A case to claim my dues from employer for not paying my salaries for eight months

My salaries are not paid for 8 & 1/2 months, and for the past 6 months, my company kept me on unpaid leave. I have resigned with one month's notice.

My total dues shall be over 300K. The company says they can pay a maximum of 8 salaries in 8 months. I am planning to file a labor complaint at the end of the notice period.

Please advise how I can get my dues and what is the court procedures, I don't have any amount to survive with my family here. We all are suffering badly from huge debts.
