The king to the sheriff, greeting. If such a one has made you secure with respect to  the prosecution of his claim, summon etc. twelve free and lawful men of such a  neighbourhood to be before our justices at the first session when they come into those  parts (or at Westminster forthwith or elsewhere on such a day) prepared to recognise  on oath who as patron in time of peace presented the last parson, who has died,  to the church of such a place which is vacant, as it is said, the advowson of which the  same parson says belongs to him. In the meantime let them see that church. And  cause their names to be written down. And summon by good summoners him who  deforces him of that advowson to be there on that day to hear that recognition. And  have there the summoners and this writ. Witness etc.12 <Because the word deforces  is used, some think that the plaintiff indicates thereby that the deforciant is in seisin,  as in the writ of right, but in truth that is not so; he deforces within the meaning of  that term who does not permit a possessor to use his seisin, at all or only with difficulty,3  by presenting, appealing, or impetrating, in accordance with the general rule  that he sufficiently effects a disseisin who does not permit a possessor to use, or to use  conveniently, though he does not expel him completely.> On the first day either  party may essoin himself if he wishes. If both default the plea will be void and the  writ falls. If only the impediant is present, he will withdraw by judgment sine die.  If only the plaintiff is present and the impediant is not, we must then see, first of all,  whether the impediant was summoned or not. If he was, and the summons is attested  by suitable summoners, who when examined attest the summons, let the impediant  be resummoned.4 If he was not summoned, or if the summons is [not] attested, or if  he is present on the first day and alleges that he received no summons, or no proper  summons, let him have another day.5 The summons having been attested, or not  denied, let him be resummoned by this writ.
If the deforciant or impediant does not appear on the first day; how he is to be resummoned.
 The king to the sheriff, greeting. Summon A. by good summoners to be before our  justices at such a place [on such a day] to hear the recognition of the assise of darrein  presentment which B. in our same court before our same justices arraigned against  him, who as patron in time of peace etc. (as above) and to show why he did not appear  before our same justices
