On Manumission and Proof of Adequate Grounds of Manumission.

The requisition of a certain age of the slave was introduced by the lex Aelia Sentia, by the terms of which law, unless he is thirty years old, a slave cannot on manumission become a citizen of Rome, unless the mode of manumission is by the form of vindicta, preceded by proof of adequate motive before the council.

There is an adequate motive of manumission if, for instance, a natural child or natural brother or sister or foster child of the manumitter’s, or a teacher of the manumitter’s child, or a male slave intended to be employed as an agent in business, or a female slave about to become the manumitter’s wife, is presented to the council for manumission.
