Gratuity nominations require employees (after one year) to name beneficiaries, with family preference and amendment rules. Section 55 requires an employee with one year of service to make a gratuity nomination in the time, form and manner prescribed by the appropriate Government; nominations may allocate gratuity among multiple nominees. If the employee has a family at nomination, nominations must be made to one or more family members; nominations to non-family members in that case are void. Absent a family, nomination may be made to any person but may be replaced by a fresh nomination in favour of family members if a family is subsequently acquired. Nominations may be modified by written intimation to the employer, and a predeceasing nominee's interest reverts to the employee, who must make a fresh nomination; the employer must keep nominations in safe custody.
