Do You Need More Than One Will is designed for families owning assets or living in more than one country. The objective is not to produce a universal answer from a checklist. It is to organize the facts, sequence the decisions, and identify where current country-specific tax, legal, immigration, investment, or benefit advice is required. Use the guide as a working agenda: write down the countries and people involved, add the relevant dates, connect every account and document to its legal owner, and assign each open question to a qualified professional. Because rules and institutional policies change, confirm material conclusions against current official guidance before acting.
Inventory assets and probate jurisdictions
Inventory assets and probate jurisdictions should be treated as a decision with an owner, a deadline, and a written conclusion—not as a box to check. For families owning assets or living in more than one country., the useful starting point is a one-page fact pattern showing the people, countries, dates, accounts, assets, income streams, and documents involved. Record what is known, what is assumed, and what still needs confirmation. That discipline makes it easier to see whether the same fact is being described differently by a bank, employer, immigration adviser, tax preparer, or lawyer.
The cross-border complication is that two systems may classify the same event in different ways or recognize it at different times. A move, payment, contribution, distribution, gift, sale, or ownership change can therefore affect citizenship, domicile, family relationships, asset location, document recognition, transfer taxes, and the people responsible for administration at once. Start with the domestic rules in each relevant country, then ask whether a treaty, social-security agreement, or local election changes the result. A treaty can coordinate taxing rights without eliminating registration, filing, withholding, or information-reporting obligations, so each layer should be documented separately.
A practical review should review this issue before the earliest relevant residence or transaction date. Gather account statements, contracts, tax returns, benefit summaries, immigration records, property documents, and correspondence that establish the facts. Ask each professional to state the scope of the answer: which person, country, tax year, asset, and transaction it covers. If advice depends on a threshold, exchange rate, filing deadline, or special program, verify the current rule with an official source and date the conclusion. Compare keeping the current arrangement, changing it before the relevant date, and waiting until the facts are clearer. Record tax, cash-flow, compliance, access, cost, and reversibility for each path.
- Facts to confirm: who owns or controls the relevant account, asset, benefit, document, or entity
- Dates to record: residence changes, payments, vesting, purchases, sales, filings, renewals, and planned travel
- Questions to assign: which adviser or institution will provide the written answer and by when
- Evidence to retain: statements, valuations, elections, receipts, official guidance, and the final decision log
