Estate planning for snowbirds and dual-state residents is the process of structuring your will, trusts, and beneficiary designations so a single, coherent plan governs property located in two or more states—while choosing one state as your legal domicile to control which laws and taxes apply at death. For Floridians who winter in the Sunshine State and summer up north, the central task is establishing Florida domicile, avoiding probate in multiple states, and protecting high-value assets across jurisdictions.
I have spent years guiding affluent clients through exactly this puzzle. The recurring mistake is not a lack of documents—most of these clients have plenty—but a collection of plans that quietly contradict each other across state lines. A New York revocable trust funded with a Florida condo. A homestead the IRS and two tax departments both want to claim. A power of attorney that one bank honors and another rejects. The fix is rarely complicated. It just has to be deliberate.
What “domicile” actually means for snowbirds
Residence and domicile are not the same thing, and the difference drives nearly everything else. You can have several residences. You have exactly one domicile: the place you intend to return to and treat as your permanent home. Domicile decides which state’s law governs your will, where your estate is primarily administered, and—critically for high-net-worth families—which state, if any, taxes your estate and your income.
Florida is the obvious target. It has no state income tax and no state estate or inheritance tax, and its homestead protections are among the strongest in the country. But your former state does not let you walk away quietly. New York, Connecticut, New Jersey, Massachusetts, and Illinois are aggressive about residency audits, and they will argue you never truly left. They look at where you spend your time, where your “near and dear” possessions live, where you vote and bank, and the everyday facts of your life.
Building a defensible Florida domicile
If you intend to claim Florida, claim it convincingly. The single most important factor in most residency audits is the day count: spend more than 183 days a year in your former state and you risk being taxed as a statutory resident there regardless of intent. Beyond the calendar, the supporting record matters.
- File a Florida Declaration of Domicile under Florida Statutes § 222.17 with the clerk of court in your county. It is a sworn statement that Florida is your permanent home.
- Claim the Florida homestead exemption on your residence and surrender any comparable exemption (like New York’s STAR) up north.
- Move the everyday anchors: driver’s license, voter registration, vehicle registration, and primary bank and brokerage relationships.
- Update your estate documents to recite Florida domicile and to be executed under Florida law with Florida witnesses and notarization.
- Relocate the irreplaceable: family photos, heirlooms, pets, and the art on your walls. Auditors take “where your heart is” literally.
- Engage Florida professionals: a Florida physician, dentist, accountant, and attorney all reinforce the narrative.
None of these alone is decisive. Together they form the pattern an auditor is trained to look for.
Why dual-state property triggers ancillary probate
Here is the trap that catches even sophisticated families. Florida real estate owned in your individual name at death must pass through Florida probate, and out-of-state real estate owned in your name passes through probate in that state too. The result is ancillary probate—a second, parallel court proceeding in the second state, governed by Florida Statutes § 734.102 when Florida is the ancillary jurisdiction. It is slower, it is public, and it doubles the legal expense.
For a snowbird who owns a home in Palm Beach and a lake house in Michigan, dying with both titled individually can mean two probate cases, two sets of court fees, and two timelines that must each resolve before heirs receive clear title. The good news: this is almost entirely avoidable.
Tools that keep dual-state property out of probate
- A funded revocable living trust. Retitle the Florida home and the out-of-state property into one trust, and a single document governs both. No probate in either state, and your plan stays private. For most of my dual-state clients this is the workhorse solution. If you want to understand the mechanics first, our wills and probate primer walks through the basics, and you can read more about how a properly funded plan avoids court entirely below.
- An enhanced life estate (“Lady Bird”) deed. Florida recognizes this deed, which lets you keep full control during life and pass the property automatically at death without probate or losing the homestead exemption or step-up in basis.
- Joint ownership with rights of survivorship. Useful for spouses, but it is a blunt instrument—it does nothing for the second death and can expose the asset to a co-owner’s creditors.
A revocable trust does not, by itself, save estate taxes or shield assets from your own creditors. It solves the administration and privacy problem brilliantly, and for snowbirds the multi-state administration problem is the real headache. To go deeper on the differences between trust types and what each one accomplishes, Morgan Legal’s overview of trust planning options is a useful reference.
Florida homestead: a shield and a trap
Florida’s homestead is a remarkable asset-protection tool. Under Article X, § 4 of the Florida Constitution, your homestead is shielded from most creditors without dollar limit—one reason high-net-worth individuals relocate here in the first place. But the same constitution imposes strict devise restrictions. If you are survived by a spouse or minor child, you cannot freely leave the homestead to whomever you please. Get this wrong and the property passes by operation of law, overriding your will.
