Estate Planning for Snowbirds and Dual-State Residents: A Florida Attorney’s Guide

Estate planning for snowbirds and dual-state residents is the process of structuring your domicile, wills, trusts, and property titles so that one state clearly governs your estate, your assets pass without conflicting court proceedings, and you are not taxed as a resident of two states at once. For Floridians who keep a home up North, the goal is almost always the same: establish Florida as your legal domicile, hold out-of-state real estate in a way that avoids a second probate, and make sure the documents you signed in another state actually work here.

I have spent years untangling estates for people who split their year between a condo in Boca and a colonial in Connecticut, or a place near the water in Naples and the family house outside Boston. The recurring theme is not that these clients failed to plan. They planned twice, in two states, with two sets of advisors who never spoke to each other. That is where the trouble starts.

Why dual-state living complicates your estate plan

Each state writes its own probate code, its own rules for what makes a will valid, and its own definition of who counts as a resident for tax purposes. When you live in two of them, those rulebooks overlap, and the overlap is where money and time leak out of an estate.

Three specific problems come up again and again:

• Ancillary probate. Real property is governed by the law of the state where it sits. If you die owning a house titled in your individual name in New York while domiciled in Florida, your family opens a Florida probate and a separate ancillary probate in New York just to transfer that one house. Two courts, two sets of fees, two timelines.
• Residency tax disputes. High-tax states do not give up residents quietly. New York, in particular, audits former residents aggressively, applying both a statutory-residence test (the 183-day rule plus a permanent place of abode) and a domicile test that looks at where your life is genuinely centered.
• Document portability. A health care proxy or power of attorney that is routine in Massachusetts may be read skeptically by a Florida hospital or bank. Wills are usually honored across state lines, but the execution formalities and self-proving affidavits differ.

Establishing Florida as your legal domicile

Florida is one of the most attractive domicile destinations in the country, and not by accident. There is no state income tax, no state estate tax, and no inheritance tax. The Florida Constitution, in Article VII, Section 5, prohibits a state income tax on individuals, and the state’s estate tax was repealed when the federal credit it relied on disappeared. For a couple coming from a state with both an income tax and an estate tax, the savings over a lifetime can dwarf every other planning decision they make.

But you do not become a Florida domiciliary simply by buying a condo and saying so. Domicile is the place you intend to be your permanent home, the place you return to, and courts and tax auditors weigh objective facts over your stated intent. The northern state you are leaving has every incentive to argue you never really left.

Practical steps that build a domicile record

No single act is decisive. What persuades an auditor is a consistent pattern. Work through this list deliberately:

1. File a Declaration of Domicile with the clerk of court in your Florida county, authorized under Florida Statutes Section 222.17.
2. Register to vote in Florida and actually vote here.
3. Obtain a Florida driver’s license and register your vehicles in the state.
4. Update your wills, trusts, and powers of attorney to recite Florida residency and be executed under Florida law.
5. Change the mailing address on your tax returns, financial accounts, passport, and insurance.
6. Move your treasured, irreplaceable belongings, the family photographs and heirlooms, to the Florida home.
7. Establish local ties: doctors, dentists, house of worship, club memberships, professional advisors.
8. Spend more than half the year in Florida and keep a contemporaneous record (calendar, travel receipts, phone-location data) to prove it.

If you own a Florida home you occupy as your primary residence, also file for the homestead exemption. It reduces your property tax, caps annual assessment increases under the Save Our Homes provision, and serves as powerful evidence of domicile. Homestead also carries unique creditor protection and inheritance rules under the Florida Constitution, which is a separate and important conversation if you have a spouse or minor children.

Handling out-of-state real estate without a second probate

The single most common avoidable mistake I see is a dual-state resident who has a Florida estate plan but still holds the northern house in individual name. When they pass, that house drags the whole family back into the other state’s probate court.

The cleanest fix is usually a revocable living trust. You transfer the out-of-state property into the trust during your lifetime, the trust owns it at your death, and no probate is required in either state because the asset never passes through a will. A well-drafted revocable trust is the workhorse of dual-state planning, and it is worth understanding how flexible these instruments can be. Our colleagues at Morgan Legal Group explain the mechanics well in their overview of , which maps closely to how we deploy them for Florida clients with northern property.

Trusts are not the only tool, though, and the right answer depends on the state where the property sits:

• Revocable living trust. Avoids probate in both states, keeps your affairs private, and lets one successor trustee manage everything from one set of instructions. My usual first recommendation.
• Joint ownership with right of survivorship. Simple and effective for spouses, but it only delays the problem by one death and can create gift-tax or capital-gains issues with non-spouses.
• Lady Bird (enhanced life estate) deed. Available in Florida and a handful of other states; transfers property at death without probate while you retain full control during life. Not recognized everywhere, so it rarely solves the out-of-state piece.
• LLC ownership. Useful for investment or rental property in another state, because membership interests are personal property governed by your domicile, potentially sidestepping that state’s ancillary probate.

