[PAPINIANUS libro septimo decimo quaestionum. ] §33.2.2.prHominis operae legatae capitis deminutione uel non utendo non amittuntur.
[PAPINIANUS, Questions, book XVII.] The bequeathed services of a slave are not lost by change of status or by non-use.
et quoniam ex operis mercedem percipere legatarius potest, etiam operas eius ipse locare poterit, quas si prohibeat heres capi, tenebitur.
And since the legatee can receive wages from the services, he himself will also be able to lease his services, and if the heir prohibits them from being taken, he will be held liable.
idem est et si seruus se locauerit.
The same is true if the slave has leased himself.
et quia legatarius fructuarius non est, ad heredem suum operarum legatum transmittit: sed seruo usu capto legatum perit.
And because the legatee is not a usufructuary, he transmits the bequest of the services to his own heir; but if the slave is acquired by usucapion, the bequest perishes.
