请教出庭问题 probate court

I am the parent of child who is beneficiary of her father's trust and estate. I have an  estate court hearing filed by estate administrator and their attorney. It is final hearing to close the estate. According to the endorsed file, the attorney is going to charge the fee by percentage and administrator is going to charge fee too.

But there was a court order filed earlier when I tried to take out my property from estate. The ordered said the attorney can only charge by hours on the case and administrator waived the fee.

 I plan to show at hearing and tell judge about it. What should I do before hearing? Do I have to file document to court an let court know my position before hearing? I don't have attorney. I know there is some kind of format document to respond to court. Do I have to use that format or I can write anything in my format?

Or I can just present in court with previous order and tell judge about it.  I told administrator attorney shouldn't charge that much, they didn't listen to me and signed on the endorsed file.

Do I have to talk to their attorney and let him know he should only charge fee by hours before hearing? I am afraid he wouldn't listen to me.

I think both attorney and administrators are cheating and ignored the pervious order.

It is in CA. Urgent. Thanks!
