[PAULUS libro quinto ad Sabinum. ] §40.7.1.prStatuliber est, qui statutam et destinatam in tempus uel condicionem libertatem habet.
[PAULUS in the fifth book on Sabinus.] A statuliber is one who has freedom established and destined for a certain time or condition.
§40.7.1.1Fiunt autem statuliberi uel condicione expressa uel ui ipsa.
Moreover, persons become statuliberi either by an express condition or by the operation of law itself.
condicione expressa quid est, manifestum est.
What is meant by an express condition is manifest.
ui ipsa, cum creditoris fraudandi causa manumittuntur: nam dum incertum est, an creditor iure suo utatur, interim statuliberi sunt, quoniam fraus cum effectu in lege Aelia Sentia accipitur.
By the operation of law itself is when they are manumitted for the purpose of defrauding a creditor; for as long as it is uncertain whether the creditor will exercise his right, they are in the meantime statuliberi, because fraud is accepted with effect under the Lex Aelia Sentia.
