Planning for a second marriage in Florida means coordinating your estate plan with a prenuptial agreement so that your new spouse and your children from a prior relationship are both protected. Because Florida law gives a surviving spouse powerful rights that override a will, a prenuptial agreement is often the only way to lawfully shape who inherits what. Done together, the prenup and the estate plan work as one instrument; done separately, they frequently contradict each other and end up in litigation.
If you are an adult child watching a widowed or divorced parent remarry, this is the conversation that quietly determines whether the family home, the retirement accounts, and the legacy your other parent helped build stay in the family or pass to a new spouse and, eventually, that spouse’s own children. It is not a comfortable subject. It is also one of the most consequential planning decisions your parent will ever make, and the window to do it cleanly closes the day they say “I do.”
Why Florida Treats Second Marriages Differently
Florida is unusually protective of surviving spouses. The state assumes that most people want to provide for the person they married, so it builds a floor of rights beneath every marriage that a will alone cannot remove. For a first marriage with shared children, that default usually matches what the couple wanted anyway. For a second or third marriage, where each spouse may have separate children, separate assets, and a separate sense of “what belongs to whom,” those same defaults can quietly disinherit the people your parent most wants to protect.
The core problem is simple. You can write a will leaving everything to your children, sign it, and feel finished. If you then marry, Florida law may hand a substantial share of your estate to your new spouse regardless of what that will says. The will did not change. The legal landscape under it did.
The Spousal Rights You Cannot Erase With a Will Alone
Several Florida statutory protections operate independently of, and sometimes in direct conflict with, a will or trust:
- 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. That elective estate is broad. It reaches far beyond probate assets to include certain trusts, jointly held property, and accounts with beneficiary designations. A spouse who is left out of the will can simply elect against it and take the 30%.
- The homestead. Florida’s constitutional homestead protections restrict how a primary residence can be devised when there is a surviving spouse or minor child. A married person generally cannot leave the homestead outright to their children if a spouse survives them; the spouse typically receives at least a life estate or, by election, a one-half tenancy in common.
- Family allowance and exempt property. The surviving spouse is entitled to a family allowance and to certain exempt personal property, again regardless of the will’s terms.
- The pretermitted spouse. If your parent signed a will before the marriage and never updated it, the new spouse may be treated as a “pretermitted spouse” and receive an intestate share, as though no will existed as to them.
Read those together and the conclusion is unavoidable. In a second marriage, the will is not the controlling document for spousal inheritance. The marriage is. And the single lawful tool for adjusting those statutory rights is a properly executed marital agreement.
What a Prenuptial Agreement Can and Cannot Do
A Florida prenuptial agreement, governed by the Uniform Premarital Agreement Act in Chapter 61 of the Florida Statutes, is the instrument that lets a couple opt out of these defaults by mutual consent. In an estate-planning context, a prenup’s most important function is the waiver of spousal death rights.
A well-drafted agreement can include a clear, specific waiver of the elective share, homestead rights, the family allowance, exempt property, and the right to serve as personal representative. Florida law requires that these waivers be express. A vague “each party keeps their own property” clause will not reliably waive the elective share or homestead, and courts have refused to imply waivers that were not spelled out.
What a prenup cannot do is rewrite itself after the fact or substitute for the estate plan. The prenup waives rights; the will and trust then direct where the property actually goes. If your parent’s prenup says the new spouse waives all claims to the lake house, but the will never affirmatively leaves that house to the children, the children may still face a fight. The prenup removes the obstacle. The estate plan has to do the conveying.
The Coordination Trap
Here is where most second-marriage plans break down. The couple hires a family-law attorney to draft the prenup before the wedding. Years later, the same person hires an estate-planning attorney to draft a will and trust. The two documents were never in the same room. They use different definitions of “separate property,” reference assets that have since been sold or retitled, and occasionally contradict each other outright.
When that happens, the contradiction becomes the lawsuit. A surviving spouse’s attorney will argue the later estate plan modified or revoked the prenup’s waivers. The children’s attorney will argue the opposite. The estate pays both sides to litigate a conflict that careful drafting would have prevented for a fraction of the cost. Coordination is not a luxury here. It is the entire point.
Building a Coordinated Plan: The Working Pieces
A second marriage handled well usually involves more than a prenup and a will. The most common architecture pairs the marital agreement with a trust designed specifically to provide for a surviving spouse during life while preserving the remainder for the children.
- Prenuptial agreement with explicit estate waivers. Drafted with the eventual estate plan in mind, defining separate and marital property the same way the will and trust will.
- Revocable living trust. Holds the bulk of the estate, avoids Florida probate, and keeps the distribution scheme private rather than part of the public court record.
- A marital or QTIP trust. A qualified terminable interest property trust can give the surviving spouse income for life, and even a place to live, while guaranteeing that whatever remains at the spouse’s death passes to your parent’s children, not the spouse’s heirs. This is the classic “provide for my husband, protect my kids” structure.
- Updated beneficiary designations. Retirement accounts and life insurance pass by designation, not by will. These must be aligned with the prenup, and federal law adds a wrinkle: a spouse generally must consent in writing to being named off of an ERISA-governed 401(k), so the waiver language and the plan paperwork both have to be handled.
- Homestead strategy. Because the residence carries its own constitutional rules, the plan must address it deliberately, whether through a spousal waiver, a life estate, or holding the home in a way that respects the homestead constraints.
