The Bottom Line
Martin County's median home price of $507,500 means most Treasure Coast couples have significant assets at stake — a properly drafted prenuptial agreement under Florida §61.079 protects those assets and can prevent years of costly litigation if the marriage ends.
Martin County's median single-family home price as of January 2026, well above Florida's $410,000 median.
Average student loan debt per Florida borrower — a liability a prenup can shield from a spouse.
Florida prenup cost range, from simple agreements to complex ones involving businesses or investment property.
What You Need to Know
Florida courts void prenuptial agreements that lack full financial disclosure or show signs of duress — including agreements handed to a partner just days before the wedding. The Fourth District Court of Appeal struck down one prenup where the bride received it two days before the ceremony with no disclosure and an ultimatum. Having both parties retain independent counsel is the single strongest defense against a future enforceability challenge.
A prenup cannot predetermine child support or custody — any such provision is void under §61.079(3)(b) and can complicate the rest of the agreement. Florida's 2023 alimony reform, which eliminated permanent alimony, makes precisely drafted spousal support provisions more critical than ever, since courts now apply stricter durational limits that a well-crafted prenup can work alongside rather than against.
What To Do Next
Hire a Florida family law attorney at least 60–90 days before the wedding to allow time for proper drafting.
Compile a complete financial disclosure — assets, debts, retirement accounts, and property — before your first attorney meeting.
Ensure your partner retains separate independent counsel to prevent future voluntariness challenges.
If already married, consult a family law attorney about a postnuptial agreement, which Florida courts enforce under the same standards.
Pair your prenuptial agreement with an updated estate plan if you have children from a prior relationship to protect their inheritance.

The Treasure Coast takes its name from the Spanish galleons that sank off its shores in 1715, carrying gold and silver worth millions — and the lesson from that disaster still applies today: wealth unprotected is wealth at risk. As of January 2026, Martin County's median single-family home price stood at $507,500, well above Florida's statewide median of approximately $410,000, according to Florida Realtors market data. That means couples marrying in Stuart, Port St. Lucie, or Jensen Beach are often bringing a waterfront property, a small business off Kanner Highway, or a retirement account into the marriage — along with, in many cases, significant debt. A prenuptial agreement lawyer helps both partners protect what they are bringing in and clarify what happens if things do not work out.
Every Treasure Coast Marriage Starts With Real Assets Worth Protecting
Martin County's median home value — consistently above Florida's statewide median of roughly $410,000 — tells the story clearly: the average couple here has more at stake than they realize. Indian River County home prices fell approximately 16% year-over-year by early 2025, according to WPTV's reporting on Florida Association of Realtors data, a reminder that market swings make advance planning more valuable, not less. Florida also carries one of the nation's largest student loan burdens — 2.7 million borrowers owing a collective $105.5 billion, averaging roughly $39,000 per borrower, according to Axios — so one spouse's debt is as real a consideration as one spouse's home.

A prenuptial agreement, called a premarital agreement under Florida law, is a legal document both parties sign before the wedding to define how assets and debts will be handled if the marriage ends. It is not a prediction of divorce. It is a financial plan that protects both people. A prenuptial agreement lawyer ensures the document meets Florida's legal standards and reflects each party's actual financial picture. If you want to understand how to choose the right divorce lawyer for this process, the same principles apply when selecting a prenuptial agreement attorney: local experience, Florida-specific knowledge, and a track record with complex asset structures matter most.
What Florida Law Actually Requires for a Prenuptial Agreement to Hold Up in Court
Florida prenuptial agreements are governed by the Florida Premarital Agreement Act, codified at Florida Statutes §61.079. Courts in Martin and St. Lucie Counties enforce them — or throw them out — based on four requirements. The checklist below covers what courts actually look for.
4 Legal Requirements Florida Courts Use to Decide If a Prenup Is Enforceable — Source: Florida Statutes §61.079 (leg.state.fl.us); Florida 4th DCA, 2007 (law.justia.com)
Both Parties Must Provide Full Financial Disclosure
Under §61.079(7), a prenup is unenforceable if one party was not given fair and reasonable disclosure of the other's property or financial obligations before signing. Full disclosure is not optional — it is a legal standard. In a 2024 ruling, a Florida appellate court held that a prenup's validity must be determined before a court can order financial discovery, according to a case update published by the American Bar Association. That ruling underscores how seriously Florida courts treat the disclosure question.
The Agreement Must Be Voluntary and Free of Pressure
Florida courts assess the totality of circumstances to decide if a signature was voluntary. Timing is the most common problem — and one of the first things a prenuptial agreement lawyer will address when structuring the process. Florida's Fourth District Court of Appeal upheld a prenup where the bride executed it just two days before the wedding finding that the parties had been negotiating the agreement over a period of months, the Husband had provided a full financial disclosure all prior to the ultimatum, the decision in Francavilla v. Francavilla. The court held, however, that simply insisting on a prenup as a condition of marriage "does not constitute duress" when both parties have adequate time and independent counsel.
