[IDEM libro quadragensimo quinto ad Sabinum. ] §46.1.4.prPotest accipi fideiussor eius actionis, quam habiturus sum aduersus eum, pro quo fideiussi, uel mandati uel negotiorum gestorum.
[THE SAME in the forty-fifth book on Sabinus.] A surety can be accepted for that action which I shall have against the person for whom I have become a surety, namely, either the action of mandate or the action for management of affairs.
§46.1.4.1Fideiussor et ipse obligatur et heredem obligatum relinquit, cum rei locum optineat.
A surety is both bound himself and leaves his heir bound, since he occupies the position of the principal debtor.
