What happens after 12 months and CPS case is dismissed?

Interesting, as I was led to believe that they would not be able to get a TPR because she has worked her plan perfectly, except for these charges still pending. Bio mom's lawyer gave me the impression that they would not get TPR granted if it went to trial...but I do take what he says with a grain of salt. That's why I thought I would get more real-life accounts here. This is so confusing. CPS can't have an RU plan with the charges pending, the lawyer says they wouldn't have adequate grounds for TPR. This isn't technically true since I've read that the reasons they were removed are grounds, the bio dad was MIA and isn't working his plan now, and this isn't the first time CPS has removed them. I haven't a clue what may happen if the kids can't be returned to her and we refuse PMC (though we would adopt) and the case is dismissed. There HAS to be a plan for the judge at the trial, though. Maybe that's it, she will decide their fate. My personal stand is appeal for an extension so that the criminal case is taken care of and go from there. If not done in the time allowed, then TPR and we adopt. I've been told that this isn't likely as the judge doesn't grant extensions except in extreme cases. Why not try, though? This is taking place in Brazos Co.
