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.
A custodian is legally responsible for ensuring that an item or person is safe and secure. In investment terms, a custodian is the financial services company that maintains electronic records of financial assets or has physical possession of specific securities. The custodian's client may be another institution, such as a mutual fund, a corporation, or an individual. For example, with an individual retirement account (IRA), the custodian is the bank, brokerage firm, or other financial services company that holds your account.
