Lying under oath in NSW is a serious offence, but not everyone fully understands what counts as perjury or the punishment for lying under oath under NSW law. Courts rely on honest testimony to deliver fair outcomes, and giving false evidence intentionally can carry severe legal consequences.
This article explains what lying under oath actually means, when a statement becomes perjury, the penalties you could face in NSW, and what to do if you’re accused. It’s a practical guide for anyone concerned about their responsibilities in court or facing allegations of dishonesty under oath.
What Does Lying Under Oath Mean in Legal Terms?
When a person gives evidence in court or provides certain formal statements, they are usually required to swear an oath or make an affirmation. An oath is a promise, often sworn on a religious text, to tell the truth. An affirmation serves the same legal purpose but does not have a religious element. Once a person has sworn or affirmed, they are legally bound to be truthful.
Perjury occurs when a person knowingly makes a false statement after taking an oath or affirmation. This can include spoken testimony given in court, as well as written statements such as affidavits or statutory declarations. Perjury under oath is classified as a serious criminal offence, not merely a procedural issue or ethical breach.
To fully understand how these offences are categorised and prosecuted, it is helpful to have a basic understanding of how criminal law operates in NSW.
Is Lying in Court Always Considered Perjury?
Many people assume that any incorrect statement made in court automatically results in criminal liability. In reality, lying in court is only considered perjury if specific legal requirements are met. The prosecution must show that the statement was false, that it was made under oath or affirmation, and that it related to a matter that was material to the proceedings.
This applies across many areas of law, including criminal cases and family law disputes. For example, providing deliberately false evidence in parenting or property proceedings can still expose a person to perjury charges if the evidence was given under oath and intended to mislead the court.
When Is a False Statement Not Considered Perjury?
There are several situations where a false statement will not be treated as perjury under NSW law. One common example is where a person genuinely believed the statement to be true at the time it was made. Even if later evidence shows that the statement was incorrect, the absence of dishonest intent is critical.
Statements that are irrelevant to the outcome of the case may also fall outside the definition of perjury. Courts recognise that witnesses may be nervous or confused, particularly in complex proceedings before higher courts such as the Supreme Court, and these factors are carefully considered.
The Offence of Perjury Under NSW Law
In New South Wales, perjury is governed by the Crimes Act 1900. The legislation sets out the elements that must be proven before a person can be convicted. Broadly speaking, the prosecution must establish that the accused made a false statement under oath or affirmation, in or in connection with a judicial proceeding, and that they knew the statement was false or did not believe it to be true.
Perjury under oath can arise in criminal trials, civil litigation, and family law proceedings. Because it strikes at the heart of the judicial system, it is treated as a serious criminal offence regardless of the type of case in which it occurs.
The Complex Process of Prosecuting False Statements Under Oath
Even though lying under oath is a serious offence, prosecuting it is not always straightforward. The law sets a high bar to make sure that only deliberate lies are punished and genuine mistakes are not criminalised.
1. Proving Intent Beyond Reasonable Doubt
To secure a perjury conviction, prosecutors must show that the person knowingly lied or didn’t believe their statement was true. This is often the hardest part to prove. Simple inconsistencies in testimony are not enough; prosecutors need supporting evidence such as prior statements, documents, or the individual’s behaviour to show that the false statement was deliberate. This requirement reflects the presumption of innocence, placing the burden of proof squarely on the prosecution.
2. Separating Lies From Honest Mistakes
Courts understand that memory can be unreliable, especially under stress. Confusion, misunderstanding, or emotional pressure which is common in family law or serious criminal trials can lead to genuine mistakes. Prosecutors must prove that the false statement wasn’t just an innocent error.
3. Considering the Impact on the Case
Authorities also look at whether the false statement actually affected the outcome of the trial. If the incorrect statement had little or no influence on the proceedings, pursuing a prosecution may not be necessary.
4. Weighing Public Interest
The decision to prosecute takes into account public interest factors, such as the seriousness of the alleged perjury, the resources required to pursue the case, and whether taking legal action is necessary to maintain trust in the justice system.
Because of these challenges, allegations of perjury are rarely simple. Anyone facing such claims should seek early legal advice to understand whether the elements of the offence are actually made out and to protect their rights.
Punishment for Lying Under Oath in NSW
The punishment for lying under oath in NSW can be severe. Courts view perjury as conduct that undermines public confidence in the legal system. Under NSW law, the maximum penalty is ten years imprisonment, with higher penalties available in particularly serious cases.

Can You Go to Jail for Lying in Court?
Yes, lying in court can result in imprisonment. Custodial sentences are more likely where false evidence leads to wrongful convictions, significant injustice, or prolonged proceedings. Matters heard in higher courts, including the Supreme Court, may attract greater scrutiny due to their seriousness.
Are There Fines for Perjury?
In less serious cases, courts may impose perjury fines instead of, or in addition to, imprisonment. Fines are assessed based on the seriousness of the conduct and the offender’s circumstances. While fines may appear lenient, a conviction still carries lasting consequences.
Can You “Take Back” a Lie Under Oath?
Correcting false evidence does not automatically remove criminal liability. While early and voluntary corrections may be taken into account, the offence may already be complete once the false statement is made under oath.
What Factors Affect the Sentence for Perjury?
Courts consider aggravating factors such as the impact on other parties, interference with justice, and whether the lie was sustained over time. Mitigating factors include early admissions, cooperation, and personal circumstances. The court aims to impose a proportionate sentence that reflects the seriousness of the criminal offence.
Other Consequences of Lying Under Oath
A perjury conviction results in a criminal record, which can affect employment, professional licensing, and credibility in future proceedings. These consequences apply regardless of whether the matter arose from criminal law, civil litigation, or family law disputes.
