I would go, if i were you.
With my first son, the foster worker never told me when court was, never informed me of anything. I showed up for a visit with a relative and she said "so court was today, they TPR'd " ...his case was very straightforward, bmom wasnt involved, the hearing probably took all of ten minutes. Essentially he was "abandoned"...so i probably didnt miss much, however i still wish i would have gone so that at least i would know what was said.
With my current FS...the trial for termination was scheduled for just a few months after he was placed with me. Normally, they wrap things up pretty quickly, they had scheduled two dates ten days apart, the second date was just in case they didnt finish on the first. Well, we had two dates in October, a couple in December, one in Feb and just finished last Tuesday!
Due to lots of issues like scheduling conflicts, judge reassigning a new lawyer for the dad, etc.
I was very nervous to go because i didnt know what to expect, but it was very very casual, not once did they start on time, ever...i just sat in the back and observed. The courtroom was VERY small. No one asked anything of me. On the last date, i brought some pics of the kids for the judge, but the clerk wouldnt take them, and said i could ask the judge if she wanted them, but there really wasnt a good time to do that.
I got alot of info i didnt have, and i really felt like i needed to be there to represent the kids...everyone had their own agenda but i just wanted to be the one there solely for them.
The judge ruled right after closing arguments. TPR'd all three parents. I felt really bad. i mean, i pretty much cried through her whole statement. The mom got up and walked out before she was finished and the dad argued with the judge during her ruling. It was ugly. It was awful. I mean...i was "happy" in the sense that meant i get another son (and hopefully, daughter)...but it was not a "happy joy joy" feeling at all. And i'm sooo glad i went because the judge made some very profound statements about the children that i want to write down and have for them in the future. They need to know WHY the judge ruled the way she did. And i'm glad i will be able to tell them, because i was there.
Good luck.
