Nedarim 73

Sugya Map: The Mechanics of Hafrat Nedarim

• The Issue: Can a husband delegate the nullification of his wife’s future vows to an agent (apotropos) before he hears them?
• Primary Source: Nedarim 73a.
• Nafqa Mina: Is the requirement of "hearing" (u-shama ishah - Num 30:8) a condition on the act of nullification or the validity of the agent?
• Central Tension: If he can nullify without hearing, why use an agent? If he cannot, how does the agent bypass the "hearing" requirement?

Text Snapshot

• "הכא נמי דאמר ליה לכי שמענא..." (Nedarim 73a): The Gemara posits the husband tells the steward: "When I hear [the vow], then it will be nullified for her."
• Nuance: The Lashon suggests a conditional retroactive activation (me-hashta le-khai shama). The agent isn't nullifying now; he is holding a power of attorney for the moment of the husband's future cognition.

Readings

• Ran (ad loc.): Suggests the husband fears distraction (mitridna) or forgetting. He posits that even if the husband has the power to nullify, he may not want to nullify everything right now—he might prefer some vows to stand. The agent provides a surgical, real-time mechanism.
• Rashba (ad loc.): Critiques the mechanics of agency. He insists that shlihut regarding "hearing" is problematic—shlucho shel adam ke-moto (an agent is like the sender) does not automatically transfer the cognitive state of "hearing." If the husband cannot nullify without hearing, the agent cannot either.

Friction

• Kushya: If the husband is worried about forgetting, why not just nullify all future vows now?
• Terutz: As the Ran notes, nullifying ab initio removes the ability to "change one's mind" (le-hehadar). If he delegates to an agent, he retains the ability to revoke the agency or the instructions. The agent is a hedge against his own forgetfulness, not a substitute for his agency.

Intertext

• Nazir 12b: The Gemara parallels this with the husband's power to nullify vows before they are spoken.
• Shulchan Aruch, YD 234:25: Codifies the debate on whether one can nullify vows before they are made (hafarat nedarim le-haba), reflecting the tension between "hearing" as a prerequisite and "husband's power" as an inherent jurisdiction.

Psak/Practice

The halacha generally follows that a husband may nullify vows before they are spoken, provided he identifies the scope. However, the use of an apotropos remains a highly restricted, theoretical construct in most standard practice, as hafarat nedarim is an intensely personal right of the husband (hafarat ha-ba'al).

Takeaway

Agency in nedarim is not about delegating power, but about managing the cognitive load of a husband's authority. The "hearing" isn't a technical hurdle; it’s the boundary of the husband’s proprietary interest in the vow.
