What Is a Custodian?
Under Florida law, minors (children under 18) are legally incapacitated regarding major financial transactions. A 10-year-old cannot legally sign a contract, open a brokerage account, or sign a deed to sell a house. Therefore, if a minor inherits a massive life insurance payout or a piece of real estate, the law requires an adult to step in.
This adult is called a custodian. Appointed under the Florida Uniform Transfers to Minors Act (FUTMA), the custodian takes control of the child's custodial account. The child is the true owner of the money, but the custodian is the only person legally authorized to touch it.
The Custodian's Fiduciary Duty
Being a custodian is not a casual favor; it is a strict legal responsibility. The custodian owes a fiduciary duty to the child. This means the custodian must act with total financial loyalty.
The custodian is legally forbidden from using the child's money for their own personal benefit. They cannot use the child's inheritance to pay off their own mortgage or start a business. The funds can only be spent for the direct benefit of the minor (e.g., paying for private school, summer camp, or a first car). If a custodian steals or mismanages the money, the child can sue the custodian for damages when they grow up.
When Does the Custodian's Power End?
In Florida, a custodian's power over a standard FUTMA account has a strict expiration date. Usually, on the child's 21st birthday (or 18th, depending on how the account was structured), the custodianship automatically terminates. The 21-year-old gains absolute, unrestricted access to the money, and the custodian cannot stop them from spending it. Because of this, estate planning attorneys often recommend wealthy parents use a living trust rather than a custodian, as a trust can withhold the money until the child is 30 or older.
