Foreign Executor Authority: How to Act as Executor in Another Country

Your Domestic Appointment Stops at the Border

A US probate grant authorizes you to administer the estate under the issuing court's law. It does not by itself authorize you to transfer a rental property in London, access a bank account in Mumbai, or transfer shares in an Australian company. Foreign institutions may require local recognition, resealing, or a local appointment.

You may need local recognition or authority in each country where the estate holds assets. Some jurisdictions allow an existing grant to be resealed, and the European Certificate of Succession can provide standardized proof of authority across participating EU member states. Which process applies depends on the country.

Option 1: Ancillary Probate

Ancillary probate means opening a second, parallel probate proceeding in the foreign jurisdiction. You petition the local court, present certified copies of the primary grant and the will (apostilled and translated), and the court appoints a local personal representative — either you directly or a local attorney acting on your behalf.

This is a common path for real property in jurisdictions that require a separate local proceeding. If the deceased owned a vacation home in France or a condo in Mexico, a local succession or title-transfer process is generally needed; in civil-law countries such as France, a local notary may manage the succession. The process can duplicate filing fees, require local legal counsel, and add time.

Some US states also require ancillary probate for out-of-state real property. Nevada, for example, mandates a full local proceeding for any real estate within its borders, including timeshares.

Option 2: Resealing (Commonwealth Countries)

If the foreign jurisdiction is part of the Commonwealth — the UK, Australia, Canada, New Zealand, and many Caribbean and Pacific nations — you may be able to use a simplified process called resealing under frameworks like the UK's Colonial Probates Act 1892.

You submit your original grant of probate (or an exemplified copy certified by the issuing court) to the foreign probate registry. Once the local court applies its seal, your existing grant receives the same legal force as a domestic one. No need to re-litigate the will's validity or your appointment.

The key limitation: resealing only works between Commonwealth nations. A US grant cannot be resealed in the UK. And some Crown Dependencies — Jersey, Guernsey, and the Isle of Man — explicitly reject resealing in favor of full independent local applications.

Option 3: Local Appointment

In civil law countries (most of continental Europe, Latin America, parts of Asia and Africa), the system works differently. There's no probate court in the common law sense. Instead, a notary manages the succession process, and ownership often transfers automatically to the heirs by operation of law — a principle known as le mort saisit le vif (the dead seizes the living).

In these jurisdictions, you'll typically need to engage a local notary who will verify your authority through the will, death certificate, and heirship documentation. In participating EU member states, a European Certificate of Succession can serve as standardized proof of heirship and executor powers across borders without requiring an apostille.

What Every Foreign Institution Will Ask For

Requirements vary by institution and jurisdiction. Common requests include:

• Apostilled or legalized death certificate (certified copy from the registrar, not a photocopy)
• Court-sealed letters testamentary or administration. Foreign transfer agents generally require them to be dated within 60 days of submission; New York transfer agents allow six months.
• Sworn translation of all documents into the local language
• Proof of identity — passport, sometimes notarized

Transfer agents may require recently issued letters. Foreign transfer agents generally use a 60-day window, while New York transfer agents allow six months; confirm each receiving institution's rule. If your administration spans months, you may need to request fresh letters from the issuing court.

Co-Executors Across Countries

When a will names co-executors in different countries, local rules may allow an executor's power to be reserved during the primary grant. In jurisdictions with a double-probate procedure, a reserved executor may need to apply separately and provide a copy of the original grant, a marked copy of the will, and an estate account. Requirements differ by jurisdiction; some procedures waive documents already established in the primary filing.

The International Estate toolkit includes a jurisdiction-by-jurisdiction authority matrix, template petitions for ancillary and double probate, and a document authentication tracker to manage submissions across multiple countries simultaneously.
