Estate planning for snowbirds and dual-state residents means building a coordinated plan that reconciles the laws of two states, clearly fixes your legal domicile in one of them, and titles your property so that no court outside your home state has to be involved when you die. For most clients who split the year between a northern state and Florida, the goal is to make Florida the legal home and to hold out-of-state real estate in a way that sidesteps a second probate. Done correctly, the result is lower taxes, simpler administration, and far less for your family to untangle later.
I have spent years walking Miami clients through exactly this problem, and the pattern repeats: someone retires, buys a place in South Florida, keeps the house up north, and assumes the old will still “works.” It usually does work — just not the way they intended, and often in the most expensive state possible. Below is how I think about it.
Why dual-state living complicates an estate plan
Two states means two sets of rules, and they rarely agree. Probate procedure, spousal rights, creditor protection, estate and inheritance taxes, and even how a will must be witnessed all vary. A document that is perfectly valid in New York or New Jersey may still trigger a separate court proceeding in Florida — and vice versa — if you own real property in both places.
The three pressure points I watch for are these:
- Domicile. You can have many residences but only one domicile. Domicile drives which state taxes your income and estate, which state’s law governs your will, and which courts have primary jurisdiction. Two states both claiming you is a real and costly fight.
- Ancillary probate. Real estate is governed by the law of the state where it sits. Own a condo in Florida and a lake house in Michigan, and your family may face a main probate in one state plus a second “ancillary” probate in the other.
- State death taxes. Florida has no state estate or inheritance tax. Several northern states do, and some reach assets even after you move if domicile is sloppy. Getting domicile right is, for many families, the single most valuable thing the plan accomplishes.
Establishing Florida domicile the right way
For snowbirds, the most consequential decision is which state to call home. Florida is frequently the answer because it has no income tax, no estate tax, and unusually strong homestead and creditor protections. But you do not become a Floridian simply by buying a condo and spending January here. Domicile is a question of intent backed by conduct, and a former home state — especially a high-tax one — may audit aggressively to keep you on its rolls.
Documenting intent under Florida law
Florida law gives you tools to make your intent unmistakable. Under Florida Statutes § 222.17, a person who lives in Florida but maintains a home in another state may file a sworn Declaration of Domicile with the clerk of the circuit court, stating that the Florida residence is their “predominant and principal home” which they intend to continue permanently. It is a recorded public document and one of the cleanest pieces of evidence you can create.
The homestead tax exemption reinforces this. Under Florida Statutes § 196.031, an owner who in good faith makes Florida property their permanent residence may claim a homestead exemption, and § 196.012(17) defines that permanent residence as the “true, fixed, and permanent home… to which, whenever absent, he or she has the intention of returning.” A person may have only one such residence. Claiming Florida homestead while also claiming a residency-based exemption up north is the kind of contradiction that hands an auditor an easy case.
Beyond the formal filings, I tell clients to make their whole life point at Florida:
- File the Declaration of Domicile and apply for the Florida homestead exemption on your South Florida home.
- Obtain a Florida driver’s license and register your vehicles here; register to vote in your Florida county and actually vote.
- Move primary banking, brokerage, and your physician, dentist, and CPA relationships to Florida where practical.
- Update your will, trust, powers of attorney, and health care documents to recite Florida domicile and comply with Florida execution formalities.
- Keep a simple record — a calendar or app — of where you spend each day, because day-count tests (often the 183-day rule) are decided on evidence, not memory.
No single item controls. Auditors look at the totality. The clients who win are the ones whose paperwork and behavior tell one consistent story.
Avoiding a second probate on out-of-state property
Even with domicile settled, real estate in another state remains a trap. If you die owning that northern house in your individual name, your executor will likely open an ancillary probate there in addition to administering your Florida estate — two courts, two sets of fees, two timelines, and two opportunities for delay.
The cleanest solution is usually a revocable living trust. You transfer the deeds to your out-of-state and Florida real property into the trust during your lifetime. Because the trust — not you personally — owns the real estate at death, there is no asset standing in your individual name for any probate court to administer. The trustee simply follows the trust and distributes or sells the property privately. A well-drafted trust also handles incapacity, keeps your affairs out of the public record, and can layer in protections for a surviving spouse or for beneficiaries who need oversight. For clients weighing whether a trust fits their situation, this overview of is a useful starting point.
Trusts are not the only tool. Depending on the state and the property, alternatives include a transfer-on-death or “lady bird” (enhanced life estate) deed, or careful joint titling — though joint ownership carries its own creditor and tax risks and should never be used reflexively. The right instrument depends on which states are in play and what the property is worth. You can read more on our Florida probate and wills pages, but the choice should be made with counsel, not from a template.
