Estate Planning for Snowbirds and Dual-State Residents: A Long Island and Florida Guide

Estate planning for snowbirds and dual-state residents is the process of structuring your will, trusts, and asset titling so that one legal “home state” (your domicile) controls how your estate is settled and taxed, while property in your second state is handled without a costly duplicate probate. For someone who summers on Long Island and winters in Florida, the central decisions are which state you call home for tax and inheritance purposes, and how you title the house, accounts, and other assets in the state you do not choose. Get those two things right and you can sidestep double taxation, conflicting state laws, and the most common trap of all: a second probate case 1,300 miles from where your family lives.

I have spent years untangling estates for people who split the year between New York and Florida, and the pattern is almost always the same. The planning that worked perfectly while someone was a lifelong New Yorker quietly stops working the day they buy a condo in Naples or Boca and start spending six months a year there. Nobody updates the deed, nobody reconsiders domicile, and the family finds out the hard way. This guide walks through what actually matters.

Why Dual-State Living Complicates an Estate Plan

The United States does not have one set of inheritance rules. Each state writes its own probate code, its own estate and inheritance tax laws, and its own homestead and creditor protections. When you live meaningfully in two states, both of them have a plausible claim to govern parts of your estate. That overlap is where the trouble starts.

Three issues come up again and again for Long Island residents who spend serious time in Florida:

• Domicile disputes. Only one state is your legal domicile, but if your paperwork is sloppy, two states can each argue they are owed estate or income tax. New York is well known for auditing residency aggressively.
• Two probates. Real estate is probated where it physically sits. A New York will does not automatically clear title to a Florida condo, and vice versa, which can force a second proceeding called ancillary probate.
• Conflicting protections. Florida’s homestead protection and New York’s elective-share and spousal rules do not line up. A plan drafted for one state can produce a result you never intended in the other.

Domicile Versus Residence: The Decision That Drives Everything

“Residence” just means a place you live. “Domicile” is your one true legal home, the place you intend to return to and the state whose laws will govern your will and most of your tax exposure. You can have several residences. You can have only one domicile at a time.

This distinction is not a technicality. New York imposes its own estate tax with a relatively modest exemption and a notorious “cliff” that can tax the entire estate, not just the excess, once you exceed the threshold by more than 5%. Florida, by contrast, has no state estate tax and no state income tax. For many snowbirds, formally establishing Florida domicile is the single most valuable estate-planning move available to them. But intent has to be backed by behavior.

How to Establish (and Prove) Florida Domicile

Florida law does not impose a magic number of days, though the practical benchmark people watch is the 183-day line New York uses in its statutory-residency test. What matters is a consistent body of evidence pointing to one home state. If you want Florida to be your domicile, the record should show it:

1. File a Florida Declaration of Domicile with the county clerk where your Florida home sits.
2. Get a Florida driver’s license and register your vehicles in Florida.
3. Register to vote in Florida, and actually vote there.
4. Claim the Florida homestead exemption on your residence (you cannot claim a residency-based exemption in two states).
5. Update your will and trusts to recite Florida domicile, and have them drafted under Florida law.
6. Move banking, primary physicians, and key professional relationships to Florida, and track your days with a calendar or app.

New York auditors look at the whole picture: where your “near and dear” items are, where you spend major holidays, where your business ties are. Keeping a Long Island house is fine. Treating it as your real headquarters while claiming Florida on paper is what gets people caught.

Florida Homestead Protection and How It Interacts With Your Plan

Florida’s homestead is one of the strongest asset protections in the country. Properly claimed, your Florida residence is largely shielded from creditors and carries a property-tax exemption with assessment caps. The protection is rooted in the Florida Constitution and supported by statute.

The catch is that homestead also restricts what you can do with the property at death. Under Florida Statutes § 732.401 and § 732.4015, if you are survived by a spouse or a minor child, you cannot freely devise the homestead to whomever you like. A surviving spouse generally receives a life estate with a remainder to descendants, or may elect a one-half tenancy-in-common interest. If you try to leave the homestead to, say, an adult child from a prior marriage while your spouse is living, the will provision can be void and the statute overrides your wishes.

This surprises blended families constantly. Homestead is a benefit, but it has to be planned around, often using a properly structured trust or a recorded life estate arrangement rather than a bare will provision.

The Two-Probate Problem and Ancillary Administration

Here is the scenario I see most. A Long Island resident keeps domicile in New York, owns the family home in Nassau or Suffolk County, and also owns a Florida condo in their own name. They pass away. The New York estate is probated in Surrogate’s Court. But the Florida condo is real property located in Florida, so New York’s court has no power to transfer its title.

The fix the law provides is ancillary administration under Florida Statutes § 734.102. When a nonresident dies owning Florida assets, liens on Florida property, or debts owed by Florida residents, a secondary Florida probate is opened to deal with those local assets. The personal representative named in the will administers the Florida property if qualified to serve. It works, but it means a second court case, a second set of filings, a second attorney, and more time and cost before the family can sell or transfer the Florida home.

