Planning for a second marriage in Florida means coordinating your estate plan with a marital agreement so your new spouse and your children from a prior relationship are both protected, instead of pitted against each other after you die. Florida’s homestead rules and the spousal elective share can override the wishes in your will, so a prenuptial or postnuptial agreement is usually the only reliable way to control how your assets pass. Done right, the prenup and the estate plan are written to match each other; done carelessly, they contradict each other and trigger litigation.
I have sat across the table from too many blended families who learned this the hard way. A widower remarries at 62, signs a new will leaving the house to his adult kids, and assumes that settles it. He passes, and his second wife exercises rights she never knew she had under Florida law. The kids are stunned. The wife feels accused of greed. Nobody did anything wrong, exactly, but nobody coordinated the documents, and the family pays for it in probate court. This article walks through how to avoid that.
Why second marriages change Florida estate planning
A first marriage and a second marriage are not the same planning problem. In a long first marriage, spouses usually want everything to flow to the survivor and then to their shared children. The interests line up. In a second marriage, they often diverge: you may want your current spouse cared for during their lifetime, but you also want your children from your first marriage to ultimately inherit the home you owned before you ever met your new spouse.
Florida law does not automatically honor that intent. The state gives surviving spouses statutory rights that exist independent of your will. If you do not plan around them deliberately, those rights control. The three that matter most are the homestead protection, the elective share, and the family allowance and exempt property rules. Each one can quietly redirect assets you assumed were already spoken for.
The homestead trap that surprises real estate-minded owners
If you own a Florida home and you are married, you cannot freely devise that homestead by will. This is the single most misunderstood rule in Florida estate planning, and it bites homestead-focused owners the hardest. Under Article X, Section 4 of the Florida Constitution and Florida Statutes § 732.401, if you are survived by a spouse and you own homestead property, your will cannot simply leave the house to your children.
Instead, the default outcome is that your surviving spouse receives a life estate in the homestead, with the remainder passing to your descendants. Since 2010, Section 732.401 also lets the surviving spouse elect, within six months of death, to take an undivided one-half tenant-in-common interest instead of the life estate. Either way, your children do not get clean title, and your spouse does not get full ownership. Everyone gets a fraction, and fractions among in-laws breed disputes.
The practical consequences are real. A life-estate spouse is responsible for taxes, insurance, and ordinary upkeep but may resist selling. The remainder children cannot sell or refinance without the spouse’s cooperation. If the spouse moves into assisted living, the house can sit in limbo. For owners whose net worth is concentrated in real estate, this is the central problem a second-marriage plan has to solve.
The elective share: 30% your spouse can claim
Florida’s elective share, governed by Florida Statutes §§ 732.201 through 732.2155, entitles a surviving spouse to thirty percent of the deceased spouse’s “elective estate.” Critically, the elective estate is broad. It reaches beyond the probate estate to capture assets people often assume are off-limits: revocable trust assets, certain pay-on-death and transfer-on-death accounts, joint accounts, and even some property transferred within a year of death.
You cannot defeat the elective share by simply leaving your spouse out of your will or by funneling assets into a revocable living trust. The statute was written specifically to close those loopholes. So a second spouse who feels shortchanged by the estate plan can file for the elective share within the statutory deadline and claw back nearly a third of a carefully assembled estate. The only clean, dependable way to alter that entitlement is a valid marital agreement in which the spouse knowingly waives it.
How a prenuptial agreement coordinates with the estate plan
This is where prenuptial coordination earns its keep. A prenuptial agreement, governed in Florida by the Uniform Premarital Agreement Act, Florida Statutes §§ 61.079, lets prospective spouses contract around the default rules. In an estate-planning context, the prenup is doing two jobs at once: it addresses what happens at divorce, and just as importantly, it addresses what happens at death.
A well-drafted second-marriage prenup typically includes express waivers of the rights that would otherwise scramble your plan. Those waivers commonly cover:
- The elective share under Chapter 732, so your spouse cannot claim the statutory 30% against your estate.
- Homestead devise restrictions, so you can leave the house to your children outright (this waiver has specific formalities and is worth getting exactly right).
- The family allowance and exempt property under §§ 732.402 and 732.403.
- Intestate share and pretermitted spouse rights, in case a will is ever missing or out of date.
- The right to serve as personal representative, if you want a neutral or family fiduciary instead.
What the prenup waives, the estate plan must then provide for affirmatively. If your spouse gives up the elective share and homestead rights, the plan should say clearly what your spouse does receive instead. Often that is a life estate the couple actually wants, a defined cash bequest, a qualified terminable interest property (QTIP) trust, or the right to live in the home for a set period. Coordination means the giving-up and the giving-back are written into matching documents that reference each other.
Making the waiver enforceable: full disclosure matters
A prenup is only as strong as its enforceability. Florida courts will set aside premarital agreements that were signed without fair financial disclosure, signed under duress, or otherwise unconscionable. The leading principles trace back to Florida case law such as Casto v. Casto and are now partly codified in § 61.079.
To survive a challenge years later, each spouse should have independent legal counsel, exchange a complete written schedule of assets and income, and sign well before the wedding rather than the night before. A waiver of death-time rights, in particular, must be a knowing and voluntary relinquishment. Rushed, one-sided agreements are exactly the ones that get thrown out, which then re-exposes the estate to the elective share you thought you had handled.
