indefeasible

Cannot be undone

Indefeasible describes a right, title, or claim that cannot be annulled, forfeited, or made void.

In legal contexts, an indefeasible title to property is one that cannot be challenged or overturned: The court ruled she held indefeasible rights to the estate.

The word emphasizes absolute security against future defeat or reversal.
