In a prior proceeding, Jorge Quintana (Quintana) moved to vacate American General Home Equity, Inc.’s (AGHE) judgment lien against his property. That motion was adjudicated and denied, explicitly with prejudice, by the Bankruptcy Court for the Northern District of Texas on January 9, 2006. In the subsequent bankruptcy court proceedings that form the basis for this appeal, Quintana renewed his claim that AGHE’s lien should be vacated because it had been extinguished by a prior New York state court ruling; additionally, he claimed that the lien was void because AGHE failed to file a proof of claim. The bankruptcy court correctly denied Quintana’s renewed claim because it was res judicata due to the January 9, 2006 judgment, then currently pending appeal. Matter of West Tex. Mktg. Corp., 12 F.3d 497 (5th Cir. 1994) (holding that a dismissal with prejudice is a decision on the merits); Fidelity Standard Life Ins. Co. v. First Nat’l Bank & Trust Co. of Vidalia, Ga., 510 F.2d 272, 273 (5th Cir. 1975) (holding that a judgment pending appeal is res judicata unless and until reversed on appeal). The bankruptcy court also correctly dismissed Quintana’s second argument because a creditor need not file a proof of claim in order to maintain his lien. 11 U.S.C. § 506(d); Matter of Taylor, 132 F.3d 256, 260-61 (5th Cir. 1998).

For the foregoing reasons, the judgment of the district court is affirmed.

AFFIRMED.
