Getting engaged is a time for planning a wedding, merging households, and imagining a shared future. For a growing number of couples, it is also a time to have an honest conversation about money, property, and what would happen if the marriage did not last. In Florida, that conversation is shaped by a specific statute: the Uniform Premarital Agreement Act, codified at section 61.079 of the Florida Statutes.
The statute sets the rules for what a prenuptial agreement can include, how it must be signed, and when a court will refuse to enforce it. Couples who understand these rules before they sit down with an attorney tend to have smoother negotiations and end up with agreements that hold up if they are ever tested. Couples who rely on templates, assumptions, or advice from friends often discover too late that key provisions are unenforceable.
Below is a plain-English breakdown of what Florida’s premarital agreement law allows, what it prohibits, and what engaged couples in Tampa should keep in mind as they prepare to sign.
What Is Florida’s Uniform Premarital Agreement Act?
The Uniform Premarital Agreement Act is a model law originally drafted by the Uniform Law Commission to bring consistency to how states treat prenuptial agreements. Florida adopted its version of the act in 2007, and it applies to premarital agreements signed on or after October 1, 2007.
Before the act, Florida prenups were governed almost entirely by case law. Courts relied on decisions such as Casto v. Casto, a 1987 Florida Supreme Court case that set out the circumstances under which a prenup could be set aside. Those earlier standards still matter for agreements signed before the statute took effect, but for couples marrying today, section 61.079 is the controlling framework.
The act does several things at once. It defines what a premarital agreement is, sets minimum formalities for signing, lists the subjects couples may address, carves out the matters they cannot, and establishes the specific grounds a spouse must prove to invalidate an agreement. It also addresses amendments, revocations, and what happens if a marriage turns out to be void.
For engaged couples, the practical takeaway is that Florida law generally favors enforcing prenuptial agreements. Courts treat them as contracts, and a well-drafted agreement signed under fair circumstances is likely to be upheld. That deference is exactly why getting the process right matters so much.
How Does Florida Define a Premarital Agreement?
Under section 61.079, a premarital agreement is an agreement between prospective spouses made in contemplation of marriage and effective upon marriage. Two parts of that definition deserve attention.
First, the agreement must be made in contemplation of marriage. It is signed before the wedding by two people who intend to marry each other. An agreement signed after the wedding is a postnuptial agreement, which Florida courts also enforce, but under a somewhat different framework that has developed largely through case law.
Second, the agreement does not become effective until the marriage takes place. If the engagement ends, the agreement has no legal effect. Couples sometimes worry that signing a prenup creates obligations immediately, but under Florida law nothing in the agreement operates until the parties are actually married.
The statute also defines “property” broadly. It includes any interest, present or future, legal or equitable, vested or contingent, in real or personal property, including income and earnings. That means a prenup can address not only the house and bank accounts each person owns today, but also future salary, business growth, stock options, retirement contributions, inheritances, and assets neither party has acquired yet.
What Formal Requirements Must a Florida Prenup Meet?
Florida’s formal requirements are fairly simple. A premarital agreement must be in writing and signed by both parties. The statute also states that the agreement is enforceable without consideration. In ordinary contract law, each side generally has to give something of value for a contract to be binding. The act removes that hurdle, so a prenup does not fail simply because one spouse appears to receive more than the other.
Although the statute itself does not require notarization or witnesses for the agreement as a whole, those formalities become important if the agreement waives rights at death. Florida’s probate code, discussed later in this article, requires two subscribing witnesses for a valid waiver of certain spousal inheritance rights. Because most comprehensive prenups address both divorce and death, experienced attorneys typically have agreements signed in front of two witnesses and a notary as a matter of course.
Oral agreements are not enforceable as premarital agreements in Florida. A promise made over dinner, a text message exchange, or an unsigned draft circulated by email will not satisfy the statute. If a provision matters to either person, it needs to be in the final signed document.
What Can a Florida Prenuptial Agreement Cover?
Section 61.079 gives couples considerable freedom. The statute lists specific subjects the parties may address, followed by a catchall that permits nearly anything else that does not violate public policy or criminal law.
