Ultra-high-net-worth divorce operates in a different universe from standard family law. When the marital estate runs into tens or hundreds of millions – sometimes billions – the legal proceedings resemble hostile corporate transactions more than they do conventional divorce cases. Assets are held in layered trust structures, spread across jurisdictions, and deliberately obscured behind corporate vehicles. Valuations are contested by teams of forensic accountants. And the legal costs alone can run into seven figures.
Finding the right firm for a UHNW divorce isn’t about finding a “good family lawyer.” It’s about finding a practice that understands how serious wealth is structured, how to attack or defend complex asset arrangements, and how to conduct litigation at a level of sophistication that matches the sums at stake.

What to Look For in a UHNW Divorce Solicitor
- Track record at scale. There is a meaningful difference between handling a £2 million divorce and a £200 million one. The legal principles may be similar, but the strategic complexity, the expert evidence required, and the litigation tactics involved are entirely different. Ask about case values, not just case numbers.
- Trust and structure expertise. UHNW cases almost always involve trusts, corporate structures, or offshore arrangements. Your solicitor needs to understand these – not as abstract concepts, but as practical instruments that can be challenged, unwound, or defended in court.
- Access to top counsel. The most complex UHNW cases require leading barristers (KCs) who specialise in financial remedy. Your solicitor should have established working relationships with the best family law KCs and know which counsel is right for your specific case.
- Discretion and privacy. UHNW clients are often public figures or prominent business people. Your solicitor should understand how to manage press interest, apply for reporting restrictions, and keep sensitive financial information out of the public domain.
Frequently Asked Questions
What qualifies as “ultra-high-net-worth” in divorce terms?
There is no strict legal definition, but in practice UHNW divorce cases typically involve combined marital assets of £10 million or more. Chambers & Partners distinguishes between HNW and UHNW practices, with the latter handling cases at the very top end of financial complexity and value.
How do courts deal with trust assets in UHNW cases?
English courts can consider trust assets as a financial resource available to a party, even if the trust is technically discretionary. The court may invite trustees to make funds available, and in some cases may “pierce the corporate veil” if the trust is found to be a device to defeat a spouse’s financial claims.
Can I protect my business from divorce?
You cannot make a business entirely divorce-proof, but measures like prenuptial agreements, shareholder agreements, and careful structuring can influence how the court treats business assets. The court will always consider the needs of both parties, but well-drafted agreements can provide significant protection.
How much does a UHNW divorce cost?
Legal costs in UHNW cases can range from £100,000 to over £1 million per party, depending on the complexity and whether the case reaches a final hearing. The most hotly contested cases – involving multiple experts, contested valuations, and extended hearings – can cost several million pounds in total.
Should I use a boutique or a full-service firm?
Both models can work well for UHNW cases. Boutiques like Katz Partners and Hughes Fowler Carruthers offer exclusive senior partner focus. Full-service firms like Withers and Vardags provide integrated tax, trust, and commercial advice alongside family law. The choice depends on whether your case requires pure family law expertise or broader multi-disciplinary coordination.
