Prenups get the attention, but the agreement more couples actually need is the one signed after the wedding. A postnuptial agreement settles how property and support would be handled if the marriage ends — negotiated not in the glow of an engagement, but by two people who know exactly what their marriage looks like. Florida enforces postnups, businesses are protected by them, inheritances are ring-fenced by them, and more than a few marriages have been saved by the financial clarity they force. The Law Office of John Vernon Moore, P.A. brings over 89 years of combined experience to drafting and litigating marital agreements across Brevard County.
What a Postnuptial Agreement Can Do
Under Florida law, spouses may contract with each other about nearly everything financial: classifying property as marital or nonmarital — including assets acquired in the future; fixing how specific assets (a business, a professional practice, real estate) would be valued and divided; waiving or limiting alimony; defining responsibility for debts; and setting each spouse’s rights on death, including waivers of elective share and homestead rights that coordinate with estate planning. What a postnup cannot do: predetermine child support, timesharing, or parental responsibility — children’s issues are decided by courts at the time they arise, always. A postnup also cannot leave one spouse eligible for public assistance through an alimony waiver; courts can disregard waivers to that extent.
Why Couples Sign Them
The triggers are recognizably human. The business grew. A company started after the wedding — or grown dramatically since — is marital property; a postnup can fix its treatment now, while the couple agrees, instead of funding a valuation war later. The inheritance arrived. Inherited wealth stays nonmarital only if kept scrupulously separate — a postnup protects it even if it gets commingled. The reconciliation. Couples rebuilding after infidelity or a near-divorce often use a postnup to take the financial fear out of trying again — each spouse knows where they stand, so the work on the marriage is about the marriage. The second marriage. Blended families use postnups with estate plans to guarantee children from prior marriages inherit as intended. The missed prenup. Plenty of couples meant to sign one and ran out of runway before the wedding; the postnup is the same protection, signed late.
What Makes a Postnup Enforceable — and What Sinks One
Florida enforces postnuptial agreements that are (1) voluntary, and (2) either fair when signed or preceded by full and frank financial disclosure. Because spouses owe each other fiduciary-like duties, postnups are scrutinized more closely than prenups — the classic attack is that one spouse hid the true finances or pressured the other. The enforceability checklist we build to: complete written financial disclosure attached to the agreement (both sides, with values); independent counsel for each spouse — not legally mandatory, but the single strongest enforceability factor; time to review, with no signing under ultimatum during a crisis; clean drafting that avoids unconscionable lopsidedness; and execution formalities — signed, witnessed, notarized. An agreement missing these elements invites exactly the litigation it was written to prevent, and the attacks mirror those covered on our challenging a prenup page.
Postnup, Prenup, or Neither?
The prenup comparison is timing and leverage: prenups are negotiated between legally unrelated people and reviewed somewhat less strictly; postnups between fiduciaries, more strictly — meaning postnups must be cleaner to survive. Against no agreement at all, the comparison is certainty versus litigation: Florida’s default rules (equitable distribution, SB 1416 alimony) are sensible but generic, and their application to a specific business, a specific inheritance, or a specific blended family is exactly what gets litigated for six figures. Ten hours of drafting against two years of discovery is the honest math. With over 89 years of combined experience, our team drafts agreements built to hold — and reviews proposed ones with the same adversarial eye we bring to prenuptial work.
My spouse just asked me to sign a postnup. Should I be worried?
Be careful, not alarmed. Get your own lawyer — never share counsel — insist on complete financial disclosure, and take the time to understand every waiver, especially alimony and elective share provisions. A fair postnup protects both spouses; an unfair one is visible to trained eyes quickly.
Can a postnup save our marriage?
It resolves the financial dimension of marital conflict — which is a large dimension. Couples in counseling often find that settling the money questions removes the leverage and fear from the rest of the work. The agreement is a tool, not therapy; many couples use both deliberately.
Can we change or cancel it later?
Yes — by a written agreement signed with the same formalities. Life-stage updates (a business sold, children born, retirement) are common and advisable. What one spouse cannot do is change it unilaterally.
Will a Florida court really enforce our postnup in a divorce?
Properly executed agreements are enforced routinely — Florida respects spouses’ right to order their own affairs. The exceptions track the defects above: concealment, coercion, unconscionability without disclosure. Which is to say: enforceability is determined at drafting, not at trial.
