According to the above facts, the Defendants, F’s heir, are obligated to pay to the Plaintiff money calculated by each of the 8,069,127 won (40,345,635 won x 1/5 of their respective shares in inheritance) and the 8,001,989 won (40,09,947 won x 1/5 of the same x 1/5) among the joint and several debt obligations of the Plaintiff inherited from the Plaintiff, which is 12% per annum from September 19, 2015 to March 16, 2016, and 15% per annum from the next day to the date of full payment.
