Case study: What assets should I fight for in my divorce as a US expat in the UK?

Key Takeaways

Value Liquidity Over Sentiment: For an expat staying in the UK, fighting for the right assets is more important than simply fighting for 50%.

Beware the Double Tax Trap: US citizens are taxed on worldwide income regardless of where they live. An asset that looks tax efficient in the UK can be a reporting nightmare and a tax burden in the US.

Distinguish Between Marital and Non-Marital Property: In the UK, assets brought into the marriage may be treated differently than those built during it.

What’s your background?

Elena, 52, is a senior director at a global pharmaceutical firm. A US citizen, she moved to London twenty years ago after marrying David, a UK tech entrepreneur. They have two children currently attending UK universities, and Elena has decided to make the UK her permanent home post-divorce to remain close to them and her established career.

David owns a successful software business he founded three years before the wedding. Over two decades, the couple built a significant global estate, a primary residence in London, a vacation home in Florida, and a substantial investment portfolio.

The portfolio is a mix of UK-based ISAs and SIPPs, and US-based 401(k)s and brokerage accounts. Because David handled the money, Elena focused on her career and the children, assuming that a 50-50 split would naturally provide for her future. She is now realizing that the IRS is not overly concerned about UK divorce decrees.

What’s the problem?

The core of Elena’s problem is cross-border inconsistency. While UK courts generally aim for an equitable distribution, they rarely account for the specific tax obligations of a US taxpayer.

David’s software business is a major point of contention. Because he started it before the marriage, he views it as his, yet its growth occurred entirely during their partnership. Meanwhile, the real estate presents a logistical headache. The Florida home is subject to US capital gains rules, while the London home is their primary residence.

The biggest invisible threat lies in the investment accounts. Elena has discovered that their UK investments include Passive Foreign Investment Companies (PFICs), common UK unit trusts or ETFs that the IRS taxes at punishing rates. If she wins these in the divorce, she may inherit a massive tax bill that David, as a UK national, would never have to pay.

Furthermore, Elena needs to ensure her settlement provides enough GBP to live in the UK, while her US-linked retirement accounts are pegged to the USD, creating a currency risk.

What’s the solution?

Elena needs a Financial & Legal Strategy from professionals that understand and are qualified to work in both jurisdictions. She cannot rely on standard UK advice alone.

She needs a forensic valuation of the business. Elena could argue that the growth in value of David’s software company during their 20-year marriage is a marital asset. Even if she doesn't want a share of the company, its value could be used to offset her receiving a larger share of the liquid assets or the London property.

Instead of a 50/50 split of every account, Elena should cherry-pick assets based on her US tax status. She needs to consider the implications of retaining the London home, US brokerage accounts and the various SIPPS, ISAs and 401(k)s.

Her adviser must model her future in Sterling. Fighting for the Florida house might feel like a win, but the costs of maintenance in USD while living in GBP might make it a trophy asset she can't afford to keep.

How will it improve things for you?

By fighting for the right assets rather than just half the assets, Elena secures financial efficiency. She avoids inheriting ‘tax bombs’ that would have silently eroded her wealth year after year. Physically and emotionally, securing the London home provides the stability she needs for her children’s university years. She avoids the stress of managing a US property from abroad or dealing with the complex withholding taxes involved when a non-resident sells US real estate.

Financially, she gains tax compliance peace of mind. Her portfolio will be streamlined for a US expat, meaning her annual accountancy fees will drop and her net-of-tax returns will be higher. She moves forward not just with money, but with spendable money that is protected from both the HMRC and the IRS.
