How to prove parent-child relationship when the father has passed away, proof template

When the father has passed away, the parent-child relationship can be proven through materials such as birth medical certificates, paternity test reports, household registration files, court judgments, and evidence of living together during his lifetime. It is necessary to choose a legally valid certification method based on the actual situation. If necessary, you can apply to the notary office for notarization of kinship.

1. Birth medical certificate

The medical birth certificate is the most direct document proving the parent-child relationship and is issued by a medical institution when a newborn is born. If the father's information column is completely registered and there is no dispute, it can be directly used as valid evidence. If the original certificate is lost, you can apply for a replacement or retrieve the stub file from the original issuing agency. When re-applying, parents’ identity documents and application instructions are required. Some areas require a loss statement.

2. Paternity test report

A scientific basis can be formed through DNA comparison, which must be issued by a forensic identification agency. After the father's death, biological samples such as hair, toothbrushes, etc. can be collected from his lifetime, or indirectly proved through the intergenerational kinship test of grandparents. The entire forensic identification process must be videotaped and the certificate chain retained. The report must include the identification institution’s qualification seal and the forensic signature. The uncontroversial appraisal results can be directly used in legal matters such as inheritance and settlement.

3. Household registration files

Household registration information has legal effect. You can apply to retrieve historical household registration files at the police station in the father's original place of residence. The applicant’s ID card and kinship statement are required. If the father-son relationship is clearly recorded in the file, the public security agency can issue a kinship certificate. If there are multiple migrations, the original registration records need to be traced step by step, and used with other supporting materials when necessary.

4. Court judgment

If the parent-child relationship has been confirmed in civil judgments such as custody rights and inheritance rights that have taken effect, it can be directly used as proof. It is necessary to obtain the original judgment or a copy of the court file to be used with the validity certificate. For children born out of wedlock, a judgment can be obtained through a lawsuit to confirm the parent-child relationship, but evidence such as letters, remittance records, etc. that the father recognized the custody during his lifetime must be provided.

5. Evidence of living together before death

Including family photos, correspondence, medical accompaniment records, school parent signature files and other traces of life. Such evidence must form a complete chain of evidence and be used in conjunction with witness testimony. For example, third-party archived materials such as family member registration in the father's unit's personnel files, insurance beneficiary records, and marriage and childbirth registration from the civil affairs department are more probative.

When applying for kinship notarization, it is recommended to collect all kinds of original materials in advance and go to the notary office to fill out the kinship notarization application form. The notary will verify the authenticity of the materials and may conduct on-site investigations. If estate disposal is involved, it is recommended to prepare death certificates, estate certificates and other documents at the same time. Daily care should be taken to properly keep the originals of important documents such as household registers and birth certificates, and scan and back up electronic files regularly. If there is a need for cross-border notarization, document authentication requirements must be confirmed in advance and, if necessary, go through the consular authentication procedures of the Ministry of Foreign Affairs.
