The legal framework: Why honesty matters
The legal system treats honesty in court proceedings as a fundamental pillar of justice. When individuals deliberately lie under oath or mislead the court, they may be committing perjury in family court UK. Family law judges rely on factual, transparent information to make decisions in the best interest of children and fair outcomes for all parties.
Although family courts are considered civil, and not criminal, lying under oath can still be prosecuted as a criminal offence. The court may also impose sanctions such as fines, adverse cost orders, or even imprisonment in extreme cases. In short, the consequences of lying in family court UK can be far-reaching and affect both the outcome of your case and your credibility in any future legal matters.
Scenario 1: A parent lies about domestic abuse
Imagine a mother alleges that her ex-partner has been violent in front of their child. The court, concerned for the child’s welfare, may restrict the father’s contact. But if it later emerges that the allegations were fabricated, the mother could face severe repercussions, including:
-
Losing custody of the child
-
Facing prosecution for perjury in family court UK
-
Being ordered to pay the other party’s legal costs
This scenario demonstrates how vital it is that all claims made in court are supported by credible evidence. False allegations not only waste court resources but also deeply affect the lives of the accused and any children involved.
Scenario 2: Financial dishonesty in divorce proceedings
In another case, a husband under reports his income to avoid having to make higher spousal maintenance payments. However, bank statements and employer disclosures later reveal the discrepancy. The court may then:
-
Reopen the financial settlement
-
Impose a higher payment structure
-
Refer the matter for prosecution for perjury in family court UK
Attempting to hide assets or income is a common but serious form of dishonesty that family courts are well-equipped to detect.
Can one person’s word against the other count as lying?
The court relies on individuals to tell the truth in order that a fair decision can be reached. It is extremely common in family law cases for disputes to come down to one person’s word against the other. One parent’s version of events is often drastically different from the other parent’s, and in cases of domestic abuse, which tends to happen behind closed doors, it is rare for there to be any witnesses to corroborate the victim’s story. In finance disputes, one party may be in the dark about the extent of the other’s wealth, which makes it easier for them to provide misleading information within their Form E. So it really does all hinge predominately on the facts of the case.
In 2022, a husband was sent to a term of imprisonment of seven and a half months after he dishonestly edited emails from estate agents that lowered the value of the family home during divorce negotiations. Although this case was decided on the Isle of Man, which has a separate legal system, it demonstrates what could happen if someone deliberately misled the court.
Is lying in a family case considered to be perjury?
The offence of perjury is contained in the Perjury Act 1911, and occurs when someone who has lawfully sworn as a witness in judicial proceedings wilfully makes a statement they know to be false or do not believe it to be true. Perjury is an extremely serious offence with punishments including fines, community service, and up to seven years in prison. But can lying in a family case amount to perjury?
Lying in a family proceedings can constitute perjury, although it is complicated, with a two part test needing to be satisfied. For an individual to be convicted of perjury, they have to know that what they are saying is a lie. This is often not the case in family disputes where emotions run high with parties genuinely believing that a statement is true, even if no one else interprets what has happened in the same way. The second part of perjury is that the lie must be made whilst the person is under oath. Anyone providing false evidence during a court hearing will meet this requirement. This also includes written statements sworn to be true, such as an affidavit.
Vast swathes of information given during family proceedings are not submitted under oath. False information given in a witness statement or a Form E, for example, would probably not count as perjury, but could amount to a lesser offence, such as making a false declaration of truth on a questionnaire.
Judges are getting more creative in how they deal with dishonesty in court proceedings. In the recent case of Baker v Baker, the wife applied for maintenance pending suit with both parties being required to give full and frank financial disclosure. The judge described the husband’s disclosures as “lamentable” with “incorrect representations being followed hard on the heels by false statements”. The court ordered the husband to provide replies to the wife’s questionnaire as a sworn statement – an oath. This meant that lying on the document could lead to charges of perjury attracting a maximum prison sentence of seven years. In contrast, making a false declaration of truth on a questionnaire carries a maximum prison sentence of two years for contempt of court. Interfering with the administration of justice may take several forms, but each of them will result in justice itself not being properly carried out. It is for this reason that contempt of court is seen as such a serious offence which can, as stated, merit a custodial sentence being handed down.

What are the punishments for lying in court?
It is incredibly risky to lie to the court because doing so can have far reaching consequences. These are:
- The judge may draw adverse inferences from your behaviour, which may influence their decision. In children proceedings, for example, you could end up with less time with your children than you otherwise would have if you had been truthful.
- If a judge believes you are hiding assets, they have the power to award your ex a greater share of the property the judge knows is there, taking a broad brush approach about what other assets you may be concealing.
- You may receive a costs order against you, especially if the case has taken longer and additional expenses have been incurred as a result
- You may be held in contempt of court. Although this is not a criminal offence, it can lead to fines, community orders, or up to two years in prison
- There is the possibility of prosecution for perjury which, as we have seen, attracts a maximum 7 year term of imprisonment. Following the Baker case (discussed above), it may lead to more judges using the full force of perjury laws to crack down on lies.
Lies will always be caught out. Arguably, it is better to be honest about something you may be ashamed of, than be found to have spun a web of lies. As we have seen, lying to the court can have disastrous consequences for both your case and your future. If you have a solicitor, they will guide you in how best to present your version of events to the court with honesty and integrity.
How to stop yourself from providing false information (unintentionally)
It is possible to mislead the court without meaning to, especially when recalling events from memory. Here’s how to avoid that:
- Keep detailed records: Whether it is a conversation with your ex, childcare arrangements, or financial transactions, keeping detailed notes and evidence can help you remain accurate.
- Speak with a solicitor: Your legal representative can help ensure your statements are clear and supported by documentation. Always run important submissions by them before sending anything to the court.
- Read everything twice: When preparing statements, re-read them carefully and cross-reference with your evidence. This helps reduce the risk of accidental inconsistencies.
Remember, the court distinguishes between genuine mistakes and deliberate lies—but being careful from the start protects your credibility.
Preventing an ex from providing false information
If you suspect your ex is bending the truth or outright lying, you’re not powerless. Here’s how to address it:
- Collect evidence: The best response to dishonesty is evidence. Text messages, emails, social media posts, and witness statements can all help contradict false claims. This is central to how to prove someone is lying in court.
- Use cross-examination wisely: During hearings, your solicitor or barrister can use cross-examination to expose contradictions in your ex’s statements.
- Request a fact-finding hearing: If serious allegations (e.g., abuse or neglect) are being made, you can ask the court to hold a fact-finding hearing. This allows the judge to determine which allegations can be substantiated.
Being proactive and prepared is key. Knowing how to prove someone is lying in court can significantly impact the final outcome.

How to prove someone is lying in court
Knowing how to prove someone is lying in court is essential, particularly when the lie could sway the judge’s decision. Some tips include:
-
Compare statements: Look for inconsistencies over time in your ex’s claims.
-
Seek third-party verification: Involving teachers, doctors, or professionals can help verify your version of events.
-
Submit tangible evidence: Documents, financial records, and correspondence can be more reliable than memory or hearsay.
Successfully challenging a lie not only protects your position in court but may also result in your ex facing legal consequences, especially if their statements amount to perjury in family court UK.
