MEMORANDUM

GIB, LLC appeals the district court’s grant of Salon Ware, Inc.’s motion to compel arbitration. We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we reverse and remand for further proceedings.

1. The district court erred in holding that GIB waived its right to a trial to determine the enforceability of the written arbitration agreement. GIB challenged the validity of the written agreement in several separate submissions to the district court, starting with its complaint. The district court was required to resolve that challenge pursuant to the procedures established by Section 4 of the Federal Arbitration Act. See 9 U.S.C. § 4 (“If the making of the arbitration agreement ... be in issue, the court shall proceed summarily to the trial thereof. If no jury trial be demanded ..., the court shall hear and determine such issue.”).

2. The district court also erred in holding that GIB was estopped from challenging the enforceability of the written arbitration agreement. In some circumstances, “a nonsignatory may be held to an arbitration clause.” Mundi v. Union Sec. Life Ins. Co., 555 F.3d 1042, 1046 (9th Cir.2009). Here, however, the record does not demonstrate that GIB “knowingly exploit[ed]” or “claim[ed] the benefits of’ the distributorship agreement. Id. at 1045-46 (quoting Comer v. Micor, Inc., 436 F.3d 1098, 1101 (9th Cir.2006)).

3.Finally, the district court erred in compelling arbitration. A court may “decide as a matter of law that the parties did or did not enter into” an arbitration agreement “[ojnly when there is no genuine issue of fact concerning the formation of the agreement.” Three Valleys Mun. Water Dist. v. E.F. Hutton & Co., Inc., 925 F.2d 1136, 1141 (9th Cir.1991) (citation omitted). Here, GIB raised a genuine issue of material fact by submitting a sworn declaration denying that the parties had entered into a written agreement, and email correspondence between the parties suggesting that they had a different, more informal, arrangement. It was also undisputed that GIB never signed the written agreement.

REVERSED AND REMANDED.
