[MARCELLUS libro uicensimo digestorum. ] §46.1.38.prSi Stichum aut Pamphilum stipulatus essem, utrum promissor uoluisset, non possum fideiussorem ita accipere Stichum aut Pamphilum, utrum fideiussor uellet, quia futurum esset in eius potestate alium uelle, quam reus uoluisset.
[MARCELLUS, in the twentieth book of the Digests.] If I had stipulated for Stichus or Pamphilus, whichever the promisor wished, I cannot accept a surety for Stichus or Pamphilus in such a way as whichever the surety wished, because it would be within his power to choose a different one from what the principal debtor had wished.
§46.1.38.1A Titio, qui mihi ex testamento sub condicione decem debuit, fideiussorem accepi et ei heres extiti: deinde condicio legati exstitit: quaero, an fideiussor mihi teneatur.
From Titius, who owed me ten under a condition by a will, I accepted a surety and became his heir; then the condition of the legacy was fulfilled: I ask whether the surety is bound to me.
respondit, si ei, a quo tibi erat sub condicione legatum, cum ab eo fideiussorem accepisses, heres exstiteris, non poteris habere fideiussorem obligatum, quia nec reus est, pro quo debeat, sed nec res ulla, quae possit deberi.
He replied: if you have become the heir to the person by whom a legacy was owed to you under a condition, after you had accepted a surety from him, you cannot have the surety bound, because there is neither a principal debtor for whom he should owe, nor any object which could be owed.
