Financial Planning Through and After Divorce: What’s Specifically Different at the Higher Net Worth
A founder valued personally at £4m sitting on a £15m business interest, going through divorce in 2026, faces planning decisions that simply don’t exist for the £400,000 average UK divorce settlement. Pension sharing on £2m+ pensions. Business valuation in matrimonial proceedings. The interaction between exit timing and the financial settlement. The CGT consequences of asset transfers. And the recent shift in case law on what counts as matrimonial property in the first place. The technical scaffolding underneath HNW divorce is materially different and most generic financial planning advice doesn’t engage with it.
Divorce is one of the most consequential financial events most clients will experience. For HNW clients such as business owners, senior executives, families with multi-asset balance sheets, it is also one of the most technically complex. The interaction between the legal proceedings and the financial planning sits across multiple disciplines, and the decisions made in the twelve months around the settlement compound for the rest of the client’s life.
This article is a practical guide to what’s specifically different about HNW divorce planning. It assumes the legal proceedings sit with a specialist family law solicitor, the financial planning context is what we cover here.
Pension sharing at the higher net worth level
For most UK divorces, the pension is the second-largest asset after the family home. For HNW clients, it can be the largest single asset on the balance sheet, £2m+ of pension capital is not unusual for senior executives or successful business owners with long employer-contribution histories.
Three structural points worth understanding.
Pension Sharing Orders are the dominant approach. Under a Pension Sharing Order, a defined percentage of the pension’s cash equivalent value (CEV) is transferred from one spouse’s pension to a pension in the other spouse’s name. The transfer happens cleanly at the point of divorce and produces two genuinely separate retirement assets thereafter. For most HNW divorces this is the right structural answer because it produces independence, certainty, and the ability for each party to plan their own retirement strategy.
Pension offsetting is alluring and often a worse outcome. The alternative, keeping the pension intact in exchange for giving up other matrimonial assets of equivalent value looks simple but rarely produces equivalent long-term wealth. £1m of pension capital and £1m of GIA (general investment account) are not the same asset. The pension grows tax-free, the GIA pays CGT and dividend tax annually. The pension has a 25% tax-free lump sum on drawing, the GIA does not. The pension was, until April 2027, IHT-free on death, the GIA is in the estate. Even after the April 2027 IHT changes, the pension’s tax-free growth advantage compounds over decades. Offsetting almost always favours the spouse keeping the pension over a long horizon.
Pension earmarking is usually a structural mistake. The third option, receiving income payments from the ex-spouse’s pension when they begin drawing it, keeps the recipient dependent on the timing and behaviour of the ex-spouse, ties the parties together for decades, and produces no separate pension wealth in the recipient’s own name. For HNW clients, earmarking is rarely the right answer.
The technical point underneath all three is that the pension’s CEV is the headline number, but the actual long-term value depends heavily on what type of pension it is, what fund it is invested in, what the death benefit rules look like, and how it interacts with the post-April 2027 IHT regime. Two pensions with identical CEVs can produce materially different outcomes for the recipient depending on these factors.
Business interests in matrimonial proceedings
For business owner clients, the business is usually the most complex asset in the proceedings. Three structural questions tend to drive the planning.
Valuation methodology matters more than valuation accuracy. A business can be valued on a multiple of recent earnings, on a discounted cashflow basis, on a fair market basis with comparable transactions, or on an assets basis. Each produces a different number, sometimes by 30% or more. The methodology selected by the court-appointed expert (or the methodology the parties’ experts agree on) materially affects the financial settlement. For business owners, engaging with the valuation methodology early, alongside the family lawyer, is one of the higher-impact planning steps available.
The timing of business sales relative to proceedings is structurally important. A planned exit eighteen months after divorce produces a different financial settlement from a planned exit eighteen months before. Where an exit is genuinely on the horizon, the timing decision interacts with both the sharing principle (post-marital exit value may be treated differently from pre-divorce exit value) and the tax planning (BADR holding period, CGT timing, reinvestment relief). This is one of the conversations where the family lawyer, the corporate finance adviser, and the financial planner all need to be in the same room.
