Avoiding common Florida estate planning mistakes means understanding the state’s unique rules before you sign anything. Florida’s homestead protections, strict will-execution formalities, elective-share statute, and community-property quirks for new residents trip up even careful, high-net-worth families. The most expensive errors are usually not exotic; they are ordinary oversights that surface only after death, when they can no longer be fixed.
I have spent years sitting across the table from Palm Beach families untangling plans that looked fine on paper. The pattern repeats: a document drafted in another state, a trust that was never funded, a beneficiary form nobody updated, a homestead left to the wrong person. Below are the mistakes I see most often, why they matter under Florida law, and how to keep them from quietly dismantling your estate.
Mistake #1: Assuming an out-of-state will or trust still works in Florida
People who move to Palm Beach from New York, New Jersey, Illinois, or anywhere else often assume the estate plan they paid good money for travels with them. Sometimes it does. Often it does not work the way they expect.
Florida has its own execution requirements under Fla. Stat. § 732.502: a will must be signed by the testator at the end, in the presence of two witnesses, who then sign in the presence of the testator and of each other. A will valid where it was executed is generally honored here, but a few specific provisions translate poorly. The biggest one is the self-proving affidavit. Florida law (Fla. Stat. § 732.503) lets a properly notarized affidavit make a will “self-proved,” which means the probate court accepts it without tracking down witnesses years later. Many out-of-state wills lack Florida-compliant self-proving language, turning what should be a routine admission into a delay and an expense.
Holographic (handwritten, unwitnessed) wills are a separate trap. Florida does not recognize holographic wills even if they were valid in the state where they were written. A nuncupative (oral) will is likewise void here.
The fix is not glamorous: have a Florida attorney review and, in most cases, re-execute your core documents once you establish residency. While you are at it, update your durable power of attorney and health-care surrogate designation to Florida forms, because financial institutions and hospitals here scrutinize those closely.
Mistake #2: Misunderstanding Florida’s homestead protection
Homestead is the single most misunderstood concept in Florida estate planning, and the misunderstanding is dangerous precisely because the protection is so strong.
Florida’s homestead is really three different things layered on top of each other:
- Creditor protection. Under Article X, Section 4 of the Florida Constitution, your homestead is shielded from most creditors without a dollar cap on value (only acreage limits apply). This is a centerpiece of asset protection for affluent residents.
- A property-tax benefit. The homestead exemption and the Save Our Homes assessment cap reduce and stabilize your annual taxes.
- Restrictions on devise. This is where plans break. If you are survived by a spouse or minor child, the constitution and Fla. Stat. § 732.401 sharply limit how you can leave your home.
Here is the trap. A married person with a minor child cannot simply leave the homestead to anyone they choose. If a will tries to devise the homestead in violation of these rules, the gift fails, and the property passes by operation of law: typically a life estate to the surviving spouse with a remainder to descendants, unless the spouse timely elects a one-half tenancy in common instead. I have watched blended families discover, too late, that Dad’s careful plan to leave the house to his children from a first marriage was overridden because there was a surviving spouse and a minor child in the picture.
Trying to deed homestead into a revocable trust adds another wrinkle. It can be done correctly, and often should be, but doing it without attention to the devise restrictions and to whether the trust preserves creditor and tax protections is a recipe for litigation. Homestead deserves its own conversation, not a footnote.
Mistake #3: Creating a revocable living trust and never funding it
This is the most common high-net-worth mistake I see, and it is entirely self-inflicted.
A revocable living trust only controls the assets that are actually titled in its name. Signing the trust document is the easy half. Funding it — retitling brokerage accounts, bank accounts, real estate, and business interests into the trust — is the half people skip, forget, or never finish. An unfunded trust is an expensive binder on a shelf. The assets you left outside of it still go through Florida probate, which is exactly what you paid to avoid.
Funding mistakes I correct regularly:
- A new investment account opened after the trust was created, titled in the individual’s name, never moved in.
- An LLC or closely held business interest left in personal name because “we’ll handle it later.”
- A vacation property in another state never deeded to the trust, triggering a separate ancillary probate in that state.
- A pour-over will treated as the plan rather than the safety net it is meant to be.
Review your funding annually, and every single time you open a new account or buy property. A trust is a living instrument; treat it like one.
Mistake #4: Letting beneficiary designations override your entire plan
Your will and trust do not control retirement accounts, life insurance, or annuities. Those pass by beneficiary designation, and that designation beats your will every time. A meticulously drafted estate plan can be silently undone by a stale form from a decade ago.
The classic disaster is the ex-spouse who is still named on a $1.5 million IRA or a large life-insurance policy. Florida law (Fla. Stat. § 732.703) automatically voids certain beneficiary designations in favor of a former spouse after divorce, but the statute has important exceptions and does not reach every asset or every situation, particularly federally governed plans. Do not rely on the statute to clean up after you. Pull every beneficiary form, confirm it names who you actually intend, and coordinate it with your trust — especially for retirement accounts, where naming a trust as beneficiary has real income-tax consequences under current required-distribution rules and should be done deliberately, not by default.
