Company not paying Employee Dues and Gratuity

I am doing the job in a Private Limited company from 8 years. Now I am leaving this company, I gave a notice period of 60 days to the company. But it was oral between Company director and me. There is no proof in writing. I heard from previous company employees that the company has not paid Share to previous 2 employees. One did 12 yrs and second employees spend 10 yrs in this company. So I have doubt that maybe the company will not pay my Share also. The company deducts 2.5% share from every month salary. and They promise that they will give a double amount when any employee leaves this company. They said that they will transfer my share after 3 months of leaving the job. But previous employees did not get their fund even after 7 months. There is also no Gratuity system. I spend 8 yrs in this company but I have not to get Gratuity. No medical insurance & Gratuity. I want to know what I can do if the company will not pay my Share amount after 3 months? I can go to Labour Court?