Funding matters as much as drafting. A trust that exists on paper but never had the deed retitled into it accomplishes nothing. The recording of a new deed must follow the formalities of the state where the land sits, which is exactly why coordinated, two-state counsel is worth its fee. To see how a Florida-anchored plan handles this in practice, our walks through funding and retitling step by step.

Making your documents work in both states

Florida has firm rules on execution. Under Florida Statutes Section 732.502, a will must be signed by the testator and witnessed by two people who sign in the testator’s presence and in the presence of each other. Florida also permits a self-proving affidavit under Section 732.503, which lets the will be admitted to probate without tracking down witnesses years later. Many out-of-state wills are technically valid here but lack a Florida-compliant self-proving affidavit, which adds delay.

Watch these document-specific pitfalls:

• Holographic and oral wills. Florida does not recognize handwritten (holographic) wills that lack proper witnesses, nor oral wills, even if your prior state did. A will that was valid up North may falter here.
• Powers of attorney. Florida’s durable power of attorney statute, Chapter 709, requires specific language and two witnesses plus a notary. An old out-of-state form often will not be honored by Florida banks.
• Health care directives. Update your living will and health care surrogate designation to Florida forms under Chapter 765 so local hospitals act without hesitation.
• Elective share. Florida protects a surviving spouse with a 30% elective share of the elective estate under Section 732.2065, which can override the terms of a will. Couples with prior-state plans, second marriages, or premarital agreements should have this checked.

For clients who are aging into more complex needs, the planning conversation widens beyond documents into guardianship, long-term care, and Medicaid positioning. This is where intersects with snowbird estate planning, especially for residents who may need care in one state while domiciled in another.

Coordinating taxes across two states

The headline savings of Florida domicile is income tax, but estate tax is the quieter prize. Several northern states impose their own estate tax with exemption thresholds far below the federal level. Even if your estate is comfortably under the federal exemption, an estate tax could be owed in the other state on property located there, regardless of where you are domiciled.

A few principles to keep in mind:

• Real estate and tangible property are generally taxable by the state where they are located, so retitling northern property into a trust or LLC can change the analysis.
• Intangible assets, such as brokerage accounts, follow your domicile, which is one more reason to nail down Florida residency.
• Some states levy estate tax on a non-resident’s in-state real property, so the location of your remaining northern assets still matters even after you establish Florida domicile.

None of this replaces advice from a tax professional licensed in both states. The estate plan and the tax plan have to be drafted together, or one will quietly undermine the other.

A simple sequence to get it right

When a new snowbird client comes in, I tend to work through the same arc. You can use it as a checklist before we ever meet:

1. Decide which state will be your true domicile and commit to it with real facts, not just paperwork.
2. Inventory every asset and note which state it sits in and how it is titled.
3. Re-execute your core documents under Florida law: will, revocable trust, durable power of attorney, health care surrogate, and living will.
4. Retitle or re-deed out-of-state real estate to avoid ancillary probate.
5. File your Declaration of Domicile and homestead exemption.
6. Coordinate the estate and tax plans with advisors in both states so nothing conflicts.

If you want a deeper look at the building blocks, our pages on Florida wills and Florida probate cover the underlying mechanics, and you can always reach out to schedule a consultation to review your specific two-state situation.

Dual-state living should be a luxury, not a liability your family inherits. With one clear domicile, properly funded documents, and out-of-state property held outside of probate, your estate can settle in one place, under one set of rules, the way you intended.

Frequently Asked Questions

Do I need a separate will for my Florida home and my out-of-state home?

No. You should have one coordinated estate plan governed by your state of domicile, ideally Florida. Rather than separate wills, the better approach is a single revocable living trust that holds real estate in both states, which avoids a second ancillary probate where your out-of-state property sits. Multiple wills in multiple states tend to conflict and create litigation.

How many days do I have to spend in Florida to be considered a resident?

Spending more than 183 days in Florida helps, but day-counting alone does not make you a domiciliary. Florida domicile turns on intent shown through objective facts: a Declaration of Domicile under Section 222.17, a Florida driver’s license, voter registration, homestead exemption, and where you center your life. High-tax states like New York apply both a 183-day statutory test and a domicile test, so keep a documented record of your time.

Will my New York or New Jersey will be valid in Florida?

Usually yes, if it was validly executed under the law of the state where you signed it, Florida will generally honor it. However, it may lack a Florida-compliant self-proving affidavit under Section 732.503, which slows probate, and Florida does not recognize handwritten or oral wills. It is best to re-execute your will under Florida Statutes Section 732.502 after you relocate.

What is ancillary probate and how do I avoid it?

Ancillary probate is a second, separate probate proceeding opened in another state solely to transfer real estate you owned there. If you are domiciled in Florida but own a house up North in your individual name, your family faces probate in both states. You avoid it by holding the out-of-state property in a revocable living trust, an LLC, or, where recognized, a survivorship deed.

Does moving to Florida save my estate from estate tax?

Florida has no state estate or inheritance tax, so domiciling here removes Florida-level estate tax entirely. But several northern states impose estate tax on real property physically located within their borders even for non-residents, so property you still own there may remain exposed. Retitling that property and coordinating with a tax professional in both states is essential.
