Hi,
It is not clear whether you have a tie-up with LIC under the Group Gratuity Scheme. If you have a tie-up with LIC for gratuity, you can process gratuity for the deceased employee through LIC. If you don't have a tie-up with LIC, then your employer is bound to pay gratuity for 2 years since the nature of the exit is due to death. As per the provisions of the Gratuity Act, the deceased employee is eligible for gratuity, even though the number of years is less than 5 years.
