1[If a minor is vouched to warranty with respect to a liberty, whether by himself or  with others, we must first inquire whether the minor's ancestor was seised of that  liberty as of fee on the year and day on which he was alive and dead, to this end, that  he be given or denied a delay.]2 He who holds for life may be vouched to warranty,  and may vouch, as well as he who holds in fee, and similarly he who holds for a term  of years. And that he who holds for a term may vouch, though reason suggests the  contrary, is proved [in the roll] of the eyre of William of Ralegh in the county of  Warwick, [the case] of one Sybil who sought dower, near the end of the roll.3
Sometimes a husband vouches his wife to warranty.
 A husband properly vouches his wife to warranty without aid of the court45<unless  the woman, taken from man's rib, rises over his head and rules her husband,> if she is  not named in the writ [and] it is acknowledged or proved that the husband holds  nothing except in his wife's name,6 though according to some the writ ought rather to  fall. It will be otherwise, as is evident, if gifts have been made [to him by her] before  marriage (it is otherwise during marriage)7 with seisin and use for a time. In that case  the husband vouches his wife in the same way he would any other person, and when  she has warranted and the husband has lost she will be bound to escambium, which is  not so in the first case. Conversely, if a husband makes a gift to his wife before marriage  and the wife is impleaded by herself, without her husband, [she will no more answer  [as to that] without him than as to the rest of her inheritance,] she may, so it seems,  vouch him to warranty, and if she loses he may be bound to escambium, just as is said  of the wife. When husband and wife both plead and sue, the husband being his wife's  attorney, and the tenant then vouches the wife to warranty, she must again appear in  court and appoint her husband (or another) her attorney in the plea of warranty,  because her husband is not attorney in that plea though he is in the principal plea, as  may be seen [in the roll] of the eyre of Martin of Pateshull in the county of York in the  tenth year of king Henry, [the case] of Peter de Malo Lacu and Isabel his wife and  John de Besacre.8 And let the same be done in every plea where the tenant has  vouched a warrantor, let the demandant appoint an attorney de novo, though this is  not true of the tenant.
