PARKER, Justice.
Deborah Michelle Blackmon (“Deborah”) and the estate of Brian Alan Black-mon (“the estate”) appeal from a partial summary, judgment entered in favor of Renasant Bank and against them by the Mádison Circuit Court. We dismiss the appeál as being from a nonfinal judgment.
Facts and Procedural History
On November 8, 2004, Deborah and her husband Brian Alan Blackmon (hereinafter collectively referred to as “the Black-mons”) executed an agreement establishing a home-equity line of credit with Rena-sant Bank secured by a mortgage on the Blackmons’ house. The affidavit testimony of Jerry Harris, first vice president of Renasant Bank, indicates that, also on November 8, 2004, the Blackmons made an initial draw on their home-equity line of credit in the amount of $110,000. Harris’s affidavit states that, from July 21, 2006, .to June 6, 2013, the Blackmons made a total of 125 withdrawals on the home-equity line of credit totaling “approximately $387,929.00,” In addition to making withdrawals on the home-equity line of credit, the Blackmons also made payments on the home-equity line of credit during that time.
On June 14, 2013, Brian Alan Blackmon diéd. Harris’s affidavit states that, following Brian Alan Blackmon’s death, Deborah “made five separate payments” on the home-equity line of credit. However, the payments made by Deborah did not satisfy the entirety of the money the Blackmons owed Renasant Bank Under the terms of the home-equity line of credit, and Deborah failed to make any additional payments. Deborah denied that she had executed the home-equity line of credit or the mortgage and, thus, denied liability for any outstanding balance due under the home-equity line of credit. Harris’s affidavit states that the home-equity line of credit “is currently in default.” Harris’s affidavit states: “The balance on [the home-equity line of credit] as of June 23, 2015, is $129,545.86, inclusive of principal, interest and late fees,” Harris’s affidavit further states that “[t]he total amount due to Re-nasant Bank at this time, inclusive of principal, interest and attorney fees is $146,545.86.”
Oñ June 5, 2014, Renasant Bank sued Deborah and the estate seeking a judgment declaring that the Blackmons had executed the agreement establishing a home-equity line of credit with Renasant Bank and a mortgage on the Blackmons’ house securing the home-equity line of credit and asserting a claim of breach of contract seeking to recover the amount of money owed under the terms of the home-equity line of credit. On July 7, 2014, Deborah and the estate filed an answer to Renasant Bank’s complaint and asserted a counterclaim, requesting a judgment declaring that the mortgage on the Black-mons’ house was not enforceable.
On May 4, 2015, by leave of the circuit court, Renasant Bank filed an amended complaint against Deborah and the estate. Renasant Bank reasserted its breach-of-contract claim and asserted additional claims for “equitable mortgage,” “open account,” and “account stated.” Through these various theories of recovery, Rena-sant Bank’s sole request for damages was the outstanding balance owed on the home-equity line of credit. On August 21, 2015, Renasant Bank filed a second amended complaint against Deborah and the estate. In addition to the claims detailed above, Renasant Bank asserted the following claims: unjustenrichment, money had and received, “quasi-contract,” and “constructive trust.” Through these various theories of recovery, Renasant Bank’s sole request for damages was the outstanding balance owed on the home-equity line of credit.
On November 12, 2015, Renasant Bank filed a motion for a summary judgment. On December 31, 2015, the- circuit court entered a -partial summary judgment in favor of Renasant Bank on its claims alleging unjust enrichment and money had and received in the amount of $142,612.85.’ The circuit court specifically stated that “[a]ll other counts asserted by the parties remain pending.”
On January 28, 2016, Deborah and the estate filed a motion to alter, amend, or vacate the circuit court’s partial summary judgment in favor of Renasant Bank. On February 23, 2016, the circuit court denied-Deborah and the estate’s postjudgment motion.