How to Avoid a Second Probate Entirely

The good news is that ancillary probate is usually avoidable with planning done while you are alive. The cleanest tools include:

• A revocable living trust. Deed the Florida property into the trust. Trust assets are not probated at all, in either state, so there is no ancillary case to open. This is the workhorse solution for dual-state owners.
• Enhanced life estate (“Lady Bird”) deeds. Florida recognizes these. They let the property pass automatically at death while you keep full control during life, and they preserve homestead.
• Joint ownership with rights of survivorship, used carefully. It avoids probate but creates exposure to the co-owner’s creditors and can complicate basis and gift-tax issues, so it is not a universal answer.

A trust-centered plan also keeps your affairs private and gives you a single, coordinated document governing assets in both states. If you are weighing whether a trust is right for your situation, the attorneys at Morgan Legal’s New York office walk clients through how revocable and irrevocable trusts fit a dual-state plan, and our overview of wills explains where a will still belongs in the mix.

Coordinating New York and Florida Documents

You generally want one master estate plan, not two competing ones. Two separately drafted wills, one from each state, are a recipe for accidental revocation and contradiction. The better approach is a single will and trust, drafted under the law of your chosen domicile, that expressly accounts for property in the other state.

Your incapacity documents need the same attention. A New York power of attorney uses a statutory short form that Florida banks and title companies sometimes question, and Florida’s durable power of attorney has its own signing and “superpower” initialing requirements. Health care directives differ too. Practically, many dual-state clients execute documents valid in both jurisdictions, or maintain a coordinated set so that whichever state they are in when a crisis hits, the paperwork is honored on the spot. If aging-in-place, long-term care, or Medicaid is on the horizon, looping in an elder law attorney early prevents the disjointed planning that leaves families scrambling.

Taxes: Where Snowbirds Save the Most and Slip the Most

At the federal level there is one estate tax exemption no matter where you live, and the portability election lets a surviving spouse use a deceased spouse’s unused exemption. The state layer is where dual-state status changes the math.

New York’s estate tax can reach estates that owe nothing federally, and the cliff makes crossing the threshold painful. Florida adds no state estate or income tax on top. If you genuinely shift domicile to Florida and own real property in New York, note that New York can still tax New York-situs real estate in a nonresident’s estate, so even Florida domiciliaries should think about how their Long Island house is titled, sometimes holding it through an entity or trust. This is exactly the kind of detail that rewards planning and punishes guesswork.

A Practical Checklist for Long Island Snowbirds

• Decide your domicile deliberately, and align every document, license, and registration with it.
• Re-title or re-deed out-of-state real estate into a trust or appropriate deed to avoid ancillary probate.
• Plan around Florida homestead’s devise restrictions, especially in blended families.
• Maintain coordinated powers of attorney and health directives valid where you actually are.
• Review the plan after any move, marriage, purchase or sale of property, or major tax-law change.

Dual-state estate planning is not complicated because the rules are obscure. It is complicated because two complete legal systems are touching the same family, and the documents have to speak to both. Done well, it is largely invisible: your family inherits smoothly, in one proceeding, with the lower tax bill. Done by accident, it produces the second courtroom, the audit letter, and the void will provision. To get a plan built for the way you actually live, schedule a consultation with an attorney who handles New York and Florida estates together.

Frequently Asked Questions

Can I avoid Florida ancillary probate if I live on Long Island but own a Florida condo?

Yes, in most cases. The most reliable method is to deed the Florida property into a revocable living trust while you are alive, so it is not a probate asset in either state. Florida also recognizes enhanced life estate (Lady Bird) deeds, which pass the property automatically at death while you keep control and homestead during life. Without one of these tools, a nonresident’s Florida real estate typically requires a separate ancillary administration under Florida Statutes section 734.102, in addition to the main probate in New York.

How does Florida decide whether I am a resident for estate purposes?

Florida looks at domicile, meaning intent to make Florida your permanent home, supported by objective evidence rather than a fixed day count. Filing a Declaration of Domicile, getting a Florida driver’s license, registering to vote, claiming the homestead exemption, and updating your will under Florida law all build that record. New York applies its own statutory residency test, often watching the 183-day line, so consistency between the two states matters.

Do I need a separate will for New York and one for Florida?

Usually no, and having two can backfire. Two independently drafted wills risk accidentally revoking or contradicting each other. The cleaner approach is a single, coordinated estate plan drafted under your chosen domicile state’s law that expressly addresses property located in the other state, paired with powers of attorney and health directives that will be honored in both jurisdictions.

Will my heirs pay estate tax in both New York and Florida?

Florida has no state estate tax, so it imposes none directly. New York does, with a low threshold and a cliff that can tax the entire estate once you exceed the limit by more than five percent. Even if you become a Florida domiciliary, New York can still tax New York real estate owned by a nonresident, which is why titling your Long Island property correctly is part of the plan.

What is special about Florida homestead in estate planning?

Florida homestead offers strong creditor protection and property-tax benefits, but it also restricts how you can leave the property at death. Under Florida Statutes section 732.401 and section 732.4015, if you are survived by a spouse or minor child, you generally cannot freely devise the homestead; the surviving spouse receives a life estate or may elect a one-half interest. Blended families especially need to plan around this with a trust or appropriate deed.
