Before RILEY, Chief Judge, COLLOTON and SHEPHERD, Circuit Judges.
                              ____________

SHEPHERD, Circuit Judge.
       Eighty-seven Minnesota counties (Counties) filed a class-action suit against the
Appellees, various loan originators and servicers (Lenders), alleging that the Lenders’
use of the Mortgage Electronic Registration System (MERS) deprived the Counties
of recording fees on mortgage assignments by allowing parties to bypass recordation
with the Counties themselves. The Lenders removed the case to federal court and
filed a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), which the
district court1 granted. The Counties appeal, asserting that the district court erred in
determining that Minnesota’s Recording Act was not mandatory and that the
Counties’ unjust enrichment and public nuisance claims failed in the absence of a
recording requirement. The Counties also request that we certify a question to the
Minnesota Supreme Court regarding the interpretation of Minnesota’s Recording Act.
We decline to certify a question to the Minnesota Supreme Court, and affirm the
district court’s dismissal of the Counties’ claims.

                                           I.

       Under Minnesota law, mortgages on real property are generally recorded in the
county recorder’s office in the county where the real property is located. The advent
of MERS altered this structure by establishing a national electronic registry for
tracking mortgages. MERS does not originate, assign, or service the mortgages. It
charges a fee when members record or transfer a mortgage on the registry. Upon
initial recording, mortgages are recorded with the county recorder and MERS
becomes the mortgagee of record. With subsequent transfers, MERS remains the
mortgagee of record in the county property records, but tracks the transfers for priority
purposes on its registry. Transfers of mortgages are not recorded in the county where
the property is located. The Lenders in this suit are members of MERS who register
and track changes on the mortgages they maintain in the MERS database.


      1
      The Honorable David S. Doty, United States District Judge for the District of
Minnesota.

                                          -2-
       The Counties brought this class action in state court alleging that the Lenders
violated Minnesota law by allowing mortgagees to circumvent recordation in the
counties’ recording offices. The Counties allege that this failure to record caused the
loss of statutory recording fees and created gaps in chains of title. The Counties
sought a declaration that the Lenders violated Minnesota law by assigning mortgages
without recording the assignment in the appropriate county recorder’s office and
asserted claims for unjust enrichment and public nuisance. The Lenders removed the
case to federal court and filed a motion to dismiss under Federal Rule of Civil
Procedure 12(b)(6).

       The district court granted the Lenders’ motion to dismiss, finding that there was
no duty to record a mortgage assignment under Minnesota law. The court determined
that the operative language “shall be recorded” in the Minnesota Recording Act does
not require recordation of land transfers, but instead informs parties where they should
record their instrument if they desire the benefits of recordation, namely the
establishing of priority. The district court also dismissed the Counties’ claims for
unjust enrichment and public nuisance because they could not survive in the absence
of a duty to record. This appeal follows.

                                          II.

       We first review whether the district court erred in determining that the
Minnesota Recording Act does not impose a mandatory recording requirement for all
mortgages and subsequent assignments. We review a district court’s interpretation of
state law de novo. David v. Tanksley, 

, 930 (8th Cir. 2000). In
interpreting state law, we are bound by the decisions of the state’s highest court. 

allege that the Recording Act imposes a duty to record all mortgages




                                          -3-
and assignments with the county in which the real property is located, resulting in
MERS unlawfully depriving the Counties of the benefits of such recordation.

      Under the Minnesota Recording Act,

   [e]very conveyance of real estate shall be recorded in the office of the county
   recorder of the county where such real estate is situated; and every such
   conveyance not so recorded shall be void as against any subsequent purchaser
   in good faith and for a valuable consideration of the same real estate, or any
   part thereof, whose conveyance is first duly recorded.

