If there is not a concern regarding his current behavior or current drug use - you really have to weigh the realities of what may occur and if it is worth it. It probably is not worth the time, money or energy to attempt to force supervision.
Technically and legally, you win if that is all the order states. He tested positive, he goes back to supervised visitation.
In reality, if you try to force that issue, he is going to attempt to modify or clarify the decree, and, based on the...
You must get orders in place regarding the kids. Right now, if there are no orders, neither party has a superior right to the children. That means either one of you could withhold the kids, pick the kids up from school, without real consequence. The temporary orders referenced in the other answers give the rules for exchanges and possession.
If you truly believe the kids are in imminent danger, you need to file an ex-parte motion and get an ex-parte order. This is only good for 14 days,...
It really sounds like the ex is just bullying you. He is certainly able to get a DNA test, but most courts will wait until the child is born to avoid any risk to the child. The ex will also need to file a paternity action unless there is some court proceeding already in progress.
His lawyer can contact you but you do not have to speak with the lawyer. When the ex won't give you the information on the lawyer, either he doesn't have one (likely) or really is being difficult, which means you...
1) get an agreement to reset the hearing (not likely).
2) file a motion for continuance with the court and set it for hearing. Send a copy to the other attorney and then you have to go to court at the hearing for the motion for continuance (before October 5) and ask the Judge to move it.
You cannot file for violations of an order when you do not know what that order actually says. Get a copy of the order from the district court. Dallas allows most to be obtained online if you have all of the information.
Even if your parental rights were terminated you can adopt your son if you go through the proper procedures. I would need to talk with you about why those rights were suspended or terminated in the first place, then plan out a course of action. You really need to get in front of a judge immediately to get some emergency temporary orders in place so that your son does not have to go back now. You have nothing in place preventing that at this time.
First, I have not sued CPS. I have worked with them and against them in cases, but not sued directly like you are seeming to want.
You really need to sit down with an attorney, take all of the pleadings, a timeline, and a list of possible negligent/harmful actions they have done and discuss it with that attorney. Suing governmental entities tends to be very difficult, but not impossible. Good luck.
Any attorney licensed to practice law in Texas and that is competent to file/argue and appeal can help you. With this particular case, you may want to put up a bond or put those monies into the Court's registry to show your good faith and not incur additional penalties. Then, once the appeals process is done, the Court would release those funds to the party it belongs to. You have a limited time to appeal the decision, so you need to hire an attorney or begin the process immediately.
