I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear about your situation.
If you have the ability to take the paperwork to your son's father in jail, and he would sign them, that's actually the easiest way to do a termination of parental rights with a stepparent adoption. You are required to serve the father with notice of the lawsuit, if you wind up having to sue. Jails have specific procedures for doing this, so to start, call the jail and ask how you would serve process on a prisoner. They'll walk you through it.
Without the father's consent, you'd be filing a Petition for Termination of Parental Rights, explaining that the father has not seen the child in more than 2 years, that he's in jail and expected to be there for at least one year (if that's the case). The judge is more likely to terminate parental rights when you file the paperwork for the stepparent adoption at the same time. The process can be complicated, so it's a good idea to have a local attorney create the paperwork for you. The courts don't have free forms online for this. Another option is to check out websites such as www.legalzoom.com to see if they can help.
Since you and your son are residents of California, you can file the Petition there. You'd only be filing in Nevada if you wanted to modify the original custody order, but this is a different procedure.
