OPINION
I. INTRODUCTION
This is an appeal from the confirmation of an arbitration award. The primary issue we address is whether the trial court abused its discretion by compelling binding arbitration between all of the parties over the objection of two of the defendants— now Appellants — Grand Homes 96, L.P. and Grand Homes, Inc. Appellants claim that they did not receive notice that arbitration could be compelled concerning the claims of Appellees David and Debra Loudermilk against them and that this lack of notice prevented them from raising the defense of waiver. Because Appellants either were not deprived of the opportunity to present their waiver defense to the *699 arbitrator or as a matter of law cannot establish the Loudermilks’ waiver of arbitration, we hold that the trial court did not err by compelling arbitration over Appellants’ objection. Because there is no record from the arbitration proceedings, Appellants’ other challenges to the arbitration award fail. Consequently, we will affirm.
II. Factual and Procedural Background
The Loudermilks purchased a house from Appellants. In connection with the purchase, the Loudermilks signed the purchase agreement submitted to them by Appellants. 1 The agreement contained an arbitration clause. 2 Appellants accepted the agreement, and, subsequently, the Loudermilks and Appellants, along with Home Owners Management Enterprises, Inc. d/b/a Home of Texas (HOME) and Warranty Underwriters Insurance Company (WUIC), all executed a limited warranty agreement. The warranty agreement also contained an arbitration clause. 3
About a year after purchasing the home, the Loudermilks sent a letter to Appellants identifying several items that needed repair, including cracks in the grout in the kitchen and around the fireplace, cracks in most rooms of the house, a severe crack at the window in the master bedroom, and cracked bricks on the exterior of the home. 4 When Appellants allegedly failed to make the requested repairs, the Loud-ermilks filed suit on August 29, 2003 in district court in Denton County, alleging negligence in the design and construction of their home’s foundation.
Approximately three months after filing their original petition, the Loudermilks filed an amended petition asserting additional causes of action for malice, breach of contract and warranty, violations of the DTPA, and fraud against Appellants and adding HOME and WUIC as defendants, alleging a cause of action for negligence against them. 5 The Loudermilks’ amended pleading also sought punitive damages, mental anguish damages, attorney’s fees, rescission of the contract for sale of the property, and prejudgment and post-judgment interest.
HOME and WUIC incorporated a plea in abatement into their original answer, notifying the trial court that “HOME and *700 WUIC are entitled to abate this matter for binding arbitration.” The basis for arbitration asserted by HOME and WUIC was that “[i]n accordance with Plaintiffs contract, all disputes relating to the home or warranty must be submitted to binding arbitration.” Approximately six months after filing their original petition, the Loudermilks again filed an amended pleading, this time alleging only causes of action for breach of warranty and fraud against Appellants and alleging only negligence and violations of the DTPA and the insurance code against HOME and WUIC.
HOME and WUIC filed their motion to compel arbitration on April 26, 2004. At the hearing on the motion to compel, HOME and WUIC’s attorney requested that the trial court refer the Loudermilks’ claims against HOME and WUIC to binding arbitration and then abate these same claims until the Loudermilks’ claims against Appellants were resolved. The Loudermilks’ attorney, however, pointed out that Appellants were parties to the warranty agreement and argued that if the trial court compelled arbitration of the Loudermilks’ claims against HOME and WUIC, it should also compel arbitration of the Loudermilks’ claims against Appellants. The trial court then, over Appellants’ objection, ordered all parties— HOME, WUIC, the Loudermilks, and Appellants — to arbitration.
Following the hearing on the motion to compel arbitration, the Loudermilks filed a motion requesting that the trial court appoint an arbitrator because the parties were unable to agree on an arbitrator. The trial court entered an order abating the case for arbitration and chose Greg Cokinos of Houston as the arbitrator. The Loudermilks, dissatisfied with the trial court’s choice, filed a motion to set aside its order appointing Mr. Cokinos as arbitrator and asked the trial court to reconsider.
Before the trial court had an opportunity to rule on the Loudermilks’ motion, Appellants filed a petition for writ of mandamus with this court, requesting a writ of mandamus directing the trial court to vacate its order compelling Appellants to binding arbitration. We issued an opinion denying Appellants’ petition for writ of mandamus.
