UFC PS4/Origin - minimum age requirement

[ghlong2496]

My son gets an error message regarding not meeting the minimum age requirement for an Origin account.  I found on the Battlefield 4 forum a way around that, but was wondering about the Origin age requirement.  Their TOS says must be 18 or have gone over the terms with a parent, but I cannot find anywhere to confirm that he has my permission to set up an account.  How can I do that for him?
