Commingling: How Mixing Assets Can Change Everything in a Florida Divorce
May 23, 2025 By Michael P. Sampson Sampson Collaborative Law You saved money before getting married. You fell in love and tied the knot without a prenup. Now, your marriage is falling apart. You’re thinking about divorce and discover that your savings might be split. Why? You mixed your pre-marriage money with money earned during the marriage. In Florida, this mixing—called commingling—can turn your separate property into shared property. It can change how your assets are divided in a divorce. Pour cream (the money earned during marriage) into a cup of steaming black coffee (your premarital savings). The now creamy coffee has changed. Irreversibly. Once mixed, the coffee changes forever. In a divorce, commingled assets work the same way. This guide explains commingling, how it affects your assets, and ways to keep your separate property safe. What Are Marital and Nonmarital Assets in Florida? In a Florida divorce, assets are split into two types: Timing Matters Unless you have a written agreement that says otherwise, asset status is determined on the date of filing for divorce, not on the date of separation (Yon v. Yon, 286 So. 3d 322, (Fla. 1st DCA 2019)); section 61.075(7), Florida Statutes. So, if you separate but don’t file for years, changes in asset status during that gap count. Valuing assets is a different matter from identifying them as nonmarital or marital. Courts may choose valuation dates for an asset other than the date of filing, however, when equity and evidence warrant. Section 61.075(7), Florida Statutes. Where the increase in value of a property or continued ownership of property is solely due to the work or efforts of the owner spouse, use of the separation date is mandated. Norwood v. Anapol-Norwood, 931 So. 2d 951 (Fla. 3d DCA 2006); Silva v. Claffey, Case No. 4D2024-0269 (Fla. 4th DCA Feb 05, 2025). Cf. Frazier v. Dodd, Case No. 5D2022-2478 (Fla. 5th DCA Mar 21, 2025) Knowing what counts as separate property is the first step to protect your money, especially inheritances or pre-marriage savings. Commingling: When Nonmarital Assets Become Marital Commingling happens when you mix separate assets with marital ones. This makes the separate part lose its identity. You can’t unmix cream from coffee. In Florida, this mixing makes the asset shared, and the court can divide it as a marital asset. Dravis v. Dravis, 170 So. 3d 849 (Fla. 2d DCA 2015). Real-Life Examples: Depositing your paycheck into a pre-marriage account (Distefano v. Distefano, 253 So. 3d 1178 (Fla. 2d DCA 2018)) or moving separate funds into a joint account for shared expenses (Knecht v. Palmer, 252 So. 3d 842 (Fla. 5th DCA 2018)) causes commingling. In Sturms v. Sturms, 226 So. 3d 1004 (Fla. 1st DCA 2017)), money from selling drilling rights owned by the husband’s premarital business became marital when mixed with business funds earned during the marriage. Blending marital funds with separate funds can jeopardize their nonmarital character. Did You Unintentionally Give Your Spouse Half Your Separate Assets? Commingling assets doesn’t just make them marital – it can also create a legal presumption you meant to give half to your spouse. Presumption of Gift: Mixing separate funds with funds in a joint account shows you intended a give half to your spouse. Link v. Link, 897 So. 2d 533 (Fla. 5th DCA 2005); Spielberger v. Spielberger, 712 So. 2d 835, 1998). In Link v. Link, a wife’s funds from life insurance proceeds deposited into a joint account were presumed a gift, and she couldn’t prove otherwise. Proving It Wasn’t a Gift: You must prove you intended no gift, which is hard once money gets mixed. Woodard v. Woodard, 634 So. 2d 782 (Fla. 5th DCA 1994). No Mixing, No Gift: If you keep funds separate, the court won’t presume a gift. Your spouse must prove you meant to share the funds. Grieco v. Grieco, 917 So. 2d 1052 (Fla. 2d DCA 2006). In Rogers v. Rogers, 351 So. 3d 1230 (Fla. 2d DCA 2022), the court saw no proof a joint account was just for convenience, so the trust money was considered a gift, making a boat purchased with such money marital. Joint accounts are risky. Keep separate funds in your own account to avoid sharing them by mistake. Nonmarital Assets That Stay Separate Some assets can stay separate if you’re careful. Not all assets are vulnerable to commingling. Accounts Kept Separate: Accounts funded only with separate funds, even if opened during marriage, stay separate. Street v. Street, 303 So. 2d 1253 (Fla. 2d DCA 2020). Stocks and Investments: Stocks or investments you had before marriage stay separate unless commingled or they grow with marital contributions or effort. Farrior v. Farrior, 736 So. 2d 1177 (Fla. 1999); Abdnour v. Abdnour, 19 So. 3d 357 (Fla. 2d DCA 2009). Inherited Assets and Proceeds: Assets you inherit, including money from selling those assets, stay separate if you don’t commingle them. Rivera v. Rivera, Case No. 3D22-1914 (Fla. 3d DCA 2023). In Rivera, money from selling an inherited house, used to buy a home for the husband’s mother and a car, stayed separate because he hadn’t commingled the proceeds with marital funds. Passive Appreciation: Appreciation of nonmarital assets remains nonmarital unless marital efforts or funds enhance the value. Doerr v. Doerr, 751 So. 2d 154 (Fla. 2d DCA 2000). However, Knecht v. Palmer, 252 So. 3d 842 (Fla. 5th DCA 2018) found that appreciation of a nonmarital home became marital due to commingled funds used for remodeling, though the court made an unequal distribution to adjust to achieve equity. Houses, inheritances, and some investments can stay separate, but don’t mix them with shared funds.
