Custodial Account

An account opened on the behalf of a minor by an adult who acts as custodian. The custodian is usually one of the child's parents--both parents cannot be custodian. This type of account is opened because minors cannot enter into contracts. Thus, they cannot make securities transactions for themselves. Any assets placed into a custodial account are irrevocable. Once the minor is of majority (usually 18, but some states are 21), they may do what they please with the assets.
