  2. Step 2Bring in family and succession professionals in each country.
  3. Step 3Set out options that work in every relevant country.

What is needed varies by country and by matter. Your WONE Global professional confirms the work, timing and fees before anything starts.

Across borders

Complications to check

Issues to assess when more than one country is involved. They are prompts, not conclusions about any country's law.

  • Different laws of contractParties sign one commercial agreement but disagree which law governs duties, damages and remedies
  • Foreign ownership of landAn asset buyer needs to verify permitted ownership interests and registrations
  • Child custody and relocationFamily members live in different countries and dispute applicable forum or orders
  • Court vs arbitration forumAgreement uses arbitration while assets and key witnesses are in different countries
  • Recognition of judgmentsA party wins abroad but needs lawful local recognition and enforcement