Minn. Stat. § 507.34. Minnesota courts interpreting this statute have determined that
it does not impose a duty to record all mortgages and assignments; rather it provides
a mortgagee with guidance should he wish to protect his mortgage against subsequent
purchasers or other claimants. See Citizens State Bank v. Raven Trading Partners,
Inc., 

, 278 (Minn. 2010) (“The purpose of the Minnesota Recording
Act is to protect recorded titles against the gross negligence of those who fail to record
their interests in real property.”); Jackson v. Mortg. Elec. Registration Sys., Inc., 

, 495 (Minn. 2009) (“The Recording Act creates no obligations; rather it
uses recording to resolve disputes between parties who have no contractual
relationship, but who lay claim to the same title . . . . By contrast, the foreclosure by
advertisement statutes prescribe mandatory requirements which must be met for a
party to proceed under the statutes.”); Miller v. Hennen, 

, 369 (Minn.
1989) (explaining that the purpose of the Recording Act is to protect bona fide
purchasers); Claflin v. Commercial State Bank of Two Harbors, 

, 248
(Minn. Ct. App. 1992) (“The purpose of [the Minnesota Recording Act] is to protect
those who purchase real estate in reliance upon the record.”). Because we believe
Minnesota case law establishes that Minnesota law imposes no duty to record a
mortgage or a mortgage assignment with the county recorder, the district court did not
err in its determination that there was no mandatory recording requirement under
Minnesota law.

                                           -4-
                                          III.

       We next consider whether the district court erred in dismissing the Counties’
unjust enrichment and public nuisance claims on the basis that they could not survive
in the absence of a mandatory recording statute. We review a district court’s grant of
a motion to dismiss for failure to state a claim under Federal Rule of Civil Procedure
12(b)(6) de novo. Botten v. Shorma, 

, 980 (8th Cir. 2006). The Counties
allege that the Lenders have been unjustly enriched by enjoying the benefits conferred
by recording without paying the recording fees that otherwise would be paid to the
individual counties. The Counties also allege that allowing mortgagees to utilize
MERS and bypass the county recording system has resulted in a public nuisance by
interfering with the Counties’ abilities to keep accurate land records.

       Our court has recently held that a county cannot state a claim for unjust
enrichment when there is no duty under state law to record mortgages or subsequent
assignments. See Brown v. Mortg. Elec. Registration Sys., Inc., 

, 935
(8th Cir. 2013) (“Without a duty to record, . . . Lenders have retained nothing of value
to which they are not entitled, and there is nothing they could be required to restore
to the county.”). Other courts have reached the same conclusion. See, e.g., Macon
Cnty., Ill. v. MERSCORP, Inc., 

, 714 (7th Cir. 2014) (“[T]he defendants
are bypassing the County’s recording system, as they are entitled to do because there
is no requirement that either the initial granting of a mortgage or its assignment be
recorded, let alone that the assignment of a promissory note be recorded.”). Without
a duty to record, the Counties cannot state a claim for unjust enrichment.

       Regarding the Counties’ public nuisance claims, we decline to consider the
issue here because the Counties advance a claim that differs from the theory presented
before the district court. See S. Wine & Spirits of Am., Inc. v. Div. of Alcohol and
Tobacco Control, 

, 807 (8th Cir. 2013) (explaining that a question is

                                          -5-
waived if it is not presented to the district court). Because the Counties did not raise
the claim before the district court, we deem it waived. We thus affirm the district
court’s dismissal of both the unjust enrichment and public nuisance claims.

                                           IV.

       Finally, the Counties assert that the question of whether the Minnesota
Recording Act imposes a duty to record all mortgages and subsequent assignments is
a novel question of state law that warrants certification of the question to the
Minnesota Supreme Court. “[A]bsent a close question of state law or a lack of state
guidance, a federal court should determine all the issues before it.” Anderson v. Hess
Corp., 

, 895 (8th Cir. 2011). Minnesota’s application of the Recording
Act is not a close question of state law where state-court guidance is lacking. See, e.g.,
Citizens State 

. Minnesota courts have interpreted the Act
in numerous instances, and the issue before us requires straightforward application of
this case law. See 

(declining to exercise Burford abstention
because “[t]his is a standard enforcement proceeding requiring the federal court to
apply Arkansas state law in a way that has already been interpreted by Arkansas state
courts.”). This is not a close question of state law that necessitates certification of a
question to the Minnesota Supreme Court. We decline the Counties’ request.

                                           V.

       For the foregoing reasons, we affirm the judgment of the district court granting
the Lenders’ motion to dismiss and decline to certify the question regarding the
interpretation of the Minnesota Recording Act to the Minnesota Supreme Court.
