Cum Certum Est An Et Quantum Debeatur Law and Legal Definition

The maxim cum certum est an et quantum debeatur means when it is certain whether (anything is due) and how much is due. A debt is liquidated when it is rendered certain what is due, and how much is due--cum certum est an et quantum debeatur. [Bartee v. Andrews, 18 Ga. 407 (Ga. 1855)]. For although it may appear that something is due, if it does not also appear how much is due, the debt is not liquidated. [Roberts v. Prior, 20 Ga. 561, 562 (Ga. 1856)].