On March 28, 2016, Deborah and the estate purported to appeal the circuit court’s December 31, 2015, partial summary judgment in favor of Renasant Bank. On November 28, 2016, the clerk of the Supreme Court entered an order remanding the case to the circuit court because all the claims pending before the circuit court had not been adjudicated in the circuit court’s December 31, 2015, partial summary judgment. On remand, upon motion of Deborah and the estate, the circuit court certified its December 31, 2015, partial summary judgment in favor of Rena-sant Bank as final pursuant to Rule 54(b), Ala. R. Civ. P.
Standard of Review
“Whether the action involves separate claims and whether there is a final decision as to at least one of the claims are questions of law to which we will apply a de novo - standard of review.” Scrushy v. Tucker, 955 So.2d 988, 996 (Ala. 2006)(em-phasis added).
Discussion
Although neither party challenges the appropriateness of the circuit court’s Rule 54(b) certification of its December 31, 2015, partial-summary-judgment order in favor of Renasant Bank, “it is well settled that this Court may consider, ex mero motu, whether a judgment or order is sufficiently final to support an appeal.” Natures Way Marine, LLC v. Dunhill Entities, LP, 63 So.3d 615, 618 (Ala. 2010). In the present case, as noted above, the circuit court certified as final pursuant to Rule 54(b) its December 31, 2015, partial summary judgment as to Re-nasant Bank’s unjust-enrichment and money-had-and-received claims against Deborah and the estate. This Court has stated that “ ‘[n]ot every order has the requisite element of finality that can trigger the operation of Rule 54(b).’ ” Dzwonkowski v. Sonitrol of Mobile, Inc., 892 So.2d 354, 361 (Ala. 2004) (quoting Goldome Credit Corp. v. Player, 869 So.2d 1146, 1147 (Ala. Civ. App. 2003) (emphasis omitted)). We will first consider whether the circuit court’s Rule 54(b) certification of its December 31, 2015, partial summary judgment is appropriate. .
Rule 54(b) states, in relevant part:
“When more than one claim for relief is presented in an action, whether as a claim, counterclaim, cross-claim, or third-party claim, or when multiple parties are involved, the court may direct the entry of a final judgment as to one or more but fewer than all of the claims or parties only upon an express determination that there is no just reason for delay and upon an express direction for the entry of judgment.”
Clearly, Renasant Bank’s complaint involves multiple claims against multiple parties. “‘[F]or a Rule 54(b) certification of finality to be effective, it must fully adjudicate at least one claim or fully dispose of the claims as they relate to at least one party.’ Haynes v. Alfa Fin. Corp., 730 So.2d 178, 181 (Ala. 1999).” Scrushy, 955 So.2d at 996.
We must consider whether Renasant Bank’s unjust-enrichment and money-had- and-received claims were separate and distinct claims that were fully adjudicated by the circuit court’s December 31, 2015, partial summary judgment. This Court considered a very similar issue in Scrushy. In North Alabama Electric Cooperative v. New Hope Telephone Cooperative, 7 So.3d 342, 345 (Ala. 2008), this Court summarized the applicable law from Scrushy:
“The Scrushy Court quoted with approval the United States Court of Appeals for the Seventh Circuit for ‘“certain rules of thumb to identify those types of claims that can never be considered separate” ’ for purposes of Rule 54(b). 955 So.2d at 998 (quoting Stearns v. Consolidated Mgmt., Inc., 747 F.2d 1105, 1108 (7th Cir. 1984)). One such rule is that ‘ “ ‘claims cannot be separate unless separate recovery is possible on each.... Hence, mere variations of legal theory do not constitute separate claims.’ ” ’ Id. (quoting Stearns, 747 F.2d at 1108-09, quoting in turn Amalgamated Meat Cutters v. Thompson Farms Co., 642 F.2d 1065, 1071 (7th Cir. 1981)). The Scrushy Court also noted the similar rule of the United States Court of Appeals for the SecondCircuit, see Rieser v. Baltimore & Ohio R.R., 224 F.2d 198, 199 (2d Cir. 1955), which was summarized by the commentators of Federal Practice and Procedure:
“ ‘ “A single claimant presents multiple claims for relief under the Second Circuit’s formulation when the possible recoveries are more than one in number and not mutually exclusive or, stated another way, when the facts give rise to more than one legal right or cause of action .... However, when a claimant presents a number of legal theories, but will be permitted to recover only on one of them, the bases for recovery are mutually exclusive, or simply presented in the alternative, and plaintiff has only a single claim for relief for purposes of Rule 54(b).” ’
“955 So.2d at 998 (quoting 10 Charles Alan Wright et al., Federal Practice & Procedure § 2657 (3d ed. 1998)(foot-notes omitted)).”
