KEITH MASON AND MEGAN MASON, APPELLEES 

 

 

On Appeal from the 100th District Court 

Donley County, Texas 

Trial Court No. DCV-09-06600; Honorable Stuart Messer, Presiding 

 

January 13, 2014 

 

MEMORANDUM OPINION 

 

Before CAMPBELL and HANCOCK and PIRTLE, JJ.

Appellants, Wes Mason and his wife, Pam Mason, appeal the trial court‟s 

judgment following a jury trial awarding Appellees, Megan Mason and her then 

husband, Keith, $90,000 plus interest and attorney‟s fees.1 By four issues, Wes and 

Pam contend (1) the evidence is legally insufficient to support the finding of enhanced 

 

1

Keith is Wes and Pam‟s son. During the proceedings, Keith and Megan divorced and as part of 

the decree, Keith assigned his interest in the judgment to Megan. The assignment, however, does not 

operate to dispose of Keith as an Appellee in this appeal. 
2

market value caused by construction of a permanent improvement to the land; (2) Keith 

and Megan waived their independent ground of recovery for unjust enrichment when no 

element of unjust enrichment was requested or submitted to the jury; (3) Keith and 

Megan are not entitled to recover attorney‟s fees for unjust enrichment, or alternatively, 

the evidence established conclusively that the attorney‟s fees awarded were too high;

and (4) Keith and Megan are not entitled to recover prejudgment interest when they did 

not plead for it, or alternatively, the prejudgment interest was incorrectly calculated. By 

their brief, Keith and Megan concede issue three and agree attorney‟s fees are not 

recoverable in a claim for unjust enrichment. They consent to a removal of the award 

from the judgment.2 By reply brief, Wes and Pam expound on their original arguments

and challenge certain assertions made by Keith and Megan. Based on Keith and 

Megan‟s concession, we modify the trial court‟s judgment by deleting the award of

attorney‟s fees. We also modify the amount of prejudgment interest awarded. In all 

other respects, the judgment is affirmed.

BACKGROUND

Wes and Pam are the record owners of 160 acres in Donley County. The 

acreage is divided into two tracts of eighty acres each and is designated as their 

homestead. Believing that Wes and Pam had gifted eighty acres referred to as the 

north tract to her and Keith, Megan executed an agreement with Arrow Barn Builders to 

construct a custom horse barn which she and Keith would use to train horses and run a 

 

2

The award of attorney‟s fees provided for $15,000 through trial, $7,500 in the event of an 

unsuccessful appeal to this Court and $2,500 in the event of an unsuccessful appeal to the Texas 

Supreme Court.

horse-cutting business. The loan for the project was secured 100 percent by a 

certificate of deposit owned by Megan‟s mother. With Wes and Pam‟s full knowledge, 

Megan proceeded with her plans for the barn, a permanent improvement with a 

concrete slab, plumbing and electricity.

The builder engaged Old Pal Corporation to level the ground to prepare for 

construction of the barn. On Friday, May 2, 2008, Old Pal delivered a motor grader to 

the north tract and locked it. The next Monday, when a worker arrived to begin grading 

the property, he discovered the grader had been used by Wes without Old Pal‟s 

permission and that it had been damaged trying to remove tree stumps. Old Pal had to 

rent a grader to perform the work and also had to arrange for repair of the damaged 

grader. A demand for the expense of repair to the grader was made against Wes. 

When he did not pay it, Old Pal filed the original pleading in this proceeding on February 

26, 2009, alleging a negligence action against Wes and Megan. When Megan later 

called Old Pal to inquire about the grader, she was informed for the first time that suit 

had been filed. She then hired counsel and on November 30, 2009, filed a cross-claim 

against Wes asserting he was acting neither as her agent nor employee, and she also 

filed a third-party claim against Wes‟s wife, Pam. 

By her pleadings, Megan also alleged the following causes of action: (1) 

trespass to try title, (2) declaratory judgment enforcing the parol gift of the north tract

and (3) if title in the north tract remained with Wes and Pam, unjust enrichment if they 

were allowed to retain the full value of the improvement without repayment. 
4

Keith intervened in the suit aligning with Megan‟s interests. They alleged Wes 

and Pam fraudulently represented the gift of the north tract to them and continued to 

promise a deed. However, in July 2009, Wes and Pam negotiated a refinancing loan 

with First State Bank of Miami and represented they were the owners of the north tract.

