Estate planning for snowbirds and dual-state residents means building a plan that works across the two (or more) states where you live, own property, and pay taxes — while choosing one of them as your legal home, or domicile. For most people who split the year between a northern state and Florida, the goal is to establish Florida as the domicile to capture its tax and creditor advantages, then coordinate the will, trust, and property titling in both states so the estate doesn’t get probated twice. Done right, it saves heirs money, time, and a second courthouse.
I’ve sat across the table from a lot of retirees who assumed that buying a condo in Miami-Dade and spending six months a year here automatically made them Floridians. It doesn’t. And the gap between what people assume and what the law actually requires is exactly where families get hurt — usually after the snowbird has passed and it’s too late to fix anything.
What “Domicile” Means and Why It Drives Everything
Residence and domicile are not the same thing. You can have homes in several states, but you have only one domicile: the state you treat as your true, fixed, permanent home and the place you intend to return to. Your domicile decides which state’s law governs your will, which state taxes your income and your estate, and — frequently — where the bigger fight happens after you’re gone.
This matters enormously for snowbirds because the high-tax states do not let go easily. New York, New Jersey, Connecticut, and others have aggressive residency audit programs. If you claim Florida but keep your “life” up north, the old state can argue you never actually left and pull your entire estate back into its tax net. The burden of proving the change often falls on you — or, after death, on your executor.
How Florida domicile is actually established
There is no single magic act. Florida domicile is proven by a pattern of behavior that shows intent plus physical presence. The strongest steps include:
- Filing a Declaration of Domicile with the clerk of court in your Florida county (authorized under Florida Statutes §222.17).
- Applying for the Florida homestead exemption on your residence and surrendering any homestead or residency-based benefit in the other state.
- Getting a Florida driver’s license and registering your vehicles here.
- Registering to vote in Florida — and actually voting here.
- Changing the address on tax returns, bank and brokerage accounts, passports, and insurance to your Florida home.
- Spending more than half the year in Florida and keeping records (calendars, travel receipts, credit-card geography) that prove it.
The day-count rule is the one people most often underestimate. High-tax states commonly use a 183-day “statutory residency” test: if you maintain a home up north and are physically present there for more than 183 days, that state may tax you as a resident regardless of where your driver’s license says you live. A day with any part of it spent in the state usually counts as a full day. Keep a contemporaneous log.
The Florida Advantages Snowbirds Are Chasing
Florida is a destination for a reason. There is no state income tax and no state estate or inheritance tax. For a retiree drawing down retirement accounts and pensions, that alone can be worth tens of thousands of dollars a year compared with a northern state.
The other crown jewel is the homestead. Article X, Section 4 of the Florida Constitution gives a permanent Florida residence three distinct protections: an unlimited exemption from most creditors’ forced sale (your homestead generally cannot be taken to satisfy a money judgment), a property-tax exemption with the “Save Our Homes” 3% annual assessment cap, and restrictions on how the homestead can be left by will.
That third feature is a double-edged sword, and it surprises people. If you are survived by a spouse or a minor child, you cannot freely devise your homestead to anyone else. The constitution restricts it. So the snowbird who plans to leave the Miami condo to one child while a minor child or a spouse survives may find the will partly overridden by operation of law. This is precisely the kind of detail a Florida-specific plan has to account for.
The Double-Probate Trap
Here is the problem that brings dual-state families to my office more than any other. When you die owning real estate in two states, your estate typically must be probated in each state where you hold real property. Your domicile state handles the main (“domiciliary”) probate; the other state requires a separate ancillary probate for the property located there.
So the New York snowbird who keeps the family lake house up north and the condo in Brickell can leave heirs with a Florida probate and a New York probate — two courts, two sets of fees, two timelines, and two opportunities for things to go sideways. Ancillary administration in Florida is governed by Florida Statutes §734.102, and while it’s a defined process, it is still a second proceeding with its own cost.
How a revocable living trust solves it
The cleanest fix is a properly funded revocable living trust. Assets titled in the name of the trust are not subject to probate at all — in any state. If both the Florida home and the out-of-state property are deeded into the trust during your lifetime, your successor trustee can transfer or sell them after death without ever opening a probate case in either jurisdiction.
The phrase that matters is “properly funded.” A trust document sitting in a drawer does nothing; the deeds and account titles actually have to be changed to put the property into the trust. I see unfunded trusts constantly, and they fail at exactly the moment they’re needed. If you’d like to understand how trusts function as the backbone of a multi-state plan, is a useful starting point, and our Florida team handles the local funding and deed work through our .