For families whose planning crosses state lines, this coordination grows more delicate. Many Boca Raton families keep ties to the Northeast, and assets or beneficiaries in another state can pull in different rules entirely. Tools used for long-term-care and special-needs planning, such as a or a , illustrate how trust design changes with jurisdiction and goal. Florida residents with Florida homestead and Florida domicile should coordinate any out-of-state structure with their documents so the two states’ rules do not collide.
Special Considerations When a Parent Remarries Later in Life
For adult children, the most useful framing is not “is this person good for Dad,” but “is the paperwork going to fight us in fifteen years.” Several issues recur in later-life remarriages.
The Family Home
The home is almost always the flashpoint. If your mother owned her house before the marriage and intends it to pass to you, the homestead rules can override that intention unless the new spouse waives those rights in the prenup. Without a waiver, the new spouse may receive a life estate, meaning your inheritance is frozen, and you cannot sell, until that spouse dies, which could be decades.
Long-Term Care and Asset Depletion
Marriage changes how nursing-home costs and Medicaid eligibility are calculated, because the law looks at combined resources. A new spouse’s eventual care could draw down assets your parent intended for you. A coordinated plan addresses who pays for whose care, and a prenup can establish that separate assets remain separate for these purposes.
Naming the Right Fiduciaries
Who serves as personal representative, trustee, and agent under the power of attorney becomes politically charged in blended families. Naming the new spouse as sole trustee over a trust that benefits both spouse and children creates an inherent conflict. Independent or co-fiduciaries often keep the peace.
Capacity and Undue Influence
Later-life marriages and the documents signed around them draw scrutiny. If a new will, trust amendment, or beneficiary change appears shortly after a marriage, disinherited children sometimes challenge it on grounds of undue influence or lack of capacity. Contemporaneous, attorney-supervised execution, with capacity documented, is the best defense against those claims, and the best way to honor what your parent genuinely wanted.
Common Mistakes That Undo Second-Marriage Plans
- Signing the prenup the night before the wedding. Florida courts can void agreements signed under duress or without adequate time and financial disclosure. Negotiate well in advance.
- Incomplete financial disclosure. A prenup with hidden assets or no exhibit of net worth is vulnerable to being set aside, which collapses every estate waiver inside it.
- Never updating the will after marriage. The pretermitted-spouse statute can hand an unintended share to the new spouse.
- Forgetting beneficiary designations. The will leaves everything to the kids; the old IRA still names the ex-spouse or now names the new spouse by default. Designations win.
- Treating the prenup and estate plan as separate projects. The contradiction between them becomes the lawsuit.
If your parent already has a will or trust, those documents should be reviewed against the marriage and the prenup as a set. Our overview of Florida wills and the basics of Florida probate explain how these instruments interact when an estate is administered, which is exactly the stress test a second-marriage plan needs to survive.
When to Bring In an Attorney
The right time is before the wedding, while both people still have the freedom to negotiate and the goodwill to do it kindly. A coordinated plan drafted then is straightforward. The same plan attempted after a contested death is a contested estate. If your parent is engaged, or recently remarried without updating anything, that is the moment to act.

A second marriage does not have to pit a new spouse against grown children. With a prenuptial agreement and an estate plan built to speak with one voice, your parent can fully provide for the person they love and still keep their promise to the family they built before.
Frequently Asked Questions
Can a prenuptial agreement override Florida's elective share?
Yes, but only if it is done correctly. A surviving spouse in Florida can normally claim an elective share of 30% of the elective estate under Chapter 732, regardless of what the will says. A prenuptial agreement can waive that right, but the waiver must be express and specific. A general clause keeping each spouse’s property separate is usually not enough; the agreement should name the elective share, homestead, family allowance, and exempt property as rights being waived.
Do I need to update my will if I get remarried in Florida?
Almost always. Marriage does not automatically revoke a Florida will, but it can trigger the pretermitted-spouse statute, which may give your new spouse an intestate share as if the will did not address them. Beyond that, spousal rights like the elective share and homestead can override your will entirely. After a remarriage, your will, trust, beneficiary designations, and any prenup should all be reviewed and aligned together.
What happens to the family home in a Florida second marriage?
Florida’s constitutional homestead rules can restrict leaving the primary residence to your children if a spouse survives you. Without a waiver, the surviving spouse may receive a life estate or, by election, a half interest as a tenant in common, which can freeze the children’s inheritance for years. A prenuptial agreement containing an explicit homestead waiver, paired with a deliberate titling and devise strategy, is the usual way to direct the home to the intended heirs.
How does a QTIP trust help in a blended family?
A qualified terminable interest property (QTIP) trust lets you provide income, and often a residence, for your surviving spouse during their lifetime while guaranteeing that the remaining assets pass to your own children when that spouse dies. It is the classic structure for someone who wants to take care of a new spouse without risking that the estate ultimately flows to the spouse’s heirs instead of their children.
Why do the prenup and the estate plan need to be coordinated?
Because when they contradict each other, the contradiction becomes the lawsuit. Prenuptial agreements and estate plans are often drafted years apart by different attorneys using different definitions of separate and marital property. A surviving spouse can argue the later estate plan changed the prenup’s waivers, while the children argue it did not. Drafting both as one coordinated set, with matching definitions and consistent asset references, prevents that fight.
