Lambert v Lambert: When does business success justify an unequal divorce settlement?
By Aleksandar Cvetkov
The Court of Appeal’s decision in Lambert v Lambert [2002] EWCA Civ 1685 considered whether one spouse’s exceptional financial success should entitle them to a greater share of the family’s wealth following divorce.

Background to the case
Shan and Harry Lambert were married for 23 years and had two children. During the marriage, Mr Lambert developed Adscene Ltd, a free local newspaper business which had been established shortly before the couple married.
The business grew considerably throughout the marriage and was eventually sold as part of a £75 million takeover. By the time of the divorce proceedings, the assets available to Mr and Mrs Lambert were valued at approximately £20.2 million.
Mr Lambert argued that his business skills, determination and hard work had been responsible for creating the family’s wealth. He claimed that this amounted to a “special contribution” and that he should therefore receive a greater proportion of the assets.
Mrs Lambert maintained that the wealth had been created through the marriage as a whole. While her husband concentrated on developing the business, she cared for the home and children and also provided support to the company when required.
The original decision
The High Court accepted that Mrs Lambert had made a full contribution to the marriage. However, it concluded that Mr Lambert’s role in building the business was sufficiently exceptional to justify an unequal division.
Mrs Lambert was awarded approximately 37% of the assets, worth around £7.5 million, while Mr Lambert retained approximately 63%.
She appealed against that decision.
What did the Court of Appeal decide?
The Court of Appeal allowed Mrs Lambert’s appeal and increased her award to 50% of the family assets.
The Court recognised that a genuinely exceptional contribution could, in rare circumstances, justify moving away from an equal division. However, financial success alone was not enough.
Mr Lambert had undoubtedly been a highly successful entrepreneur. Nevertheless, qualities such as hard work, commercial judgment, initiative and determination did not automatically make his contribution more valuable than his wife’s contribution to the home and family.
The Court was particularly concerned that placing greater value on the person who earned the money could result in unfairness. A spouse who assumes responsibility for the home and children will rarely have the same opportunity to demonstrate their contribution through financial figures. That does not make their contribution less important.
The Court also considered the length of the marriage, Mrs Lambert’s age and her future financial position. The marriage had covered many of her most economically productive years, during which she had prioritised the family. Her longer life expectancy and reduced ability to generate further wealth also supported an equal division.
Why is the decision important?
Lambert v Lambert confirms that marriage should be treated as a partnership. Financial and domestic contributions may take very different forms, but the court should not assume that one is more valuable simply because it can be measured in money.
The case does not establish that assets must always be divided equally. The court must still consider all the circumstances, including the parties’ needs, the length of the marriage, the source of the assets and their future resources.
However, where wealth has been generated during a long marriage and both spouses have contributed fully in their respective roles, it will require truly exceptional circumstances to justify awarding the principal income earner a greater share.
