Chief Justice JEFFERSON
delivered the opinion of the Court.
In this original proceeding, the question is whether Kellogg Brown
&
Root, Inc. (“KBR”), as a non-signatory to a contract containing an arbitration clause, must arbitrate its claims against Unidynamics, Inc. (“Unidynamics”) and MacGREGOR (FIN) Oy (“MacGregor”) — the signatories to the contract. The trial court denied MacGre-gor’s motion, which sought to compel KBR to pursue its claims in an ongoing arbitration between MacGregor and Unidynam-ics. The court of appeals held that the trial court abused its discretion and conditionally granted mandamus relief, ordering the trial court to vacate its order denying MacGregor’s motion and “issue an order compelling KBR to arbitrate all claims.” 126 S.W.3d 176, 184. KBR sought mandamus relief in this Court.
Approximately two months after KBR filed its petition here, the arbitration between MacGregor and Unidynamics concluded. As a result, the relief MacGregor requested in the lower courts — that KBR be compelled “to pursue its claims in the arbitration between MacGregor (FIN) and Unidynamics” — is no longer available. The case is not moot, however, because the parties continue to dispute whether KBR should be compelled to “arbitrate all claims” pursuant to the court of appeals’ order.
Id.
at 184. Because we conclude that KBR cannot be so compelled, we conditionally grant mandamus relief and order the court of appeals to vacate its order.
I
Factual Background
In October 1999, MacGREGOR (USA), Inc. contracted with Ingalls Shipbuilding, Inc. (“Ingalls”) to build elevator trunks for two cruise ships. MacGREGOR (USA) assigned the contract to its sister compa
ny, MacGREGOR (FIN) Oy
(“MacGre-gor”). In August 2000, MacGregor subcontracted part of the job to Unidynamics, which agreed to fabricate a set of the elevator trunks for one of the ships.
In June 2001, Unidynamics and KBR entered into a second-tier subcontract, under which KBR agreed to furnish labor, equipment, and facilities to fabricate the elevator trunks. In the fabrication subcontract between MacGregor and Unidynamics, the parties agreed that: “Any disputes arising from the interpretation or application of this contract including any document pertaining thereto, shall be settled by arbitration in accordance with General Conditions (ECE 188), (Appendix 10).”
The second-tier subcontract between Unidynamics and KBR did not contain an arbitration provision.
After the ship buyer declared bankruptcy in November 2001, Ingalls directed MacGregor to cease work and notify its subcontractors to do the same. MacGre-gor directed Unidynamics to comply with “the same instructions that Ingalls gave MacGregor.” Unidynamics conveyed those instructions to KBR. On or around November 5, 2001, KBR ceased work, stored the elevator trunks and other equipment, and sent Unidynamics invoices for unpaid fabrication services and storage costs. Because KBR had not been paid in full, it asserted liens on the elevator trunk fabrications, parts, and other materials (the “collateral”).
A dispute then arose between MacGre-gor and Unidynamics regarding who owned the collateral and who owed KBR for the fabrication services and storage costs. The dispute stemmed from MacGregor and Unidynamics’ Agreement Concerning Passing of Title (the “Title Agreement”), executed on December 5, 2001, and fully incorporated into their fabrication subcontract. Among other things, the Title Agreement provided that full title to the collateral would pass irrevocably to MacGregor immediately after MacGregor made two payments to Unidy-namics, which were to occur no later than December 19, 2001. The Title Agreement further required Unidynamics to release the collateral to MacGregor upon MacGre-gor’s request. It is undisputed that MacGregor timely paid Unidynamics; however, Unidynamics asserted that the payments were ineffective to pass title to MacGregor. When MacGregor demanded that Unidynamics release the elevator trunks, Unidynamics refused. The collateral remained in KBR’s possession.
II
Procedural Background
In May 2002, pursuant to the arbitration provision in the fabrication subcontract, MacGregor asked the International Chamber of Commerce (“ICC”) to arbitrate its dispute with Unidynamics. Among other things, MacGregor sought: (1) damages for breach of contract by Unidynamics for failure to release the collateral, (2) a deter-
ruination as to which defendant owned the collateral, and (3) a determination regarding MacGregor’s proportionate responsibility for the storage costs KBR billed Uni-dynamics. Unidynamics filed an answer and asserted counterclaims. MacGregor and Unidynamics then commenced arbitration in Paris, France.
