My question involves adoption law for the State of: Kentucky

I am involved in an ongoing TPR/stepparent adoption case against my child's biological father. We have a court date set next month for a final hearing on the case. Here's my question: what happens if he does not show up for the hearing? He was in federal prison at the time when I began this case, and because of that, had a GAL appointed to represent him. He refused to cooperate and voluntarily sign the TPR papers, and would not work with the GAL on anything else. After being released from prison appx 6 months ago, he did not attend the first scheduled hearing, has had no contact with his GAL, and refused to have anything to do with the social services worker who contacted him for an interview regarding the case.
To summarize: he doesn't want to cooperate with anything involving this case, yet he won't voluntarily sign. The grounds for us seeking the TPR are abandonment (before his 2 year incarceration, he hadn't contacted my son in over a year), failure to provide support (he has never had a job and only ever given me child support one time in six years...twenty dollars.), has been found by the same court to be a habitual drug dealer/user, and hasn't in the last three years tried to have anything to do with this child. So if he just doesn't show up (again) for court, what happens? Will we have to keep rescheduling until he does show up? Or go on without him?