In re Grand Homes 96, L.P.,
No. 02-04-00238-CV,
Subsequently, the trial court granted the Loudermilks’ motion to set aside its order appointing an arbitrator and appointed a new arbitrator, Dana McArthur. The parties went to arbitration, and the arbitrator issued a final arbitration award. The arbitrator rescinded the sale of the home and ordered Appellants to purchase the Loud-ermilks’ home for $292,000, plus closing costs. The arbitrator also ordered Appellants to pay the Loudermilks’ attorney’s fees, expert fees, litigation fees, and post-award interest. The award stated that “[t]he Loudermilks shall recover no damages from HOME/WUIC.”
The Loudermilks filed a motion to confirm the arbitrator’s award, and Appellants filed objections to the confirmation of the arbitrator’s award, along with motions to vacate and to modify the award. The trial court held a hearing and confirmed the arbitrator’s award. At Appellants’ request, the trial court entered findings of fact and conclusions of law. This appeal followed.
*701 III. TRial Court PRoperly Compelled Arbitration
The crux of the complaints made by Appellants in their first, second, and fourth issues is that they were surprised when, at the hearing on HOME and WUIC’s motion to compel arbitration, the Loudermilks urged arbitration and that they were harmed because they did not have an opportunity to prepare and present defenses to arbitration. Specifically, Appellants contend that the trial court erred by compelling binding arbitration of the Loudermilks’ claims against them because in the absence of a motion to compel arbitration filed by the Loudermilks, the trial court lacked jurisdiction; because the Loudermilks never demonstrated that their claims were within the warranty’s scope or that they satisfied the warranty’s conditions precedent to arbitration; and because the Loudermilks’ failure to file a motion to compel or to provide notice of their intent to arbitrate their claims against Appellants deprived Appellants of their right to present defenses to arbitration and to object to the court’s appointment of an arbitrator. We address these contentions in turn.
A. Trial Court Jurisdiction
It is clear that the trial court here had jurisdiction over the lawsuit.
See
Tex. Const, art. V, § 8 (stating that “[district court jurisdiction consists of exclusive, appellate, and original jurisdiction of all actions, proceedings, and remedies, except in cases where exclusive, appellate, or original jurisdiction may be conferred by this Constitution or other law on some other court, tribunal, or administrative body”). When two defendants in the lawsuit, HOME and WUIC, filed a motion to compel arbitration based on the arbitration provision set forth in the written warranty agreement, which Appellants also had signed, the trial court had a nondiscretion-ary duty to rule upon the arbitration issue, including which parties would be compelled to arbitration.
See, e.g., In re Weekley Homes, L.P.,
In short, we are not aware of any authority, nor have Appellants cited any authority, for the proposition that the trial court somehow lacks jurisdiction to compel a party in a pending lawsuit to arbitration when that party has executed multiple arbitration agreements or possesses jurisdiction to compel to arbitration only claims that are specifically mentioned in a motion. Accord Tex. Civ. Prac. & Rem.Code Ann. § 171.021(a) (Vernon 2005) (requiring only that motion to compel arbitration be filed by “a party”).
B. Claims Within Arbitration Agreements
Procedurally, a party seeking to compel arbitration has the initial burden to establish the arbitration agreement’s existence and to show that the to-be-arbitrated claims fall within the arbitration agreement’s scope.
In re Oakwood Mobile Homes, Inc.,
We will not find error by the trial court and are required to uphold the trial court’s ruling if it is proper on any grounds.
See Owens-Corning Fiberglas Corp. v. Malone,
The warranty agreement arbitration clause provides that “[a]ll requests for warranty performance, demand, disputes, controversies and difference[s] that may arise between the parties to this Limited
Warranty that cannot be resolved among the parties” shall be referred to arbitration. The arbitration provision in the sales contract provides that the parties “agree to submit to binding arbitration ... any dispute between Seller [Appellants] and Purchaser [the Loudermilks].” Clearly, the Loudermilks’ claims against Appellants for breach of warranty and fraud fall within the scope of both of these arbitration agreements executed by Appellants and the Loudermilks.
