Cross-Border Estates: What to Check

How to handle non-UK assets and residence questions without breaking your UK filing flow.

Back to all guides

When this guide applies

Use this guide if the estate has one or more of these:

  • property, accounts, or investments outside the UK
  • beneficiaries based abroad
  • uncertainty about UK residence or domicile treatment

Cross-border cases often take longer because more than one legal or tax framework may apply.

Cross-border workflow in Estate Suite

  1. In Assets, tag non-UK assets clearly and include jurisdiction details.
  2. In Documents, upload ownership records and valuations for each foreign-linked item.
  3. In IHT, record unresolved cross-border points as open issues before submission.
  4. In Tasks, set dated follow-ups for missing evidence and external advice responses.
  5. In Correspondence, keep communication with overseas institutions in one thread per institution.
  6. Before filing, verify the tax treatment notes match the evidence you uploaded.

Date rule to keep in view

From 6 April 2025, GOV.UK guidance references long-term UK residence rules when deciding UK IHT scope.

If the estate crosses this date or has mixed facts, avoid assumptions and verify with current guidance.

Common mistakes to avoid

  • Filing while foreign ownership evidence is incomplete
  • Recording values without currency/date context
  • Treating advice from one country as automatically valid in another
  • Closing unresolved tax questions too early

FAQ

Why does cross-border work need early review?

It changes scope, timelines, and often the evidence needed for tax and probate.

Can I continue other estate work while cross-border questions are open?

Yes. Keep progressing, but do not finalize filing decisions that depend on unresolved cross-border treatment.
