At a young age, he was given up for adoption by his biological mother to the Kim family, and his name was changed to Kim Jae-joong. On November 21, 2006, a man with the surname Han filed a lawsuit against Kim's guardians. Han claimed he was Kim's biological father, and thus wanted parental rights.
Han cited the reason for the lawsuit against Kim's legal guardians as "for not going through the proper procedures before registering [Jaejoong] in [the legal guardians'] custody." The first hearing was to be held in Kim's hometown, Gongju, on November 29, 2006, but on November 22 Han dropped the charges against Kim's legal guardians.
In reaction to the matter, Kim uploaded a journal entry on his official fan club website, and said that he was informed of the existence of separate biological parents by his mother two or three years ago, and it had been quite a shock to him.
With his adoptive mother's support, his biological mother was able to keep in touch with him, and to meet occasionally, but whereabouts of his father had been unknown. He expressed his will to live by the name of Kim Jae-joong, not by his birth name Han Jae-jun.
