2. But in order to create an indebtedness, there must be an actual liability at the time, either to pay then or at a future time. If, for example, a person were to enter and become surety for another, who enters into a rule of reference, he does not thereby become a debtor to the opposite party until the rendition of the judgment on the award. 1 Mass. 134. See Creditor; Debt; Debtor.
