How can I go and get my stepfather 2 adopt me my real father never been around I want my stepfather to be my dad I want his last name

You tell him that you would want him to adopt you. Step parent adoption is a fairly easy process particularly in cases where one biological parent does not have a relationship.

Have you spoken to your parents about it?

We have been talking about it for a long time just don't know what to do

When I turn 18 could I change my last name 2 y stepfather name

Yes - what State?

You don't/can't do anything. If your stepfather wants to adopt you he must file the appropriate legal papers. How old are you?

This should be combined with your other thread - https://www.askmehelpdesk.com/adoption/iwantmydadsobadwhat-do-do-408638.html#post2045936

The first step would be for your parents to contact a local lawyer.
