Avoiding common Florida estate planning mistakes means building a plan that survives contact with Florida’s unusual probate, homestead, and spousal-rights laws, rather than a plan copied from a generic online form. The costliest errors are rarely about taxes; they are about ignoring rules unique to Florida, such as the constitutional limits on devising a homestead and a surviving spouse’s right to an elective share. For blended families and second marriages in Palm Beach, getting these details wrong can quietly disinherit the people you most wanted to protect.
I’ve spent years watching well-intentioned plans fall apart in the probate courtroom in West Palm Beach. The will was signed. The trust was funded, more or less. And yet the estate still ended up in a fight, because of a detail Florida law treats very differently than most people assume. Below are the mistakes I see most often, and how to keep them out of your own plan.
Mistake #1: Treating a Florida homestead like ordinary property
This is the single most misunderstood issue in Florida estate planning, and it ambushes more families than any tax rule ever will. Your homestead is not just an asset you leave to whomever you choose. The Florida Constitution restricts how it can be devised.
Here is the trap in plain terms. Under Article X, Section 4 of the Florida Constitution and Florida Statute § 732.4015, if you are survived by a spouse or a minor child, you generally cannot leave your homestead to anyone else. You can devise it to your spouse only if there is no minor child. A devise that violates these rules is simply void, no matter how clearly your will is written.
When that happens, Florida Statute § 732.401 rewrites the result for you. The surviving spouse takes a life estate in the home, with the remainder passing to your descendants. Alternatively, the spouse may elect, within a tight statutory window, to take an undivided one-half interest as a tenant in common, with the other half going to your descendants.
For a second marriage, this is explosive. Picture a man in Palm Beach who remarries and wants his children from his first marriage to inherit the house, while letting his new wife live there. If he simply “leaves the house to the kids,” the devise is void, and his widow may end up co-owning the property with stepchildren who can’t stand her. Nobody is happy, and the lawyers get paid for years.
The fix is not a form. It’s deliberate planning: a properly drafted life estate, a qualified personal residence arrangement, an enhanced life estate (Lady Bird) deed, or in some cases a valid spousal waiver of homestead rights. Each has trade-offs, and the right choice depends on the family.
Mistake #2: Forgetting that a Florida spouse can override your will
Many people believe a will is the last word. In Florida, a surviving spouse can say otherwise. Under Florida Statute § 732.201, a surviving spouse may claim an elective share equal to 30% of the decedent’s elective estate, regardless of what the will says.
And this isn’t limited to probate assets the way many older plans assume. The modern elective estate reaches a broad pool, including certain revocable trust assets, jointly held property, and some pay-on-death accounts. You cannot reliably disinherit a spouse in Florida just by funding a trust and leaving them out of the will.
Second marriages are where this surfaces most. A spouse who agreed, informally, that “the assets go to your kids” can change course after death and elect the 30% share, upending the entire plan. The election must be made within strict deadlines, generally within six months of the notice of administration and no later than two years after death, but when it’s made, it controls.
If you and your spouse genuinely intend an unequal split, the answer is a prenuptial or postnuptial agreement with a valid, written waiver of elective share and homestead rights, executed with proper financial disclosure. A handshake is not a plan.
Mistake #3: Relying on a will alone and inviting probate
A will does not avoid probate. A will is a set of instructions for probate. If your plan is a will and nothing else, you’ve guaranteed your family a trip to the courthouse.
Florida probate is more involved than many states. Formal administration typically requires an attorney, takes months, becomes a public record, and costs real money. For blended families, the public, adversarial nature of probate is exactly the wrong venue, because it gives a disappointed heir or a former spouse a forum to contest.
A funded revocable living trust sidesteps formal probate for the assets it holds, keeps your affairs private, and lets a successor trustee step in without court supervision. The key word is funded. I’ve reviewed dozens of trusts that were beautifully drafted and completely empty, because no one ever retitled the accounts or the real estate into the trust. An unfunded trust is an expensive paperweight. If this is your situation, our overview of wills and trusts explains how the two documents work together.
Mistake #4: Letting beneficiary designations contradict your plan
Life insurance, IRAs, 401(k)s, and annuities pass by beneficiary designation, not by your will or trust. These designations are a parallel estate plan, and when they conflict with your documents, the designation usually wins.
The classic Florida disaster: a remarried man who never updated his 401(k) after his first divorce. He spent a decade and a fortune building a trust for his current wife and children. At his death, the entire retirement account went to his ex-wife, the named beneficiary he forgot about. While Florida has a statute that can revoke an ex-spouse’s designation in some circumstances, federal law (ERISA) often preempts it for employer plans, and you do not want your family litigating that question.
- Review every designation after any marriage, divorce, birth, or death in the family.
