How to Settle an Estate With Assets in Multiple Countries Without Overpaying for Legal Help

The default path for settling an international estate — handing everything to a private client law firm — can involve substantial professional fees across jurisdictions. Private-client legal rates are often $350–$600 per hour. Much of the work is administrative coordination: ordering apostilled death certificates, tracking which transfer agents accept Letters Testamentary dated within 60 days versus six months, filing IRS Form 3520 when a US person receives foreign inheritances totaling over $100,000 in a single calendar year, and sending monthly updates to co-heirs in three countries. Separating this work can help reserve attorney time for matters that require legal judgment.

The way to settle a cross-border estate without overpaying is to split the work into two layers: the legal layer (court filings, forced heirship defenses, treaty elections) that genuinely requires an attorney, and the administrative layer (document authentication, tax compliance checklists, institutional communication, family coordination) that you handle yourself with a structured system.

The Two-Layer Approach

Most executors don't realize how much of cross-border estate settlement is administrative rather than legal. Here's the split:

Tasks that require an attorney:

• Filing ancillary probate petitions in foreign jurisdictions where real property exists
• Defending against or asserting forced heirship claims under civil law (France, Germany, Spain, Italy)
• Making Brussels IV nationality elections when the chosen law is being challenged
• Appearing in foreign court proceedings
• Negotiating treaty-based tax elections on Form 706-NA when the pro-rata unified credit calculation is complex
• Providing binding legal opinions on domicile determinations when two countries claim the deceased

Tasks that don't require an attorney:

• Identifying and inventorying assets across all jurisdictions
• Determining whether each document needs a Hague apostille or full consular legalization
• Ordering certified copies of the death certificate (10–15 is the recommended number for multi-country estates)
• Getting a Medallion Signature Guarantee as a foreign executor
• Filing IRS Form 3520 (information return when a US person receives foreign inheritances totaling over $100,000 in a single calendar year)
• Filing FBAR when the aggregate maximum value of foreign accounts exceeds $10,000 at any point during the calendar year
• Communicating with foreign banks, transfer agents, and pension administrators
• Tracking cascading deadlines across jurisdictions
• Keeping co-heirs informed with structured monthly updates
• Documenting decisions in a contemporaneous log for fiduciary protection

The second list is longer. It's also where executors spend the most time and — when they hand it all to an attorney — the most money.

Step 1: Map Every Asset Before You Call Any Attorney

The single most expensive mistake in cross-border estate administration is hiring an attorney before you know what you're dealing with. At $500/hour, 3–5 hours spent gathering this information would cost $1,500–$2,500: which countries hold assets, what type (real property, bank accounts, securities, pensions, insurance), and what the approximate value is.

The International Estate toolkit includes a Global Asset Inventory Worksheet that captures every account, property, and policy across every jurisdiction — with columns for the governing legal system, authentication requirements, and local counsel contact information. Complete this first. It becomes the intake document you hand to any attorney you hire, reducing the time they spend collecting those details.

If preparing the inventory avoids those 3–5 hours of intake work at $500/hour, that is $1,500–$2,500 per jurisdiction.

Step 2: Handle Document Authentication Yourself

Getting documents authenticated for cross-border use is procedural, not legal. But it's also where most executors lose weeks — submitting the wrong type of certification, missing a validity window, or not realizing that a country requires consular legalization rather than a Hague apostille.

The rules aren't complex, but they're specific:

• Hague Apostille Convention (130 contracting parties as of June 30, 2026): where the Convention is in force between the issuing and destination states, obtain an apostille from the issuing authority's designated competent authority (Secretary of State in most US states)
• Where the Convention does not apply: full consular legalization through the foreign country's embassy or consulate
• Translations: some jurisdictions accept certified translations from any qualified translator; others require sworn translations by a court-appointed translator
• Validity windows: Letters Testamentary must typically be dated within 60 days for most transfer agents (6 months in New York)

A structured document authentication tracker tells you exactly which path each document needs to take in each jurisdiction. Without one, you're paying your attorney $350–$600 per hour to research the same information.

Step 3: File Your Own Tax Disclosures

IRS Form 3520 is an information return — you're reporting the receipt of a foreign inheritance, not computing a tax liability. The inheritance itself is not subject to US income tax, but filing the information return is still required. The penalty for late filing is 5% of the gross inheritance per month, up to 25%. On a $400,000 inheritance, that's $20,000 for each month the failure continues, up to a $100,000 cap.

