How to prove paternity if the father is deceased?

When the father has passed away, the parent-child relationship can be proven through paternity tests, birth medical certificates, household registration files, relatives' testimonies, and court judgments.

1. Paternity test

The genetic relationship is determined by comparing the DNA samples of the children and their father's direct relatives, such as grandparents, brothers and sisters. A report needs to be issued by a forensic appraisal agency and has legal effect. If the father retained biological samples such as blood stains and hair during his lifetime, direct comparison can also be made.

2. Birth medical certificate

If the birth certificate clearly records the father's information, it can be used as direct evidence. Those who have lost it can apply for a replacement from the original issuing institution, or retrieve the hospital delivery files. Birth certificates issued uniformly in China after 1996 must contain the identity information of both parents.

3. Household registration files

If the father-son relationship is recorded in the household registration system of the public security organ, you can apply to retrieve the permanent population registration form, historical household registration transfer records, etc. In rural areas, you can check the original household registration book kept by the village committee, and some files may contain documents proving the father-son relationship.

4. Testimony of relatives

Collect written testimonies from the father’s colleagues, relatives, friends, neighbors and other insiders during his lifetime, which must contain specific factual descriptions. The testimony of immediate family members such as grandparents and uncles is more effective and can form an evidence chain with other evidence.

5. Court decision

By filing a lawsuit to confirm parent-child relationship, the court will make a decision after comprehensively reviewing the evidence. Applicable to situations where direct evidence is lacking, auxiliary materials such as recordings and letters confirming the parent-child relationship must be submitted.

It is recommended that priority be given to confirming the relationship through objective evidence such as forensic appraisal or birth certificates. If the materials are missing, evidence can be supplemented through multiple channels. When handling legal matters such as inheritance, family relationships must be notarized in advance. Pay attention to retaining original evidence during the process, and consult professional lawyers to assist in material preparation when necessary. For foreign-related or complex situations, evidence formed abroad can be obtained through consular authentication, transnational judicial assistance and other channels.
