When a person issues a financial claim against a colleague which would require the latter to pay were he to admit [liability]1The qualifications the Rambam mentions here make a distinction between mammon, a financial claim, for which one is liable for a sh'vuat hapikadon and k'nas, a fine, for which one is not liable, as stated in the following halachah. and [the colleague] denies [his obligation] and takes an oath or the plaintiff administers an oath to him and he denies [any obligation]. [If he is lying,] the defendant is liable for an oath concerning a sh'vuat hapikadon.2The term literally means "an oath concerning an entrusted object." Its meaning in a halachic context is explained in this and the subsequent halachot.
If one takes such an oath falsely, he is liable to pay an additional fifth of the principal and bring a guilt offering as stated in Chapter 1, Halachah 9.

[The above applies] even if [the defendant] does not respond Amen.3With regard to other oaths, it is necessary for the person to answer Amen as stated in Chapter 2, Halachah 1. Nevertheless, a sh'vuat hapikadon is a unique instance, as the Rambam continues to explain. For with regard to a sh'vuat hapikadon, one is liable whether he took the oath on his own initiative or another person administered the oath to him and he denied [any obligation], even though he did not respond Amen. For denying the claim after the plaintiff administered the oath is equivalent to responding Amen.4If, however, he remains silent in response to the oath administered by the plaintiff, he is not liable even if he had denied his claim beforehand (Radbaz).

[This does not apply] when [the plaintiff] lodges a claim which if acknowledged by the defendant, i.e., if he would admit that it is true, would not require him to make payment, e.g., he lodged a claim concerning a k'nas.5A fine. In Hilchot Nizkei Mammon 2:8, the Rambam defines a fine as an instance where a person pays more or less than the monetary value of the damage he caused. For a person is not required to pay a k'nas based on his own admission.6See Hilchot Genevah 1:5. See also Chapter 8, Halachot 1-3, for illustrations of this concept. [In such an instance,] if a person denied [an obligation], he is exempt from a sh'vuat hapikadon, but liable for a sh'vuat bitui.7For he is taking a false oath regarding his past activity.

Similarly, if [the plaintiff] lodged a claim concerning landed property, a servant, or a promissory note, and [the defendant] denied [the claim] and took an oath, he is exempt from a sh'vuat hapikadon, but liable for a sh'vuat bitui, for he took a false oath.

Why is one [who took an oath concerning such claims] exempt from [the obligations of a false] sh'vuat hapikadon? Behold, were he to have acknowledged [his obligation], he would have been held liable and [required] to pay what he denied. Because [Leviticus 5:21-22] states: "Concerning an entrusted object, a [financial] deposit, a robbery; he oppressed his colleague, or discovered a lost object." All of this concerns movable property which if he would admit his liability he would have to make financial restitution from his own domain.
This excludes landed property for it is not movable property. For landed property is always revealed before its owner8In contrast to movable property which can be concealed. and is always in their possession.9In contrast to movable property where possession may determine ownership in a situation of doubt, with regard to landed property, a person must display proof of ownership. See also Hilchot To'en V'Nit'an 5:1; Hilchot Gezeilah 8:14; 9:1. [Similarly,] it excludes servants, for an equation is established between servants and landed property.10See Hilchot To'en V'Nit'an, loc. cit. And it excludes promissory notes, for their actual substance is not of financial value.11Instead, they only serve as proof of an obligation (ibid.).

[The above laws apply] whether one took an oath after the plaintiff lodged a claim against him or whether he took it on his own initiative even though a claim was not lodged against him.12Note the contrast to an oath concerning testimony (Chapter 9, Halachah 6-7). The gloss of the Torah Temimah to the prooftext explains that since the verse speaks of "deny his [obligation to] a colleague," he is liable whether his colleague demands an oath of him or not.
What his implied? He took the initiative and said: "Why are you following me? Do I have any money belonging to you? I am taking an oath that I am not in possession of any of your money." Since he denied [an obligation] and took an oath, [he is liable,] even though [the plaintiff] did not lodge a claim against him.

[One is liable] whether he took an oath to the person to whom he owes the money or to his agent who was given power of attorney. For a person's agent is equivalent to his own self.13See Hilchot Shluchim 3:5, 7. See the Lechem Mishneh who emphasizes that the principal must have given the agent power of attorney to require an oath of the defendant. If, however, he merely gave the agent the authority to prosecute the claim, he may not require him to take an oath.

One is not liable for a sh'vuat hapikadon unless he requires him to take an oath in a language that he understands.14For an oath can be taken in any language. Sotah 33a derives this from the exegesis of Leviticus 5:1.

When a person consciously takes a sh'vuat hapikadon, even though he takes a false oath and is warned by witnesses at the time he takes the oath, he is not liable for lashes, but instead must merely bring a guilt offering. For the Torah excluded him from those who are liable for lashes15Neither is one who takes such a false oath liable for lashes for taking a false sh'vuat bitui. and obligated him to bring a guilt offering whether he transgressed willfully or inadvertently, as we explained.16See Chapter 1, Halachah 9, which explains that one is liable for a sacrifice whether he transgressed willingly or inadvertently. As mentioned in the notes to Chapter 1, Halachah 8, one is not liable for lashes either because the transgression does not involve a deed, or because financial compensation must be given and a person is not held liable both for financial restitution and lashes.

