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.
Another approach for parents and grandparents may be to combine the features of custodial accounts and 529 college savings plans. For example, by placing a 529 plan within a custodial account, the parent or grandparent can retain control until the student becomes of age (generally 18 to 21, but varies by state). After that, the student would have control, but must use the money for college expenses or pay a penalty.
