלו וכיוצא בהן אינה מקודשת... דברים שבלב אינן דברים" Mishneh Torah, Marriage 8:2. Leshon Nuance: Rambam uses the term devarim she-ba-lev to categorically dismiss internal intent when it diverges from the ma’aseh kiddushin (the act of acquisition) or the t’nai (stipulation).

Readings

• Rambam: Asserts that marital acquisition is a formal, objective act. If the objective reality deviates from the specific t’nai, the kiddushin fail, regardless of subsequent "willingness."
• Ritva (Kiddushin 49b): Notes that even where the woman might be willing to overlook a deficiency, the t’nai creates a legal "barrier" (mechitzah) to the acquisition. It is not just about her desire, but about the integrity of the kinyan (acquisition) itself.

Friction

Kushya: If kiddushin is fundamentally a bilateral agreement, why does a secret intent to waive a condition (e.g., "I know he lied, but I accept him anyway") not function as a retroactive mechilah (forgiveness/waiver)? Terutz: The Rambam posits that kiddushin requires a meeting of defined, public legal frameworks. If the t’nai is the vessel for the kinyan, and the vessel is empty or shattered, there is no "marriage" to waive a defect from. You cannot retroactively validate a kinyan that never legally materialized.

Intertext

• SA, Even HaEzer 38:1: Codifies that secret intent (devarim she-ba-lev) is legally null, mirroring the Rambam's insistence that only explicit language defines the marriage status.

Psak/Practice

The heuristic here is "Formalism over Sentiment." In halachic marriage, subjective "willingness" is irrelevant if the objective criteria of the t’nai remain unfulfilled. Practitioners must ensure that all conditions are explicitly stated in the kinyan to avoid safek kiddushin (doubtful marriage).

Takeaway

In the economy of kiddushin, internal sentiment is currency that the law refuses to exchange; if the stated conditions of the contract aren't met, the transaction is void, regardless of how much the parties "meant it" in their hearts.
