Canon 1142

1. Before a procurator and advocate undertake their function,

they must present an authentic mandate to the tribunal. 2. To

prevent the extinction of a right, however, the judge can admit a

procurator without the presentation of the mandate provided that

some suitable security is furnished if necessary; the judicial

acts, however, lack all force unless the procurator presents a

mandate within the peremptory time limits set by the judge.
