My question involves name change laws in the State of NYS
Well, my son full name is Joseph Piter dos Santos. He is 4 now. On his brith certificate from New York has his last name as " Dos Santos". However, I would like to remove the "Dos" from his last name becoming then just "Santos". I could take it from the last name and put in the middle name so it will be Piter dos as middle name or just remove it. I just want his last name to be "Santos" and not "Dos Santos". How do I do that? Is that considered a name change or a mistake?
Thank you.
