Estate Planning for Snowbirds and Dual-State Residents: A Palm Beach Attorney’s Guide

Estate planning for snowbirds and dual-state residents means coordinating a single, legally consistent plan across two states so that your domicile is clear, your will is valid in both, and your assets pass without double taxation or duplicate probate. For Palm Beach business owners who summer up north and winter in Florida, the central question is not where you keep your stuff but which state claims you when you die. Get the domicile question wrong and two state tax authorities, two court systems, and two sets of intestacy rules can all stake a claim to your estate.

I have spent years untangling exactly these situations for clients who split their year between Florida and New York, New Jersey, Connecticut, Massachusetts, Ohio, and Illinois. The pattern repeats: a successful entrepreneur buys a place in Palm Beach, keeps the old house and the old accountant up north, and never formally decides which state is home. Their estate plan was drafted in one state, their property sits in another, and their family pays for the ambiguity. This guide walks through how to do it right.

Why dual-state residency complicates your estate plan

Every state has its own rules for three things that matter enormously at death: how it taxes you, how it probates your property, and how it interprets your will. When you maintain meaningful ties to two states, both can assert authority. The friction shows up in predictable places.

• Estate and inheritance tax. Florida has no state estate tax and no inheritance tax. Several northern states do. New York imposes an estate tax with a notorious “cliff” that can tax the entire estate, not just the amount over the exemption, if you exceed the threshold by more than 5%. Establishing Florida domicile is often the single most valuable estate planning move a high-net-worth snowbird can make.
• Probate. Real property is probated where it sits. Own a condo in Palm Beach and a lake house in New York, and your executor may face a primary probate in your domicile state plus an ancillary probate in the other. Two courts, two sets of fees, two timelines.
• Will validity and formalities. A will executed under one state’s signing rules is usually honored by another, but elective-share rights, spousal protections, and homestead rules differ sharply. Florida’s homestead protection, for example, is unusually strong and can override what your will says about your primary residence.

Domicile vs. residence: the distinction that controls everything

People use these words interchangeably. The law does not. You can have many residences but only one domicile — the single place you treat as your true, permanent home and intend to return to. Domicile is what determines which state taxes your worldwide income and intangible assets, and which state’s law governs the administration of your estate.

Domicile is a question of intent and fact. You cannot simply declare Florida home while keeping your whole life up north. Northern tax departments — New York’s in particular — audit former residents aggressively, looking at where you spend your time, where your “near and dear” possessions are kept, where your active business is run, and where your family and social life center. They will pull your credit card records, your phone location data, and your calendar.

How to establish Florida domicile that survives an audit

If your goal is to make Palm Beach your legal home, do it deliberately and document everything:

1. File a Florida Declaration of Domicile. Under Florida Statutes § 222.17, you may file a sworn declaration with the clerk of the circuit court in your county stating that Florida is your permanent home. This is a foundational document, not a magic bullet — but its absence is conspicuous.
2. Apply for Florida homestead exemption on your Palm Beach residence. Claiming homestead in two states is a red flag; you cannot.
3. Change your driver’s license, voter registration, and vehicle registration to Florida.
4. Spend more days in Florida than anywhere else, and keep a contemporaneous log. The 183-day rule is a floor, not a ceiling — a former domicile state can still come after you even if you clear it.
5. Move the center of your life. Change your primary physician, your accountant, your church or synagogue, your country club, and the address on your financial accounts. Update your estate plan to recite Florida domicile and execute it in Florida.

The estate plan itself is powerful evidence of intent. A will and revocable trust that recite your Florida domicile, drafted and signed in Florida by a Florida attorney, tell a tax auditor exactly where you considered home to be.

The double-probate trap and how to avoid it

Here is the scenario I see constantly. A client dies domiciled in Florida but still owns real estate in New York. Florida administers the estate, but because that out-of-state parcel cannot be transferred by a Florida court, the family must open a second, ancillary proceeding in New York. Florida itself recognizes this in reverse: under Florida Statutes § 734.102, a Florida ancillary administration is required when a nonresident dies owning Florida property. Either way, the survivors get two probates instead of one.

The cleanest fix is to keep real property out of probate altogether. The most reliable tool for a dual-state owner is a funded revocable living trust. Deed your Florida home and your out-of-state property into the trust during your lifetime, and at death the trustee transfers them privately — no court in either state. A well-built trust is the backbone of nearly every snowbird plan I draft. For an overview of how trusts function across jurisdictions, our affiliated explain the mechanics that apply equally to multi-state estates.

Other probate-avoidance tools that travel well across state lines:

• Enhanced life estate (Lady Bird) deeds for Florida real property, which pass the home automatically at death while preserving your control and homestead benefits during life.
• Beneficiary and transfer-on-death designations on financial and retirement accounts, reviewed so they actually match the rest of your plan.
• Proper titling of jointly held property, with attention to the differences between joint tenancy and tenancy by the entirety, which are not treated identically in every state.

