:
Q. Can two people open an account for the same student?
A. Yes. Different account owners can open an account for the same beneficiary (student). So, for example, a parent and a grandparent can both open separate accounts for the same student. Whoever is listed as the account owner, controls the account.
Anyone can make contributions to an account; however, only the account owner can authorize a withdrawal, even if someone else has made contributions to the account.
The same account owner cannot open multiple accounts for the same beneficiary The account owner may, however, select different investment options for the same beneficiary.
