Have you legally changed your son's name?
Yes, his last name has changed.
Is your son currently working?
No, he doesn't work.
You are in need of a new card due to a legal name change. Is that correct?
Yes, I'd like to receive a new card, but is it really necessary?
Yes, because having the wrong name on his card may delay you are your son's tax refund in the future.
I know I shouldn't have waited so long, but my son's name was changed 5 years ago. Will this be an issue in verifying his identity?
No, there will not be an issue as long as you have an identity document with your son's prior name on it.
