A move to the United States changes more than the location of your assets. It can change which court handles an estate, how guardianship is addressed, which state law applies and how documents signed in another country work with U.S. property and accounts.
An existing foreign will may remain valid or relevant, but it should not be assumed to manage the U.S. side efficiently. Replacing it without coordinated advice can be just as risky because a new document may unintentionally revoke, contradict or overlook part of the existing plan.
The goal is one coordinated estate plan across countries, even when that plan uses more than one document.
What a U.S. will can do
A will is governed largely by state law. Subject to that law and court oversight, it can:
- Direct who receives assets that pass through probate
- Name the person who should administer the estate
- Nominate guardians for minor children
- Create or fund trusts for children or other beneficiaries
- Give the personal representative appropriate administrative powers
- Change the default inheritance outcome that would otherwise apply
A guardian nomination is important, but the court makes the appointment based on the child’s best interests and applicable law. International families should discuss citizenship, immigration status, location, travel and the practical ability of the proposed guardian to care for the child in the United States.
A will does not control every asset
Many assets pass according to their title or beneficiary form rather than the will. These can include:
- Life insurance
- Retirement accounts
- Payable-on-death or transfer-on-death accounts
- Jointly owned property with survivorship rights
- Assets already held in a trust
The American Bar Association’s beneficiary-designation overview explains why primary and contingent beneficiaries need to be coordinated with the wider estate plan.
Review beneficiary forms after marriage, divorce, a birth, a death, a move or a major account change. Updating the will alone may not change who receives these assets.
Coordinate documents from every country
Prepare a list of every existing will, trust, company, partnership, retirement interest, insurance policy and property holding. Tell each professional which countries and legal systems are involved.
Ask the U.S. and foreign advisers to address:
- Whether the new will revokes all prior wills or only a defined part
- Whether separate wills are sensible for assets in different countries
- How executors or personal representatives can act across borders
- Whether foreign matrimonial or community-property rules affect ownership
- How trusts and companies fit into the succession plan
- What translations, notarisation or witnessing may be needed
Do not sign two documents prepared independently without each adviser seeing the other. Small revocation clauses can create large unintended consequences.
Plan for incapacity as well as death
A will generally takes effect at death. It does not appoint someone to manage your finances or make health decisions while you are alive but unable to act.
| Document | Typical purpose |
|---|---|
| Durable financial power of attorney | Authorises a chosen person to handle defined financial and legal matters |
| Health care directive | Records health care wishes under the applicable state framework |
| Health care proxy or surrogate designation | Names the person who may make health decisions when required |
| HIPAA authorisation | Allows specified people to receive protected health information |
| Temporary guardian or emergency plan | Helps address immediate care for minor children, subject to state law |
The ABA explains how a power of attorney can define who acts and the scope of that authority. These documents should be prepared for the state where you live and reviewed after a move to another state.
Do not confuse immigration, income-tax residence and domicile
Immigration status, income-tax residence and estate-tax domicile are different concepts. A person can have connections to more than one country, and citizenship can affect estate and gift planning.
The IRS provides general information on estate and gift taxes and separate guidance on estate tax for nonresidents who are not U.S. citizens. These pages are starting points, not a substitute for advice on domicile, treaty position, asset situs or transfers to a noncitizen spouse.
Bring the estate-planning conversation into the wider America Financial Readiness review so tax, investment, insurance and ownership decisions do not work against one another.
Create a usable asset and information map
A signed will is difficult to use if the family cannot find the assets or advisers. Create a secure inventory containing:
- Bank, investment and retirement accounts
- Real estate and ownership documents
- Companies, partnerships and trusts
- Insurance policies and beneficiary details
- Loans, guarantees and other liabilities
- Digital assets, subscriptions and key online accounts
- Professional advisers and emergency contacts
- The location of original estate documents
Do not place live passwords in an unsecured spreadsheet. Record how the appointed person can obtain lawful access through a password manager, digital-vault process or instructions agreed with the attorney.
Review the plan after major changes
The ABA’s guidance on updating an estate plan identifies life changes such as marriage, divorce and the birth of a child as review points. International families should also review after:
- Moving to a different U.S. state
- Receiving permanent residence or citizenship
- Buying or selling property
- Opening a business or changing ownership
- Creating or receiving an interest in a foreign trust
- A major change in wealth or insurance
- The death, illness or relocation of an executor, guardian or beneficiary
A practical first-month estate checklist
- Locate and scan every existing will and trust document.
- List assets, ownership, beneficiaries and countries involved.
- Identify the people currently named as executors, trustees, guardians and agents.
- Book a state-licensed estate-planning attorney with cross-border experience.
- Ask how U.S. documents will coordinate with the foreign plan.
- Complete the incapacity and health care documents.
- Store originals safely and tell the right people where they are.
The practical takeaway
A U.S. will is one part of the plan. International families need coordinated wills, beneficiary designations, guardianship nominations, incapacity documents and an accurate asset map. Use qualified attorneys and tax professionals in the relevant jurisdictions, and revisit the plan as status, state, family and ownership change. Estate planning also belongs within the wider Finance & Tax resources and the family planning offered through The New Life Journey.
