If the parents are married
Married parents exercise parental authority jointly.
If the parents are not married
The mother has it. The father can share it after he acknowledges the child, by agreement of the parents or a court decision.
The unmarried father, in one line: The mother has it; the father needs a step: a joint declaration, registration, agreement, or living with the mother at the birth.
After a divorce or separation
Divorcing parents must agree on who will raise the child, on contact and on child support, before the divorce is accepted. If they cannot agree, the family court decides in the child's best interests and can set the parenting arrangement.
What the child can say
The court takes the child's views into account according to age and maturity.
Moving house or moving abroad with the child
Where parents share parental authority, a move abroad needs both parents' consent or a court's permission.
If the parents live in different countries
South Korea is a party to the 1980 Hague Child Abduction Convention, which lets a parent ask for a child wrongly taken to another country to be returned. It works only with countries that have accepted its accession, so check the other country on the treaty status table.
Understand the legal system first
South Korea belongs to the Civil law family. Family law grows out of the legal tradition, so it helps to know how the system works.
