Perjury
What happens when a person falsely testifies in the court?
A knowingly false, material statement made under a lawful oath or a declaration permitted under penalty of perjury can lead to a felony perjury charge. A disputed answer alone does not establish those elements.
Under Penal Code § 118, a materially false statement can be perjury when made under a lawful oath or in a declaration permitted under penalty of perjury, if the speaker willfully presents it as true while knowing it is false. The prosecution must identify the particular words, the material issue and proof of knowledge. A mistake, an unsworn form or an inaccurate memory is not automatically perjury. A teacher application or DMV form can raise a perjury question only after examining its actual certification, the law allowing that declaration, materiality and the evidence of what the signer knew; the form title alone does not decide the charge.
Perjury is a felony allegation, but custody, probation, fines and later record relief depend on the filed charge, the applicable law and the case disposition. A first offense does not itself require probation or guarantee avoidance of custody. The firm can review the exact statement, complete record and next court notice before discussing available defenses or consequences.
What the perjury allegation must identify
A disputed answer is not automatically perjury. Under Penal Code § 118 and California’s 2026 jury instruction No. 2640, the prosecution must identify the particular statement, a lawful oath or permitted statement under penalty of perjury, a material issue, and proof that the speaker willfully presented as true something they knew was false. A memory error, ambiguous question, inaccurate estimate or later-discovered mistake calls for a different analysis from a knowingly false material answer. The materiality question is tied to the purpose of the particular proceeding or required form; a court statement and an administrative declaration cannot safely be assessed from a generic example.
For a signed declaration, deposition or certificate, the jury instruction can also require proof that the person signed and delivered it intending circulation or publication as true. That makes the exact document, signature page, submission method and date relevant. A draft never submitted and a final sworn filing should not be treated as the same event. The instruction also requires evidence of falsity beyond a single contradicting witness in the circumstances it describes; that rule does not make every two-witness dispute a defense. Counsel should review the actual evidence rather than count accusers.
Build a record around the statement, not a general denial
Start with the filed count and the precise words the government says were false. Keep the complete transcript or recording, the question immediately before the answer, exhibits shown to the speaker, and every version of a form or declaration. For an electronic submission, preserve the confirmation, version history and any instructions attached to the form.
Dates matter: a fact learned after signing does not establish what someone knew when they spoke. Earlier messages, business records or calendar entries may clarify what the person reasonably understood at that moment. Give counsel the unfavorable records too; selective excerpts can distort both the accusation and the defense.
If the statement was corrected later, preserve the original and the correction with their dates. A correction does not erase a filed charge, but the jury instruction recognizes that it can bear on intent in an appropriate case. Do not alter an original document, ask a witness to change an account, or assume a conversation with the investigator replaces a court response. The next hearing notice and the complaint control immediate steps.
Perjury is charged as a felony; punishment, any probation question and later record relief depend on the actual case and governing law, not a first-offense promise.
Questions to bring to a consultation
Was the statement actually sworn or made under penalty of perjury? Ask for the exact oath, declaration text or authorized filing process. A false statement may create another problem without satisfying this charge.
Which fact was material, and what proves it was knowingly false? Compare the full question, available information at the time and independent records. A lawyer can test each element and explain what evidence must be obtained through the criminal discovery process.
