MEMORANDUM **

Donald Bradford Stark appeals from the district court’s decision affirming the bankruptcy court’s grant of summary judgment to Barbara Stark, Elizabeth Page Stark, and Susan Tsapanos (the “Creditors”). The bankruptcy court granted summary judgment to the Creditors in this adversary proceeding, finding that Stark’s debt to the Creditors of $2,065,504 — as evidenced by a default judgment of a California probate court — is nondischargeable under 11 U.S.C. § 523(a)(4) as a debt incurred by fraud or defalcation by a fiduciary. We review de novo the bankruptcy court’s legal conclusions. Higgins v. Vortex Fishing Systems, Inc., 379 F.3d 701, 705 (9th Cir. 2004). We have jurisdiction under 28 U.S.C. § 158(d), and we reverse and remand to the bankruptcy court for further proceedings consistent with this decision.

We decline the Creditors’ invitation to apply the Rooker-Feldman doctrine, which generally prohibits federal courts from reviewing state court judgments. See Rooker v. Fidelity Trust Co., 263 U.S. 413, 44 S.Ct. 149, 68 L.Ed. 362 (1923); District of Columbia Court of Appeals v. Feldman, 460 U.S. 462, 103 S.Ct. 1303, 75 L.Ed.2d 206 (1983). Rooker-Feldman’s application in bankruptcy “is limited by the separate jurisdictional statutes that govern federal bankruptcy law,” and the doctrine thus “has little or no application to bankruptcy proceedings that invoke substantive rights under the Bankruptcy Code or that, by their nature, could arise only in the context of a federal bankruptcy case.” Sasson v. Sokoloff (In re Sasson), 424 F.3d 864, 871 (9th Cir.2005). Bankruptcy courts have the power to “avoid state judgments in core bankruptcy proceedings, may modify judgments, and, of primary importance in this context, may discharge them.” Id. (internal citations omitted).

The district court erred by giving pre-clusive effect to the probate judgment. Because the default judgment awarded the Creditors more than the amount requested in the complaint — which did not specify any amount of damages — the judgment is void under section 580 of the California Code of Civil Procedure. The bankruptcy court was required to apply California’s collateral estoppel principles to the judgment, see Cal-Micro, Inc. v. Cantrell (In re Cantrell), 329 F.3d 1119, 1123 (9th Cir.2003), and a judgment that violates section 580 “is subject to collateral attack at any [*983] time” as a judgment “rendered when the court ... exceeded its jurisdiction in granting relief which the court had no power to grant,” Rochin v. Pat Johnson Manuf. Co., 67 Cal.App.4th 1228, 1239, 79 Cal.Rptr.2d 719 (Ct.App.1998). The probate judgment is therefore void, and a California court would not have afforded it preclusive effect. See Ferraro v. Camarlinghi, 161 Cal.App.4th 509, 539, 75 Cal.Rptr.3d 19 (Ct.App.2008) (“[Wjhere relief is given beyond the scope of that asked for, it is a nullity, and may be attacked collaterally, or its effect avoided under the doctrine that it is not res judicata.” (internal quotation marks omitted)).

California courts use one of two options when faced with a default judgment rendered in violation of section 580. First, a California court reviewing such a judgment may modify the judgment and reduce the award to the amount of damages specifically pleaded in the complaint, rather than vacating the judgment entirely. Elec. Funds Solutions v. Murphy, 134 Cal. App.4th 1161, 1177, 36 Cal.Rptr.3d 663 (Ct.App.2005). Second, a California court may allow the plaintiff to choose to amend the complaint to assert greater damages. Greenup v. Rodman, 42 Cal.3d 822, 830, 231 Cal.Rptr. 220, 726 P.2d 1295 (1986). If the plaintiff does so, all issues are open for re-adjudication, including liability. Id. at 830, 231 Cal.Rptr. 220, 726 P.2d 1295.

Here, the complaint did not specify the amount of damages sought against Stark, and we decline to reduce that amount to zero. Therefore, we reverse the district court’s grant of summary judgment and remand with instructions to allow the Creditors to file an amended complaint. The bankruptcy court should then hold an evidentiary hearing to determine whether Stark owes a debt to the Creditors, how much that debt is, and whether the debt is nondischargeable.

REVERSED and REMANDED.