Rights in Property Owned Now or Acquired Later
Couples may define the rights and obligations of each spouse in property belonging to either or both of them, whenever and wherever acquired or located. This is the core of most prenups. Without an agreement, Florida’s equitable distribution statute determines which assets are marital and which are nonmarital. Income earned during the marriage is generally marital, and the increase in value of a nonmarital asset can become marital if it results from the efforts of either spouse or the use of marital funds.
A prenup can override those default rules. For example, a couple may agree that each person’s earnings remain separate, that a premarital home stays nonmarital even if marital funds pay down the mortgage, or that growth in a family business belongs solely to the spouse who owns it.
Management and Control of Property
The statute permits agreements about the right to buy, sell, use, transfer, lease, mortgage, encumber, and otherwise manage property. Couples who own rental properties, investment accounts, or business interests often use these provisions to confirm that one spouse can make decisions about certain assets without the other’s consent.
Disposition of Property at Divorce, Death, or Another Event
Couples may decide in advance how property will be divided upon separation, dissolution of marriage, death, or the occurrence or nonoccurrence of any other event. That last phrase allows for creative drafting, such as provisions that change depending on how long the marriage lasts or whether the couple has children.
Spousal Support
The act expressly allows the parties to establish, modify, waive, or eliminate spousal support. This is one of the most significant provisions in the statute and is discussed in more detail below.
Wills, Trusts, and Life Insurance
A prenup may require either spouse to make a will, trust, or other arrangement to carry out the agreement. It may also address ownership rights in and disposition of the death benefit from a life insurance policy. These provisions are especially common when one spouse wants to guarantee a specific financial result for the other at death, or when a spouse with children from a prior relationship wants to preserve assets for them.
Choice of Law
Couples may select which state’s law will govern the construction of the agreement. For couples who may relocate, or who have ties to more than one state, this provision adds predictability.
Any Other Matter Not Against Public Policy
Finally, the statute allows the parties to address any other matter, including personal rights and obligations, as long as it does not violate public policy or a statute imposing a criminal penalty. This catchall gives couples room to address issues like pets, debt allocation, attorney’s fees in a future divorce, and responsibility for household expenses. Lifestyle clauses, such as provisions tied to infidelity, are a gray area, and their enforceability depends heavily on how they are drafted.
How Does a Prenup Affect Alimony in Florida?
Spousal support is often the most heavily negotiated section of a premarital agreement, and Florida law gives couples wide latitude. Under section 61.079, the parties can set a specific amount of alimony, cap it, limit its duration, tie it to the length of the marriage, or waive it entirely.
The alimony landscape in Florida changed significantly in 2023, when the Legislature eliminated permanent alimony. The types of alimony now available in a Florida divorce are temporary, bridge-the-gap, rehabilitative, and durational. Durational alimony is subject to limits based on the length of the marriage, and courts must weigh a detailed list of statutory factors. Many engaged couples, and the Tampa alimony lawyers advising them, now view the prenup as a way to add certainty on top of these reforms rather than leaving support entirely to judicial discretion.
A few limits apply. The act contains a safety valve: if a provision that modifies or eliminates spousal support would leave one spouse eligible for public assistance at the time of separation or divorce, the court may require the other spouse to provide support to the extent necessary to avoid that eligibility, regardless of what the agreement says. In other words, a prenup cannot be used to shift a former spouse’s support onto taxpayers.
Temporary support during a pending divorce is another area where careful drafting matters. Florida courts have historically been skeptical of waivers of support that would apply while the case is still pending, and the case law on this issue has evolved over time. A Florida alimony attorney drafting a support waiver will usually address temporary support separately and explicitly rather than assuming a general waiver covers it.
Because the alimony provisions of a prenup may not be tested for decades, they should be written with an eye toward how circumstances might change. An alimony lawyer in Tampa can help couples think through scenarios such as one spouse leaving the workforce to raise children, a significant income disparity developing over time, or a disability that affects earning capacity.
What Can a Florida Prenup Not Do?
Freedom of contract has limits, and Florida law draws several firm lines.
Child Support Cannot Be Waived or Limited
The statute states plainly that the right of a child to support may not be adversely affected by a premarital agreement. Child support belongs to the child, not to the parents, so parents cannot bargain it away before the child is even born. Any provision that attempts to waive, cap, or eliminate child support will be disregarded by the court.
