Estate Planning for Snowbirds and Dual-State Residents in Florida

Estate planning for snowbirds and dual-state residents means coordinating your will, trust, powers of attorney, and healthcare directives so they hold up in both the state you spend winters in and the one you spend summers in. For most part-time Floridians, the core decisions are which state is your legal domicile, whether to title property in a revocable living trust to avoid a second probate, and whether your documents will actually be honored by hospitals, banks, and courts in either state. Done right, it spares your adult children a tangle of duplicate court proceedings, conflicting tax claims, and out-of-state paperwork during an already hard season.

If you are the adult child of parents who split the year between, say, New York and Naples, this is one of the most consequential planning conversations you can have with them. The mistakes here are quiet ones. They do not surface while your parents are healthy. They surface the week a parent is hospitalized in the “wrong” state, or after a death, when you discover the family home has to be probated twice.

What “domicile” actually means and why it controls everything

People use “resident” and “domicile” loosely, but the law does not. You can be a resident of two states at once. You can only have one domicile: the single place you treat as your true, fixed, permanent home and intend to return to. Domicile decides which state’s law governs your will, where your estate is primarily administered, and which state’s income and estate taxes apply.

This matters enormously for the classic snowbird, because the financial gap between states is large. Florida has no state income tax and no state estate or inheritance tax. New York, by contrast, imposes both an income tax and a state estate tax with a notorious “cliff”: under New York Tax Law, once a taxable estate exceeds roughly 105% of the state exemption, the exemption phases out entirely and the whole estate is taxed, not just the excess. For an aging parent with appreciated assets, establishing Florida domicile cleanly can be worth a great deal to the next generation.

But you do not get Florida tax treatment by buying a condo and a beach chair. A former home state can and does audit departing residents, and the burden is on your parent to show the move was genuine. The facts that matter include:

• Filing a Florida Declaration of Domicile with the clerk of court (authorized under Florida Statutes § 222.17) and recording it.
• Registering to vote in Florida and actually voting there.
• Getting a Florida driver’s license and registering vehicles in Florida.
• Updating the address on tax returns, financial accounts, passports, and Medicare/insurance.
• Filing for Florida homestead on the in-state residence (more on this below).
• Spending more than half the year physically in Florida and keeping records that prove it.

Half-measures are worse than no move at all, because they invite a residency audit that your parent has armed against themselves. The single biggest favor an adult child can do is make sure the paper trail matches the lifestyle.

The 183-day reality check

High-tax states pay attention to the calendar. New York, for example, can treat someone as a “statutory resident” for income tax if they keep a permanent place of abode in the state and spend more than 183 days there in a year, regardless of where they claim domicile. A single overnight can count as a day. Encourage your parents to keep a simple travel log; it is dull, and it is exactly the evidence that wins audits.

The trap most snowbirds never see: ancillary probate

Here is the scenario that catches families off guard. A parent dies as a Florida domiciliary, and the estate is probated in Florida. But the parent still owned real estate up north, titled in their own name. Real property is governed by the law of the state where it sits, so that out-of-state house cannot pass through the Florida probate. It requires a separate, second proceeding in the other state called ancillary probate.

Ancillary probate means a second court, often a second attorney licensed in that state, a second round of fees, and months of additional delay, frequently while the property sits empty and costs money. The reverse happens too: a New York domiciliary who owns a Florida condo in their own name forces the family into ancillary administration here in Florida under Chapter 734 of the Florida Statutes.

The cleanest fix is usually a revocable living trust. Property titled in the name of the trust is not owned by the deceased individual at death, so it passes under the trust terms without probate in either state. One document, funded properly, can eliminate both the home-state probate and the ancillary one. For families with property in more than one jurisdiction, a well-drafted, fully funded trust is often the single most valuable planning move. If your parents have New York ties as well as Florida ones, it is worth coordinating with attorneys who handle so the structure works on both ends.

The word “funded” is doing heavy lifting there. An unfunded trust is an empty box. Deeds have to actually be re-titled, and accounts have to be retitled or have beneficiary designations aligned. I have seen beautifully drafted trusts fail to avoid probate because no one ever moved the assets in. Funding is not paperwork you do once and forget; it gets revisited every time your parents buy or sell property.

Florida homestead: a powerful benefit with sharp edges

Florida’s homestead protection is one of the strongest in the country, and it does three different jobs that people constantly confuse:

1. Tax: a reduction in assessed value plus the “Save Our Homes” cap that limits annual assessment increases.
2. Creditor protection: under Article X, Section 4 of the Florida Constitution, a homestead is shielded from most creditors, with essentially no dollar cap on value (only an acreage limit).
3. Descent and devise restrictions: limits on who you can leave the homestead to if you are survived by a spouse or minor child.

