1. The Client Who Came to Our Family Law Specialist Attorney

The client who came to our family law specialist attorney had been sued by her younger siblings in an action for confirmation of non-existence of a parent-child relationship, but with the assistance of the family law specialist attorney, this is a case in which she was able to defend against it and protect her right of inheritance.

Background of the Family Case

The client was the eldest daughter of five siblings and had grown up her entire life as her father's daughter.

However, when the father passed away, the younger siblings demanded that she renounce her inheritance, claiming that "our older sister is a child born out of wedlock whom our mother bore before marrying our father, so she is not a biological child and has no right of inheritance."

Furthermore, one of the younger siblings even filed an action against the client for confirmation of non-existence of a parent-child relationship.

In response, the client, emphasizing the fact that her father had personally registered her birth and had raised her as his own daughter, requested help from our family law specialist attorney in order to protect her right of inheritance.

2. The Laws Relevant to the Case as Explained by the Family Law Specialist Attorney

The family law specialist attorney first explained in detail the action that had been brought against the client.

An action for confirmation of non-existence of a parent-child relationship is a legal procedure conducted to obtain a finding that a parent-child relationship does not exist, on the ground that there is no blood relationship.

If, through this procedure, the absence of a parent-child relationship is confirmed, the legally registered family relationship may be deleted or corrected through a correction of the registry, which has a significant effect on matters such as kinship relations and inheritance.

The Key Issues in This Family Case

The key issue in this family case was whether, even in the absence of a blood relationship, a legal adoptive parent-child relationship can be deemed to have been established where the father registered the birth as that of a biological child with the intent to adopt.


The younger siblings were claiming that there was no parent-child relationship, on the grounds that the client was a child born out of wedlock and on the basis of a genetic test result.


In response, the family law specialist attorney established a case strategy that emphasized the point that the father's birth registration has the effect of an adoption report and that focused on proving that the client had lived with her father from her minority and had, in substance, been raised as his biological daughter.

① Whether a birth registration as a biological child made with the intent to adopt, even in the absence of a blood relationship, establishes a legal adoptive parent-child relationship

② The legal priority between the genetic test result and the actual rearing relationship and the effect of the birth registration

③ Whether the substantive fact of rearing and the family relationship can be recognized as having the effect of an adoption report

3. The Assistance Provided by the Family Law Specialist Attorney

Family law specialist attorney assistance provided legal consultation

The family law specialist attorney provided assistance as follows, ensuring that the plaintiff's claim that no parent-child relationship existed between the client and her deceased father could be dismissed.

Organization of the Facts and the Evidentiary Materials

The family law specialist attorney organized, on a year-by-year basis, specific facts such as the circumstances of the client's birth registration, the consistency of the address on the resident registration during her minority, and the father's role at her wedding.

Through this, it was clearly established that, in substance, the father had raised the client with the intent to adopt.

Review of Supreme Court Precedents and Legal Principles

The family law specialist attorney closely reviewed Supreme Court precedents concerning the effect of a 'birth registration made with the intent to adopt' and the 'permissible scope of a claim for confirmation of non-existence of a parent-child relationship'.

On this basis, the attorney presented cases in which the court had recognized the effect of an adoption report, and constructed a legal counterargument against the plaintiff's claim.

Supreme Court Judgment of February 23, 1988, Case No. 85Meu86

Where a party, with the intent to create an adoptive parent-child relationship, registers a birth as that of a biological child, and all of the substantive requirements for adoption are met, then even if there are some defects in its form, … the false biological-child birth registration in this case functions as an adoption report that publicizes the adoptive parent-child relationship, which is a legal parent-child relationship.

In such a case, … unless there are special circumstances, such as a need to dissolve that adoptive parent-child relationship, a claim for confirmation of non-existence of a parent-child relationship, which would cancel the family register entry itself and thereby deny the existence of the legal parent-child relationship, cannot be permitted.

Pointing Out and Rebutting the Contradictions in the Plaintiff's Claim

The plaintiff claimed that the client had run away from home around the time of her high school graduation and had, in substance, lived on her own.

In response, the family law specialist attorney presented the following points as evidence, highlighting that the plaintiff's claim was inconsistent and did not accord with the facts.

4. The Result of the Family Law Specialist Attorney's Assistance: Rejection of the Plaintiff's Claim

As a result of the assistance provided by the family law specialist attorney, the court recognized the legal adoptive parent-child relationship between the father and the client and did not accept the claim for confirmation of non-existence of a parent-child relationship brought by the younger siblings.

Accordingly, the client was able to protect her right of inheritance and her legal status.
