Max Gerstein on US Situs Risk and the Loss of Financial Control

 

US Situs Risk Isn’t a Tax Problem. It’s a Control Problem

Understanding the real risk behind US assets for non‑US individuals

For clarity:
US situs risk refers to the legal and jurisdictional exposure that arises when a non‑US person owns US‑based assets such as US stocks, ETFs, funds, brokerage accounts, or property. For international families and expats, this risk is rarely just about tax. It is about what happens to control, access, timing, and liquidity when those assets pass through legal and administrative systems after death.

Most people hear “US situs” and think estate tax. That’s understandable, because tax is the visible part of the conversation. But it isn’t the real risk.

Tax is simply the invoice at the end of a process. The real risk happens earlier, inside the structure. It shows up in who controls access, who controls timing, and who controls decisions when an estate event occurs.

This is what Option Decay looks like in real financial life. Not the slow erosion of returns, but the erosion of choice. Fewer options. Narrower pathways. More friction. Less control over outcomes.

When a non‑US person holds US assets, they are not just holding investments. They are placing part of their wealth inside a foreign legal framework, a foreign probate environment, and a foreign compliance system that their family will one day be required to navigate. At that point, assets stop behaving like portfolio holdings and start behaving like legal objects. They become governed by procedures, timelines, and institutions that have nothing to do with the strategy that created the wealth in the first place.

The uncomfortable truth is simple: families do not just inherit assets. They inherit the process attached to those assets.

The first failure point: liquidity

Most estates are not sitting on large pools of idle cash. They are invested by design. Portfolios are built to grow, not to sit liquid. When obligations arise, whether tax, legal, or administrative, liquidity must be created.

In reality, that often means selling assets.

Not when markets are favourable.
Not when planning would choose to.
Not when families are emotionally ready.

It happens under time pressure, under administrative constraints, and under procedural deadlines. The priority becomes speed, not quality of decision‑making.

This is forced liquidity risk. It is structure‑driven, not market‑driven. It is option decay in motion: fewer choices, worse timing, more dependency on systems rather than strategy.

The second failure point: jurisdiction

Once US assets fall into a US estate process, families are no longer dealing with a single tax liability. They are dealing with systems. Documentation requirements. Procedural sequencing. Compliance processes. Court involvement. Administrative controls. Delays in access.

Money does not move at the speed of grief. Institutions move at the speed of procedure.

Families do not control those timelines. They cannot accelerate them. They cannot bypass them. And they cannot simply rely on intent or expectation to solve them.

This is why control matters more than cost. Outcomes are shaped by process long before they are shaped by numbers.

Why this risk is amplified for expats

For expats and internationally mobile families, this exposure is structurally higher.

Their financial lives are spread across multiple countries, platforms, legal systems, and regulatory regimes. Multiple accounts. Multiple providers. Multiple jurisdictions. Fragmented structures.

It is common to see well‑constructed portfolios sitting on top of poorly integrated structures. Assets are diversified, but control is fragmented. Strategy exists, but architecture does not.

Portfolios are built carefully. Structures often aren’t.

Without a unified estate and jurisdictional framework, complexity creates fragility. What looks sophisticated on paper becomes vulnerable in reality.

The core reframe

US situs risk is not primarily a tax problem.

It is a control problem.
A timing problem.
A liquidity problem.
A jurisdiction problem.
A structural problem.

Tax is simply the most visible layer. Structure is what determines whether families retain options or lose them.

If there is one principle to remember, it is this:

The risks that destroy outcomes rarely show up in performance reports. They show up in process.

US situs exposure is not dangerous because of what it costs. It is dangerous because of what it controls.

Key structural risks of US situs exposure for non‑US persons

• Forced asset sales to create liquidity during estate events
• Loss of control over timing and access to assets
• Jurisdictional lock into US legal and administrative systems
• Delays that affect beneficiaries’ ability to act
• Structural fragmentation across countries and platforms
• Increased complexity and execution risk at the worst possible moment

Core principle:
US situs risk is not primarily a tax exposure. It is a structural exposure, where jurisdiction and process reduce optionality and control.
