[LICINIUS RUFINUS libro quarto regularum. ] §31.0.62.prSi alienus seruus heres institutus fuerit, a domino eius fideicommissum relinqui potest.
[LICINIUS RUFINUS in the fourth book of Rules.] If another person's slave has been appointed heir, a trust can be left to be performed by his master.
sed ita hoc fideicommissum dominus praestare debet, si per seruum factus sit heres: quod si ante, quam iussu eius adiretur hereditas, seruus manumissus fuerit et suo arbitrio adierit hereditatem, dominus id debiturus non est, quia heres factus non est, nec seruus, quia rogatus non est.
But the master is obliged to perform this trust only if he has been made heir through the slave. But if, before the inheritance is entered upon by the master's order, the slave has been manumitted and has entered upon the inheritance of his own free will, the master is not to owe it, because he has not been made heir, nor is the slave, because he was not requested to perform it.
ita que utilis actio hoc casu competit, ut is, ad quem emolumentum hereditatis peruenerit, et fideicommissum praestare compellatur.
Therefore, an equitable action (utilis actio) lies in this case, so that he to whom the benefit of the inheritance has come may also be compelled to perform the trust.
