Taking Back Stolen Property in the Mikvah

Question

If I strongly suspect that an individual in my community stole $150 from my wallet while I was in the mikvah, and I am personally convinced that it was him, am I permitted—if he is currently in the mikvah—to check his wallet and, if I find $150 there, take it back?

Answer

It is forbidden to do so. Rather, you must confront the individual directly. If he denies the accusation, you should bring the matter before a Beit Din, presenting whatever proof you have that the money was stolen.

Explanation

There is a Talmudic and halachic principle discussed primarily in Choshen Mishpat known as “עביד איניש דינא לנפשיה” (Avid Inish Dina Lenafshei)—literally, that under certain circumstances a person may take the law into his own hands without first going to court. The rationale behind this concept is practical: it reduces unnecessary litigation and helps maintain social order when the facts are clear and immediate action is warranted.

A classic example is where someone snatches your watch or phone directly from your hand. In such a case, you are not required to go to Beit Din; you may immediately and even forcefully retrieve the very same item that was taken from you.

However, this principle is strictly limited and applies only when all of the following conditions are met:

1. You know with absolute certainty that the individual took the item (e.g., you saw him take it).
2. You are reclaiming the exact item that was taken from you.
3. Retrieving the item does not involve entering the other person’s private domain or property.

If any of these conditions are missing, one may not take matters into his own hands.

In the case described here, none of the necessary conditions are satisfied:

• First, you do not have absolute certainty—only a strong suspicion—that this individual stole the money.
• Second, even if you find $150 in his wallet, there is no way to establish that this is the very same money that was taken from you; it could be his own funds.
• Third, searching or taking money from another person’s wallet is comparable to entering his private property, which is itself prohibited.

For these reasons, reclaiming the money in this manner is forbidden. The proper halachic course of action is confrontation, followed—if necessary—by adjudication in Beit Din.

Practical Note on Installing Cameras in a Mikvah:

In some communities, surveillance cameras are installed in mikvah facilities due to serious and documented safety concerns, including theft, violent incidents, and the protection of children and other vulnerable individuals from predatory behavior. When such systems are used, it must be done in a strictly regulated and transparent manner

Below is example wording used by some facilities. This is not legal advice, but a model script that should be reviewed by both legal counsel and rabbinic authority before use.

Entrance Signage (Where Applicable and Legally Permitted)

Admur Hilchos Gezeila Ugeneiva Halacha 27 “If it becomes known to the owner that the sharecropper (aris) is stealing produce from the orchard, the owner is not permitted—when the time comes to divide the produce—to deduct the stolen amount from the sharecropper’s portion on his own initiative, except through Beit Din. He may not take the law into his own hands and seize from the sharecropper corresponding to what was stolen, because it is prohibited to steal or rob from a thief or robber as compensation for what he stole or robbed. Rather, the owner must summon him to court. If the owner deducts from the sharecropper’s portion without Beit Din authorization, he is considered to be stealing the sharecropper’s rightful share from the remaining produce. Even though the sharecropper has already taken far more than his portion, he did not take it as a division, but rather intended to steal from the owner while his own share remained intact in the remaining produce, since they are partners in all of the produce. Therefore, when the owner forcibly removes the sharecropper’s portion from the remaining produce without his consent, he is robbing him in response to what was stolen. And even though the strict law is indeed as described, one is not permitted to take the law into his own hands without Beit Din. If the owner prevails in court and proves that the sharecropper stole from him, he may collect; if not, he must bear the loss. The same applies to all similar cases.” Halacha 28 “This limitation—that one may not take the law into his own hands—applies only when one is taking something else as compensation for what was taken from him, and not the actual item itself that was stolen. However, to take back the actual object itself that the other stole or robbed from him is permitted; one may take it back against the other’s will. This is not considered theft, but rather saving one’s own property. If the other party does not allow him to retrieve it, he is permitted even to strike him until he allows it, if there is no other way to save it. He is not obligated to go to Beit Din in such a case, because where the actual stolen object is still intact and belongs to him, a person may take the law into his own hands to save it from one who stole it, one who is attempting to steal it, or one who is attempting to damage it—by any means necessary, even force. Even if he would suffer no loss by going to court, he is not required to trouble himself at all. However, one may not go to the thief’s home to steal back his own item, lest he appear to be a thief himself—unless it is impossible to save it in any other way.”; Halacha 29 “All of the above refers to saving one’s property by oneself; however, to save it through a non‑Jew is prohibited in all cases. And all this applies only when one is able to later prove in court that the item is his own if the other party summons him to Beit Din. But if he cannot prove it, then not only is it obvious that he is not permitted to strike the other—for if he strikes him, Beit Din would punish him—but even without striking, his “rescue” is of no legal effect. The only exception is when there are no witnesses to the act of seizing it from the other’s hand. In such a case, his act of saving it is effective, because he will be believed with an oath to say, “I seized my own property,” based on a migo that he could have denied the act altogether and claimed that he seized nothing, since there are no witnesses. However, when there are witnesses, his seizure does not help him at all, except as a form of collateral, and only if the other admits that he owes him some type of debt—and only if that debt did not arise from a loan. For a debt that arises from a loan, it is prohibited in all cases to seize collateral on one’s own authority, as explained in the laws of loans.”; Michaber and Rama 4:1 “A person may take the law into his own hands. If he sees that his own property is in the possession of another who stole it, he may take it from him immediately. If the other resists, he may strike him until he lets it go (if he cannot save it in another way) (Tur). This applies even where there would be no monetary loss if he waited to summon him to court, provided that he can later prove in court that what he took was indeed his. Nevertheless, he has no permission to seize property as collateral for a debt. Gloss (Rema): This is for the reason that will be explained below in siman 97, se’if 6. There are those who say that this restriction applies only to an actual loan debt; but if the other party owes him money not by way of a loan, or if he does not need to seize collateral because the item is already in his possession as a deposit, or if he finds it in the hand of another, it is permitted to seize it (Rivash §396). Others say that we apply the principle of “a person may take the law into his own hands” only with respect to an item that is clearly established as his own—such as where it was stolen from him, or where the other seeks to steal it or damage it—so that he may save his property. But if the other has already become obligated to him due to a past act of theft or from another cause, he may not do so (Mordechai and Nimukei Yosef, chapter HaManiach). And only he himself may take the law into his own hands; it is prohibited to do so through non‑Jews (Terumat HaDeshen §304). However, if one transgressed and did so through non‑Jews, and there was no other way to save his property, then what he did is effective (see Maharik, shoresh 161). There are those who say that it is only called taking the law into one’s own hands when one causes injury to another—such as by striking him—and therefore one may do so only when he can prove that the item is his. But a mere seizure, where one takes property only as security, he may do in any case and then afterwards go down to court with him (Maharik, shoresh 161).” Ben Bag Bag, Bava Bava Kama 27b; Brachos 5b
