Estate planning for snowbirds and dual-state residents means building a plan that names one state as your legal domicile, then aligning your will, trusts, and asset titling so a single set of laws governs your estate. For most people who split the year between a northern home and Palm Beach, that domicile is Florida, chosen for its absence of a state income or estate tax and its strong homestead protections. The catch is that owning property or keeping ties in two states can trigger probate in both and invite a residency challenge from your former state, so the plan has to be deliberate, not assumed.
I have sat across the table from too many families who learned this the hard way. A widow in West Palm Beach thought her husband’s New York will “covered everything,” only to discover the couple’s lake house up north had to be probated separately under New York law, with a New York attorney, while she was grieving in Florida. The fix was never complicated. It just needed to happen before he died, not after.
Why Dual-State Living Complicates an Estate Plan
When you live your life in two states, two legal systems have a plausible claim on you. Each state defines residency a little differently for income tax, for estate tax, and for probate jurisdiction. That overlap is where the trouble lives.
The three pressure points I see most often:
- Domicile disputes. Your former high-tax state may argue you never truly left, then assess income or estate tax on your whole estate. New York, New Jersey, Connecticut, and Massachusetts are aggressive about this.
- Ancillary probate. Real estate is governed by the law of the state where it sits. A Florida will does not automatically transfer your New York condo, so your heirs face a second, parallel probate in the other state.
- Conflicting documents. Snowbirds frequently sign a will in one state and a power of attorney in another, then update one and forget the other. The documents end up contradicting each other.
For blended families and second marriages, every one of these problems multiplies. When children from a prior marriage and a current spouse both have a stake in the outcome, an ambiguous domicile or a stray out-of-state asset is exactly the kind of gap that turns into litigation.
Establishing Florida Domicile: More Than a Suntan
Domicile is your one true legal home, the place you intend to return to. You can have many residences but only one domicile, and that single choice drives which state taxes your estate and which court probates it. Florida is the destination of choice because it has no state income tax and no state estate or inheritance tax, and because the Florida Constitution gives a permanent residence powerful homestead protection.
But intent has to be proven with conduct. If you keep a northern driver’s license, vote up north, and spend most of the year there, a former state can and will challenge your claim. To make Florida domicile defensible, take concrete steps:
- File a Declaration of Domicile with the clerk of court in your Florida county under Florida Statutes section 222.17.
- Apply for the Florida homestead exemption on your Palm Beach residence (Florida Statutes section 196.031).
- Get a Florida driver’s license and register your vehicles in Florida.
- Register to vote in Florida and actually vote here.
- Update your estate documents, accounts, and mailing address to Florida.
- Track your days. Many former states use a 183-day test for statutory residency, so spending more than half the year in Florida matters.
None of these steps is sufficient alone. Courts look at the totality. The more of your life that visibly centers on Florida, the harder it is for an old state to drag your estate back across the line.
Avoiding Ancillary Probate on Out-of-State Property
Even with airtight Florida domicile, real property in another state remains under that state’s jurisdiction. If the northern house is titled in your individual name, your heirs will need an ancillary probate proceeding up there in addition to your main probate in Florida. That means two courts, two sets of legal fees, and two timelines.
The cleanest solution is usually a revocable living trust. When you transfer the out-of-state property into the trust, the trust owns it, not you personally, so there is nothing for either state’s probate court to administer. On your death, the successor trustee distributes everything privately under the terms you set, regardless of which state the asset sits in. This is one of the most common reasons I steer dual-state clients toward a funded trust rather than a will alone. A well-drafted trust can do work that a simple will cannot, and the planning principles carry over whether you are protecting a vacation home or, in other contexts, a vulnerable beneficiary through a special needs trust in New York.
Other tools that sidestep ancillary probate, depending on the state and the asset:
- Joint ownership with rights of survivorship on the non-Florida property, which passes the asset directly to the survivor (use cautiously in blended families, since it can cut out your own children).
- Lady Bird deeds (enhanced life estate deeds) for Florida property, which transfer the home at death without probate while preserving homestead and Medicaid benefits during life.
- Transfer-on-death designations where the other state allows them for real estate or vehicles.
To understand the full range of trust options and which structure fits a two-state estate, it helps to review how different trusts are used in practice before deciding.
The Blended-Family Layer: Protecting a Second Spouse and Your Own Children
This is where dual-state planning gets genuinely delicate. In a second marriage, you often want your surviving spouse to be cared for during their lifetime, and you also want what remains to pass to your children from a prior relationship. Outright joint ownership and “I love you” wills that leave everything to the survivor quietly defeat that goal. Once the survivor inherits outright, they can rewrite their own plan and leave your children nothing.