Because the trial court’s order compelling arbitration may be upheld under either of the arbitration provisions signed by Appellants and the Loudermilks, Appellants’ complaints that the Loudermilks failed to establish that they had met the conditions precedent to arbitration under the warranty agreement are moot. And, in any event, procedural questions — including whether procedures have been followed or excused and whether an unexcused failure to follow such procedures allows a party to avoid the duty to arbitrate — are left for the arbitrator to decide.
In re Weekley Homes,
C. Defense of Waiver
Having determined that valid arbitration agreements exist between the parties and that the claims asserted by the Loudermilks against Appellants fall within the scope of both arbitration agreements, we next address Appellants’ complaint that they were deprived of the opportunity to raise defenses to arbitration. Appellants claim that, because they had no notice that arbitration of the Loudermilks’ claims *703 against them would be addressed at the hearing on HOME and WUIC’s motion to compel, they were prevented from raising their defenses to arbitration. When pressed at oral argument concerning what specific defenses to arbitration Appellants would have liked to raise but were not prepared to raise at the hearing because of the lack of notice, Appellants indicated that they had wanted to raise the defense of waiver. 8 The exact procedure for resolving whether the party seeking to compel arbitration has waived arbitration is somewhat unsettled.
Traditionally, Texas courts framed the issue of whether a party had waived its right to compel arbitration as a question of law to be reviewed by the appellate court de novo.
Oakwood Mobile Homes, Inc.,
But here, we need not decide this issue because under either circumstance, Appellants’ unpreparedness to raise the defense of waiver at the hearing on HOME and WUIC’s motion to compel arbitration does not render the trial court’s decision to compel arbitration improper. If, under Howsam, waiver is a matter for the arbitrator to determine, then Appellants had the opportunity to raise their waiver defense before the arbitrator; no harm stemmed from Appellants’ lack of preparedness to raise it at the hearing on HOME and WUIC’s motion to compel. If, despite Howsam, waiver is still an issue of law that we decide de novo, then the record before us establishes that the Louder-milks did not waive their right to arbitrate.
Because public policy favors arbitration, there is a strong presumption against finding that a party has waived its right to arbitration; the burden to prove waiver is thus a heavy one.
Bruce Terminix Co.,
Courts will not find that a party has waived its right to enforce an arbitration clause by merely taking part in litigation unless it has substantially invoked the judicial process to its opponent’s detriment.
Bruce Terminix Co.,
Here, the Loudermilks did not file a motion for summary judgment or seek but fail to achieve a satisfactory result from litigation in the trial court before turning to arbitration. Instead, approximately eight months after the Loudermilks filed their original petition — when two of the defendants moved to compel arbitration— the Loudermilks requested that if the trial court decided to order arbitration, it compel arbitration of all claims against all defendants, including Appellants. As a matter of law, when the trial court compelled arbitration, the Loudermilks had not substantially invoked the judicial process to Appellants’ detriment.
See In re D. Wilson Constr. Co.,
Even if the Loudermilks’ actions could somehow, in light of the dearth of contrary case law, be construed as having substantially invoked the judicial process, Appellants cannot meet the heavy burden of showing that they were prejudiced by the Loudermilks’ actions. The suit was less than eight months old, and very little discovery had occurred. See id.
Appellants urge us to hold that the Loudermilks waived their right to arbitrate when they filed suit. Appellants rely upon what appears to be dictum in
Vireo P.L.L.C. v. Cates,
We therefore hold that the trial court did not eiT by compelling Appellants to arbitrate the Loudermilks’ claims against them. We overrule Appellants’ first, second, and fourth issues.
*705 IV. Choice of ArbitRator
In their third issue, Appellants argue that they were deprived of the benefits of arbitration under the sales contract. Specifically, Appellants contend that they had the right under the sales contract’s arbitration clause to select an arbitrator or to have one appointed by the American Arbitration Association.
