Estate planning for blended families in Florida means structuring your will, trusts, beneficiary designations, and homestead so that a surviving spouse and children from a prior marriage are each protected—rather than left fighting over the same assets after you die. Because Florida law gives a surviving spouse strong, hard-to-disinherit rights (an elective share, homestead protection, and pretermitted-spouse claims), couples in second or third marriages who do nothing often produce exactly the outcome they feared: one side inherits everything and the other side inherits a lawsuit. Good planning replaces that default with a deliberate, written arrangement.
I see this constantly with Palm Beach retirees and seasonal residents. Two people meet later in life, each with adult kids, a home up north, and a place down here. They love each other and assume “we’ll just leave it to each other.” Then the first spouse passes, and the survivor controls everything—free to spend it, remarry, or rewrite their own will to favor their own bloodline. The children of the first-to-die can be quietly written out. That is not a malicious plan; it’s the absence of one.
Why Blended Families Need Different Planning in Florida
A traditional family with one marriage and shared children usually has aligned interests: leave it to the spouse, then to the kids, done. Blended families have a built-in tension. Your spouse needs financial security for the rest of their life. Your children want to know that the inheritance you intended for them actually reaches them. Those two goals compete, and Florida’s statutes don’t resolve the conflict for you—they just hand significant leverage to the surviving spouse.
Three features of Florida law make this especially important to address head-on:
- The elective share. Under Florida’s probate code, Fla. Stat. § 732.201 and following, a surviving spouse may elect to take 30% of the “elective estate”—a broad pool that reaches well beyond the probate estate into many trusts, jointly held property, and certain accounts. A spouse can waive this right, but only through a valid written agreement. You cannot quietly cut a spouse out of it in your will.
- Homestead protection. Article X, Section 4 of the Florida Constitution and Fla. Stat. § 732.401 restrict how you can leave your Florida homestead when you have a surviving spouse or minor child. Even if your will says “give the house to my children,” that devise can be invalid. The surviving spouse may take a life estate with a remainder to your descendants, or elect instead to take a one-half interest as a tenant in common.
- Pretermitted spouse and child claims. If you marry after signing your will and don’t update it, Fla. Stat. § 732.301 may give your new spouse an intestate share anyway. A similar rule under § 732.302 protects children born or adopted after the will. Stale documents create surprise heirs.
The takeaway: in Florida you can’t simply disinherit a spouse by silence, and you can’t freely give the homestead away. Any blended-family plan has to be built with these rules, not around them.
The Snowbird and Seasonal-Resident Wrinkle
Many of our Palm Beach clients split the year between Florida and a northern state—New York, New Jersey, Ohio, Massachusetts. That raises a question that matters enormously for taxes and for which spouse’s rights apply: where are you actually domiciled?
Florida has no state estate tax and no state income tax, which is a major reason people establish domicile here. But domicile is about intent and conduct, not just a mailing address. If you claim Florida but spend most of your time and keep your “real life” up north, another state may assert that you remained domiciled there—dragging your estate back under its tax regime and its spousal-rights rules.
For blended families, this gets sharper because each state treats elective shares and homestead differently. New York, for example, has its own elective-share framework that operates nothing like Florida’s homestead rules. If you own property in two states, you may need coordinated planning in both. For New York–side issues, families often coordinate with counsel handling , while the Florida homestead and elective-share pieces are handled here. Establishing clean Florida domicile—voter registration, driver’s license, declaration of domicile, primary physician, the homestead exemption filing—does more than save tax. It clarifies which body of law governs the very rights your spouse and children will be arguing about.
Tools That Actually Work for Blended Families
The goal is almost always the same: provide for my spouse during their lifetime, then make sure what’s left goes to my children. A plain “I leave everything to my spouse” will cannot guarantee that second half. These structures can.
The QTIP Trust
A Qualified Terminable Interest Property (QTIP) trust is the workhorse of blended-family planning. You leave assets in trust rather than outright. Your surviving spouse receives all the income for life—and often access to principal for health, support, and maintenance—so they’re secure. But you name the people who inherit whatever remains when your spouse dies, and your spouse cannot change that. Typically the remainder goes to your children from your prior marriage.
The QTIP also qualifies for the unlimited marital deduction, so it defers federal estate tax until the second death while keeping control of the ultimate distribution in your hands. For a couple where each spouse wants to protect their own kids, mirror-image QTIPs are a clean solution. Many couples build these within a broader revocable so the structure governs assets without probate and stays private.
Life Insurance to “Carve Out” an Inheritance
Sometimes the simplest fix is to give each side its own pool. Use a life insurance policy—often inside an irrevocable life insurance trust—to fund an immediate inheritance for your children, while the rest of the estate supports your spouse. This avoids forcing the children to wait until the surviving spouse dies, which is the single biggest source of resentment I see. It also sidesteps fights over the house or the brokerage account because the kids’ share is a separate, liquid asset.
