[POMPONIUS libro uicensimo secundo ad Sabinum. ] §12.6.22.prSed et si me putem tibi aut Titio promississe, cum aut neutrum factum sit aut Titii persona in stipulatione comprehensa non sit, et Titio soluero, repetere a Titio potero.
[POMPONIUS, On Sabinus, Book 22.] But also, if I should think that I promised [to pay] to you or to Titius, whereas either neither of these was done, or the person of Titius was not included in the stipulation, and I pay to Titius, I shall be able to recover from Titius.
§12.6.22.1Cum iter excipere deberem, fundum liberum per errorem tradidi: incerti condicam, ut iter mihi concedatur.
When I ought to have reserved a right of way, but by mistake delivered the estate free [of encumbrance], I shall bring an action for an uncertain thing, so that the right of way may be granted to me.
