What Is Perjury Under Missouri Law?

Perjury is a Class D felony under Missouri law — a knowingly false sworn statement made in an official proceeding that can carry up to seven years in prison and a permanent felony record. To prove perjury under § 575.040 RSMo, the prosecution must establish that you made a false statement under oath, in an official proceeding, about a material fact, and that you knew the statement was false when you made it. Missouri also criminalizes false declarations under § 575.050 RSMo — written sworn statements submitted outside of court, such as affidavits and government filings. Both are Class D felonies.

Perjury is defined in Missouri criminal statutes under § 575.040 RSMo as knowingly making a false statement under oath in an official proceeding about a material fact. The statute is precise about what it covers — and that precision matters for your defense.

To be guilty of perjury, all four elements must be present: the statement had to be made under oath or affirmation; it had to be made in an official proceeding (a trial, deposition, grand jury hearing, or similar formal legal setting); you had to know it was false when you made it; and the statement had to concern something material — a fact capable of affecting the outcome of the proceeding.

Perjury is a Class D felony in Missouri, carrying a potential prison sentence of up to seven years and fines of up to $10,000. Beyond the sentence, a felony conviction brings lasting consequences: loss of professional licenses, disqualification from government employment, and a permanent criminal record that follows you for years.

The single most important word in Missouri's perjury statute is "knowingly." The prosecution must prove you knew the statement was false when you made it — not just that it turned out to be incorrect. Memory lapses, genuine confusion, and honest mistakes are not perjury. If there is a credible explanation for why you believed what you said was true, that goes directly to defeating the charge.

Context

Where Do Perjury Charges Come From in Missouri?

Perjury charges can arise in more settings than most people realize. The common thread is a sworn statement — any time you are placed under oath and make a statement that later turns out to be provably false, the door to a perjury charge opens. Here are the most common contexts where these charges originate.

1
Courtroom testimony — civil and criminal cases The most obvious setting. Any witness who testifies under oath in a trial, whether as a party or a third-party witness, is subject to perjury laws if they knowingly make false statements about material facts. Both civil and criminal trials carry the same exposure.
2
Depositions In civil litigation, depositions are sworn proceedings. Witnesses and parties testify under oath before a court reporter, and that testimony is treated exactly like in-court testimony for perjury purposes. Many people don't fully appreciate this — a deposition is a formal legal proceeding.
3
Grand jury testimony Grand jury proceedings are closed to the public and take place without a judge in the room, but witnesses testify under oath. False statements made to a grand jury fall squarely within Missouri's perjury statute.
4
Sworn affidavits and court filings This is where many unrepresented people get into trouble. When you sign a document that contains the phrase "under penalty of perjury" or that includes a notarized oath, you are making a sworn statement — even if you are sitting at home or in an office, not in a courtroom. False statements in affidavits, verified petitions, and sworn court filings can result in charges under § 575.050 RSMo (making a false declaration), which carries the same felony exposure as perjury itself.
5
Sworn law enforcement interviews and statements A routine police interview, by itself, does not create perjury exposure because it is not an "official proceeding" under the statute. However, if you sign a sworn statement or give testimony before a magistrate or grand jury as part of a law enforcement investigation, that sworn testimony can be subject to perjury charges. Additionally, making a knowingly false report to law enforcement — sworn or not — can result in charges under § 575.080 RSMo.
6
Applications and government forms Many government applications — for professional licenses, benefits, or court-related processes — are signed under penalty of perjury. Knowingly providing false information on these forms creates exposure under § 575.050 RSMo, even though the statement is not made in a live proceeding.
Elements of the charge

What the Prosecution Must Prove

To convict someone of perjury under § 575.040 RSMo, the prosecution must prove every element of the offense beyond a reasonable doubt. Understanding each element is the foundation of any effective defense. If the prosecution cannot prove even one element, the charge should not result in a conviction.