Written, Signed, and Properly Executed
Florida law requires the agreement to be in writing and signed by both parties. No additional consideration beyond the marriage itself is required. While Florida's statute does not mandate notarization for prenups signed after 2007, having the document executed before a certified notary public and witnessed is standard best practice — it strengthens credibility if the agreement is ever challenged in court and is necessary if the agreement affects real estate transfer. A prenuptial agreement lawyer will typically handle these execution details to ensure nothing is overlooked.
What a Prenuptial Agreement Can and Cannot Cover Under Florida Law
Couples are often surprised by how much Florida law allows — and what it prohibits.
What a Florida Prenuptial Agreement Can and Cannot Cover — Source: Florida Statutes §61.079 (leg.state.fl.us); flsenate.gov, 2021
Marital Property, Non-Marital Property, and Debt Allocation
Under §61.079(3), a prenuptial agreement can designate which assets remain the separate property of one spouse, how property acquired during the marriage will be treated, and who carries responsibility for existing debts. A home on the St. Lucie River or in Port Saint Lucie owned before the wedding can be protected as non-marital property. A business loan one party took out can be kept off the other's liability. Florida law gives wide latitude to predetermine asset and debt division as long as the terms are not unconscionable.
Spousal Support and Alimony Provisions
A prenup can waive, limit, or define spousal support. Florida law permits this, but one notable statutory exception applies: if enforcing an alimony waiver would leave one spouse eligible for public assistance, a court has the discretion to override the waiver to the extent necessary to avoid that outcome. Florida's alimony statute was significantly amended in 2023, eliminating permanent alimony and restructuring durational limits — changes detailed in our guide to alimony changes in Florida. That legislative shift makes updated, precisely drafted alimony provisions in premarital agreements more important than ever, and a prenuptial agreement lawyer familiar with the 2023 changes is best positioned to draft them correctly.
Why Child Support and Custody Cannot Be Controlled by a Prenup
Florida law prohibits prenuptial agreements from predetermining child support obligations or child custody arrangements. Courts retain full authority to set timesharing and support based on the best interests of the child at the time of divorce, regardless of what any agreement says. Under §61.079(3)(b), any provision attempting to limit child support is void. Including such language does not just fail — it can create complications for the rest of the agreement.
Who Actually Needs a Prenuptial Agreement Lawyer on the Treasure Coast
More Treasure Coast couples would benefit from a prenup than assume they would. The region's mix of retirees, waterfront property owners, small business owners, and blended families creates exactly the situations where a premarital agreement is not just reasonable — it is advisable.
Couples Where One Spouse Brings Significant Assets or Debt
If one party owns a home in Palm City, operates a marine business near the Indian River Lagoon, carries a retirement account, or has inherited property along Hutchinson Island, a prenup can establish those assets as non-marital property and define how future appreciation is treated. The reverse applies as well: if one spouse carries significant student loan debt or a business liability, the agreement can define which spouse bears responsibility for that obligation in the event of divorce — providing an important layer of financial clarity. Any meaningful financial imbalance between partners is sufficient reason to consult an experienced Florida family law attorney.
Business Owners and High Net Worth Individuals
For business owners, a prenuptial agreement is less optional and more essential. Without one, Florida's equitable distribution rules could entitle a spouse to a share of business value — including appreciation during the marriage. Florida courts distinguish between passive appreciation (generally the non-owning spouse's claim) and active appreciation tied to marital effort, and that line becomes expensive to litigate. An experienced prenuptial agreement attorney drafts around these distinctions from the start.
Blended Families With Children From Prior Relationships
A prenuptial agreement allows a parent to protect assets intended for children from a prior relationship. Without one, Florida's intestate succession rules and equitable distribution law could redirect those assets to a new spouse. Treasure Coast families with children from previous marriages should pair a prenup with an updated estate plan — the two documents work together. Questions about paternity or existing child support obligations from prior relationships should also be addressed with your attorney at this stage.
The Difference Between a Prenuptial Agreement and a Postnuptial Agreement
Florida also recognizes postnuptial agreements — contracts signed after the wedding that accomplish many of the same goals as a premarital agreement.

When a Postnuptial Agreement Makes Sense
Financial issues in a marriage often lead to Divorce. According to Debt.com's annual 2025 study , 42% of divorcing couples in the study said credit card debt played a role in their decision to seek a divorce, up from 34% in 2024 and 29% in 2023. A postnuptial agreement can address the financial problems that place a strain on a couple's relationship. A postnuptial agreement may also be appropriate when spouses want to establish or revise financial terms mid-marriage due to life events — for example, after one partner starts a business, receives a significant inheritance, or the couple realizes they never addressed property division before the wedding. In these situations, consulting a prenuptial agreement lawyer early — even retroactively — can clarify which type of agreement best fits the couple's circumstances. An experienced Martin County divorce mediation attorney can also help structure a postnuptial agreement to address the same range of issues as a prenup, often through a collaborative process that reduces conflict.
