If the application is for payment of an invalidity benefit, the time limit is three months.
(2) If the insurer acknowledges the claim, or the policyholder and the insurer have agreed the reason for and the amount of the claim, the payment is due within two weeks. If the liability has been established on the merits only, the insurer pays an appropriate advance on the policyholder’s request.
