Does the child need to change his social security card if he has changed his name?

Legal analysis: it needs to be rewritten. You should take the original of your child's existing household registration book and fill out the change form at the liability insurance institution in your jurisdiction. If it is commercial insurance, it should be kept in the insurance company that buys insurance. You can contact the salesman who insured you at that time or go to the customer service front desk of the insurance company in your area to make changes (you need to bring your household registration book, applicant and insured ID card).
