Planning for a second marriage in Florida means deliberately coordinating a prenuptial agreement with your estate plan so that a new spouse and children from a prior relationship are each protected without colliding. In Florida, marriage automatically rewrites parts of your inheritance picture through the spousal elective share, homestead protections, and intestacy rules, and a properly drafted prenup is the primary tool for adjusting those defaults by agreement before the wedding. Done right, the prenup and the will or trust speak with one voice; done carelessly, they contradict each other and end up litigated.
If you are an adult child helping an aging parent remarry, or a parent remarrying later in life, this is the area where good intentions most often unravel. The law presumes a surviving spouse should inherit generously. That presumption is sensible for a forty-year marriage. It is frequently a poor fit for a couple who marry in their sixties or seventies, each with grown children, separate homes, and decades of separately accumulated assets.
Why Florida’s default rules surprise second-marriage couples
Florida gives a surviving spouse rights that override what an outdated will might say. Three of them matter most.
The elective share. Under Florida Statutes § 732.2065, a surviving spouse may claim an elective share equal to 30% of the deceased spouse’s “elective estate.” That elective estate is broad. It is not just the probate assets; it reaches certain trusts, jointly held property, pay-on-death accounts, and assets transferred during the marriage. A parent who carefully left everything to his children in a will can still see a new spouse claim nearly a third of the combined estate, because the elective share is a statutory right, not a gift the will controls.
Homestead. Florida’s constitutional homestead protection (Article X, Section 4) restricts how a married person can leave the primary residence. If a person is survived by a spouse, the homestead cannot simply be willed to the children. Absent a valid waiver, the surviving spouse receives at minimum a life estate (or, by election under § 732.401, a one-half tenancy in common), with the remainder to the descendants. That can trap a family in a co-ownership nobody wanted.
Pretermitted spouse and intestacy. If your will predates the marriage and does not contemplate the new spouse, § 732.301 may treat that spouse as “pretermitted” and award an intestate share as though there were no will at all. And if there is no will, § 732.102 splits the estate between the spouse and the descendants from another relationship.
None of these defaults are wrong. They simply assume a different family than the one in front of you. The prenuptial agreement is how Florida lets a couple opt into a structure that fits their actual lives.
What a Florida prenuptial agreement can and cannot do
Florida adopted the Uniform Premarital Agreement Act, codified at § 732.702 and Chapter 61. Within that framework, a prenup can do a great deal of estate-planning work:
- Waive or limit the elective share for each spouse, so each person’s separate assets pass to their own children.
- Waive homestead rights in the other spouse’s residence, freeing each owner to leave the home to descendants. The waiver language must be specific; a general waiver of “all marital rights” has been held insufficient to waive homestead in some cases, so this clause deserves precise drafting.
- Waive intestate and pretermitted-spouse rights, family allowance, exempt property, and the right to serve as personal representative.
- Define separate versus marital property, including how appreciation, income, and commingled accounts will be treated.
- Affirmatively provide for the new spouse—a prenup is not only a shield. Many couples use it to guarantee the survivor a set sum, a life estate in the home, or a stream of income, while steering the remainder to children.
There are limits. A premarital agreement cannot adversely affect a child’s right to support. It cannot be used to defraud existing creditors. And while it can waive a spouse’s rights, it cannot, by itself, transfer the assets—that is the job of the will, trust, deed, and beneficiary designations that follow. The prenup sets the rules; your estate plan executes them.
The two failure modes that produce litigation
I see the same two breakdowns repeatedly. The first is a prenup that waives the elective share but an estate plan that was never updated to match—so the documents still leave assets to the spouse who supposedly waived them, creating ambiguity about intent. The second is the opposite: a beautifully drafted will and trust giving everything to the children, with no prenup, so the surviving spouse simply exercises the elective share and homestead rights the law guarantees. Coordination is the whole game.
How to make a Florida prenup survive a challenge
An unenforceable prenup is worse than none, because the family relied on it. Florida courts will set aside a premarital agreement that was not voluntary, or that was unconscionable when signed without fair disclosure. To withstand scrutiny:
- Disclose assets fully and in writing. Attach schedules listing each party’s property, debts, and approximate values. The most common ground for invalidation is hidden or vague disclosure.
- Use separate, independent attorneys. One lawyer cannot ethically represent both fiancés. Independent counsel for each side is the strongest evidence of voluntariness.
- Sign well before the wedding. An agreement presented days before guests arrive invites a duress argument. Build in weeks, not hours.
- Avoid lopsided, punitive terms. An agreement that leaves a long-married survivor destitute is vulnerable. Provisions that are fair and provide something for the survivor hold up better.
- Re-confirm at execution time. Have each party acknowledge they read it, understood it, and signed freely.
For an aging parent, add one more layer: capacity and undue influence. If the parent has any cognitive decline, document capacity at signing—ideally with a contemporaneous physician note—so adult children on the other side cannot later argue the new spouse pressured a vulnerable person into signing. The same caution protects against the reverse accusation, that the children pressured the parent.
Coordinating the prenup with the rest of the estate plan
The prenup is one instrument in an orchestra. After it is signed, every other document has to be tuned to it.
