Lying on a notarized document can void the document, land you in prison, and open you up to civil lawsuits from anyone who lost money because of the lie. The notary’s seal does not shield what you wrote; it only confirms that you were the one who signed it. Once the falsehood surfaces, the fallout runs from the document itself to criminal charges, financial damages, professional discipline, and, for non-citizens, immigration consequences.
The Document Gets Thrown Out
The first thing that happens is that the document stops working. When a court finds a material falsehood in a notarized instrument, it can declare the document void and reverse whatever it was meant to accomplish. Federal court rules let a judge set aside a judgment or order obtained through fraud or misrepresentation, and the same principle reaches contracts, deeds, and affidavits.1Legal Information Institute. Federal Rules of Civil Procedure Rule 60 – Relief from a Judgment or Order
What that looks like in practice depends on the document. A property deed with a forged signature can be set aside, blocking the ownership transfer. A loan agreement built on falsified financials can be rescinded. A sworn affidavit used in a custody fight can be struck from the record and shift the outcome. Every legal consequence that flowed from the document is in play once the lie is exposed.
Criminal Charges You Could Face
The exact charge depends on what the document said and where it went. Two categories cover most cases: perjury and false statements.
Perjury
If the document contained a sworn oath or a declaration under penalty of perjury, a deliberate lie in it is perjury. That covers affidavits, sworn declarations, and anything you signed attesting the contents are true. A written declaration signed under penalty of perjury carries the same legal weight as testimony given under oath in a courtroom.2Legal Information Institute. Declaration Under Penalty of Perjury Federal law allows unsworn written declarations to stand in for sworn statements as long as the signer includes language that the contents are true “under penalty of perjury.”3Office of the Law Revision Counsel. United States Code Title 28 Section 1746 – Unsworn Declarations Under Penalty of Perjury
To convict, the government has to prove the statement was made knowingly and that it was material. A wrong date you honestly didn’t catch is not perjury. Deliberately lying about whether you witnessed an accident is. Federal perjury is a felony punishable by up to five years in prison, and nearly every state treats its own version as a felony too.
False Statements and False Filings
Even without a sworn oath, submitting a document with false information to a government body can be a separate crime. Federal law punishes anyone who knowingly makes a materially false statement, or uses a document containing false information, in any matter within federal jurisdiction, with up to five years in prison.4Office of the Law Revision Counsel. United States Code Title 18 Section 1001 – Statements or Entries Generally The statute is broad enough to sweep in false tax documents and fabricated agency forms alike.
Some false documents carry much steeper penalties. Lying on a mortgage application or any loan document tied to a federally insured financial institution is punishable by up to 30 years in prison and a fine of up to $1,000,000.5Office of the Law Revision Counsel. United States Code Title 18 Section 1014 – Loan and Credit Applications Generally Overstating income, inflating property values, or hiding debts on a mortgage application all fall inside that statute.
At the state level, filing a document with false information at a county recorder or similar public office is usually charged as filing a false instrument. It ranges from a misdemeanor to a felony depending on the jurisdiction and whether the signer intended to defraud.
What a Sentence Actually Looks Like
The statutory maximums are the ceiling, not the typical outcome. According to the U.S. Sentencing Commission’s 2024 data, the average federal prison sentence for fraud offenses was 28 months, and perjury cases averaged 18 months.6United States Sentencing Commission. 2024 Sourcebook of Federal Sentencing Statistics Cases with large financial losses or elaborate schemes produce much longer sentences.
Prison isn’t the end of it. Federal courts are required to order restitution to victims of fraud whenever there are identifiable victims with financial losses, regardless of whether the defendant can afford to pay.7GovInfo. United States Code Title 18 Section 3663A – Mandatory Restitution to Victims of Certain Crimes Courts can also impose fines and years of supervised release. A felony conviction leaves a permanent record that reaches employment, housing, voting rights, and firearm ownership in many states.
Getting Sued by Anyone You Harmed
Separate from any criminal case, anyone who lost money because of your lie can sue you for civil fraud. A conviction isn’t required. The plaintiff only has to show that you made a false statement, knew it was false, and that they relied on it and suffered a financial loss.
Take a notarized bill of sale that falsely states a car was never in an accident. The buyer pays full price, later finds frame damage, and sues to recover the gap between what they paid and the car’s real value, plus repair costs.
When the fraud was intentional, the plaintiff can also seek punitive damages on top of actual losses. Punitive damages punish the conduct rather than reimburse the loss, and most states require a higher burden of proof to get them. Where the lie was calculated and the harm was foreseeable, those awards can dwarf the compensatory damages.
One thing catches people out: the clock on a civil fraud claim often doesn’t start when you signed the document. In most jurisdictions, it begins when the victim discovered the fraud, or reasonably should have. This discovery rule means a lawsuit can show up years later. Typical limitation periods run three to six years from discovery, with wide state-to-state variation.
Professional License and Immigration Fallout
A fraud or perjury conviction causes trouble well past the sentence. Attorneys, doctors, nurses, real estate agents, accountants, and anyone else holding a state-issued license faces disciplinary proceedings that can suspend or revoke that license. Licensing boards treat fraud and dishonesty offenses as grounds for discipline, and a felony conviction often triggers automatic suspension while the board investigates. For attorneys, crimes involving dishonesty or false swearing are treated as “serious crimes” that can lead to disbarment.
For non-citizens, the stakes climb higher. Federal immigration law makes anyone convicted of a crime involving moral turpitude inadmissible, which can mean a denied visa, a blocked green card, or removal proceedings. Fraud and perjury are classic crimes involving moral turpitude. A narrow exception exists for a single offense carrying a maximum possible sentence of one year or less where the person was not sentenced to more than six months, but perjury rarely qualifies because it is almost always a felony.8Office of the Law Revision Counsel.

The Notary Isn’t Taking the Fall for You
It’s a common misconception that the notary vouches for the truth of what the document says. They don’t. Their job is to confirm your identity, confirm you’re signing willingly, and administer the oath when the document requires one.9American Society of Notaries. Your Basic Duties as a Notary Public A notary who did their job properly isn’t on the hook when you lie. The responsibility sits with the signer, which is why every consequence above lands on you.
