Planning for a second marriage in Florida means coordinating your prenuptial agreement and your estate plan so they say the same thing. A prenup controls what your spouse can claim during the marriage and at divorce; your will, trust, and beneficiary designations control what happens at death. When those documents conflict, Florida’s spousal protection statutes usually win, and your intentions for children from a first marriage can quietly unravel.
For Fort Lauderdale couples remarrying later in life, especially those with significant assets, the stakes are unusually high. You are blending households, balancing children against a new spouse, and often bringing a closely held business, a Broward County home, or a retirement portfolio built over decades into the relationship. The legal tools exist to honor everyone. The mistake is using them in isolation.
Why Florida Treats Second Marriages Differently Than You Expect
Most people assume that what their will says is what happens. In Florida, that assumption is wrong when a surviving spouse is involved. The state has layered several protections into the Florida Statutes that override a will, and these apply equally to a first marriage and a fifth one.
Three statutory rights matter most for second marriages:
- The elective share. Under Florida Statutes Chapter 732, Part II, a surviving spouse may elect to take 30% of the deceased spouse’s “elective estate,” even if the will leaves them nothing. The elective estate is broad. It reaches well beyond the probate estate to include certain trusts, payable-on-death accounts, jointly held property, and assets transferred shortly before death. You cannot disinherit a Florida spouse by simply writing them out of your will.
- Homestead. Florida’s constitutional homestead protection (Article X, Section 4) restricts how you can devise your primary residence when you are survived by a spouse or minor child. If you leave your homestead to anyone other than your spouse outright, the spouse typically receives a life estate, or may elect a one-half tenancy in common interest. This single rule has derailed more second-marriage plans than almost any other.
- Family allowance and exempt property. Sections 732.402 and 732.403 give a surviving spouse a family allowance (up to $18,000) and certain exempt personal property, ahead of other beneficiaries.
Add the spouse’s potential intestate share and pretermitted-spouse rights under Section 732.301 (which can apply when a will predates the marriage), and you have a web of automatic entitlements. For a remarried client who wants to protect children from a prior relationship, every one of these defaults points the wrong direction unless addressed deliberately.
The Prenuptial Agreement: Your First Coordination Tool
A prenuptial agreement is the cleanest way to reshape those defaults before the wedding. Florida adopted the Uniform Premarital Agreement Act in Section 61.079, and it is generous about what spouses may waive. You can contract around alimony, divide property by agreement, and, critically for estate planning, waive the rights at death that would otherwise be automatic.
What a Florida Prenup Can and Cannot Do
A properly drafted Florida prenup can waive the elective share, homestead rights, family allowance, exempt property, intestate share, and the right to serve as personal representative. That is powerful. It lets a spouse say, in advance and in writing, “I will not make a claim against the assets you intend for your children.”
But two limits trip people up. First, a prenup cannot waive child support for minor children. Second, the homestead waiver must be done correctly. Florida courts have repeatedly held that a general waiver of “all marital rights” is not enough to waive homestead devise restrictions; the agreement should reference homestead specifically and clearly. Sloppy drafting here means the spouse keeps a life estate in the house you intended for your kids.
Making the Prenup Enforceable
An unenforceable prenup is worse than none, because it creates false confidence. Florida courts scrutinize these agreements for fairness and disclosure. To survive a challenge:
- Provide full and fair financial disclosure. Each party should exchange a written schedule of assets, debts, and income. Hidden assets are the most common ground for invalidation.
- Sign well before the wedding. An agreement presented the night before the rehearsal dinner invites a duress argument. Give it room to breathe.
- Use separate, independent counsel. Each spouse should have their own attorney. One lawyer cannot represent both sides.
- Avoid unconscionable terms. An agreement that leaves a spouse destitute can be set aside even with disclosure.
If you are entering a second marriage with meaningful wealth, treat the prenup as the foundation document and build the estate plan on top of it, not the other way around.
Coordinating the Prenup With Wills, Trusts, and Beneficiary Designations
Here is where second-marriage planning succeeds or fails. The prenup is a promise about what the spouse will not claim. The estate plan is the mechanism that actually delivers assets to the right people. They have to be drafted as a matched set.
A common failure pattern looks like this: the couple signs a prenup waiving the elective share, then never updates the older estate plan. At death, the will leaves everything to the children, the homestead defaults apply because the deed and devise were never aligned, and a retirement account still names the prior spouse as beneficiary. The prenup did its job, but the surrounding documents did not, and the family ends up in Broward County probate litigation anyway.
The Marital Trust Solution
For most high-net-worth remarried couples, a trust-centered plan is the right answer. A revocable living trust paired with a marital trust (often a QTIP, or qualified terminable interest property trust) lets you do something a prenup alone cannot: provide for your spouse during their lifetime while guaranteeing the remainder passes to your children.
With a QTIP, your surviving spouse receives income (and sometimes principal for health and support) for life. When the spouse dies, the trust assets go to the beneficiaries you named, not the spouse’s relatives or a future spouse. This is the structure that lets a parent honor a new marriage and protect a first family at the same time. It also preserves marital deduction treatment for federal estate tax purposes, which matters for larger estates.
