is the warrantor of her dower. While the plea is pending he who holds the two parts  commits felony and is outlawed, before the woman has vouched him to warranty with  respect to the third part, and while those two parts are in the lord king's hand by  reason of his term, a dispute arises between two lords concerning the escheat, and it  is not clear which of them ought to obtain; let the woman's case be put sine die or at a  distant day in suspense until certainty may be had, as [in the roll] of the last eyre of  William of Ralegh in the county of Warwick, near the end of the roll.1 The same, it is  submitted, ought to be done in the cases put above. [If] when several are vouched to  warranty there is error in the name of one or several, the matter must be treated,  since they are, so to speak, a single body, as though there were error in the names of  all, as may be seen in the case of several demandants or several tenants.2
If one vouches a warrantor who is within his potestas, though he prays it he will not have the aid of the court.
 When one vouches to warranty one within his potestas, though he prays aid he will not  have it;3 if he does not produce his warrantor he may well lose. If the warrantor is outside  his potestas, and within the power of the king, no matter where, he will have aid.  But if outside the king's potestas, since the king cannot produce him he will not have  aid, and therefore let the vouchor produce him or lose the thing claimed.4
If the warrantor is within a liberty where the king's writ does not run.
 [If one has a liberty within which the king's writ does not run,5 let the lord be ordered,  by reason of the lordship [of the lord] king6 who granted the liberty, to distrain the  warrantor; if he does not, let him be distrained by his lands outside the liberty to  produce him. If he has no lands outside, then, despite the liberty, let the king interpose  his hand because of his default, that right may not fail.]7 When a warrantor cannot  be produced without aid, let a writ for summoning the warrantor issue in this  form.
The writ if he cannot produce him without aid.
 8The king to the sheriff, greeting. Summon A. by good summoners to be before our  justices etc. on such a day to warrant to B. so much land with the appurtenances in  such a vill, which C. in the same court before the same justices etc. claims as his right  against the aforesaid B. as to which the same
