There is another kind of guardianship known as fiduciary guardianship, which arises in the following manner. If a parent emancipates a son or daughter, a grandson or granddaughter, or other descendant while under the age of puberty, he becomes their statutory guardian: but if at his death he leaves male children, they become fiduciary guardians of their own sons, or brothers and sisters, or other relatives who had been thus emancipated. But on the decease of a patron who is statutory guardian his children become statutory guardians also; for a son of a deceased person, supposing him not to have been emancipated during his father's lifetime, becomes independent at the latter's death, and does not fall under the power of his brothers, nor, consequently, under their guardianship; whereas a freedman, had he remained a slave, would at his master's death have become the slave of the latter's children. The guardianship, however, is not cast on these persons unless they are of full age, which indeed has been made a general rule in guardianship and curatorship of every kind by our constitution.
