Theses de emptione et venditione

V.
For annual rents can also be sold, as well as actions or obligations, whether they are absolute or conditional.

VI.
A hope can also be sold, as well as the inheritance of a deceased person.

VII.
Although once sold, the seller must nevertheless satisfy the hereditary creditors: since he transfers all rights actively to the buyer of the inheritance, but not passively: however, he is not held liable for the eviction of individual items.

VIII.
Furthermore, buying and selling is contracted by mere consent regarding the thing and the price: whether absolutely, or for a future day, or under a condition.

IX.
If, however, it is agreed that the contract be made in writing, or if a thing which consists of weight, number, or measure is bought by weight, number, or measure: in that case, after the documents have been legitimately completed, or if the thing has been duly weighed, measured, or counted, or if it is bought by species, if it is established regarding its quality—for instance if wine has been tasted—we declare that the buying and selling is finally perfected.
