MEMORANDUM ORDER
RICHARD W. ROBERTS, District Judge.In his original complaint, plaintiff David Mead brought claims against defendant City First Bank of DC alleging fraud and uncon-scionability regarding loan arrangements between the parties. Mead has filed a motion for leave to amend the complaint to add additional claims and defendants. Among other pending motions are the defendant’s motion for partial summary judgment, the defendant’s motion for an entry of default, the plaintiffs motion for an extension of time to file an answer to the defendant’s counterclaim, and the plaintiffs motion for an CM/ ECF password.
A plaintiff is allowed to amend his complaint after an answer has been filed “only by leave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires.” Fed. R.Civ.P. 15(a)(2). “If the underlying facts or circumstances relied upon by a plaintiff may be a proper subject of relief, he ought to be afforded an opportunity to test his claim on the merits.” Foman v. Davis, 371 U.S. 178, 182, 83 S.Ct. 227, 9 L.Ed.2d 222 (1962). Undue delay, undue prejudice to the defendant, or futility of the proposed amendments are factors that may warrant denying leave to amend. Atchinson v. District of Columbia, 73 F.3d 418, 425 (D.C.Cir.1996). The defendant has the burden of showing why leave to file an amended complaint should not be granted. LaPrade v. Abramson, Civil Action No. 97-10(RWR), 2006 WL 3469532, at *3 (D.D.C. Nov. 29, 2006). The decision to grant or deny leave to amend is committed to the sound discretion of the district court. Foman, 371 U.S. at 182, 83 S.Ct. 227; James Madison Ltd. v. Ludwig, 82 F.3d 1085, 1099 (D.C.Cir.1996).
The proposed first amended complaint asserts seven claims against multiple defendants, including several defendants whose citizenship is not diverse to Mead’s. Mead contends that jurisdiction over his amended complaint is proper under 28 U.S.C. § 1331 because Count Two of the amended complaint alleges a federal question under 12 U.S.C. §§ 3403 and 3417, which provide that a financial institution is liable for damages if it “provide[s] to any Government authority access to or copies of, or information contained in, the financial records of any customer except in accordance with the provisions of [chapter 35 of Title 12 of the United States Code.]”1 City Bank opposes Mead’s motion for leave to amend the complaint, arguing that granting leave to amend the complaint would be futile because federal question jurisdiction is not present in the amended complaint and the presence of non-diverse defendants in the amended complaint defeats diversity jurisdiction under 28 U.S.C. § 1332. In addition, City Bank contends that Mead has failed to state claims in Counts One and Five and that no claims have been stated against proposed defendants CF Bank Corp. and Central Fidelity Corp.
A defendant bears the burden to show futility, while a plaintiff bears the burden to establish the court’s jurisdiction over his case. See Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 103, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998) (“The party invoking federal jurisdiction bears the burden of establishing its existence.”). Although the defendant contends that “[n]o action alleged to have been taken violates” the federal statutes cited in Count Two, “[j]urisdiction ... is not *8defeated ... by the possibility that the aver-ments might fail to state a cause of action on which [a plaintiff] could actually recover. For it is well settled that the failure to state a proper cause of action calls for a judgment on the merits and not for a dismissal for want of jurisdiction.” Bell v. Hood, 327 U.S. 678, 682, 66 S.Ct. 773, 90 L.Ed. 939 (1946). It is not true that the amended complaint does not allege a violation of a federal statute and allege facts in support of that allegation. Thus, City Bank has not shown that there is no basis for this court’s jurisdiction, and has not carried its burden of establishing that granting leave to amend the complaint would be futile.2
Accordingly, it is hereby
ORDERED that the plaintiffs motion for leave to amend the complaint [9] be, and hereby is, GRANTED. Because this order addresses whether the defendant has sustained its burden of showing futility but does not determine whether the plaintiff has carried his burden of establishing the court’s jurisdiction over all of his claims, it is further
ORDERED that Mead shall file by March 26, 2009 a memorandum establishing this court’s subject matter jurisdiction, and all defendants on whom process has been served by that date shall respond by April 6, 2009. It is further
ORDERED that the defendant’s motion for partial summary judgment [4] be, and hereby is, DENIED WITHOUT PREJUDICE in light of the amended complaint. It is further
ORDERED that the defendant’s motion [12] for an entry of default and the plaintiffs motion [16] for an extension of time to file an answer to the defendant’s counterclaim be, and hereby are, DENIED AS MOOT. It is further
ORDERED that the plaintiffs motion [25] for a CM/ECF password be, and hereby is, DENIED WITHOUT PREJUDICE for failure to support his motion with the information required by Local Civil Rule 5.4(b)(2).
. Mead also suggests that federal question jurisdiction may be invoked here under 28 U.S.C. § 2201, Federal Rules of Civil Procedure 54, 57, and 58, and the Seventh Amendment. None of these sources is a federal law under which his civil action arises and they cannot establish this court's jurisdiction under 28 U.S.C. § 1331. Count Six seeking a declaratory judgment regarding state law claims does not establish federal question jurisdiction, and his amended complaint asserts no claim arising out of the Seventh Amendment or the federal rules.
. Similarly, City Bank's challenges to adding particular counts and defendants do not show futility of the entire amendment, and any such defects can be raised and cured by appropriate motion.
