Confirmation of Estate Law and Legal Definition

Confirmation of estate is the conveyance of an estate, or right, that one has in land, to another who has possession of it, or some estate in it, whereby a voidable estate is made sure and unavoidable, or whereby a particular estate is increased and enlarged. [Langdeau v. Hanes, 88 U.S. 521 (U.S. 1875)]

Confirmation may make good a voidable or defeasible estate, but it cannot operate upon or aid an estate which is void in law. As to such an estate, a confirmation only confirms its infirmity.