While the arbitration was proceeding, both MacGregor and Unidynamics demanded that KBR release the collateral. KBR refused the demands and, on September 17, 2002, filed suit against both companies in Harris County. KBR claimed that Unidynamics breached its contract and, in the alternative, that it was entitled to recover
quantum, meruit
damages against Unidynamics and MacGregor. KBR also sued for declaratory relief to determine which defendant owned the collateral. Subject to the court’s ruling on ownership, KBR sought a judicial declaration that it possessed valid constitutional and statutory liens against the collateral in its possession.
MacGregor answered and sought a temporary restraining order, temporary injunction, and permanent injunction directing KBR to release the collateral. Unidynamics opposed MacGre-gor’s application, arguing that the court action should be abated because the collateral’s ownership was “the very issue ... being arbitrated before the ICC.” MacGre-gor, Unidynamics, and KBR then negotiated an agreement, which the trial court entered as an Agreed Order. Pursuant to that order, MacGregor agreed to post a $1,000,000 bond and, upon presentation of the bond, KBR agreed to release the collateral to MacGregor.
MacGregor posted the bond on October 28, 2002.
Meanwhile, on October 18, 2002, MacGregor filed a motion to abate the state court proceedings pending its arbitration with Unidynamics or, in the alternative, to compel KBR to pursue its claims in the ongoing arbitration between MacGregor and Unidynamics. The trial court denied MacGregor’s motion. On December 19, 2002, MacGregor filed an interlocutory appeal and a petition for writ of mandamus in the court of appeals, contending that the trial court abused its discretion. The court of appeals dismissed the interlocutory appeal as moot and conditionally granted mandamus relief, ordering the trial court “to vacate its order denying MacGregor’s plea in abatement and motion to compel arbitration, to issue an order compelling KBR to arbitrate all claims, and to stay all proceedings pending arbitration.”
126 S.W.3d at 184-85.
On December 9, 2003, KBR petitioned this Court for a writ of mandamus. On February 4, 2004, while the petition was pending before us, the arbitration between MacGregor and Unidynamics concluded, and the ICC issued a final arbitration award. KBR does not contest that award.
HI
Mootness
As a preliminary matter, we must decide whether the ICC’s final arbi
tration award moots this mandamus proceeding. A case becomes moot if a controversy ceases to exist between the parties at any stage of the legal proceedings, including the appeal.
Allstate Ins. Co. v. Hallman,
159 S.W.3d 640, 642 (Tex.2005);
Bd. of Adjustment of San Antonio v. Wende,
92 S.W.3d 424, 427 (Tex.2002);
Williams v. Lara,
52 S.W.3d 171, 184 (Tex.2001). This case stems from the lower courts’ action on MacGregor’s motion to “compel[ ] KBR to pursue its claims in the arbitration between [MacGregor] and Uni-dynamics.” Because that arbitration is over, KBR can no longer be compelled to “join the arbitration.”
See
126 S.W.3d at 183 (concluding that the trial court abused its discretion by refusing to compel KBR to join the ongoing arbitration). The question, then, is whether this proceeding is moot.
A case is not rendered moot simply because some of the issues become moot during the appellate process.
See Allstate,
159 S.W.3d at 642-43 (holding that a dispute concerning attorney’s fees preserved a live controversy in an otherwise moot appeal);
Camarena v. Tex. Employment Comm’n,
754 S.W.2d 149, 151 (Tex.1988) (same). In this case, the court of appeals ordered the trial court “to issue an order compelling KBR to arbitrate all claims.” 126 S.W.3d at 184. Although it is no longer possible for KBR to join the Paris arbitration, the court of appeals’ ultimate directive has no temporal component. It requires KBR to “arbitrate all claims.”
The live controversy in this proceeding is whether KBR must arbitrate those claims that remain now that the arbitration between MacGregor and Unidynam-ics has concluded. KBR’s petition consisted of: (1) a breach-of-contract claim against Unidynamics; (2) in the alternative, a
quantum meruit
claim against Un-idynamics and MacGregor; and (3) a declaratory judgment action to determine the collateral’s owner and to establish that KBR possessed valid hens. The arbitrator determined that, pursuant to the Title Agreement between MacGregor and Unidynamics, title to the collateral passed from Unidynamics to MacGregor on December 10, 2001. KBR is satisfied with this resolution of the ownership dispute, and thus, we need not address whether the ownership dispute must be arbitrated. Additionally, we need not address whether KBR should be compelled to arbitrate its claims against Unidynamics, because the parties now agree that those claims are not subject to arbitration. Our inquiry is accordingly limited to determining whether KBR must arbitrate its
quantum meruit
and lien-validity claims against MacGregor.
IV
Discussion
The parties do not dispute the court of appeals’ holding that the arbitration provision at issue is governed by the Federal Arbitration Act (“FAA”).
