MEMORANDUM OPINION
David and Diane Kahn have moved to dismiss the third-party complaint of Belmont National Bank of Chicago under Rules 12(b)(1) and 12(b)(6), Fed.R.Civ.Pro. In its complaint, Belmont hopes to recover on a guarantee signed by the Kahns, who are alleged to be the principals of C and A Currency Exchange, Inc., in the event that Belmont is liable to Fidelity and Deposit Company of Maryland in the suit which underlies this matter. More specifically, the Kahns, who are Illinois residents, allegedly guaranteed to pay up to $100,000 for checks tendered to Belmont, a national banking association located in Illinois, by C and A in the event that Belmont was unable to collect on the checks. Fidelity’s suit against Belmont presents the argument that Belmont should not have collected on certain checks which Belmont tendered to Fidelity’s insured; Belmont apparently believes that some of these checks came by way of C and A, which also is defending against Fidelity’s suit.
The Kahns initially argue that Belmont’s third-party complaint fails to comply with Rule 8(a). That rule states in part: “A pleading which sets forth a claim for relief, whether an original claim, counterclaim, cross-claim, or third-party claim, shall contain ... a short and plain statement of the grounds upon which the court’s jurisdiction depends, unless the court already has jurisdiction and the claim needs no new grounds of jurisdiction to support it....” Belmont’s complaint does not contain a jurisdictional statement, but Belmont submits that it didn’t need one. In Belmont’s view, the court already has jurisdiction over its claim under the doctrine of ancillary jurisdiction. Complaints brought under the ancillary jurisdiction of the court generally need not meet Rule 8(a)’s jurisdictional statement requirement. See Charles Alan Wright and Arthur R. Miller, 5 Federal Practice and Procedure § 1207 (West 1969).
The Supreme Court has never articulated a precise definition of ancillary jurisdiction or the related concept of pendent jurisdiction. The term “ancillary” is generally used to describe non-federal claims in a controversy which a party asserts after the filing of the original complaint. See Paul M. Bator et al., Hart and Wechsler’s The Federal Courts and the Federal System 1685 n. 1 (Foundation Press 1988). Bel *304 mont’s action against the Kahns apparently is ancillary, as Belmont has not suggested an independent basis for this court’s jurisdiction over it.
Until 1989, many federal courts believed that they had subject-matter jurisdiction over ancillary claims such as that brought by Belmont — essentially, an action for indemnity — where the claim arises out of the same transaction or occurrence. See
Hartford Acc. and Indem. Co. v. Sullivan,
solely on the basis that the Gibbs test has been met. And little more basis than that can be relied on by petitioner here. As in [Owen Equipment & Erection Co. v.] Kroger, [437 U.S. 365 ,98 S.Ct. 2396 ,57 L.Ed.2d 274 (1978)], the relationship between petitioner’s added claims and the original complaint is one of “mere factual similarity,” which is of no consequence since “neither the convenience of the litigants nor considerations of judicial economy can suffice to justify extension of the doctrine of ancillary jurisdiction.”
Finley,
The Kahns suggest that
Finley
prevents this court from exercising jurisdiction over Belmont’s third-party complaint, notwithstanding prior judicial acceptance of the doctrine of ancillary jurisdiction. This court disagrees. Part of the court’s disagreement stems from the obvious distinctions between
Finley
and this case, although it is not enough for the court to say
“Finley
was
Finley
” in order to avoid its consequences. See
Huberman v. Duane Fellows, Inc.,
The second reason for the court’s refusal to dismiss Belmont’s claim for lack of jurisdiction lies within
Finley
itself.
Finley
uses the term “ancillary” in two different ways. While it first describes the class of permissible ancillary claims as “narrow,” two sentences later the Court quotes from
Kroger,
a case involving federal diversity jurisdiction.
Kroger
has a much wider vision of permissible ancillary claims.
Kroger
gives as one example of these “im-pleader by a defendant of a third-party defendant ...”

at 376,
*305 This leaves the Kahns’ argument that Belmont has failed to state a claim against them. Their contention is that, as Belmont’s third-party complaint acknowledges, their liability is contingent on a check being found uncollectible, or perhaps in this case, Belmont being found liable to Fidelity. Neither liability has been established, and thus the Kahns assert that Belmont’s action against them warrants dismissal for being premature. The Kahns, however, present no authority for their position. Belmont’s claims against them are in accord with federal procedure. Rule 14(a) expressly allows a defending party to serve a person not party to the original action “who is or may be liable” to the defending party “for all or part of the plaintiff’s claim” against the defending party. (Emphasis added) The court also has found nothing in Illinois law, the law which allegedly covers the construction of the Kahn’s guarantee, see Third-Party Complaint, Ex. A, which suggests that a beneficiary of a guarantee may not file such an anticipatory action by way of a third-party complaint. The court thus will deny the Kahns’ motion to dismiss under Rule 12(b)(6).
The court denies the Kahns’ motion to dismiss the third-party complaint of Belmont National Bank.
