Though you have not provided sufficient information like the cause of death or duration of employment, the best answer would be based on the assumption that your company is meeting all compliance requirements. The nominees of the deceased employee are entitled to a pension from the provident fund department, including the children below 18 years until they meet this age criterion. Claiming the provident fund by the nominee can be done, and funeral expenses of the deceased employee can be covered by ESI.
If the death occurred at work, then the company has to pay compensation as per the Workmen's Compensation Act 1923. The amount of compensation to be paid depends on the nature of the injury, the average monthly wages, and the age of the workmen. This amount would be decided by the assistant labor commissioner of your area. I hope you have taken a Workers' Compensation policy and informed the labor department about the death.
