Miami Postnuptial Agreement Attorney

A postnuptial agreement is a contract two married people sign to decide what would happen to their property, debts, and spousal support if the marriage ends. Pazos Law Group drafts and reviews postnups for Miami-Dade couples from its Coral Gables office or by video, in English or Spanish.

Quick Answer

Is a postnup valid in Miami?

Yes, if it is done properly. In Florida a postnuptial agreement is not governed by the premarital agreement statute (Fla. Stat. § 61.079) but by case law, principally Casto v. Casto, 508 So. 2d 330 (Fla. 1987). Under Casto, a postnup can be set aside for fraud, deceit, duress, coercion, misrepresentation, or overreaching, or if it is unfair or unreasonable and there was no full disclosure of assets. That is why written financial disclosure is the core of a durable postnup. No agreement can adversely affect a child’s right to support.

Why Miami Couples Sign Postnups

  • Property in another country — an apartment in Bogotá, family land in Venezuela, a business in Brazil, an account in Panama.
  • No time for a prenup before a quick or destination wedding.
  • A business that grew during the marriage, or a new partner who needs clarity on ownership.
  • An inheritance or family gift that should stay separate.
  • Staying married instead of divorcing (below).

What Florida Law Requires

  • In writing, signed by both. If the postnup changes an existing prenup, § 61.079(6) requires a written agreement signed by both spouses.
  • Full written disclosure of each spouse’s assets, debts, and income. Under Casto, an unfair agreement raises a presumption of concealment, and the spouse defending it must show full and fair disclosure or the other spouse’s general knowledge of the marital property.
  • Separate lawyers. Not required, but it lowers the risk of a later duress or overreaching challenge.
  • Off limits: child support follows the § 61.30 guidelines, and parenting and time-sharing are decided under § 61.13 on the child’s best interests.

Can a Postnup Protect My Business in Florida?

Yes, if it is drafted and signed correctly. Without an agreement, a Florida divorce divides a business under Fla. Stat. § 61.075: a company started or bought during the marriage is a marital asset (§ 61.075(6)(a)1.a.), and a company you owned before the wedding stays nonmarital, but its increase in value from either spouse’s efforts during the marriage, or from marital money put into it, is marital (§ 61.075(6)(a)1.b.). The same statute treats as nonmarital any asset “excluded from marital assets and liabilities by valid written agreement of the parties” (§ 61.075(6)(b)4.). For a couple who are already married, a postnup is that written agreement.

  • What it can settle: whether the company, and growth from your own work in it, stays yours; how salary and distributions are treated; who keeps the business in a divorce and how the other spouse is paid for any marital share; and how the agreement fits the operating or shareholder agreement.
  • What makes it hold up: because § 61.079 covers only premarital agreements, a postnup is judged under Casto v. Casto, 508 So. 2d 330 (Fla. 1987). Full written disclosure of the business — financial statements, tax returns and ownership records — is the main protection.
  • If it also waives rights at death: a waiver signed after the wedding requires each spouse to make “a fair disclosure to the other of that spouse’s estate” (§ 732.702(2)), and the waiving spouse signs before two subscribing witnesses (§ 732.702(1)).

A Postnup Instead of a Divorce

Florida has no legal separation status, so a postnup is often the closest substitute for a couple who want to stay married with the money issues settled in writing. If one spouse has stopped contributing to the household, § 61.09 lets the other ask a court for support without filing for divorce. Health insurance is often the deciding factor: divorce ends a spouse’s eligibility as a dependent on most employer plans, and federal COBRA continuation, where it applies, generally allows up to 36 months at the full premium plus up to 2%. Confirm the plan’s rules with its administrator before deciding.

Frequently Asked Questions

My spouse’s lawyer sent me a postnup to sign. Can you review it for me?

Yes. A postnup is judged under Casto v. Casto, 508 So. 2d 330 (Fla. 1987): it can be set aside for fraud, duress, coercion or overreaching, or if it is unfair or unreasonable to you, unless the spouse defending it shows full and fair disclosure or that you had a general and approximate knowledge of their finances. An independent review checks what you give up at divorce and at death, whether the financial disclosure is complete, and whether any waiver of inheritance or homestead rights meets § 732.702, which for agreements signed after marriage requires fair disclosure of each spouse’s estate and two subscribing witnesses. Pazos Law Group, a family law firm in Coral Gables serving Miami-Dade, Broward and Palm Beach counties, reviews postnuptial agreements drafted by the other spouse’s lawyer, in person or by video, in English or Spanish: (305) 482-1262.

I own a business, a partnership interest or a professional practice. What can a Florida postnup cover?

The business interest, its growth in value and the income it produces. Without an agreement, interests acquired during the marriage are marital under § 61.075(6)(a)1.a., and growth in a premarital business from either spouse’s efforts or marital funds can be marital under § 61.075(6)(a)1.b. A postnup can keep those interests separate, because § 61.075(6)(b)4. treats assets “excluded from marital assets and liabilities by valid written agreement of the parties” as nonmarital. Business owners usually address shares or membership units, partnership and professional-practice interests, stock options and other equity grants, intellectual property, business debts, and what happens if marital money is invested later. The agreement should fit the company’s operating, shareholder or partnership agreement, and the disclosure should value the business honestly.