For blended families—common among clients on a second marriage with adult children from a first—this is where plans implode. A homestead left outright to a new spouse can disinherit your children entirely, or trigger a statutory life-estate/remainder split nobody intended. These problems have clean solutions (a properly drafted trust, a spousal waiver, or careful titling), but only if addressed before death rather than litigated after.
Coordinating documents across two states
Your estate plan is a system, not a folder of paper. When you live in two states, several documents need to work in both.
Powers of attorney and health care directives
Florida’s durable power of attorney statute (Chapter 709) is unusually demanding—it abolished “springing” powers and requires specific authority to be initialed for certain hot powers like making gifts. A power of attorney drafted for New York may be technically valid yet practically useless when a Florida bank’s legal department reviews it. I generally recommend executing a Florida-compliant durable power of attorney and a Florida health care surrogate designation, and keeping parallel documents valid in your northern state so your agent is never stuck at the wrong border.
Wills, trusts, and beneficiary designations
Your will should be executed under the law of your domicile and recite that domicile clearly. Beneficiary designations on retirement accounts, life insurance, and annuities pass outside both your will and any trust—so they must be reviewed and reconciled with the rest of the plan, or they will quietly contradict it. I have seen a meticulously drafted trust undone by a decades-old 401(k) form naming an ex-spouse.
Asset protection for high-net-worth dual-state families
Choosing Florida is itself an asset-protection decision. Beyond the unlimited homestead exemption, Florida protects the cash surrender value of life insurance and annuities, certain IRAs and qualified plans, and—for married couples—property held as tenancy by the entireties, which is shielded from the creditors of either spouse individually. Layering these correctly is where real planning happens.
For wealthier families, the conversation often extends to irrevocable trusts, family limited partnerships, and—for clients with special-needs beneficiaries—specialized vehicles that protect both assets and benefits eligibility. A child or grandchild who receives an outright inheritance can lose access to needs-based government programs overnight; a special needs trust preserves the inheritance without disqualifying the beneficiary. These structures span state lines and benefit from counsel who can coordinate across jurisdictions rather than work one corner of the plan in isolation.
Common snowbird mistakes I see most often
- Claiming Florida domicile but living the New York calendar. Day counts and credit-card geography don’t lie. Intent without facts loses audits.
- Leaving out-of-state property in individual name. The ancillary probate surprise lands squarely on grieving heirs.
- Recycling a northern power of attorney. It may not satisfy Florida’s strict statutory requirements when an institution scrutinizes it.
- Ignoring homestead devise rules. Especially in blended families, the constitution can override your wishes.
- Funding the trust on paper but not in deed. An unfunded trust is an expensive empty box; the home must actually be retitled into it.
When to call a Florida estate planning attorney
If you own property in more than one state, recently relocated to Florida, are part of a blended family, or hold assets that warrant serious protection, your plan deserves a coordinated review rather than a patchwork of out-of-state documents. The cost of doing this correctly is a fraction of the cost of two probate proceedings and a contested estate.

Frequently Asked Questions
How many days can a snowbird spend in their old state before being taxed as a resident there?
Many high-tax states, including New York, treat you as a statutory resident if you maintain a residence there and spend more than 183 days in the state during the year. Even if you have established Florida domicile, crossing that threshold can subject you to that state’s income tax, so careful day-counting and documentation are essential.
Will my out-of-state property go through probate in Florida if I die a Florida resident?
Real estate is probated where it sits. Property in another state owned in your individual name triggers an ancillary probate proceeding in that state, separate from your Florida estate. The most reliable way to avoid this for snowbirds is a funded revocable living trust holding both the Florida and out-of-state property, or, for Florida real estate, an enhanced life estate (Lady Bird) deed.
Does establishing Florida domicile require filing anything specific?
Filing a Declaration of Domicile under Florida Statutes Section 222.17 with your county clerk is a strong, sworn affirmation that Florida is your permanent home. It is not strictly required, but combined with the Florida homestead exemption, a Florida driver’s license, voter registration, and updated estate documents, it builds a defensible domicile record if your former state audits you.
Can I leave my Florida home to anyone I want in my will?
Not always. Florida’s constitutional homestead devise restrictions limit how you can leave the property if you are survived by a spouse or a minor child. An improperly devised homestead can pass by operation of law and override your will, which is why blended families in particular should plan the homestead carefully with a Florida attorney.
Do I need a separate Florida power of attorney if I already have one from up north?
Usually, yes. Florida’s durable power of attorney statute (Chapter 709) has strict requirements and eliminated springing powers, so an out-of-state document may be rejected by Florida banks and institutions. Most dual-state clients are best served by a Florida-compliant power of attorney and health care surrogate, with parallel documents kept valid in their northern state.
