Canon 1524. §1 The plaintiff may renounce a trial at any stage or at any grade.
Likewise, both the plaintiff and the respondent may renounce the acts of the process either in whole or only in part.

§2 To renounce the trial of an issue, guardians and administrators of juridical persons must have the advice or the consent of those whose agreement is required to conduct negotiations which exceed the limits of ordinary administration.

§3 To be valid, a renunciation must be in writing, and must be signed either by the party, or by a procurator who has been given a special mandate for this purpose; it must be communicated to the other party, who must accept or at least not oppose it; and it must be admitted by the judge.

§1. In qualibet statu et gradu iudicii potest actor instantiae renuntiare; item tum actor tum pars conventa possunt processus actis renuntiare sive omnibus sive nonnullis tantum.

§2. Tutores et administratores personarum iuridicarum, ut renuntiare possint instantiae, egent consilio vel consensu eorum, quorum concursus requiritur ad ponendos actus, qui ordinariae administrationis fines excedunt.

§3. Renuntiatio, ut valeat, peragenda est scripto, eademque a parte vel ab eius procuratore, speciali tamen mandato munito, debet subscribi, cum altera parte communicari, ab eaque acceptari vel saltem non impugnari, et a iudice admitti.
