A testator may revoke a will at any time.1 The right of revocation may not be renounced.2 Revocation may be express or tacit. Express revocation occurs when a testator executes a new will or adds a codicil or change, thereby revoking a prior will or particular disposition.3 Tacit revocation occurs when a testator disposes of particular property during life, i.e., selling a home or car that had been left to legatees in a will.4
