If you're already married and never signed a prenup, a postnuptial agreement can give you much of the same financial clarity. A prenup attorney can draft one after the wedding to spell out what stays separate, what is shared, and what happens to specific assets if the marriage ends or one spouse dies.
Missing the prenup window is common, and it doesn't mean the door has closed. At Frank Family Law Practice, we handle these agreements quietly and with care, from our office in Winter Park. If you've been thinking about one, reach out to our team for a private consultation at (407) 629-2208.
How is a postnuptial agreement different from a prenup?
The main difference is timing. A prenup is signed before the wedding, and a postnup is signed after it, which in Florida puts a little more weight on full disclosure and fairness.
Both agreements can cover the same ground: which property stays separate, how marital assets would be divided, whether alimony is limited or waived, and who keeps a business or a home. What changes is the relationship when you sign. Before a wedding, the two of you are separate people negotiating. After it, you already owe each other legal duties as spouses, so courts look closely at whether each person knew what they were giving up. That's why careful drafting matters more, not less.
Couples usually pursue a postnup when something shifts after the wedding. Think of a lakefront house on the Winter Park Chain of Lakes bought partly with one spouse's savings, or a second marriage where each spouse wants to protect the children from a first one. Our page on prenuptial and postnuptial agreements covers both types. The goal is the same either way: fewer surprises and fewer arguments later.
What usually prompts a couple to get a postnuptial agreement?
Most postnups start with a change in the money picture. The most common triggers are a new business, an inheritance, a large gift from family, or one spouse leaving work to raise children.
A business is a frequent reason. If one spouse opens a shop or a professional practice on Park Avenue, the growth in that business during the marriage can become marital property. A postnup can set out who owns it, how its value would be measured, and whether the other spouse has a claim to it.
Inheritances come up just as often. Under Florida law, an inheritance generally starts out as separate property, but that protection can wear away if it gets mixed with marital money or used as the family home. We saw this with a recently married couple in Winter Park who were caught off guard when the husband inherited a family home. A postnuptial agreement helped them safeguard that family legacy, with clear terms both spouses understood.
What makes a postnuptial agreement enforceable in Florida?
It needs to be in writing, signed voluntarily by both spouses, and based on fair and full financial disclosure. An agreement signed under pressure, or without knowing what the other spouse owns, is open to challenge.
In practice, that means each spouse shares a complete picture of assets, debts, and income before signing, usually in a written financial disclosure attached to the agreement. Each spouse should also have their own lawyer, because separate counsel is often what keeps the agreement standing years later. The terms shouldn't be so one sided that they look unfair on their face, and nobody should be handed the document the night before a major event and told to sign.
Two limits are worth knowing. A Florida court will always decide child support, custody, and time sharing based on the children's best interests at the time, so an agreement can't lock those in. And if a home becomes your Florida homestead, like many houses in the historic neighborhoods around Rollins College, a spouse's rights in that home can only be waived after marriage with fair disclosure. A careful draft addresses both.
Can a prenup attorney keep the postnup process collaborative?
Yes. Most postnups are negotiated by two spouses who want to stay married, and the process should feel that way. The aim is a shared understanding, not a fight.
We often use a collaborative law approach for marital agreements. Each spouse has their own attorney, the conversations stay private, and the work happens around a table instead of through demand letters. That keeps the focus on what each of you needs to feel secure, whether that's protecting a family property, a business, or children from an earlier marriage. Discretion matters too. We know many clients would rather keep this conversation between the two of them and their lawyers. Some couples also build in a review date, so the agreement can be updated if a child is born, a business grows, or another inheritance arrives.