Time-Sharing and Parental Responsibility Are Decided by the Court
Florida courts have long held that matters involving children, including parental responsibility and time-sharing, must be decided according to the best interests of the child at the time of the dispute. A prenup that attempts to decide which parent will have the children, or how time will be divided, will not bind a family court. Parents can express shared values in an agreement, but a judge will make the actual determination based on the circumstances at the time.
Provisions Against Public Policy or Criminal Law
The catchall provision permits any other matter only if it does not violate public policy or a statute imposing a criminal penalty. A provision requiring illegal conduct is unenforceable. Provisions that attempt to strip a court of its authority over matters that must be decided by the court, such as the welfare of children, also fall outside what the statute allows.
Support That Would Leave a Spouse on Public Assistance
As noted above, a support waiver will not be enforced to the extent it would leave a spouse eligible for public assistance at the time of separation or divorce.
Well-drafted Florida prenups typically include a severability clause so that if one provision is found unenforceable, the rest of the agreement remains intact. Without that clause, a single problematic term can create arguments that the entire agreement should fall.
When Can a Florida Prenup Be Set Aside?
The enforcement section of the act is where many prenup disputes are won or lost. Under section 61.079, a premarital agreement is not enforceable if the party challenging it proves one of the following grounds.
The Agreement Was Not Signed Voluntarily
A spouse who did not execute the agreement voluntarily can ask the court to set it aside. Questions about voluntariness often focus on the circumstances of signing: how close to the wedding the agreement was presented, whether the challenging spouse had time to review it, whether that spouse had access to independent legal advice, and whether there was any pressure to sign.
Fraud, Duress, Coercion, or Overreaching
The agreement is also unenforceable if it was the product of fraud, duress, coercion, or overreaching. Fraud might involve lying about assets or income. Duress and coercion involve improper pressure, such as a threat to call off the wedding at the last moment after guests have traveled and deposits have been paid. Overreaching refers to one party taking unfair advantage of the other, often through a combination of unequal bargaining power, lack of information, and one-sided terms.
Unconscionability Combined With Lack of Disclosure
The third ground is more technical. A spouse can invalidate an agreement by proving that it was unconscionable when signed and that, before signing, three conditions were all true. First, the challenging spouse was not provided a fair and reasonable disclosure of the other party’s property or financial obligations. Second, the challenging spouse did not voluntarily and expressly waive, in writing, any right to disclosure beyond what was provided. Third, the challenging spouse did not have, and reasonably could not have had, adequate knowledge of the other party’s property or financial obligations.
All of those conditions must be met. An agreement that is lopsided, but was signed after full financial disclosure, is generally enforceable. The question of unconscionability is decided by the judge as a matter of law.
The burden of proof falls on the spouse challenging the agreement. That structure favors enforcement, but it does not make an agreement immune from attack. A challenge can be expensive and emotionally draining even when it fails, which is why the best protection is a clean, well-documented signing process.
Why Is Financial Disclosure So Important?
Disclosure deserves special attention because it is the element that most often determines whether an agreement survives a challenge. Although the statute technically allows a spouse to waive disclosure in writing, relying on a waiver is risky. The stronger practice is to attach detailed financial disclosures to the agreement itself.
A thorough disclosure typically lists each party’s assets with approximate values, liabilities, income from all sources, business interests, retirement accounts, and anticipated inheritances or trust interests where known. Many attorneys also recommend attaching recent tax returns or financial statements. The disclosure does not need to be accurate to the dollar, but it should be fair and reasonable, meaning it gives the other spouse a realistic picture of what they are agreeing to.
Understating the value of a business, omitting an account, or failing to mention significant debt creates exactly the kind of evidence a challenging spouse would use later. Conversely, a signed acknowledgment that each spouse received and reviewed the other’s disclosure is powerful evidence that the agreement was entered into knowingly.
For couples with complex finances, such as business owners, physicians with practice interests, or beneficiaries of family trusts, a Tampa prenuptial agreement lawyer may recommend involving an accountant or valuation professional so the disclosure reflects realistic values rather than rough guesses.
How Do Prenups Interact With Florida Homestead and Inheritance Rights?
Many engaged couples focus on divorce and overlook what happens at death. In Florida, a surviving spouse has significant rights that exist regardless of what the other spouse’s will says. These include homestead protections under the Florida Constitution, the elective share (which generally entitles a surviving spouse to 30 percent of the elective estate), intestate inheritance rights, a family allowance, exempt property, and a preference to serve as personal representative.
