Estate Planning for Snowbirds and Dual-State Residents in Palm Beach, FL

Estate planning for snowbirds and dual-state residents is the work of organizing your domicile, ownership structures, and estate documents so that one state—ideally Florida—governs your estate, your tax exposure, and the administration of your assets after death. Done well, it lets a person who splits the year between, say, New York and Palm Beach claim Florida as their legal home, avoid double taxation and duplicate probate, and keep a closely held business from stalling when the owner is out of state or passes away. Done poorly, it invites two states to fight over your residency, your heirs to file probate in two courthouses, and your company to freeze at the worst possible moment.

I practice estate planning here in Palm Beach, and a large share of my clients live the dual-state life. They drive or fly south in October, return north in May, and assume their will from twenty years ago still covers them. It usually doesn’t. Below is the framework I walk business owners and retirees through when they want their estate to land in Florida and stay there.

Why Snowbirds Need a Different Estate Plan

Two states create two of everything. Two possible probate courts, two sets of income tax authorities, sometimes two estate or inheritance tax regimes. A snowbird who never formally cuts the cord with the northern state is, in the eyes of the law, often still a resident there—even if they spend seven months on the water in Jupiter.

The stakes are concrete. New York imposes a state estate tax with a so-called “cliff”: once a taxable estate exceeds the exemption by more than five percent, the entire estate—not just the overage—becomes taxable. Florida has no state estate tax and no state income tax at all. For a retiree with a $6 million estate, the difference between being taxed as a New Yorker and a Floridian can run into the hundreds of thousands of dollars. That gap is the whole reason the snowbird estate-planning conversation exists.

Where you are “domiciled” is the linchpin

Residency and domicile are not the same thing. You can be a resident of several states; you have exactly one domicile—the place you intend to return to and call home. Domicile drives which state taxes your estate, which state’s intestacy laws apply if your will fails, and which probate court has primary jurisdiction. Aggressive northern revenue departments audit former residents for years, and the burden often lands on the taxpayer’s estate to prove the move was real.

Establishing Florida Domicile the Right Way

Florida is welcoming, but the state you are leaving is not. Establishing domicile is less about a single magic document and more about a consistent body of evidence pointing in one direction. Here is the checklist I give clients, and I tell them to treat it as a project, not an afterthought.

• File a Declaration of Domicile in the county where you live. Florida Statutes Chapter 222 (specifically section 222.17) lets you record a sworn statement with the clerk of court declaring Florida your permanent home. In Palm Beach County you file it with the Clerk and Comptroller.
• Claim the Florida homestead exemption on your residence. Beyond the property-tax savings, homestead status is powerful evidence of intent and carries creditor protection under Article X, Section 4 of the Florida Constitution.
• Get a Florida driver’s license and register your vehicles here, then surrender the out-of-state license.
• Register to vote in Florida and actually vote here. Voting in your old state is one of the fastest ways to lose a residency audit.
• Move your financial and professional relationships south—primary bank, accountant, physicians, and the address on file with the IRS and Social Security.
• Spend the days. Many northern states use a 183-day rule. If you want to defeat a statutory-residency claim, you generally need to be physically outside the old state for more than half the year and keep a contemporaneous log.
• Update your estate documents to recite Florida domicile and to be valid under Florida law.

No single item on that list wins the case. The pattern does. An auditor looking at a person who declared Florida domicile, votes in Florida, sees a Florida doctor, and spends 210 days a year here has a hard time arguing the move wasn’t genuine.

Avoiding Ancillary Probate: The Two-Courthouse Problem

Suppose you successfully become a Floridian but still own the family cabin in the Adirondacks or a rental condo in Boston. When you die, your primary estate is administered in Florida, but real property titled in your individual name in another state usually requires its own proceeding there—called ancillary probate. Now your family is paying two sets of lawyers in two states and waiting on two courts.

Florida itself runs ancillary administration under Florida Statutes section 734.102 when a non-resident dies owning Florida property, and northern states do the reverse to your out-of-state real estate. The fix is almost always the same: get the title out of your sole individual name before death.

The revocable living trust as the master container

For dual-state owners, a properly funded revocable living trust is the workhorse. You retitle your Florida home, the out-of-state property, brokerage accounts, and business interests into the trust during life. Because the trust—not “you” personally—owns those assets at death, there is nothing to probate in either state. The successor trustee simply administers the trust under its terms. One administration, no courthouse in two states, and privacy because trusts are not filed in the public record the way wills are.

A trust is also the cleaner vehicle when the planning gets sophisticated. If you have a taxable estate, you’ll want to coordinate the revocable trust with credit-shelter or marital provisions. Clients who want to understand how trusts fit into a larger tax and asset-protection strategy can review this overview of , which lays out the major trust types in plain language.

