[MODESTINUS libro secundo regularum. ] §46.1.39.prUt fideiussor aduersus confideiussorem suum agat, danda actio non est.
[MODESTINUS, in the second book of Rules.] An action is not to be granted in order that a surety may sue his co-surety.
ideoque si ex duobus fideiussoribus eiusdem quantitatis cum alter electus a creditore totum exsoluit nec ei cessae sint actiones, alter nec a creditore nec a confideiussore conuenietur.
And therefore, if of two sureties for the same amount, one, having been chosen by the creditor, has paid the whole, and the actions have not been ceded to him, the other will be sued neither by the creditor nor by the co-surety.
