For many American lawyers and international law firm partners, London remains the global city of choice. It offers prestige, proximity to clients, and an unrivalled lifestyle that complements a career in global legal practice.

Whether it’s a pied-à-terre in Mayfair, a family home in Hampstead, or an investment property in the Square Mile, the demand for UK property among international legal professionals shows no signs of slowing.

But one area continues to trip up even the most successful individuals: arranging finance. Securing a UK mortgage as an American lawyer or international partner is not straightforward. Despite impressive earnings, top-tier law firm credentials, and global reputations, these clients frequently encounter barriers when dealing with UK lenders. The root of the problem lies not in financial strength, but in the complex way income is earned, reported, and paid across multiple currencies and jurisdictions.

The Global Nature of Legal Income

American lawyers and international law firm partners often earn income in a patchwork of structures: base salaries in dollars, profit shares in sterling, overseas retainers in euros, and bonuses tied to deals denominated in local currencies. Add to this the fact that many large international law firms operate through profit distribution systems — where income is drawn quarterly or even irregularly — and the picture becomes more complex still.

To a mainstream UK high street bank, this kind of income profile does not fit neatly into their underwriting models. Traditional lenders are geared towards applicants who are either salaried employees with payslips or self-employed individuals with UK tax returns covering at least two years. A US lawyer receiving quarterly profit draws, part paid in USD and part in GBP, does not align with either category.

This often leads to misunderstandings, underestimation of borrowing capacity, and even outright rejection from lenders that fail to account for international earnings properly.

Currency Conversion: A Moving Target

One of the most significant pitfalls international lawyers face is the treatment of foreign currency income. UK lenders are inherently conservative when it comes to exchange rate risk. Even when income is stable, the fact that it is earned in USD, EUR, or another currency means lenders will often apply a currency haircut — discounting the income by 20–25% to protect against fluctuations.

For a partner earning $500,000 annually in New York with aspirations of buying a £2 million townhouse in London, this approach can dramatically reduce assessed affordability. The situation is even more complicated if income is split across multiple currencies, with each subject to its own conversion and risk discount.

This is not just a technicality. It has real consequences: clients who could easily afford repayments on a UK mortgage are denied the level of borrowing they require, simply because of rigid currency policies.

Partnership Structures and Profit Shares

Another key challenge comes from the partnership structures within which many lawyers operate. Law firm partners are often considered “self-employed” in the UK mortgage market, regardless of whether they see themselves that way. Most lenders require at least two years of partnership drawings or tax returns before they will lend — a significant hurdle for newly appointed partners or those who have recently transferred from an overseas office into a UK role.

Some lenders, however, are more sophisticated. They will consider a reference salary — effectively a projected or notional income agreed between the firm and the partner — as the basis for affordability. This mirrors the approach Willow Private Finance has successfully secured for other professionals in transition, such as newly qualified UK partners in tax advisory practices. But these lenders are niche, and access requires knowledge of where to place the application and how to present the case.

Tax Complexities and Cross-Border Considerations

Tax is another area where international lawyers run into mortgage difficulties. US citizens remain subject to US taxation regardless of residency, which means that an American lawyer in London may face overlapping reporting obligations to both HMRC and the IRS. On top of this, they may have tax equalisation agreements with their firm or be operating through complex corporate structures to manage global earnings.

For lenders, this can create confusion and delays. If income evidence spans multiple jurisdictions, multiple currencies, and multiple tax systems, underwriters will often err on the side of caution. The result: reduced borrowing capacity or additional demands for documentation that stretch the application process.

Pitfalls to Avoid

The most common pitfalls international lawyers face when arranging a UK mortgage include:

• Approaching the wrong lenders first. High street banks may quickly decline complex income cases, leaving a mark on credit records and wasting time.

• Underestimating the impact of currency haircuts. Borrowing capacity may fall short of expectations if foreign income is not properly structured.

• Failing to evidence income clearly. Without careful presentation of partnership agreements, reference salaries, and tax documentation, lenders may refuse to proceed.

• Overlooking tax implications. Global lawyers often underestimate the knock-on effect of US tax obligations, particularly where income is pooled from multiple jurisdictions.

• Assuming prestige equals simplicity. Even top international firms do not guarantee a smooth mortgage journey — in fact, their structures often complicate matters.

How Willow Can Help

At Willow Private Finance, we specialise in helping professionals with complex, cross-border income secure the UK property finance they need. We have worked extensively with law firm and tax advisory partners, including American lawyers transferring to London or European partners looking to invest in UK property.

Our value lies in knowing which lenders can accommodate these complexities — from those willing to use reference salaries for newly appointed partners, to others able to credit income in multiple currencies without excessive discounts. We present cases to underwriters in a way that reflects the reality of a client’s financial strength, not just the rigid categories of standard lending criteria.

We also understand the subtleties of cross-border taxation and can work alongside tax advisors to ensure income is evidenced in the most favourable way. For American lawyers in particular, this often means structuring the application to account for IRS obligations while still maximising borrowing capacity under UK rules.

For international professionals, the goal is simple: to secure the right property in the UK without being penalised for the very global structures that underpin their success. At Willow, that is exactly what we help clients achieve.
