Hence, no crime.
In Texas, a minor can be the sole owner of a bank account. Parents can have a veto power over children's accounts if they go through certain letter-writing steps -- but they have to know about the account first. For information see --

From the article:
Minors Can Have Deposit Accounts in Texas
In Texas, the law permits minors to open bank accounts and be the sole owner of the account. According to Texas Finance Code § 34.305, the disability of being a minor is waived for the purposes of contracting with the bank. This means that minors can enter into contracts with banks to open accounts without requiring parental or guardian approval. However, the contract is voidable if the minor disaffirms the contract within a reasonable amount of time.
Banks May Have Other Requirements
It is important to note that some banks may have additional requirements or restrictions when it comes to minors opening accounts. For instance, they may limit the types of transactions, require parental approval for specific services, or request a parent to be a joint account holder. To ensure that the account is appropriate for their child’s needs and financial goals, parents and guardians should discuss these restrictions with the bank and their child.
Parents Have Veto Power
Parents or guardians still have veto power over the minor’s account to ensure that their interests are protected. They can restrict the minor’s ability to control, transfer, draft, or make a withdrawal from the account by writing a letter to the bank. This provides parents and guardians with a level of control over the account while allowing children to learn about financial independence and management.
