OPINION

Opinion by Justice EVANS.

Appellant Transcontinental Realty Investors, Inc. appeals from various rulings of the trial court arguing appellee lacks standing to assert claims as landlord. Appellant also contends that the trial court erred in its admission of expert witness testimony. We affirm.

BACKGROUND

Pursuant to the terms of a lease dated September 3, 2004, Sidney Wicks leased various commercial properties in Addison, Texas to appellant. On May 17, 2006, Wicks formed the Sidney Wicks Revocable Trust (Trust) in which he serves as the trustee. On May 17, 2006, Wicks executed an Assignment and Declaration in which he assigned and transferred "all of the right, title and interest of [Wicks] in and to any and all property held by [Wicks] ... whether now owned or hereafter acquired" to himself, as trustee of the Trust. Thereafter, the rent appellant paid under the lease was paid to the Trust.

On December 2, 2010, Wicks, individually, filed a petition against appellant for breach of the lease. On March 3, 2011, an amended petition was filed which substituted appellee [Wicks, as trustee of the Trust] as the plaintiff instead of Wicks in his individual capacity. Appellant filed an amended answer which asserted that the Trust lacked standing to bring its claims. On July 1, 2011, appellee filed a motion for summary judgment which the trial court granted solely as to appellant's liability for breach of the lease.

On September 6, 2011, Wicks executed and recorded a general warranty deed which transferred the real property at issue in the lawsuit to the Trust. The deed states that although the document was executed on September 6, 2011, there is an "effective date" of May 17, 2006. On September 6, 2011, Wicks also executed an Assignment and Assumption of Lease which assigned all of Wicks's rights and obligations under the lease to the Trust. Although executed on September 6, 2011, this document also provides for an "effective date" of May 17, 2006.

The issue of damages owed by appellant for breach of the lease proceeded to a jury trial in October 2012. The jury returned a verdict in favor of appellee in the amount of $1,066,277.14, plus interest, attorneys' fees and expenses. After the trial court denied appellant's motion for new trial, appellant perfected this appeal.

ANALYSIS

A. The Trial Court Did Not Err in Rulings Related to Appellee's Alleged Lack of Standing

In its first issue, appellant argues that the trial court erred in granting motions1 in appellant's favor and in instructing the jury because appellee lacks standing and is unable to assert claims as landlord under the lease. Whether a party has standing to pursue a cause of action is a question of law subject to de novo review. Nat'l Health Res. Corp. v. TBF Fin., LLC, 429 S.W.3d 125, 128 (Tex.App.-Dallas 2014, no pet.). Accordingly, although the different types of trial court orders from which appellant appeals may differ in the standard of review of factual determinations, all motions at issue in this appeal warrant a de novo standard of review because the sole issue presented for our review with respect to these motions — standing — is a matter of law. Mariner Health Care Of Nashville v. Robins, 321 S.W.3d 193, 200 (Tex.App.-Houston [1st Dist.] 2010, no pet.) ("Because a court's subject-matter jurisdiction is a question of law, Tex. Dep't of Parks & Wildlife v. Miranda, 133 S.W.3d 217, 226 (Tex.2004), whether a plaintiff has standing is a legal question we determine de novo.").

Specifically, appellant argues that Wicks, individually, is the party whose legal right has allegedly been breached and only in his individual capacity can Wicks properly invoke the jurisdiction of the court for claims under the lease. Appellant also argues that the lease was not properly conveyed to the Trust in May 2006. Finally, appellant asserts that even if the lease was properly conveyed to the Trust in May 2006 then, as a matter of law, the court's jurisdiction was not properly invoked at the time of the original filing because the suit was originally filed by Wicks, individually. Appellant frames all of these issues as a lack of standing to bring the claims for breach of lease and cites OAIC Commercial Assets, L.L.C. v. Stonegate Village, L.P., 234 S.W.3d 726, 738 (Tex.App.-Dallas 2007, pet. denied) in its reply brief.

Texas law is clear, and this Court has previously held numerous times, that a challenge to a party's privity of contract is a challenge to capacity, not standing. Nat'l Health Res. Corp., 429 S.W.3d at 129 ("Whether [a party] was the assignee of the lease between [the signatory parties] is not an issue of standing. [Citation omitted.] Rather, it is a question of whether [the alleged assignee] can recover in the capacity in which it sued, an issue that goes to the merits of [the alleged assignee's] claim."); John C. Flood of DC, Inc. v. SuperMedia, LLC, 408 S.W.3d 645, 651 (Tex.App.-Dallas 2013, pet. denied); King-Mays v. Nationwide Mut. Ins. Co., 194 S.W.3d 143, 145 (Tex.App.-Dallas 2006, pet. denied) ("A challenge to privity is a capacity issue, not standing, and requires compliance with rule 93," citing Pledger v. Schoellkopf, 762 S.W.2d 145, 145-46 (Tex. 1988) (per curiam)). Whether a party is entitled to sue on a contract "is not truly a standing issue because it does not affect the jurisdiction of the court; it is, instead, a decision on the merits." Nat'l Health Res. Corp., 429 S.W.3d at 128 (quoting Heartland Holdings Inc. v. U.S. Trust Co. of Tex., 316 S.W.3d 1, 6-7 (Tex.App.-Houston [14th Dist.] 2010, no pet.)). In John C. Flood of DC, Inc., we distinguished the informal reference to privity as standing from the technically accurate way to approach the issue in pleadings and motions as an issue of capacity:

408 S.W.3d at 651. Therefore, we agree with Wicks that, in the case before us, the issue is not whether he as trustee has standing to bring this action, but instead whether he can recover in the capacity in which he sued.

