Estate planning for snowbirds and dual-state residents is the work of coordinating your will, trusts, beneficiary designations, and legal domicile across two states so a single, conflict-free plan governs your assets at death. For people who split the year between Florida and a northern state, the central tasks are establishing Florida as your legal domicile, avoiding probate in more than one state, and using Florida’s strong creditor and homestead protections to your advantage. Done correctly, it can mean the difference between a clean transfer and years of dual-state litigation and avoidable state estate tax.
I have spent years untangling estates for clients who assumed that owning a condo in Fort Lauderdale and a house up north was a manageable arrangement. It usually is — until someone dies, and the heirs discover the plan never accounted for two sets of laws pulling in opposite directions. Below is how to get ahead of that.
Why Two States Is the Problem, Not Two Homes
The trouble is rarely the real estate itself. It is that each state believes it has a claim on you. Your home state of New York, New Jersey, or Connecticut wants to tax your income and, in some cases, your estate. Florida wants to welcome you and tax neither. When you straddle both, you invite each state to assert authority, and your estate plan has to resolve that tension before the courts do it for you.
Three distinct issues surface again and again:
- Domicile disputes. A high-tax state may argue you never truly left, exposing your estate to its income or estate tax.
- Ancillary probate. Real property titled in your individual name in a second state triggers a separate probate proceeding there.
- Conflicting documents. An old will drafted under New York law may not interact cleanly with Florida’s homestead and elective-share rules.
Each of these is solvable. None solves itself.
Establishing Florida Domicile (and Making It Stick)
Domicile is the single most consequential concept for snowbirds. You can have several residences, but only one domicile — the place you intend as your permanent home. Florida domicile is what unlocks no state income tax, no state estate tax, robust homestead protection, and generous creditor exemptions. But intent alone is not enough; high-tax states audit aggressively, and the burden often falls on your estate to prove the move was real.
Florida law gives you a formal tool to declare intent. Under Florida Statutes § 222.17, you may file a sworn Declaration of Domicile with the clerk of the circuit court in your county — for our clients, typically Broward County. That filing is powerful evidence, but it is a beginning, not a conclusion. The states you are leaving look at the totality of your life.
Concrete Steps That Build a Domicile Record
- File a Declaration of Domicile under § 222.17 in Broward County.
- Apply for Florida’s homestead exemption under Article X, Section 4 of the Florida Constitution for your Fort Lauderdale residence.
- Register to vote in Florida and actually vote here.
- Obtain a Florida driver’s license and register your vehicles in-state.
- Move your primary banking, financial advisors, and safe-deposit box to Florida.
- Update estate documents to recite Florida residency and be executed under Florida law.
- Spend more than half the year here, and keep records — calendars, travel logs, credit-card geography — that prove it.
The day-count matters enormously. Several northern states apply a statutory residency test that can tax you as a resident if you maintain a dwelling there and spend more than 183 days in-state, regardless of where you claim domicile. Snowbirds who fly back for a long summer should track days the way a pilot tracks fuel.
Avoiding Double Probate With a Revocable Trust
Here is the scenario I see most: a client dies domiciled in Florida but still owns a lake house in their individual name up north. Florida probate handles the Florida assets. The northern house, however, forces an ancillary probate — a second court proceeding, second set of fees, and second timeline, all governed by a state your heirs may no longer have any connection to.
The cleanest fix is a properly funded revocable living trust. You transfer out-of-state real property into the trust during your lifetime. At death, the trust — not a probate court — controls that property, and the ancillary proceeding disappears. A revocable trust also keeps your affairs private and provides for seamless management if you become incapacitated, which matters when you are physically in one state and your family is in another.
For clients with more complex holdings — closely held business interests, concentrated stock, or out-of-state rental portfolios — we often pair the revocable trust with additional planning vehicles. If you want to understand the range of options, this overview of trust planning structures is a useful starting point, and our Florida estate planning team can map them onto your specific two-state footprint.
Funding Is the Step Everyone Skips
A trust only avoids probate for assets actually titled in its name. An unfunded trust is an expensive paperweight. After signing, the out-of-state deed must be re-recorded into the trust, accounts must be retitled, and beneficiary designations on retirement accounts and life insurance must be reviewed for consistency. This administrative follow-through is where most do-it-yourself plans fail.
Florida’s Asset Protection Advantages for High-Net-Worth Snowbirds
For affluent clients, Florida is not just a tax haven — it is one of the most debtor-friendly states in the country, and that is a feature you should deliberately exploit once you are domiciled here.
