What Korean Heirs Face When Parents Hold Assets Across Multiple Countries

There is a sentence I hear often in consultations. "I heard my father had assets in the United States, Brazil, and Singapore, but I have no idea where to begin." While the parent was alive, they managed everything personally, and life moved on without any special procedures. The moment death occurs, however, the heirs are confronted head-on with foreign procedures and costs they have never had to deal with. This article walks through the issues most commonly encountered in cross-border inheritance, and the items that — typically — reduce the post-mortem burden dramatically if they are put in order while the parent is still healthy.

If recovering domestic deposits isn't simple, abroad is even harder

Even when heirs are in full agreement, the procedure for withdrawing domestic deposits in Korea is not simple. Financial institutions typically require strict documentation: consent of all heirs, identity documents, family relationship certificates, basic certificates, death certificates, and the inheritance property partition agreement.

When the assets are abroad, all of these procedures are repeated in that country's law and language. The following typically need to be prepared in addition.

• Translation and notarization of Korean documents into the foreign language
• Apostille or consular legalization
• The country's own probate or inheritance certification procedure
• Local tax filing and payment
• Retaining local attorneys and accountants

Sometimes the cost structure catches up to the value of the asset

A common trap in cross-border inheritance is when recovery costs approach or exceed the value of the asset itself. Suppose the deceased left roughly KRW 20–30 million in deposits in Brazil. The cost of recovering those deposits — preparing documents in both Korea and Brazil, translation and notarization, local attorney fees, remittance fees, exchange-rate effects — can almost catch up to the value of the asset.

Two pre-mortem cleanup strategies

When a parent is still healthy, there are typically two pathways for setting up.

• First: During lifetime, repatriate or wind down foreign assets, leaving only domestic assets behind
• Second: Design an inheritance-automation structure such as a trust under the local law

In countries like the United States, where the trust system is well developed, structures such as a living trust or revocable trust can be designed so assets transfer automatically to the beneficiary upon death. This typically allows the probate procedure itself to be bypassed, saving both time and cost.

That said, trust design must be done with local attorneys and accountants in that country, and tax and inheritance relationships with Korea must also be sorted out. Working with an attorney familiar with both jurisdictions is typically the safer route.

Five things adult children should check first

If you know that your parents also hold assets abroad, I recommend reviewing the following five items.

• An asset list (asset type, amount, account number, registry number — broken out by country)
• Contact information for local custodians (private bankers, attorneys, accountants)
• The legal form in which assets are held (individual name, corporate name, trust, etc.)
• The inheritance and gift tax structure of that country and whether the Korean tax law's double-taxation adjustment applies
• Who will be notified by what procedure upon death (death-registration synchronization)

Without these five items in order, it typically takes heirs years just to locate the assets after death.

A combined strategy I often recommend as counsel

As counsel, when handling cross-border inheritance matters, I tell clients that a structure in which everything can be wrapped up in Korea is typically the safest. The following combination tends to be effective.

• A Korean notarized will plus a Korean attorney designated as executor
• Country-by-country, advance dispositions (trusts, gifts, etc.) tailored to the local law
• A check of both countries' tax-filing obligations in advance so the post-death filing deadlines are not missed

This work is only possible while the parent is healthy. Once consciousness has weakened, it typically becomes difficult to carry out.

Frequently asked questions

Q. My father holds real estate abroad. Should we sort it out while he is still alive? A. The asset value, recovery difficulty, and the tax structure of both countries need to be reviewed together. "Sort it out now" is not the answer in itself — the question is the form in which to leave it. For a concrete situation, I recommend chatting with us now.

Q. If a foreign trust is set up, will it also be recognized in Korea? A. The trust itself has its effect in that country, but Korean inheritance and gift tax treatment must be reviewed separately. The point at which a trust is taxed under Korean tax law may differ from ordinary inheritance.

Q. What if we learn only after death that there are assets abroad? A. The procedures typically get longer, but it is not impossible. It is important to start the cleanup before the local statute of limitations applies.

Closing

Cross-border inheritance is an area where the complexity of procedures is a bigger burden than the value of the assets. Sorting things out while a parent is healthy typically reduces the post-mortem time and cost significantly. If you are not sure which countries your family's assets are spread across, I recommend starting with a check.
