Also, according to present Korean law, the traditional adoption after death of a foster parent to continue the line has been outlawed by legislation as of 2004. While the line of Prince Gang is the senior line following the death of Prince Gu, there are descendants of the elder sons of Prince Gang.
In this case, the rightful Head of the House is Yi Chung, Prince Wu"s eldest son.