Appellant also complains under these issues that the trial court instructed the jury that the lease was assigned to the Trust in May 2006. Generally, all contracts are assignable. See Crim Truck & Tractor Co. v. Navistar Int'l Transp. Co., 823 S.W.2d 591, 596 (Tex.1992); In re FH Partners, L.L.C., 335 S.W.3d 752, 761 (Tex. App.-Austin 2011, no pet.). In this instance, Section 29.2 of the lease specifically provides for assignments:

Further, Section 27 of the lease entitled "Transfer of Landlord's Interest" provides that Wicks was relieved of his duties and obligations as landlord as long as the Trust assumed the obligations of the landlord. Specifically, Section 27 provides as follows:

On May 17, 2006, Wicks executed an Assignment and Declaration in which he assigned and transferred to the Trust "all of the right, title and interest of [Wicks] in and to any and all property held by [Wicks] ... whether now owned or hereafter acquired." In addition, Wicks and the Trust executed an Assignment and Assumption of Lease on September 6, 2011, with an effective date of May 17, 2006, which provides as follows:

Although assignments are usually effective on the date on which they are signed, there is no language in the lease which would require that the assignment only be effective upon execution. Thus, Wicks was not prevented from executing the Assignment and Assumption of Lease with a retroactive "effective date" of May 17, 2006. See Crowell v. Bexar Cnty., 351 S.W.3d 114, 117 (Tex.App.-San Antonio 2011, no pet.). Wicks's assignment of the lease to the Trust did not create new rights and, indeed, Wicks sued on behalf of the Trust merely to enforce the lease. See id. Appellant had agreed to the lease and paid rent to the Trust, so appellant is not harmed by the May 2006 retroactive effective date of the 2011 assignment. Accordingly, we overrule appellant's first issue.

B. The Trial Court Did Not Err in Admitting Expert Testimony

In its second issue, appellant argues that the trial court erred in admitting expert testimony regarding future damages under the lease. We review the trial court's determination regarding the admission of expert testimony under an abuse of discretion standard of review. See In re J.B., 93 S.W.3d 609, 619 (Tex.App.-Waco 2002, pet. denied). We reverse a judgment on the basis of evidentiary error — the erroneous admission of an expert's testimony — only if we conclude the error probably caused rendition of an improper judgment. See Boulle v. Boulle, 254 S.W.3d 701, 707 (Tex.App.-Dallas 2008, no pet.) (citing TEX.R.APP. P. 44.1(a)(1) and Gee v. Liberty Mut. Fire Ins. Co., 765 S.W.2d 394, 396 (Tex.1989)).

Appellant argues that the methodology used by appellee's expert, Arleen Cassidy, regarding future rent damages was erroneous and unreliable. Cassidy is an MAI appraiser with an M.B.A. in finance and twenty-eight years of experience appraising industrial properties. At Cassidy's first mention of a market rent study, appellant objected to relevance arguing replacement leases were already admitted in evidence making a hypothetical market rent study irrelevant. The trial court did not rule on the objection. Cassidy then testified in detail to every component of her calculation without objection from appellant either to her general methodology or her resulting calculation of future damages under the lease. Cassidy's calculation took into account one replacement lease for part of the leasehold that Wicks had already entered into by the time Cassidy first made her calculations. Appellant cross examined Cassidy extensively about a second replacement lease that appellant contends Cassidy's calculation did not take into account. During the cross examination, appellant moved to strike the expert testimony and asked for a sidebar discussion with the trial court. The trial court overruled the objection without holding a sidebar conference and no basis for the objection appears in the record. Appellant then led Cassidy through a calculation appellant contends is the correct way to calculate future damages and obtained Cassidy's agreement that the mathematics used resulted in $101,828 before discounting to present value. Cassidy, however, did not agree appellant's calculation was the proper way to calculate future damages under the lease.

Appellee argues appellant failed to object to Cassidy's methodology at any time before the trial court admitted Cassidy's testimony regarding her calculation of future damages and that an objection on relevancy grounds is not the same grounds as asserted on appeal. Appellant failed to object to the expert's testimony on the basis of improper methodology before or during trial and obtain a ruling from the trial court. See Pink v. Goodyear Tire & Rubber Co., 324 S.W.3d 290, 299-300 (Tex. App.-Beaumont 2010, pet. dism'd) ("The examination of an expert's methodology, technique, or foundational data is a task for the trial court in its role as gatekeeper. But, generally, a Robinson determination is `not an analysis that should be undertaken for the first time on appeal.'") (quoting Coastal Transp. Co. v. Crown Cent. Petroleum Corp., 136 S.W.3d 227, 233 (Tex. 2004)). For appellant to have preserved error for appellate review, appellant had to timely and specifically object to the evidence and obtain a ruling. Bay Area Healthcare Group, Ltd. v. McShane, 239 S.W.3d 231, 235 (Tex.2007) (citing TEX. R.APP. P. 33.1(a) and TEX.R. EVID. 103(a)). "Error is waived if the complaining party allows the evidence to be introduced without objection." Id. (citing Richardson v. Green, 677 S.W.2d 497, 501 (Tex.1984)). Rule 33.1(a) requires the record to demonstrate "a timely request, objection, or motion that stated the grounds for the ruling that the complaining party sought from the trial court with sufficient specificity to make the trial court aware of the complaint...." TEX.R.APP. PROC. 33.1(a). In the record before us, appellant neither objected nor obtained a ruling before Cassidy testified in detail to her methodology and the resulting future damages calculation. Accordingly, the trial court did not err and we overrule appellant's second issue.

CONCLUSION

We resolve appellant's issues against it and affirm the trial court's judgment.
