[ULPIANUS libro quinquagensimo ad edictum. ] §45.1.50.prIn illa stipulatione: 'per te non fieri?' non hoc significatur nihil te facturum, quo minus facere possis, sed curaturum, ut facere possis.
[ULPIANUS, in the fiftieth book on the Edict.] In that stipulation: 'that it shall not be due to you?', it is not meant that you will do nothing by which you are prevented from performing, but rather that you will take care that you are able to perform.
§45.1.50.1Item stipulatione emptae hereditatis: 'quanta pecunia ad te peruenerit doloue malo tuo factum est eritue, quo minus perueniat' nemo dubitabit quin teneatur, qui id egit, ne quid ad se perueniret.
Likewise, in the stipulation of a purchased inheritance: 'whatever money has come to you, or has been or will be brought about by your malice, so that it does not come', no one will doubt that he is held liable who has acted so that nothing should come to him.