Mistake #5: Ignoring the spousal elective share
You cannot fully disinherit a spouse in Florida. The elective share (Fla. Stat. §§ 732.201–732.2155) entitles a surviving spouse to 30% of the “elective estate,” a deliberately broad pool that reaches well beyond the probate estate to include revocable trust assets, certain transfers within a window before death, jointly held property, and pay-on-death accounts.
This matters enormously in second marriages and in plans that try to route wealth to children from a prior relationship. If you intend to leave a spouse less than 30%, that intention has to be papered correctly — typically through a valid prenuptial or postnuptial agreement with proper financial disclosure, or through planning vehicles a spouse has knowingly waived rights against. Skip that step and your survivor can blow up the plan after you are gone.
Mistake #6: Confusing tax planning with asset protection
Affluent clients often arrive focused on the federal estate tax. That focus is healthy, but it is only one risk. Florida imposes no state estate or inheritance tax, so for many families the federal exemption already covers the estate-tax exposure — though the exemption amount is set by federal law and changes over time, so the planning has to be revisited, not set and forgotten.
Asset protection is the separate discipline that high-net-worth Floridians under-plan. It addresses lawsuits, creditors, and liability, not the IRS. Florida is a strong asset-protection jurisdiction — homestead, tenancy by the entireties for married couples, and statutory protections for annuities and certain retirement accounts are powerful tools — but they have to be used intentionally and well before any claim arises. Layered structures matter here. Many of the same trust techniques apply across states, and our colleagues handle parallel planning in New York; for example, a shows how an irrevocable structure can shield assets from long-term-care costs when established within the applicable look-back period.
Don’t forget long-term care and special-needs planning
The cost that quietly erodes more estates than the estate tax is long-term care. A married couple with significant but not unlimited assets needs a plan for the surviving spouse’s care, and families supporting a disabled loved one need to protect public-benefit eligibility. Specialized instruments exist for this; a is one example of how surplus income can be sheltered without disqualifying a beneficiary from means-tested benefits. Florida has analogous tools, and they belong in the conversation early.
Mistake #7: Naming the wrong fiduciaries — or forgetting your incapacity plan
Estate planning is not only about death. Most people will spend a period incapacitated before they die, and that is where families get hurt first.
- Durable power of attorney. Florida’s statute (Fla. Stat. ch. 709) requires specific formalities and, crucially, no longer recognizes “springing” powers that activate on incapacity. The document must be durable and current. An out-of-date or non-compliant POA forces a guardianship proceeding — slow, public, and expensive.
- Health-care surrogate and living will. Name someone, name a backup, and make sure the documents meet Florida’s witnessing requirements.
- Choosing fiduciaries badly. Naming the oldest child by default, or a personal representative who lives out of state and is not a relative (Florida restricts who may serve), or co-trustees who do not get along, causes more grief than tax law ever does. Choose for judgment and availability, not birth order.
Mistake #8: Treating the plan as a one-time event
The final mistake ties all the others together. An estate plan is a snapshot of your life, your family, your assets, and the law on the day you signed it. Every one of those moves. A move to Florida, a new grandchild, a divorce, the sale of a business, a change in the federal exemption — any of these can quietly turn a good plan into a liability.

Frequently Asked Questions
Is my out-of-state will valid in Florida?
Generally yes if it was validly executed where you signed it, but Florida does not recognize handwritten (holographic) or oral wills, and many out-of-state wills lack Florida-compliant self-proving affidavits, which slows probate. After establishing Florida residency, have an attorney review and usually re-execute your core documents.
Can I leave my Florida home to anyone I want in my will?
Not always. If you are survived by a spouse or a minor child, Florida’s homestead devise restrictions (Fla. Stat. § 732.401 and the state constitution) limit how you can leave the property. An attempted devise that violates these rules fails, and the home passes by law instead — often a life estate to the spouse with a remainder to descendants.
Why isn’t my revocable living trust avoiding probate?
Almost always because it was never fully funded. A trust controls only assets titled in its name. Accounts and property left in your individual name still go through probate. Retitle everything into the trust and re-check funding whenever you open a new account or buy property.
Can I disinherit my spouse in Florida?
No, not unilaterally. Florida’s elective share gives a surviving spouse 30% of a broadly defined elective estate that reaches trust assets, joint accounts, and certain transfers. Leaving a spouse less than that requires a valid prenuptial or postnuptial agreement or a knowing waiver of those rights.
Does Florida have an estate or inheritance tax?
No. Florida imposes no state estate or inheritance tax. Only the federal estate tax may apply, and only to estates above the federal exemption, which changes over time. Most families’ larger threat is long-term-care cost and liability exposure, which is addressed through asset-protection planning rather than tax planning.
