the demandant and the minor who warranted the tenant will remain without day,  until the warrantor comes of age, as is proved [in the roll] of the eyre of the abbot of  Reading and Martin of Pateshull in the county of Warwick, [the case] of Giles de  Erdington, who was summoned to warrant William of Norfolk,1 [where] because  Giles's father died seised of that William's service, Giles warranted it to William, and  after [he warranted] the principal plea remained without day against the demandant  until Giles's full age. Thus a minor within age will warrant his feoffee-tenant against  the demandant because of his ancestor's seisin of service which he received from his  feoffee in the year and on the day he died.2 But if the ancestor was not seised in the  year and on the day etc. the minor within age will answer neither to the warranty nor  to the principal plea.
A minor is sometimes vouched to warranty without the production of a charter.
 [In some circumstances a minor may be vouched to warranty and be summoned  without the production of a charter, if being under age he is vouched to warranty by  his tenant by reason of a tenement of which the minor was enfeoffed within age, for  there he will answer in both pleas, the warranty and the principal plea. Thus when a  minor is so vouched to warranty we must enquire whether the tenement by reason of  which he is vouched is a descending inheritance or an acquisition.] And what is said  of service may be said of homage,
By homage taken the lord who took the homage is bound to warrant.3
 for suppose that a tenant has no charter, or though he has, does not have it at hand,  whether the feoffment is recent or ancient, as from the Conquest, a time from which  charters are rarely produced; if homage has been taken and can be proved, the chief  lord will warrant without a charter. If he says that he is not bound to warrant without  a charter, he may thus be answered by the tenant: You are bound to warrant me the  land claimed because I am your man thereof and you have taken my homage therefrom  and are in seisin of my service, and my father and his ancestors were the men of  your ancestors. In proof whereof let him produce sufficient suit, [prepared to deraign]  by word of mouth, or one who is prepared if necessary to deraign by his body. If the  vouchee
