[POMPONIUS libro tertio ex Plautio. ] §46.8.16.prSi indebitum procuratori solutum sit, agi statim ex hac stipulatione aduersus procuratorem potest, ut ratum habeat dominus, ut possit dinosci, utrumne domino condici debeat id quod indebitum solutum sit, si is ratum habeat, an uero procuratori condicendum sit, si dominus ratum non habeat.
[POMPONIUS, On Plautius, Book III] If what is not due has been paid to an agent, an action can be brought immediately against the agent on this stipulation so that the principal may ratify it, in order that it can be distinguished whether the return of what was paid when not due should be claimed from the principal, if he ratifies it, or whether indeed the claim should be made against the agent, if the principal does not ratify it.
§46.8.16.1Si procurator fundum petisset et cauisset, uti adsolet, ratam rem dominum habiturum, deinde dominus postea eundem fundum uendidisset eumque emptor peteret, stipulationem ratam rem haberi committi Iulianus scribit.
If an agent had claimed a tract of land and had given security, as is customary, that the principal would ratify the matter, and then the principal afterwards sold the same land and the buyer claimed it, Julian writes that the stipulation for ratification is forfeited.