Although the motion to compel hearing occurred in April 2004, due to intervening events like the original proceedings that Appellants filed, the arbitration did not take place until August 2005. During the interim, the Loudermilks filed a motion asking the trial court to appoint an arbitrator because the parties were unable to decide on one. The Loudermilks subsequently filed another motion to set aside the trial court’s first choice of an arbitrator. These motions were served on all parties, including Appellants. During the sixteen months between the selection of the initial arbitrator and the actual arbitration, Appellants did not respond to the Loudermilks’ motions or file their own motion requesting that an AAA arbitrator be appointed. When competing arbitration clauses exist in a case involving multiple defendants, complaints of the type now made by Appellants must be brought to the trial court’s attention. See Tex.R.App. P. 33.1. Because Appellants did not raise this complaint in the trial court, but instead waited to raise it until after they had fully participated in an arbitration that resulted in an award adverse to them, we hold that this complaint is not properly before us. We overrule Appellants’ third issue.
V. Arbitrator’s Award
In their fifth, sixth, and seventh issues, Appellants contend that the arbitrator exceeded her authority by granting remedies outside the warranty’s scope, manifestly disregarding the law of limitations, and miscalculating the rescission damages. The Loudermilks respond that because there is no record of the arbitration proceedings, this court must defer to the arbitrator.
Generally, an arbitration award is given the same effect as a final judgment of a court of last resort.
Nuno v. Pulido,
For an appellate court to have jurisdiction to review an arbitration award, an appellant must allege a statutory or common law ground to vacate the award.
Hisaw & Assocs.,
Although Appellants raise at least one of the statutory grounds for vacating an arbitration award, they have furnished no record of the arbitration proceedings to support their claim that the arbitrator exceeded her authority. The Loudermilks’ pleadings specifically pray for rescission of the sales contract and the other damages awarded, and the Loudermilks’ claims are clearly within the scope of both arbitration agreements. For these reasons, we cannot agree that the arbitrator exceeded her authority.
See Baker Hughes Oilfield Operations, Inc.,
Appellants also argue that the arbitrator committed errors in substantive law by disregarding the law of limitations and by miscalculating the rescission damages. These alleged errors in the application of substantive law by the arbitrator during the arbitration proceedings are not reviewable by the court on a motion to vacate an award.
Jamison & Harris,
We therefore overrule Appellants’ fifth, sixth, and seventh issues.
YI. Conclusion
Having overruled all seven of Appellants’ issues, we affirm the trial court’s judgment confirming the arbitrator’s award.
Notes
. The “Agreement,” as it is titled, reveals a medallion-type insignia at the top with the words "Grand Homes” inside it.
. The arbitration provision in this agreement provides for application of the Texas Arbitration Act and states, in part,
The parties agree to submit to binding arbitration any controversy hereafter arising between them, whether relating to the construction of the residence or any appliance, equipment or fixtures installed therein, title, warranties, negotiations, statements or representations before, at, or after this Agreement is signed or otherwise involving any dispute between Seller and Purchaser.
. The arbitration agreement in the warranty provides for application of the Federal Arbitration Act and states, in part, "[A]ny Unresolved Warranty Issue that you have with the Warrantor shall be submitted [to arbitration].” It also defines an Unresolved Warranty Issue as "[a]ll requests for warranty performance, demand, disputes, controversies and difference[s] that may arise between the parties to this Limited Warranty that cannot be resolved among the parties.”
. The warranty agreement provided that the home builder was the warrantor in years one and two of the warranty coverage and that the insurer was the warrantor in years three through ten of the warranty coverage and in years one and two if the builder defaulted.
. The Loudermilks also added Ready Cable, Inc. and Jerry L. Coffee, P.E. as defendants and alleged causes of action for negligence and breach of warranties against them. Because these two parties are not involved in this appeal, we will not detail the motions that they filed or how they were disposed of in the trial court.
. Appellants also filed a petition for writ of mandamus with the Texas Supreme Court, which was denied.
. Although at the hearing on HOME and WUIC’s motion to compel arbitration the trial court apparently based its order compelling arbitration on the arbitration clause in the warranty, in the findings of fact that the trial court made after confirming the arbitrator's award it specifically found that "[t]he Arbitrator had the authority to act pursuant to Section 18 of the Agreement between Plaintiffs and [Appellants],” which is the arbitration provision in the sales contract.
. Appellants do not assert that there was fraud, deceit, or misrepresentation involved in their signing of the agreements. Consequently, absent waiver, they are bound by the agreements.
