108 Gittin 5/5-7

(5) Rabbi Yochanan ben Gudgodah testified about a deaf woman whose father had married her off that she may leave her marriage with a bill of divorce; and about a female minor Israelite who was married to a Kohen that she may eat terumah, and if she dies her husband inherits her [property]; and about a stolen beam that nwas built into a castle that[ the owner] collects its monetary [value], dut to the enactment of returning[ stolen objects]; and about a stolen sin-offering that was unknown to the public [when offered in the Temple] does provide atonement, due to the enactment [on behalf] of the altar.

(6) The law of sikrikon [violent individuals who acquired fields and houses by use or threat of force, including murder] was not in force in Judea during the time of the war when many Jews were being killed, but from that time on it did apply. How so? If one purchased land from the sikrikon, and then he purchased it from its [rightful] owner, the sale is void; however, [if he purchased it] from the owner and then he purchased it from the sikrikon, the sale is valid. If one purchased [a field] from the husband, and then he purchased it from his wife, the sale is void; but [if he purchased it first] from the wife, and then he purchased it from the husband, the sale is valid. This was the first teaching. But a different court decided that one who purchases [a field] from the sikrikon must pay a quarter to the [rightful] owner. This is when it is not in [the owner's] ability to repurchase [his field]; but if he has the ability to repurchase the field, [the owners] are preferred over anyone else [to repurchase the field]. Rabbi [Yehudah HaNasi] established a court and they decided by consensus that if [a field] remained in the hands of the sikrikon for twelve months, whoever precedes others gains the rights [to purchase the filed] but he must pay a quarter to the [previous] owner.

(7) A deaf person may indicate and be indicated to [with signs between contracting parties]. Ben Beteirah says, "Mouthing [words] and being mouthed to [is effective] for movable property." [With regard to] children at the age of discernment, their purchase and sale is valid with regard to movable property.
