I'm really sorry to hear that this is happening to your family, and hope you have a good attorney.
I know these situations can seem hopeless, and frankly some are, but in many cases the legal proceedings play out simply because the other side doesn't know or do anything to contest them.
And searching out an advocate and having a phone call with them is a really low bar considering the ability for them to possibly change the trajectory of the situation.
Best of luck with this.
