Can you adopt a stepchild without the father knowing?

No — the biological father must be legally notified through service of process. This is a constitutional requirement to protect due process rights.

However, there are important distinctions:

If his location is known:

• He's served with adoption papers (by sheriff or process server)
• He has a set period to respond
• If he doesn't respond, the adoption proceeds without his consent

If his location is UNKNOWN:

• You can serve by publication — a legal notice in a newspaper
• This satisfies the legal requirement to notify
• He almost certainly won't see it, and the adoption proceeds
• This is very common and courts handle it routinely

If he was never on the birth certificate:

• His parental rights may be limited
• The court may require only reasonable effort to notify

Bottom line: You can't skip notification entirely, but when the father is absent and uninvolved, the notification requirement is a formality. Over 80% of our adoptions proceed without the father's consent.
