MEMORANDUM

Plaintiffs-Appellants argue that because of the prior exclusive jurisdiction doctrine the district court lacked subject matter jurisdiction over this quiet title action (the Quiet Title Action). The prior exclusive jurisdiction doctrine holds that when one court is exercising in rem or quasi in rem jurisdiction over a res, a second court may not assume in rem or quasi in rem jurisdiction over the same res. Chapman v. Deutsche Bank Nat’l Trust Co. (Chapman I), 651 F.3d 1039, 1043-44 (9th Cir.2011) (per curiam).

Approximately three months before Plaintiffs-Appellants filed this Quiet Title Action, Deutsche Bank, a Defendant-Appellant in this case, initiated unlawful de-tainer proceedings (the Unlawful Detainer Action) against Plaintiffs-Appellants in the Reno Justice Court of the State of Nevada.

In an Order filed June 23, 2011, we determined that “if both the Quiet Title Action and the Unlawful Detainer Action are characterized as in rem or quasi in rem, the prior exclusive jurisdiction doctrine requires us to vacate the District Court’s dismissal of the Quiet Title Action.” Id. at 1048 . Finding ourselves unable to determine whether Nevada law characterizes quiet title actions and unlawful detainer actions as proceedings in per-sonam, in rem, or quasi in rem, however, we certified those questions to the Nevada Supreme Court. Id. The Nevada Supreme Court filed an opinion on May 30, 2013, answering our certified questions and concluding that Nevada law characterizes quiet title actions and unlawful detainer actions as proceedings in rem or quasi in rem. Chapman v. Deutsche Bank Nat’l Trust Co. (Chapman II), 129 Nev. Adv. Op. 34 , 302 P.3d 1103 , 2013 WL 2364178, at *5 (Nev. May 30, 2013).

Because the Nevada State Justice Court exercised jurisdiction over the Unlawful Detainer Action before the federal court exercised jurisdiction over the Quiet Title Action, and both actions are in rem or quasi in rem, “the doctrine of prior exclusive jurisdiction fully applies.” Chapman I, 651 F.3d at 1044 (citations and internal quotation marks omitted). Under the doctrine of prior exclusive jurisdiction, “it is legal error for a district court not to remand, dismiss, or stay federal proceedings on account of the state court’s prior exercise of jurisdiction, and any decision on the merits must be vacated.” Id. at 1044 n. 1.

Accordingly, we vacate the district court’s Order dismissing Plaintiffs-Appellants’ complaint for failure to state a claim, because the court lacked jurisdiction to enter it, see State Eng’r v. S. Fork Band of Te-Moak Tribe of W. Shoshone Indians, 339 F.3d 804 , 810-11 (9th Cir.2003), and remand to the district court to determine whether or not parallel state proceedings remain pending. See Weiner v. Shearson, Hammill & Co., Inc., 521 F.2d 817, 822 (9th Cir.1975). If the Unlawful Detainer Action remains pending, the Quiet Title Action should be dismissed for lack of subject matter jurisdiction over the res. Knaefler v. Mack, 680 F.2d 671, 675 (9th Cir.1982). If the state action has terminated, the district court may elect to proceed with the instant action.

VACATED AND REMANDED.
