Singer and DJ Koo Jun-yup has revealed that he registered his marriage with the late Seo Hee-won in Taiwan, raising the possibility of a legal battle over an inheritance worth 120 billion won and the custody of their two children.
In 2022, Koo Jun-yup appeared on tvN's "You Quiz on the Block" and shared his love story with Seo Hee-won, stating, "This photo was taken on the day we registered our marriage. In Taiwan." This has increased the likelihood that the controversy surrounding the alleged lack of marriage registration in the local area is not true.
However, even if Koo Jun-yup registered the marriage, the existence of Seo Hee-won's will is expected to be a significant variable in the distribution of the inheritance. According to Taiwanese lawyers,

What if a will exists? → Inheritance distribution according to the will
What if there is no will? → According to Taiwanese law, Koo Jun-yup and the two children would inherit 1/3 each
If the marriage registration is recognized? → Koo Jun-yup could inherit as a legal spouse
The issue is that the custody of the two children born to Seo Hee-won and her ex-husband Wang Xiao-pei would automatically transfer to the biological father. Under Taiwanese law, if one parent dies after a divorce, the surviving parent retains custody, which increases the likelihood that Wang Xiao-pei will manage the inheritance for the children.

Koo Jun-yup vs. Wang Xiao-pei, is a legal confrontation inevitable?
There are analyses suggesting that Wang Xiao-pei, who previously sued Seo Hee-won over property issues, is likely to take legal action again this time.
In the past, Wang Xiao-pei stopped paying alimony after the divorce
Seo Hee-won applied for enforcement in court → Wang Xiao-pei's assets were seized
There is a possibility of aiming for custody and managing the inheritance
Taiwanese media reported that even though Koo Jun-yup registered the marriage, it remains uncertain whether he can protect Seo Hee-won's inheritance and the children without resolving the legal issues.

Will Koo Jun-yup survive the legal battle and be able to protect the last inheritance and family of his beloved Seo Hee-won until the end? The future is worth watching.
