You can hire a lawyer and have them file a motion on your behalf seeking sanctions for the opposition filing frivilous motions seeking only to harass and annoy you. The lawyer can ask for costs and attorney fees and that the court sanction your ex and his lawyer if the filings are truly frivilous? The court is not going to award you $50,000.00 for a trial yet to take place in my opinion?
If the other lawyer's motions or conduct is unethical, you can also consider reporting them to the State Bar Ethics or Disiplinary Department.

You can certainly defend any motion brought and ask for sanctions based on the harassing nature of the claim. You will not likely get trial estimate and lawyer fees but you can get recompensed for the specific harassment.
You can file a motion seeking the other side to pay you money so you can hire an atty. Id suggest you talk to a few local attys that you might want to hire, and perhpas they will help you draft the motion.