That third item surprises families. Florida restricts how homestead property can be devised when there is a surviving spouse or a minor child, and an attempted gift that violates those rules can be overridden by operation of law, sometimes producing a result no one in the family wanted. A snowbird who remarried, or who has a child from a prior relationship, needs the homestead provisions of their plan reviewed by Florida counsel, not assumed. You also cannot claim homestead in two states at the same time; claiming Florida homestead while keeping a residency-based exemption up north is a common, and discoverable, error.

Documents that travel: powers of attorney and healthcare directives

Wills and trusts are about what happens after death. The documents that govern a medical crisis are the ones your family will reach for first, and they are the ones most likely to fail across state lines.

A Florida durable power of attorney is governed by Chapter 709 of the Florida Statutes, which has specific requirements: it must be signed before a notary and two witnesses, it springs into effect immediately rather than only upon incapacity, and certain “superpowers” such as making gifts or changing beneficiaries must be separately initialed. A power of attorney drafted for another state may be valid in theory but get rejected in practice by a Florida bank that does not recognize the form. The same friction runs the other way.

For healthcare, Florida uses a designation of health care surrogate (Florida Statutes Chapter 765) and a living will for end-of-life wishes. Other states use healthcare proxies and advance directives that look different. Hospitals are cautious; a surrogate form they do not recognize can slow down decisions in an emergency.

For a true dual-state family, the practical answer is usually to execute a matched set of documents valid in each state, kept current and accessible, rather than relying on one state’s form to be honored everywhere. If your parents also spend significant time in New York, having state-specific incapacity documents reviewed by attorneys who focus on closes the gap that hospitals and banks exploit.

What adult children should actually do

• Confirm a named, willing agent under a power of attorney that is valid in both states, and get copies before a crisis, not during one.
• Make sure the healthcare surrogate or proxy is current and that the named agent knows they were named.
• Ask where the originals are kept. A trust no one can locate is no trust at all.
• Get a HIPAA authorization so you can speak with doctors when the time comes.
• Keep a one-page summary of accounts, advisors, and document locations somewhere accessible.

Common dual-state mistakes I see again and again

• “We’ll deal with the deed later.” The out-of-state property never gets moved into the trust, and the family ends up in ancillary probate anyway.
• Two homestead claims. Keeping a residency exemption up north while claiming Florida homestead triggers clawbacks and penalties.
• One-state documents. A power of attorney that a Florida bank refuses, discovered the day a parent is incapacitated.
• Domicile on paper only. A Declaration of Domicile filed, but tax returns, voter registration, and travel days that all still point home.
• Stale beneficiary designations. Retirement accounts and life insurance that still name an ex-spouse or a deceased relative override whatever the will says.

None of these are exotic. They are ordinary oversights that compound because no single advisor is looking at the whole two-state picture. That coordination is the real work.

Building a plan that works in both places

A sound dual-state plan for an aging parent generally includes: a clear, defensible domicile (usually Florida, for tax reasons), a funded revocable living trust holding real estate in every state where they own property, a Florida-compliant will as a backstop, matched powers of attorney and healthcare directives for each state, and a homestead strategy that respects Florida’s devise restrictions. The point is not to generate documents; it is to make sure that when something goes wrong in either state, the right person can act without a courtroom.

Frequently Asked Questions

Do snowbirds need a separate will for each state?

Usually not. A single will valid in your state of domicile generally governs your estate, and a properly funded revocable living trust can carry real property in other states without a second will. What you do often need is a matched set of powers of attorney and healthcare directives for each state, because those incapacity documents are the ones most likely to be rejected across state lines.

What is ancillary probate and how do I avoid it?

Ancillary probate is a second probate proceeding in a state where the deceased owned real estate that was not part of the main probate. A snowbird who dies owning a home in their own name in another state forces the family into this second case, with extra fees and delay. Titling out-of-state real estate in a funded revocable living trust usually avoids it entirely.

How does my parent prove Florida is their domicile?

Florida lets you file and record a Declaration of Domicile under Florida Statutes section 222.17, but that document alone is not enough. The move has to be real: a Florida driver’s license, voter registration, vehicle registration, a Florida homestead claim, updated tax and financial addresses, and spending more than half the year in Florida, with records to prove it.

Can my parents claim homestead in two states at once?

No. You can only have one homestead. Claiming Florida’s homestead tax exemption while keeping a residency-based exemption in another state is a common error that can trigger clawbacks and penalties. Florida homestead also carries constitutional creditor protection and restrictions on who can inherit the property when there is a surviving spouse or minor child.

Will a power of attorney from another state work in Florida?

It may be legally valid yet still get refused in practice. Florida durable powers of attorney under Chapter 709 have specific execution and content requirements, and Florida banks and institutions are often reluctant to honor unfamiliar out-of-state forms. For dual-state families, executing documents that comply with each state’s law is the reliable approach.
