If one free his slave halfway with a bill of release, the slave does not acquire half of his person, and he is a slave just as he was before. However if he releases half of a slave, because of a monetary payment – e.g., he took money for half his worth with the intent of freeing that half – he acquires (half his freedom). Thus, he is half slave and half free man.
When does the above apply? When the master released half of the slave (with a bill of release) and retained half. If, however, he sold half the slave and gave away the other half after, whether the liberation was through the selling or as a gift likewise whether the sale preceded it or after the release the slave acquires half of his person, and acquires or accepts the other.
Similarly, when a slave is owned by two partners, and one frees his half – whether through money or through a legal document – the slave acquires his half, and he is half slave and half free man.