Megan and Keith asserted Wes and Pam had full knowledge of their intent to erect an 

improvement on the north tract. That knowledge notwithstanding, Wes locked Megan 

and Keith out of the north tract thereby preventing access to the property. Megan and 

Keith added a fraud claim against Wes and Pam and a claim for declaratory judgment

against First State Bank of Miami alleging it did not have a valid lien on the north tract 

because Megan and Keith had no actual knowledge of a loan or purported lien on the 

north tract.

After partial settlement of the claims pertaining to Old Pal and First State Bank of 

Miami, the case proceeded to a jury trial on April 26, 2011. By its answers to questions 

in the charge, the jury found (1) Wes and Pam did not make a parol gift of the north tract 

to Megan and Keith, (2) the permanent improvement made to the market value of the 

north tract was $90,000 and (3) Wes and Pam did not commit fraud against Megan and 

Keith. On October 5, 2011, the trial court entered judgment that Megan and Keith 

recover from Wes and Pam the sum of $90,000, plus prejudgment interest in the 

amount of $8,593.15. The judgment further provided for the recovery of attorney‟s fees. 

Wes and Pam now challenge that judgment.

 

3Neither Old Pal nor First State Bank of Miami are parties to this appeal.

ISSUE ONE

Wes and Pam contend the evidence is legally insufficient to support the finding of 

$90,000 in enhanced market value caused by construction of a permanent improvement 

to the land. They assert Travis Lowe‟s expert opinion was unreliable and therefore 

constituted no evidence to support the jury‟s award. We disagree.

STANDARD OF REVIEW

In reviewing the legal sufficiency of the evidence, we must consider the evidence 

in the light most favorable to the fact finder‟s decision and indulge every reasonable 

inference that would support it. City of Keller v. Wilson, 168 S.W.3d 802, 822 (Tex. 

2005). We credit favorable evidence if a reasonable fact finder could and disregard 

contrary evidence unless a reasonable fact finder could not. Id. at 827. Evidence is 

legally sufficient if it would enable a reasonable and fair minded person to reach the 

finding under review. Id.

When a party challenges the legal sufficiency of an adverse finding on an issue 

for which it did not have the burden of proof, it must demonstrate there is no evidence to 

support the adverse finding. Exxon Corp. v. Emerald Oil & Gas Co., L.P., 348 S.W.3d 

194, 215 (Tex. 2011). Such a no-evidence challenge will be sustained when (1) there is 

a complete absence of evidence of a vital fact, (2) the court is barred by rules of law or 

of evidence from giving weight to the only evidence offered to prove a vital fact, (3) the 

evidence offered to prove a vital fact is no more than a mere scintilla, or (4) the 

evidence conclusively establishes the opposite of the vital fact. Jelinek v. Casas, 328 

S.W.3d 526, 532 (Tex. 2010) (citing City of Keller, 168 S.W.3d at 810). More than a 
6

scintilla of evidence exists when the evidence “rises to a level that would enable 

reasonable and fair-minded people to differ in their conclusions.” Ford Motor Co. v. 

Ridgway, 135 S.W.3d 598, 601 (Tex. 2004) (quoting Merrell Dow Pharms. v. Havner, 

953 S.W.2d 706, 711 (Tex. 1997)). Evidence does not exceed a scintilla if it is so weak 

as to do no more than to create a mere surmise or suspicion that the fact exists. Id. As 

long as the evidence falls within the zone of reasonable disagreement, this Court may 

not invade the fact finding role of the jurors, who alone determine the credibility of the 

witnesses, the weight to be given their testimony and whether to accept or reject all or a 

part of their testimony. City of Keller, 168 S.W.3d at 822.

An expert‟s testimony must be relevant to the issues and based upon a reliable 

foundation. TEX. R. EVID. 702. Expert testimony is unreliable if “there is too great an 

analytical gap between the data the expert relies upon and the opinion offered.” 

Enbridge Pipelines (E. Tex.) L.P. v. Avinger Timber, LLC, 386 S.W.3d 256, 262 (Tex. 

2012); Exxon Pipeline Co. v. Zwahr, 88 S.W.3d 623, 627 (Tex. 2002). If an appraiser 

utilizes improper methodology or misapplies established rules or principles, the resulting 

testimony is unreliable and must be excluded. Zwahr, 88 S.W.3d at 631.

