[001] donor presents, the first donee does the same and so does the second donee. The [002] presentation, however, does not belong to them all and the question, therefore, is [003] which of them ought be preferred to the others. It is clear that it is not the first donee, [004] because he never presented and never had seisin; nor could he transfer to another [005] what he did not have. Therefore the gift is void as to the first and second donee. Thus [006] the presentation remains of necessity with the donor, who always remained in possession [007] of the right to present, since the donee transferred it to the other before [008] presentation and before use, and the same may be said of several transferees, ad [009] infinitum.1 Suppose that the second donee wished to vouch a warrantor, the first [010] donee; the voucher would be invalid since the second donee is not in possession, nor [011] can one defend another in his possession unless he is in possession,2 since to warrant [012] is nothing other than to defend the possessor. Nor3 if he warrants de facto and vouches [013] over the first donor, is he bound to warrant him, not only because he [the first donee] [014] does not possess, but also because he cannot vouch over; nor can the second donee [015] have again what he never had and could not have. But suppose that the first donor [016] confirms to the second donee the gift made by the first donee; the gift is still not cured [017] by the confirmation, since it is the gift of another, not that of him who confirms or [018] an ancestor of his, and because the gift is void, neither begun nor completed. If both [019] present, he who confirms and he to whom the confirmation was made, he who confirms [020] will prevail by the assise. But if the second donee presents de facto and, when he [021] is thus in seisin, transfers the advowson to another, who also presents, and thus is [022] in seisin of the presentation, if the church then falls vacant and the first donor presents, [023] as does the last donee, and each then arraigns an assise of darrein presentment, [024] the last seisin must be preferred to the first. Nor is an assise afterwards to be taken [025] upon an assise, but let the first donor, if he wishes, sue by writ of right on the property; [026] as to the possession, he may blame himself for his negligence. [On this matter, [027] see above [in the portion on] gifts.]4 When a charter is produced against the assise, [028] as was said above, if it is completely denied it must be proved by the witnesses named [029] in it and the assise taken in the manner of a jury, unless he against whom it is proffered [030] is within age and unable to answer to it before he reaches full age. The assise [031] must then of necessity be deferred until his full age, but by counsel of the court let [032] provision be made, as was said above, retaining a payment as a precaution.5 If no [033] charter is produced against the minor, let the assise proceed6
