Whoever frees his share of a common slave and he has sufficient money to free him completely, should let its price be estimated by a just man and give his partners the price of their shares and manumit the slave

If a person has a share, albeit small, to the ownership of a slave, male or female, and he manumits part of it, the slave will be manumitted as much as this part. If the manumitter is well-to-do enough to afford to pay the share of his partner, he ought to manumit the slave wholly, assessing his partner's market value and giving it to him. If he is not that rich, however, he can manumit the slave partially, as much as his share in his ownership, with the rest remaining in bondage.