See
9 U.S.C. §§ 1-16; 126 S.W.3d at 181. In general, a party seeking to compel arbitration under the FAA must establish that: (1) there is a valid arbitration agreement, and (2) the claims raised fall within that agreement’s scope.

749, 753 (Tex.2001);
In re Oakwood Mobile Homes, Inc.,
987 S.W.2d 571, 573 (Tex.1999). Doubts regarding an agreement’s
scope
are resolved in favor of arbitration because there is a presumption favoring agreements to arbitrate under the FAA.

52 S.W.3d at 753;
Cantella & Co. v. Goodwin,
924 S.W.2d 943, 944 (Tex.1996). However, “the presumption arises only after the party seeking to compel arbitration proves that a valid arbitration agreement exists,”
J.M. Davidson, Inc. v. Webster,
128 S.W.3d 223, 227 (Tex.2003), because “the purpose of the FAA was to make arbitration agreements as enforceáble as other contracts, not more so.”

Under the FAA, ordinary principles of state contract law determine whether there is a valid agreement to arbitrate.

21 Rev. Litig. 593, 632 (2002)). Federal and Texas state courts have recognized, however, that “[i]t does not follow ... that under the [FAA] an obligation to arbitrate attaches only to one who has personally signed the written arbitration provision”; instead, under certain circumstances, principles of contract law and agency may bind a non-signatory to an arbitration agreement.

Although state law determines the validity of an arbitration agreement, courts have applied both federal and state law to determine the related, but distinct, issue of whether non-signatory plaintiffs should be compelled to arbitrate their claims.
See, e.g., Bailey,
364 F.3d at 267-68 (applying federal law);
Bridas,
345 F.3d at 355-63 (applying federal law);
Fleetwood Enters. v. Gaskamp,

Lakeland Anesthesia, Inc. v. United Healthcare of La., Inc.,
871 So.2d 380, 392-95 (La.Ct.App.2004) (applying federal and state law). The FAA does not specify whether state or federal law governs, and the United States Supreme Court has not directly addressed the issue.
Federal courts of appeals, however, have frequently applied federal substantive law when deciding whether a non-signatory must arbitrate.
See, e.g., Bailey,
364 F.3d at 267 n. 6;
Bridas,
345 F.3d at 355-63;
InterGen N.V. v. Grina,

Int’l Paper Co.,
206 F.3d at 417 n. 4;
Thomson-CSF,
64 F.3d at 778-79. The Fourth and Fifth Circuits have reasoned that “ ‘federal substantive law of arbitrability’... resolve[s] this question,” because the determination of whether a non-signatory is bound “presents no state
law question of contract formation or validity.”
R.J. Griffin & Co. v. Beach Club II Homeowners Ass’n,
384 F.3d 157, 160 n. 1 (4th Cir.2004) (quoting
Int’l Paper Co.,
206 F.3d at 417 n. 4);
Bailey,
364 F.3d at 267 n. 6 (same). We are not convinced that state law plays no role in making this determination.
See Roosth,
27 S.W.3d at 208-09 (applying state law);
Dyer,
969 S.W.2d
at 520
(applying state law). Nevertheless, we are mindful of the extensive body of federal precedent that has explored the extent to which non-signatories can be compelled to arbitrate. Moreover, we recognize that it is important for federal and state law to be as consistent as possible in this area, because federal and state courts have concurrent jurisdiction to enforce the FAA.
See Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp.,
460 U.S. 1, 25, 103 S.Ct. 927, 74 L.Ed.2d 765 (1983). Our decision today rests on state law, but it is informed by persuasive and well-reasoned federal precedent.
Federal courts have recognized six theories, arising out of common principles of contract and agency law, that may bind non-signatories to arbitration agreements: (1) incorporation by reference; (2) assumption; (3) agency; (4) alter ego; (5) equitable estoppel, and (6) third-party beneficiary.
See, e.g., Bridas,
345 F.3d at 356.
Here, MacGregor asserts that KBR is bound to arbitrate under the doctrine of “direct benefits estoppel” — a type of equitable estoppel that federal courts apply in the arbitration context.
See, e.g., Bailey,
364 F.3d at 268;
Bridas,
345 F.3d at 361-62;
E.I. DuPont de Nemours & Co. v. Rhone Poulenc Fiber & Resin Intermediates, S.A.S.,
269 F.3d 187, 199-201 (3d Cir.2001);
Int’l Paper Co.,
206 F.3d at 418.
Under “direct benefits estop-pel,” a non-signatory plaintiff seeking the benefits of a contract is estopped from simultaneously attempting to avoid the contract’s burdens, such as the obligation to arbitrate disputes.
