One of the most common questions in divorce cases concerns whether bad behaviour during the marriage can influence the financial outcome. Many clients assume that acts such as infidelity, domestic abuse, or other forms of misconduct will automatically affect the division of assets. In reality, the law takes a much more restrained approach. Section 25(2)(g) of the Matrimonial Causes Act 1973 instructs the court to consider “the conduct of each of the parties, if that conduct is such that it would in the opinion of the court be inequitable to disregard it.” While this wording appears broad, judicial interpretation over time has significantly narrowed the circumstances in which conduct is relevant to financial settlements.
Courts have consistently emphasised that the primary aim of financial remedy proceedings is fairness, not punishment. The behaviour of either spouse will only influence financial outcomes when it meets a very high threshold. The law recognises that marriage is complex and that human behaviour often falls short, it does not automatically equate wrongdoing with a financial penalty.
The High Threshold: “Obvious and Gross”
The current framework originates from Wachtel v Wachtel [1973], in which the Court of Appeal held that conduct would only be relevant if it were both “obvious and gross.” This decision established the principle that minor or hidden misconduct has no bearing on financial awards. The House of Lords later reinforced this approach in Miller v Miller [2006], emphasising that courts should not use financial remedy proceedings to punish a spouse for moral failings. Instead, the courts’ role is to achieve a fair division of assets, taking account of circumstances that make ignoring certain conduct inequitable.
Judges have stressed that this threshold is deliberately high to prevent financial disputes from devolving into moral battles. By limiting consideration to conduct that is obvious and severe, the courts maintain a focus on fairness and financial justice rather than retribution.
The Emergence of a Financial Consequence Requirement
In recent years, courts have clarified that conduct must generally have a financial impact to influence the outcome of a financial remedy. In OG v AG [2020], Judge Mostyn highlighted that the financial remedy court is “no longer a court of morals” and cautioned against penalising immoral behaviour in the absence of financial effect. He suggested that conduct should only be reflected in financial awards when its consequences can be measured or quantified in financial terms.
This approach was further developed in Tsvetkov v Khayrova [2023], where Judge Peel categorised relevant conduct into four distinct types, each with its own considerations:
1. Gross Personal Misconduct
For conduct to be taken into account, it must be so serious that the court would consider it inequitable to disregard. Peel J emphasised that cases involving gross personal misconduct are exceptional. They are unlikely to affect the financial outcome unless there is a clear financial consequence flowing from the behaviour. In N v J [2024], Peel J stated that a financial consequence is “invariably a necessary ingredient” of a conduct claim, even if it cannot always be measured precisely.
Domestic abuse, while morally unacceptable, does not automatically justify a financial adjustment. Courts only consider conduct where it leads to tangible financial consequences, such as reduced earning capacity, increased living needs, or the need for ongoing care. For instance, in Jones v Jones [1975], the husband assaulted his wife, inflicting injuries that caused permanent disability. She became virtually unemployable and could not continue her career as a nurse. The Court ruled that the husband’s conduct was so serious and financially damaging to his wife that it could not be ignored. This case highlights that conduct alone is insufficient; the financial impact must be evident.
2. Add-Back for Dissipated Assets
Courts may also address situations in which one spouse has recklessly or wantonly depleted marital assets. This is known as an add-back claim. While the Court cannot restore money that has already been spent, it can adjust the distribution of the remaining assets to reflect the dissipation.
In Martin v Martin 1977, the Court made it clear that a spouse cannot recklessly deplete assets and then claim an equal share of what remains. Even in cases of extreme spending, the threshold for add-back is high. In MAP v MFP [2015], the husband spent large sums on drugs and prostitution, yet the Court declined to add these sums back. Mr Justice Moor observed: “A spouse must take his or her partner as he or she finds them. Many very successful people are flawed.” These cases illustrate that add-back claims are highly fact-specific and relatively rare, requiring clear evidence that the depletion was deliberate and materially affected the marital assets.
3. Litigation Misconduct
Financial proceedings require parties to comply with court directions and procedural timelines. Litigation misconduct includes failing to attend hearings, breaching court orders, or refusing to participate constructively in settlement discussions after full disclosure has been provided. In such cases, the Court may order the offending party to pay or contribute to the other party’s legal costs.
For example, in Helliwell v Entwistle [2024], the court ordered the husband to pay £75,000 towards his wife’s legal costs. He had exaggerated his claims and pursued litigation challenging a prenuptial agreement that he had freely signed after receiving independent legal advice. Litigation misconduct allows the Court to enforce compliance and fairness without turning financial remedy proceedings into punitive moral judgments.
4. Non-Disclosure
Parties have a duty to provide full and frank disclosure of their financial circumstances. Where a party fails to do so, the Court may draw adverse inferences about the existence and value of undisclosed assets. The Court can reflect this by attributing an assumed value to such assets when determining the overall division. Non-disclosure ensures transparency and prevents parties from benefiting from foul play.
Final Thoughts
Financial remedy proceedings are designed to achieve fairness, not to punish spouses. The introduction of no-fault divorce further reduces the relevance of assigning blame. Expanding the scope of conduct risks higher costs, delays, and increased hostility. Over-scrutinising personal misconduct could turn financial remedy cases into fault-based disputes, creating evidential challenges and destabilising settlements.
The courts consistently emphasise that fairness should guide decisions, not moral judgment. Conduct claims are complex and expensive, with strict evidential requirements. Early specialist legal advice is therefore essential. Lawyers can help parties realistically evaluate the prospects of a conduct-based claim, explore alternative strategies, and achieve a fair and sustainable financial outcome.
Ultimately, the overarching message from the courts is clear: focus on fairness, consider financial consequences, and avoid moral judgment. By following this principle, the court ensures that financial remedies support independence, rather than serving as a vehicle for punishment.