📋
Element 1: Statement Made Under Oath
The prosecution must prove the defendant was placed under oath or affirmation before making the statement. If the statement was not sworn — or if there is a question about whether the oath was properly administered — that is a potential weakness in the state's case.
Element 2: The Statement Was False
The prosecution must establish that the statement was objectively false. This often involves pulling transcripts, records, and other evidence to compare what was said against what the record shows. Context matters — an incomplete answer is not the same as a false one.
🧠
Element 3: The Defendant Knew It Was False (Willfulness)
This is the most contested element in most perjury cases. The prosecution must prove the defendant knew the statement was false at the moment they made it. Misremembering, confusion, or a genuine belief that the statement was accurate defeats this element entirely. An honest mistake — even a significant one — is not perjury under Missouri law.
⚖️
Element 4: Materiality
The false statement must have concerned a material matter — one capable of influencing the outcome of the proceeding. If the statement was about something inconsequential that had no bearing on the result, the materiality element may not be satisfied. This is a separate and independently challengeable element of the charge.
Defense strategy

How Chris Defends Perjury Charges in Missouri

Chris Miller is a Missouri criminal defense attorney who has been licensed since 2012 and represents clients facing criminal charges across central Missouri. Before building Bur Oak Legal, he worked as a government attorney inside Missouri's own legal system — experience that gave him direct insight into how the state builds and evaluates cases. That background matters when the defense depends on picking apart exactly what the record shows.

Perjury cases live and die on the documentary record. The first thing Chris does in any perjury case is pull the complete transcript or recording of what was actually said — because the charge almost always hinges on what the words meant in context, not just what they looked like in isolation. A statement that appears false at first reading may be a misstatement, a miscommunication, or an incomplete answer that the questioner did not follow up on.

The Honest Mistake Defense

The most common defense in perjury cases is also the most legally sound: you made an honest mistake, not a willful lie. Memory is not a recording. People misremember dates, confuse sequences of events, and describe situations through their own imperfect perception. If there is any credible basis for concluding you believed what you said was true — inconsistent prior statements, a demonstrated pattern of confusion about the facts, evidence you did not have complete information — Chris will develop that evidence and put it before the court or jury.

The prosecution has to prove you knew the statement was false at the moment you made it. That is a high standard, and it is one that many perjury cases fail to meet when the defense is properly built.

The Materiality Defense

Even if the prosecution can prove a false statement was made knowingly, the statement must have been about a material fact — something that could have changed the outcome of the proceeding. If the false statement was about a peripheral detail that had no bearing on the court's decision, the materiality element is vulnerable. Chris reviews the record of the proceeding to assess whether the statement at issue was truly material, or whether it concerned something that the court or decision-maker did not, and would not, have relied upon.

Challenging the Record

Transcripts are imperfect documents. Court reporters sometimes mis-transcribe testimony. Audio recordings sometimes capture ambiguous statements that are interpreted differently in different contexts. Depositions sometimes reflect questions that were poorly framed, leading to answers that appear inconsistent but actually reflect a reasonable interpretation of an ambiguous question. Chris reviews the original record carefully — and when there is any question about the accuracy of the transcript or the meaning of the words as spoken, he pursues that challenge.

Who Faces These Charges

Perjury and false statement charges in Missouri often arise from situations where the person charged did not fully understand what they were agreeing to when they signed a document or took an oath. Many people facing false declaration charges under § 575.050 RSMo had no idea the document they signed was considered a sworn statement under Missouri law. Others testify at a deposition without fully grasping that the proceeding carries the same legal weight as in-court testimony.

Understanding what actually happened — the context, the pressure, the information you had at the time — is essential to building a defense. These cases are not just about whether a statement was technically false. They are about whether you intentionally lied, or whether you did the best you could with an imperfect understanding of a complex situation.

Know the distinction

Perjury vs. Making a False Declaration: Key Differences

Missouri law draws a meaningful distinction between perjury under § 575.040 RSMo and making a false declaration under § 575.050 RSMo. Both are Class D felonies, but they apply in different situations — and understanding the difference matters for your defense.

