Dear Sushil, you have strong proof that your deceased member was under the medical care of ESI, thus was in your employment. I hope you have not mentioned the date of leaving as 30.11.2016 in ECR.
Submission of Forms
Submit PF Form 20, 5 IF (DLIS), and Form 10 C (in the case of a deceased member who died after attaining 58 years of age but before the completion of 10 years of eligible service, withdrawal benefit to family/nominee/legal heir) along with the original death certificate and passport size photographs duly attested by the employer.
Communication with PF Authority
You can write to the PF Authority stating that the deceased member was on authorized sick leave, duly certified by the ESI Medical Practitioner, thus was in continued employment and eligible for insurance fund under DLIS.
Additional Documentation
Include a succession certificate in the case of an application by the legal heir after the death of the member. Also, provide a copy of a blank/cancelled cheque/passbook, and copies of the Aadhaar Card and PAN Card.
Regards, Suresh