In Scrushy, this Court adopted the principles discussed above and concluded that “the various claims in the complaint [at issue in that case were] not all variations on a single theme.” 955 So.2d at 998. This Court so concluded because some of the claims asserted by the plaintiff in that case sought damages that other of the claims did not. See id. (stating that “[the plaintiffs] alleged breach of duty in accepting bonuses that HealthSouth was riot legally obligated to pay is a sufficiently separate breach that is not alleged elsewhere in the complaint”).
In the present case, Renasant Bank alleges the following claims against Deborah and the estate: a claim seeking a judgment declaring that Deborah executed the agreement establishing a home-equity line of credit with Renasant Bank and a mortgage on the Blackmons’ house securing that line of credit; breach of contract; “equitable mortgage”; “open account”; “account stated”; unjust enrichment; money had and received; “quasi-contract”; and “constructive trust.’-’ Unlike in Scrushy, the only damages requested by Renasant Bank for each of the above-asserted claims is the outstanding balance Renasant. Bank alleges Deborah and the estate-owe under the home-equity line of credit. Although Renasant Bank has asserted several different legal theories, it has -requested the same damages as to each claim. In fact, we note that Renasant Bank states that all of its claims, including its equitable claims, “originated” from “the written contract.” Renasant Bank’s brief, at p. 28. According to Renasant Bank, there is only one recovery possible for each claim: the outstanding balance under the home-equity line of credit. Therefore, under the principles set forth in Scrushy, Renasant Bank’s several claims are actually just one claim, which the circuit court’s December 31, 2015, partial summary judgment did not fully adjudicate. Consequently, the adjudication of Renasant Bank’s unjust-enrichment and money-had-and-received claims are not appropriate for Rule 54(b) certification; the circuit court’s partial summary judgment did not fully adjudicate a single claim. See James v. Alabama Coalition for Equity, Inc., 713 So.2d 937, 942 (Ala. 1997) (“ ‘Only a fully adjudicated whole claim against a pftrty may be certified under Rule 54(b). See Liberty Mutual Ins. Co. v. Wetzel, 424 U.S. 737, 742-44, 96 S.Ct. 1202, 1206, 47 L.Ed.2d 435 (1976).’ ’•’ (quoting Aktiengesellschaft v. Smoked Foods Prods. Co., 813 F.2d 81, 84 (5th Cir. 1987))).
Conclusion
We dismiss the appeal as being from a nonfinal judgment.
APPEAL DISMISSED.
Stuart, Bolin, and Wise, JJ., concur.
Shaw, J., concurs specially.
. We note that Deborah contests the fact that she executed the documents establishing the home-equity line of credit and the mortgage document.
. We note that Deborah and the estate filed a third-party complaint against Brenda G. Day, the notary public who notarized the home-equity line of credit agreement and the mortgage, asserting various claims. On March 24, 2016, the circuit court entered a partial summary judgment in favor of Day as to some of the third-party claims against her; the circuit court did not certify that judgment as final pursuant to Rule 54(b). Day is not a party to the appeal before this Court.
