[IAUOLENUS libro tertio ex Plautio. ] §45.2.2.prCum duo eandem pecuniam aut promiserint aut stipulati sunt, ipso iure et singuli in solidum debentur et singuli debent: ideoque petitione acceptilatione unius tota soluitur obligatio.
[JAVOLENUS in the third book from Plautius.] When two persons have either promised or stipulated for the same sum of money, by operation of law each of them is both owed the whole amount and owes the whole amount; and therefore, by the suit or the release of one, the entire obligation is dissolved.