An expert‟s opinion must be grounded in a sound evidentiary basis. Jelinek, 328 

S.W.3d at 536. “[I]f no basis for the opinion is offered, or the basis offered provides no 

support, the opinion is merely a conclusory statement and cannot be considered 

probative evidence, regardless of whether there is no objection. „[A] claim will not stand 

or fall on the mere ipse dixit of a credentialed witness.‟” City of San Antonio v. Pollock, 

284 S.W.3d 809, 818 (Tex 2009).
7

There are three methodologies for determining fair market value: (1) comparable 

sales, (2) actual costs and (3) income production. City of Harlingen v. Estate of 

Sharboneau, 48 S.W.3d 177, 182 (Tex. 2009). In a comparable sales approach, the 

appraiser finds data for sales of similar properties and makes upward or downward 

adjustments to the sales prices based on differences in the subject property. Id. When 

comparable sales figures are lacking or the method is otherwise inadequate as a 

measure of fair market value, courts have accepted testimony based on the cost 

approach. Id. at 183. The cost approach, which looks to replacement cost, is best 

suited for valuing improved property that is unique in character and not frequently 

exchanged on the marketplace. Religious of the Sacred Heart v. City of Houston, 836 

S.W.2d 606, 616 (Tex. 1992). While the cost method takes the property‟s depreciation 

into account, it still “tends to set the upper limit of true market value.” Estate of 

Sharboneau, 48 S.W.3d at 183. The income approach is appropriate when the property 

would, in the open market, be priced according to the income that it already generates. 

Id. An appraisal method is only valid if it produces an amount a willing buyer would 

actually pay to a willing seller. Id. 

Real estate appraiser, Travis Lowe, testified as an expert for Megan and Keith. 

His appraisal experience dates back to 1983 and in 1991, he became a state certified 

general appraiser which certified him to appraise any kind of real property. He was 

hired to appraise the north tract with and without the barn. He testified he made a 

physical inspection of the property, studied the floor plan, took photographs, conducted 

research and applied the appropriate methodologies to formulate his opinion. He 
8

described the barn as having a concrete slab, kitchen, bathroom, electricity, plumbing, 

stalls and a round pen.

Lowe testified he analyzed the highest and best use of the north tract to be 

agricultural or recreational. He used the comparable sales method to value the eightyacre north tract without the barn. He compared the north tract to four properties all 

located in Donley County and based on his summaries, determined the fair market 

value of the north tract to be $72,000.

The first comparable property he looked at was a 79.96-acre tract near the north 

tract which sold in 2009 for $64,000. It did not have a well or electricity so adjustments 

were made. The second comparable property was a tract of 631 acres which sold in 

2008 for $757,860. Part of the tract was on a river bed and had a live spring-fed pond. 

He explained live water increases the value of the land so he made downward 

adjustments based on this property. The third comparable property was a 160-acre 

tract that sold in 2007 for $825 an acre. It had poor fences and a non-functioning 

windmill so a slight adjustment was made. The fourth and final comparable property 

was a 360-acre tract that sold in 2008 for $360,000. It had an old barn, a well and 

adequate fences. He made a five percent downward adjustment for the well. Based on 

the comparable properties, Lowe calculated the range of the eighty-acre north tract to 

be between $68,000 and $72,000 and determined the higher figure as the fair market 

value of the unimproved land based upon the condition of the property.4

 

4Market value is “the price property will bring when offered for sale by one who desires to sell, but 

is not obliged to sell, and is bought by one who desires to buy, but is under no necessity of buying.” City 

of Harlingen v. Estate of Sharboneau, 48 S.W.3d 177, 182 (Tex. 2009).
9

Regarding the value of the north tract with the barn, Lowe testified that due to a

lack of similar properties and the newness of the barn, he applied the cost methodology. 

He was provided the construction contract and change orders to determine the actual 

cost of building the barn.

5

 He did not use a handbook or manual in determining the 

value of the barn. In his opinion, with a newer property, the actual cost is “as good as 

the data gets.” He then factored in depreciation on the two-year old barn and calculated 

the depreciated value of the improvements to be $124,018. He then added $20,000 to 

that figure for “in-place value of some of the improvements” such as preparation of the 

land, the pens and the sand added to the pens. The total amount for the improvements 

was $144,018. Adding the $72,000 value of the north tract, he determined the fair 

market value of the land with the barn to be $216,018.6

During cross-examination, Lowe was questioned on the value of the barn of 

$45,000 in the Donley County tax rolls and the bank‟s total valuation of $250,000 for 

both the north and south tracts with improvements. He testified that tax rolls are less 

reliable than a physical inspection. He could not speak to the bank‟s appraisal because 

he did not appraise the south tract or any improvements on it. He explained he did not 

apply the income approach in valuing the barn because it was vacant when he 

appraised it. Wes and Pam‟s expert, who did not testify, used a valuation that came 

from a handbook, and Lowe was unaware of whether a physical inspection of the 

property had been made.