Those rights can be waived, but the waiver is governed by the Florida Probate Code in section 732.702, not only by the premarital agreement statute. Under that section, a waiver must be in writing and signed by the waiving spouse in the presence of two subscribing witnesses. Notably, if the waiver is signed before marriage, no financial disclosure is required. If it is signed after marriage, each spouse must make a fair disclosure of their estate.
This is one reason a prenup is often more practical than a postnup for estate planning purposes. It is also why the signing ceremony matters. A prenup that is otherwise valid for divorce purposes could fail to waive inheritance rights if the witness requirement is not satisfied.
Coordination with estate planning documents is essential. If a prenup states that a spouse waives homestead rights, the couple’s wills, trusts, and deeds should be consistent with that plan. A Tampa family law attorney who handles premarital agreements will frequently work alongside the couple’s estate planning attorney so the documents do not contradict one another.
Can a Florida Prenup Be Changed After the Wedding?
Circumstances change. A couple may have children, start a business, receive an inheritance, or simply decide the original terms no longer fit. Section 61.079 allows a premarital agreement to be amended or revoked after marriage, but only by a written agreement signed by both parties. Like the original prenup, an amendment or revocation is enforceable without consideration.
Neither spouse can change the agreement unilaterally, and informal conduct, such as commingling funds or verbally agreeing to ignore a provision, does not amend the contract. Couples who want to update their agreement should do so formally, with the same care that went into the original. Because an amendment signed after marriage may also affect estate rights, the disclosure and witness requirements discussed above should be considered.
Some couples build review or sunset provisions into the original agreement. For example, an agreement might provide that the spousal support waiver expires after 15 years of marriage, or that certain provisions will be revisited after the birth of a child. These provisions can reduce the need for later amendments while still reflecting the reality that a marriage evolves.
What Happens If the Marriage Is Void or a Claim Is Delayed?
The act addresses two less common but important situations.
If a marriage is later determined to be void, for example because one party was still legally married to someone else, the premarital agreement is enforceable only to the extent necessary to avoid an inequitable result. The court has flexibility to use the agreement where fairness requires it, without treating it as fully binding.
The statute also addresses timing. Any statute of limitations applicable to a claim for relief under a premarital agreement is tolled during the marriage. However, equitable defenses such as laches and estoppel remain available. In practical terms, a spouse generally does not lose the right to challenge or enforce an agreement simply because years have passed during the marriage, but unreasonable delay or conduct inconsistent with the agreement can still affect the outcome.
What About Prenups Signed Before October 1, 2007?
Couples who signed a premarital agreement before the act took effect are not governed by section 61.079. Those agreements are evaluated under prior Florida case law. Under that earlier framework, courts could set aside an agreement if it was the product of fraud, deceit, duress, coercion, misrepresentation, or overreaching. Courts could also set it aside if it was unfair or unreasonable to the challenging spouse and the other spouse had not made fair disclosure, or the challenging spouse lacked a general and approximate knowledge of the other’s finances.
This distinction matters mostly for couples in longer marriages who are now reviewing an older agreement, whether because of a potential divorce or as part of estate planning. The date of signing determines which rules apply.
What Practical Steps Should Engaged Couples in Tampa Take?
Knowing the statute is one thing. Using it to create an agreement that reflects both partners’ goals and holds up over time is another. Several practical steps make a meaningful difference.
Start Early
Florida does not impose a mandatory waiting period between signing a prenup and the wedding. Even so, timing is one of the most common issues in enforcement disputes. An agreement presented days before the ceremony invites arguments about duress and lack of time to review. Beginning the process several months before the wedding gives both parties time to negotiate, consult counsel, and sign without pressure.
Each Spouse Should Have Independent Counsel
The statute does not require each party to have a lawyer. However, independent representation is one of the strongest indicators that an agreement was signed voluntarily and knowingly. A single attorney cannot represent both spouses in a prenup negotiation because their interests are adverse. When each spouse has their own attorney who explains the agreement, the risk of a successful challenge drops considerably.
Exchange Complete Financial Disclosures
Full disclosure is the backbone of an enforceable agreement. Both spouses should disclose, and the disclosures should be attached to the agreement.
