What Is a Cohabitation Agreement and Do We Need One?
If you and your partner live together but are not married, you may not have any legal rights or protections in the event of a breakup or unexpected life event. A cohabitation agreement is a written contract that outlines how you want to handle shared property, finances, and other personal matters.

Why This Agreement Matters in Florida
In Florida, unmarried couples do not have automatic rights to each other’s property or support. Even if you have been living together for years, the law does not treat you as a married couple. If your name is not on a deed, a bank account, or a loan, you may have no legal claim to that asset. A cohabitation agreement gives both partners the chance to define their intentions before a dispute arises.
What You Can Include
A cohabitation agreement can address how you share living expenses, who pays for what, and how to divide joint purchases if you separate. You can also outline how you want to handle joint bank accounts, retirement savings, or real estate. If one of you owns a home that you both live in, the agreement can clarify whether the other person will have any interest in that property. You can also include terms related to support, such as agreeing to temporary financial help if the relationship ends.
While Florida law does not allow parents to permanently decide custody or child support in advance, you can include your shared understanding about how you plan to raise your children. A judge is not required to follow those terms, but they may take them into account if the arrangement has been working well over time.
Planning for the Future
You can also include what happens if you decide to marry later. Some couples choose to incorporate parts of their cohabitation agreement into a future prenuptial agreement. Others may agree to keep certain property separate even after marriage. A cohabitation agreement gives you the flexibility to address both current and future possibilities.