Revocable living trust as the workhorse
For second marriages, a revocable trust usually does the heavy lifting better than a will alone, because it avoids probate, keeps the arrangement private, and can hold assets in a structure that pays the surviving spouse during life while preserving principal for the children. A common pattern is a QTIP-style marital trust: the survivor receives income (and sometimes limited principal) for life, and on the survivor’s death the remainder passes to the first spouse’s children—not to the survivor’s own heirs. This is the classic answer to the fear that “everything I leave my spouse will eventually go to her kids instead of mine.”
Beneficiary designations and titling
Retirement accounts, life insurance, and pay-on-death accounts pass outside the will entirely. A prenup that waives spousal rights does nothing if the IRA still names the prior spouse—or if it now reflexively names the new spouse against the plan. Review every designation. Note too that under federal ERISA rules, a spouse’s waiver of certain qualified-plan benefits generally must be signed after the marriage, so a prenup alone may not cover a 401(k). Coordinate the prenup with a post-marriage spousal consent where required.
Homestead deed planning
If the prenup waives homestead, the next step is deciding what actually happens to the home: leave it to the children outright, grant the survivor a life estate, or give the survivor the right to remain for a fixed period. Each requires precise deed and document language so the waiver is honored and the title transfers cleanly.
Cross-state coordination for snowbirds
Many Long Island families spend winters in Florida, and a parent’s remarriage may straddle both states. Domicile drives which state’s spousal-rights law governs the estate, and the rules differ—New York, for example, uses an elective share framework under EPTL 5-1.1-A rather than Florida’s. If your parent owns a home in New York and another in Florida, the planning must account for both jurisdictions and for ancillary probate. Tools that work in one state, including Medicaid-focused trusts, need state-specific drafting; our colleagues describe how a Medicaid Asset Protection Trust in New York is structured, which is a useful comparison when a parent has long-term-care exposure on both sides of the coast. For a parent with a disability or who is already receiving needs-based benefits, a pooled income trust may preserve eligibility in ways a prenup cannot. The Florida side of the plan—wills, trusts, homestead deeds—should be handled by counsel admitted there; you can review the scope of Florida estate planning services to see how the two states’ documents fit together.
A practical sequence for families
When an aging parent tells you they are remarrying, resist the urge to react emotionally and instead work the process in order:
- Have a candid family conversation about goals—protect the survivor, protect the children, protect the home.
- Engage independent counsel for each fiancé and begin asset disclosure early.
- Negotiate and sign the prenup with elective-share, homestead, and intestacy waivers tailored to the plan.
- Rebuild the wills and trust to match the prenup, including any marital trust for the survivor.
- Update deeds, beneficiary designations, and obtain spousal consents where federal law requires.
- Document capacity and store the originals where the family and personal representative can find them.
Handled in this order, a second marriage becomes a source of security rather than a future probate fight. For related groundwork, see our overview of wills and trusts and what to expect from Florida probate, and reach out through our contact page when you are ready to coordinate the pieces.
The bottom line
Florida’s spousal-protection laws are powerful and they activate the moment the couple says “I do.” A prenuptial agreement is the lever that lets a remarrying couple reset those defaults—but only if the will, trust, deeds, and beneficiary forms are then aligned with it. The agreement and the estate plan are not two separate projects. They are one plan, drafted together, that lets a parent honor a new spouse and protect the children at the same time.
Frequently Asked Questions
Can a Florida prenuptial agreement waive the spousal elective share?
Yes. Under Florida Statutes section 732.702, spouses can waive the 30% elective share (and homestead, intestate, and family-allowance rights) in a premarital agreement, provided there was fair and reasonable disclosure of assets and the agreement was signed voluntarily. The waiver language should be specific, and each party should ideally use independent counsel.
Does a prenup automatically protect my children from a prior marriage?
No. A prenup sets the rules but does not transfer assets by itself. After signing, you must update your will or trust, deeds, and beneficiary designations to actually direct property to your children. A common structure is a marital (QTIP-style) trust that supports the new spouse for life and then passes the remainder to your children.
How does Florida homestead affect a second marriage?
Florida’s constitutional homestead protection restricts leaving the primary residence to anyone other than a surviving spouse and minor children. Absent a valid, specific waiver, a surviving spouse receives at least a life estate (or can elect a one-half tenancy in common). A prenup can waive homestead rights, but the language must be precise and paired with proper deed planning.
My parent owns homes in both New York and Florida. Which state's spousal laws apply?
It depends largely on domicile, and each state has its own spousal-rights regime—Florida’s elective share differs from New York’s under EPTL 5-1.1-A. Real property is generally governed by the law of the state where it sits, so a New York home and a Florida home may require coordinated planning and possibly ancillary probate. Use counsel admitted in each state.
What makes a Florida prenuptial agreement unenforceable?
Courts may set aside a prenup that was signed involuntarily or that was unconscionable when executed without fair, written disclosure of assets. Hidden assets, signing under time pressure right before the wedding, lack of independent counsel, and, for an aging signer, questions of capacity or undue influence are the most common grounds for a successful challenge.
