I would think that the answer to this is going to depend on bank policy, which may or may not be what you want to hear. In my opinion, if the account was set up in an 'OR' situation, then either person could cash in the account. If that had happened in my bank, we would have asked for the original CD. If the owner didn't have it with them, we would have asked for a 'lost affidavit' to be signed, which simply states that the CD is either lost or not available, the ID would have been verified of the accountholder, and the CD would have been cashed in. The fact that the child was a minor gives me some heartburn, because the account should have been set up to reflect that. If it had been set up that way, there is no way that the child would have been able to cash that in. It is strictly going to be a bank policy issue as to that, I think. Have you called the bank and spoken to the manager and asked for their policy on this, or at least an explanation?
