The Short Answer

Usually yes—in Florida, a joint bank account is generally presumed to pass to the surviving co-owner at death (so the survivor can typically access the funds), unless the account paperwork shows a different intent. A separate business account titled only in the deceased person’s name is usually a probate asset, meaning the bank commonly will not allow access until a court-appointed personal representative has authority.

What Florida Law Says

Florida treats many bank accounts as “non-probate” transfers when they are titled with survivorship rights. That means the money can pass by operation of the account contract rather than through the will or probate court. But the exact result depends on the account’s signature card/deposit agreement and how the account is titled.

The Statute

The primary law governing survivorship for bank accounts titled in two or more names is Fla. Stat. § 655.79.

This statute creates a presumption that, unless the account contract says otherwise, when one co-owner dies, the surviving co-owner(s) receive the deceased person’s rights in the account (and spouses are generally treated as holding the account as tenants by the entirety unless specified otherwise).

Relatedly, Florida also recognizes pay-on-death (POD) and certain multiple-party account rules that can cause funds to pass to a survivor/beneficiary outside probate. See generally Fla. Stat. § 655.82.

What that means for your two accounts:

• Joint personal account: If it is truly a joint account with survivorship (which is commonly presumed under Florida law), the surviving co-owner can typically access funds after death. That access is not the same thing as “permission to spend however they want,” because disputes can arise if other heirs claim the account was set up for convenience or there was undue influence.
• Business account in decedent’s name only: If the account is titled solely to the deceased individual (not a separate legal entity and no payable-on-death or joint owner), it is typically treated as an estate asset. Banks commonly require probate authority (letters of administration) before releasing funds.

Why You Should Speak with an Attorney

Even when the survivorship rule seems straightforward, applying it safely to real-life bill-paying and business operations can get complicated fast. Legal outcomes often depend on:

• Strict Deadlines: Estate and creditor issues can move quickly, and delays can create avoidable penalties, lapsed insurance, or business interruptions.
• Burden of Proof: The survivorship presumption in § 655.79 can be challenged (for example, with allegations of undue influence, fraud, or clear and convincing evidence of a different intent). That can turn “using the joint account to pay bills” into a contested probate dispute.
• Exceptions and Practical Bank Rules: Even if the law supports survivorship, banks often freeze or restrict accounts when they learn of a death until they review documentation. And if the “business account” is tied to an LLC/corporation or has authorized signers, the answer can change based on entity documents and bank resolutions.

Using funds the wrong way—especially from an account that should be part of the estate—can expose a family member or co-owner to claims from heirs, business partners, or creditors. A Florida probate attorney can quickly determine which accounts are non-probate, which require court authority, and how to reduce the risk of later litigation.
