What is aggravated perjury under § 37.03?
Texas Penal Code § 37.03 defines aggravated perjury as perjury (a false statement under oath, made with intent to deceive) that is made during or in connection with an official proceeding and is material. It is a third-degree felony — 2 to 10 years in prison and a fine up to $10,000.
Aggravated perjury is the felony tier of Texas's perjury scheme. Under Penal Code § 37.03, a person commits the offense if they commit perjury as defined in § 37.02 and the false statement (1) is made during or in connection with an official proceeding and (2) is material. The statute then states plainly that the offense is a felony of the third degree. The Texas Court of Criminal Appeals has tracked that text directly, noting that "an offense under this section is a felony of the third degree." State v. Rosenbaum, 910 S.W.2d 934, 948 (Tex. Crim. App. 1995).
The underlying perjury element does real work. Section 37.02 requires that, with intent to deceive and with knowledge of the statement's meaning, the accused made a false statement under oath (or swore to the truth of a previously made false statement) when the statement was required or authorized by law to be made under oath. So the felony has a stack of mental-state and procedural requirements baked in before you ever reach the "official proceeding" and "material" aggravators. A Texas appellate court summarized the whole picture this way: a person commits aggravated perjury if, "with intent to deceive and with knowledge of the statement's meaning, he or she makes a false statement under oath in connection with an official proceeding, and the false statement is material." Steen v. State, 78 S.W.3d 516, 522 (Tex. App.—Houston [14th Dist.] 2002, pet. ref'd).
One practical point worth flagging at the top: aggravated perjury is a process crime. It almost always grows out of some other case — a divorce, a CPS investigation, a grand jury, a civil deposition, a probation-revocation hearing — where someone testified or signed a sworn document. That origin shapes both the defense and the risk, because the "evidence" is usually a transcript or a signed affidavit that already exists. This page covers aggravated perjury under § 37.03; the misdemeanor offense of simple perjury under § 37.02 is a separate topic.
What is the punishment for aggravated perjury?
Aggravated perjury is a third-degree felony under § 37.03, punishable by 2 to 10 years in the Texas Department of Criminal Justice and a fine up to $10,000 under § 12.34. A prior felony conviction can raise the range under § 12.42; two priors trigger the habitual range of 25 to 99 years or life.
Aggravated perjury is a third-degree felony. The numbers below come straight from the Penal Code's punishment chapter, not from any prediction about a particular case. The gap between the felony and the misdemeanor is the entire fight in many cases — the difference between up to a decade in prison and a year in county jail is whether the State can establish the two aggravating elements.
- Third-degree felony range — § 12.34
- Conviction carries 2 to 10 years in the Texas Department of Criminal Justice and a fine not to exceed $10,000 under § 12.34. Community supervision (probation) and, in appropriate cases, deferred adjudication may be available depending on the disposition and the defendant's history.
- Contrast: simple perjury — § 37.02
- Without the official-proceeding and materiality aggravators, the offense is simple perjury under § 37.02 — a Class A misdemeanor punishable by up to one year in county jail and a fine up to $4,000. Reducing a felony to this misdemeanor is a central defense objective.
- Enhancement with prior felonies — § 12.42
- A single prior felony conviction enhances a third-degree felony to the second-degree range (2 to 20 years) under § 12.42(a); two sequential prior felony convictions trigger the habitual range of 25 to 99 years or life under § 12.42(d).
Because materiality and the "official proceeding" predicate are the elements that create the felony, a defense lawyer attacks those before ever arguing about whether the statement was false at all. Knocking out either aggravator does not merely reduce the sentence within the felony range — it changes the offense itself to a misdemeanor.
What must the State prove?
To convict, the State must prove a false statement, made under a lawful oath, with intent to deceive and knowledge of the statement's meaning, during or in connection with an official proceeding, that was material. Every line is a separate place to win.
To obtain an aggravated-perjury conviction, the State must prove each of the following beyond a reasonable doubt. Treat every line as a separate place to win.
- A false statement
- The statement must actually be false. An ambiguous answer, a literally true but misleading answer, or a statement the witness genuinely believed at the time can all fail this element.
- Under oath, where required or authorized by law
- The statement must have been made under a lawful oath. A defective oath, an unauthorized notary, or a setting where no oath was legally required undercuts the perjury element entirely.
