How to Protect Separate Property if You’re Considering Divorce in FL

You brought assets into the marriage. Maybe an inheritance, a business you built before the wedding, or real estate you purchased with your own funds. Now that divorce is on the horizon, you need to protect separate property in your FL divorce before those assets get pulled into equitable distribution.

Florida law distinguishes between marital and nonmarital property. But the line between the two isn’t always clear, especially after years of marriage where finances have overlapped. Taking the right steps now can determine whether your separate property stays yours.

What Qualifies as Separate (Nonmarital) Property in Florida?

Under Florida Statute § 61.075, nonmarital assets include:

• Assets acquired before the marriage. Property, bank accounts, investments, or businesses you owned prior to the wedding.
• Inheritances received individually. Even if received during the marriage, an inheritance left specifically to one spouse remains nonmarital unless it’s been commingled.
• Gifts from third parties to one spouse. A gift from your parents to you (not to both of you) is nonmarital property.
• Income derived from nonmarital assets. If your premarital investment generates income and you kept that income separate, it may remain nonmarital.
• Assets excluded by a valid prenuptial or postnuptial agreement.

The burden of proving an asset is nonmarital falls on the spouse claiming it. This is why documentation and asset separation are critical.

How Separate Property Becomes Marital Property

The biggest risk to your separate property is commingling.

When you mix nonmarital assets with marital funds, the nonmarital character of those assets can be lost.

Common ways commingling happens:

• Depositing an inheritance into a joint bank account. Once inherited funds are mixed with marital money, tracing them back becomes difficult and sometimes impossible.
• Using marital income to improve nonmarital property. If you owned a home before marriage but used joint funds for renovations, the appreciation attributable to those improvements may become marital.
• Adding your spouse’s name to a premarital asset. Putting your spouse on the title of your premarital home or business interest can convert it to marital property or create a presumption of gift.
• Using a premarital business to support the family. If marital labor and funds contributed to the growth of a premarital business, the increase in value during the marriage may be marital.

Steps to Protect Separate Property Before Filing

If you’re considering divorce, take these steps now to protect separate property in your FL divorce:

1. Document the origin of every nonmarital asset.

Gather records proving when and how you acquired each asset. This includes purchase records, inheritance documentation, gift letters, premarital bank statements, and title documents showing ownership before the marriage date.

2. Maintain separate accounts for nonmarital funds.

If you haven’t already, stop depositing nonmarital income or assets into joint accounts. Open an individual account for any inheritance, gift, or premarital asset income. Do not use this account for household expenses.

3. Get current valuations.

Obtain appraisals for real estate, business interests, and other significant assets. Establishing current value creates a baseline for equitable distribution.

If you can show what an asset was worth at the time of marriage versus now, you can argue that only the marital portion of appreciation is subject to division.

4. Trace commingled funds.

If your separate property has already been mixed with marital assets, hire a forensic accountant to trace the nonmarital funds. Florida courts will recognize the nonmarital character of traced assets if the tracing is clear and well-documented.

The Florida Bar has addressed how courts handle commingled funds, and the key takeaway is that tracing must be specific and supported by records.

5. Do not transfer, hide, or dissipate assets.

Moving money, selling property below market value, or giving away assets to prevent your spouse from receiving them can backfire.

Under § 61.075, courts can consider intentional dissipation of marital assets and may award a larger share to the other spouse as a result.

Understanding Active vs. Passive Appreciation

Even if you successfully prove an asset is nonmarital, part of its value may still be subject to division.

Florida courts distinguish between two types of appreciation:

• Passive appreciation is growth that happens without effort from either spouse, like market-driven increases in a stock portfolio or real estate values rising with the housing market. Passive appreciation on a nonmarital asset remains nonmarital.
• Active appreciation results from the labor, effort, or financial contributions of either spouse during the marriage.

If you or your spouse actively managed, improved, or grew a nonmarital asset using marital time or resources, the increase in value attributable to that effort is marital property subject to equitable distribution.

This distinction frequently comes up with premarital businesses.

A business worth $1 million at the time of marriage that grows to $3 million may owe much of that growth to the owner-spouse’s labor during the marriage.

The $2 million increase could be classified as marital. Proving how much of the growth was passive (market conditions, industry trends) versus active (the spouse’s daily management) requires forensic accounting and sometimes competing valuations.

Consider a Postnuptial Agreement

If you’re not ready to file for divorce but want to formalize protections now, a postnuptial agreement can define which assets remain separate.

Under Florida’s 2024 amendments to § 61.075 (HB 521), interspousal gifts of real property must now be agreed upon in writing.

A postnuptial agreement provides a written framework that courts can enforce, as long as it meets the same voluntariness and disclosure standards as a prenup.

What If Your Spouse Claims Your Separate Property Is Marital?

Expect this to happen in a contested divorce. Your spouse’s attorney will argue that nonmarital assets became marital through commingling, joint use, or your spouse’s contributions to the asset’s value.

Your defense depends on:

• Clear documentation of the asset’s nonmarital origin
• Evidence of separation between marital and nonmarital funds
• Expert testimony from a forensic accountant who can trace the funds
• Title records showing the asset remained in your name alone

The stronger your paper trail, the harder it is for your spouse to reclassify your separate property as marital.

Protecting What You Brought Into the Marriage

Florida law recognizes your right to keep what’s yours. But that protection only works if you can prove the asset’s nonmarital character with documentation. The time to organize that evidence is before you file, not after your spouse’s attorney starts challenging every account.
