What If We Disagree on What’s Marital vs. Separate Property in FL?

One of you says the beach house is separate property because you bought it before the marriage. The other says it’s marital because joint funds paid the mortgage for 15 years. A marital vs. separate property dispute like this is one of the most contested issues in Florida divorce.

Florida law draws a clear line between marital and nonmarital property. But after years of shared finances, that line often gets blurred. Here’s how the classification process works and what happens when both sides disagree.

How Florida Defines Marital vs. Nonmarital Property

Florida Statute § 61.075 classifies every asset and liability as either marital or nonmarital. The court must complete this classification before it can divide anything.

Marital assets include:

• Assets acquired during the marriage by either spouse, individually or jointly
• The enhancement in value and appreciation of nonmarital assets resulting from marital labor or marital funds
• Interspousal gifts during the marriage
• All vested and nonvested benefits, rights, and funds accrued during the marriage in retirement, pension, profit-sharing, annuity, deferred compensation, and insurance plans
• Real property held as tenants by the entireties, which is presumed marital regardless of when it was acquired

Nonmarital assets include:

• Assets acquired before the marriage
• Inheritances received individually during the marriage
• Gifts from third parties to one spouse
• Income from nonmarital assets (if kept separate)
• Assets defined as nonmarital by a valid written agreement

Where Marital vs. Separate Property Disputes Get Complicated

Disagreements rarely involve straightforward cases. The fights happen in the gray areas:

1. Commingled assets

Your spouse inherited $200,000 and deposited it into a joint account.

Over the years, marital deposits and withdrawals mixed with those funds. Your spouse says the inheritance is still nonmarital. You say it became marital through commingling.

The court will look at whether the nonmarital funds can be traced back to their original source.

2. Active vs. passive appreciation

Your spouse owned a business before marriage worth $500,000. During 12 years of marriage, it grew to $2 million.

The question: did that growth result from market conditions (passive, nonmarital) or from your spouse’s labor and marital resources (active, marital)?

Courts treat active appreciation as marital property subject to distribution.

3. Marital contributions to nonmarital property

You both paid the mortgage on a home your spouse owned before marriage. The home’s value increased by $300,000.

That appreciation attributable to marital funds or labor is marital property, even though the underlying asset is nonmarital.

4. Title doesn’t control

Whose name is on the account or deed doesn’t determine whether the asset is marital or nonmarital.

An asset titled solely in one spouse’s name can still be marital if it was acquired during the marriage or enhanced with marital resources.

How the Court Resolves a Marital vs. Separate Property Dispute

When spouses disagree on classification, the court follows a structured process:

1. The claiming spouse bears the burden of proof.

If you claim an asset is nonmarital, you must prove it. If you can’t produce documentation showing the asset’s premarital origin or its separate character, the court may classify it as marital.

2. Tracing determines the outcome.

For commingled assets, the court relies on forensic accounting to trace funds to their nonmarital source.

If the tracing is clear and well-documented, the nonmarital portion can be separated from the marital portion.

If funds are too intertwined to trace, the entire asset may be treated as marital.

3. Expert testimony matters.

Business valuators, forensic accountants, and real estate appraisers often testify about whether appreciation was active or passive, whether funds were commingled, and what the marital vs. nonmarital portions of an asset are worth.

4. The court classifies, then values, then distributes.

This is a three-step process under Florida law. Classification disputes must be resolved before the court can determine how to divide the marital estate.

2024 Changes That Affect Property Classification Disputes

Florida’s 2024 amendments to § 61.075 under HB 521 (effective July 1, 2024) made several changes that directly affect how marital vs. separate property disputes play out:

• Special equity claims are formally eliminated. Florida abolished the special equity doctrine in 2008, and HB 521 codified that all such claims must now be asserted as arguments for unequal distribution under § 61.075(1) or as enhancement and appreciation claims.

If your spouse tries to use a special equity theory to claim a share of your nonmarital asset, that argument no longer has a legal basis in Florida.

• Interspousal gifts of real property must be in writing. If your spouse claims you gifted them an interest in your premarital home, that gift must now be documented in writing under Florida Statute § 689.01.

This provides stronger protection for property owners whose spouses claim an oral gift was made.

• Closely held business interests have specific valuation standards. The amendments added detailed provisions for how courts should value business interests, which affects disputes over whether business growth during the marriage was active or passive.

These changes shift the landscape for classification disputes filed after July 1, 2024.

If your divorce involves contested property classification, the strategy needs to account for the current statutory framework.

The Cost of Not Raising Classification Issues Early

If you don’t raise a classification dispute properly and early in the case, you risk waiving it.

Courts expect parties to identify contested assets during mandatory disclosure and discovery. Waiting until trial to argue that an asset your spouse disclosed as marital is actually nonmarital puts you at a significant disadvantage.

Your attorney should identify every potential classification issue during the initial review of financial disclosures and build the factual record during discovery, not after it closes.

What Evidence Do You Need to Win a Classification Dispute?

The outcome depends on documentation. The spouse with better records usually prevails.

• Premarital bank and investment statements showing account balances at the time of marriage
• Inheritance documentation: will, probate records, or trust distribution letters showing the asset was left to one spouse individually
• Title records showing when the property was acquired and in whose name
• Transaction records showing deposits, withdrawals, and transfers that demonstrate whether nonmarital funds were kept separate or commingled
• Business financial records documenting value at the time of marriage vs. current value, and whether marital resources contributed to growth
• Tax returns reflecting income sources and how funds were reported during the marriage