- With intent to deceive and knowledge of the statement's meaning
- This is the culpable mental state. Confusion, mistake, faulty memory, or a misunderstanding of the question negates intent to deceive. Steen, 78 S.W.3d at 522, lists intent to deceive and knowledge of meaning as core requirements.
- Made during or in connection with an official proceeding
- This is the first felony-specific element. If the statement was not tied to a qualifying official proceeding, the offense is misdemeanor perjury, not aggravated perjury.
- Material
- The statement must have been capable of affecting the course or outcome of the proceeding. This is decided by the judge as a question of law — and it is the most contested element in practice.
Why materiality is the whole ballgame
Materiality separates a felony from a misdemeanor, and Texas treats it as a question of law for the judge under § 37.04(c). A statement is material if it could have affected the course or outcome of the proceeding; trivial falsifications are excluded. That makes a legal challenge to materiality the most important tool in the case.
Materiality is what separates a felony from a misdemeanor, and Texas treats it differently from almost every other element. Under § 37.04(a), "a statement is material, regardless of the admissibility of the statement under the rules of evidence, if it could have affected the course or outcome of the official proceeding." The standard is capability, not actual effect. As the Houston court put it, "the State is not required to prove that a false statement did, in fact, affect the outcome of the hearing" — it need only show the statement, if believed, "could have affected the course or outcome of the proceeding." Steen, 78 S.W.3d at 523.
There is an outer limit, though, and it favors the defense. The same court explained that "materiality refers to statements having some substantial potential for obstructing justice and excludes utterly trivial falsifications." Id. A lie about something that genuinely could not have moved the needle — a collateral detail with no bearing on any issue before the tribunal — is not material, and therefore is not aggravated perjury.
The procedural twist is the part most people miss: materiality is a question of law for the judge, not a fact for the jury. Section 37.04(c) provides that "whether a statement is material in a given factual situation is a question of law." The Court of Criminal Appeals has confirmed exactly that, quoting the statute that "whether a statement is material in a given factual situation is a question of law." Rosenbaum, 910 S.W.2d at 936. Because the judge decides it, the defense can brief and argue materiality as a legal matter — frame the issue, marshal the record, and ask the court to rule the statement immaterial as a matter of law.
One caution from the same case sets the timing. In Rosenbaum, the court held that a defendant cannot use a pretrial motion to force the trial court to weigh the sufficiency of the evidence on an element like materiality before trial; a facially valid indictment must go to trial on the merits. Id. at 948. The practical lesson is to litigate materiality as a legal question on a developed record — at trial, in a properly framed motion, or through jury-charge and directed-verdict arguments — rather than as a disguised pretrial sufficiency challenge.
What counts as an "official proceeding"?
Section 37.01 defines an official proceeding broadly as any administrative, executive, legislative, or judicial proceeding that may be conducted before a public servant authorized to take statements under oath. That reaches grand juries, trials, depositions, hearings, and many sworn government filings — but a statement outside a qualifying proceeding supports only misdemeanor perjury.
The second felony element is the "official proceeding" predicate. The definition in § 37.01 is broad: an official proceeding is any type of administrative, executive, legislative, or judicial proceeding that may be conducted before a public servant authorized by law to take statements under oath. That sweeps in grand jury sessions, trials, depositions in pending litigation, contested administrative hearings, and many sworn government filings.
Breadth cuts both ways. A statement made in a casual setting, in a document that did not require an oath, or in a context that is not a "proceeding" at all may support — at most — misdemeanor perjury rather than the felony. A common defense theory is that the statement, even if false and even if sworn, was not made "during or in connection with" a qualifying official proceeding. The phrase "in connection with" can be litigated: how close must the statement be to the proceeding, and was the document or testimony actually part of it? These are fact-bound questions where the precise posture of the underlying case matters.
Can a retraction defeat the charge?
Yes, within a narrow window. Section 37.05 makes retraction a defense if the false statement is taken back before the testimony is complete and before it became manifest that the falsity would be exposed. A late or exposure-forced "retraction" does not qualify.
Yes — within a narrow window. Section 37.05 creates an affirmative retraction defense. As one Texas court described it, it is a defense to prosecution under § 37.03 that the actor retracted the false statement "(1) before completion of the testimony at the official proceeding; and (2) before it became manifest that the falsity of the statement would be exposed." Harris v. State, No. 01-08-00261-CR (Tex. App.—Houston [1st Dist.] Dec. 17, 2009, no pet.) (mem. op.) (quoting Tex. Penal Code § 37.05).
