Why this update matters
When you move to a different state or change your citizenship, you change the legal environment that governs your property, taxes, and end-of-life decisions. State laws control probate procedures, homestead protections, creditor rights, community property rules, and how personal property is characterized. National status (citizen, resident alien, nonresident alien) affects federal tax treatment of your worldwide assets, the availability of marital deductions, and whether special trusts or filings are required. For these reasons, an estate plan prepared in one jurisdiction can produce unintended and costly results after a major relocation or citizenship change.
In my 15+ years as a Certified Financial Planner (CFP®), I’ve seen clients lose time and money by assuming that a prior estate plan “just works” after a move. Updating documents proactively is one of the highest-value planning steps you can take.

Key documents to review or update
-
Will: State law affects how a will is interpreted and what formalities (signatures, witnesses, notarization) are required. A will valid in one state may need updating to avoid ambiguity or challenges.
-
Revocable living trust: Trusts are generally portable, but funding (moving titles into the trust) and state trust law differences can change administration and tax results.
-
Beneficiary designations: Retirement accounts, life insurance, and transfer-on-death registrations (TOD) often pass outside the will. Confirm that beneficiaries match your current intentions and comply with the new jurisdiction’s rules.
-
Powers of attorney (financial and medical): These documents are state-specific. A health care proxy or durable power of attorney executed in one state may not be recognized in another.
-
Deeds and property titles: Real estate follows local rules. A homestead election or community-property designation may offer protections or consequences you should account for.
-
Trusts for noncitizen spouses (QDOTs): If you have a noncitizen spouse, special trust structures such as a Qualified Domestic Trust (QDOT) may be needed to preserve estate-tax benefits (IRS guidance on QDOT).
-
Estate tax filings and portability elections: If applicable, timely estate tax returns and portability elections can preserve federal exclusion amounts for a surviving spouse.
Residency, domicile, and tax residency—what to watch for
Two different concepts are essential:
-
Domicile (legal residence): Where you intend to make your permanent home. Domicile determines which state’s probate court has primary jurisdiction and often which state’s estate or inheritance taxes may apply.
-
Tax residency (state and international): States use different tests for residency (days present, driver’s license, voter registration, intent). For U.S. federal tax, U.S. citizens and resident aliens are taxed on worldwide income; nonresident aliens are taxed differently and may face U.S. estate tax on U.S.-situated assets.
Document changes that evidence your new domicile can help avoid disputes later — update voter registration, driver’s license, state income tax filings, and real property records where appropriate.
(See IRS guidance and state tax authorities for residency rules.)
Practical tax implications to consider
-
State estate vs. inheritance taxes: A few states impose estate taxes, and some have inheritance taxes. After moving, the presence or absence of those taxes may change whether you need a tax plan in the new state.
-
Federal estate tax and portability: Federal law changes periodically. Portability (the transfer of a deceased spouse’s unused exclusion to the surviving spouse) is available only if an estate tax return is timely filed. If your relocation affects where you file or who serves as executor, coordinate to preserve portability.
-
Noncitizen spouses and marital deduction limits: The unlimited marital deduction that shelters a transfer to a U.S. citizen spouse from estate tax does not automatically apply to transfers to a noncitizen spouse. A QDOT can preserve tax-deferred treatment but requires trustee and reporting rules (IRS: QDOT rules).
-
International tax treaties and foreign reporting: If you or beneficiaries live abroad, foreign tax treaties, reporting obligations, and local estate or inheritance tax rules can create double taxation risks. Work with cross-border tax counsel when global assets are involved.
Cross-border and multistate complications
If you own property in more than one state or country, you may face multiple probate proceedings or ancillary administrations. Immovable property (real estate) is typically governed by the jurisdiction where it sits; personal property (bank accounts, securities) often follows the domicile law. Some civil-law countries have forced heirship rules that override testamentary freedom; U.S. estate documents may have limited effect in those places.

A practical checklist after a move or citizenship change
-
Confirm your new domicile and update government records: driver’s license, voter registration, state income tax filings, and address on federal tax returns.
-
Review your will and revocable trust. Ensure the executor/trustee is willing and able to serve in the new jurisdiction.
-
Update powers of attorney and health care directives to state-compliant forms.
-
Review beneficiary designations on retirement accounts, life insurance, TOD/POD registrations, and payable-on-death accounts.
-
Re-title real estate and tangible property if necessary to align with trust funding or local homestead rules.
-
Check for state estate or inheritance taxes and model potential tax bills with a planner or attorney.
-
If you have a noncitizen spouse or beneficiaries abroad, consult an international estate planner about QDOTs, tax treaties, and local inheritance rules.
-
Revisit life insurance, long-term care, and special needs planning that may be affected by state law.
-
Inform trusted family members and professional advisors of the changes and share updated document locations and access instructions.
Common mistakes to avoid
-
Assuming a will or power of attorney executed elsewhere will be fully valid in your new state.
-
Forgetting to update beneficiary designations, which override a will in many cases.
-
Overlooking small-asset probate thresholds and local filing requirements that can force probate in multiple states.
-
Not considering the marital-deduction rules for noncitizen spouses and failing to establish a QDOT when beneficial.
-
Waiting too long to file necessary estate tax returns (and losing portability) or to retitle assets into a trust.
Professional strategies and best practices
-
Review your estate plan within 6–12 months after a major move or citizenship change. I usually recommend a formal review meeting to confirm domicile evidence, beneficiaries, and trustee/executor choices.
-
Use local counsel for statutory documents (powers of attorney, health directives). Use a federal or cross-border specialist for international tax and treaty questions.
-
Make a prioritized short list of immediate updates (healthcare POA, beneficiary designations, driver’s license, deed) and a longer checklist for trust funding and tax planning.
-
Keep digital copies and clear instructions for heirs. For digital-asset specifics, see our article on Digital Estate Planning: Managing Online Accounts and Assets.
FAQs (brief answers)
Q: Do I need a new will after moving to another state?
A: Often yes — at a minimum, review it with local counsel to confirm validity and interpretation under the new state’s law.
Q: Will my trust protect me after I move?
A: Trusts generally remain effective, but funding, trustee selection, and state trust law differences can change how they operate.
Q: Does a citizenship change affect federal taxes on my estate?
A: Yes. U.S. citizens and resident aliens are taxed differently from nonresident aliens. Citizenship changes may also change reporting obligations and estate tax exposure. Consult tax counsel.
Final takeaways
Updating your estate plan after a major relocation or a change in citizenship isn’t optional — it’s a practical and often inexpensive step to avoid real harm to beneficiaries. The right updates protect your wishes, reduce probate friction, and limit tax surprises. Start with the basic checklist, update immediate documents, and consult specialists for complex tax or cross-border matters.
