1The writ having thus been impetrated, the sheriff must be called upon at once and  without delay. The duty of the sheriff is to take pledges,2[as above [in the portion]  on novel disseisin.]3 Then, in the presence of the parties, if they wish to be present,  he must choose twelve men, who [ought to view] the common of pasture at once. Let  them see the place in which the common4 is claimed, and also the tenement to which  it is said to be appurtenant. The tenement in which the common is claimed, that is,  its nature and size and its boundaries. They ought to enquire carefully into the kind  of disseisin, that is, whether he is completely expelled or hindered from using conveniently.  Also the season at which common is owed, and for what kind and what  number of beasts, that they may certify the justices thereof when required. They  ought to see the tenement to which the common of pasture is said to be appurtenant  because no one may claim common of pasture as appurtenant to his free tenement  unless he has a free tenement.5 It is called free to distinguish it from villeinage, from  villeins who hold a villeinage, because they have neither an action nor the assise,  only the lord whose free tenement the villeinage is. [And] that it is his free tenement,  not another's, that is, if he holds it [in his own name, not] in another's, as a farmer for  a term or a creditor in gage. They ought to see the place in which the pasture is claimed  because the right to pasture itself cannot be seen. 6It is incongruous to ask how  many acres of common he claims when what ought to be asked is in how many acres  he claims common.
Form of the writ of common of pasture.
 The king to the sheriff, greeting. A. has complained to us that B. wrongfully and  without judgment disseised him of his common of pasture in such a vill which is  appurtenant to his free tenement in that same vill (or in another, such a one). We  therefore order you, if the said A. has made you secure etc. (as above). And in the  meantime cause twelve free men etc. to view that tenement and that pasture, and  summon such a one etc. (as above).7 Having put forward his claim he must support  it according to the form of the writ: 8<First let him confirm the person [of the judge  etc.]>9 show the reason why it is appurtenant to his tenement, as where he says that  the common is appurtenant to his free tenement because he was enfeoffed of the  tenement with common of pasture for so many beasts, [or for some other reason],  as may be drawn from what has been said above of the reasons why common10 is  appurtenant to a tenement.11 He must also show the kind of pasture, whether the  word is used in its broad or narrow sense, that a thing certain may be brought before  the court.12 Also from what tenement
