Planning for a second marriage in Florida means coordinating a prenuptial agreement with your estate plan so that both your new spouse and your children from a prior relationship are protected. Because Florida law gives a surviving spouse strong, hard-to-override rights—including an elective share and homestead protections—a prenuptial agreement and a carefully drafted will or trust must work together rather than at cross purposes. Done right, the two documents speak with one voice; done carelessly, they contradict each other and end up in probate court.
I have watched too many blended families discover, after a death, that Mom’s prenup and Dad’s old will told two different stories. The mismatch is rarely intentional. It happens because people sign a prenuptial agreement before the wedding, then never circle back to update the will, beneficiary designations, and deeds. For couples who own property in more than one state—say a longtime home up north and a new condo in Florida—the coordination problem multiplies.
Why Second Marriages Need Their Own Estate Planning Playbook
A first marriage usually has a simple default: everything to the spouse, then to the kids. A second marriage breaks that default. You may want your new spouse to live comfortably for the rest of their life, but you also want the house, the retirement accounts, or the family business to land with your own children—not your spouse’s children from a prior marriage, and not a future spouse your widow or widower might marry.
Florida’s intestacy and spousal-rights statutes do not assume that competing goal. If you die without coordinating your plan, the law applies its own formula, and in a blended family that formula almost never matches what you actually intended.
The Florida Spousal Rights That Catch People Off Guard
Three features of Florida law deserve special attention in any second marriage:
- The elective share. Under Florida Statutes Chapter 732, a surviving spouse may claim an “elective share” equal to 30% of the deceased spouse’s elective estate, regardless of what the will says. The elective estate is broad—it reaches certain trust assets, jointly held property, and accounts that pass outside probate. You cannot quietly disinherit a Florida spouse simply by writing them out of your will.
- Homestead restrictions. Florida’s constitutional homestead protection limits how you can leave your primary residence if you are survived by a spouse or minor child. If you are married and try to devise the homestead to anyone other than your spouse, the devise can be invalid; the surviving spouse instead takes a life estate (or, by election, a one-half tenancy in common) under Florida Statutes 732.401.
- The family allowance and exempt property. A surviving spouse and certain children are entitled to a family allowance and to exempt personal property under Florida Statutes 732.402 and 732.403, which also sit outside the reach of an ordinary will.
These rights are precisely what a prenuptial agreement is designed to address. A valid prenup can waive the elective share, homestead rights, family allowance, exempt property, and rights to intestate succession—but only if it is drafted to do so explicitly and executed correctly.
How a Florida Prenuptial Agreement Interacts With Your Estate Plan
Think of the prenuptial agreement as the constitution and the estate plan as the legislation. The prenup sets the boundaries—what each spouse waives, what each spouse keeps, what each spouse is promised at death or divorce. The will, revocable trust, and beneficiary forms then carry out those promises.
Florida adopted the Uniform Premarital Agreement Act, codified at Florida Statutes Chapter 61 (sections 61.079 and following). A premarital agreement must be in writing and signed by both parties, and it becomes effective upon marriage. It can govern property rights, spousal support (within limits), and the disposition of property at death. Critically, it can include a waiver of the rights I listed above.
What Makes a Florida Prenup Enforceable—and What Breaks It
A waiver of spousal rights at death carries a higher standard than a garden-variety contract term. Florida courts will set aside a premarital agreement if it was not executed voluntarily, or if it was the product of fraud, duress, coercion, or overreaching. A second key ground: the agreement was unconscionable when signed and the challenging spouse did not receive fair and reasonable disclosure of the other’s property and financial obligations, did not waive that disclosure in writing, and did not otherwise have adequate knowledge of those assets.
The practical lessons from decades of Florida case law are consistent:
- Disclose fully and in writing. Attach a schedule of assets and liabilities for each party. A waiver is far harder to attack when the record shows the signing spouse knew exactly what they were giving up.
- Give it time. An agreement presented the night before the wedding invites a duress argument. Sign weeks or months ahead.
- Use separate counsel. Each spouse should have an independent lawyer review the document. It is not legally mandatory, but it dramatically strengthens enforceability.
- Spell out the death provisions. A prenup that waives “all marital rights” but never mentions the elective share or homestead leaves room for argument. Name the statutes.
The Promise-Plus-Plan Structure
The strongest second-marriage plans pair a waiver with an affirmative gift. Instead of “my spouse waives everything and gets nothing,” the prenup says something like: “Spouse waives the elective share and homestead rights, and in exchange the deceased spouse’s revocable trust will provide spouse a life estate in the Florida condo and an income stream from a marital trust.” That structure satisfies the new spouse’s need for security while preserving the remainder for the children—and it is far less likely to be challenged because the surviving spouse received something real.
Trust Tools That Do the Heavy Lifting in Blended Families
For most second marriages, a revocable living trust does more useful work than a will alone, because it can hold property for a surviving spouse during their lifetime and then redirect the remainder to your own children. Two structures come up again and again.
The QTIP / Marital Trust
A qualified terminable interest property (QTIP) trust pays all income to the surviving spouse for life and, at the survivor’s death, passes the remaining principal to the beneficiaries you chose—typically your children. The surviving spouse cannot redirect the remainder to their own children or a future spouse. For a couple where one party brings substantially more wealth or a family business into the marriage, the QTIP is often the centerpiece.
Lifetime-Use Trusts for the Homestead
Because Florida homestead rules are so restrictive, the residence frequently needs its own treatment. A common approach gives the surviving spouse a life estate or a trust-based right to live in the home, with the property passing to the children afterward. This is exactly the kind of arrangement a prenup should authorize, since the spouse may need to waive or modify their constitutional homestead rights for the plan to hold.