. In its partial summary judgment in favor of Renasant Bank, the circuit court awarded Re-nasant Bank $142,612.85 of the $146,545.86 it requested in damages. Based on die fact that the circuit court awarded the majority of the damages requested by Renasant Bank, it would appear that the circuit court adjudicated all the claims against Deborah and the estate. However, the circuit court specifically-stated in its partial summary judgment that “[a]ll other counts [besides unjust enrichment and money had and received] asserted by the parties remain pending.” Accordingly, we must conclude that the circuit court did not fully adjudicate the claims asserted by Rena-sant Bank against Deborah and the estate.
. We also note that Renasant Bank’s unjust-enrichment claim (which was adjudicated by the circuit court’s partial summary judgment) and its breach-of-contract claim (which remains pending in the circuit court), which are based on the same facts and contract, are mutually exclusive. See, e.g., Lass v. Bank of America, N.A., 695 F.3d 129, 140 (1st Cir. 2012) ([D]amages for breach of contract and unjust enrichment are mutually exclusive .... ”); Univalor Trust, SA v. Columbia Petroleum, LLC, 315 F.R.D. 374, 382 (S.D. Ala. 2016) (”[T]he existence of an express contract extinguishes an unjust enrichment claim altogether because unjust enrichment is an equitable remedy which issues only where there is no adequate remedy at law.”); Shedd v. Wells Fargo Home Mortg., Inc., Civil Action No. 14-00275-CB-M (S.D. Ala. Nov. 17, 2014) (not reported in F. Supp. 3d) (”[B]reach of contract and unjust enrichment are mutually exclusive when both claims are based on the same set of facts.); Clark v. Green Tree Servicing LLC, 69 F.Supp.3d 1203, 1222 (D. Colo, 2014) (noting, that plaintiff may plead contract claim and estoppel claim in the alternative but may not ultimately prevail on both); Superior Edge, Inc. v. Monsanto Co., 44 F.Supp.3d 890, 900 (D. Minn. 2014) (not--tag that party cannot recover under both a quasi-contract and express-contract theory); Naiser v. Unilever U.S., Inc., 975 F.Supp.2d 727, 748 (W.D. Ky. 2013) (“[Ujnjustenrichment has no application in a situation where there is an explicit contract which has been performed.’ ); Harrell v. Colonial Holdings, Inc., 923 F.Supp.2d 813, 826-27 (E.D. Va. 2013) (noting that breach of contract and unjust enrichment are alternative theories of recovery); Miami Valley Mobile Health Servs., Inc. v. ExamOne Worldwide, Inc., 852 F.Supp.2d 925, 939 (S.D. Ohio 2012) (noting that breach of express contract, breach of implied contract, and unjust enrichment are alternative claims); Vives v. Rodriguez, 849 F.Supp.2d 507, 515 n.6 (E.D. Pa. 2012) (same); CoMentis, Inc. v. Purdue Research Found., 765 F.Supp.2d 1092, 1098 (N.D. Ind. 2011) (same); CLN Props., Inc. v. Republic Servs., Inc., 688 F.Supp.2d 892, 902 (D. Ariz. 2010) (same); Scowcroft Grp., Inc. v. Toreador Res. Corp., 666 F.Supp.2d 39, 44 (D.D.C. 2009) (” [Tjhere can be no claim for unjust enrichment when an express contract exists between the parties.’ ” (quoting Schiff v. American Ass’n of Retired Persons, 697 A.2d 1193, 1194 (D.C. 1997))); Ryffel Family P’ship, Ltd. v. Alpine Country Constr., Inc., 386 Mont. 165, 171, 386 P.3d 971, 977 (2016) ([Bjreach of contract and unjust enrichment are mutually exclusive theories of recovery.-”); Lee v. Shim, 310 Ga.App. 725, 733, 713 S.E.2d 906, 913 (2011) (noting that breach of contract and unjust enrichment are mutually exclusive claims); and Russell v. Russell, 91 Conn.App. 619, 638, 882 A.2d 98, 111 (2005) ("[Ujnjust enrichment and breach of contract are mutually exclusive theories of recovery.”). It would not be prudent to try these mutually exclusive claims in piecemeal fashion.
