Short answer: In Florida, making an adult child a joint owner of a bank account can do more than give access. Under Fla. Stat. § 655.79, a joint account is presumed to pass to the surviving owner, and a will does not automatically override that result. A convenience account, POD designation, or durable power of attorney may better fit a parent’s goals.
Adding an adult child to a bank account may seem like a practical way to make life easier. Perhaps the parent is getting older and wants someone nearby who can pay bills, monitor transactions, or deal with the bank in an emergency. Maybe the child already helps manage household expenses, and adding their name to the account seems like a simple formality. The bank may offer a joint account, and the paperwork may take only a few minutes.
But in Florida, adding someone as a joint account owner can have consequences well beyond giving that person access to the money. Depending on how the account is established, the child may acquire survivorship rights that determine who receives the entire account when the parent dies. That result may be very different from what the parent intended.
What Happens to a Joint Bank Account When One Owner Dies?
Under Florida Statutes § 655.79, a deposit account held in the names of two or more people is generally presumed to provide a right of survivorship unless the account documents expressly provide otherwise. That means the surviving account owner ordinarily receives the remaining funds when another owner dies. The statute applies to accounts such as checking accounts, savings accounts, and certificates of deposit.
Consider a parent with three adult children whose will divides the estate equally among all three. Years earlier, however, the parent added one child to a substantial checking or savings account. If the account carries survivorship rights, the surviving joint owner may receive the entire balance directly.
The funds generally pass outside the probate estate by operation of the account’s ownership arrangement, and the will does not automatically override that result. For married couples, Florida law provides that an account in the names of a husband and wife shall be considered a tenancy by the entirety unless otherwise specified in writing, so the analysis for spouses can differ from that for a parent and adult child.
The language of the bank’s account agreement and signature card matters. So does the account holder’s actual intent.
What If the Parent Only Wanted Help Paying Bills?
A parent may have no intention of giving one child a larger inheritance. The child may have been added solely because they lived nearby, handled the household finances, or were available to help.
The statutory presumption can be challenged. Section 655.79(2) provides that it may be overcome only by proof of fraud or undue influence or clear and convincing proof of a contrary intent. But proving that intention after the parent has died can be difficult. The person whose intentions matter most is no longer available to explain what they wanted.
The surviving child may believe the account belongs entirely to them. The other children may insist that their parent intended the money to be divided equally. Bank records, statements by the deceased parent, and the circumstances of how the account was created and used may all become relevant. What began as a convenient way to pay household bills can become a dispute over a substantial portion of the family’s inheritance.
A Florida Court Has Already Addressed This Problem
The issue is more than hypothetical. In Larkins v. Mendez, 363 So. 3d 140 (Fla. 3d DCA 2023), the Third District Court of Appeal considered a dispute involving a father who had added one of his three sons to a bank account. The bank’s signature card identified the account as a multiple-party account with a right of survivorship.
After the father died, the son on the account claimed the funds belonged to him. The personal representative of the father’s estate challenged that claim, contending that the father had intended a convenience account. Part of the evidence for that came from one of the father’s other sons, who testified that his brother had been added to the account only to help their father pay bills and manage his finances. The probate court considered testimony from family members, records reflecting how the account had been used, and statements indicating that the father wanted the funds divided among his three sons. It concluded that the account had been intended as a convenience account rather than a true survivorship arrangement, and the appellate court affirmed, explaining that the statutory presumption of survivorship could be overcome by clear and convincing evidence of contrary intent.
The decision shows two things. First, Florida courts are not necessarily limited to the bank’s signature card when determining whether the statutory presumption has been overcome. Second, resolving the question may require extensive litigation. In Larkins, the probate court held a four-day bench trial before ruling on the account, something a parent who simply wanted help managing money probably would not anticipate.
Florida Has a Different Type of Account for Convenience
Under Florida Statutes § 655.80, a convenience account allows an individual to authorize another person to make deposits, withdraw funds, or write checks without making that person a joint owner. The statute distinguishes between the account’s principal, who remains the owner of the funds, and the person designated to act as an agent. The agent receives authority to conduct transactions for the principal’s benefit, but that authority does not make the agent the beneficial owner of the account.
The distinction is particularly useful when a parent wants an adult child to assist with banking but does not intend to alter the distribution of the estate. A properly established convenience account does not give the assisting child survivorship rights. Instead, the balance remains subject to the ownership and administration rules applicable to the principal.
Not every financial institution uses the same terminology or offers identical account options. The bank’s actual documentation should be reviewed to determine what type of account is being established. Simply telling a bank employee that an account is intended for convenience does not mean the paperwork creates the legal arrangement the customer expects.
What About a Payable-on-Death Account?
Another option is a payable-on-death (POD) designation, governed by Florida Statutes § 655.82. A POD account allows an account owner to designate one or more beneficiaries to receive the remaining funds after the death of the account’s owner or last surviving party. During the owner’s lifetime, the POD beneficiary has no present right to the funds.
For example, a parent could maintain an individually owned savings account while naming three children as POD beneficiaries. If those beneficiaries survive the parent, the funds ordinarily pass directly to them rather than through the parent’s will. Florida law provides that if two or more POD beneficiaries survive, the funds belong to them in equal and undivided shares. The practical advantage is that the account owner can establish who receives the money after death without giving those beneficiaries ownership rights while the owner is alive.
But a POD designation does not, by itself, authorize a child to pay the parent’s bills during the parent’s lifetime. That requires a separate source of authority. Beneficiary designations also need to be coordinated with the broader estate plan. A POD arrangement that made sense when it was established may no longer reflect the owner’s wishes after a marriage, divorce, death, or other significant family change.
Could a Durable Power of Attorney Be a Better Solution?
