Paulus, Rules, Book II. Where a slave manumitted by the will of his master is not aware that the latter is dead, and that the heir has entered upon his estate, he cannot execute a will, even though he may already be the father of a family, and his own master; for he who is uncertain as to his own condition cannot make an absolute testamentary disposition of property.

Paulus, Rules, Book II. A slave belonging to the estate can be appointed an heir, provided that he had testamentary capacity with the deceased, even though this may not have been the case so far as the heir appointed by the testator was concerned.

Paulus, Rules, Book II. Where a slave is appointed heir to a portion of an estate, and his co-heir has not yet entered upon the estate, he becomes free and a necessary heir, because he does not receive his freedom from his coheir, but from himself; unless his appointment was made as follows: “When anyone becomes my heir, let Stichus be free and be my heir.”