R.J. Griffin & Co.
at 160-61;
Bailey,
364 F.3d at 268;
Int’l Paper Co.,
206 F.3d at 418 (“[T]he doctrine recognizes that a party may be estopped from asserting that the lack of his signature precludes enforcement of the contract’s arbitration clause when he has consistently maintained that other provisions of the same contract should be enforced to benefit him.”);
Thomson-CSF,
64 F.3d at 778. Thus, a non-signatory plaintiff may be compelled to arbitrate if it seeks to enforce terms of a contract containing an arbitration provision.
See R.J. Griffin & Co.,
384 F.3d at 161-64;
Bailey,
364 F.3d at 268;
Bridas, 345
F.3d at 361-62 (“Direct benefits estoppel applies when a non-signatory ‘knowingly exploits the agreement containing the arbitration clause.’ ”) (quoting
E.I. DuPont de Nemours & Co.,
269 F.3d at 199);
Int’l Paper Co.,
206 F.3d at 418. For example, if a non-signatory’s breach-of-warranty and breach-of-contract claims are based on certain terms of a written contract, then the non-signatory cannot avoid an arbitration provision within that contract.
See Int’l Paper Co.,
206 F.3d at 418. If, however, a non-signato
ry’s claims can stand independently of the underlying contract, then arbitration generally should not be compelled under this theory.
See, e.g., R.J. Griffin & Co.,
384 F.3d at 164;
Bridas,
345 F.3d at 362.
Consistent with the federal doctrine of “direct benefits estoppel,” this Court has held that a non-signatory plaintiff may be compelled to arbitrate if its claims are “based on a contract” containing an agreement to arbitrate.
In re FirstMerit Bank,
52 S.W.3d at 755 (“[A] litigant who sues based on a contract subjects him or herself to the contract’s terms”). In
FirstMerit Bank,
the non-signatory plaintiffs sued the signatory defendant for, among other things, breach of contract, revocation of acceptance, and breach of warranty.
Id.
at 752-53, 755. By bringing the breach-of-contract and breach-of-warranty claims, the plaintiffs sought benefits that stemmed directly from the contract’s terms. We concluded that, by seeking to enforce the contract, the non-signatory plaintiffs “subjected themselves to the contract’s terms, including the Arbitration Addendum.”
Id.
at 756;
see also Roosth,
27 S.W.3d at 208 (“The nonsignatory cannot enforce specific terms of the agreement while seeking to avoid the arbitration provision.”).
The issue here is whether KBR sought to enforce terms of the fabrication subcontract by (1) bringing a
quantum meruit
claim against MacGregor, or (2) seeking a declaration that it possessed valid liens. We begin with
quantum meruit.
Quantum meruit
is an equitable remedy that “ ‘is based upon the promise implied by law to pay for beneficial services rendered and knowingly accepted.’ ”
Vortt Exploration Co., Inc. v. Chevron U.S.A., Inc.,
787 S.W.2d 942, 944 (Tex.1990) (quoting
Truly v. Austin,
744 S.W.2d 934, 936 (Tex.1988)). A party generally cannot recover under
quantum meruit
when there is a valid contract covering the services or materials furnished.
Murray v. Crest Constr., Inc.,
900 S.W.2d 342, 345 (Tex.1995);
Woodard v. S.W. States, Inc.,
384 S.W.2d 674, 675 (Tex.1964) (“Recovery on an express contract and on quantum meruit are inconsistent.”). A party to a contract may, however, seek alternative relief under both contract and quasi-contract theories. Pleading in the alternative does not defeat the effect of an arbitration clause that broadly covers all disputes between signatories that arise out of the underlying agreement. But in this case, KBR is not a signatory to 'the fabrication subcontract between MacGregor and Uni-dynamics; therefore, the scope of that subcontract’s arbitration clause does not answer whether KBR must arbitrate.
To advance its estoppel theory, MacGregor contends that KBR’s
quantum meruit
claim is “based on” the fabrication subcontract in the sense that KBR’s labor and services were linked inextricably to that subcontract. It is true, of course, that KBR was fabricating trunks that were at the contract’s core and that, in performing the work, KBR relied on the fabrication subcontract’s specifications. However, under “direct benefits estoppel,” a non-signatory plaintiff cannot be compelled to arbitrate on the sole ground that, but for the contract containing the arbitration provision, it would have no basis to sue. The work to be performed under a second-tier subcontract will inherently be related to and, to a certain extent, defined by contracts higher in the chain.
