Before B RANCH , and L AGOA , Circuit Judges

. BY THE COURT : We issued a jurisdictional question about the district court’s subject matter jurisdiction under 28 U.S.C. § 1332 and, specifically, whether the relevant pleadings sufficiently alleged subject matter jurisdiction. Appellants John Nelson Patrick McEachern and Blue Dealer Services, Inc. filed a motion to confirm an arbitration award, which failed to include any jurisdictional allegations. We are not persuaded by the appellants’ argument that we can look through the ir motion to confirm to a complai nt filed by another party in a separate but related case to establish diversity jurisdiction. See Travaglio v. Am. Express Co. , 735 F.3d 1266, 1268 (11th Cir. 2013) (stating thatthe party invoking diversity jurisdiction must allege the citizenships of th e parties at the time suit is filed in federal court). And we decline to take judicial notice of diversity allegations in a complaint filed in a different case. See Shahar v. Bowers , 120 F.3d 211, 214 (11th Cir. 1997) (characterizing the taking of judicial notice as “a highly limited process”). Further, although the appellants suggest that they w ould amend the motion to confirm pursuant to 28 U.S.C. § 1653 to include jurisdictional allegations

, t he y ha ve not filed a motion to amend or state d what t he y would include in such a motion. When, as here, we cannot determine whether there was, in fact, complete USCA11 Case: 23-13298 Document: 26-2 Date Filed: 05/22/2024 Page: 2 of 323

diversity of citizenship, we remand for proceedings on that issue. See Rolling Greens MHP, L.P. v. Comcast SCH Hol dings L.L.C. , 374 F.3d 1020, 1022

- 23 (11th Cir. 2004) ; Purchasing Power, LLC v. Bluestem Brands, Inc. , 851 F.3d 1218, 1228 (11th Cir. 2017) (“In the end, when the parties do not do their part, the burden falls on the courts to make sure parties satisfy the requirements of diversity jurisdiction.We must be vigilant in forcing parties to meet the unfortunate demands of diversity jurisdiction in the 21st century.”). Accordingly, we REMAND this appeal to the district court for the limited purpose of determin ing the citizenship of the parties and whether diversity jurisdiction existed. See Rolling Greens MHP,
L.P. , 374 F.3d at 1022

, 600 F.2d 15, 16 (5th Cir. 1979)

. If the district court determines that the part ies are completely diverse in citizenship, then it should enter an order to that effect and return the record, as supplemented, to this Court for further proceedings. If the district court determines that complete diversity did not exist, then it should vacate
its rulings and dismiss the action. See Am. Motorists , 600 F.2d at 16. USCA11 Case: 23-13298 Document: 26-2 Date Filed: 05/22/2024 Page: 3 of 3
