At Martyn Prowel Gartsides, our specialist high net worth divorce solicitors in Cardiff act for individuals and families whose financial affairs go beyond a straightforward split of assets — business interests, property portfolios, farms, pensions and investments that need careful, discreet handling. We are a leading family law firm in South Wales, recommended in the Legal 500 and LEXCEL accredited, with over 65 years of combined heritage behind our advice.
We understand that a high net worth divorce carries a different set of pressures to a standard case. There is more at stake, more to disclose, and often more people — children, business partners, wider family — affected by the outcome. Our Cardiff team is experienced in managing exactly this kind of complexity, and works closely with accountants, financial advisers and valuers where a case requires it, so that every asset is properly identified and fairly accounted for.

What Counts as a High Net Worth Divorce?
There is no fixed legal threshold that defines a high net worth divorce. In practice, the term is used where a couple’s combined assets are substantial or complex enough to require specialist valuation and disclosure — this might include a family business, multiple properties, significant pension provision, investment portfolios, or inherited wealth. What matters most is not the total figure but the complexity of untangling it fairly, which is why cases like these benefit from a solicitor experienced in this specific area of family law.
Business Assets in a Divorce
Where one or both parties own a business, that business will usually need to be valued and considered as part of the financial settlement — whether it is a sole trading concern, a partnership, or a limited company. This does not automatically mean the business has to be sold. Depending on the circumstances, a business can often be retained by the party who runs it, with the other party’s interest offset through other assets, a lump sum, or a structured payment arrangement.
Our solicitors work with forensic accountants and business valuers to ensure a business is properly valued and that any settlement reflects both its value and its ability to continue trading. We understand how much is riding on this for business owners, and we approach these cases with the commercial awareness they require.
Farms and Rural Estates
For farming families across Monmouthshire, Blaenau Gwent and the wider Abergavenny and Ebbw Vale area, divorce raises questions that go well beyond a standard financial settlement — land that has often been in a family for generations, agricultural property relief, tenancies, and the practical question of whether a farm can remain viable if assets are divided. Our Abergavenny team, led by Sian Lewis, has particular experience supporting farming families through this process, balancing fairness to both parties with the long-term future of the farm itself.
Pensions in a High Net Worth Divorce
Pensions are often one of the most significant — and most overlooked — assets in a divorce, and in many cases are worth as much as the family home. Our solicitors advise on pension sharing orders, pension attachment orders, and pension offsetting, working with independent financial advisers where a pension valuation needs specialist input.
Protecting What You’ve Built — Prenuptial and Postnuptial Agreements
For clients entering a marriage with significant assets, or wishing to formalise arrangements during one, a prenuptial or postnuptial agreement can provide clarity and protection should the relationship later break down. While not automatically binding in the same way as a contract, agreements that are properly drafted, with independent legal advice for both parties and full financial disclosure, are given significant weight by the courts.
Reaching a Financial Settlement
Once assets have been identified and valued, our solicitors work to reach a financial settlement that is fair, sustainable, and — wherever possible — agreed without the need for lengthy court proceedings. This may take the form of a clean break order, drawing a firm line under future financial claims, or a consent order recording an agreed settlement for approval by the court.
Spousal Maintenance
Where there is a significant difference in income between spouses, spousal maintenance may form part of a settlement. Our solicitors advise on whether maintenance is likely to apply, how it might be calculated, and how it interacts with other elements of a settlement such as capital and pension division.
Hidden and Non-Matrimonial Assets
Full and honest financial disclosure is a legal requirement in divorce proceedings, but in high value cases it is not unusual for one party to suspect the other of understating their assets. Our solicitors are experienced in identifying gaps in disclosure and, where necessary, taking steps to establish the true financial picture. We also advise on non-matrimonial assets — such as inheritances or assets acquired before the marriage — and the circumstances in which these may or may not be included in a settlement.