Liquidity in the settlement is a real planning issue. A founder whose £15m business interest produces a £6m financial settlement in favour of the other spouse needs the £6m to come from somewhere. If the business is illiquid, the practical answer involves either staged payments over time, security against the business, refinancing, or partial sale to release capital. Each has tax and structural consequences. Generic divorce planning advice typically doesn’t engage with this, for HNW clients it is often the central financial planning question.
Capital gains tax
The transfer of assets between spouses in connection with divorce is subject to specific CGT rules. Transfers between spouses generally fall under the no gain, no loss principle, meaning the transferring spouse passes their original base cost to the receiving spouse rather than triggering a CGT event.
The structural implication is that the order of asset transfers matters. A spouse who receives a £1m portfolio of equities with a £200k base cost needs to plan for the eventual CGT liability when those equities are sold, even though no CGT has been paid at the point of transfer. The planning conversation should explicitly include base cost analysis on transferred assets, not just headline values.
The post-divorce planning agenda
Once the financial order is in place and the transfers have been completed, the post-divorce planning agenda is genuinely substantial. For most HNW clients, the post-divorce balance sheet is materially different from the pre-divorce one, usually with more wrappers in personal name, a different pension structure, a different income tax position, and often new dependants to plan around.
Five structural items typically need attention in the first six to twelve months:
The pension architecture. A £2m pension received via Pension Sharing Order needs to be reviewed against the post-April 2027 IHT regime, against the recipient’s own retirement timeline, and against any continuing employer pension contributions in their own name. The drawdown sequencing question (pension vs ISA vs GIA) is now genuinely a personal planning question rather than a household one, and the answer often differs from the pre-divorce strategy.
Tax wrapper rebuild. ISAs are individual, the new financial reality may involve maxing out ISA allowances afresh from the post-divorce position. CGT and dividend allowances now apply at the individual level rather than across the household. The full architecture across pension, ISA, GIA, and bond benefits from being looked at fresh rather than continued from the pre-divorce structure.
Cashflow modelling on the new basis. A 30-year cashflow model run on the post-divorce balance sheet, with the new income, the new outgoings, and the post-2027 IHT regime, is usually meaningfully different from the pre-divorce model. The exercise is worth doing in the first six months rather than the first three years.
Will, power of attorney, and beneficiary designations. Often forgotten in the immediate post-divorce period and almost always urgent. Pension nominations, life policy beneficiaries, ISA and investment account designations, and the will itself need to be reviewed and updated. A pension that still names an ex-spouse as the beneficiary on death is not merely an administrative oversight, it can override the financial settlement entirely if the policyholder dies before the nomination is updated.
Estate and succession planning on the new structure. For HNW clients, the post-divorce estate planning conversation is often genuinely different from the pre-divorce one. Children’s inheritance arrangements, lifetime gifting strategy, IHT exposure, and any trust structures need to be reconsidered against the new shape of the family balance sheet.
What this means in practice
If you are reading this because you are going through, or have recently completed, a divorce involving meaningful wealth, three structural questions are worth working through:
Is the pension architecture in the settlement actually optimal for both parties, or just numerically equal? Pension sharing produces independence and certainty, offsetting is often structurally worse for the receiving spouse over a long horizon. The decision is worth modelling explicitly rather than defaulting to whichever structure feels simpler in the negotiation.
Have base costs and tax timing been built into the asset transfer plan? A £1m portfolio with a £200k base cost is not the same asset as £1m of cash.
Has the post-divorce balance sheet been modelled against the post-April 2027 IHT regime? For any client with significant pension wealth in the settlement, the strategy designed before the regime change almost certainly needs rebuilding. The post-divorce period is the right window to do it, while the architecture is being reset anyway.
The financial planning conversation through and after divorce is genuinely cross-disciplinary. It works best alongside specialist family law counsel, often a tax adviser, and where business interests are in scope, corporate finance support. The role of the financial planner is to hold the long-term picture together across the disciplines and ensure the decisions taken in the heat of proceedings still make sense five and ten years later.