Draft Clearly and Specifically
Ambiguity leads to litigation. Terms like “separate property,” “marital home,” or “business interests” should be defined. Formulas for support or property payments should be written so that a court can apply them without guessing what the parties intended.
Coordinate With Estate Planning
If the agreement affects inheritance rights or requires life insurance, trusts, or wills, those documents should be prepared or updated so they align with the prenup.
Keep Records of the Process
Drafts, correspondence showing negotiation, dates on which the agreement was delivered, and acknowledgments of disclosure all help demonstrate that the agreement was the product of a fair process.
Why Work With a Tampa Prenuptial Agreement Lawyer?
Online templates cannot account for Florida’s specific requirements, the interaction between the premarital agreement statute and the probate code, or the recent changes to Florida’s alimony law. They also cannot identify the particular risks in a couple’s financial picture, such as a closely held business, a pending inheritance, or significant premarital debt.
An experienced Tampa prenuptial agreement lawyer brings an understanding of how Hillsborough County judges evaluate these agreements, what kinds of provisions tend to draw challenges, and how to structure the signing process so the agreement stands on solid ground. Just as important, a skilled prenup attorney in Tampa can help couples approach the process as a collaborative planning exercise rather than a confrontation. Many couples find that working through a prenup strengthens their communication about finances, which benefits the marriage whether or not the agreement is ever used.
For the spouse being asked to sign, independent counsel ensures the terms are understood and that any concerns are raised before the wedding, when there is still room to negotiate. For the spouse requesting the agreement, a carefully drafted document protects the very assets and expectations that motivated the request in the first place.
Frequently Asked Questions About Florida Prenuptial Agreements
Does a Florida prenup have to be notarized?
Section 61.079 only requires that the agreement be in writing and signed by both parties. However, if the agreement waives inheritance rights such as the elective share or homestead, Florida’s probate code requires two subscribing witnesses. Most attorneys have prenups signed before two witnesses and a notary to avoid any issues.
Can a prenup waive alimony in Florida?
Yes. Florida law allows couples to establish, modify, limit, or completely waive spousal support in a premarital agreement. The main exception is that a court can order support if the waiver would leave a spouse eligible for public assistance at the time of separation or divorce.
Can we decide child custody or child support in our prenup?
No. A premarital agreement cannot adversely affect a child’s right to support, and decisions about parental responsibility and time-sharing are made by the court based on the child’s best interests at the time. Couples can address many other financial matters, but issues involving children remain under the court’s authority.
How far before the wedding should we sign?
Florida does not have a required waiting period, but signing well in advance strengthens the agreement. Many attorneys recommend finalizing the agreement at least 30 days before the wedding and starting the process several months earlier. Last-minute agreements are more vulnerable to claims of duress or coercion.
Do both of us need separate lawyers?
Florida law does not require it, but it is strongly recommended. One attorney cannot ethically represent both spouses in negotiating a prenup, and independent counsel for each party is strong evidence that the agreement was signed voluntarily and with full understanding.
What happens if my spouse hid assets when we signed?
Hidden assets can be grounds to challenge the agreement. If the agreement was the product of fraud, or if it was unconscionable and you did not receive fair disclosure or have adequate knowledge of your spouse’s finances, a court may refuse to enforce it. The burden is on the spouse challenging the agreement to prove these grounds.
Can we change our prenup after we are married?
Yes. A Florida premarital agreement can be amended or revoked after marriage, but only through a written agreement signed by both spouses. Verbal agreements or informal conduct will not change the terms.
Is a prenup signed in another state valid in Florida?
Generally, yes, if it was valid in the state where it was signed. Many agreements include a choice of law clause specifying which state’s law applies. Couples who relocate to Tampa with an existing agreement should still have it reviewed to understand how it interacts with Florida’s homestead, inheritance, and alimony laws.
Talk to a Tampa Prenup Attorney Before the Wedding
A premarital agreement is one of the few legal documents that can shape a couple’s financial life for decades. Florida’s Uniform Premarital Agreement Act gives engaged couples real flexibility, but that flexibility comes with requirements that must be followed carefully. If you are engaged and considering a prenuptial agreement, or if you have been asked to sign one, speaking with a Florida prenuptial agreement attorney early in the process is the most reliable way to protect your interests and start your marriage with clarity.