- Name contingent beneficiaries, not just a primary, so the asset doesn’t default to your estate.
- Coordinate designations with the trust so retirement-account tax planning and creditor protection actually work.
- Never name a minor child directly; that forces a court guardianship over the money.
Mistake #5: Botching will execution (the witness-and-notary trap)
Florida is strict about how a will is signed. Under Florida Statutes §§ 732.502 and 732.503, a will must be signed by the testator in the presence of two attesting witnesses, who must each sign in the presence of the testator and of each other. Get the ceremony wrong, and the document may be invalid.
Two related errors deserve mention. First, Florida does not recognize handwritten (holographic) wills unless they meet the same witnessing formalities, so a heartfelt handwritten note is usually worthless. Second, skipping the self-proving affidavit, the notarized add-on that lets the will be admitted without tracking down witnesses years later, turns an easy probate into a hard one. Sign it, and sign it correctly.
Mistake #6: Assuming divorce cleans up your estate plan
Divorce changes some things automatically and leaves others dangerously intact. Under Florida Statute § 732.507, provisions of a will that benefit a former spouse generally become void on divorce, and the will is read as if the ex-spouse predeceased you.
That sounds reassuring, until you see the gaps. The statute applies to wills, but coordinating rules and federal preemption can leave beneficiary designations, jointly titled accounts, and powers of attorney pointing at an ex-spouse. There is also a notorious wrinkle: the revocation rule keys off the marriage predating the will, so a document signed before the wedding may not be revoked by the later divorce at all. After any divorce, the entire plan needs a fresh look, not a presumption that the law handled it.
Mistake #7: Naming the wrong people in charge
Documents don’t administer themselves; people do. In a blended family, naming the wrong personal representative, trustee, or health-care surrogate can turn a sound plan into a slow-motion fight.
Two common missteps. First, appointing a new spouse as trustee over assets meant for children from a prior marriage builds an inherent conflict of interest into the plan, because the trustee benefits from withholding. A neutral or professional trustee, or a clear formula, often serves everyone better. Second, naming an out-of-state personal representative who doesn’t qualify: Florida limits who can serve, and a non-relative who lives outside Florida generally cannot be your personal representative.
Mistake #8: Doing nothing about incapacity
Estate planning isn’t only about death. If you become incapacitated without a durable power of attorney and a designated health-care surrogate, your family may have to petition for a guardianship, an expensive, public, court-supervised process that strips you of decision-making rights. A current durable power of attorney, health-care surrogate designation, and living will let the people you trust act immediately and privately. These are the documents you hope never to use and deeply regret not having.
How Florida planning compares, and where to get it right
Florida’s homestead and elective-share rules are unusual, but the underlying discipline, coordinating documents, titling, and designations, applies everywhere. For families with ties to other states, it helps to see how sophisticated planning tools work elsewhere. Morgan Legal’s discussion of a Medicaid asset protection trust in New York shows how long-term-care planning can shield assets, and their overview of a pooled income trust in New York illustrates a tool used to preserve benefits for those with disabilities. The concepts translate; the statutes don’t, which is why local counsel matters.

Frequently Asked Questions
What is the most common estate planning mistake in Florida?
Mishandling the homestead. Under the Florida Constitution and Statute 732.4015, you generally cannot devise your homestead to anyone other than your spouse if you are survived by a spouse or a minor child. A devise that violates this is void, and the property passes under Statute 732.401 instead, which frequently forces a surviving spouse and children (including stepchildren) into shared ownership.
Can I disinherit my spouse in Florida with a will or trust?
Not reliably. Florida Statute 732.201 gives a surviving spouse the right to an elective share equal to 30% of the elective estate, which reaches many trust, joint, and pay-on-death assets, regardless of what your will says. The main way to override this is a valid prenuptial or postnuptial agreement that waives elective share and homestead rights with proper financial disclosure.
Does a will avoid probate in Florida?
No. A will is a set of instructions for the probate court, not a way around it. To avoid formal Florida probate, people typically use a properly funded revocable living trust, beneficiary designations, and certain titling strategies. An unfunded trust does not avoid probate, so the assets must actually be retitled into it.
What happens to my will if I get divorced in Florida?
Under Florida Statute 732.507, provisions of your will that benefit a former spouse generally become void on divorce, and the will is read as if the ex-spouse predeceased you. However, this does not automatically fix beneficiary designations, jointly titled accounts, or powers of attorney, and the rule may not apply if the will was signed before the marriage. You should fully review your plan after any divorce.
Do I need a self-proving affidavit on my Florida will?
You should have one. Florida Statutes 732.502 and 732.503 allow a will to be ‘self-proving’ when the testator and two witnesses sign a notarized affidavit. This lets the will be admitted to probate without locating the witnesses years later, which simplifies and speeds up administration significantly.
