Unlike situations in some states in the U.S., a prenuptial agreement is somewhat in a grey area in the Korean legal system.

When the case later goes into a divorce by agreement, the prenup will be fully honored by the court.  It is legal and enforceable in Korea.

When the case, however, goes to a judicial divorce or a contested divorce, the Korean court applies a more strict standard in honoring the validity and application scope of the prenuptial agreement, which in many cases results in nullifying the prenuptial agreement.