These same lifetime-income concepts appear in other planning contexts too. New York families, for instance, use vehicles like a to preserve income while protecting eligibility for benefits—a reminder that “provide income now, protect the remainder later” is a theme that runs through estate planning everywhere, not just in second marriages.
The Dual-State Problem: When Your Property Spans Two Jurisdictions
Most of the second-marriage couples I work with are not lifelong Floridians. They are snowbirds, recent retirees, or out-of-state owners who bought a Florida place and now split the year. That creates a coordination headache no single document solves cleanly.
Here is why it matters. Florida governs real estate physically located in Florida, including homestead protection. But your domicile—the state you consider your true, permanent home—governs your tangible personal property and the administration of your estate. If you keep a house in New York and a condo in Naples, you may face ancillary probate: a second probate proceeding in Florida just for the Florida real estate, on top of the primary probate in your domicile state.
A prenuptial agreement signed in another state adds a wrinkle. Florida courts will generally honor a valid out-of-state prenup, but enforceability questions—especially around homestead—get analyzed under Florida law for Florida property. If your prenup was drafted by a lawyer who never contemplated Florida homestead rules, it may not actually waive what you think it waives once you make Florida your homestead.
A Coordination Checklist for Dual-State Couples
- Confirm your domicile. Florida has no state estate or income tax, which is often the reason people establish domicile here. But you cannot claim Florida’s benefits while keeping a New York driver’s license, voter registration, and primary home. Pick a domicile and make your records consistent.
- Re-paper the prenup for Florida. Either confirm the existing agreement validly waives Florida elective-share and homestead rights, or sign a Florida-compliant amendment.
- Use a revocable trust to avoid ancillary probate. Titling the Florida property in a trust can keep it out of a separate Florida court proceeding entirely.
- Align beneficiary designations. Retirement accounts and life insurance pass by designation, not by will. In a blended family these are the most commonly overlooked documents—and the most likely to send money to an ex-spouse you forgot to remove.
For property and asset-protection strategies that cross state lines, families with a New York footprint often coordinate with counsel there as well; structures such as a are designed to shield assets while planning for long-term care, and they need to be reconciled with whatever you put in place in Florida so the two plans do not work against each other.
Sequencing: What to Sign, and in What Order
Order matters more than people expect. The prenuptial agreement should be negotiated and signed before the wedding, with full disclosure and independent counsel. Then, after the marriage, the estate plan should be drafted to honor the prenup’s promises—funding the marital trust, retitling the homestead, and updating beneficiary forms.
If you reverse the order, or if you sign a prenup and then let an old will sit unchanged for a decade, the documents drift apart. A will that leaves the homestead “to my children” is void if Florida homestead law gives it to your spouse, and a prenup waiver that the will never references may never get implemented. Coordination is not a one-time event; revisit the package after any major change—a new property purchase, a move that shifts your domicile, the sale of a business, or the birth of a grandchild you want to provide for.

The Bottom Line
A second marriage in Florida is not just a personal milestone—it is an event that quietly rewrites your legal defaults. The elective share, homestead protection, and family allowance all exist to protect your new spouse, and they will override a will you never updated. A prenuptial agreement is the tool that lets you and your spouse decide, together and in advance, how those rights will be shaped. But it only works if your will, your trust, your deeds, and your beneficiary forms are then drafted to carry out the deal. Coordinate the documents, account for any out-of-state property, and revisit the plan when life changes. Your children and your new spouse will both thank you for it—because the plan will finally tell one consistent story.
Frequently Asked Questions
Can a prenuptial agreement waive a spouse's elective share in Florida?
Yes. Under Florida Statutes Chapter 61 (the Uniform Premarital Agreement Act) and Chapter 732, a valid prenuptial agreement can waive the 30% elective share, homestead rights, family allowance, exempt property, and intestate succession rights. The waiver must be in writing, executed voluntarily, and—to resist a later challenge—supported by fair and reasonable financial disclosure or a written waiver of that disclosure. Naming the specific rights being waived makes the agreement far harder to attack.
What happens to my Florida home if my will leaves it to my children instead of my spouse?
Florida’s constitutional homestead rules (Florida Statutes 732.401) restrict how you can devise your primary residence when you are survived by a spouse or minor child. A devise of the homestead to anyone other than your spouse can be invalid, and the surviving spouse instead receives a life estate—or may elect a one-half tenancy in common with your descendants. To leave the home to your children, the spouse generally must waive those homestead rights, typically through a prenuptial agreement or a deed-based arrangement.
How do dual-state couples avoid a second probate on their Florida property?
When you live primarily in another state but own real estate in Florida, your estate can face ancillary probate—a separate Florida court proceeding just for the Florida property. The cleanest way to avoid it is to title the Florida real estate in a revocable living trust, so the property passes under the trust rather than through court. Confirming your domicile and aligning your driver’s license, voter registration, and tax filings also prevents disputes over which state’s law governs.
Do I need to update my will after signing a prenuptial agreement?
Almost always, yes. The prenup sets the terms—what each spouse waives and what each is promised—but the will, revocable trust, deeds, and beneficiary designations are what actually carry those terms out. If you sign a prenup and leave an old will unchanged, the documents drift apart, and the plan may fail when it matters. Update the estate plan promptly after the marriage and revisit it after any major change in property, domicile, or family.
Will Florida courts honor a prenuptial agreement signed in another state?
Generally yes, Florida courts will recognize a valid out-of-state premarital agreement. But enforceability questions involving Florida real estate—especially homestead protection—are analyzed under Florida law. If your original agreement did not contemplate Florida’s elective-share and homestead rules, it may not effectively waive those rights once Florida becomes your homestead. Many couples have the agreement reviewed and, if needed, amended to be Florida-compliant after they relocate.
