1. The Client Who Sought Us Out to File Litigation to Confirm the Non-Existence of a Parent-Child Relationship

This is a case in which the client who brought a confirmation of non-existence of a parent-child relationship lawsuit, through the assistance of a family law specialist attorney, proceeded with the confirmation of non-existence of a parent-child relationship lawsuit, obtained the desired result, and was able to proceed smoothly with the inheritance procedures.
The Circumstances of the Case as Identified by the Family Law Attorney
In the past, the client's father had, at the request of his remarried spouse, temporarily registered in the family register a child that the woman had brought with her.
It was a temporary measure for the child's school enrollment, and several decades passed thereafter without any contact with the child.
Recently, while preparing the inheritance procedures after his father's death, the client discovered that a person he did not remember was registered as a child in the family relations register.
This created the possibility of an unexpected inheritance dispute, and the client therefore sought out a family law attorney in order to pursue a lawsuit for confirmation of non-existence of a parent-child relationship.
2. How to File Litigation to Confirm the Non-Existence of a Parent-Child Relationship
A lawsuit for confirmation of non-existence of a parent-child relationship is a procedure for legally establishing that no actual blood relationship exists between a person registered as a legal child and another.
Under Article 865 of the Civil Act, if it can be proven that no actual parent-child relationship exists, confirmation may be sought from the court.
In sensitive situations such as inheritance in particular, a prompt response is necessary.
① A person who may file a lawsuit under the provisions of Articles 845, 846, 848, 850, 851, 862, and 863 may file a lawsuit for confirmation of the existence or non-existence of a parent-child relationship on other grounds.
How to Secure Evidence to Confirm the Non-Existence of a Parent-Child Relationship
A lawsuit for confirmation of non-existence of a parent-child relationship proceeds by conciliation or adjudication of the family court, and in this case the burden of proof lies with the plaintiff who filed the suit.
Accordingly, it is very important to prove, through objective evidence, that there is no blood relationship.
The key evidence that may be used in the lawsuit is as follows.
∙ Circumstantial materials at the time of birth
∙ Obstetrics and gynecology and hospital medical records
∙ Witness statements and other materials such as texts and messages
3. The Family Law Attorney's Strategy for Litigation to Confirm the Non-Existence of a Parent-Child Relationship

Before bringing a lawsuit for confirmation of non-existence of a parent-child relationship, the family law attorney organized the issues of the case as follows.
- Determination of the proper respondent and the filing period for a lawsuit for confirmation of non-existence of a parent-child relationship brought after the death of the deceased
On the basis of these issues, the family law attorney prepared the lawsuit centering on a strategy of clarifying the facts and proving the matter through genetic testing.
Family Law Attorney's Assistance (1) | Comprehensive Review of the Family Relations Register and Removed Family Register
The family law attorney closely analyzed official documents such as the family relations register and the removed family register in order to ascertain how the defendant had come to be registered as a child of the deceased.
He concentrated on demonstrating that the registration in the family register had not been a voluntary adoption or a proper birth report, but a formal report made simply for convenience.
Family Law Attorney's Assistance (2) | Application for a Commissioned Genetic Examination
To objectively prove that the parent-child relationship did not actually exist, a genetic test was requested through the court.
The result of the DNA comparison of the defendant confirmed that there was no biological parent-child relationship, and this served as the key evidence in the litigation.
Family Law Attorney's Assistance (3) | Proving the Severance of the Factual Living Relationship
The attorney emphasized that there had been no contact or interaction whatsoever between that defendant and the deceased for decades.
Proving that there were no materials supporting the maintenance of any relationship, such as telephone calls, visit records, or messages, the attorney persuasively presented to the court that no substantive family relationship had existed.

Based on the arguments and proof of the family law attorney who handled the lawsuit for confirmation of non-existence of a parent-child relationship, the court legally confirmed that no parent-child relationship existed between the deceased and the defendant.
Accordingly, the plaintiff’s claim was granted in full, and the legal uncertainty in the inheritance relationship was also able to be resolved.
