    MARK HOWARD ALLENBAUGH,

                       Defendant-Appellee.

                     Appeal from the United States District Court

                   Beverly Reid O’Connell, District Judge, Presiding

Before: KELLY,** CALLAHAN, and BEA, Circuit Judges

          Mary Dureau appeals the district court’s denial of her motion for a default

Howard Allenbaugh. We review the denial of a motion for a default judgment for

abuse of discretion and may affirm on any ground finding support in the record. Eitel

v. McCool, 782 F.2d 1470, 1471 (9th Cir. 1986).

      To state a claim for attorney negligence in California, a plaintiff must plead

the existence of proximate causation: i.e., that but-for the attorney’s negligence, the

plaintiff would have prevailed in a given action. Viner v. Sweet, 30 Cal. 4th 1232,

1241 (2003). In her complaint, Dureau’s allegations of proximate causation were

wholly conclusory. Dureau therefore failed to state a claim on which relief could be

granted, Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009), necessitating the denial of her

motion for a default judgment. DirecTV, Inc. v. Huynh, 503 F.3d 847, 854 (9th Cir.

2007); Chudasama v. Mazda Motor Corp., 123 F.3d 1353, 1370 n.41 (11th Cir.

1997). The district court also did not abuse its discretion when it determined that

Dureau’s substantive claims lack merit. Eitel v. McCool, 782 F.2d at 1471–72.

      Dureau failed on appeal to develop her argument seeking a jury trial and has

therefore waived it. Indep. Towers of Washington v. Washington, 350 F.3d 925, 929

(9th Cir. 2003).

      AFFIRMED.
