What a Chapter 42 appeal actually is
A Chapter 42 appeal is a trial de novo in state district court. The district court does not sit as an appellate body reviewing the ARB record for error; it tries the value of the property anew, as if the ARB hearing had never happened. Tex. Tax Code § 42.23(a). The property owner has the right to a jury trial. § 42.23(b).
The defendant is the appraisal district — not the taxing units, not the ARB, and not the chief appraiser. The proper plaintiff is the property owner or, in some circumstances, a lessee contractually obligated to pay the tax. § 42.015.
Who can appeal, and from what
An owner may appeal an ARB order that:
- determines a protest under § 41.41 (market value, unequal appraisal, exemption, situs, ownership, and related grounds);
- determines a motion to correct under § 25.25; or
- denies a request to enter into a settlement.
The grounds available in the lawsuit are bounded by the grounds raised at the ARB. An owner who protested only market value generally cannot add unequal appraisal in district court — although the firm routinely preserves both grounds at the administrative stage precisely to keep both available.
The lifecycle of a typical case
1. Petition
Suit is initiated by filing an original petition in district court in the county where the ARB sits, naming the appraisal district as defendant, within the 60-day jurisdictional window. § 42.21(a).
2. Prepayment of taxes
To keep jurisdiction alive, the owner must timely pay the undisputed portion of the tax — generally the lesser of the amount not in dispute or the amount due on the prior year's value. § 42.08. Failing to comply forfeits the right to a final determination.
3. Discovery and valuation evidence
Discovery proceeds under the Texas Rules of Civil Procedure. The decisive evidence in most cases is expert appraisal testimony: income capitalization for income-producing property, cost approach for special-use property, and a sales-comparison approach where market data supports it. For unequal appraisal claims, the owner develops a sample of comparable properties and applies the statutory median-of-comparables formula. § 42.26(a)(3).
4. Mediation
Most Texas appraisal districts mediate Chapter 42 cases. A well-developed appraisal and a credible unequal-appraisal sample are usually what move the district to a meaningful settlement.
5. Trial
If the case does not settle, it is tried to the bench or a jury. Judgment establishes the appraised value for the tax year, and the appraisal roll is corrected. §§ 42.41–42.43. The owner is entitled to a refund of any overpayment, with interest. § 42.43.
Attorney's fees
Texas Tax Code § 42.29 authorizes attorney's fees to a prevailing property owner, capped at the greater of $15,000 or 20% of the total tax reduction, not to exceed the lesser of $100,000 or the total tax reduction. The availability of statutory fees is one of the levers that makes serious litigation economic on individual commercial properties.
The Chapter 42 appeal is a lawsuit, not an administrative proceeding. Treating it as a lawsuit from day one — pleadings, experts, discovery, trial — is what separates effective representation from extended ARB-style negotiation.
