Estate planning for snowbirds and dual-state residents means building a will, trust, and powers of attorney that account for owning a home and spending time in two states, while clearly establishing one state as your legal domicile. For people who winter in Florida and summer up north, the central questions are which state’s law governs your estate, where your assets will pass through probate, and how to avoid being taxed or probated twice. Getting domicile right is the single most important decision, and Florida’s homestead and tax rules usually make it the favorable choice.
If you split your year between, say, a condo in Boca Raton and a house in New Jersey or New York, you are not just managing two thermostats. You are sitting on top of two sets of laws that both think they have a claim to you. Two probate courts, two sets of intestacy rules, and potentially two state estate or inheritance tax regimes. A plan that was perfectly fine when you lived in one place full-time can quietly fall apart the moment you start living in two.
This guide is written for first-time planners and younger families who are just starting to spend serious time in Florida, as well as for retirees formalizing the snowbird life. The good news: with a few deliberate steps, the dual-state situation becomes a strength rather than a liability.
What “domicile” actually means (and why it controls everything)
Residence and domicile are not the same thing. You can be a resident of two states at once. You can only have one domicile. Domicile is your true, fixed, permanent home, the place you intend to return to, and it is the state whose law generally governs your will, your estate taxes, and the administration of your estate.
Florida courts and the IRS look at the totality of your conduct, not at any single document. There is no magic number of days, though the often-cited 183-day threshold matters a great deal for income tax residency in states like New York. What examiners weigh includes:
- Where you are registered to vote, and where you actually vote
- Your driver’s license and vehicle registration
- The address on your federal tax returns
- Where you file for the Florida homestead exemption
- Where your physicians, dentist, and “things near and dear” are located
- Where you spend the majority of your days, supported by records
The reason this matters for estate planning is blunt: if you die while a northern state still considers you domiciled there, that state can subject your entire estate to its estate or inheritance tax, even on assets sitting in Florida. Florida has no state estate tax and no income tax, so a clean domicile shift can be one of the most valuable moves a snowbird ever makes. But “clean” is the operative word. Half-measures invite an audit of your estate after you are gone, when you are no longer around to explain yourself.
The Declaration of Domicile under Florida law
Florida gives you a specific tool to memorialize your intent. Under Florida Statutes section 222.17, a person who resides in Florida and intends to maintain Florida as a permanent home may file a sworn Declaration of Domicile with the clerk of the circuit court in the county where they live. It is inexpensive, and while it is not by itself conclusive, it is strong contemporaneous evidence of intent. Pair it with the practical steps above, and you build a record that is hard to attack.
Florida homestead: powerful protection, surprising restrictions
Florida’s homestead is famous, and rightly so, but snowbirds often misunderstand it. It does three different things, governed by different parts of the law, and they are easy to conflate.
First, the creditor protection. Under Article X, Section 4 of the Florida Constitution, your homestead is shielded from most creditors, with essentially no dollar cap on value (only acreage limits: up to half an acre inside a municipality, up to 160 acres outside). For families worried about lawsuits or debt, this is a genuine reason to put down roots in Florida.
Second, the tax exemption that reduces your assessed value and locks in the Save Our Homes assessment cap. You claim this with the county property appraiser, and claiming it is one of the strongest signals of Florida domicile.
Third, and this is where plans go sideways, the homestead inheritance restrictions in Article X, Section 4(c). If you are married or have minor children, Florida sharply limits how you can leave your homestead. You generally cannot disinherit a spouse from the homestead, and you cannot devise it at all if you have a minor child. A snowbird who assumes “I’ll just leave the condo to my kids in my will” can be shocked to learn the will is overridden by the constitution. This is one of the most common traps we see, and it is why a Florida-specific review matters even if you already have a perfectly good out-of-state will.
Two homes, two probates: the cost of doing nothing
Here is the scenario that motivates most of this planning. You own a home in Florida and a home up north, both titled in your individual name. You pass away. Your “home state” probate handles the northern house and your financial accounts. But the Florida real estate cannot be transferred by an out-of-state court, so your family also has to open an ancillary probate in Florida under Chapter 734 of the Florida Statutes.
That means two court proceedings, two sets of attorneys, two timelines, and two sets of fees, often running many months in parallel. Florida formal administration alone commonly takes six months to a year. Doubling the process doubles the friction at exactly the moment your family is least equipped to handle it.
The standard fix is a properly funded revocable living trust. You transfer the Florida home (and ideally the northern home and major accounts) into the trust during your life. At death, the successor trustee distributes the assets according to your instructions, no probate in either state. A trust is also private, where probate is a public record, and it keeps your affairs out of two courthouses. For an overview of how these instruments work, this is a useful primer, and the same principles apply across state lines.
When a will alone is enough, and when it isn’t
Younger families with one modest property and uncomplicated assets may reasonably start with a well-drafted will plus beneficiary designations and, where appropriate, a Florida enhanced life estate deed (the “Lady Bird deed”) to pass real estate outside probate. As your footprint grows to two homes in two states, the math tilts decisively toward a trust. The right answer depends on your facts; you can read more about the basics on our wills page and about Florida court procedure on our Florida probate page.
Wills and documents that work across state lines
A common worry: “I made my will in New York, is it valid in Florida?” Generally, yes. Florida recognizes a will that was validly executed under the law of the state where it was signed. So a will properly executed up north will usually be honored here.