- Homestead protection. The Florida Constitution shields an unlimited-value primary residence (on up to half an acre within a municipality) from most creditors. There is no dollar cap, unlike the modest homestead exemptions in many northern states.
- Tenancy by the entireties. Married couples can title assets so that a creditor of only one spouse cannot reach them.
- Annuities and life insurance. Under Florida Statutes §§ 222.13 and 222.14, the proceeds and cash value of life insurance and annuity contracts receive strong protection from creditors.
- Retirement accounts. Qualified plans and IRAs are broadly protected under Florida law.
These protections turn on Florida residency. A snowbird who fails to firmly establish domicile may find that a northern court applies its own, weaker rules. Asset protection and domicile planning are two sides of the same coin.
Coordinating Documents Across State Lines
Every dual-state client should ensure their core documents are valid and recognized in both jurisdictions, and that they speak with one voice. At minimum, revisit:
- A last will and testament executed under Florida law. Note that Florida does not recognize holographic or nuncupative wills, and out-of-state wills must meet Florida’s execution formalities to be self-proved here. Start with our overview of Florida wills if yours predates your move.
- A durable power of attorney drafted to satisfy Florida’s exacting requirements under Chapter 709, Florida Statutes — Florida abolished “springing” powers of attorney and demands specific superpower language for certain acts.
- A designation of health care surrogate and living will valid in both states.
- Updated beneficiary designations consistent with the rest of the plan.
One overlooked trap: Florida’s homestead devise restrictions. If you are survived by a spouse or minor child, the Florida Constitution sharply limits how you can leave your homestead, and a will provision drafted in another state can be invalidated outright. This is precisely the kind of conflict that surfaces only in Florida probate, when it is too late to fix.
Special Situations Demand Specialized Trusts
Some families carry planning needs that follow them across state lines. A child or grandchild who receives government disability benefits, for example, requires careful structuring so an inheritance does not disqualify them from assistance. A dedicated special needs trust preserves eligibility while still providing for that beneficiary — and the rules differ by state, so coordination between your Florida and northern counsel is essential.
A Practical Annual Checklist for Snowbirds
Treat your two-state plan as a living arrangement, not a one-time event. Each year, before you head south, confirm:
- Your day-count is on track to support Florida domicile.
- Any newly acquired out-of-state property has been titled into your trust.
- Beneficiary designations still match your overall plan after life changes.
- Your homestead exemption filing is current in Broward County.
- Your powers of attorney and health care directives remain valid in both states.
Estate planning across two states is not complicated because the law is mysterious. It is complicated because two bodies of law are operating at once, and a plan that ignores one of them quietly stores up problems for the people you love. If you split your year between Florida and somewhere colder, the time to align everything is now — while you are healthy and the choices are yours to make.

Frequently Asked Questions
How many days do I need to spend in Florida to be considered a resident for tax purposes?
There is no single magic number, because domicile is about intent shown through your whole life, not just days. However, many high-tax northern states apply a statutory residency test that can tax you as a resident if you keep a home there and spend more than 183 days in-state. Practically, snowbirds should spend more than half the year in Florida and keep detailed records to prove it.
Will my out-of-state will be valid in Florida?
A will validly executed in another state is generally honored in Florida, but it may not be self-proved here and can run into Florida-specific rules. Florida does not recognize handwritten (holographic) or oral wills, and its homestead devise restrictions can invalidate provisions that were fine in your prior state. After establishing Florida domicile, it is wise to have your will reviewed or re-executed under Florida law.
How do I avoid probate in two states when I own property in both?
Fund a revocable living trust and transfer your out-of-state real property into it during your lifetime. Because the trust owns the property at death, it passes outside of probate, eliminating the separate ancillary probate proceeding that individually titled out-of-state real estate would otherwise trigger.
What is a Declaration of Domicile and do I need one?
Under Florida Statutes Section 222.17, a Declaration of Domicile is a sworn statement filed with the circuit court clerk declaring Florida as your permanent home. It is strong evidence of intent and highly recommended, but it is not conclusive on its own. You should pair it with concrete steps like a Florida driver’s license, voter registration, and the homestead exemption.
Does Florida protect my assets better than my northern state?
For most high-net-worth individuals, yes. Florida offers unlimited-value homestead protection, tenancy by the entireties for married couples, and strong creditor protection for life insurance, annuities, and retirement accounts. These protections depend on genuinely establishing Florida residency, which is why domicile and asset protection planning go hand in hand.
