[IDEM libro primo regularum. ] §50.16.213.prCedere diem' significat incipere deberi pecuniam: 'uenire diem' significat eum diem uenisse, quo pecunia peti possit.
[THE SAME, in the first book of rules.] 'The vesting of a right' means that money begins to be owed; 'the arrival of the day' means that that day has come on which money can be demanded.
ubi pure quis stipulatus fuerit, et cessit et uenit dies: ubi in diem, cessit dies, sed nondum uenit: ubi sub condicione, neque cessit neque uenit dies pendente adhuc condicione. '
Where one has made an unconditional stipulation, the day has both vested and arrived; where for a certain day, the day has vested, but has not yet arrived; where under a condition, the day has neither vested nor arrived while the condition is still pending.
§50.16.213.1Aes alienum' est, quod nos aliis debemus: 'aes suum' est, quod alii nobis debent. '
'Debt' is what we owe to others; 'one's own assets' is what others owe to us.
§50.16.213.2Lata culpa' est nimia neglegentia, id est non intellegere quod omnes intellegunt.
'Gross negligence' is excessive negligence, that is, not to understand what everyone understands.