Both conditions matter. A retraction that comes after the testimony is complete is too late. So is a "retraction" offered only once it is obvious the lie is about to be caught — say, after the opposing party produces the document that proves the statement false. The defense rewards a witness who corrects the record promptly and voluntarily, not one who waits until exposure is imminent. Because the window closes quickly, anyone who realizes they gave a false answer in a live proceeding should ask a defense lawyer about retraction immediately, before the hearing ends.
The two-witness and inconsistent-statement rules
Two corroboration rules protect the accused. Under Code Crim. Proc. art. 38.18, no one may be convicted on the uncorroborated testimony of a single witness to the falsity. Under § 37.06, proof that two sworn statements conflict does not, by itself, prove which one was false.
Texas builds extra protection into perjury prosecutions, and both rules are defense tools. First, Code of Criminal Procedure Article 38.18 provides that no person may be convicted of perjury or aggravated perjury solely on the testimony of one witness to the falsity of the statement. There must be corroboration — the historical "two-witness rule." If the State's proof of falsity rests on a single uncorroborated witness, the conviction cannot stand.
Second, § 37.06 governs inconsistent statements. When a prosecution is based on the theory that the accused made two materially inconsistent sworn statements, proof that the two statements contradict each other is not, by itself, proof of which one was false. The State still has to prove that a particular statement was the false one beyond a reasonable doubt. People sometimes assume that "you said two different things under oath" automatically equals perjury; it does not. These corroboration and inconsistency rules give the defense leverage that does not exist in an ordinary fraud or theft case.
Local DFW practice
Aggravated perjury is a felony, so cases are filed by indictment and heard in the felony district courts of the county where the underlying proceeding occurred. In DFW, perjury allegations most often arise out of family-law, CPS, grand jury, and civil-deposition matters already in a court record.
Aggravated perjury is a felony, so these cases are filed by indictment and heard in the felony district courts of the county where the underlying proceeding occurred. We defend cases across the DFW counties from our Frisco office; here is the general lay of the land.
- Collin County. Felony cases run through the district courts at the Collin County Courthouse (Russell A. Steindam Courts Building) in McKinney, with grand jury presentment for indictment. Because so many perjury allegations arise from family-law and CPS matters, the underlying civil file is often a major part of the picture.
- Dallas County. Felony aggravated-perjury cases are handled at the Frank Crowley Courts Building in Dallas. Dallas has a high volume of contested hearings and grand jury activity, which is exactly the soil from which perjury referrals grow.
- Denton County. Cases proceed through the felony district courts at the Denton County Courts Building in Denton. As elsewhere, the charged statement usually comes out of an existing case file rather than a fresh investigation.
- Tarrant County. Felony matters are centered at the Tim Curry Criminal Justice Center in Fort Worth. The same dynamics apply — the transcript or affidavit at issue is typically already in a court record.
These are general observations about how felony dockets are organized, not predictions about any prosecutor's charging decision. Local practice varies, and the specific judge, court, and underlying case all shape strategy.
When to retain counsel
Retain counsel the moment you learn sworn testimony is being questioned — before you give any further statement. Because perjury grows out of an existing case, early counsel can address materiality and retraction, sometimes before charges are filed.
The right time to retain counsel in an aggravated-perjury matter is the moment you learn that a sworn statement is being scrutinized — when a judge or opposing counsel flags testimony, when a grand jury subpoena arrives, or when an investigator makes contact. Aggravated perjury cases often grow out of an existing case — a divorce, a CPS matter, a civil deposition, a probation-revocation hearing — and anything you say or file next can become the charged statement. Early counsel can invoke the Fifth Amendment and the right to counsel, prevent further sworn statements, and analyze materiality under § 37.04 and the retraction defense under § 37.05 while the window is still open. There is sometimes a pre-charge period where the right legal posture changes whether charges are filed at all.
The wrong time to retain counsel is after additional sworn statements have been given, after the retraction window has closed, and after the transcript or affidavit has been locked in. People sometimes treat a perjury allegation as a side issue to their "real" case; in fact it is a standalone third-degree felony with prison exposure and lasting credibility and licensing consequences. The case has to be defended on its own merits, with materiality, the official-proceeding predicate, and corroboration analyzed from the outset.