 

5

The original contract price for the barn was $186,690.50. Megan testified that with change 

orders the final cost of the barn was $220,005.

6

In his testimony, Lowe rounded the figure down to $216,000.
10

Lowe‟s testimony established his thoroughness in appraising the north tract with 

and without improvements. His testimony was grounded in a sound evidentiary basis, 

was detailed and therefore, not conclusory. We disagree with Wes and Pam that 

Lowe‟s expert opinion was unreliable and constituted no evidence to support the jury‟s 

award for enhanced value to the north tract. Considering the evidence in the light most 

favorable to the jury‟s decision and indulging every reasonable inference that would 

support the award, we conclude the evidence is legally sufficient to support the 

judgment. Issue one is overruled.

ISSUE TWO

By issue two, Wes and Pam contend Keith and Megan waived their independent 

ground of recovery for unjust enrichment when no element of unjust enrichment was 

requested or submitted to the jury. We disagree. 

Unjust enrichment is an equitable theory of recovery where a party has obtained 

a benefit from another by fraud, duress or the taking of an undue advantage, Heldenfels 

Bros., Inc. v. City of Corpus Christi, 832 S.W.2d 39, 41 (Tex. 1992), and the receipt of 

those benefits is not governed by contract. Lone Star Steel Co. v. Scott, 759 S.W.2d 

144, 154 (Tex. App.—Texarkana 1988, writ denied). It is not a proper remedy merely 

because “it might appear expedient or generally fair that some recompense be afforded 

for an unfortunate loss . . . .” Heldenfels Bros., Inc., 832 S.W.2d at 42.

In her pleadings, Megan alleged unjust enrichment if Wes and Pam retained the 

full value of the improvement without repayment. Megan had the burden to present 

evidence on the elements of her claim. Ramos v. Frito-Lay, Inc., 784 S.W.2d 667, 668
11

(Tex. 1990). Question No. 3 of the charge asked the jury to determine “what 

enhancement, if any, in the market value of the North Tract was caused by the 

construction of permanent improvements by Keith or Megan Mason?” (Emphasis 

added.) Wes and Pam objected to submission of the question on the ground there was 

no evidence of enhanced value without Lowe‟s expert testimony.7 The objection was 

overruled and the jury answered $90,000.

Wes and Pam, relying on Rule 279 of the Texas Rules of Civil Procedure and 

other authorities, argue Keith and Megan waived unjust enrichment as a theory of 

recovery by failing to ask the jury a liability question or give a clarifying instruction. 

While we agree with Wes and Pam that failure to submit or request an entire ground of 

recovery from the charge can lead to procedural default, that is not the situation before 

us. Ramos, 784 S.W.2d at 668. An entire theory of recovery is not waived where the 

charge omits issues out of a cluster of issues necessary to support the theory. Turner, 

Collie & Braden, Inc. v. Brookhollow, 642 S.W.2d 160, 165 (Tex. 1982). In that 

situation, the parties waive a jury trial on the unsubmitted elements thereby submitting 

them to the trial court for resolution. First State Bank, Morton v. Chesshir, 634 S.W.2d 

742, 747 (Tex. App.—Amarillo 1982, writ ref‟d n.r.e.). Without written findings on the 

omitted elements, the trial court is presumed to have decided the omitted issues to 

support the judgment rendered. Id. 

The jury was asked to determine the value of the enhancement to the north tract

after finding Wes and Pam did not make a parol gift of the tract nor commit fraud 

 

7We have determined that Lowe‟s testimony was reliable and therefore competent evidence to 

support the jury‟s award.
12

against Keith and Megan. Wes and Pam testified they knew Megan intended to 

construct a barn on the north tract for her and Keith to run a horse training facility. Pam 

had accompanied Megan to two banks seeking loans for the project and knew Megan 

was turned down because the land was not in her name. Wes and Pam acknowledged 

the barn was paid for by Megan with a loan secured by Megan‟s mother‟s certificate of 

deposit. Megan also continued to pay the utilities for the barn, despite being prohibited 

from entering the north tract or using the barn she paid to have built. There was also 

testimony that Megan kept current with her loan payments to the bank.

