I am not 100% sure how one goes underground properly in the current system. I mean, you need the forms and thus need to present at a hospital to get them one way or another. So obviously you'd be going in saying you freebirthed or accidental home birthed. Just would be fair obvious you are telling porkies I guess.

I would go to a hospital. As much as I hate the environment, I would not ask anyone to put their career - and possibly freedom - on the line for me.
