Gratuity nomination procedure requires Form-III filing, employer verification, and timely fresh nomination or modification on family changes. Nomination for gratuity under Form-III must be submitted in duplicate to the employer by personal delivery, registered speed post, or electronically, within the prescribed time. The employer must verify service particulars, attest and return one copy, and retain the other. A fresh nomination is required after acquiring a family, and modification may be made where a nominee predeceases the employee. The nomination takes effect on receipt by the employer.