Florida adds a wrinkle that surprises people: homestead and the elective share. Under the Florida Constitution and Florida Statutes section 732.401, a surviving spouse has rights in the homestead that you cannot freely override by will, and the elective share statute (section 732.2065) entitles a surviving spouse to 30 percent of the elective estate. If you assume your trust can simply route the Florida house to your kids, Florida law may say otherwise.
The usual answer for blended families is a properly structured marital trust, sometimes a QTIP trust, that gives your spouse income and the right to live in the home for life, then directs the remaining principal to your children. Pairing that with a clear, signed marital or prenuptial agreement that waives or shapes the elective and homestead rights is what makes the plan hold up. Both spouses keeping coordinated documents across both states is non-negotiable here.
Coordinating Documents Across State Lines
Snowbirds end up with drawers full of paper signed in different states in different decades. A few coordination rules keep that clutter from becoming a crisis:
- Pick one governing will. Execute a single will under Florida law and revoke prior wills explicitly. A will valid in Florida is generally recognized elsewhere, but a stack of un-revoked old wills invites a contest.
- Use a Florida durable power of attorney. Florida has its own statutory requirements (Florida Statutes chapter 709), and out-of-state POAs are sometimes rejected by Florida banks. A Florida designation of health care surrogate (chapter 765) and living will round it out.
- Re-title accounts and update beneficiaries. Beneficiary designations on retirement accounts and life insurance override your will entirely. After a remarriage or a move, these are the most frequently overlooked documents.
- Keep a master inventory. List every asset, where it sits, and how it is titled, so your successor trustee and family are not hunting across two states.
If you also maintain ties to New York or another northern state, it is worth having counsel there review whether any local quirk affects your plan. The same coordination logic applies to property and family on the Florida side, which is why our team works through these issues in Florida estate planning with the two-state picture in view from the start.
A Practical Sequence for Snowbirds
If you are reading this in October, packing for Palm Beach, here is the order I would tackle things:
- Decide, intentionally, that Florida is your domicile, and document it.
- Build or update a revocable living trust and fund it with both your Florida and out-of-state real estate.
- Execute a fresh Florida will, durable power of attorney, health care surrogate, and living will, revoking old versions.
- Address the blended-family question head-on with a marital trust and, if appropriate, a marital agreement.
- Synchronize beneficiary designations and account titling with the plan.
- Review the whole thing every few years and after any move, marriage, birth, or death.
Two states do not have to mean two sets of problems. Handled correctly, dual-state living is an opportunity: you get Florida’s tax and creditor advantages while keeping the northern home you love. The work is in the details, and the details are very doable.

Frequently Asked Questions
Do I need a new will if I move to Florida as a snowbird?
Generally yes. While a will validly executed in another state is usually honored in Florida, you should execute a fresh will under Florida law that explicitly revokes prior wills. This avoids conflicts between old out-of-state documents, ensures your durable power of attorney and health care surrogate meet Florida’s statutory requirements, and reinforces your claim that Florida is now your legal domicile.
How do I prove Florida is my domicile so my former state cannot tax my estate?
Domicile turns on intent shown through conduct. File a Declaration of Domicile under Florida Statutes section 222.17, claim the Florida homestead exemption, get a Florida driver’s license, register to vote and your vehicles here, update your estate documents and mailing address, and spend more than half the year in Florida. The more of your daily life that centers on Florida, the harder it is for a former high-tax state to challenge your status.
Will my out-of-state vacation home have to go through probate twice?
If the property is titled in your individual name, yes. Real estate is governed by the law of the state where it sits, so your heirs would face an ancillary probate there in addition to your main Florida probate. Transferring the property into a revocable living trust generally avoids this, because the trust owns the property and there is nothing for either probate court to administer.
How can I provide for my second spouse while still leaving assets to my children?
A marital trust, often a QTIP trust, lets your spouse receive income and live in the home for life, with the remaining principal passing to your children afterward. In Florida you must also account for the surviving spouse’s homestead rights and the 30 percent elective share under Florida Statutes section 732.2065, which is why a coordinated marital or prenuptial agreement is often part of the plan.
Does Florida have a state estate or inheritance tax?
No. Florida imposes no state income tax and no state estate or inheritance tax, which is a primary reason snowbirds establish Florida domicile. Your estate may still be subject to the federal estate tax if it exceeds the federal exemption, so larger estates should plan for that separately, but the Florida-level tax burden is zero.
