The mediator will go back and forth from your room to the other side’s room speaking to each side privately.
The mediator will talk to you about offers you might want to put forward to the other side and tell you about any offers they have made.
You can always ask the mediator to leave the room if you want to discuss an offer with just your supporter and lawyer.
The mediator may talk to you and your lawyer about what the other side say are the weakness of your case.
This process carries on until you and the other side reach an agreement. There may be many offers before a settlement is reached.
