different tenements by different rights. If different tenements by different rights,  the demandant, if there is one, must essoin himself against all, specifying the persons,  because there are different rights and different pleas, though the several  tenants are included in the one writ. If there are several demandants in common  and one tenant or several, all the demandants must excuse themselves or come and  sue. But the default of one will not be prejudicial to all the others, only to him who  defaulted, with respect to his portion.1 If the tenants hold in common, or separately  provided they hold as parceners, [and] the demandant, or the several demandants  essoin themselves, it suffices, provided that all do so, if they are essoined against  one and the others named in the writ, [or only against one without mention of the  others, for the reason given above,] for when demandants are excused against one of  several tenants in common, the others cannot proceed to default without him. If an  illness befalls a man on the journey, so that he is incapable of coming, he may be  equally incapable of sending several persons to excuse his absence, and therefore it  suffices if he sends a single person against several who are, so to speak, a single  person because of the unitary right they have. [An essoin is not made to the party,  but to the court,2 as is evident, because one may essoin himself in the absence of his  adversary just as in his presence. And similarly, an essoin may be warranted and  the oath taken in the absence of the adversary. Hence it is evident that it suffices if  the justices are informed3 of his incapability. And therefore if he is incapable of  coming or sending, [whether] against one4 [or] against several does not matter, only  that the justices be apprised of his incapability.] But against several [who do not  hold in common], the tenant, one or several, must essoin himself against each by  name, so that it is clear who, against whom, and with respect to what plea, [as may  be seen in appointing an attorney, who attorns whom, against whom, and in what  plea, [for] if all these are not expressed the attorneyship will not be valid,]5 because  he may be essoined against one of the several and in default against another, as  above,6 according as there is a single plea or several.
Who may essoin himself after the duel waged.
 Who? It is clear that both the champion and the principal lord may be essoined  after the duel has been waged, together and on the same day or successively, as [in  the roll] of
