Opinion:
MEMORANDUM
Plaintiff appeals the district court's judgment dismissing her 42 U.S.C. § 1983 and Monell claims under the Rooker-Feldman doctrine and remanding her state law claims to the Santa Clara County Superior Court. We have jurisdiction under 28 U.S.C. § 1291, see Laub v. U.S. Dep't of Interior, 342 F.3d 1080, 1085 (9th Cir. 2003), and we vacate the district court's order dismissing Plaintiffs federal claims without leave to amend, remand -with instructions to dismiss those claims with leave to amend, and also reverse the order remanding Plaintiffs state law claims.
We review de novo a district court's dismissal under the Rooker-Feldman doctrine, Kougasian v. TMSL, Inc., 359 F.3d 1136, 1139 (9th Cir. 2004), and its grant of a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), Ebner v. Fresh, Inc., 838 F.3d 958, 962 (9th Cir. 2016). Where the district court denies leave to amend because amendment would be futile, we will affirm only if it is clear upon de novo review that the complaint cannot be saved by any amendment. Leadsinger, Inc. v. BMG Music Publ'g, 512 F.3d 522, 532 (9th Cir. 2008). Amendment would not be futile in this instance.
1. We vacate the district court's dismissal of Plaintiffs § 1983 and Monell claims for lack of subject matter jurisdiction under the Rooker-Feldman doctrine. Where "a federal plaintiff asserts as a legal wrong an allegedly illegal act or omission by an adverse party, Rooker-Feldman does not bar jurisdiction." Noel v. Hall, 341 F.3d 1148, 1164 (9th Cir. 2003). Here, Plaintiffs federal claims were based on Defendants' alleged extrinsic fraud on the Santa Clara County Juvenile Court in connection -with dependency proceedings. "A plaintiff alleging extrinsic fraud on a state court is not alleging a legal error by the state court; rather, he or she is alleging a wrongful act by the adverse party." Kougasian, 359 F.3d at 1140-41. Thus, Rooker-Feldman did not bar jurisdiction over Plaintiffs federal claims.
2. Plaintiff failed to state sufficient facts to allege plausible § 1983 and Monell claims against Defendants. She faded to identify the specific false or fabricated evidence that Defendant Caudillo allegedly submitted to the juvenile court. She also did not allege that Defendant Sandoval personally participated in her children's removal. See Jones v. Williams, 297 F.3d 930, 934 (9th Cir. 2002). And she failed to plead facts plausibly suggesting that Caudillo and Sandoval's actions were a product of official county policy. See Connick v. Thompson, 563 U.S. 51, 60-61, 131 S.Ct. 1350, 179 L.Ed.2d 417 (2011). Lastly, Plaintiff does not have standing to assert any constitutional claims based on the harm that her daughter allegedly suffered as a result of her placement in foster care. See Valley Forge Christian Coll. v. Ams. United for Sep. of Church & State, Inc., 454 U.S. 464, 474, 102 S.Ct. 752, 70 L.Ed.2d 700 (1982). However, because Plaintiffs federal claims may be saved by amendment, we remand to the district court with instructions to dismiss those claims with leave to amend to plead plausible facts in support of her theory of extrinsic fraud.
3. We do not address the Defendants' affirmative defense of collateral es-toppel. "Failure to [raise] an affirmative defense below results in waiver, and the issue cannot be raised for the first time on appeal." Kelson v. City of Springfield, 767 F.2d 651, 657 (9th Cir. 1985). Nevertheless, if on remand to the district court, Defendants are allowed to assert the defense in response to an amended complaint, the district court may decide the issue on a far more developed factual record, including that of the juvenile court proceedings, than the one presently before us. See Kougasian, 359 F.3d at 1143-44.
4. Absolute immunity will not bar a plausible § 1983 claim against Caudillo or Sandoval based on their alleged extrinsic fraud in the state dependency proceedings because social workers "are not entitled to absolute immunity from claims that they fabricated evidence during an investigation or made false statements in a dependency petition affidavit that they signed under penalty of perjury." Beltran v. Santa Clara County, 514 F.3d 906, 908 (9th Cir. 2008) (en banc).
5. Because Rooker-Feldman did not deprive the district court of subject matter jurisdiction over Plaintiff's federal claims, see 28 U.S.C. § 1331, 1343, the court may well have had supplemental jurisdiction over Plaintiffs state law claims. Id. § 1367(a). We thus reverse the district court's order remanding Plaintiffs state law claims to the Santa Clara County Superior Court.
Each party shall bear its own costs on appeal.
VACATED, REVERSED, AND REMANDED with instructions.

. Because Plaintiff did not bring a de facto appeal, "there are no issues with which the issues in her federal claims are 'inextricably intertwined' within the meaning of Rooker-Feldman." Kougasian, 359 F.3d at 1143.
