Yes, you can change the nominee in your life insurance policy whenever you want to. To change the nominee, you would have to fill and sign a Nomination Form available with the insurance company. The form should then be submitted at any of the nearest branch of the company along with the KYC documents of the nominee. The documents should be self-attested by the nominee. Once the nomination form and documents are submitted, the insurance company would process the change of nomination within the next two working days.
