OPINION
JANE B. STRANCH, Circuit Judge.Forty-one of Kentucky’s 120 counties, through their county attorneys, brought this putative class-action lawsuit in the United States District Court for the Eastern District of Kentucky against Mortgage Electronic Registration Systems, Inc. (MERS) and its shareholders. The counties allege that MERS and its shareholders have assigned and continue to assign mortgage liens among each other without recording those assignments, in violation of Kentucky law. The district court dismissed the lawsuit on the ground that the counties lacked the power to enforce the statute, either prospectively or retrospectively. In support, the court largely relied on this court’s opinion in Christian Cnty. Clerk ex rel. Kent v. Mortgage Electronic Registration Systems, Inc., 515 Fed.Appx. 451 (6th Cir.2013), which held that county clerks lack a private right of action to pursue similar claims.
The counties now argue that they have the power, as subdivisions of the state, to enforce mandatory provisions of Kentucky’s recording statute through civil litigation. This is a novel argument under Kentucky law, which we do not adopt without support from the Kentucky courts. Moreover, because the counties chose to bring this litigation in federal court and sought certification only after the district court ruled against them, we decline to certify a question to the Kentucky Supreme Court.
*821I. Factual and Procedural Background
The Judicial Panel on Multidistrict Litigation succinctly described the MERS business model:
The MERS system purportedly operates as follows: When a home is purchased, the lender obtains from the borrower a promissory note and a mortgage instrument naming MERS as the mortgagee (as nominee for the lender and its successors and assigns). In the mortgage, the borrower assigns his right, title, and interest in the property to MERS, and the mortgage instrument is then recorded in the local land records with MERS as the named mortgagee. When the promissory note is sold (and possibly resold) in the secondary mortgage market, the MERS database tracks that transfer. As long as the parties involved in the sale are MERS members [as most large financial institutions are], MERS remains the mortgagee of record (thereby avoiding recording and other transfer fees that are otherwise associated with the sale) and continues to act as an agent for the new owner of the promissory note.
In re MERS Litig., 659 F.Supp.2d 1368, 1370 n. 6 (U.S.Jud.Pan.Mult.Lit.2009). This lawsuit alleges that the defendants, through MERS, avoid recording mortgage assignments — and thereby avoid paying the recording fees. The counties argue that the defendants’ actions violate Ky. Rev.Stat. § 382.360(3), which, for a mortgage that has been initially recorded, requires: “When a mortgage is assigned to another person, the assignee shall file the assignment for recording with the county clerk within thirty (30) days of the assignment!.]” The counties argue that, under Kentucky law, the assignment of the promissory note secured by a mortgage transfers the mortgage interest as well. See Christian Cnty. Clerk, 515 Fed.Appx. 451, 455 (6th Cir.2013) and cases cited. They therefore maintain that MERS and its shareholders are required to record each assignment and pay the corresponding fees. The counties brought claims for violation of the recording statute, violation of a criminal statute barring illegal liens (Ky. Rev.Stat. § 434.155), fraud, unjust enrichment, and civil conspiracy. The counties seek an injunction mandating that the defendants record all such assignments in the future, as well as compensatory and punitive damages for the past failure to record and for unpaid fees. (R. at Page ID 556)
II. Discussion
The counties appeal from the dismissal of two of their claims: the claim for violation of the recording statute and the claim for unjust enrichment. The district court interpreted the first claim as arising under Ky.Rev.Stat. § 446.070 — Kentucky’s negligence per se statute — despite the fact that the counties did not invoke § 446.070 in their complaint and, in response to the motion to dismiss, maintained that they were not bringing such a claim. The district court correctly determined that the reasoning of Christian County Clerk, 515 Fed.Appx. 451, would bar counties from bringing claims for unjust enrichment and claims under § 446.070. As described below, however, the counties presented a separate argument that they are empowered to independently seek enforcement of mandatory provisions of the recording statute. Because the Kentucky courts have yet to recognize such a power, we do not find it appropriate for us, as a federal court, to do so now.
A. Ky.Rev.Stat. § 446.070
The district court analyzed the counties’ claim as seeking a private right of action— which may be brought only pursuant to *822the negligence per se statute, § 446.070. See Christian Cnty. Clerk, 515 Fed.Appx. at 456. Section 446.070 “creates a private right of action in a person damaged by another person’s violation of any statute that is penal in nature and provides no civil remedy, if the person damaged is within the class of persons the statute intended to be protected.” Hargis v. Baize, 168 S.W.3d 36, 40 (Ky:2005).
In Christian Cnty. Clerk, 515 Fed.Appx. at 456-58, this court held that county clerks could not pursue a recording-statute claim under § 446.070 because they were not within the class of persons that the Kentucky General Assembly sought to protect with the recording statutes. “Considering the overall statutory scheme, Kentucky authorities appear to recognize three categories of protected persons: (1) existing lienholders and lenders who record their security interests in the land to give notice of their secured status; (2) prospective lienholders and purchasers; and (3) property owners and borrowers whose loans have been satisfied.” Id. at 456-57 (citations omitted). The court rejected the clerks’ arguments that their role in administering the system and right to use recording fees manifested an intent to protect them through the recording statute. Id. at 457-58. As correctly noted by the district court, this reasoning would also bar the counties from pursuing a recording-statute claim under the provisions of § 446.070, if they had brought such a claim.
