I have a step-son whom i have have raise since he was 6 moths old, i am no longer with his mother. I do however have a son with her. My step son is now 12 and i still treat him as if he was my own. i Know i have legal rights when it comes to my biological child with the mother. But what i want to know it what are my rights as far as my step-son, i don't what to change his last name from his real father's but i do want to add my last last name to his name. How and what do i have to do to make this happen. Any advise would be greatly taken
