Procedure for waiving the court fees in a labour case

The Tawafouq centre transferred my case to the court and they gave me papers to submit in Al Adhid centre. When I went there for the submission of my paper, they took all the papers and made a file for my case.

They asked me to pay the court fee of AED 6635 to register my case in the court, but I don't have money because my company did not give me a salary for the last 4 months.

I want to know if I can pay the court fee after the judgment or its necessary to pay the court fee first then your case will be registered.

Please explain; my total amount is 131665.