Although the jury did not find Wes and Pam committed fraud or exercised duress, 

there is sufficient evidence that Wes and Pam took undue advantage of Megan by 

allowing her to build a permanent improvement on property they never intended to deed 

to her and then subsequently, locked her out. The improvements paid for by Megan led 

to enhancement of the north tract and a substantial benefit to Wes and Pam. We 

conclude the omitted elements are deemed found against Wes and Pam because there 

is evidence to support they obtained a benefit by taking undue advantage of Megan. 

We also find the trial court presumed to decide the omitted elements in support of the 

judgment. Issue two is overruled.

ISSUE FOUR

By their fourth issue in their original and reply briefs, Wes and Pam contend Keith 

and Megan are not entitled to recover prejudgment interest when they did not plead for 

it, or alternatively, the prejudgment interest was incorrectly calculated. Additionally, they 

assert prejudgment interest should not have been awarded because Keith and Megan‟s
13

post-verdict request for prejudgment interest was not granted nor ruled upon. We 

disagree that prejudgment interest was not recoverable, but agree it was incorrectly 

calculated.

As a general rule, a plaintiff is required to plead for prejudgment interest sought 

at common law as an element of damages, whereas statutory or contractual interest 

may be predicated on a prayer for general relief. See Republic National Bank v. 

Northwest National Bank, 578 S.W.2d 109, 116-17 (Tex. 1978). Pleadings may be 

amended post-verdict to allow prejudgment interest. See Benavides v. Isles Constr. 

Co., 726 S.W.2d 23, 26 (Tex. 1987). A trial court‟s refusal to allow a post-verdict 

amendment for prejudgment interest has been held to be an abuse of discretion. Id. 

Allowance of a post-verdict amendment seeking prejudgment interest does not work a 

surprise or prejudice as a matter of law. Firefighters’ & Police Officers’ Civil Serv. 

Comm’n v. Herrera, 981 S.W.2d 728, 734-735 (Tex. App.—Houston 1998, pet. denied) 

(citing Benavides, 726 S.W.2d at 26).

On June 22, 2011, Keith and Megan filed a post-verdict motion adding a claim for 

prejudgment interest. The trial court‟s judgment signed on October 5, 2011, recites that 

Keith and Megan have and recover from Wes and Pam prejudgment interest at the rate 

of five percent per annum in the amount of $8,593.15. The trial court‟s award of 

prejudgment interest is an implicit ruling granting Keith and Megan‟s motion. See TEX.

R. APP. P. 33.1(a)(2)(A). See also In re Commitment of Hill, 334 S.W.3d 226, 229 (Tex. 

2011). We conclude Keith and Megan are entitled to recover prejudgment interest.
14

We now turn to Wes and Pam‟s alternative argument that prejudgment interest 

was incorrectly calculated. Prejudgment interest accrues on the amount of a judgment 

during the period beginning on the earlier of the 180th day after the date the defendant 

receives written notice of a claim or the date suit was filed and ends on the day 

preceding the date judgment was rendered. TEX. FIN. CODE ANN. § 304.104 (West 

2006). The interest rate is five percent a year. Id. at § 304.003(c)(2). Megan made her 

claim for unjust enrichment on November 30, 2009, in her original answer, cross-claim 

and third-party claim, and judgment was rendered on October 5, 2011. The trial court‟s 

judgment provides for prejudgment interest in the amount of $8,593.15. 

Calculating from the earlier date of November 30, 2009, to October 4, 2011, the 

day preceding the date judgment was rendered, Keith and Megan are owed 

prejudgment interest for 673 days. The $90,000 award times five percent yields $4,500 

per year divided by 365 days a year resulting in $12.3287 per diem. That amount times 

673 days results in prejudgment interest rounded up to $8,297.26. We conclude the 

amount of prejudgment interest in the judgment must be reduced by $295.89. We 

modify the award of prejudgment interest to reflect Keith and Megan are entitled to 

prejudgment interest of $8,297.26.

8

 Issue four is overruled in part and sustained in part.

CONCLUSION

Accordingly, based on Keith and Megan‟s concession to issue three, the trial 

court‟s judgment is modified to delete the award of attorney‟s fees. The trial court‟s 

 

8

Post judgment interest begins to accrue from the date the original judgment is entered, i.e., 

October 5, 2011. See Phillips v. Bramlett, 407 S.W.3d 229, 239 (Tex. 2013).
15

judgment is also modified to decrease the award of prejudgment interest to $8,297.26. 

In all other respects, the trial court‟s judgment is affirmed.
