[MARCELLUS libro tertio digestorum. ] §5.2.3.prInofficiosum testamentum dicere hoc est allegare, quare exheredari uel praeteriri non debuerit: quod plerumque accidit, cum falso parentes instimulati liberos suos uel exheredant uel praetereunt.
[MARCELLUS in the third book of the Digests.] To declare a will undutiful is to allege the reason why one ought not to have been disinherited or passed over; and this usually happens when parents, being falsely instigated, either disinherit or pass over their own children.
