[IDEM libro quinto decimo ad Sabinum. ] §45.1.19.prSi stipulatio facta fuerit: 'si culpa tua diuortium factum fuerit, dari?', nulla stipulatio est, quia contenti esse debemus poenis legum comprehensis: nisi si et stipulatio tantundem habeat poenae, quanta lege sit comprehensa.
[THE SAME, in the fifteenth book on Sabinus.] If a stipulation is made in these terms: 'If a divorce is brought about through your fault, shall [something] be given?', the stipulation is void, because we ought to be content with the penalties prescribed by the laws; unless the stipulation also contains just as much of a penalty as is prescribed by the law.
