You’ve established Florida residency. You spend most of the year in Palm Beach or Naples. You file your taxes from a Florida address, you’ve updated your driver’s license, and you’ve got a Declaration of Domicile on record with the county clerk.
But you still own the house in Connecticut. Or the apartment in Manhattan. Or the lake place in Massachusetts.
What happens to your estate?
The answer is more complicated than most people expect — and the complications don’t surface until after you’re gone, when your family is the one dealing with them.
The Core Problem: One Person, Multiple States, Different Rules
When you die owning real property in more than one state, your estate doesn’t get processed in one clean probate proceeding. Each state where you own real property has jurisdiction over that property, regardless of where you were domiciled.
This means your estate may go through ancillary probate — a secondary probate proceeding in every state where you held real estate, in addition to the primary probate in your state of domicile.
If you’re domiciled in Florida and own a condo in New York, your estate faces:
- Primary probate in Florida — covering your personal property, financial accounts, and your Florida home
- Ancillary probate in New York — covering the New York condo, governed by New York law
Each proceeding has its own timeline, its own attorney, its own court fees, and its own rules about how property passes. For families already navigating grief, adding a second (or third) state’s legal system is a meaningful burden.
What Ancillary Probate Actually Costs
Ancillary probate isn’t just an administrative formality. It adds real costs and delays:
- Attorney fees in each state. You’ll need counsel licensed in each jurisdiction where probate is filed. Expect $5,000 to $25,000 or more per state, depending on the complexity and the value of the property.
- Court filing fees and costs vary by state but typically run $500 to $2,000.
- Timeline extension. Primary probate in Florida can take 6 to 12 months. Ancillary proceedings in other states run in parallel but often take longer, because they depend on the primary proceeding and involve coordination between courts.
- Publication requirements. Many states require notice to creditors through legal publication, adding weeks to the timeline.
For an estate with properties in three states, the total probate cost can easily double compared to a single-state estate of the same value.
Florida’s Homestead Exemption: A Powerful but Misunderstood Protection
Florida’s homestead protection is one of the strongest in the country — but it only applies to your Florida home, and it comes with rules that surprise people.
Under Article X, Section 4 of the Florida Constitution, your primary residence is:
- Exempt from forced sale by creditors (with exceptions for property taxes, mortgages, and mechanics’ liens)
- Protected from being devised freely if you have a surviving spouse or minor children
That second point catches people off guard. If you’re married and domiciled in Florida, you cannot simply leave your homestead to anyone you choose. Your surviving spouse has the right to either:
- A life estate in the property (the right to live there for the rest of their life), or
- An undivided one-half interest in the property as a tenant in common
This means your will cannot override your spouse’s homestead rights. If your estate plan assumes you can leave the Florida home to a child or a trust while your spouse is alive, that plan may not hold up under Florida law.
Your Connecticut or New York property, by contrast, is governed by those states’ rules — which may be entirely different.
Forced Heirship and Elective Share: Where States Diverge
Different states have fundamentally different philosophies about what a surviving spouse and children are entitled to receive from an estate.
Florida is an equitable distribution state with a 30% elective share. A surviving spouse can claim 30% of the “elective estate” — which includes not just probate assets but also certain trust assets, joint accounts, and other non-probate transfers. The decedent controls the other 70%.
Louisiana is the outlier. It’s the only state with forced heirship in the civil law tradition. Children under 24 (or children of any age with certain disabilities) are “forced heirs” entitled to a portion of the estate. Depending on the number of forced heirs, the decedent may only freely dispose of one-quarter to three-quarters of the estate. Louisiana Civil Code Articles 1493–1495 govern these rules.
New York provides an elective share of the greater of $50,000 or one-third of the net estate. New York also has specific rules about what counts toward the elective share — revocable trusts, joint accounts, and certain lifetime transfers can all be pulled back in.
What this means in practice: If you own property in multiple states, the distribution of your estate may be governed by different rules in each jurisdiction. Your Florida home follows Florida’s homestead and elective share rules. Your New York co-op follows New York’s. Your Louisiana family camp follows Louisiana’s forced heirship rules.
A single estate plan that doesn’t account for these differences is an estate plan with gaps.
The Domicile Dispute Risk
When significant estate tax is at stake, states have a financial incentive to claim your domicile.
Consider the numbers. States collectively collected approximately $6.7 billion in estate and inheritance taxes in 2021, according to the Tax Policy Center. New York alone collected roughly $1.5 billion. These aren’t rounding errors in state budgets — they’re line items worth fighting over.
