When a person compels a colleague to sell an article and to take the money for the purchase - even if he hung him until he sold the article - the purchase is binding. This applies with regard to movable property and landed property. We say that since he compelled him, he committed himself to selling. This applies even if the seller did not take the money in the presence of witnesses. Therefore, if the seller issues a protest before he sells and tells two witnesses: "Know that the reason I am selling this and this article - or this and this property - is that I am being compelled against my will," the sale is nullified. Even if the purchaser was in possession of the article or the property for several years, it may be expropriated from him, at which point, the seller returns the money.
The witnesses must know that the seller is selling because of compulsion, and that he is actually being compelled against his will. Any record of a protest that does not contain the statement: "We the witnesses know that so and so the seller acted under compulsion - is not a valid protest.
😰 Compulsion + Consent
A sale made under duress is valid — because the seller mentally accepts reality and decides to sell. However, if the seller issued a moda'ah (protest) beforehand to two witnesses saying 'know that I am selling under compulsion,' the sale is nullified. The witnesses must independently know the duress is real — not just rely on the seller's claim.
When does the above apply? With regard to a person who conducts a sale or who negotiates a compromise. With regard to a gift or a waiver of a debt, if the person issues a protest before giving the gift, the gift is nullified even though the person was not compelled to give the gift. The rationale is that with regard to a gift, the factor that is significant is the expression of the giver's will. Since he does not wholeheartedly desire to transfer ownership, the recipient does not acquire the gift. Waiving a debt is equivalent to giving a gift.
Whether one compels a colleague to sell by hitting him, by hanging him or by threatening to employ a measure against him through gentiles or through Jews, he is considered to have been compelled against his will. An incident occurred with regard to a person who had rented an orchard from a colleague for ten years, and the landlord of the orchard lost the debt contract. After the tenant derived benefit from the orchard for three years,the tenant told the owner: "If you do not sell it to me, I will hide the rental contract and claim that I purchased it." The Sages explained that this is considered to be compulsion. The same principles apply in all similar situations. For this reason, if the landlord issued a claim against the tenant in court and the tenant denied it and claimed that the orchard was his, and afterwards, the landlord issued a protest, and then sold the property to the tenant who denies having rented it, the sale is nullified, for there are witnesses that the landlord was compelled against his will. These are the witnesses in whose presence the tenant denied the rental of the property in court, and they are the witnesses before whom the protest was issued.The same principles apply in all similar situations.
When does the above apply? With regard to a person who forces a colleague to sell. He is considered a chamsan because he compels a colleague to sell his property against his will. When, however, a person steals property - is established as a thief - and afterwards purchases the field that he stole the sale is nullified automatically. The seller does not have to issue a protest, as explained in Hilchot Gezelah.
🎁 Gifts Follow a Different Rule
For gifts and debt-waivers, even a moda'ah issued without proven duress nullifies them — because gifts require full inner consent. For sales, duress is required. Compulsion includes physical force, hanging, threats through gentiles or Jews, and threats of fraudulent litigation — all qualify as coercion.
The witnesses to the protest may themselves sign the deed of sale concerning which the protest was issued to them; their participation is of no consequence. Even if the seller tells them in the presence of the person who is compelling him: "I am selling the property willfully, without compulsion," the protest is still viable. Just as the other person compelled the seller to sell unwillingly, he compelled him to say that he was selling it willingly.
Similarly, if the seller admitted in the presence of witnesses that he received money after he issued a protest, he is not obligated to return anything to the thief. We say that the person compelling him compelled him to make this admission. This statement is not heeded for the witnesses already knew that he was compelled against his will. If, however, the robber counted money out to the seller in the presence of the witnesses, the seller is obligated to return the money when the sale is nullified.
If the witnesses to the sale testified that the seller nullified the protest, the protest is nullified. If the seller tells the witnesses to the protest: "Know that every kinyan in which I engage to negate a protest, and a protest regarding a protest are all nullified. I am engaging in them only because of the factor compelling me, of which you are aware. I do not ever have the intention of transferring my property to the person compelling me," the sale is nullified despite the fact that the seller performed a kinyan to nullify his protest, in the manner we have explained.
📋 Witnesses Can Also Sign the Deed
Witnesses to a moda'ah may also sign the resulting deed of sale without conflict. Even if the seller says 'I sell willingly' in front of the coercer, the moda'ah stands — he was also coerced to say that. If seller admits receiving payment, he need not return it; but if money was counted before witnesses, he must return it when the sale is annulled.
If the witnesses to the sale testified that the seller nullified the protest, the protest is nullified. If the seller tells the witnesses to the protest: "Know that every kinyan in which I engage to negate a protest, and a protest regarding a protest are all nullified. I am engaging in them only because of the factor compelling me, of which you are aware. I do not ever have the intention of transferring my property to the person compelling me," the sale is nullified despite the fact that the seller performed a kinyan to nullify his protest, in the manner we have explained.
🔄 Protest Upon Protest
If the coercer gets the seller to perform a kinyan nullifying the moda'ah, the sale may still be voided if the seller first told the same witnesses: 'any kinyan I perform to nullify this moda'ah is itself under duress' — a pre-protest of the counter-protest. This multi-layered protection shows how seriously Jewish law takes genuine consent.

🎓 Key Principles

😰
Duress + Decision Still Makes a Valid Sale Jewish law holds that even a coerced seller who 'gives in' and accepts the price has made a conscious decision to finalize the transaction. The physical act of sale plus mental acceptance — even under pressure — creates a valid kinyan. The exception is when the seller explicitly protests beforehand.
📋
A Moda'ah Must Be Pre-Sale and Independently Verified For a protest to nullify a sale, it must be issued BEFORE the transaction and the witnesses must independently know the compulsion is real. A moda'ah relying solely on the seller's word is invalid — the witnesses must confirm the duress from their own knowledge.
🎁
Gifts Require Full Wholeheartedness — Sales Do Not A gift given without complete inner desire is void — even a mere protest (without proven duress) suffices to nullify it. Sales are more forgiving: external consent under compulsion is recognized as legally adequate, reflecting different standards for voluntary generosity versus commercial exchange.
🔄
Layers of Protest Can Override Layers of Retraction A seller can pre-protest any future kinyan performed to nullify his original protest. This makes it impossible for a coercer to extract a true consent, no matter how many layers of apparent agreement are obtained — as long as the original witnesses know about the ongoing compulsion.
