Estate Planning for Blended Families in Florida: Protecting a Spouse and Children From a Prior Marriage

Estate planning for blended families in Florida is the work of dividing your estate fairly between a current spouse and children from a prior relationship, while neutralizing the default rules—Florida’s elective share and homestead protections—that can quietly override your wishes. Done well, it usually means a combination of revocable trusts, marital agreements, and beneficiary designations rather than a simple will. Done poorly, or not at all, it almost guarantees that your spouse and your kids end up in probate court arguing over the same house.

If you own property in Florida but keep ties to New York—a winter home down south, a co-op back north, grandchildren in both states—the stakes are higher still, because two states’ laws can apply to the same estate. I’ve watched too many “we’ll just split everything” plans collapse the moment one spouse passes. Let me walk through how this actually works.

Why Blended Families Need More Than a Simple Will

The classic blended-family wish is some version of this: “When I die, my spouse should be taken care of for life, and whatever’s left goes to my children.” It sounds straightforward. The trouble is that an outright gift to your spouse and a promise to protect your kids are fundamentally at odds. Once assets pass outright to a surviving spouse, that spouse owns them—free to remarry, rewrite a will, disinherit your children, and leave everything to their own family. No moral obligation survives the transfer.

A plain “I leave everything to my spouse, then to my children” will does not bind the survivor. The remainder gift to your kids evaporates the instant your spouse takes title. This is the single most common and most painful mistake I see in second marriages.

There’s a second problem unique to Florida: the law gives a surviving spouse rights that no will can erase. Even if you intentionally leave your spouse little or nothing, Florida hands them powerful claims against your estate. You cannot plan a blended family in Florida without planning around these rules.

The Florida Elective Share: Your Spouse’s Statutory Floor

Under Florida’s elective share statute (Fla. Stat. §§ 732.201–732.2155), a surviving spouse is entitled to 30% of the elective estate, regardless of what your will or trust says. The elective estate is broad on purpose. It reaches well beyond your probate assets to capture revocable trust property, certain jointly held accounts, pay-on-death accounts, and even some assets you gave away within a year of death. The Legislature built it this way specifically to stop people from emptying the probate estate to disinherit a spouse.

So if you leave your three children everything and your new spouse nothing, your spouse can file for the elective share and claw back roughly a third of nearly everything you owned. For a blended family, that’s not a footnote—it’s the whole ballgame. It means your children’s inheritance is exposed unless you and your spouse have agreed, in writing, to something different.

That “in writing” piece matters. The most reliable way to alter the elective share is a valid prenuptial or postnuptial agreement in which each spouse waives or limits their elective-share and homestead rights, with full financial disclosure. A clean marital agreement is often the foundation that makes the rest of a blended-family plan possible.

Florida Homestead: The Trap Hiding in the Family Home

Florida’s homestead protections are famous for shielding a primary residence from creditors. Less appreciated is how aggressively homestead law restricts what you can do with that home at death.

Under Article X, Section 4 of the Florida Constitution and Fla. Stat. § 732.401, if you are survived by a spouse and a descendant, you generally cannot freely devise your homestead. Try to leave it outright to your kids—or to anyone other than your spouse—and the devise can be void. The default result is that your surviving spouse takes a life estate, with a vested remainder to your descendants. Or, under § 732.401(2), the spouse may elect within six months to take a one-half tenancy-in-common interest instead.

Picture the friction. Your spouse and your adult children now co-own the house, or your spouse holds it for life with your kids waiting in the wings. Who pays the taxes, the insurance, the new roof? Can the survivor sell and downsize? These are exactly the questions that drive blended families into litigation, often within months of the funeral.

There are clean ways through this:

• A spousal waiver of homestead rights in a properly executed marital agreement, allowing you to devise the home as you choose.
• Holding the homestead as tenancy by the entirety, so it passes automatically to the surviving spouse (be deliberate—this disinherits your children from the home).
• A qualifying devise to the spouse coordinated with trust planning for the rest of the estate.
• Buying separate housing or restructuring ownership so the home isn’t the contested asset.

The right answer depends on whose money bought the house and what you actually want to happen. There is no one-size solution.

The QTIP Trust: Care for Your Spouse, Protect Your Children

For most blended families, the workhorse tool is a marital trust—frequently a QTIP (Qualified Terminable Interest Property) trust—built inside your revocable living trust. The structure does exactly what the “everything then to my kids” will can’t.

Here’s the logic. At your death, assets fund a marital trust. Your surviving spouse receives all the trust income for life, and often access to principal for health, support, and maintenance. The spouse is genuinely cared for. But your spouse cannot redirect where the assets go after their death. When the surviving spouse passes, you—through the trust you signed—decide who inherits the remainder: your children, named by you, locked in.

A QTIP also carries a federal estate-tax advantage: it qualifies for the unlimited marital deduction, deferring estate tax until the second death. For larger estates, that flexibility is meaningful. (Florida has no separate state estate tax, which simplifies the picture for Florida-resident estates—but New York does impose its own estate tax, which matters enormously if you remain a New York domiciliary.)

The choice of trustee is where blended-family plans live or die. Naming your surviving spouse as sole trustee of a trust meant to protect your kids invites conflict. Many families use a neutral co-trustee or a professional fiduciary to hold the balance between a spouse who wants access and children who want the remainder preserved.

