Thanks for the response. This answers my question. I thought the minor did not meet the customer definition in Reg P until they reach adulthood, but needed confirmation.
You have both Randy Carey and me confused with your question and explanation.
It is always helpful to describe the scenario completely to avoid leaving possible responders in the dark. We know the kid was about two years old when the account was opened. And you want to change the account type because the kid is approaching his 18th birthday, right? And you want to know whether you need to provide new account disclosures.
Is the account a joint account with a parent, or is the minor the only owner?
Is it a UTMA account with a custodian, or not?
