Second Marriages and Prenuptial Coordination in Florida: An Estate Planning Guide

Planning for a second marriage in Florida means coordinating a prenuptial agreement with your estate plan so that your new spouse and your children from a prior relationship are both provided for, without one inadvertently disinheriting the other. Because Florida law gives a surviving spouse strong automatic rights — an elective share, homestead protection, exempt property, and a family allowance — a remarrying professional or physician cannot rely on a will alone. The prenup and the estate plan must be drafted together, each reinforcing the other.

I have watched too many otherwise careful people treat the prenuptial agreement and the estate plan as separate errands handled by separate lawyers who never speak. The marriage license gets signed, the will gets updated a year later, and nobody checks whether the two documents actually agree. When the first spouse dies, the children and the surviving spouse discover the contradiction in a probate courtroom. This article walks through how to keep that from happening.

Why Second Marriages Demand Tighter Estate Coordination

A first marriage usually involves one shared set of children and one shared pile of assets. A second marriage, especially later in life, almost never does. You arrive with a 401(k) you funded for thirty years, a practice or partnership interest, a house you bought before you met your new spouse, and adult children who quietly assume they are your heirs. Your spouse arrives with their own version of the same.

The friction is structural, not emotional. Florida’s default rules were written to protect a surviving spouse, and they do that aggressively. Left unaddressed, those defaults can route a large share of your separate, pre-marital wealth to a spouse you have known for five years — and away from children you raised for forty. The goal of coordinated planning is not to shortchange anyone. It is to make a deliberate choice instead of letting the statute choose for you.

The Florida Rights Your Will Cannot Override on Its Own

Several spousal protections survive even a clearly worded will. Understanding them is the starting point for any second-marriage plan:

• The elective share. Under Florida Statutes Chapter 732, a surviving spouse may elect to take 30% of the deceased spouse’s “elective estate,” which is a broad pool that reaches well beyond the probate estate — it includes certain trusts, jointly held property, payable-on-death accounts, and assets transferred during the marriage. You cannot simply write your spouse out of your will and expect that to stick.
• Homestead protection. Florida’s constitutional homestead rules restrict how you may devise your primary residence if you are survived by a spouse or minor child. Get this wrong and your spouse may receive a life estate (or, by election, a half interest) in a home you intended to leave outright to your children.
• The family allowance and exempt property. A surviving spouse is entitled to a family allowance (capped by statute) during administration and to certain exempt property, regardless of what the will says.
• The intestate and pretermitted-spouse rules. If you marry after signing your will and never update it, your new spouse may be treated as a “pretermitted spouse” and claim an intestate share as though there were no will at all.

These rights are exactly what a properly drafted prenuptial agreement is allowed to waive. That is the hinge on which the entire plan turns.

What a Florida Prenuptial Agreement Can — and Cannot — Do

Florida adopted a version of the Uniform Premarital Agreement Act, codified at Florida Statutes Chapter 61. Within that framework, spouses may contract about property rights, support, the disposition of property at death, and the making of wills and trusts to carry the agreement out. Critically, a prenup can waive the elective share, homestead rights, the family allowance, exempt property, and intestate succession — but only if the waiver is done correctly.

“Correctly” carries real weight here. Florida courts will enforce a premarital agreement, but they scrutinize how it was made. A waiver of spousal death rights generally requires either fair and reasonable provision for the waiving spouse or full and fair financial disclosure. An agreement signed under duress, without disclosure, or thrust across the table the night before the wedding invites a later challenge. For high-earning professionals and physicians, whose net worth is both substantial and complicated by practice entities and malpractice exposure, that disclosure step is not paperwork — it is the firewall.

The Coordination Failure I See Most Often

Here is the trap. A couple signs a prenup in which each spouse waives all rights in the other’s separate estate. Everyone feels protected. Then, three years later, one spouse drafts a will or revocable trust that — out of affection, or because a generic form prompted it — leaves the surviving spouse a substantial bequest. No one re-reads the prenup. At death, the children argue the gift contradicts the agreement; the spouse argues the will is the later, controlling expression of intent. The estate burns six figures in litigation deciding which document wins.

The fix is simple and almost always skipped: the estate plan must expressly reference the prenuptial agreement, state whether any bequest to the spouse is in addition to or in satisfaction of the agreement’s terms, and confirm the waiver remains intact. One sentence, drafted on purpose, prevents the whole fight.

A Practical Sequence for Coordinating the Two Documents

When a remarrying client comes to me, we do not draft the will first or the prenup first. We map the outcome first, then build both documents toward it. The working sequence looks like this:

1. Inventory separate versus marital property. Identify what each spouse owns coming in, how titling works today, and which assets carry beneficiary designations that override the will entirely.
2. Decide the actual outcome you want. Should the surviving spouse have lifetime use of the home, then it passes to your children? A fixed dollar bequest? Income from a trust but no principal? Name the result before naming the instrument.
3. Draft the prenup to permit that outcome. The agreement should waive the statutory defaults you intend to displace and expressly allow the estate-plan structure you have chosen — for example, permitting a marital trust rather than an outright share.
4. Build the estate plan to deliver it. Typically a revocable living trust to keep details private and avoid probate, paired with a will, and frequently a marital or “QTIP-style” trust that supports the spouse for life while preserving principal for the children.
5. Align beneficiary designations and titling. Retirement accounts, life insurance, and POD/TOD accounts pass outside the will. If they still name an ex-spouse or contradict the plan, the plan is fiction.
6. Re-read everything side by side. The final, non-negotiable step: confirm the prenup, trust, will, and beneficiary forms all describe the same result.

