Reference for Bava Kamma 1:3
שׁוּם כֶּסֶף, וְשָׁוֶה כֶסֶף, בִּפְנֵי בֵית דִּין, וְעַל פִּי עֵדִים בְּנֵי חוֹרִין בְּנֵי בְרִית. וְהַנָּשִׁים בִּכְלָל הַנֶּזֶק. וְהַנִּזָּק וְהַמַּזִּיק בַּתַּשְׁלוּמִין:
The estimate [of damage must be made only in] money. [Beth-din estimate the amount of the damage, and that is what he pays him. And if Reuven's cow damaged Shimon's cloak, treading upon it in the domain of the nizak (Shimon) and trampling it, and later the foot of this cow were broken by (being caught in) Shimon's cloak, which is also a bor in the public domain, we do not say that since this (cow) damaged and this (cloak) damaged, the damages cancel each other out, but the two damages are assessed, and whoever damaged his neighbor more (than he was damaged) pays (the difference).] [And when they come to pay damages from the property of orphans, they pay only in land, which is] the equivalent of money [and not in metaltelin, which is money itself. For all movable things are regarded as money. For if they cannot be sold here, they can be sold elsewhere.] [And the assessment and payment of damages must be only] before beth-din, [who are experts, and not before a lay beth-din], and by witnesses who are free-men and "children of the covenant" [to exclude bondsmen and idolators, who are not kasher (acceptable) for testimony concerning damages.] And women are included in (the halachoth of) damages. [Whether she damaged others or they damaged her, the laws of damages are the same for men and for women.] And the nizak and the mazik (share) in payment. [Sometimes the nizak shares with the mazik in the payment of damages. As when the carcass deteriorated in value from the time of death until the time of the judgment, in which instance the loss (through deterioration) of the carcass is incurred by the nizak, whether the (damaging) animal be a tam or a muad. It is found, then, that the mazik does not even pay that half-nezek awarded him by the Torah if the animal were a tam, or the full nezek, if it were a muad — so that the nizak loses, thus "sharing" in payment with the mazik.]
