Planning for Second Marriages and Prenuptial Coordination in Florida

Planning for a second marriage in Florida means coordinating your estate plan and your prenuptial agreement so that remarriage does not accidentally disinherit your children, override your existing trusts, or trigger Florida’s spousal protection laws in ways you never intended. In practice, that requires a prenuptial agreement, updated beneficiary designations, and revised wills or trusts that all say the same thing. When those documents disagree, Florida law generally fills the gaps in favor of the surviving spouse, which is exactly the outcome most blended families are trying to avoid.

For the snowbirds and seasonal residents who make Palm Beach their home for part or all of the year, this is one of the most common planning blind spots I see. You may have spent decades building an estate plan tailored to your first family. Then you remarry, change nothing, and assume your old documents still control. They often do not.

Why a Second Marriage Rewrites Your Florida Estate Plan Automatically

Remarriage is not a neutral event in estate planning. The moment you say “I do” again, Florida law grants your new spouse a bundle of rights that can quietly reshuffle where your property goes. These rights attach by operation of law, whether or not you update a single document.

Three Florida protections matter most for second marriages:

• The elective share. Under Florida Statutes Chapter 732, Part II, a surviving spouse may claim an elective share equal to 30 percent of the deceased spouse’s “elective estate.” That estate is broad. It reaches well beyond the probate estate to include certain trusts, jointly held property, and pay-on-death accounts. You cannot fully disinherit a spouse in Florida by will alone.
• Homestead protections. Florida’s constitutional homestead rules (Article X, Section 4) restrict how you can leave your primary residence if you are survived by a spouse or minor child. If you are married and try to leave the homestead to anyone other than your spouse, the devise can be invalid, and the surviving spouse typically receives a life estate or, by election, a one-half tenancy in common interest under Florida Statutes Section 732.401.
• The pretermitted spouse and family allowances. If you marry after signing your will and the will does not provide for the new spouse, Florida Statutes Section 732.301 may treat that spouse as “pretermitted” and award an intestate share. Separate spousal and family allowances under Sections 732.402 and 732.403 can also come off the top of the estate.

Stack these together and the picture is clear. A new spouse can be constitutionally and statutorily entitled to a meaningful slice of your estate, your house included, even if your will leaves everything to your children from a prior marriage. A prenuptial agreement is the primary lawful tool for adjusting these defaults before they ever apply.

What a Prenuptial Agreement Can and Cannot Do in Florida

Florida adopted the Uniform Premarital Agreement Act, codified at Florida Statutes Chapter 61, Part II. Under that framework, couples have wide latitude to define their own financial terms. A well-drafted prenup can waive the elective share, waive homestead rights, waive the pretermitted spouse share, and waive the spousal and family allowances. It can also clarify what counts as separate property versus marital property and what each spouse will receive at death.

Rights Commonly Waived in a Second-Marriage Prenup

1. The 30 percent elective share against the elective estate.
2. Homestead inheritance rights, allowing you to devise your residence to your children or a trust.
3. The intestate or pretermitted share that would otherwise pass to a spouse not named in the will.
4. Spousal and family allowances and exempt property rights.
5. Rights in specific retirement accounts, though these need separate handling, as discussed below.

The Hard Limits Florida Courts Enforce

A prenup is not bulletproof. Florida courts will set one aside if it was not signed voluntarily, or if it was unconscionable when executed and the challenging spouse did not receive fair disclosure of assets, did not waive disclosure, and could not reasonably have known the other’s finances. The lesson from decades of Florida case law is consistent: full, written financial disclosure and independent counsel for each spouse are the strongest protections against a later challenge. Two attorneys, two schedules of assets, and breathing room before the wedding are worth far more than a discount on legal fees.

One important nuance for estate planning specifically: a general waiver of “all rights” in a spouse’s property does not always waive the right to be named as a beneficiary on a retirement plan. The Florida Supreme Court addressed related questions in Friedberg v. Sunbank and later cases, and federal law adds another layer.

Coordinating Beneficiary Designations and ERISA Accounts

Here is where second-marriage plans most often unravel. Your 401(k), pension, and other employer retirement plans are governed by ERISA, a federal law. Under ERISA, a surviving spouse generally has an automatic right to the account unless the spouse consents in writing to a different beneficiary after the marriage. A prenuptial agreement signed before the wedding does not satisfy that federal spousal consent requirement, because at the time of signing there is no spouse yet.

The practical fix is a two-step process:

• Sign the prenup before marriage to handle state-law rights and to obligate your spouse to cooperate.
• After the wedding, have your spouse sign a separate, plan-specific spousal waiver and consent form so the retirement plan beneficiary designation actually holds up.

IRAs are treated differently from ERISA plans and follow the contract and Florida law, but the safest approach is to review every account and align each beneficiary designation with the prenup and the will. Beneficiary designations override your will. A stale designation naming an ex-spouse or naming your new spouse contrary to your agreement will control the money regardless of what your will says. This coordination work is the heart of competent .

