(a)Except as provided by Subsection (i), in any action or arbitration proceeding for damages arising out of the provision of professional services by a licensed or registered professional, a claimant shall be required to file with the complaint an affidavit of a third-party licensed architect, licensed professional engineer, registered landscape architect, or registered professional land surveyor who:
(1)is competent to testify;
(2)holds the same professional license or registration as the defendant; and
(3)practices in the area of practice of the defendant and offers testimony based on the person's:
(A)knowledge;
(B)skill;
(C)experience;
(D)education;
(E)training; and
(F)practice.
(b)The affidavit shall set forth specifically for each theory of recovery for which damages are sought, the negligence, if any, or other action, error, or omission of the licensed or registered professional in providing the professional service, including any error or omission in providing advice, judgment, opinion, or a similar professional skill claimed to exist and the factual basis for each such claim. The third-party licensed architect, licensed professional engineer, registered landscape architect, or registered professional land surveyor shall be licensed or registered in this state and actively engaged in the practice of architecture, engineering, or surveying.
(c)The contemporaneous filing requirement of Subsection (a) shall not apply to any case in which the period of limitation will expire within 10 days of the date of filing and, because of such time constraints, a claimant has alleged that an affidavit of a third- party licensed architect, licensed professional engineer, registered landscape architect, or registered professional land surveyor could not be prepared. In such cases, the claimant shall have 30 days after the filing of the complaint to supplement the pleadings with the affidavit. The trial court may, on motion, after hearing and for good cause, extend such time as it shall determine justice requires.
(d)The defendant shall not be required to file an answer to the complaint and affidavit until 30 days after the filing of such affidavit.
(e)A claimant's failure to file the affidavit in accordance with this section shall result in dismissal of the complaint against the defendant. This dismissal may be with prejudice.
(f)An order granting or denying a motion for dismissal is immediately appealable as an interlocutory order.
(g)This statute shall not be construed to extend any applicable period of limitation or repose.
(h)This statute does not apply to any suit or action for the payment of fees arising out of the provision of professional services.
(i)A third-party plaintiff that is a design-build firm or a design-build team, or an architect, engineer, or other member of a design-build firm or design-build team, is not required to file an affidavit described by Subsection (a) in connection with filing a third-party claim or cross-claim against a licensed or registered professional if the action or arbitration proceeding arises out of a design-build project in which a governmental entity contracts with a single entity to provide both design and construction services for the construction, expansion, extension, rehabilitation, alteration, or repair of a facility, a building or associated structure, a civil works project, or a highway project.

Plain-English Summary

The certificate of merit, and one of the most consequential pre-suit gates in Texas civil practice.

In any action or arbitration proceeding for damages arising out of the provision of professional services, a claimant shall be required to file with the complaint an affidavit of a third-party licensed architect, professional engineer, registered landscape architect, or registered professional land surveyor who is competent to testify, holds the same professional license or registration as the defendant, and practices in the area of practice of the defendant.

The same-license requirement is strict. An engineer’s affidavit does not support a claim against an architect, however qualified the engineer.

Subsection (b) sets what the affidavit must contain, and the standard is specific: for each theory of recovery, the negligence or other action, error, or omission, and the factual basis for each such claim. A general statement that the work fell below standard does not satisfy it. The affiant must be licensed in this state and actively engaged in practice.

Subsection (e) is the sanction: failure to file shall result in dismissal, and this dismissal may be with prejudice. The dismissal is mandatory; only its prejudice is discretionary.

Subsection (c) is the one relief valve, and it is narrow. Where limitations will expire within 10 days of filing and the affidavit could not be prepared because of that constraint, the claimant has 30 days after filing to supplement, extendable by the court on motion for good cause.

Subsection (f) makes an order granting or denying dismissal immediately appealable as an interlocutory order — so the question is resolved before the case proceeds.

Two exclusions. Subsection (g) confirms the section does not extend any limitations or repose period. Subsection (h) exempts suits for the payment of fees, and subsection (i) exempts certain design-build third-party claims on governmental projects.

Frequently Asked Questions

What is a certificate of merit in Texas?

An affidavit from a third-party professional holding the same license as the defendant, filed with the complaint, setting out the error and its factual basis for each theory of recovery.

What happens if I do not file it?

Dismissal is mandatory, and the court may make it with prejudice.

Is there any extension?

Only where limitations will expire within 10 days of filing and that constraint prevented preparation. The claimant then has 30 days, extendable for good cause.

Does it apply to a fee dispute?

No. Subsection (h) exempts suits for the payment of fees arising out of professional services.

Can the ruling be appealed immediately?

Yes. An order granting or denying dismissal is immediately appealable as an interlocutory order.