For many families, the real objective is to let someone handle financial transactions if help becomes necessary. A Florida durable power of attorney can address that concern without necessarily changing account ownership. Under Florida’s Power of Attorney Act, a principal may authorize an agent to conduct banking and other financial transactions within the authority granted by the document.
Florida law treats an agent acting under a power of attorney as a fiduciary. Under Florida Statutes § 709.2114, the agent must act within the authority granted, act in good faith, and generally act in the principal’s best interest. The statute also imposes recordkeeping obligations and requires the agent, when appropriate, to attempt to preserve the principal’s known estate plan. Those duties create a very different legal relationship from simply adding another person as a joint account holder.
A durable power of attorney may also provide broader assistance than a convenience account. An agent may need to communicate with financial institutions, manage investments, handle financial obligations, or address property and business matters beyond one checking account. The actual powers depend on the document, and Florida Statutes § 709.2202 imposes additional execution requirements for certain sensitive powers, including changing beneficiary designations and survivorship rights. A power of attorney should therefore be drafted with the individual’s broader financial circumstances in mind.
Can Adding a Child to an Account Create Problems While the Parent Is Alive?
Potentially. When someone becomes a joint account owner, the account arrangement may let that person withdraw money or conduct transactions without the other owner’s approval for each transaction. That creates obvious practical concerns if the relationship deteriorates or the child makes financial decisions the parent does not approve.
The child’s own finances can also create complications. For example, if the child becomes involved in a collection proceeding, creditors may examine accounts in which the child holds an ownership interest. Whether particular funds can be reached depends on the ownership arrangement, the source of the funds, and the applicable creditor-protection rules. Joint ownership does not automatically mean that every dollar in an account is legally available to satisfy the debts of either account holder. Still, having to prove who actually owns the funds may be an unnecessary complication. Similar concerns can arise during a divorce, bankruptcy, or other dispute involving the child.
These risks do not mean that joint accounts are inherently inappropriate. They are a reminder that granting ownership can have consequences beyond granting practical access.
How Does a Joint Account Affect the Rest of an Estate Plan?
Bank accounts are often overlooked when people prepare wills and trusts. A will may contain carefully drafted provisions on unequal distributions, specific gifts, or the treatment of beneficiaries, but account ownership arrangements may direct substantial assets outside those provisions.
Suppose a parent wants all three children to inherit equally. If one child receives a $150,000 joint bank account by survivorship while the rest of the probate estate is divided equally, the overall result may be quite different from what the parent intended. The same issue can arise when accounts have outdated POD beneficiaries, or when a revocable trust was created but account ownership and beneficiary designations were never coordinated with it, a problem discussed in what happens when a revocable trust is never funded.
An estate and succession plan should account for how property actually passes at death. That includes wills and trusts, but also jointly owned property, beneficiary designations, business interests, and other arrangements that may operate independently of the will. The documents need to produce the intended result when considered together.
Should You Remove a Child Who Is Already on Your Account?
Not necessarily. The first step is to determine what type of account exists, because an account that gives a child transaction authority may be structured differently from one that gives the child ownership and survivorship rights. The bank’s documents should be reviewed before assuming that adding a name created a particular legal result.
If the arrangement does not reflect the parent’s intentions, the available options may include changing the account ownership, establishing a convenience account, revising beneficiary designations, or using a durable power of attorney. The appropriate solution depends on the parent’s objectives, the bank’s policies, the existing ownership rights, and how the account fits into the estate plan.
Extra care is needed when the parent’s capacity is in question or when someone other than the parent seeks to make changes. An agent acting under a power of attorney cannot assume that general banking authority includes permission to change survivorship rights or beneficiary designations, because Florida law imposes particular requirements on those powers. Where substantial funds or disputed ownership interests are involved, modifying an existing account can require considerably more care than opening a new one.
The Account Should Reflect What You Actually Want
Adding an adult child to a bank account is often done for sensible reasons. Parents want assistance. Children want to help. Nobody necessarily expects the arrangement to create problems. But Florida law distinguishes between giving someone access to money, making that person an owner, and designating someone to receive the account after death. Those are different decisions with different consequences.
A joint account may be appropriate when the owner genuinely intends the other person to have ownership and survivorship rights. A convenience account, properly authorized agent, or POD designation may better serve a different objective. Before adding a child’s name to an account, it is worth asking what authority that person should have today and what should happen to the money after death. The answers may point to two different arrangements. And getting that distinction right in advance is considerably easier than asking a probate court to determine what the parent intended years later.
Frequently Asked Questions
If I add my adult child to my bank account, will the money go to them when I die? It may. Under Florida Statutes § 655.79, an account in the names of two or more people is presumed to give the surviving owner the remaining funds unless the account documents expressly provide otherwise. Those funds generally pass outside probate, and your will does not automatically override that result.
Can my child help pay my bills without becoming an owner of my account? Yes. Florida Statutes § 655.80 recognizes a convenience account, which lets you authorize another person to make deposits, withdraw funds, or write checks while you remain the owner of the funds. A durable power of attorney can also give an agent authority to handle banking and other financial transactions without necessarily changing account ownership.
What is the difference between a joint account and a payable-on-death account? A joint owner may be able to withdraw money or conduct transactions without your approval for each one, and may receive the account by survivorship. A payable-on-death beneficiary has no present right to the funds during your lifetime and receives the remaining funds only after the death of the owner or last surviving owner. A POD designation does not, by itself, allow a child to pay your bills.
My child is already on my account. Should I take them off? Not necessarily. The first step is to review the bank’s documents to determine what type of account actually exists. If the arrangement does not reflect your intentions, the options may include changing the account ownership, establishing a convenience account, revising beneficiary designations, or using a durable power of attorney.
