(Canon 1587).

      9.  It is fit that the notary, on the other hand, is present at all Acts under pain of nullity and to note down with his own hand or at least to affix his signature [to the aforesaid Acts]  (Canon 1558, $ 1).  Because of the special character of these procedures, however it is necessary for the Ordinary  to dispense from the presence of the notary, though because of a reasonable excuse in the acceptance, will be noted in its own place, of the denunciations and also in the expenditure of the degrees of attention or care expected of the notary in a given situation, as they say, in pursuing and examining the witnesses inducted [into the case].
 

    10.   Minor helpers are to be used for nothing unless it is absolutely necessary; and these are to be chosen, in so far as possible, from the priestly order; always, however, they are to be of proved faithfulness and mature without exception.  But it must be noted that, if, when necessity demands it, they can be nominated to accept certain acts, even if they are non -subjects living in another territory on Ordinary of that territory [ can ] be interrogated (Can. 1570, $ 2 ), observing, of course, all of the cautions treated as above and in Canon 1613.

    12.   The aforementioned oath, the formula for which is to be found in the appendix of this instruction 
(Form A), must be used (by those, obviously, who will use it habitually, once for all; by those, however, who are deputed only for some determined piece of business or case, as often as required (toties quoties), in the presence of the ordinary or his delegate done upon the gospels of god (also by priests) and not otherwise and with the added promise of fulfilling faithfully their duty, to which, however, the excommunicated, mentioned above is not extended. There must be an avoidance, moreover, by those who are set over those involved in this cases, lest anyone be admitted to a knowledge of the matters from helpers, unless in some way a party or an office to be performed by that person necessarily requires a knowledge of these matters.