§ 575.040 RSMo
Perjury
Requires a statement made under oath in an official proceeding — a trial, deposition, grand jury, or similar formal legal process. The oath must be properly administered, and the proceeding must qualify as "official" under Missouri law. Applies to live testimony in recognized legal settings.
§ 575.050 RSMo
Making a False Declaration
Does not require a live proceeding. Covers any false written statement made under penalty of perjury — sworn affidavits, verified petitions, declarations filed with courts or government agencies. If you signed a document with a sworn declaration clause and provided false information, this statute applies regardless of whether you appeared in court.

The practical significance: many people face false declaration charges because they signed a document — a court filing, a petition, a government form — without realizing it contained a sworn declaration. The document may not have had the word "oath" anywhere on it. It may have been presented to them quickly, in a stressful situation, without a full explanation of what they were affirming. That context does not eliminate the charge, but it is directly relevant to whether they acted "knowingly" — and it is exactly the kind of circumstance that a defense attorney needs to develop.

Common questions

Frequently Asked Questions About Perjury in Missouri

Under Missouri law, perjury is defined in § 575.040 RSMo as knowingly making a false statement under oath in an official proceeding about a material fact. To be perjury, the statement must have been made under oath or affirmation, the person must have known it was false when they made it, and the false statement must have been about something material — meaning it could affect the outcome of the proceeding. Perjury is a Class D felony in Missouri, which carries a potential prison sentence of up to seven years.
To convict someone of perjury under § 575.040 RSMo, the prosecution must prove four things beyond a reasonable doubt: (1) the defendant made a statement under oath or affirmation in an official proceeding; (2) the statement was false; (3) the defendant knew the statement was false at the time they made it — this is the willfulness or "knowingly" element; and (4) the false statement concerned a material matter, meaning it was capable of influencing the outcome of the proceeding. If the prosecution cannot prove any one of these elements, the perjury charge should not result in a conviction.
No. An honest mistake is not perjury under Missouri law. Perjury requires that you knowingly made a false statement — meaning you knew it was untrue when you said it. If you were confused, misremembered a fact, or genuinely believed what you said was accurate at the time, that is a complete defense to a perjury charge. Memory is imperfect, and courts have long recognized that. The prosecution bears the burden of proving beyond a reasonable doubt that you knew the statement was false when you made it. Showing that you had a good-faith belief the statement was true defeats the knowingly element.
Generally, perjury under § 575.040 RSMo requires a statement made under oath in an official proceeding — a routine police interview does not meet that standard. However, if you gave a sworn statement to law enforcement, signed an affidavit, or testified before a grand jury, those statements can be subject to perjury charges. Separately, making a knowingly false report to law enforcement — even without an oath — can result in charges under § 575.080 RSMo. The safest approach is to speak with an attorney before making any formal statement to law enforcement.
Perjury under § 575.040 RSMo applies to false statements made under oath in an official proceeding — courtroom testimony, depositions, grand jury appearances. Making a false declaration under § 575.050 RSMo covers false written statements made under penalty of perjury — sworn affidavits, applications, and forms submitted to courts or government agencies. The key difference: a false declaration does not require that the statement be made in a live proceeding. Both are Class D felonies in Missouri. Many people face false declaration charges because they didn't realize a document they signed was sworn under penalty of perjury.
Perjury under § 575.040 RSMo is a Class D felony in Missouri. A Class D felony conviction carries a potential prison sentence of up to seven years and fines of up to $10,000. Beyond the sentence itself, a felony conviction brings serious long-term consequences: loss of voting rights while incarcerated, potential loss of professional licenses, disqualification from certain government jobs, and a permanent felony record. Making a false declaration under § 575.050 RSMo and making a false report under § 575.080 RSMo carry their own felony or misdemeanor exposure depending on the specific circumstances.
