[If] one finds loan contracts [and] there is a lien on property in them, he should not return [them], since the court would ex-act payment with them. [If] there is no lien on property in them, he should return [them], since the court would not exact payment with them. [These are] the words of R’ Meir. The Sages, however, say: In either case he should not return [them], since the court would exact payment with them.