Trust Structures That Solve the Provide-and-Protect Problem

The classic tool for second marriages is a marital trust that gives the surviving spouse a stream of income (and, where appropriate, access to principal for health and support) for life, with the remainder passing to your children when the spouse dies. The spouse is genuinely cared for; the children’s inheritance is not exposed to a future remarriage or a stepchild’s claim. For couples comparing this against other lifetime-interest arrangements, it helps to understand related vehicles such as , which solve a similar “use now, transfer later” problem for real property.

Where a spouse may eventually need long-term care, planning can also intersect with public-benefits tools. A is one such mechanism used in Medicaid planning to shelter surplus income while preserving eligibility; the Florida analysis differs, but the underlying logic — protecting a vulnerable surviving spouse without derailing the children’s remainder — is the same conversation. These cross-jurisdictional comparisons matter for the many Miami professionals who hold property or family ties in both New York and Florida.

Special Considerations for Physicians and Business Owners

Doctors, partners, and practice owners carry estate-planning facts that ordinary forms ignore. A medical practice or professional entity may have a buy-sell agreement dictating what happens to your interest at death — and that agreement can flatly contradict your will if no one harmonizes them. Malpractice and creditor exposure makes Florida’s homestead and certain annuity and life-insurance protections genuinely valuable, but only if titling preserves them. And deferred compensation, pensions, and large qualified accounts are governed by beneficiary forms and, for ERISA plans, by federal spousal-consent rules that a state prenup alone may not satisfy.

For a remarrying physician, that last point is sharp: a prenup waiver of a 401(k) is often ineffective until the spouse signs a separate plan-level waiver after the marriage. I have seen the prenup say one thing and federal law deliver the entire account to the new spouse anyway. Coordination here is not optional polish; it is the difference between your plan working and your plan being a well-organized misunderstanding.

Florida-Specific Pitfalls to Avoid

• Treating the homestead like ordinary property. You cannot freely devise a Florida homestead if you leave a spouse or minor child. Plan the residence deliberately — outright devise to the spouse, a life estate, or a spousal election — never by accident.
• Letting the prenup go stale. Assets, children’s circumstances, and the law all change. A waiver signed twenty years ago should be reviewed, not assumed.
• Skipping disclosure. Inadequate financial disclosure is the most common ground for invalidating a spousal waiver. Document it thoroughly.
• Ignoring non-probate assets. The elective estate reaches trusts, joint accounts, and beneficiary-designated assets. A plan that only addresses the will is incomplete.
• Using a single lawyer for both spouses. Independent counsel for each party strengthens enforceability and reduces the risk of a later “I didn’t understand it” challenge.

The Bottom Line

A second marriage is a fresh start, and Florida law respects it — sometimes more than you intend. The elective share, homestead, and pretermitted-spouse rules will speak loudly for your surviving spouse unless your prenuptial agreement and your estate plan, drafted in tandem, say something more precise. Done well, the two documents let you protect the person you married and the children who came before, with no surprises in probate. Done piecemeal, they become the opening exhibits in a lawsuit. Coordinate them on purpose.

Frequently Asked Questions

Does a Florida prenuptial agreement override a will?

They govern different things and must be coordinated. A prenup can waive a surviving spouse’s statutory rights — like the elective share, homestead protection, family allowance, and intestate succession — under Florida Statutes Chapters 61 and 732. The will then disposes of property consistent with that agreement. If the two contradict each other, the result is often litigation, so the estate plan should expressly reference the prenup and state whether any bequest to the spouse is in addition to or in satisfaction of the agreement.

Can a prenup waive the Florida elective share?

Yes. Florida’s elective share (30% of the elective estate) can be waived in a valid premarital or marital agreement. However, the waiver is only enforceable if it meets the law’s requirements — generally fair and reasonable provision for the waiving spouse or full and fair financial disclosure, signed voluntarily and without duress. Inadequate disclosure is the most common reason a court refuses to enforce the waiver.

What happens to my Florida homestead in a second marriage?

Florida’s constitutional homestead rules limit how you can leave your primary residence if you are survived by a spouse or minor child. Without proper planning, your spouse may receive a life estate (or elect a one-half interest) even if your will leaves the home to your children. The residence should be addressed deliberately — through the prenup, a life estate, an outright devise, or a trust — never left to the default rules.

Will a prenup protect my retirement account from my new spouse?

Not by itself for federal plans. For ERISA-governed accounts like a 401(k), a new spouse generally has rights that require a separate, plan-level spousal waiver signed after the marriage; a prenup alone is often insufficient. IRAs and other beneficiary-designated assets pass by their forms regardless of the will, so all designations must be updated to match your coordinated plan.

Do my spouse and I need separate attorneys for the prenup?

It is strongly advisable. Independent counsel for each party strengthens the agreement’s enforceability and reduces the risk of a later claim that one spouse did not understand or freely agree to the terms. For high-net-worth professionals and physicians with practice interests and complex assets, separate representation is a practical safeguard, not a formality.