Business succession for the dual-state owner

This is where Palm Beach business owners face their hardest decisions. If you run a company, the entity’s home state, your domicile, and the location of operations may all differ. Succession planning has to account for all three.

Where does the business “live”?

A New York operating business owned by a Florida-domiciled individual creates a genuine tension. New York may tax the business income sourced to the state regardless of where you live, while your ownership interest as intangible personal property is generally taxed by your domicile. Moving your domicile to Florida does not move your operating business — but it can dramatically change how your ownership stake is treated at death. This is one of the strongest arguments for formal Florida domicile among entrepreneurs.

The succession documents that should travel with you

• A buy-sell agreement funded with life insurance, so that on your death or incapacity your interest is purchased on pre-agreed terms instead of passing chaotically to heirs who may have no role in the business.
• An operating agreement or shareholder agreement that names successors, defines voting control during a transition, and anticipates the founder spending half the year out of state.
• A durable power of attorney valid in both states, so someone can sign for the business if you are incapacitated while away. Incapacity planning is frequently the weakest link for snowbirds, because a document drafted in one state may not be accepted at a bank or hospital in the other.
• Coordination with the trust, so business interests pass according to the succession plan rather than colliding with generic will provisions.

Because incapacity often arrives before death, elder-law planning belongs in every snowbird’s file. Our colleagues at the address the long-term-care and guardianship issues that hit dual-state families hardest, and the same principles inform how we structure powers of attorney and health-care directives in Florida.

Documents every snowbird should have valid in both states

At minimum, a dual-state plan should include:

• A last will and testament that recites your domicile and is properly executed under Florida law. (For a primer on Florida will requirements, see our guide to Florida wills.)
• A revocable living trust, fully funded with real property in both states.
• A durable power of attorney and a separate health-care surrogate / advance directive drafted to be honored in each state you spend time in.
• Updated beneficiary designations reconciled with the trust and will.
• A Declaration of Domicile if you are establishing Florida as home.

Florida is a friendly jurisdiction for this work — no state estate tax, robust homestead and creditor protections, and a well-developed probate code. That is precisely why so many entrepreneurs make Palm Beach their legal home. If your operating business or property is concentrated up north, you may want both a Florida plan and coordinated counsel there; the regularly works alongside northern attorneys to keep the two halves of a plan consistent.

Common mistakes I see in dual-state estates

• Claiming homestead in two states. It invites audit and is generally not permitted.
• A Florida move “on paper” only. Keeping your business, doctors, and social life up north while claiming Florida domicile is the fastest way to lose a residency audit.
• An unfunded trust. A trust that never received the deeds does nothing; the property still goes through probate.
• Stale powers of attorney. Banks and hospitals reject documents that are old, out-of-state, or non-conforming, often at the worst possible moment.
• Letting two attorneys work in silos. Your Florida and northern documents must reference and reinforce each other, not contradict each other.

When to bring in a Palm Beach estate planning attorney

If you own property in more than one state, run a business, or have an estate large enough to trigger a northern state’s estate tax, you should not be assembling this plan from online forms. The interaction between domicile rules, homestead law, business succession, and multi-state probate is exactly the kind of problem where a small drafting error costs the family six figures. A short consultation can tell you whether your current documents actually accomplish what you think they do.

Frequently Asked Questions

Do I have to give up my home up north to become a Florida resident for estate planning?

No. You can keep a residence in another state. Domicile, however, is the single place you treat as your true permanent home, and you can only have one. To make Florida your domicile you must shift the center of your life here — days spent, driver’s license, voter registration, homestead exemption, and a filed Declaration of Domicile under Florida Statutes 222.17 — while not claiming homestead or domicile elsewhere.

Will my out-of-state will be valid in Florida?

Generally a will validly executed under another state’s law is honored in Florida, but that is not the whole story. Florida’s homestead, elective-share, and probate rules can override or complicate provisions drafted elsewhere. If Florida is now your home, the safest course is to execute a new will and trust under Florida law that recites your Florida domicile.

How do I avoid probate in two different states?

Use a fully funded revocable living trust and deed both your Florida property and your out-of-state real estate into it during your lifetime. Because the trust owns the property, no court administers it at death, which eliminates both the primary probate and the ancillary probate that out-of-state real estate would otherwise require.

How does dual-state residency affect my business succession plan?

Your operating business stays in its home state for income-tax purposes, but your ownership interest is generally treated as intangible property taxed by your domicile. Establishing Florida domicile can change how that interest is taxed at death. A funded buy-sell agreement, an updated operating or shareholder agreement, and a durable power of attorney valid in both states keep the business transition orderly regardless of where you are when you die or become incapacitated.

Does Florida have an estate or inheritance tax?

No. Florida imposes neither a state estate tax nor an inheritance tax. This is a major reason high-net-worth snowbirds formalize Florida domicile, since several northern states — New York among them — do tax estates, sometimes with a cliff that taxes the entire estate once you exceed the exemption by more than a small margin.
