Lex Junia Velleia
Lex Junia Velleia A.D. 10, made it possible (which hitherto had not been allowed) to either institute or disinherit certain postumi sui (i.e. descendants who after the making of a will come into the immediate potestas of the testator). Those to whom this lex related were (a) children of the testator born in his lifetime, but after the execution of his will; (b) grandchildren of the testator born after their father's death, but in the lifetime of the testator; (c) grandchildren born before the execution of the grandfather's will, but who become sui heredes by their father's decease after that event (Ulpian, Beg. 22.19; Dig. 28, 2, 29; Gaius, 2.134, and Mr. Poste's note on § 130).
