How Marriage Reaches Your Business
Even a business in your name alone is exposed. If you owned it before marriage it may be separate, but the increase in its value during the marriage, especially growth that came from your own work, is generally marital and divisible in a divorce. And at death, a surviving spouse’s elective share reaches the business as part of your estate. Either way, the company you built can be dragged into a personal fight.
What a Prenup Does for It
A prenup keeps the business, and its appreciation, on the separate side of the line, and waives the spousal claims that would otherwise reach it at divorce or death. For an owner with partners, it also protects them: nobody wants a co-owner’s ex-spouse or heirs holding a stake.

These pieces work as a set: the prenup keeps the interest separate, the buy-sell agreement controls what happens to it on death, disability, or divorce, and your trust or will routes ownership to the people you choose. Drafted together, they keep the company out of divorce court and probate. See business succession planning for the full picture.
Frequently Asked Questions
Can My Spouse Claim Part of My Business in a Florida Divorce?
They can claim part of its value, even if the business is in your name alone. The business itself may be separate property if you owned it before marriage, but the increase in its value during the marriage, especially if it came from your work (active appreciation), is generally marital and subject to division. A prenup is how you keep the business, and its growth, on the separate side of the line.
What Happens to My Business if I Die Without a Prenup?
Your surviving spouse can claim about 30% of your estate (the elective share), and the business is part of that estate. That can force a sale, a buyout, or hand a co-ownership stake to a spouse who has no role in the company, next to your partners or your children. A prenup that waives or limits those rights, coordinated with a buy-sell and your succession plan, prevents it.
How Does a Prenup Work With a Buy-Sell and Succession Plan?
They work as a set. The prenup keeps the interest separate and waives the spousal claims; the buy-sell controls what happens to the interest on death, disability, or divorce; and your trust or will routes ownership to the people you choose. Drafted together, they keep the company out of both divorce court and probate. Drafted piecemeal, they contradict each other.
I Already Own the Business and I’m Married. Too Late?
No. A postnuptial agreement can do the same job after the wedding, and it is often prompted by exactly this: the business grew, and you want to protect it and your partners. With full disclosure and independent counsel, it is enforceable.
