[ULPIANUS libro nono decimo ad edictum. ] §10.2.2.prPer familiae erciscundae actionem diuiditur hereditas, siue ex testamento siue ab intestato, siue ex lege duodecim tabularum siue ex aliqua lege deferatur hereditas uel ex senatus consulto uel etiam constitutione: et generaliter eorum dumtaxat diuidi hereditas potest, quorum peti potest hereditas.
[ULPIAN, on the Edict, book 19] By the action for the division of an inheritance, the inheritance is divided, whether it is devolved by will or on intestacy, or by the Law of the Twelve Tables, or by some other law, or by a senate decree, or even by an imperial constitution; and generally, only the inheritance of those whose inheritance can be claimed by action can be divided.
§10.2.2.1Si quarta ad aliquem ex constitutione diui Pii adrogatum deferatur, quia hic neque heres neque bonorum possessor fit, utile erit familiae erciscundae iudicium necessarium:
If a fourth share is devolved, under the constitution of the deified Pius, upon someone who has been arrogated, since he becomes neither heir nor possessor of the goods, a useful action for the division of the inheritance will be necessary.
§10.2.2.2Item si filii familias militis peculium sit. fortius defendi potest hereditatem effectam per constitutiones, et ideo hoc iudicio locus erit.
Likewise, if there is a peculium of a soldier who is a filius familias, it can be more strongly argued that an inheritance has been created by the constitutions, and therefore there will be room for this action.
§10.2.2.3In familiae erciscundae iudicio unusquisque heredum et rei et actoris partes sustinet.
In the action for the division of an inheritance, each of the heirs sustains the roles of both defendant and plaintiff.
§10.2.2.4Dubitandum autem non est, quin familiae erciscundae iudicium et inter pauciores heredes ex pluribus accipi possit.
Moreover, it is not to be doubted that the action for the division of an inheritance can be accepted even between a smaller number of heirs out of many.
§10.2.2.5In hoc iudicium etsi nomina non ueniunt, tamen, si stipulationes interpositae fuerint de diuisione eorum, ut stetur ei et ut alter alteri mandet actiones procuratoremque eum in suam rem faciat, stabitur diuisioni.
Although claims (nomina) do not enter into this action, nevertheless, if stipulations have been entered into concerning their division, to the effect that it should be adhered to, and that one should mandate his actions to the other and make him a procurator in his own interest, the division shall be adhered to.
