Once legally free how long does it take?

I guess it all depends on the state, county, and the sw. Our little guy was placed with us on 10/03, TPR 10/04, he became legally free (after appeal) 11/05 and we hope to finalize 2/06. Our sw started all the paper work before he was legally free, so it should not be long. I can't wait till he is ours.
