[MARCIANUS libro quarto institutionum. ] §28.7.14.prCondiciones contra edicta imperatorum aut contra leges aut quae legis uicem obtinent scriptae uel quae contra bonos mores uel derisoriae sunt aut huiusmodi quas praetores improbauerunt pro non scriptis habentur et perinde, ac si condicio hereditati siue legato adiecta non esset, capitur hereditas legatumue.
[MARCIANUS, in the fourth book of the Institutes.] Conditions written contrary to the edicts of the emperors, or contrary to the laws, or contrary to those things which hold the place of law, or which are contrary to good morals, or are ridiculous, or of such a kind as the praetors have disapproved, are treated as not written; and just as if the condition had not been added to the inheritance or the legacy, the inheritance or legacy is acquired.
