I didn't actually attend either of my girls final hearings. First one, it wasn't safe..huge security issue. The second time, DD2's mum contested, and it just didn't feel right for me to be there..not because there was a security issue, there isn't, but because it was her last chance to fight for DD and though it was certain she wouldn't win, it felt wrong for me to be there. I couldn't bear to witness her grief knowing that I was involved in it. I also felt she might be embarrassed if i was there, and it isn't something i would want to relate to DD2 were she to ask in later years.
Both times, just had the clebration hearing (I assume that's the same thing as pronouncement)
With DS, I did attend. His mum was in agreement with adoption this time (he is DD2 bio sib) and wouldn't be there, and I wanted to find out what actually happened at the hearing...nothing much is the answer!! Very quick and official
I think you have to go with your gut. The final hearing IME is nothing very special in practice...the balloons and presents are for the celebration hearing. If your DS biological family are a risk, it probably isn't sensible to go.
Also, if they are planning to turn up, and they don't want to meet you at all, I wouldn't go. It will be a day of great grief for them almost certainly, and I doubt if it were me i'd really want the a-family seeing that.
For me, the celebration hearing was the special time...kids, me, photos, smiling judge, a couple of balloons..that was the special hearing for me