See
Black’s Law Dictionary 1464 (8th ed.2004) (defining subcontractor as “[o]ne who is awarded a portion of an existing contract by a contractor, esp. a general contractor”). If this were a sufficient basis for binding a non-signatory subcontractor, arbitration agreements would become easier to enforce than other contracts, counter to the FAA’s purpose.
See InterGen,
344 F.3d at
145-46 (noting that federal courts have “been hesitant to estop a nonsignatory seeking to avoid arbitration”).
We conclude that, under “direct benefits estoppel,” although a non-signatory’s claim may relate to a contract containing an arbitration provision, that relationship does not, in itself, bind the non-signatory to the arbitration provision. Instead, a non-signatory should be compelled to arbitrate a claim only if it seeks, through the claim, to derive a direct benefit from the contract containing the arbitration provision.
See Bailey,
364 F.3d at 268;
MAG Portfolio Consult., GMBH v. Merlin Biomed Group LLC,
268 F.3d 58, 61 (2d Cir.2001) (“The benefits must be direct—which is to say, flowing directly from the agreement.”);
Int’l Paper Co.,
206 F.3d at 417-18;
Thomson-CSF,
64 F.3d at 778-79;
In re FirstMerit Bank,
52 S.W.3d at 755.
In its
quantum meruit
claim against MacGregor, KBR seeks payment for services rendered. KBR provided services pursuant to its contract with Unidy-namics. KBR’s asserted right to payment therefore stems directly from the KBR-Unidynamics contract, not the fabrication subcontract. The fabrication subcontract includes no provision for paying KBR. In fact, KBR is effectively precluded from asserting rights under that contract, which expressly provides that “Approved use of any subcontractor creates no contractual relationship between the subcontractor and [MacGregor].”
Thus, we conclude that the court of appeals abused its discretion to the extent it compelled KBR to arbitrate its
quantum meruit
claim against MacGregor.
Having determined that KBR’s
quantum meruit
claim is not subject to arbitration, we turn to KBR’s lien-validity claims. KBR sought a judicial declaration that it possessed valid constitutional and warehouseman’s statutory liens.
See
Tex. Const, art. XVI, § 37; Tex. Bus. & Com. Code § 7.209(a)(1). The self-executing constitutional lien attaches to buildings and special-order articles that are made or repaired by mechanics, material men, and artisans who have a direct contractual relationship with the owner of the property.
See
Tex. Const. art. XVI, § 37;
CVN Group, Inc. v. Delgado,
95 S.W.3d 234, 240 (Tex.2002) (“[F]or constitutional liens that
are self-executing, there are no technical requirements.... ”);
First Nat’l Bank v. Whirlpool Corp.,
517 S.W.2d 262, 268 (Tex.1974) (holding that “the constitutional lien on manufactured chattels is available ... only upon articles made especially for a purchaser-pursuant to a special order and in accordance with the purchaser’s plans or specifications”);
Hayek v. W. Steel Co.,
478 S.W.2d 786, 790 (Tex.1972);
Strang v. Pray,
89 Tex. 525, 35 S.W. 1054, 1056 (1896). The warehouseman’s lien arises “against the bailor on the goods covered by a warehouse receipt or on the proceeds thereof in his possession for charges for storage or transportation ..., insurance, labor, or charges present or future in relaT tion to the goods, and for expenses necessary for preservation of the goods.... ” Tex. Bus.

Com.Code § 7.209(a)(1);
see also Flores v. Didear Van & Storage Co.,
489 S.W.2d 406, 407-09 (Tex.Civ.App.-Corpus Christi 1972, no writ) (discussing validity and enforceability of warehouseman’s lien).
In this Court, MacGregor’s sole argument for compelling arbitration of KBR’s lien-validity claims is that the claims require a determination of ownership, and thus, they are “based on” the Title Agreement within the fabrication subcontract.
Ownership was, of course, a central issue before and during the Paris arbitration. When the arbitration award resolved the ownership dispute, it also eliminated the only rationale that MacGregor has asserted thus far for arbitrating the liens’ validity-
We do not decide whether other arguments may exist to compel KBR to arbitrate the validity of its liens. To the extent a lien dispute still remains, the trial court is in the best position to determine, on principles we have declared today, whether it must be arbitrated.
y
Conclusion
We conditionally grant mandamus relief and order the court of appeals to vacate its order compelling KBR to “arbitrate all claims.”
See
126 S.W.3d at 184. The writ will issue only if the court of appeals fails to comply.