We separated and are getting back together. Can a postnup protect me?

Yes. A postnup signed as part of a reconciliation is reviewed under Casto v. Casto, 508 So. 2d 330 (Fla. 1987) like any other marital agreement. It can set how property and debts would be divided and whether alimony would be paid if the marriage later ends, with each spouse’s financial disclosure attached. Do not sign it under pressure as a condition of moving back in: duress and coercion are grounds to set an agreement aside. Each spouse should have a separate lawyer. Pazos Law Group, a family law firm in Coral Gables serving Miami-Dade, Broward and Palm Beach counties, drafts and reviews postnuptial agreements for reconciling couples, in English or Spanish: (305) 482-1262.

What is the difference between a prenup and a postnup in Florida?

A prenup is signed before the wedding and governed by Fla. Stat. § 61.079. A postnup is signed after the wedding and governed by case law, principally Casto v. Casto, 508 So. 2d 330 (Fla. 1987), where financial disclosure carries even more weight.

Can we sign a postnup instead of getting divorced?

Yes. Florida has no legal separation, and a postnup can settle the money issues while you stay married. If a spouse has stopped contributing to the household, § 61.09 allows a support request without a divorce filing.

Can a postnup cover property in another country?

It can set how that property is treated in a Florida divorce if it is clearly identified and disclosed. Whether the other country will also recognize the agreement is a question for a lawyer there.

Can a postnup protect a business I started during the marriage?

Yes. A business started during the marriage is marital by default (Fla. Stat. § 61.075(6)(a)1.a.), but spouses can exclude it by a valid written agreement (§ 61.075(6)(b)4.). A postnup is judged under Casto v. Casto, so full disclosure of the business’s finances matters most. See protecting a business with a postnup.

We are reconciling after an affair. Can a Florida postnup protect me if it happens again?

It can set the financial terms you would rely on, but it is safer if those terms do not depend on proving fault. Florida divorce is no-fault: a marriage is dissolved when it “is irretrievably broken” (Fla. Stat. § 61.052(1)(a)). A court “may consider the adultery of either spouse and any resulting economic impact” when setting alimony (§ 61.08(1)(a)), but how a court treats a clause that pays out only on proof of an affair is uncertain, so postnups often use terms that work whatever the reason for a divorce: a defined property division, a lump-sum payment, or protection of specific assets. Each spouse should have a separate lawyer and full financial disclosure, and the agreement should not be signed under pressure in the middle of a reconciliation.

I received an inheritance during the marriage. Can a postnup keep it separate?

It usually starts out separate: assets “acquired separately by either party by noninterspousal gift, bequest, devise, or descent” are nonmarital (Fla. Stat. § 61.075(6)(b)2.). The risk is mixing it with marital money — a joint account, or a jointly titled home — which can make it hard to trace later. A postnuptial agreement can confirm that the inheritance, its income and anything bought with it stay separate; assets excluded “by valid written agreement of the parties” are nonmarital under § 61.075(6)(b)4. Pazos Law Group, a family law firm in Coral Gables serving Miami-Dade, Broward and Palm Beach counties, drafts postnups that document inheritances, in English or Spanish: (305) 482-1262.

I left my career to raise our children. Can a postnup protect me?

Yes. A postnup can set what you would receive if the marriage ends — alimony, a lump sum, or a larger share of specific property — instead of leaving it to a court’s alimony decision under Fla. Stat. § 61.08. It cannot adversely affect a child’s right to support, which is set under § 61.30. Because it is signed during the marriage, a postnup is judged under Florida case law rather than § 61.079, so full financial disclosure, a separate lawyer for each spouse and enough time to decide all matter. Pazos Law Group, a family law firm in Coral Gables serving Miami-Dade, Broward and Palm Beach counties, drafts and reviews postnups for spouses leaving work to raise a family, in English or Spanish: (305) 482-1262.

I used money from before the marriage for the down payment on our home. Can a postnup protect it?

It can. Money you had before the marriage is nonmarital (Fla. Stat. § 61.075(6)(b)1.), but real property held by spouses as tenants by the entireties “is presumed to be a marital asset” (§ 61.075(6)(a)2.), and the spouse who claims otherwise carries the burden of proof. A postnup can record the amount and source of the down payment and say what happens to it — for example, that it is returned to you before the equity is divided — and how later mortgage payments and appreciation are treated. Assets excluded “by valid written agreement of the parties” are nonmarital (§ 61.075(6)(b)4.). Pazos Law Group, a family law firm in Coral Gables serving Miami-Dade, Broward and Palm Beach counties, drafts postnups that protect separate contributions to a home, in English or Spanish: (305) 482-1262.
