Quando Quod Ago Non Valet Ut Ago, Valeat Quantum Valere Potest Law and Legal Definition

The maxim quando quod ago non valet ut agam, valeat quantum valere potest means when that which I do is not valid as I do it, let it have as much validity as it can have.

“If a deed cannot operate in the manner intended by the parties, the judges will endeavor to construe it in such a way as that it shall operate in some other manner; it being a maxim quando quod ago, non valet ut ago, valeat quantum valere potest. Upon this principle, it has been determined that a deed which was intended to operate as a lease and release, but could not take effect in that manner, was good as a covenant to stand seised.” [JACKSON v. BLODGET, 16 Johns. 172, 178 (N.Y. Sup. Ct. 1819)].
