It is one of the most common things we hear from people getting ready to sign a prenup: “I bought the house before we got married, so it stays my house.” That is partly true. It is also the place where a lot of couples get surprised years later, because owning the house and owning all of its value are not the same thing.

Does a house I bought before marriage stay mine in Florida?

Yes, in the sense that it stays titled in your name. Under Florida’s equitable distribution statute, section 61.075, Florida Statutes, property you owned before the marriage starts out as nonmarital. You keep the right to sell it, refinance it or borrow against it.

Who owns the house and who gets its value in a divorce are two different questions. Title answers the first one. The second one depends on what happens to the house, and the money behind it, after the wedding.

Can my spouse get part of my house’s equity in a Florida divorce?

Yes, they can. Florida law treats the increase in value of a nonmarital asset as marital when it comes from marital money or from either spouse’s work during the marriage. Paychecks earned during the marriage are generally marital money, even when they go into an account in only your name.

So if the house becomes your marital home and the mortgage is paid from your earnings during the marriage, the principal paid down during the marriage can be marital. In many cases a share of the market appreciation can be marital too, because marital money helped carry the property. Renovations paid with marital funds, or real work either spouse puts into the house, can add to the marital share.

What else can turn a premarital house into marital property?

A few common moves can change the picture, often without anyone realizing it at the time:

• Adding your spouse to the deed. Florida presumes that real property held as tenants by the entireties is marital, even if one spouse bought it before the marriage.
• Refinancing together. A joint refinance or home equity loan can tie marital debt and marital money to the property.
• Mixing the money. If you sell the house and the proceeds land in a joint account, or go toward a new home bought together, it can become very hard to trace what was originally yours.

None of these is wrong. They just need to be decisions you make on purpose, with the consequences spelled out.

How can a prenup protect a house I already own?

Florida’s Uniform Premarital Agreement Act, section 61.079, Florida Statutes, lets couples agree in advance on their rights in property, including how it is treated if the marriage ends. For a premarital home, a well-drafted prenup can spell out:

• Whether the house and all of its future equity stay nonmarital, no matter whose money pays the mortgage.
• Whether appreciation during the marriage is shared, and how it is measured.
• Whether your spouse gets credit or reimbursement for what they put into the mortgage, taxes, insurance or improvements.
• What happens if you sell the house and buy another one, or refinance or add your spouse to the deed later.
• How the house is handled at death. Florida gives a surviving spouse rights in a homestead, and a premarital agreement can address those rights.

Is it fair to my spouse if all the equity stays mine?

It can be, but think through both sides. If the prenup says every dollar of equity stays yours, then a spouse who has helped pay the mortgage, often for years, walks away with no credit for it if the marriage ends. Some couples want exactly that. Others decide a reimbursement or a shared-appreciation clause is fairer.

Here is a simple example. One partner owns a condo before the wedding. After the marriage, the other partner pays half the mortgage every month for ten years. A prenup that keeps all the equity nonmarital means those payments come back to the paying spouse as nothing. A prenup that credits their share of principal paydown treats them very differently. Neither choice is right or wrong. What matters is that you both choose it knowing what it means.

What makes a Florida prenup hold up?

Under section 61.079, a premarital agreement must be in writing and signed by both parties, and it takes effect when you marry. A court may refuse to enforce it if a party did not sign voluntarily, if it was the product of fraud, duress, coercion or overreaching, or if it was unconscionable when signed and the other party did not get fair and reasonable financial disclosure.

In practice, that means exchanging full financial disclosure, signing well before the wedding rather than the week of it, and giving each person a real chance to have their own attorney review the agreement.

Questions to bring to your attorney

Is the house going to be our marital home? Whose income will pay the mortgage, taxes and insurance after the wedding? Do we want appreciation shared, kept separate or measured by a formula? Should the other spouse get credit for what they contribute? What happens if we sell, refinance or buy a new home together? How do we want the house handled if one of us dies?

Frequently asked questions

Is a house bought before marriage marital property in Florida?

No, it starts as nonmarital property. But the increase in its value during the marriage can be marital when marital money, like either spouse’s earnings, pays down the mortgage or improves the home, or when either spouse’s work during the marriage adds to its value.

Does my spouse get half my house if we divorce in Florida?

Not automatically. Your premarital equity generally stays yours. What may be divided is the marital portion, such as mortgage principal paid down with marital funds and, in many cases, part of the appreciation. A prenup can set those rules in advance.

Can a prenup keep my house and its appreciation separate?

Yes. Florida’s Uniform Premarital Agreement Act lets couples agree on how property and its appreciation will be treated. The agreement should be in writing, signed by both of you, and backed by full financial disclosure.

What happens if I add my spouse to the deed after we marry?

Florida presumes that real property held as tenants by the entireties is marital, even if one spouse bought it before the marriage. Talk with an attorney before changing the deed, and make sure your prenup says what happens if you do.
