   MEMORANDUM

Jess C. Arndell and Suzanne K. Arndell (collectively, the “Arndells”) appeal the district court’s dismissal of their legal malpractice action. We have jurisdiction under 28 U.S.C. § 1332. We affirm.

The Arndells were not entitled to concealment tolling on their legal malpractice claim under Nev.Rev.Stat. § 11.207(2). We are persuaded that were the Nevada Supreme Court to consider this issue, it would apply the medical malpractice concealment standard from Winn v. Sunrise Hosp. & Med. Ctr., 277 P.3d 458 (Nev. 2012), to legal malpractice concealment. Cf. In re Watts, 298 F.3d 1077 (9th Cir. 2002) (adopting decisions by the California Courts of Appeal interpreting state judgment creditor law after concluding that the California Supreme Court would follow their rationale if presented with the same issue). Legal and medical malpractice claims have similarly structured limitations periods and virtually identical concealment tolling provisions. Compare Nev.Rev.Stat. § 11.207, with Nev.Rev.Stat. § 41A.097.

Under Winn, concealment tolls the statute of limitations when: (1) the defendant intentionally withheld information and (2) that withholding would have hindered a reasonably diligent plaintiff from filing suit. See Winn, 277 P.3d at 464. When the settlement was signed on February 26, 2003, the Arndells knew that Appellees: (1) advocated settling a $11,000,000 claim for $70,000; (2) inappropriately pressured Jess Arndell to settle; (3) admitted they were unprepared for trial; (4) settled the SEA lawsuit for $1,450,000 without authorization; and (5) negotiated the indemnification clause without consent. With this knowledge, a reasonably diligent plaintiff would not have waited for Appellees to provide an accounting and disclose emails before filing a malpractice action. Id.

The Arndells have also failed to demonstrate that they were prejudiced by the district court’s consolidation of their fraud and misrepresentation claims into a legal malpractice claim. See Fed.R.Civ.P. 61. Any fraud or misrepresentation claims they could have asserted based on the allegations in the First Amended Complaint would have been untimely in any event. See Nev.Rev.Stat. § 11.190(3)(d).

AFFIRMED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3.
     
      
      . After considering the parties' responses to our order regarding subject matter jurisdiction, we conclude that Hidden Meadows Company and Jess Arndell Construction Company's assignment of their interests in this litigation to the Arndells was not collusive under 28 U.S.C. § 1359. Accordingly, the district court properly exercised diversity subject matter jurisdiction.
     
      
      . At oral argument, the Arndells maintained that Appellees lied regarding the availability of expert testimony in the SEA lawsuit. This allegation does not appear in the First Amended Complaint and the Arndells have not revealed the contents of this testimony. In any event, withholding of this testimony, even if favorable, is insufficient to establish concealment tolling under the facts of this case.
