Reviewing Cross-Border Assets in 2026 

Overseas Assets, Non-Dom Reforms, and Estate Risk 

2026 is going to be a critical year for solicitors, private client practitioners, and personal representatives to reassess estates with cross-border elements. Recent and forthcoming reforms affecting non-domiciled individuals, combined with increased international transparency and enforcement, mean that overseas assets can no longer be treated as peripheral to estate planning or administration. 

Where estates include property, investments, bank accounts, or business interests held outside the UK or Ireland, a proactive review is now essential to ensure compliance, avoid delay, and protect against unintended tax and distribution consequences. 

The Changing Landscape for Overseas Assets 

Cross-border estates have always carried additional complexity, but regulatory and fiscal developments are accelerating that risk. Reforms to non-domicile status, changes to remittance and residency rules, and ongoing international data-sharing agreements are reshaping how overseas assets are viewed by tax authorities and the courts. 

Assets that may previously have sat outside the immediate scope of probate or inheritance tax considerations are increasingly subject to scrutiny. In practice, this means that historic assumptions around domicile, habitual residence, and asset disclosure should be revisited – particularly where structures or arrangements were put in place many years ago. 

Why Early Review Matters 

Identifying overseas assets at an early stage can significantly reduce disruption later in the administration process. Delays commonly arise where foreign assets are discovered after probate has commenced, triggering additional legal work, potential resealing requirements, or unexpected tax exposure. 

Early review enables practitioners to: 

• Clarify the governing law applicable to each asset 

• Confirm whether foreign grants, resealing, or ancillary probate will be required 

• Assess inheritance tax exposure across multiple jurisdictions 

• Identify missing documentation or ownership discrepancies before they become contentious 

From a risk management perspective, it also reduces the likelihood of post-grant challenges, beneficiary disputes, or allegations of incomplete disclosure. 

Non-Dom Reforms and Estate Exposure 

The evolving non-dom regime adds another layer of complexity. Changes to how domicile and long-term residence are assessed may bring overseas assets within scope in circumstances where clients previously assumed protection. 

For estates involving long-term UK or Irish residents with international connections, legacy planning decisions may no longer align with the current legislative environment. This makes early 2026 an opportune time to reassess exposure, particularly where estates involve: 

• Long-held foreign property 

• Offshore investment portfolios 

• Family businesses incorporated overseas 

• Assets held in jurisdictions with differing succession laws 

Without review, estates risk unintended tax liabilities or conflicts between forced heirship rules and testamentary intentions. 

Practical Challenges in Cross-Border Estates 

Even where assets are known, practical difficulties can arise. Overseas institutions may require local documentation, translations, or proof of entitlement that differs from domestic standards. In some cases, beneficiaries themselves may be unaware of their potential entitlement, particularly in intestacy scenarios involving extended family or historic migration. 

This is where early investigation and verification play a vital role – ensuring that all relevant assets and entitled parties are identified before distributions are made. 

“We’re seeing far more scrutiny of overseas assets than ever before. Taking the time to check what exists, how it’s held, and what paperwork is needed at the outset can save a great deal of stress later on. It’s always easier to address these issues early rather than react to them once the estate is already in progress.”
