Doctrine of Ineffective Revocation Law and Legal Definition

Doctrine of Ineffective Revocation is a common law principle of trusts and estates law. It makes a revocation of a former will ineffective if the testator made the revocation through execution of a new will, and that newly executed will is determined invalid. This happens when a testator revokes the earlier on the mistaken belief that the new will is valid. The doctrine undoes only the revocation; it does not always accomplish the testator's intent or validate an otherwise invalid will.

Doctrine of Ineffective Revocation is also called dependent-relative-revocation doctrine; conditional revocation or mistakenly induced revocation
