[001] Several co-heir parceners may also claim against several co-heir parceners; here there [002] will be a single action because of the unitary right.]
If an exception lies for the tenant on the thing itself.
[004] If no exception lies for the tenant against the demandant arising either from the [005] person of the demandant or from his own person, and that there is a judicial proceeding [006] is established, by reason of the persons of the judge, the demandant and the [007] tenant, since a proceeding is the threefold act of these three persons,1 we must see [008] whether any exception lies for the tenant arising from the thing claimed. If it is [009] corporeal and an immovable, as land, a tenement or a rent issuing from a tenement,
The demandant must describe the thing he claims with its appurtenances.
[011] the demandant must at the outset describe the thing he claims, that is, what kind of [012] thing it is, that it may be known whether he claims land or a rent [or a tenement] with [013] the appurtenances. Also the quantity, whether it is large or small, [For he must bring [014] a thing certain before the court lest the judgment be illusory or uncertain, for as to [015] an uncertain thing a judgment certain cannot be given, though there may sometimes [016] be a suit for an uncertain thing, the judge or justice, to the extent that it is possible, [017] ought to give a certain judgment.]2 as where he says I claim against such a one so [018] many manors, sometimes with the appurtenances, sometimes without; [or] so [019] many knights fees with the appurtenances, or so many carucates, so many virgates, [020] so many acres, so many selions, or so many librates, so many solidates, [021] so many bovates, according to the variety of tenements and as the matter is stated [022] in writs of right and entry, [provided that the narratio agrees with the writ, for if there [023] is a departure and the declaration does not agree with the writ the demandant loses, [024] because no variance is allowed. A variance sometimes is admitted, however, provided [025] the sense is the same, as where the writ states that he claims two carucates, which [026] are worth ten pounds3 a year and he says I claim ten librates of land; he does not, [027] on that account, withdraw from his writ, because he says what amounts to the same [028] thing; it does not matter whether a thing is done or its equivalent.]
When the demandant has put forward his intentio, the tenant may see whether he holds the whole or not; hence he ought to have the view or what amounts to it.
[030] When the demandant has thus formulated his claim, the tenant ought to consider [031] whether he holds all the land claimed, part of it, or
