[MARCIANUS libro septimo institutionum. ] §29.7.6.prDiui Seuerus et Antoninus rescripserunt nihil egisse matrem, quae, cum pure liberos suos heredes instituerit, condicionem emancipationis codicillis adiecit, quia neque condicionem heredi instituto codicillis adicere neque substituere directo potest.
[MARCIANUS, in his seventh book of Institutes.] The Divine Severus and Antoninus wrote in a rescript that a mother had done nothing of legal effect, who, although she had appointed her children as heirs unconditionally, added a condition of emancipation by codicils, because one can neither add a condition to an appointed heir by codicils nor substitute an heir directly.
§29.7.6.1Codicillos et plures quis facere potest et ipsius manu neque scribi neque signari necesse est.
Anyone can make even several codicils, and it is not necessary that they be either written or signed by his own hand.
§29.7.6.2Licet in confirmatione codicillorum pater familias adiecerit, ut non alias ualere uelit quam sua manu signatos et subscriptos, tamen ualent facti ab eo codicilli, licet neque ab eo signati neque manu eius scripti fuerint: nam ea quae postea geruntur prioribus derogant.
Even though in the confirmation of codicils a father of a family added that he did not wish them to be valid otherwise than if they were signed and subscribed by his own hand, nevertheless codicils made by him are valid, even if they have been neither signed by him nor written by his hand; for those things which are done later derogate from the prior ones.
§29.7.6.3Codicillos is demum facere potest, qui et testamentum facere potest.
Only he can make codicils who can also make a will.
§29.7.6.4Si post testamentum factum mortuo codicillis quis legauerit licet testamento confirmatis, pro non scripto legatum fit.
If, after a will has been made, anyone bequeathes anything by codicils to a deceased person, even if the codicils are confirmed by the will, the legacy is treated as not written.
