Pennsylvania Statutes Title 40 P.S. Insurance § 511b. Payment of Benefits

(a) Except as set forth in subsection (b), life insurance death benefits not paid within thirty days after satisfactory proof of death was submitted to the insurer shall bear interest at the rate of interest payable on death benefits left on deposit by the beneficiary with the insurer. This interest shall accrue from the date of death of the insured to the date the benefits are paid to the beneficiary. In cases where satisfactory proof of death is submitted more than one hundred eighty days after the death of the insured and the death benefits are not paid within thirty days after satisfactory proof of death was submitted to the insurer, interest shall accrue from the date on which satisfactory proof was submitted to the date on which the benefits of the policy are paid.

(b) Notwithstanding section 6 of the act of May 11, 1949 (P.L. 1210, No. 367), referred to as the Group Life Insurance Policy Law  1, this section shall apply to all life insurance policies except variable insurance policies.

(c) The term “left on deposit” shall mean a specific settlement option provided within the life insurance policy under which the death benefit proceeds are retained by the insurer for the beneficiary and are credited with a specific rate of interest.
