Custodial Accounts. A custodial account is a bank or other financial account that a person opens for the benefit of another person, called the beneficiary. The person who opens the account is often the custodian -- the person who manages the account -- although it's also possible to name a third party as custodian.
The custodian remains in place until he resigns or becomes incapacitated, or the beneficiary reaches the age of legal adulthood. Other people can contribute towards a minor's account, but they have no authority over how the funds are managed once they are deposited.
