I think that the question relates to the claim process in the event of permanent disablement or death of an employee covered by an insurance policy specifically taken under the EC Act,1923 due to an employment accident.
In such a situation, first the employer has to officially inform the insurer about the accident.
After the treatment is over, the employee has to submit his claim for compensation to his employer with a disability certificate issued by a registered medical practitioner. In the case of death, the dependents have to file the claim with death certificate.
In actual practice, Insurance Companies do not come forward to settle such claims directly. Therefore, the employee/ his dependents are required to file a claim before the area Commissioner for Employees Compensation against the employer and the Insurance Company together with copies of proof of employment, FIR if any, hospital documents relating to the treatment taken with bills, if the treatment expenses are incurred by the employee, disability or death certificate, legal heir certificate etc. The Commissioner would conduct a quasi Judicial enquiry and dispose of the claim accordingly.
As the procedure involves some minimum legal formalities, it is better to engage the services of a advocate from the very beginning.