Sophisticated asset-protection planning often layers additional structures on top, and the principles carry across state lines. For clients with northern ties, the same coordination logic drives planning around vehicles like a Medicaid asset protection trust in New York, where long-term care exposure can threaten the inheritance a blended family is counting on.
Don’t Forget the Assets That Skip Probate
Beneficiary designations and titling override your will entirely. In a second marriage, these are the silent saboteurs:
- Retirement accounts (IRAs, 401(k)s). Note that federal ERISA rules require a spouse to consent before a 401(k) names anyone else. A prenup waiver alone may not satisfy ERISA; a post-marriage spousal consent is often required.
- Life insurance. Whoever is named gets paid, regardless of the will.
- Payable-on-death and transfer-on-death accounts. Common, and commonly forgotten.
- Jointly titled real estate. Joint tenancy with right of survivorship passes outside probate and outside your will.
Every one of these must be reviewed and re-papered after a second marriage so the designations match what the prenup and trust intend.
Special Concerns for High-Net-Worth and Asset-Protection-Minded Couples
When the estate is substantial, the coordination problem grows teeth. A few issues recur in our Fort Lauderdale practice.
Keeping Separate Property Separate
Florida is an equitable distribution state, not a community property state, but separate property can become marital through commingling. If you deposit pre-marriage funds into a joint account, or use marital income to improve a separately owned condo, you may convert it. The prenup should define separate property clearly, and your day-to-day account practices should respect those lines. Documentation discipline protects the very assets you went to the trouble of carving out.
Closely Held Businesses
If you own a business, a second marriage introduces succession risk. Coordinate the prenup’s treatment of the business with your operating agreement, buy-sell provisions, and the estate plan so that control passes to the intended successors and not, by default, to a new spouse who never worked in the company.
The Homestead Trap Revisited
Because Florida homestead rules are constitutional, they survive most attempts to plan around them unless the spouse explicitly waives them in the prenup or by a separate deed. If you want your home to go to your children, confirm three things line up: the prenup homestead waiver, the way the property is titled, and the devise in your trust or will. Miss one and the spouse keeps a life estate.
Tax Coordination
For estates approaching the federal exemption, marital deduction planning, portability elections, and QTIP elections need to be sequenced with the prenup’s property division. None of this is fabricated math you can fill in from a template; the figures change, and the elections are made after death by the personal representative. The plan should give your fiduciary the flexibility to make the right call when the time comes.
A Practical Sequence for Remarrying Couples
If you are heading into a second marriage in South Florida, work the problem in this order:
- Negotiate and sign the prenuptial agreement, with full disclosure and independent counsel, well before the wedding.
- Build or update the revocable trust and pour-over will to mirror the prenup’s promises.
- Add a marital or QTIP trust if you need to balance lifetime support for a spouse against a guaranteed inheritance for children.
- Re-paper every beneficiary designation, including 401(k) spousal consents.
- Confirm the homestead waiver, deed, and devise all agree.
- Review the whole package every few years and after any major life or asset change.

The Bottom Line
A second marriage does not have to force a choice between your spouse and your children. Florida law gives you the tools to provide for both, but those tools only work when the prenuptial agreement, the trust, the will, the deed, and every beneficiary form tell the same story. The danger is not malice; it is drift, the slow misalignment of documents signed in different years for different reasons. Coordinate them once, review them periodically, and the plan will hold.

Frequently Asked Questions
Can a prenuptial agreement override Florida's elective share for a surviving spouse?
Yes. Under Florida Statutes Section 61.079 (the Uniform Premarital Agreement Act), a spouse can waive the 30% elective share in a valid prenup. The agreement requires full financial disclosure, independent counsel for each party, and fair, non-unconscionable terms. A general waiver is often not enough to waive homestead rights, so the prenup should reference homestead specifically.
Does my will control what my new spouse inherits in Florida?
Not entirely. Florida grants a surviving spouse automatic rights that override a will, including the elective share, constitutional homestead protection, family allowance, and exempt property. A retirement account, life insurance policy, or jointly titled home also passes outside your will by beneficiary designation or titling. All of these must be coordinated with your estate plan, not just your will.
How do I protect children from a first marriage while still providing for my new spouse?
A marital or QTIP trust is the usual solution. It pays income (and sometimes principal) to your surviving spouse for life, then passes the remaining assets to the children you named, rather than to the spouse’s heirs or a future spouse. This lets you support a new marriage and guarantee a first family’s inheritance at the same time, while preserving the federal marital deduction.
What is the homestead trap in Florida second-marriage planning?
Florida’s constitutional homestead rules restrict how you can leave your primary residence when survived by a spouse. If you devise the home to your children, the spouse typically receives a life estate (or may elect a one-half interest) unless they waived homestead rights in the prenup or by deed. The waiver, the property’s title, and the devise in your will or trust must all align, or your children may not receive the home outright.
When should we sign the prenup relative to the wedding?
As early as possible. Signing well before the wedding strengthens enforceability by removing any argument of duress or coercion. An agreement presented days before the ceremony is far easier to challenge. Build in time for full financial disclosure and review by each party’s separate attorney.