If your estate is worth $15 million and you split your time between Florida and New York, New York’s Department of Taxation and Finance has every reason to argue that your true domicile was New York at the time of death. The New York estate tax on a $15 million estate — with its aggressive “cliff” structure — could exceed $1.5 million.
Florida’s constitutional prohibition on estate taxes means it has no financial incentive to claim your domicile. The dispute is always one-directional: the taxing state argues you were theirs, your estate argues you were Florida’s.
The evidence that matters in these disputes:
- Where you spent the majority of your time (the 183-day question)
- Where you voted, held your driver’s license, and registered vehicles
- Where your primary physicians, accountants, and attorneys were located
- Where your will was executed and which state’s law governs it
- Whether your records were created contemporaneously or reconstructed after the fact
That last point is critical. A GPS-verified daily record of where you actually were — created automatically, not assembled from credit card statements after a state audit letter arrives — is qualitatively different evidence than a calendar your family pieces together from memory.
How Children’s Residency Affects the Picture
Your estate tax liability is determined by your domicile, not your children’s. But your children’s state of residence affects what they actually receive.
Inheritance taxes are levied on the beneficiary, not the estate. Six states impose them: Iowa (phased out as of 2025), Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. If your children live in one of these states, their inheritance may be subject to state inheritance tax even if your estate was domiciled in Florida and paid no estate tax.
The rates vary significantly by relationship. In New Jersey, spouses and children (Class A beneficiaries) are exempt. But siblings, nieces, nephews, and non-relatives can face rates of 11% to 16%. In Pennsylvania, even children pay 4.5% on inheritances, and siblings pay 12%.
This means the total tax burden on a wealth transfer isn’t just a function of where you live — it’s also a function of where your heirs live. Estate planning that accounts for this can use trusts, timing of distributions, and other structures to minimize the combined federal, state estate, and state inheritance tax exposure.
Planning Strategies for Multi-State Property Owners
If you’re domiciled in Florida and own real property in other states, several strategies can reduce the complexity and cost your estate faces:
1. Hold Out-of-State Property in a Revocable Trust or LLC
Real property held in a properly structured trust or LLC doesn’t go through probate in the state where it’s located — because the trust or LLC, not you personally, owns the property. This eliminates ancillary probate entirely.
This is one of the most common and effective strategies for multi-state property owners. It requires proper setup with an attorney familiar with both Florida law and the law of the state where the property is located.
2. Execute a Florida Will and Update Governing Law
If your existing will was drafted under New York or Connecticut law, update it. A new will executed in Florida, governed by Florida law, with Florida witnesses, sends a clear signal about your domicile. It also ensures your personal property and Florida assets are administered under the rules you intended.
3. Consider Selling or Gifting Out-of-State Property
The simplest way to avoid ancillary probate and multi-state estate tax exposure is to not own real property in states with estate taxes. If you’re keeping a Manhattan apartment for occasional use, renting may be more efficient from an estate planning perspective than owning.
4. Coordinate Beneficiary Designations Across States
Retirement accounts, life insurance, and payable-on-death accounts pass outside of probate entirely. Making sure these designations are current and consistent with your overall estate plan avoids situations where probate assets follow one set of rules and non-probate assets follow another.
5. Maintain Clear Domicile Documentation
A Declaration of Domicile, updated legal documents, and a continuous record of days spent in Florida all reinforce your domicile position. This documentation protects your estate not just from income tax audits during your lifetime, but from estate tax claims after your death.
A Note on Professional Guidance
Multi-state estate planning sits at the intersection of tax law, property law, and trust law across multiple jurisdictions. The interactions between federal estate tax, state estate tax, state inheritance tax, homestead protections, elective share rules, and forced heirship provisions are genuinely complex.
This post provides a framework for understanding the issues. The specific strategies — trust structures, entity planning, gifting strategies, and the timing of property transfers — require an estate planning attorney who understands the specific states involved in your situation.
Building Your Domicile Record Now
Every strategy discussed above becomes harder to defend without clear evidence of where you actually lived.
Multi-state domicile disputes are won or lost on the strength of the documentation — and the documentation has to predate the dispute. Records created after a state challenges your estate are inherently suspect. Records that were generated automatically, every day, for years before you died, are not.
Southbound builds that record passively. It tracks each day — in Florida or outside it — using your iPhone’s location services, and stores the data privately in your iCloud account. No servers, no accounts, no manual entries. Your Departure Budget tells you exactly how many more days you can spend outside Florida while maintaining the 183-day threshold.
The documentation your estate will need starts with the days you’re living right now. The earlier you start, the stronger the record.
