Gratuity fund nomination rules govern valid nominees, family-based nominations, modifications, and minor nominee guardianship. Nomination under the gratuity fund rules allows an employee, with trustee approval, to nominate one or more persons in the prescribed form to receive gratuity on death before payment or if unpaid after becoming payable. Multiple nominees must have their respective shares or amounts specified. Where the employee has a family, nominations must be in favour of family members only; a non-family nomination is invalid. A later-acquired family invalidates an earlier non-family nomination, and the employee may make a fresh family nomination.
