Confirmation of Non-existence of a Parent-Child Relationship | Successful Proof of Non-existence of a Parent-Child Relationship, Winning the Case
This is a case in which a client who sought to pursue the legal procedure for confirmation of the non-existence of a parent-child relationship, with the assistance of our firm's family law attorney, succeeded in correcting the family register.
1. A Client Who Needed Confirmation of the Non-existence of a Parent-Child Relationship
This is the account of a client who visited our firm to pursue a lawsuit seeking confirmation of the non-existence of a parent-child relationship.
Background of the Case as Identified by the Family Law Attorney
The client's paternal grandmother later learned that, during a past remarriage, the other party had used her personal seal without her knowledge to file a false birth registration.
As a result, persons who had no blood relationship with her whatsoever were recorded in the family relations register as the children of the client's paternal grandmother.
Because of this, decades later the client's paternal grandmother found herself in a situation in which she even received notice of an unjust debt on account of the false family relationship recorded under her name.
To correct the family relations register, which did not reflect the truth, she filed a lawsuit for Confirmation of Non-existence of a Parent-Child Relationship with the court.

2. Legal Response Strategy to Prove Non-existence of a Parent-Child Relationship
To assist the client, who filed a lawsuit for Confirmation of Non-existence of a Parent-Child Relationship, in correcting the information erroneously recorded in the family relations register, the family law attorney provided the following support.
In particular, the attorney focused on proving how the plaintiff came to be falsely registered as the defendants' biological mother and the inconsistencies in the facts.

Family Law Attorney's Support ① | Establishing and Proving the Circumstances of the False Registration
The client's paternal grandmother (the plaintiff) was aware that her spouse had children from a former marriage at the time of the remarriage decades ago, but she had no blood relationship with them whatsoever.
However, it later came to light that at the time of the remarriage, the spouse filed birth registrations for the children of the former marriage without the plaintiff's consent and falsely recorded the plaintiff as their biological mother.
This issue was discovered when the plaintiff happened to receive a notice of an inheritance-related claim issued in her name. Upon checking her family relation certificate, she learned that a false family relationship had been legally formed without her knowledge.
Key Points of the Attorney's Support
Accordingly, the family law attorney concentrated on proving the timing and circumstances of the false birth registration, as well as the fact that the plaintiff's intent and awareness were not involved at all.
In particular, by analyzing the marriage relation certificate and the birth registration documents from that time, the attorney set out in concrete terms the temporal and factual circumstances under which the plaintiff could not have been recorded as the biological mother.
In addition, where the elderly plaintiff's memory was unclear, the attorney supplemented it with written statements from family members and objective materials.
As a result, the attorney was able to explain persuasively to the court that the birth registration had been carried out by the unilateral act of the spouse, without the plaintiff's consent or involvement.
Family Law Attorney's Support ② | Applying for and Confirming the DNA Test Order
To objectively negate the falsely formed parent-child relationship, the family law attorney applied to the court for an order requiring a DNA test.
In a lawsuit for Confirmation of Non-existence of a Parent-Child Relationship, this is a key procedure for scientifically proving whether a blood relationship exists, and it was a measure taken to secure evidentiary weight beyond a mere assertion.
Summary of the DNA Test Results
: Between the plaintiff and the defendant, no genetic mother-child relationship exists
⇒ Combined with the facts of the false birth registration, the appraisal report served as decisive evidence
This appraisal result served as decisive evidence supporting that registering the plaintiff as the defendant's biological mother was a clear error, and it lent strong persuasive force to the court's determination.
Family Law Attorney's Support ③ | Proving the Interest in Confirmation
The family law attorney did not stop at establishing the non-existence of a blood relationship, but also actively argued that the plaintiff had a legal interest in confirmation in this lawsuit.
Key Points in Proving the Interest in Confirmation
∙ Mental distress caused by a legal status that differs from the facts
∙ The need to stabilize the legal status and resolve the uncertainty through the lawsuit
Through this reasoning, the attorney made clear that the plaintiff had filed this lawsuit for the substantive reason of resolving the uncertainty in her legal status.
3. Successful Confirmation of Non-existence of a Parent-Child Relationship

Following the systematic support provided by the family law attorney in the lawsuit for Confirmation of Non-existence of a Parent-Child Relationship, the court clearly recognized that no parent-child relationship existed between the plaintiff and the defendant.
Accordingly, the court granted the plaintiff's claim and rendered a judgment correcting the erroneously recorded portion of the family relations register, and the client was able to be freed from the false family relationship that had been formed without her knowledge for decades.
