La. Stat. tit. 9 § 3533
Except as provided in R.S. 9:3527, if the maturity of a consumer credit transaction is accelerated for any reason and suit is filed, the obligation shall be credited with the same rebate required under R.S. 9:3532(A) or (B), as applicable, as if prepayment in full had been made as of the date the maturity of the obligation is accelerated at the creditor's election, except that any credit life insurance and health and accident insurance in force at such time shall not be rebated until payment is made in full; thereafter the obligation sued upon shall be deemed to bear a loan finance charge or credit service charge on the amount due at the annualized rate previously agreed to by the consumer until the transaction is paid in full.
