South KoreaDoes an adopted child have inheritance rights?
Yes, an adopted child has the same inheritance rights as a biological child under South Korean law.
What the Law Says
South Korean law treats adopted children identically to biological children for inheritance purposes.
Under the South Korean Civil Act, adoption creates a full legal parent-child relationship. This means all rights and duties between parents and children — including inheritance — apply equally.
The law makes no distinction between biological and adopted children when determining heirs or distributing estates.
An adopted child is considered a 'direct descendant' and qualifies as a statutory heir in the first order of succession, alongside biological children.
Statutory TextAn adopted child shall have the same rights and duties as a biological child with respect to the adoptive parents and their relatives.
— Civil Act, Art. 1002 — Effect of Adoption
What to Do
Ensure the adoption is legally finalized through family court approval under the Civil Act.
Confirm that the adoptive parent’s will (if any) does not expressly disinherit the adopted child — though even then, reserved portion rules may apply.
File for inheritance registration at the local Legal Affairs Bureau within 6 months of the adoptive parent’s death if claiming statutory inheritance.
Consult a Korean-licensed attorney to verify heir status and manage estate division, especially if other heirs dispute the adoption’s validity.
