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

Planning for a second marriage in Florida means coordinating two documents that most people treat as unrelated: the prenuptial agreement and the estate plan. A prenup defines what each spouse keeps and waives during marriage and at death, while wills, trusts, and beneficiary designations control where assets actually go. When the two are drafted in isolation, Florida’s spousal-protection statutes—the elective share, homestead, and pretermitted-spouse rules—can override the plan entirely and hand a surviving spouse property the couple intended for children from a prior marriage.

For high-net-worth individuals remarrying in Miami, this is rarely a hypothetical. There are usually adult children, a business interest or two, real estate that may carry homestead protection, and a strong, specific intent about who inherits what. Florida law does not assume that intent. It assumes you want to protect your new spouse, and it will do so unless you affirmatively and correctly say otherwise. Getting the coordination right is the difference between an estate plan that holds and one that unravels in probate court.

Why Florida Treats a New Spouse as a Protected Heir

Florida grants surviving spouses a layered set of rights that exist independent of your will. These are not default rules you can ignore by simply leaving your spouse out of a document. They are statutory entitlements that a surviving spouse can claim against the estate, and several of them survive even a carefully drafted trust.

The four that matter most in second-marriage planning are:

• The elective share. Under Florida Statutes § 732.2065, a surviving spouse may elect to take 30% of the “elective estate,” a broad pool that reaches well beyond the probate estate to include revocable trust assets, certain joint accounts, and pay-on-death designations. You cannot disinherit a Florida spouse simply by funding a trust.
• Homestead. Florida’s constitutional homestead protection restricts how you can devise your primary residence when you are survived by a spouse. Under Fla. Stat. § 732.401, a surviving spouse generally receives a life estate (or may elect a one-half tenancy-in-common interest) in the homestead—regardless of what your will says.
• The pretermitted spouse. If you marry after executing your will and do not update it, Fla. Stat. § 732.301 may treat your new spouse as omitted by accident and award them an intestate share, even though the will predates the marriage.
• Exempt property and family allowance. A surviving spouse is entitled to certain exempt personal property and may petition for a family allowance of up to $18,000 during administration under Fla. Stat. § 732.403.

Each of these can be waived—but only through a valid marital agreement that meets Florida’s specific requirements. That is where the prenup does its real work.

The Prenuptial Agreement Is the Foundation, Not an Afterthought

A prenuptial agreement is the cleanest mechanism to waive spousal estate rights before they ever attach. Florida governs prenups under the Uniform Premarital Agreement Act, codified at Fla. Stat. §§ 61.079, and a properly drafted agreement can waive the elective share, homestead rights, the family allowance, exempt property, and intestate succession. Section 732.702 separately confirms that these rights may be waived by written contract signed in the presence of two subscribing witnesses.

The waiver language has to be explicit. A general statement that each party keeps their “separate property” does not waive the elective share or homestead. Florida courts read these waivers narrowly. If the agreement does not name the right being surrendered, the right survives the agreement.

What a Second-Marriage Prenup Should Address

1. Explicit waiver of each spousal right—elective share, homestead, pretermitted-spouse share, family allowance, and exempt property, each named individually.
2. Affirmative carve-outs. Many couples do not want a full waiver. They want the spouse to receive specific assets—a defined cash bequest, a life estate in the residence, or the income from a trust—while waiving everything else. The prenup should describe those benefits so they reinforce, rather than contradict, the estate plan.
3. Treatment of the marital home. Because homestead rights are constitutional, the residence deserves its own provision: who owns it, whether the survivor gets a life estate or a term of occupancy, and how taxes, insurance, and upkeep are handled.
4. Business and separate-property boundaries. For an owner of a closely held company, the agreement should keep the business and its appreciation outside the marital estate and outside any spousal claim.
5. Full financial disclosure. Florida allows waiver of disclosure, but for high-net-worth couples, attaching complete schedules of assets and liabilities is the single best defense against a later challenge that the agreement was signed without fair knowledge.

Coordinating the Prenup With Wills, Trusts, and Beneficiary Forms

A prenup that waives spousal rights and an estate plan that ignores the new spouse can point in opposite directions. The coordination step is making the estate plan deliver exactly what the prenup promised—no more, no less.