Don’t Forget the Pretermitted Spouse and Child Rules

Two more Florida defaults can ambush a stale plan. If you marry after signing your will and don’t update it, your new spouse may be a pretermitted spouse under Fla. Stat. § 732.301 and take an intestate share—as if you’d died without a will as to them. Similarly, a child born or adopted after the will is signed can qualify as a pretermitted child under § 732.302 and claim a share.

In blended families—where marriages and the documents often arrive years apart—these statutes routinely upend old wills. The fix is simple: review and re-sign your documents after every marriage, birth, or adoption.

Coordinate Beneficiary Designations With the Whole Plan

Your will and trust don’t control everything. Life insurance, IRAs, 401(k)s, and annuities pass by beneficiary designation, outside probate. In blended families, an outdated form is a frequent disaster—the ex-spouse still named on a six-figure policy, or all the retirement money flowing to one child by accident.

Walk through every account and ask: does this designation match the deal I struck with my spouse and my kids? Often the cleanest approach is to name your revocable trust or a dedicated subtrust as beneficiary, so the marital-trust protections apply to those assets too rather than dropping outright into someone’s hands.

A blended-family checklist I give clients:

1. Consider a prenuptial or postnuptial agreement addressing elective share and homestead.
2. Build a revocable trust with a marital/QTIP subtrust to care for your spouse and preserve principal for your children.
3. Decide the homestead question deliberately—waiver, entireties, or a structured devise.
4. Name a neutral or professional trustee where spouse and children have competing interests.
5. Update every beneficiary designation to match the plan.
6. Re-execute documents after any marriage, birth, adoption, or move between states.

The Dual-State Wrinkle: Florida Property, New York Roots

Many of the families I help split their lives between Florida and New York, and that crossover changes the analysis. Domicile—your true, permanent home—drives which state’s law governs your overall estate, your income taxes, and whether the New York estate tax applies. But real property is always governed by the law of the state where it sits. A New York domiciliary who owns a Florida condo can trigger Florida homestead rules on that condo and a separate ancillary probate in Florida.

That split creates planning opportunities and pitfalls in equal measure. Holding out-of-state real estate in a properly funded revocable trust often avoids a second, ancillary probate entirely. Establishing genuine Florida domicile can sidestep the New York estate tax—but only if you actually make the move on paper and in fact (days counted, licenses, voter registration, the works). Getting domicile wrong invites a residency audit and double taxation.

If your wealth, your spouse, or your children are anchored in New York, you want counsel comfortable on both sides of the line. For the New York piece—elder law, estate tax exposure, and long-term-care concerns—the team at Morgan Legal’s New York elder law practice handles exactly this kind of dual-state coordination. Families worried about nursing-home costs eroding what they leave behind should also look at a Medicaid asset protection trust in New York, which shelters assets while preserving an inheritance for children. For the Florida-side work, the firm’s Florida estate planning attorneys can align your Sunshine State documents with the rest of the plan.

Putting It Together

Estate planning for a blended family in Florida is not about choosing your spouse over your children or the reverse. It’s about engineering certainty—so a surviving spouse is provided for, your children’s inheritance is locked in, and Florida’s elective-share and homestead defaults don’t make the decision for you. A coordinated revocable trust, a thoughtful marital agreement, a deliberate homestead strategy, and current beneficiary forms turn a fragile promise into an enforceable plan.

If you own property in more than one state, build the plan with both states in view from the start. To begin, review your current documents against the checklist above, then sit down with an attorney who handles blended-family and dual-state estates.

Frequently Asked Questions

Can I disinherit my spouse in Florida if I want everything to go to my children?

Not entirely. Florida’s elective share statute (Fla. Stat. §§ 732.201–732.2155) gives a surviving spouse the right to 30% of your elective estate—which includes trust assets, joint accounts, and pay-on-death accounts—regardless of your will. The only reliable way to limit or waive that right is a valid prenuptial or postnuptial agreement signed with full financial disclosure.

What happens to my Florida home if I'm survived by both a spouse and children from a prior marriage?

Under Florida’s homestead rules (Fla. Const. Art. X, §4 and Fla. Stat. § 732.401), you generally can’t freely leave the home to your children. By default the surviving spouse receives a life estate with a remainder to your descendants, or the spouse can elect a one-half tenancy-in-common interest within six months. A spousal waiver or holding the property as tenancy by the entirety can change this result.

How does a QTIP trust help blended families?

A QTIP (Qualified Terminable Interest Property) trust pays your surviving spouse income for life—and often principal for health and support—while ensuring that whatever remains passes to the beneficiaries you chose, typically your children. Your spouse cannot redirect the remainder, and the trust qualifies for the federal marital deduction, deferring estate tax until the second death.

I live part of the year in New York and own property in Florida. Which state's law governs my estate?

Your domicile—your true permanent home—governs your overall estate and determines whether New York’s estate tax applies. However, real property is governed by the law of the state where it sits, so a Florida condo can trigger Florida homestead rules and a separate ancillary probate. Holding out-of-state real estate in a funded revocable trust often avoids that second probate.

Do I need to update my estate plan after remarrying?

Yes. Florida’s pretermitted spouse rule (Fla. Stat. § 732.301) can give a spouse you married after signing your will an intestate share, and the pretermitted child rule (§ 732.302) does the same for children born or adopted afterward. Review and re-execute your documents after any marriage, birth, adoption, or move between states.
