as he who has any corporeal thing, as land or1 a tenement, from another by some lawful  title or justa causa of acquisition, as by that of gift, sale, exchange and the like,  sometimes with a charter of express warranty and homage, [unless the charter states  that, despite the homage, if the donor is vouched to warranty he is not bound to  warrant nor to escambium, and so agreement defeats law,]2 sometimes without a  charter, because of homage [alone], whether he is of age or a minor, provided that a  minor who is vouched may not answer to the warranty before his full age. And the  same may be said of rights, as wardships, marriages and the like. It is said everyone  who is not forbidden, because one cannot vouch a warrantor in a penal action, where  one is to be convicted of his own delict or injuria and corporal punishment is to be  imposed, since pains ought to fall upon those who cause them not upon others.3
Who may be vouched to warranty.
 We must see who may be vouched to warranty. It is clear that it may be a male or a  female, either a minor or a person of full age, provided that if a minor is vouched the  plea of warranty remains in suspense until his full age, unless the action is so favoured  that his age ought not to be a waited, as in the action of dower. Not only is he who has  given or sold to be vouched to warranty, but their heirs as well, descending ad infinitum,  by reason of the words of the charter, I and my heirs will warrant to such a  one and his heirs etc.4 In that case the heirs are bound to warrant whether they are  near or remote, more remote or most remote. And what is said of heirs may be said of  assigns and of those who stand in the place of heirs, as chief lords, who, so to speak,  succeed their tenants because of the failure of heirs or delict, as in [the portion] on the  escheats of lords.5 And that a warranty ought to extend to assigns, by the modus of the  gift, is proved [in the roll] of the eyre of William of Ralegh in the county of Warwick,  near the end of the roll.6 This is especially so if the first chief lord and first feoffer has  taken the homage and service of the assignee.
