Key West has always been a crossroads. With Cuba just ninety miles away and a community shaped by Caribbean, Latin American, and European families, many estate plans here involve heirs who live abroad, spouses who are not U.S. citizens, and beneficiaries whose inheritance can be complicated by a pending visa or green-card case. When inheritance and immigration overlap, the ordinary will or trust is not enough. This article explains where Florida estate planning and federal immigration law intersect, and why newcomers to the Keys often need counsel in both fields.
The Non-Citizen Spouse Problem: QDOT Trusts
One of the most overlooked issues affects married couples where one spouse is not a U.S. citizen. Under federal law, a citizen spouse can leave an unlimited amount to a surviving citizen spouse free of federal estate tax — the unlimited marital deduction. That deduction generally does not apply when the surviving spouse is not a U.S. citizen. Congress was concerned a non-citizen could inherit a large estate and then leave the country before any tax was ever collected.
The standard fix is a Qualified Domestic Trust, or QDOT. Property passes into the trust for the surviving non-citizen spouse instead of outright, and with at least one U.S. trustee and the required IRS provisions in place, the estate tax on the principal is deferred. If your spouse is a lawful permanent resident who has not yet naturalized, this is a planning point you cannot ignore — and one reason to coordinate the estate plan with the citizenship timeline.
Estate Tax Exposure for Non-Resident Heirs and Owners
Non-resident aliens who own U.S. property — a Key West condo, a slip, or a U.S. brokerage account — face a very different estate tax regime than citizens and residents. The exemption available to a non-resident, non-citizen decedent for U.S.-situated assets is far smaller than the exemption available to U.S. persons. Foreign families who buy real estate in the Keys frequently discover this only at death, when the U.S. property triggers a federal estate tax filing. Holding structures and lifetime planning can reduce that exposure, but only if addressed in advance.
How Immigration Status Shapes an Inheritance
Florida law does not bar a non-citizen or an out-of-country heir from inheriting. A beneficiary living in another country can receive assets under a Florida will executed per section 732.502, Florida Statutes, or under a revocable trust governed by Chapter 736. The practical hurdles are logistical: a beneficiary abroad may need to sign documents before a U.S. consulate, provide consular-authenticated identification, or work through an apostille to prove identity and authority. Distributions to certain countries can also raise sanctions or banking-compliance questions. Naming a U.S.-based trustee or personal representative who can manage these consular and cross-border steps keeps the administration from stalling.
Florida’s homestead protections add another layer. Homestead has constitutional restrictions on how the property can be devised when there is a surviving spouse or minor child, and those rules apply regardless of the heirs’ citizenship. A plan drafted abroad or in another state often fails to account for Florida homestead, so a local review is essential.
Guardianship, Powers of Attorney, and Travel for Visa Matters
Immigrant parents in the Keys should name guardians for minor children with extra care, especially where the intended guardian lives in another country or has a different immigration status. The estate plan should designate a guardian and also provide for who manages the child’s inheritance until adulthood.
Powers of attorney matter enormously for families with active immigration cases. Clients frequently travel abroad for consular interviews or visa stamping and may be outside the country for weeks. A durable power of attorney and a health care surrogate ensure someone in Florida can sign closings, manage accounts, and handle emergencies while you are away. If you are abroad when a real estate or business deadline hits, that document is the difference between a smooth closing and a missed one.
Coordinating Your Estate Plan With a Pending Immigration Case
Because this is an estate planning firm and we do not practice immigration law, we coordinate with immigration counsel rather than guess at it. If your plan depends on a spouse’s naturalization, on family green cards for relatives you intend to sponsor and provide for, or on the timing of an adjustment-of-status case, those legal questions belong with an immigration attorney. For our many Russian- and Ukrainian-speaking clients in South Florida, we often suggest working with a Russian-speaking immigration attorney so nothing is lost in translation between the two plans.
The takeaway for anyone new to Florida is simple: an estate plan and an immigration strategy should be built to fit each other. A QDOT trust, a Florida-compliant will, homestead-aware devises, and powers of attorney all work best when they account for where your family members live, what passports they hold, and where their cases stand. If you have heirs overseas or a non-citizen spouse, talk to a Key West estate planning attorney — and the right immigration counsel — before, not after, life changes.
