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 coordinating your will, trusts, powers of attorney, and property titles across two states so that one state’s laws govern your estate cleanly and the other can’t drag your heirs into a second probate. For people who split the year between Long Island and Florida, the central decision is choosing a legal domicile, then making every document and property title consistent with that choice. Done right, it can save your family a second court proceeding, lower your tax exposure, and prevent a fight over which state’s rules apply.

I’ve handled enough estates straddling New York and Florida to know where the trapdoors are. The person who owns a house in Nassau County and a condo in Palm Beach rarely realizes that the two states disagree on almost everything that matters: income tax, estate tax, homestead protection, spousal rights, and what makes a will valid. This guide walks through how to plan when your life — and your real estate — lives in two places.

Why Dual-State Residency Complicates an Estate Plan

Each state wants to tax you and probate your assets. When you keep ties to both New York and Florida, both states may claim you as a resident, and that ambiguity is what causes trouble. The most common problems I see fall into a few buckets:

• Two probates. Real estate is governed by the law of the state where it sits. A New York will still has to clear the New York Surrogate’s Court for the Long Island house, and a separate “ancillary” probate in Florida for the condo.
• Conflicting domicile claims. New York is aggressive about residency audits. If you say you’re a Floridian but spend half the year on Long Island, the New York Department of Taxation and Finance may disagree and tax your worldwide income.
• Document validity. A power of attorney or health care directive that’s perfect under New York law may be questioned by a Florida hospital or bank, and vice versa.
• Homestead surprises. Florida’s homestead protections are unusually powerful — and unusually restrictive about who you can leave the home to.

Domicile vs. Residency: The Decision That Drives Everything

You can have many residences but only one domicile. Domicile is your true, fixed, permanent home — the place you intend to return to. It determines which state’s law governs your will, your intangible personal property (bank and brokerage accounts), and, critically, your income and estate tax.

For most snowbirds, Florida is the better domicile. Florida imposes no state income tax and no state estate or inheritance tax. New York, by contrast, has a state estate tax with a “cliff”: once your taxable estate exceeds roughly 105% of the New York exclusion amount, you lose the exclusion entirely and the whole estate is taxed. That cliff alone has cost New York families enormous sums.

How to Establish Florida Domicile (and Survive a New York Audit)

Intent matters, but New York auditors look at conduct. To make a Florida domicile stick, take concrete, dated steps:

1. File a Declaration of Domicile with the clerk of the Florida county where you live (authorized under Florida Statutes §222.17).
2. Apply for the Florida homestead exemption on your Florida home (more on this below).
3. Get a Florida driver’s license and register your vehicles in Florida.
4. Register to vote in Florida and actually vote there.
5. Update your estate documents to recite Florida domicile and be executed under Florida formalities.
6. Spend fewer than 183 days in New York and keep a contemporaneous record — calendars, credit card receipts, cell phone records, E-ZPass logs. Auditors count days, and the burden of proof falls on you.
7. Move the center of your financial and social life south: primary physician, accountant, house of worship, club memberships.

One day-count caveat that catches people: under New York’s “statutory residency” rule, you can be taxed as a New York resident even with a Florida domicile if you maintain a “permanent place of abode” in New York and spend more than 183 days there. Keeping the Long Island house doesn’t disqualify you from Florida domicile, but it raises the stakes on your day count.

Florida Homestead: Powerful Protection With Strings Attached

Florida’s homestead law is three different things at once, and dual-state owners need to understand all three.

1. Creditor Protection

Under Article X, Section 4 of the Florida Constitution, your Florida homestead is protected from most creditors without dollar limit — only the lot-size acreage is capped (one-half acre within a municipality, up to 160 acres outside one). This is one of the strongest debtor protections in the country and a real reason wealthy New Yorkers establish Florida domicile.

2. Property Tax Relief

The homestead tax exemption under Florida Statutes §196.031 reduces your assessed value, and the “Save Our Homes” cap under §193.155 limits annual increases in assessed value to 3% or the change in the CPI, whichever is lower. You only get these benefits on your permanent residence — you cannot claim homestead in Florida and a STAR exemption in New York at the same time.

3. Restrictions on Who Inherits It

Here is the part that derails estate plans. If you are survived by a spouse or minor child, the Florida Constitution restricts how you can devise your homestead. You generally cannot leave it outright to anyone other than your spouse if you have a minor child, and an improper devise is simply void — the property passes by the statutory default instead. If you have a surviving spouse and no minor children and try to leave the home to someone else, the spouse takes a life estate (or can elect a one-half interest). I’ve seen carefully drafted plans collapse because the drafter treated the Florida condo like any other asset. It isn’t.

