Why More Florida Couples Are Seeking Postnuptial Agreements After Major Life Changes

You said “I do” years ago, but life has thrown a few curveballs since then. Maybe you started a business that took off, maybe you inherited a beach condo from an aunt you barely knew, or maybe you are simply rebuilding trust after a rough patch. So here is a question worth asking: if your finances and your marriage look nothing like they did on your wedding day, shouldn’t the paperwork protecting both catch up too? A growing number of Florida couples are answering that question with a postnuptial agreement.

Life Doesn’t Pause Just Because You’re Married

A prenup gets signed before the wedding, back when your future together was still mostly theoretical. A postnuptial agreement is the more grown up cousin, signed after the wedding, once real life has actually happened. Couples turn to them for all sorts of reasons, and lately we have noticed a pattern. The most common triggers tend to include:

• A sudden increase in income or the launch of a successful business
• An inheritance or windfall one spouse wants to keep clearly defined
• A career change where one spouse steps back to raise children or manage a household
• Rebuilding a marriage after infidelity or a serious rough patch
• Blending families and wanting clarity for children from a previous relationship

None of these situations mean a marriage is failing. If anything, sitting down to talk finances openly is often a sign of two people taking their partnership seriously.

What Does a Postnup Actually Need to Hold Up in Court?

Here is where things get interesting. Florida does not have a tidy little statute spelling out exactly how postnuptial agreements work, the way it does for prenups. Instead, Florida courts rely on the standard set by the Florida Supreme Court in Casto v. Casto, 508 So. 2d 330 (Fla. 1987). Under Casto, a postnuptial agreement can be challenged and potentially set aside on one of two grounds: if it was the product of fraud, duress, coercion, or overreaching, or if it makes an unfair or unreasonable provision for one spouse and that spouse lacked full knowledge of the other’s finances.

Translation? Honesty and full financial disclosure are not optional extras. They are the entire foundation the agreement stands on.

Why Timing and Transparency Matter So Much

Because postnups are signed between spouses who already owe each other fiduciary duties, Florida courts tend to look at them a bit more closely than prenups negotiated by two people who were still, legally speaking, strangers. That extra scrutiny is exactly why vague financial disclosures or a rushed signature can come back to haunt an otherwise well-intentioned agreement years later.

Thinking About a Postnup? Let’s Get the Details Right

A postnuptial agreement is not an admission that your marriage is on shaky ground. It is a practical tool for couples whose circumstances have genuinely changed, and getting the details right the first time matters far more than people expect.
