in the county of Middlesex [the case] of Henry Boiqueinte,1 where Henry lost the  tenement because his father did not make a claim, though2 he was then present, [and  could] have done so, and if he had that would have aided Henry, where the reply  was made to the demandant that a fine was made of the land claimed in the court of  king Henry, grandfather of the lord king, in the thirtieth year of his reign, between  William Reymes, grandfather of William,3 who claimed, and Waleran the father of  the same4 John,5 by which fine the land remained to the same Waleran and his heirs,  and as to that produced a chirograph etc. Afterwards another fine was made of the  same land between Lucy, mother of the aforesaid John, and the same John, and as  to that he produced a chirograph made in the fourth year of king John, and since  neither Henry nor his ancestors put in their claim, John did not wish to answer him  unless the court so wished. To which Henry answered that the first fine and chirograph  could not hurt him because he was then under age. As to the second fine he says  that it ought not to hurt him because he was in the service of the lord king overseas at  Vendome. To this John replied that at the time of both chirographs Henry's father  was alive and sane and present in court when the fines were made, and since he did  not put in his claim he asked judgment whether he ought to answer him. To which  Henry answers that in truth after his father, who [was] a crusader, had gone to the  Holy Land and returned, he was not in possession of his wits and had lost his memory,  so that he knew not how to manage his land and withdrew from it. To which John  answers and says that he was sane and sound and, at the time of the interdict, betook  himself to religion and [in] good memory lived for a long time afterwards in the habit  of religion. And because Henry could not deny this, John withdrew quit.
 When? It is clear that it must be done at once, during the plea [or at the making of  the chirograph] or before judgment if he is present in court, or if in the county or  in the realm within the four seas, nor can he allege ignorance, unless there is some  lawful intervening impediment, nor ought he to be heard thereafter, as is evident,  because he has a term of at least one month, according to the general practice of the  kingdom, within which he can conveniently come after the plea has begun
