1. When a person sells landed property or movable property to a colleague and someone acquires the property on the purchaser's behalf without the purchaser's knowledge, the option is given to the purchaser. If the purchaser desires to acquire the property, the seller cannot retract. If the purchaser does not desire to acquire the property, the property returns to its original owner.

Therefore, a deed of sale can be written for a seller even when the purchaser is not present. The purchaser, however, is always required to pay the scribe's fee. This applies even if a person sells his field because it is of inferior quality.

2. Similarly, when a Canaanite servant buys or sells property, or whether he gives a present or a present is given to him, the option is given to the servant's owner. If he desires to perpetuate the servant's act, the servant's acts are binding. If the master does not grant his consent, the servant's acts are nullified entirely.

The master may perpetuate or nullify the servant's act with merely a verbal statement. It is not necessary that he confirm his decision with a kinyan.

3. Similarly, when a woman sells or gives a present - whether of property belonging to her husband, property defined as nichsei tzon barzel that she brought him, property that he designated for her in her marriage contract, or property defined as nichsei m'log, whether landed property or movable property - the option is given to her husband. This ruling also applies if she purchases property or if she is given a present. If her husband desires to perpetuate the transfer, it is binding. If he desires to nullify it, it is nullified entirely.

Different rules apply when a husband sells or gives away property to which his wife shares a connection - e.g., land that she brought to him that was recorded in her marriage contract, land that he designated for her in consideration of goods she brought to the marriage, or property that he designated for her in her marriage contract. Even though the purchaser has the woman confirm her husband's deeds with a kinyan, whatever he has done is nullified, because she may rationalize her actions, stating: "I did it only to generate satisfaction for my husband."

4. If the husband sold or gave as a present nichsei m'log, whether landed property or movable property, the option is granted the woman. If she desires to nullify the sale, she may. If, however she confirms her husband's actions, the purchaser acquires the property.

5. The following rule applies when a husband sells movable property that is classified to be nichsei tzon barzel or movable property that he gave his wife from his own property. Although he does not have the right to do so, if he transgresses and sells or gives away such property, it is acquired by the purchasers, and his wife may not expropriate it from them.

Similarly, the husband has the right to sell all of his property, even though it is under lien to his wife's marriage contract. If she is later granted the right to expropriate the property, she will expropriate it. This applies unless she first wrote a disclaimer for the purchaser, and confirmed it with a kinyan.

6. When a woman sells or gives nichsei tzon barzel to her husband, he does not acquire the property. Instead, she may expropriate it from him, as explained in Hilchot Ishut.

When a court sells or purchases property on behalf of orphans - whether landed property or movable property - both the purchase and sale are binding. If, however, it gives the orphans' property away as a present, the gift is of no consequence. The rationale is that a person may not give away something that does not belong to him.

The same principles apply with regard to an orphan's guardian, whether a guardian appointed by the court or one appointed by the orphan's father before his death.

7. When a person sells or gives away property on the Sabbath - and needless to say, on the holidays - although he is punished by stripes, his deeds are binding.

Similarly, when a person enters into a kinyan chalifin on the Sabbath, the kinyan is binding. After the Sabbath, a legal record may be composed and the property transferred.
