Planning for a second marriage in Florida means coordinating your prenuptial agreement and your estate plan so they say the same thing. A prenup can waive a surviving spouse’s elective share, homestead rights, and family allowance under Florida law, but only if it is drafted, signed, and integrated correctly with your will and trust. When the two documents conflict, or when one is silent, the result is the slow, expensive probate litigation that blended families are most prone to.
I have watched too many well-intentioned remarriages end in a courtroom fight between a surviving spouse and the children of a first marriage. Almost always, the problem was not bad faith. It was a prenuptial agreement and an estate plan that were drafted in separate silos, years apart, by people who never spoke to each other. This article walks through how those pieces fit together in Florida, and where they tend to come apart.
Why Second Marriages Need Their Own Estate Planning Approach
A first marriage usually has a simple default: everything goes to the spouse, then to the kids. A second or third marriage breaks that assumption. Now you may have your children, your spouse’s children, joint assets, separate premarital assets, and competing expectations about who inherits the house. Florida’s spousal protection statutes were written to prevent a spouse from being disinherited, but in a blended family those same protections can accidentally disinherit your own children.
The tension is structural. Florida wants to protect the surviving spouse. You may want to protect both the surviving spouse and the children from your prior marriage. Those goals are not automatically compatible, and the default rules do not split the difference for you. You have to design the split yourself.
The Surviving Spouse Rights You Cannot Ignore
Florida grants a surviving spouse several rights that override a will unless they are properly waived:
- Elective share. Under Florida Statutes Chapter 732, Part II, a surviving spouse may elect to take 30% of the deceased spouse’s “elective estate,” a broad pool that reaches well beyond the probate estate to include certain trusts, jointly held property, and pay-on-death accounts. This is the single biggest threat to a plan that intends to leave most assets to children.
- Homestead protection. Article X, Section 4 of the Florida Constitution restricts how you may devise homestead property when you are survived by a spouse or minor child. You generally cannot simply leave the marital home to your children if your spouse survives you.
- Family allowance and exempt property. Sections 732.402 and 732.403 give the surviving spouse a family allowance (up to $18,000) and certain exempt personal property ahead of other beneficiaries.
- Pretermitted spouse share. Under Section 732.301, a spouse you married after signing your will can claim an intestate share if the will does not provide for them and was not made in contemplation of the marriage.
Each of these can be modified or waived, but only through the right instrument signed at the right time. That instrument is usually the prenuptial agreement.
How a Florida Prenuptial Agreement Coordinates With Your Estate Plan
Florida adopted a version of the Uniform Premarital Agreement Act, codified at Florida Statutes Section 61.079. A valid prenup can do something a will cannot do on its own: it can have both spouses voluntarily waive the elective share, homestead devise restrictions, family allowance, exempt property, and the right to act as personal representative. Section 732.702 specifically authorizes the waiver of spousal rights through a written contract signed by the waiving spouse.
Here is the part couples miss. The prenup waives the rights; the estate plan then has to actually deliver the agreed arrangement. If your prenup says your spouse waives the elective share but will receive a $500,000 life insurance payout and a life estate in the condo, your trust and beneficiary designations must be built to produce exactly that. A waiver with no corresponding gift is how a surviving spouse ends up with far less than promised, and a corresponding gift with no waiver is how children end up with far less than promised.
What “Coordination” Actually Means in Practice
Coordinated planning for a second marriage usually involves four moving parts working in concert:
- The prenuptial agreement defines what each spouse keeps as separate property, what becomes marital, and which statutory rights are waived at death.
- The revocable living trust carries out the death-time promises, often funding a marital trust or QTIP-style share for the surviving spouse with the remainder passing to your children.
- Beneficiary designations on life insurance, IRAs, and annuities are updated to match. A stale beneficiary form naming an ex-spouse will quietly defeat the entire plan.
- The homestead strategy resolves the constitutional devise problem, frequently through a life estate for the surviving spouse with a remainder to the children, or a spousal waiver of homestead rights.
When clients ask why they cannot just sign a prenup and call it done, this list is the answer. The prenup is the contract. The estate plan is the delivery mechanism. You need both, and they need to be reconciled line by line.
The Homestead Problem in Blended Families
Florida homestead law deserves its own discussion because it surprises nearly everyone. If you own the marital home and you die survived by a spouse, you cannot freely devise that home to your children. If you try, Florida law converts the gift: your spouse receives a life estate, with the remainder to your descendants, or alternatively the spouse can elect a one-half tenancy in common. Either way, your children do not get clean title, and your spouse cannot sell without cooperation.
This is fertile ground for conflict. The surviving spouse wants to stay; the adult children want their inheritance liquidated. A life estate forces them into a forced partnership over a single asset, and they often dislike each other to begin with. The cleaner solutions are decided in advance: a homestead waiver in the prenuptial agreement, joint ownership structured deliberately, or a buy-sell mechanism funded by life insurance so the spouse can be bought out or the children can be cashed out without a fight.