Prenuptial and Postnuptial Agreements
For couples marrying later in life, a prenuptial or postnuptial agreement that waives the elective share and homestead rights (with proper disclosure and formalities) is often the cleanest foundation. It lets each spouse keep separate property separate and frees you to leave assets to your own children without a surviving-spouse override. The waiver has to be done correctly—Florida courts scrutinize these—but a valid agreement removes the largest variable from the equation.
Beneficiary Designations and Titling
This is where good plans quietly fail. Retirement accounts, life insurance, annuities, and “transfer on death” accounts pass by beneficiary designation, not by your will or trust. If your IRA still names your first spouse, or names “my children” while your estate plan routes everything to your current spouse, those documents contradict each other—and the beneficiary form wins. Joint accounts with right of survivorship go straight to the survivor too. Every blended-family plan should include a full audit of how each asset is titled and who is named.
The Florida Homestead Trap
The Palm Beach house deserves its own section because it derails more blended-family plans than anything else. Suppose you owned your home before the marriage and intend to leave it to your adult children. Under Fla. Stat. § 732.401, if you’re survived by a spouse, you generally cannot devise that homestead freely. The default gives your spouse a life estate, with the remainder to your descendants—or your spouse may elect a 50% tenancy-in-common interest instead, leaving your children co-owning the house with your widow or widower.
Co-ownership between a surviving spouse and stepchildren is a recipe for conflict: who pays the taxes, who pays for the roof, can it be sold, who lives there in season. There are ways to plan around the homestead restrictions—certain transfers, a properly executed spousal waiver, or holding title so the constitutional protection is structured intentionally—but each has trade-offs and must be done by someone who handles Florida homestead law regularly. The Florida-side mechanics of homestead and probate are exactly the kind of work our colleagues handle at .
Naming the Right People to Be in Charge
Who serves as personal representative, trustee, and agent under your powers of attorney matters more in a blended family than anywhere else. Putting your new spouse in charge of a trust that benefits your children—or putting one of your children in charge of a trust that benefits your spouse—loads the dice for litigation. Common solutions include:
- Naming a neutral professional or corporate trustee to administer a QTIP, so neither side controls the other’s inheritance.
- Splitting roles—your spouse as health-care surrogate, an independent party as trustee.
- Defining trustee powers narrowly and documenting an ascertainable standard for distributions, so discretion can’t be weaponized.
The same care applies to your durable power of attorney and health-care surrogate. If you become incapacitated, you want decision-makers whose loyalties won’t paralyze the family during a crisis.
Putting It Together
A workable Florida blended-family plan usually combines several of these pieces: a revocable trust that holds your assets and avoids probate; a QTIP or similar marital trust to secure your spouse while protecting your children’s remainder; coordinated beneficiary designations; a clear homestead strategy; possibly a marital agreement waiving statutory rights; and a thoughtful choice of fiduciaries. None of it works in isolation, and all of it should be reviewed whenever you move, remarry, sell the house, or have a major change in health.
If you’re not sure your current documents do what you think they do—or you’ve never coordinated your Florida and northern-state planning—it’s worth a focused review.

Frequently Asked Questions
Can I disinherit my spouse in Florida if I want everything to go to my children?
Not by simply leaving them out of your will. A surviving spouse can claim the elective share—30% of the elective estate under Fla. Stat. § 732.201 and following—plus homestead and other protections. You can only override these rights through a valid prenuptial or postnuptial agreement with proper disclosure and formalities. Without that, Florida law gives your spouse significant rights regardless of what your will says.
What is a QTIP trust and why is it useful for blended families?
A Qualified Terminable Interest Property (QTIP) trust gives your surviving spouse income for life (and often access to principal for support) so they’re financially secure, while you—not your spouse—decide who inherits whatever remains. That remainder typically passes to your children from a prior marriage. It also qualifies for the marital deduction, deferring federal estate tax until the second death while keeping you in control of the ultimate distribution.
What happens to my Florida home if I leave it to my kids but I'm married?
Florida’s homestead rules (Article X, Section 4 of the Constitution and Fla. Stat. § 732.401) restrict that devise. If you’re survived by a spouse, the home generally cannot pass freely to your children. Your spouse may receive a life estate with the remainder to your descendants, or elect a 50% tenancy-in-common interest—meaning your spouse and children could end up co-owning the house. Planning ahead with counsel can avoid that conflict.
As a snowbird, does Florida or my northern state's law control my estate?
It depends on your domicile—your true, permanent home, determined by intent and conduct, not just where you spend winters. Establishing clean Florida domicile (declaration of domicile, driver’s license, voter registration, homestead exemption, primary physician) helps ensure Florida law and its lack of a state estate tax apply. If you own property in two states, you may need coordinated planning in both, because elective-share and homestead rules differ significantly between states.
Why do beneficiary designations matter so much in a blended family?
Retirement accounts, life insurance, annuities, and transfer-on-death accounts pass by beneficiary designation, not by your will or trust. If those forms name an ex-spouse or contradict your estate plan, the form controls and can defeat your intentions. Every blended-family plan should include a full audit of how each asset is titled and who is named as beneficiary.
