after settlement's divorce cou

Asking help on after settlement's divorce (custody, property, all) court hearing.

We had two lawyers before.
We decided to settle and hired a new lawyer.
The old lawyer already be notified by the 3rd lawyer are severing for us.
The 3rd lawyer sent to the settlement documentation to the court.
The court said both of us need go to the court for ex-scheduled hearing and the old lawyer need not go there.

Question:
1) What the judge will let us to answer?
2) Anything we should pay attention?

Thank you very much!