But “valid” is not the same as “optimal.” Two issues recur:
- Out-of-state executors. Florida law restricts who may serve as a personal representative. A nonresident generally cannot serve unless they are a close relative (spouse, child, sibling, parent, and certain others) or related by lineal or adopted kinship. A snowbird who names a longtime friend or neighbor up north as executor may find that person legally disqualified to serve in Florida.
- Self-proving affidavits. Florida wants a self-proved will under section 732.503 so the court need not track down witnesses. A will from another state may use different attestation language, which can slow probate.
Beyond the will, your durable power of attorney and health care directives deserve special attention. Florida’s durable power of attorney statute (Chapter 709) is unusually strict; it does away with “springing” powers and requires specific formalities and exact authority for certain acts. A power of attorney drafted under another state’s looser rules may be honored, but banks and title companies in Florida frequently balk at unfamiliar documents. The practical move is to execute a fresh Florida-compliant durable power of attorney, health care surrogate designation, and living will once you spend real time here. Keep your northern documents too; you want valid instruments in both places.
Special situations dual-state families should plan around
A few circumstances raise the stakes and deserve a tailored approach rather than a template.
A child or beneficiary with a disability. Leaving assets outright to a loved one who receives needs-based public benefits can disqualify them. The solution is a third-party special needs trust, structured so the inheritance supplements rather than replaces government support. Because many snowbird families keep ties to the Northeast, coordination matters; if your beneficiary lives or receives services in New York, an attorney who handles a can align that planning with your Florida documents so nothing falls through the cracks between states.
Blended families and second marriages. Florida’s elective share (Chapter 732) gives a surviving spouse a statutory percentage of the estate, and the homestead rules above can override your wishes. Couples who married later in life, or who each bring children from prior relationships, need their plan stress-tested against these rules so the surviving spouse and the children are both protected as intended.
Real estate in three or more states. A vacation property in the mountains plus the two primary homes can mean three ancillary probates. Trust funding, or in some cases an LLC for the investment property, becomes essential.
Coordinating Florida and out-of-state counsel
Dual-state planning is genuinely a two-jurisdiction exercise. You want your Florida documents and your northern documents to speak to each other, not contradict each other. In practice that often means one firm quarterbacking the Florida side, the homestead, the Declaration of Domicile, the Florida-compliant powers of attorney, while coordinating with counsel up north on anything that must remain governed by the other state’s law. Our firm regularly handles the Florida piece for families whose lives straddle two states, and works alongside out-of-state advisors so the whole plan hangs together.
A practical checklist before you split your year
If you are about to formalize the snowbird life, work through this list with an attorney:
- Decide your domicile deliberately, then make your conduct consistent with it (voter registration, license, tax returns, doctors)
- File a Florida Declaration of Domicile and claim the homestead exemption if Florida is your choice
- Confirm your executor and trustee can legally serve in Florida
- Execute Florida-compliant durable power of attorney, health care surrogate, and living will
- Consider a revocable trust funded with both homes to avoid double probate
- Review homestead devise restrictions if you are married or have minor children
- Address special needs, blended-family, and multi-state property issues directly
None of this is exotic. It is just specific, and the specifics are where dual-state families most often go wrong. A short planning session now spares your family two courthouses later.

Frequently Asked Questions
Do I have to change my domicile to Florida to get the tax benefits?
Yes. Florida’s absence of a state income tax and estate tax only protects you if Florida is your legal domicile, not merely a place you visit. To establish it, your conduct must consistently point to Florida: register to vote and get your driver’s license here, file your federal return from your Florida address, claim the homestead exemption, and ideally file a Declaration of Domicile under Florida Statutes section 222.17. If a northern state still considers you domiciled there at death, it can tax your entire estate.
Is my out-of-state will valid in Florida?
Usually, yes. Florida generally honors a will that was validly executed under the laws of the state where you signed it. However, valid is not the same as optimal. Florida restricts who can serve as your personal representative (nonresidents must typically be close relatives), and Florida prefers a self-proving affidavit under section 732.503. Many snowbirds update to a Florida-compliant will and powers of attorney once they spend significant time in the state.
Will my family have to go through probate in both states?
If you own real estate in your individual name in two states, yes, generally. Your home state handles the main estate, and Florida requires a separate ancillary probate under Chapter 734 to transfer Florida property. The most reliable way to avoid this is a properly funded revocable living trust holding both homes, which lets a successor trustee distribute the assets without probate in either state.
Can I just leave my Florida home to my children in my will?
Not always. Florida’s constitutional homestead rules (Article X, Section 4) restrict how you can devise your homestead if you are married or have a minor child. You generally cannot disinherit a spouse from the homestead, and you cannot devise it at all if you have a minor child. A will that ignores these rules can be partially overridden by the constitution, so the homestead needs to be planned around specifically.
What estate planning documents should every snowbird have in Florida?
At a minimum: a will or revocable trust coordinated across both states, a Florida-compliant durable power of attorney under Chapter 709, a Florida health care surrogate designation, and a living will. Florida’s power of attorney rules are strict and eliminate springing powers, so an out-of-state document may be rejected by Florida banks or title companies. Keeping valid documents in both states is the safest approach.
