Assistance of the Uijeongbu Law Office | Prevailing in a Suit for Non-Existence of a Parent-Child Relationship by Proving No Biological Parentage
The client sought a suit for confirmation of non-existence of a parent-child relationship. The Uijeongbu attorney assisted with the litigation and proved that no biological parent-child relationship existed.
1. How the Client Came to Visit the Uijeongbu Law Office

The client needed to set the family register in order through a suit for confirmation of non-existence of a parent-child relationship so that inheritance disputes would not arise among the children, and the client requested the assistance of the Uijeongbu attorney. The Uijeongbu attorney collaborated with attorneys nationwide to assist the client.
The Circumstances That Led to Visiting the Uijeongbu Law Office
The family register of the client lists both a biological child and a stepchild.
The client's former spouse had registered a child born with an affair partner on the client's family register.
The client was unaware of this fact, and the biological mother of that child had passed away.
As a result, the client's family register lists a child born with the former spouse, a child born with the current spouse from remarriage, and the child of the former spouse and the affair partner.
After the remarried spouse passed away, the client, concerned about inheritance issues following the client's own death, sought to set the family register in order and requested the assistance of the Uijeongbu law office in a suit for confirmation of non-existence of a parent-child relationship.
The Suit for Confirmation of Non-Existence of a Parent-Child Relationship as Explained by the Uijeongbu Law Office
The Uijeongbu law office explained the suit for confirmation of 🔗non-existence of a parent-child relationship.
Non-existence of a parent-child relationship refers to a procedure in which, where a child presumed to be biological is not in fact a biological child, a suit relating to non-existence of a parent-child relationship is filed to confirm that the child is not a biological child.
The suit for confirmation of non-existence of a parent-child relationship is a lawsuit filed to confirm that a biological parent-child relationship between a parent and child on the family relation register does not in fact exist.
It is primarily pursued in situations such as the following.
1. If a person who is not the biological parent is recorded as a parent on the family relation register
2. If a child born with a third party before divorce from a former husband is registered as the child of the current husband
3. If a child born at home rather than at a hospital is registered with parents arbitrarily recorded
■ Why a Suit for Confirmation of Non-Existence of a Parent-Child Relationship Is Needed
The reason a suit for confirmation of non-existence of a parent-child relationship is needed is to correct an erroneous family relationship.
If a person who is not a biological child is listed on the family relation register, property issues such as inheritance or gifts may arise, and it may be disadvantageous for benefits such as family allowances or survivor's pensions.
In addition, in the case of a child born out of wedlock who has a separate biological father, if the child is registered with the biological mother as the mother, it may later become difficult to have the biological father recognized as the father.
The Key Issues of the Suit as Explained by the Uijeongbu Law Office
The Uijeongbu law office explained the key issues of the client's suit for confirmation of non-existence of a parent-child relationship.
The client did not even know that a stepchild who was not a biological child was registered on the family relation register.
The Uijeongbu law office noted that it would be necessary to prove, through a DNA test of the client and the stepchild, that no biological parent-child relationship existed.
