[003] Since the assise of mortdancestor is applicable only within certain degrees of kinship, [004] and lies on the death of certain persons against certain persons, and is not extended [005] beyond them, in order that recourse need not always be had to the right by writ of [006] right on a seisin which can be proved by a witness's own sight and hearing, a writ [007] called the writ of cosinage is provided as a supplement to the assise of mortdancestor, [008] to determine the possession, with respect to everything of which the ancestor died [009] seised as of fee, [not as of right, for here only possession is in question,] in degrees of [010] kinship and with respect to persons to whom the assise does not extend, in order to [011] avoid, to the extent that the time-limit of the assise of mortdancestor permits, the [012] uncertain outcome of the duel and the grand assise by writ of right. And since it [013] ought to take the place of mortdancestor and to be held on an ancestor's seisin, it [014] ought properly to follow in large part the nature of the assise in whose stead it is [015] brought, in the first place, with respect to time, that it not exceed the time-limit [016] or term of the assise; in the second, with respect to persons, that it apply beyond [017] the terms of the assise [but] between the same persons, adults or minors, between [018] whom the assise lies within its limits, not between others, as between kinsmen, as [019] said above, by ascending from a grandfather to a greatgrandfather's greatgrandfather, [020] and beyond if the time limit of the action permits, who may all properly be [021] called ancestors in the manner of an assise of mortdancestor, or descending from a [022] grandson to a greatgrandson's greatgrandson and beyond, provided the time limit [023] is not exceeded, who may all properly be called cousins,1 unless one2 says that all [024] are cousins, ascendants and descendants. Nor ought what some say to be an objection, [025] that by this writ, which opens with the word praecipe, lords of courts lose [026] their court, which, as they say, is contrary to the common liberty3 and may [not] be. [027] But in fact it is not true that demandants, because of the seisin of ancestors, must [028] always resort to the court of their lords, for if several actions lie for a man, he may [029] choose one, whichever he wishes, and sue it. For one may be entitled to an assise of [030] novel disseisin and of mortdancestor, a writ of