Avoiding Ancillary Probate With a Revocable Living Trust

The cleanest way to keep your Long Island and Florida homes out of two separate court proceedings is a properly funded revocable living trust. You transfer title to both properties into the trust during your lifetime. At death, the successor trustee distributes them under the trust terms — no Surrogate’s Court in New York, no ancillary administration in Florida.

A few practical notes for dual-state owners considering trusts:

• Funding is everything. An unfunded trust is just paper. The deeds for both homes must actually be re-recorded into the trust.
• Deeding a Florida homestead into a trust must be done carefully so you don’t lose the homestead tax exemption or creditor protection — Florida permits homestead to be held in a properly structured revocable trust, but the language matters.
• A trust also gives you privacy and a ready mechanism for incapacity, which matters when you’re a thousand miles from one of your homes for half the year.

For families with larger estates, irrevocable trust strategies can layer on top of the revocable trust to address the New York estate tax cliff and to do long-term care and Medicaid planning. If you keep meaningful ties to New York, it’s worth speaking with a firm that handles both sides; Morgan Legal’s New York team covers both and that snowbirds frequently overlook. For the Florida side of the same plan, their Florida estate planning practice coordinates homestead and domicile matters.

Wills, Powers of Attorney, and Health Directives Across State Lines

A will validly executed in one state is generally honored in another, but “generally” is doing heavy lifting. Rather than rely on reciprocity, I recommend re-executing your core documents under the formalities of your domicile state once you make the switch. Florida requires two witnesses for a will and offers a “self-proving affidavit” that lets the will be admitted without tracking down witnesses years later.

Powers of attorney are the bigger headache. A bank or brokerage in one state may balk at an out-of-state form, especially older ones. Florida’s durable power of attorney statute (Florida Statutes Chapter 709) requires specific formalities — two witnesses and a notary — and is “springing”-unfriendly compared to New York’s. If you split your life between the two states, consider executing a power of attorney and health care surrogate designation valid in each state, or at minimum one in your domicile state that institutions in both states will accept. You can review the basics of will requirements on our wills page, and if either home goes through court, our overview of Florida probate explains what your family would face.

A Practical Sequence for Snowbirds Getting Their Plan in Order

1. Decide your domicile deliberately — usually Florida for tax reasons — and document the switch.
2. Claim the Florida homestead exemption and drop any conflicting New York residency-based exemptions.
3. Re-execute your will, powers of attorney, and health directives under your domicile state’s formalities.
4. Create and fully fund a revocable living trust holding both properties to avoid two probates.
5. Check that your homestead devise complies with Florida’s spousal and minor-child restrictions.
6. Keep meticulous day-count records every year you maintain a New York home.

None of this is one-size-fits-all. The right structure depends on the size of your estate, whether you have a spouse or minor children, how much time you actually spend in each state, and what you own beyond the two homes. If you split your year between Long Island and Florida, a short planning conversation now is far cheaper than the probate, tax, and family conflict that a mismatched plan creates later. Reach out to review where your current documents leave gaps.

Frequently Asked Questions

Should snowbirds choose Florida or New York as their legal domicile?

For most snowbirds, Florida is the more advantageous domicile because it has no state income tax and no state estate or inheritance tax, while New York imposes a state estate tax with a steep ‘cliff.’ The choice still depends on how much time you actually spend in each state and where your financial and personal ties are strongest, since New York can tax you as a statutory resident if you keep a permanent home there and spend more than 183 days in the state.

Will my New York will be valid in Florida?

A will validly executed in another state is generally recognized in Florida, but relying on reciprocity is risky. It’s safer to re-execute your will under Florida’s formalities — two witnesses plus a self-proving affidavit — once Florida becomes your domicile, so the document is admitted to probate without complications. Powers of attorney are even more state-specific and should usually be redone.

Can I put my Florida homestead into a revocable living trust?

Yes. Florida permits a homestead to be held in a properly structured revocable living trust, and doing so helps avoid ancillary probate. However, the deed and trust language must be drafted carefully to preserve the homestead tax exemption and constitutional creditor protection, and to respect Florida’s restrictions on devising homestead when you have a surviving spouse or minor child.

How do I avoid probate in both New York and Florida?

The most reliable method is a fully funded revocable living trust that holds title to both your Long Island and Florida homes. At death, the successor trustee transfers the properties under the trust terms, avoiding both New York Surrogate’s Court and a separate Florida ancillary probate. Beneficiary designations and proper joint titling can supplement the trust for other assets.

What is Florida's homestead protection and who can inherit the home?

Florida homestead provides nearly unlimited protection from most creditors under the state constitution, plus property tax relief and the Save Our Homes assessment cap. But it also restricts inheritance: if you have a surviving spouse or minor child, you cannot freely leave the home to anyone else. An improper devise is void and the property passes by Florida’s statutory default rules instead.