How Courts Treat the Two Documents
Florida courts apply the same general enforceability standards to both prenuptial agreements and postnuptial agreements, including the full disclosure requirement and the voluntariness standard. Postnuptial agreements can face slightly heightened scrutiny because of the ongoing fiduciary relationship between spouses. The drafting standard should be equally rigorous — an informal arrangement documented after the fact rarely survives a serious legal challenge.
How Much a Prenuptial Agreement Costs in Florida and What Drives the Price
Cost is typically the first question Treasure Coast couples ask, and the honest answer depends on complexity.
Florida Prenuptial Agreement Costs: From Simple to Complex — Source: ContractsCounsel Florida Prenuptial Agreement Cost Data, 2025–2026
Typical Cost Range for Florida Prenuptial Agreements
Simple prenuptial agreements for couples with straightforward finances typically run $1,500 to $3,000 when each spouse retains independent counsel, with most couples paying $2,500 to $5,000 total for both attorneys, according to current Florida market data from ContractsCounsel. More complex agreements — involving businesses, investment properties, or detailed property schedules — typically range from $3,000 to $10,000 or more, depending on asset complexity and the expertise of counsel retained. Not an insignificant investment, but considerably less than the expense of litigating these issues in a Divorce. Having both parties retain separate counsel increases total cost but significantly strengthens enforceability.
Why a Template Prenup Is a False Economy
Online templates are not tailored to Florida law and do not account for your specific asset structure. A document that fails in court is worse than having no agreement at all — it creates false confidence while leaving both parties exposed. Florida courts have invalidated template-style or attorney-unreviewed agreements for failing to meet the requirements of §61.079. A prenuptial agreement lawyer drafts a legal document that is built to hold up if it is ever challenged.
Frequently Asked Questions About Prenuptial Agreements in Florida
How much does a prenup cost in Florida? Florida prenuptial agreements typically start around $1,500 to $3,000 for straightforward situations, with most couples paying $2,500 to $5,000 total when both parties retain separate counsel, according to ContractsCounsel marketplace data. Complex agreements involving businesses or investment property can reach $10,000 or more. Experienced family law attorneys strongly recommend independent representation for both parties to prevent future challenges on voluntariness grounds.
What a Florida Prenuptial Agreement Can — and Cannot — Cover — Source: Florida Statutes §61.079; flsenate.gov
Can you write your own prenup without a lawyer? You can, but Florida courts can invalidate a valid prenuptial agreement that fails to meet the requirements of §61.079, including full financial disclosure and voluntary execution. A self-drafted agreement that omits required elements or contains ambiguous language provides little real protection — and false protection is worse than none.
How much money justifies a prenup? There is no dollar threshold in Florida law, and that framing misses the point. Any couple where one spouse owns a home, operates a business, has retirement savings, carries substantial debt, or has children from a prior relationship has something worth protecting. On the Treasure Coast, where Martin County home prices regularly exceed state averages, even couples who consider themselves middle-class often have significant assets that a prenuptial agreement should address. Understanding how long a divorce takes in Florida also puts the value of advance planning in perspective — contested divorces without a prenup can drag on for years.
Can cheating void a prenup in Florida? Florida is a no-fault divorce state, so infidelity does not directly affect divorce proceedings and generally cannot void a prenuptial agreement on its own. Some agreements include infidelity clauses with specific financial consequences. Florida courts have not definitively ruled on the enforceability of these clauses — as legal commentators note, there is no Florida case that conclusively settles the issue — so they require careful construction and should be discussed thoroughly with your attorney before inclusion.
Can a prenuptial agreement cover what happens to our house in Port St. Lucie or Stuart? Yes. A prenuptial agreement can designate a home as non-marital property belonging to one spouse, determine how any appreciation in value is treated, and specify what happens to the property in the event of divorce or death. This is one of the most common uses for Treasure Coast couples who own waterfront or investment property before marriage. The agreement must specifically describe the property and the intended treatment to be enforceable. Treasure Coast Legal's Stuart office, located at 34 SE Osceola St, and the firm's Stuart-area office at 3601 SE Ocean Blvd serve clients throughout Martin and St. Lucie Counties who need precisely drafted real property provisions in their premarital agreements.
What about military couples stationed at or near the Treasure Coast? Active-duty service members and their spouses face unique considerations — deployments, VA benefits, military retirement division, and jurisdictional questions under the Servicemembers Civil Relief Act. Florida has specific procedures for military families. Our detailed guide to Florida's approach to military divorce covers how these factors intersect with prenuptial agreement planning.
Take This Step Before the Wedding Day
A prenuptial agreement is not a sign of distrust — it is a sign of preparation. Couples on the Treasure Coast who bring real assets, real businesses, and real families into a marriage deserve real legal services and a legal document that reflects those circumstances.
Waiting until the week before the wedding is the single biggest mistake Treasure Coast couples make. Florida courts look at timing when evaluating voluntariness, and a prenuptial agreement lawyer needs adequate time to complete financial disclosures and proper drafting. The earlier both parties engage their own counsel, the stronger the agreement.
