[TRYPHONINUS libro secundo disputationum. ] §2.14.46.prPactum inter heredem et legatarium factum, ne ab eo satis accipiatur, cum in semestribus relata est constitutio diui Marci seruari in hoc quoque defuncti uoluntatem, ualidum esse constat.
[TRYPHONINUS, Disputations, book 2] It is well established that an agreement made between an heir and a legatee, to the effect that security should not be accepted from him, is valid, since it is reported in the Semestria that there is a constitution of the divine Marcus stating that the will of the deceased must be preserved in this matter as well.
nec a legatario remissa heredi satisdatio per pactionem ex paenitentia reuocari debet, cum liceat sui iuris persecutionem aut spem futurae perceptionis deteriorem constituere.
Nor should security, once remitted to the heir by the legatee through an agreement, be revoked on account of a change of mind, since it is permissible for one to make the enforcement of one's own right or the hope of future acquisition worse.