Planning for incapacity across state lines
Estate planning is not only about death. If you are hospitalized in one state while your agent and documents live in another, the practical question is whether local doctors and banks will honor what you signed.
Florida has specific formalities for durable powers of attorney and for advance directives, and they differ from those up north. A power of attorney that is “durable” and immediately effective under Florida law may be treated differently elsewhere. I generally recommend that dual-state clients execute a fresh set of incapacity documents that comply with Florida formalities once domicile shifts here, and keep them coordinated with — not contradicting — any documents that remain useful in the other state. A Florida health care surrogate designation, living will, and HIPAA release should travel with you both ways.
Special-needs and beneficiary considerations
For families supporting a disabled child or relative, a move multiplies the complexity, because public-benefit programs are administered state by state. A trust that protects eligibility for needs-based benefits must be drafted with the governing state’s program rules in mind. If beneficiaries remain up north while you relocate, that planning may belong there even though your own estate plan now sits in Florida. Our colleagues handle this regularly; see their guidance on a for how these arrangements preserve benefits while still providing for a loved one. The point is coordination: the trust for the beneficiary and your own domicile plan have to be built to work together.
Special concerns for high-net-worth dual-state families
The stakes rise sharply with wealth. A high-net-worth family that splits time between New York and Miami may be exposed to a state estate tax measured in the hundreds of thousands of dollars if domicile is not cleanly Florida at death. The federal estate tax exemption is generous but not permanent, and state-level taxes operate independently of it.
For these clients I look at a few additional layers:
- Asset protection. Florida’s homestead protection and its treatment of certain accounts and entities can shield wealth from creditors in ways other states do not match — another reason to anchor domicile here deliberately.
- Business and real-estate holdings. Investment property is often best held in LLCs whose interests, rather than the underlying deeds, pass through the trust — simplifying multi-state administration.
- Irrevocable trusts and gifting. Larger estates may use irrevocable structures to remove appreciating assets from the taxable estate, but these are not one-size-fits-all and demand careful drafting.
Because so many South Florida families keep ties to the Northeast, we coordinate Florida-side planning with counsel where the other property and beneficiaries sit. If your second home or business is in the Northeast, the team at can work alongside out-of-state attorneys so both halves of your plan agree.
A practical sequence for getting it done
If you are a snowbird who has not revisited your plan since relocating, the order of operations I recommend is straightforward: settle domicile first, then re-title real property, then refresh your core documents, then address taxes and any specialized trusts. Trying to do it piecemeal — a homestead exemption here, a new will there — is how contradictions creep in. The whole value of dual-state planning is that everything points the same direction.
Every family’s mix of states, assets, and beneficiaries is different, and the statutes summarized here are general — not a substitute for advice on your specific situation.

Frequently Asked Questions
Do I have to give up my northern home to become a Florida resident for estate planning?
No. You can keep a home in another state and still be domiciled in Florida. Florida Statutes § 222.17 specifically lets a person who maintains an out-of-state residence file a Declaration of Domicile stating that the Florida home is their predominant and principal home. What matters is that your conduct, filings, and documents consistently treat Florida as your one permanent home.
Will my out-of-state will have to go through probate in Florida?
A will valid where you signed it is generally recognized in Florida, but owning real estate in two states often forces two separate probates: a main proceeding in your home state and an ancillary one wherever the other property sits. The common fix is to place real property into a revocable living trust during your lifetime so no asset stands in your individual name at death, eliminating the need for ancillary probate.
How do I prove Florida is my domicile if my old state audits me?
There is no single magic document. Auditors weigh the totality of your conduct, so you build a consistent record: file a Declaration of Domicile and claim Florida homestead under § 196.031, get a Florida driver’s license, register and actually vote here, move primary banking and key professional relationships to Florida, update your estate documents to recite Florida domicile, and keep a day-by-day record of where you spend your time.
Does Florida have an estate or inheritance tax?
Florida imposes no state estate or inheritance tax, which is a major reason snowbirds work to establish Florida domicile. However, the federal estate tax still applies to large estates, and some northern states levy their own death taxes. If your domicile is not cleanly Florida at death, a former home state may try to tax your estate, so getting domicile right is often the most valuable part of the plan.
What documents should I redo after moving to Florida?
At minimum, refresh your will or trust, durable power of attorney, health care surrogate designation, living will, and HIPAA release so they comply with Florida formalities and recite Florida domicile. Coordinate these with any documents that remain useful in your other state so they reinforce rather than contradict each other, and re-title real property as part of the same process.