The Documents Every Dual-State Resident Should Refresh

A move across state lines should trigger a full review, not a touch-up. The core set:

1. Last will and testament—re-executed to satisfy Florida’s formalities. Florida requires two witnesses and, to make the will “self-proving” so witnesses needn’t appear in court later, a notarized self-proving affidavit under Florida Statutes section 732.503. You can read more about the mechanics of a valid will on our wills page.
2. Revocable living trust—drafted under Florida law and, critically, funded. An unfunded trust is an empty box that solves nothing.
3. Durable power of attorney—Florida’s version, governed by Chapter 709, is more demanding than many states’. Powers must be specifically enumerated; a vague “all-purpose” POA from up north may be rejected by a Florida bank.
4. Designation of health care surrogate and living will under Florida Statutes Chapter 765, naming someone to make medical decisions and stating your wishes on life-prolonging treatment.
5. Updated beneficiary designations on retirement accounts and life insurance, which pass outside the will entirely and are a frequent source of accidental disinheritance after a move.

Out-of-state advance directives and powers of attorney are often theoretically valid in Florida, but “valid in theory” is cold comfort when a hospital or a teller hesitates during an emergency. Re-papering under Florida law removes the friction.

Succession Planning When You Own a Business

For the business owners who read this site, the dual-state question is sharper. If your company is organized in your old state but you now run it from a laptop in Palm Beach, where is it really managed? Which state taxes its income? And what happens to it if you’re incapacitated mid-season or pass away?

A few moves protect both the enterprise and your domicile claim:

• Decide where the entity should live. Some owners redomesticate the LLC or corporation to Florida or form a Florida holding company. Florida’s lack of state income tax and its strong LLC charging-order protections under Chapter 605 make it attractive—but redomestication has tax consequences and should be modeled before you pull the trigger.
• Put a buy-sell agreement in place. If there are co-owners, a buy-sell funded with life insurance fixes the price and the process when an owner dies, so the company doesn’t end up in business with a deceased partner’s heirs.
• Hold the business interest in your revocable trust so the ownership stake transfers without probate in any state.
• Name a successor manager and grant business-specific authority in your durable power of attorney, so the company keeps signing checks and contracts if you’re hospitalized.

Aging owners frequently combine this with elder-law planning—protecting the estate from long-term care costs while keeping the business intact for the next generation. For families navigating that overlap, this resource on is a useful primer on how Medicaid rules, asset protection, and succession interact.

Common and Costly Snowbird Mistakes

The same errors surface again and again. Watch for these:

• Declaring Florida domicile but keeping northern habits. Voting up north, keeping the old state as your “permanent address” on tax returns, or spending more than half the year there will unravel the whole plan in an audit.
• Owning out-of-state real estate in your individual name, guaranteeing ancillary probate.
• Signing a trust and never funding it. This is the single most common—and most expensive—mistake I see.
• Relying on an out-of-state durable power of attorney that Florida institutions won’t fully honor.
• Forgetting beneficiary designations and joint-titling, which override your will and trust no matter how carefully drafted.

If a probate has already begun—yours or a family member’s—because property was left in an individual name, you’ll want to understand the local process. We cover the basics on our Florida probate page.

Coordinating Counsel Across State Lines

A genuine dual-state plan benefits from lawyers licensed in each relevant state working together: Florida counsel for your domicile, homestead, and primary estate, and counsel in the other state for any real property or entity that stays behind. Firms with offices in multiple states make that coordination easier. Our colleagues handle the Florida side through their , and the documents are drafted to dovetail with whatever remains up north.

The goal is simple to state and a little harder to execute: one domicile, one administration, no surprises. With a Florida-anchored trust, refreshed Florida documents, retitled out-of-state property, and a disciplined approach to where you spend your days, the snowbird life becomes a tax and planning advantage instead of a liability your family inherits.

Frequently Asked Questions

How many days do I need to spend in Florida to be considered a resident?

Florida has no minimum-day requirement to claim domicile—it turns on intent and conduct. The day count matters mostly for the state you’re leaving. Many northern states use a 183-day statutory-residency rule, so to defeat their claim you generally want to be physically outside that state for more than half the year and keep a contemporaneous record of your whereabouts.

Will my New York will still work if I move to Florida?

It may be admissible, but it likely won’t be optimized. Florida has specific witnessing and self-proving requirements under section 732.503, and an out-of-state will can force your witnesses into court or trigger handwritten-will issues. Re-executing your will under Florida law avoids those problems and lets you recite your new domicile.

What is ancillary probate and how do I avoid it?

Ancillary probate is a second probate proceeding in a state where you own real estate but don’t reside. A Florida resident with a vacation home up north—or a non-resident with Florida property under section 734.102—triggers it. The cleanest way to avoid it is to title that out-of-state real estate in a revocable living trust so no probate is needed in either state.

Does Florida have an estate or inheritance tax?

No. Florida has no state estate tax, no inheritance tax, and no state income tax. The federal estate tax may still apply to very large estates, but for most snowbirds the savings come from shedding a high-tax home state—New York’s estate tax, with its cliff feature, being a common example.

I run a business from Florida but it’s incorporated up north. What should I do?

Start by modeling whether to redomesticate the entity to Florida or form a Florida holding company, since each has tax consequences. Then put a funded buy-sell agreement in place if you have partners, hold the ownership interest in your revocable trust, and grant business-specific authority in a Florida durable power of attorney so the company keeps running if you’re unavailable.