Trusts: The Workhorse of Blended-Family Planning

For most remarried couples in Palm Beach, the cleanest way to provide for a surviving spouse while protecting children from a prior marriage is a trust rather than an outright bequest. Two structures do the heavy lifting.

The QTIP Trust

A Qualified Terminable Interest Property trust, or QTIP, lets you support your surviving spouse for life while guaranteeing that whatever remains passes to your own children when that spouse dies. The spouse receives all income from the trust, and often access to principal for health and support, but cannot redirect the remainder. It is the classic answer to the second-marriage worry: “I want my husband cared for, but I do not want my estate ending up with his children instead of mine.” A QTIP can also qualify for the unlimited marital deduction, deferring federal estate tax until the second death.

Revocable Living Trusts and Lifetime Planning

A revocable living trust keeps assets out of probate, maintains privacy, and lets you spell out precisely how a surviving spouse and your children are provided for. For older couples thinking about long-term care, asset protection planning deserves a seat at the table early. Strategies such as a can shield assets from future nursing-home costs, though the five-year lookback means this planning must start years before care is needed. Couples who split time between Florida and the Northeast should be especially careful, because each state runs its own Medicaid program with different rules.

The Snowbird Angle: Domicile, Two States, and One Plan

Seasonal residents face an extra wrinkle. If you winter in Palm Beach but keep a home and ties up north, the question of which state is your legal domicile affects estate taxes, creditor protection, and which homestead and spousal rules apply. Florida’s lack of a state income tax and its strong homestead creditor protections make Florida domicile attractive, but you have to actually establish it: file a Declaration of Domicile, register to vote, get a Florida driver’s license, and treat Florida as home in fact, not just on paper.

A prenup and estate plan drafted in another state will not automatically account for Florida’s elective share or homestead rules. If you have remarried and relocated, both documents deserve a Florida review. Families navigating multi-state care issues and aging parents often benefit from coordinated that understands how the two jurisdictions interact.

A Practical Coordination Checklist

• Sign the prenuptial agreement well before the wedding, each spouse with independent counsel and full asset disclosure.
• After marriage, execute plan-specific spousal waivers for every ERISA retirement account.
• Update or restate your will and any trusts so they match the prenup, including specific homestead language.
• Re-check every beneficiary designation: life insurance, IRAs, 401(k)s, annuities, and transfer-on-death accounts.
• Confirm titling of the homestead and any jointly held property.
• Establish and document Florida domicile if you intend Florida law to govern.
• Revisit the plan after any major change, and at minimum every few years.

Done right, none of this has to feel adversarial. The goal is a plan where everyone, your spouse and your children alike, knows what to expect and why. That clarity is the real gift of coordinated planning. When disputes do arise after death, the cost and friction of Florida probate litigation can dwarf what careful drafting would have cost. If you are entering a second marriage or have already remarried without updating your documents, this is the moment to get them aligned.

Frequently Asked Questions

Can a prenuptial agreement waive my spouse's right to my house under Florida homestead law?

Yes. Florida’s constitutional homestead protections restrict leaving your primary residence to anyone but your spouse, but a properly drafted prenuptial agreement under Florida Statutes Chapter 61 can include a clear, knowing waiver of homestead inheritance rights. The waiver should be explicit, signed with full financial disclosure, and ideally with each spouse represented by separate counsel so it survives a later challenge.

Does a Florida prenup automatically protect my 401(k) for my children?

Not by itself. Employer retirement plans like 401(k)s and pensions are governed by federal ERISA law, which gives a surviving spouse an automatic right to the account unless the spouse signs a plan-specific waiver after the marriage. A prenup signed before the wedding cannot satisfy that requirement because there is no spouse yet. You need a separate post-marriage spousal consent form for each ERISA account.

What is the elective share and can I avoid it in a second marriage?

Under Florida Statutes Chapter 732, a surviving spouse can claim an elective share equal to 30 percent of the deceased spouse’s elective estate, which includes much more than just probate assets. You cannot fully disinherit a Florida spouse by will alone, but the elective share can be waived in a valid prenuptial or postnuptial agreement, which is why couples in second marriages commonly include that waiver.

Should snowbirds who split time between Florida and another state have their estate plan reviewed?

Yes. Domicile determines which state’s elective share, homestead, estate tax, and Medicaid rules apply to you. A plan drafted in a northern state will not account for Florida’s protections, and an unclear domicile can expose you to taxes or creditor claims in two places. Establishing and documenting Florida domicile, then aligning your prenup and estate plan with Florida law, prevents costly surprises.

What is a QTIP trust and why is it useful for blended families?

A Qualified Terminable Interest Property (QTIP) trust provides income, and often limited principal, to a surviving spouse for life, then passes the remaining assets to the beneficiaries you choose, typically your own children. It lets you care for a new spouse without risking that your estate ultimately goes to that spouse’s heirs instead of yours, and it can qualify for the marital deduction to defer federal estate tax.
