MEMORANDUM ***

The contract and tort claims alleged by Gail Rosier in this diversity action arise out of the attempts by her ex-husband, Jeffrey Strobel, to collect child support and out of statements made by Strobel in New Hampshire and Arizona state court proceedings. The district court dismissed the complaint, finding the contract claims precluded by a New Hampshire state court judgment and the remaining claims premised on statements for which Strobel enjoys immunity. We affirm.

1. Rosier’s contract claims arise from a child support agreement between her and Strobel. Upon Strobel’s motion, a New Hampshire trial court enforced the agreement, ordering Rosier to make funds available for the education of the couple’s son. The court later found Rosier in contempt of that order, and ordered her to pay child support arrearages. Applying New Hampshire law, see Holcombe v. Hosmer, 477 F.3d 1094, 1097 (9th Cir. 2007), the district court correctly found Rosier’s contract claims in this case precluded because they “could have been litigated” in that proceeding. In re Hampers, 166 N.H. 422, 97 A.3d 1106, 1112-13 (2014) (quoting Gray v. Kelly, 161 N.H. 160, 13 A.3d 848, 851 (2010)); see also Osman v. Gagnon, 152 N.H. 359, 876 A.2d 193, 195 (2005).

2. Rosier’s tort claims arise from Stro-bel’s statements to the New Hampshire *371 court during the proceedings described above and his statements to an Arizona court regarding Rosier’s sentencing for an unrelated crime. These statements are privileged from civil liability because they were “made in the course of judicial proceedings” and “pertinent or relevant to the proceedings.” Provencher v. Buzzell-Plourde Assocs., 142 N.H. 848, 711 A.2d 251, 255 (1998); see also Green Acres Tr. v. London, 141 Ariz. 609, 688 P.2d 617, 620-22 (1984). And, because Strobel’s statements were privileged, the district court did not err in denying Rosier leave to amend her complaint to add a claim for sanctions under Federal Rule of Civil Procedure 11 relating to those statements. 1

AFFIRMED.
