Material Non-Disclosure in Financial Remedy Proceedings: What It Is and What You Can Do About It

Divorce financial settlements are built on one foundational principle: both parties must give full and frank disclosure of their financial circumstances. When one side deliberately conceals assets, undervalues a business, or hides income, the entire settlement can be undermined — sometimes years after it was made.

What Counts as Material Non-Disclosure

Every party to financial remedy proceedings owes the court and the other party a duty of full and frank disclosure. This applies whether the case proceeds by court application or is resolved through negotiation and a consent order. Non-disclosure becomes "material" when the withheld information would have made a difference to the outcome — not every omission or inaccuracy will meet this threshold.

Common examples include:

• Undisclosed bank accounts, investments, or cryptocurrency holdings
• Deliberate undervaluation of a business or property
• Concealed income, bonuses, or dividends
• Hidden interests in offshore trusts or entities
• Failure to disclose a new relationship with financial implications (such as cohabitation affecting needs-based claims)
• Dissipating or transferring assets to third parties in the run-up to proceedings

The key Supreme Court authorities — Sharland v Sharland and Gohil v Gohil [2015] UKSC 60/61 — confirmed that fraud is a recognised ground for setting aside a financial order, and that a court will not seek to speculate on what it would have ordered had the truth been known. If the fraud "vitiated" the applicant's consent, the burden shifts to the non-discloser to show the fraud would have made no difference. That is a hard burden to discharge.

What You Can Do About It

During proceedings

If you suspect non-disclosure before an order is made, don't wait for a final hearing to raise it:

• Questionnaires and Form E scrutiny — cross-reference lifestyle against declared income, check for lifestyle inconsistencies, and scrutinise business accounts, director's loan accounts, and related-party transactions.
• Third party disclosure orders — under FPR 21.2, disclosure can be sought from banks, accountants, or business partners.
• Freezing injunctions — where dissipation is a real risk, an application under s37 MCA 1973 or the court's inherent jurisdiction can restrain disposal of assets.
• Adverse inferences — where a party fails to give proper disclosure, the court can draw inferences that the truth is less favourable to them than what has been disclosed (NG v SG [2011] EWHC 3270).
• Judgment summons/committal — in cases of serious non-compliance with disclosure orders.

After an order has been made

This is where it gets harder. An order obtained by fraud or material non-disclosure can be set aside, but the routes differ depending on how the case was decided:

• Consent orders — can be challenged by fresh application to set aside, typically on the basis established in Sharland/Gohil (fraud) or the older Livesey v Jenkins [1985] principle (material non-disclosure short of fraud, where it would have led to a substantially different order).
• Contested/litigated orders — appeal is generally the correct route where the order was made following a fully contested hearing, though set-aside applications remain available in appropriate cases.
• Barder events — a separate and narrower jurisdiction (Barder v Barder [1988]) for a subsequent unforeseen event that invalidates the basis of the order — not the natural route for non-disclosure, but relevant if related timing issues arise.

Applications to set aside must be brought promptly. Delay is a significant factor the court will weigh, and there's a real risk of losing the remedy simply through inaction once the non-disclosure comes to light.

Costs and other consequences

Non-disclosure is treated seriously on costs. Although the general "no order as to costs" starting point applies in financial remedy proceedings, litigation misconduct — including non-disclosure — is expressly carved out as a factor that can justify a costs order against the offending party (FPR 28.3). In serious cases, non-disclosure can also amount to contempt of court, and in extreme cases has been prosecuted as fraud.

The Practical Reality

Set-aside applications on grounds of non-disclosure are resource-intensive, evidentially demanding, and not guaranteed to succeed even where suspicion is well-founded. Courts are alert to satellite litigation and will not reopen settled orders lightly — the finality of litigation is itself a public interest the court protects. Early forensic accounting input, careful pleading of exactly what was withheld and why it's material, and a clear-eyed assessment of proportionality (legal costs against likely uplift in settlement) should shape the strategy from the outset.
