This Note examines the role judicial estoppel plays in supporting the U.S. federal bankruptcy regime. Though once considered an obscure doctrine, the use of judicial estoppel to bar pursuit of previously undisclosed claims by former bankrupts has grown apace with burgeoning bankruptcy filings over the last decade. While the doctrine’s application in federal courts has evolved toward a common standard of application, state courts’ application remains idiosyncratic. The Note argues that under the established laws of judgment recognition and in light of federal courts’ sophisticated application of the doctrine, state courts should apply federal judicial estoppel standards to further national uniformity in bankruptcy practice.