If one denied [an obligation] and took an oath [concerning it] four or five times or the plaintiff administered an oath to him four or fives times and he denied each one of them, he is liable for a guilt offering for each individual oath.17Note the contrast to an oath concerning testimony, as stated in Chapter 10, Halachah 18. He is also liable to pay an additional fifth of the principal for each false oath, as stated in Halachah 15. [This applies] whether this took place in a court or outside the court.
[The rationale is that] were he to have admitted his obligation after making his denial, he would be liable to make restitution even though he made the denial in a court. Thus with each denial, he is making himself exempt from payment. Hence, he is liable for each individual oath.

If five different people were lodging claims against him and telling him: "Give us the entrusted article of ours that you have in your possession," and he responds: "[I am taking] an oath that I do not have anything of yours in my possession," [should his oath be false,] he is liable for only one sacrifice.18Since his response included all of them in one statement, it is considered only as one oath.
[If he answers: "I am taking] an oath that I don't have anything of yours, or of yours,... or of yours, in my possession," he is liable for each [statement].19Since he addressed each one individually, each statement is considered as an independent oath.

If his colleague told him: "Give me the entrusted object, [financial] deposit, stolen object, and lost object [of mine], that you have in your possession," and he responds: "[I am taking] an oath that I do not have anything of yours in my possession," [should his oath be false,] he is liable for only one [sacrifice].20Since his response included all of these items in one statement, it is considered only as one oath. Even if the total of all the claims is [merely] a p'rutah, they are all included together and he is liable.21In this instance, were they to have been considered individually, he would be exempt, for since each of the claims are less than a p'rutah, they are not significant individually. Nevertheless, since he included them in one statement, the sum is totaled as one and he is liable.

[If he answers: "I am taking] an oath that I don't have an entrusted object, [financial] deposit, stolen object, and lost object of yours in my possession," he is liable for each [statement].22Since he mentioned each item individually, each statement is considered as an independent oath and it is necessary that each claim concern the worth of a p'rutah.

[If the plaintiff says:] "Give me the wheat, barley, and buckwheat of mine that you have in your possession," and [the defendant responds]: "[I am taking] an oath that I do not have anything of yours in my possession," [should his oath be false,] he is liable for only one [sacrifice].23Although they are different species of grain, since he included them all in one statement, he is liable only once. Even though buckwheat is a subspecies of wheat, since it is mentioned individually, he is liable for it individually (Radbaz). [If he answers: "I am taking] an oath that I don't have any wheat, barley, and buckwheat of yours in my possession," he is liable for each [statement].

If five different people were lodging claims against him and telling him: "Give us the entrusted article, [financial] deposit, stolen object, and lost object [of mine], that you have in your possession," and he responds to one of them: "[I am taking] an oath that I don't have an entrusted object, stolen object, lost object, and [financial] deposit of yours, or of yours,... or of yours in my possession," he is liable for each claim [made] by each individual. Thus he is liable for 20 guilt offerings.24I.e., this combines the principles stated in Halachot 10 and 12.

If [the defendant] claims that he lost an entrusted object or denies [receiving it], he took an oath, and afterwards admitted [that it was in his possession], and then claimed that it was lost, took an oath, and then admitted [that it was in his possession], he must pay the principal and an additional fifth for each oath that he took.25Similarly, he is liable for a guilt offering for each oath as stated in Halachah 9. [This is derived from Leviticus 5:24 which literally translates as] "its fifths,"26It says chamishitav rather than chamishoto. [implying that] the Torah took into account several fifths for [one sum of] principal.
What is implied? The principal was [worth] four [zuz]. One denied [receiving an entrusted article], took an oath, and then admitted [that he possessed it]. Afterwards, he claimed that it was lost, took an oath and then made a second admission, and then claimed that it was lost, took an oath and then made an admission another time. He is required to pay seven [zuz].27This figure can be explained as follows: The principal is four. He must pay an additional three, for each fifth is one fifth of the new total and not one fifth of the original principal (Chapter 11, Halachah 20). He is not, however, required to pay more than one for the second and third oaths, for one is required to pay one fifth of the principal and not a fifth of the fifths (Radbaz). Note, however, Hilchot Gezelah 7:12 which explains that if he already was held liable by a court for the additional fifth, it becomes considered as part of the principal. Similar laws apply in all analogous situations.

A value less than a p'rutah is not considered as financially significant.28This principle is also reflected in Hilchot To'en V'Nit'an 3:1 and Hilchot Sanhedrin 20:11. In Hilchot Shekalim 1:3, the Rambam defines a p'rutah as half a barleycorn of silver. Shiurei Torah defines this as 1/40th of a gram of silver. Hence, if a person lodges a claim against a colleague for less than a p'rutah or for articles worth less than a p'rutah and [the defendant] denied the obligation and took an oath, he is exempt with regard to a sh'vuat hapikadon29For such an oath concerns a financially significant claim and this does not. The Sifra derives this from the exegesis of Leviticus 5:26. and liable for a sh'vuat bitui.30For he took a false oath, as in Halachot 2-3.