Consider a common Miami fact pattern. A remarrying executive signs a prenup in which the new spouse waives the elective share but is promised a $1 million bequest and a life estate in the condo. If the executive’s revocable trust then leaves “everything to my children” and never funds the spousal bequest, the surviving spouse has a contract claim against the estate and the children inherit into a lawsuit. The documents have to mirror each other.

Tools That Make the Coordination Work

• The QTIP marital trust. A qualified terminable interest property trust pays income to the surviving spouse for life, then passes the remainder to your children. It is the workhorse of blended-family planning: it provides for the spouse, locks the remainder for your bloodline, and can qualify for the federal marital deduction. Strategies that protect a vulnerable surviving spouse—including coordination with long-term-care and benefits planning—are the focus of practices like , and the same trust mechanics apply under Florida law.
• Beneficiary designation audits. Life insurance, IRAs, 401(k)s, and annuities pass outside the will. After remarriage these are the most commonly forgotten documents—and an ex-spouse left on a beneficiary line will generally collect. Florida’s § 732.703 revokes some designations naming a former spouse upon divorce, but it does not cover everything (notably ERISA plans), so every form must be reviewed by hand.
• Homestead-specific drafting. Where the prenup waives homestead, the deed and will should reflect that the survivor takes only the agreed interest. Where it grants a life estate, the documents must create one cleanly to avoid the default split under § 732.401.
• Irrevocable and asset-protection trusts. Assets the couple agrees are off the table can be placed in irrevocable structures during life. For clients also weighing future care costs, vehicles such as a illustrate how an irrevocable trust removes property from both spousal-claim exposure and benefits calculations—though the timing and look-back rules demand early planning.

Asset Protection Layers for High-Net-Worth Blended Families

Beyond inheritance, second-marriage planning for affluent Floridians is also about insulating wealth from creditors, future litigation, and the financial risk that a new marriage statistically carries. Florida is, by design, a strong asset-protection state.

Several Florida features deserve deliberate use:

• Tenancy by the entirety. Property a married couple holds as tenants by the entirety is shielded from the creditors of either spouse individually. In a second marriage, however, entireties ownership can conflict with a plan to keep an asset in your separate column—so the prenup should decide, asset by asset, whether entireties treatment is desired.
• Unlimited homestead protection. Florida’s homestead exemption from creditors is among the most generous in the country, but it interacts with the devise restrictions above. Protection in life and freedom to devise at death are not the same question.
• Statutory protection for retirement accounts and annuities. Florida law shields qualified retirement plans and the cash value of life insurance and annuities from creditors, making them useful vessels for separate wealth.
• Irrevocable trusts for legacy assets. Property meant for children from a prior marriage can be removed from the marital balance sheet entirely, eliminating both the spousal claim and exposure to a future divorce.

None of these layers should be deployed without first reconciling them against the prenup. An asset-protection move that quietly converts separate property into a jointly owned or marital asset can undo the very waiver the couple negotiated. This is precisely the coordination work our handle when structuring plans for remarrying clients.

Common Mistakes That Sink Second-Marriage Plans

• Relying on a will alone. A will does nothing about the elective share, which reaches non-probate assets. Disinheritance by will is an illusion in Florida.
• Vague waiver language. “Each party keeps their own property” does not waive homestead or the elective share. Courts require the right to be named.
• Stale beneficiary forms. The most expensive estate-planning error in remarriage is a retirement account still naming a former spouse or a child who has since predeceased.
• Signing under pressure. A prenup executed days before the wedding without disclosure invites a later claim of duress or unfairness. Build in time and document the process.
• Treating the prenup and estate plan as separate projects. Different lawyers, different files, no reconciliation—and the documents end up contradicting each other. They should be drafted as one coordinated strategy.

When to Bring in a Florida Estate Planning Attorney

If a second marriage involves children from a prior relationship, a business interest, real estate, or assets meaningful enough to fight over, the prenup and estate plan should be built together—ideally before the wedding, and reviewed again after. A focused planning engagement typically covers the marital agreement, an updated will and revocable trust, any marital or asset-protection trusts, a homestead strategy, and a line-by-line beneficiary audit.
