[ULPIANUS libro septimo ad Sabinum. ] §29.2.24.prFuit quaestionis, an pro herede gerere uideatur, qui pretium hereditatis omittendae causa capit, et optinuit hunc pro herede quidem non gerere, qui ideo accepit, ne heres sit, in edictum tamen praetoris incidere.
[ULPIANUS in the seventh book on Sabinus.] It was a question whether a person who takes a price for the purpose of omitting an inheritance is considered to act as heir; and it was held that this person indeed does not act as heir, since he accepted it in order not to be the heir, but nevertheless falls under the edict of the praetor.
siue igitur a substituto non heres accepit siue a legitimo, mortis causa accepisse uidetur.
Therefore, whether the non-heir accepted it from a substitute or from an intestate heir, he is deemed to have acquired it mortis causa.
idemque erit et si non accepit, sed promissa sit ei pecunia: nam et stipulando mortis causa capit.
And the same will hold even if he did not receive it, but money was promised to him; for by stipulating also, he acquires mortis causa.