Tools that protect both your spouse and your children
Once the prenup clears the statutory rights out of the way, the estate plan can do its real work: caring for your spouse without disinheriting your kids. Several structures do this well, and the right one depends on the size and shape of your estate.
- QTIP trust. A qualified terminable interest property trust pays income to your surviving spouse for life, then passes the remaining principal to your children. Your spouse is provided for; your children are guaranteed what is left. This is the workhorse of second-marriage planning.
- Revocable living trust with a marital sub-trust. A funded revocable trust avoids probate and can carve out a defined share for the spouse while directing the balance to descendants, all without a public court fight.
- Life estate by design. Sometimes the constitutional life-estate outcome is actually fine; you simply formalize it with clear terms on who pays taxes and insurance and what happens if the spouse moves out.
- Life insurance as an equalizer. If the house goes to the children, a life insurance policy naming the spouse can provide liquidity so no one waits on a sale.
- Beneficiary designations that match the plan. Retirement accounts and POD accounts pass by designation, not by will, so they must be reviewed and aligned, or they will quietly contradict everything else.
For families with elder-care exposure, longer-term asset protection planning can layer on top of these tools. Strategies built around irrevocable trusts, such as a , can shield a home and other assets from long-term care costs while still preserving an inheritance for children. For a disabled spouse or beneficiary who needs to keep public benefits intact, a can hold surplus income without disqualifying them. These approaches require careful drafting and counsel licensed where you live, but they show how a second-marriage plan can stretch to cover real-life contingencies.
Common mistakes blended families make in Florida
After years of cleaning up these situations, the same errors recur. The first is assuming a will is enough. It is not, because homestead and elective-share rules override the will. The second is signing a prenup that addresses divorce but stays silent on death; that prenup does nothing for your estate plan. The third is updating one document and forgetting the others, so the trust, the deed, and the beneficiary forms all tell different stories.
The fourth mistake is naming the new spouse and an adult child as co-fiduciaries in the hope that “they’ll work it out.” They usually do not. Co-trustees from different sides of a blended family tend to deadlock, and the deadlock lands in court. A professional or neutral fiduciary is often cheaper than the litigation it prevents.

Timing: coordinate before the wedding, revisit after
The cleanest sequence is to negotiate the prenup first, then build the estate plan to honor it, all before the marriage. After the wedding, the same goals can still be reached with a postnuptial agreement, though postnups face their own scrutiny and can be harder to negotiate once vows are exchanged. Either way, plan to revisit the documents after major events: a home purchase, a sale, a serious illness, the birth of grandchildren, or a move to a new county.
Bringing it together with the right counsel
Second-marriage planning is not a form you fill out. It is a coordination exercise across family law and estate law, with Florida’s homestead and elective-share statutes setting the boundaries you have to respect. The goal is a set of documents that agree with each other: a prenup that knowingly waives the right rights, an estate plan that provides for your spouse in the way you both actually intend, and titling and beneficiary designations that match. When those pieces line up, your spouse is cared for, your children inherit what you meant them to, and your family stays out of court.
If you are entering a second marriage in South Florida, it is worth sitting down with an attorney who handles both the marital agreement and the estate plan, so the two are built to work together rather than against each other.

Frequently Asked Questions
Can a prenuptial agreement override Florida's homestead and elective share rules?
Yes, but only if it is drafted carefully. Florida law allows spouses to waive the elective share, homestead devise restrictions, family allowance, and other death-time rights in a valid premarital agreement under Florida Statutes Chapter 61 and Chapter 732. The waiver must be knowing and voluntary, supported by full financial disclosure, and ideally negotiated with independent counsel for each spouse, or a court may set it aside.
What happens to my Florida home if I remarry and leave it to my children in my will?
Under Article X, Section 4 of the Florida Constitution and Florida Statutes 732.401, your will generally cannot devise homestead property freely if you have a surviving spouse. By default your spouse receives a life estate with the remainder to your descendants, or your spouse may elect a one-half tenant-in-common interest. To leave the home outright to your children, your spouse must validly waive homestead rights, usually in a prenuptial agreement.
How much can my surviving spouse claim under Florida's elective share?
Florida’s elective share entitles a surviving spouse to 30% of the elective estate under Florida Statutes 732.2065. The elective estate is broad and includes revocable trust assets, certain joint and pay-on-death accounts, and some transfers made before death, so it cannot be defeated simply by using a trust or omitting the spouse from a will. A valid marital agreement waiving the elective share is the dependable way to change this.
What is a QTIP trust and why is it useful in second marriages?
A QTIP, or qualified terminable interest property trust, pays income to your surviving spouse for life and then passes the remaining principal to beneficiaries you choose, typically children from a prior marriage. It lets you provide for your current spouse without giving up control over who ultimately inherits, which makes it one of the most common and effective tools in blended-family estate planning.
Should I get a prenup or a postnup for second-marriage estate planning?
A prenuptial agreement signed well before the wedding is the cleaner option because it can be coordinated with your estate plan in advance and faces fewer enforceability hurdles. A postnuptial agreement can accomplish similar goals after marriage but is often harder to negotiate and may receive closer judicial scrutiny. In either case, the agreement should address death-time rights, not just divorce, to support your estate plan.