Many executors pay a CPA or attorney $1,000–$3,000 to prepare Form 3520 because they're afraid of making a mistake. The form itself is straightforward if you have the right checklist: the inheritance amount, the foreign estate's identifying information, and the date of receipt. A structured filing checklist with the thresholds and deadlines keeps you compliant without the professional fee.

FBAR (FinCEN Form 114) is required when the aggregate maximum value of foreign accounts exceeds $10,000 at any point during the calendar year; it's filed electronically, has no fee, and is due April 15 with an automatic extension to October 15.

The one exception: if the estate triggers Form 706-NA (US-situs assets over $60,000 for a decedent who was neither a US citizen nor domiciled in the US) and involves treaty-based pro-rata unified credit elections, hire a cross-border tax CPA. The treaty math is genuinely complex, and the savings from a correct election dwarf the professional fee.

Step 4: Use Scripts for Institutional Communication

When a foreign bank receives a death notification, the quality of that initial communication determines whether your case moves forward in weeks or sits in a compliance queue for months. Generic domestic templates don't work — they lack the formality and specificity that foreign compliance departments expect.

Pre-written scripts for the four critical institutional communications — death notification, account freeze request, securities transfer initiation, and pension/insurance claim — save more time than any other single tool. They're written for the compliance context, not the customer service context, which is the distinction most executors miss.

This is administrative work. Your attorney would draft the same scripts and bill you 2–3 hours for them.

Step 5: Keep Co-Heirs Informed on a Schedule

The most common reason cross-border estates end up in litigation isn't a legal dispute — it's a communication failure. When co-heirs in different countries don't hear from the executor for six weeks, they fill the vacuum with suspicion. By the time the executor sends an update, the damage is done.

A monthly written update — sent on the same day every month, covering progress, next three actions, decisions needing input, and a tax-clearance status reminder — costs nothing and prevents the family conflict that can add $20,000–$100,000 in litigation costs.

The toolkit's Family Communication Schedule Template locks this cadence at the first family meeting. Use it.

The Math

For a two-country estate (US + one foreign jurisdiction) with financial assets and no real property abroad:

The timeline doesn't change dramatically because most delays are institutional (foreign banks processing transfers, courts scheduling hearings), not executor-dependent. But the cost difference is significant.

Who This Is For

• Executors who have been quoted $15,000+ by a cross-border law firm and want to understand which parts of that quote they can handle themselves
• Families settling a two-to-four country estate where the assets are primarily financial (bank accounts, brokerage positions, pensions, insurance)
• US persons whose foreign inheritances totaled over $100,000 in a single calendar year and who need a compliant filing path without a $2,000 CPA bill
• Anyone whose transfer agent rejected their documents and they're about to pay an attorney $500/hour to figure out what a Medallion Signature Guarantee is

Who This Is NOT For

• Estates with contested wills or active forced heirship claims — you need litigation counsel, and cutting costs here is false economy
• Executors who aren't willing to do the administrative work themselves — the savings come from separating admin from legal, not from avoiding work entirely
• Very high-value estates ($10M+) where the tax planning complexity justifies a dedicated private client team

Frequently Asked Questions

Is it risky to handle cross-border estate admin without an attorney?

The administrative tasks — document authentication, tax disclosure filings, institutional communication — are procedural. They have right answers and wrong answers, and a structured checklist gives you the right ones. The risk is in the legal tasks (court filings, forced heirship defenses), which is why the two-layer approach keeps attorneys where they add value and removes them from where they don't.

What's the single biggest cost savings?

Completing the asset inventory and document tracker before engaging any attorney. This can reduce billable intake time. At $500/hour, avoiding 3–5 hours would save $1,500–$2,500 per country.

Can I file Form 3520 myself if the inheritance is $500,000?

Yes. Form 3520 is an information return regardless of the inheritance amount. The form asks for the same fields whether the amount is $101,000 or $5,000,000. The penalty for not filing is the same percentage (5% per month). If you can follow a checklist, you can file it yourself. The toolkit includes the complete filing checklist with every required field and supporting document.

What if the estate includes real property abroad?

Real property in a foreign jurisdiction triggers ancillary probate in that country's courts — you need a local attorney for this. But the surrounding administrative work (document authentication, tax filings, institutional communication for financial assets) still follows the toolkit path. Hire the attorney for the court filing; handle everything else yourself.
