A uniform transfer to minors account, or UTMA, is a way that grandparents can put money away for their grandchildren. Sometimes called custodial accounts, UTMA accounts generally stay under the control of an adult custodian until the child reaches the age of majority.
Of course, you will no longer have access to these funds since you will not be the account owner, but for many grandparents that is an entirely acceptable consequence. To make contributions to an account owned by someone else you will need to know the account number and indicate that number on your check.