B. Unjust Enrichment
In Christian Cnty. Clerk, we further rejected the clerks’ claims for unjust enrichment because “the benefits that the Clerks purport Defendants have derived from recording .assignments in MERS’s name, such as lien priority and the ability to release satisfied mortgages, would be derived from Kentucky law, not from the Clerks themselves.” 515 Fed.Appx. at 459-60. The counties in the present case allege that they expend resources to maintain recording systems that accrue to the defendants’ benefit, and they provide no reasoning to distinguish their resources from those provided by the county clerks. These arguments mirror the arguments made by the clerks in Christian County Clerk, and the counties do not provide a meaningful argument to distinguish their role in administering Kentucky recording statutes from the clerk’s role. Because, in both cases, the benefits that accrued to the Defendants derived from state law, the reasoning of Christian County Clerk bars an unjust enrichment claim by the counties.
C. The Counties’ New Theory
The counties now argue that Kentucky law empowers them to seek enforcement of a statute in which the county has an interest. Understanding their position requires some background on the legal structure of county government in Kentucky. The Kentucky constitution recognizes counties as subdivisions of the state and establishes several elected offices. See, e.g. Ky. Const. §§ 99, 144. Counties are governed by fiscal courts, which are composed of the county judge/executive and either three commissioners or three to eight justices of the peace. Ky. Const. § 144. The judge/executive, when acting separately from the fiscal court, holds the executive and administrative powers of the county, and the fiscal court exercises the legislative powers of the county. Ky. Const. § 125; Ky.Rev.Stat. §§ 67.710, 67.080. The fiscal court may not exercise executive authority, except as specifically assigned by statute. Ky.Rev.Stat. § 67.080(3). The county attorney is also a constitutionally established office. Ky. *823Const. § 99. A county attorney is responsible for serving as counsel for the fiscal court and “shall institute, defend, and conduct all civil actions in which the county or consolidated local government is interested before any of the courts of the Commonwealth.” Ky.Rev.Stat. § 69.210(1).
The counties analogize the roles of the county attorneys to other constitutional officers that act on behalf of the commonwealth, particularly the attorney general, and seek analogous authority to enforce laws that affect the interests of counties. The Attorney General, exercising his common-law powers, may institute such suits in any venue. Ky.Rev.Stat. § 15.020 (mandating that the Attorney General “exercise all common law duties and authorities” pertaining to the office except where otherwise provided by statute); Commonwealth ex rel. Conway v. Thompson, 300 S.W.3d 152, 172-74 (Ky.2009). Furthermore, in each judicial circuit (the trial-level jurisdiction in Kentucky), the commonwealth’s attorney is empowered to bring and defend litigation on behalf of the commonwealth — in courts within that circuit. Ky.Rev.Stat. § 69.010 (“[T]he Commonwealth’s attorney shall ... attend to all civil cases and proceedings in which the Commonwealth is interested in the Circuit Courts of his judicial, circuit.”); Goose v. Commonwealth ex rel. Dummit, 305 Ky. 644, 205 S.W.2d 326 (1947) (relying on this statutory authority to empower a Commonwealth’s attorney to pursue'an injunction that was not explicitly authorized or available to private parties).1
The counties are staking out a novel legal theory — and such legal innovations are better addressed by Kentucky courts. “[Fjederal courts sitting in a diversity case are in ‘a particularly poor position ... to endorse a fundamental policy innovation.’ ” Combs v. Int’l Ins. Co., 354 F.3d 568, 577-78 (6th Cir.2004) (quoting Dayton v. Peck, Stow & Wilcox Co. (Pexto), 739 F.2d 690, 694 (1st Cir.1984)) (alteration omitted). Therefore, “‘[w]hen given a choice between an interpretation of [state] law which reasonably restricts liability, and one which greatly expands liability, we should choose the narrower and more reasonable path.’ ” Id. at 577 (quoting Todd v. Societe Bic, S.A., 21 F.3d 1402, 1412 (7th Cir.1994) (en banc)) (alterations in original). The counties ask us to expand their rights under-Kentucky law,.and we must refuse.
We nevertheless decline to certify the question to the Kentucky Supreme Court. The Kentucky Supreme Court is authorized to receive certified questions from both United States District Courts and United States Courts of Appeal. Ky. Civ; R. 76.37(1). When a party seeks certification of a question from both the district court and our court, we must therefore exercise our own discretion whether to certify, in addition to or instead of reviewing the district court’s exercise of its discretion. The counties initiated this lawsuit in federal court, and they did not ask for certification until after the district court ruled against them. “[Certification is disfavored where a plaintiff files in federal court but then, in light of an unfavorable judgment, seeks refuge in a state forum.” Geronimo v. Caterpillar, Inc., 440 Fed.Appx. 442, 449 (6th Cir.2011). We are not persuaded by the counties’ argument that they filed in federal court because of *824“the virtual certainty that ... the state court action [would have been] removed to federal court.” Appellant’s Br. at 27. To the extent that the counties did, in fact, believe that state courts provided a better forum to consider their novel legal argument, they should have filed in state court or at least sought certification before the district court ruled on the merits of the claim. Town of Smyrna, Tenn. v. Mun. Gas Auth. Of Ga. 723 F.3d 640, 649 (6th Cir.2013) (“The appropriate time to seek certification of a state-law issue is before a District Court resolves the issue, not after receiving an unfavorable ruling.”).
III. Conclusion
For these reasons, we AFFIRM the judgment of the district court.
. In the circuits that contain large cities, the county attorneys also take on a separate role of representing the commonwealth in civil cases in their own counties. Ky.Rev.Stat. § 69.210(4). Although some of the county attorneys appearing in this lawsuit are empowered to represent the commonwealth, they are not representing the commonwealth in this proceeding.
