Utah Code § 31A-22-608
"REINSTATEMENT: If any renewal premium is not paid within the time granted the insured for payment, a subsequent acceptance of premium by the insurer or by any agent duly authorized by the insurer to accept the premium, without also requiring an application for reinstatement, shall reinstate the policy. However, if the insurer or agent requires an application for reinstatement and issues a conditional receipt for the premium tendered, the policy shall be reinstated upon approval of this application from the insurer or, lacking this approval, upon the 45th day following the date of the conditional receipt, unless the insurer has previously notified the insured in writing of its disapproval of the application. The reinstated policy shall cover only loss resulting from such accidental injury as may be sustained after the date of reinstatement and loss due to such sickness as may begin more than 10 days after that date. In all other respects the insured and insurer have the same rights under the reinstated policy as they had under the policy immediately before the due date of the defaulted premium, subject to any provisions endorsed on or attached to this policy in connection with the reinstatement. Any premium accepted in connection with a reinstatement shall be applied to a period for which premium has not been previously paid, but not to any period more than 60 days prior to the date of reinstatement."
