How do we establish ownership of property? Consider a good number of cases demonstrating practical financial law -- and precedent. Including what happens when one party is considered unreliable with regard to oaths. Note the role of the daughter of R. Hisda (wife of Rava). Plus, the weight of a judge's assessment. Also, cases of no designated heir, where it's surprising that the person who died had specific property in his possession (pearls, silver, silk). Or alternatively, when the person who dies has indeed designated an heir, but there might be confusion about that person's name.