Coordinating Documents Across State Lines
Even with a trust, you still need a coordinated set of core documents. A few cross-border issues deserve special attention:
- Pour-over will: a Florida will that catches any asset you forgot to retitle and sends it into your trust at death.
- Durable power of attorney: Florida’s POA statute (Chapter 709) has specific execution and “superpower” provisions. A power of attorney drafted for New York may be honored grudgingly — or rejected — by a Florida bank. Many dual-state clients execute documents valid in both states.
- Health care directives: Florida recognizes a designation of health care surrogate and a living will under Chapter 765. If you split time, keep directives that hospitals in both states will accept and make sure family can produce them quickly.
- Spousal elective share: if Florida is your domicile, your surviving spouse is entitled to an elective share equal to 30% of the elective estate under Florida Statutes §732.2065 — and that share reaches certain non-probate assets. Disinheriting a spouse is far harder than people think, so plans built in another state should be re-checked against Florida law.
Special situations: beneficiaries with disabilities
Dual-state families often include a child or grandchild who receives needs-based government benefits. Leaving money to that person outright — in either state — can disqualify them from Medicaid and SSI. The tool here is a special needs trust, which holds the inheritance for the beneficiary’s benefit without counting as their own resource. Because rules differ by state, the trust must be drafted to satisfy the law where the beneficiary lives. Our New York office maintains a detailed resource on the , and we coordinate those plans with Florida administration when the family is split between the two states.
A Practical Sequence for the Snowbird
When a new dual-state client asks where to begin, I give them an order of operations. It keeps the tax move and the estate plan from working against each other.
- Decide on domicile deliberately. Run the numbers on income and estate tax in both states before you commit.
- Establish Florida domicile with documentation. File the Declaration of Domicile, claim homestead, switch your license and voter registration, and keep a day log.
- Sever residency ties up north. Give up the other state’s homestead/residency benefits — keeping them is the single biggest red flag in a residency audit.
- Build or update the trust under Florida law, then fund it with the Florida home, the out-of-state property, and your major accounts.
- Re-execute powers of attorney and health directives so they work in both states.
- Review beneficiary designations. Retirement accounts and life insurance pass by designation, not by will — make sure they match the plan.
None of this is exotic, but the sequence and the local detail are where plans succeed or fail. A will copied from a northern template, or a trust that was never funded, can undo years of careful tax planning in a single probate filing.
If you spend part of the year in South Florida and the rest up north, the smartest move is to have one attorney look at the whole picture — domicile, homestead, both properties, and your existing documents — rather than treating the Florida condo as an afterthought. You can review our local Florida probate and wills and trusts resources, and when you’re ready to map your own situation, reach out to our Miami office to start the conversation.
Frequently Asked Questions
Do I automatically become a Florida resident if I buy a home in Miami and stay for the winter?
No. Owning a Florida home and spending the season here does not by itself change your legal domicile. You must show intent and presence through steps like filing a Declaration of Domicile, claiming the Florida homestead exemption, getting a Florida driver’s license, registering to vote here, and spending more than half the year in Florida — while giving up residency-based benefits in your other state.
Will my estate have to go through probate in two states?
If you die owning real estate in both your domicile state and another state, your estate generally must be probated in each — a main probate where you’re domiciled and a separate ancillary probate (Florida Statutes §734.102) where the other property sits. A properly funded revocable living trust avoids this by removing the real estate from probate entirely in both states.
Does my New York will still work if I move my domicile to Florida?
It may be valid, but it should be reviewed. Florida has its own rules on homestead devise, the 30% spousal elective share under §732.2065, and power-of-attorney execution. A will or power of attorney drafted under another state’s law can produce unintended results or be questioned by Florida institutions, so dual-state clients usually update their documents to satisfy Florida law.
What is the main tax reason snowbirds switch domicile to Florida?
Florida has no state income tax and no state estate or inheritance tax, unlike many northern states. For retirees drawing down pensions and retirement accounts, and for larger estates, establishing genuine Florida domicile can produce substantial savings — provided you also sever ties to the higher-tax state to withstand a residency audit.
How do I protect an inheritance for a family member who receives government benefits?
Leave the inheritance through a special needs trust rather than outright. An outright gift can disqualify a beneficiary from needs-based programs like Medicaid and SSI, while a properly drafted special needs trust holds the funds for their benefit without counting as their personal resource. The trust must comply with the law of the state where the beneficiary lives.