Couples who have used a New York retained life estate or similar transfer in another state should know the Florida homestead analysis is different and constitutionally driven. For background on how a retained life estate functions in another jurisdiction, this overview of home transfers and retained life estates in New York is a useful comparison, but the Florida homestead rules control any Florida home.
Protecting Children From a Prior Marriage Without Cutting Out Your Spouse
The marital trust, often structured as a QTIP (qualified terminable interest property) trust, is the workhorse of second-marriage planning. The surviving spouse receives income, and sometimes principal, for life. On the spouse’s death, whatever remains passes to your children, not the spouse’s. This is the legal device that lets you provide for your new spouse without disinheriting your kids and without trusting the spouse to voluntarily leave them anything.
Other tools layer in depending on the family:
- Life insurance funding to give the spouse liquidity immediately so the rest of the estate can pass to children outright.
- Separate “his and hers” trusts for premarital assets, keeping bloodline property cleanly traceable.
- Independent trustees rather than naming the surviving spouse as trustee over a trust that benefits your children, which removes a built-in conflict of interest.
For special situations, such as a disabled spouse or beneficiary who relies on means-tested benefits, more specialized vehicles come into play. A pooled trust is one such option for preserving benefit eligibility; this explanation of a pooled income trust in New York illustrates the concept, though a Florida-licensed attorney must confirm how the equivalent planning works under Florida and federal Medicaid rules.
Timing and Validity: When the Prenup Gets Thrown Out
A prenuptial agreement that a court later invalidates is worse than no plan at all, because by then everyone has relied on it. Under Section 61.079, a Florida premarital agreement can be set aside if it was not signed voluntarily, or if it was unconscionable when signed and the challenging spouse did not receive fair and reasonable disclosure of the other’s assets, did not waive disclosure, and had no adequate independent knowledge of those assets.
The practical lessons are old but reliable:
- Sign well before the wedding, not on the eve of it, to defeat any duress argument.
- Exchange full, written financial disclosure and attach it as an exhibit.
- Use separate, independent attorneys for each spouse.
- Revisit the agreement and the estate plan after major life events, a new child, a business sale, a move to Florida from another state.
That last point matters for newcomers. A prenup signed in another state is generally enforceable in Florida, but the estate-planning consequences shift the moment you establish Florida domicile, especially on homestead and elective share. A document that worked perfectly in New Jersey may leave gaps once you are a Florida resident.
Putting the Plan Together
The throughline of good second-marriage planning is consistency. The prenuptial agreement, the revocable trust, the will, the deed to the home, and every beneficiary form should tell one coherent story. When they do, probate is short and the family stays out of court. When they contradict each other, the surviving spouse’s elective-share rights and the children’s expectations collide, and a judge ends up deciding what you should have decided yourself.
If you are remarrying, already remarried without a coordinated plan, or relocating to Florida with out-of-state documents, this is worth a focused review with a Florida estate planning attorney.

Frequently Asked Questions
Can a prenuptial agreement waive the Florida elective share?
Yes. Under Florida Statutes Sections 61.079 and 732.702, a properly executed prenuptial agreement can waive a surviving spouse’s elective share, along with homestead devise rights, family allowance, and exempt property. The waiver must be in a signed writing, and for the plan to work the estate documents should provide whatever the prenup promises the spouse in exchange.
What happens to our Florida home if I leave it to my children but my new spouse survives me?
Florida’s constitutional homestead rules generally prevent you from devising the home freely when a spouse survives you. The law typically gives the surviving spouse a life estate with a remainder to your descendants, or the spouse may elect a one-half tenancy in common. To avoid forcing your spouse and children into shared ownership, address the home in advance through a homestead waiver or a planned buyout structure.
Do I still need a will or trust if I already have a prenuptial agreement?
Yes. A prenup defines rights and waivers, but it does not distribute your assets at death. Your will, revocable trust, deeds, and beneficiary designations are what actually deliver the inheritance arrangement. The prenup and the estate plan must be coordinated so they do not contradict each other.
Is my out-of-state prenup still valid after we move to Florida?
A prenuptial agreement validly signed in another state is generally enforceable in Florida, but the estate-planning effects change once you become a Florida resident, particularly regarding homestead protection and the elective share. It is wise to have the agreement and your full estate plan reviewed by a Florida attorney after relocating.
How does a QTIP or marital trust help in a second marriage?
A marital trust, often a QTIP, lets you provide income and support to your surviving spouse for life while ensuring that the remaining assets pass to your own children when the spouse dies. It is the standard way to care for a new spouse without disinheriting children from a prior marriage and without relying on the spouse to voluntarily leave anything behind.
