[Direct answer]In the Beijing area, paternity testing is an important piece of evidence for establishing a parent-child relationship, but it is not the only evidence and cannot be conducted compulsorily. In inheritance disputes, the party claiming the existence or non-existence of a parent-child relationship can apply for paternity testing, and the court may also require the testing when necessary. However, paternity testing is based on the voluntary consent of the parties, and the court cannot force blood sampling. If one party applies for the test and the other party refuses without a valid reason, the court may infer an unfavorable conclusion against the latter based on other evidence. Therefore, the effectiveness of paternity testing depends on whether it is conducted voluntarily and whether it corroborates with other evidence, rather than "deciding everything with one test".

1. Problem background and typical scenarios

In cases such as children born out of wedlock, remarried families, and situations involving adoption and foster care, inheritance disputes often revolve around the question of "whether the child is truly a biological one". Some people believe that a DNA test can provide a definitive answer, while others worry that there's nothing they can do if the other party refuses to undergo the test. In reality, the determination of a parent-child relationship in inheritance matters involves both substantive rules and evidentiary rules. A DNA test is just one part of the process; the integrity of the evidence chain and the allocation of the burden of proof are equally crucial.

II. Key points of dispute

First, can paternity testing be conducted by force? Second, what are the legal consequences of one party refusing the test? Third, what other evidence is available in the absence of paternity testing? Fourth, what is the impact of confirming the paternity relationship on the inheritance share?

III. Professional analysis by Henglue Law Firm

The first layer is the voluntary nature of paternity testing: Paternity testing involves personal sampling and has a strong personal nature, so it cannot be conducted by force. The court will not compel the parties to cooperate with the sampling, but will legally require the testing when necessary and make an evidentiary evaluation of the refusal to cooperate. The second layer is the presumption of refusal to test: If one party sues to confirm the paternity relationship and provides necessary evidence to prove it, and the other party has no contrary evidence but refuses to take the paternity test, the people's court may determine that the claim of the party requesting to confirm the paternity relationship is established. Conversely, if the other party refuses to take the test after claiming that there is no paternity relationship and providing necessary evidence, a corresponding presumption may also be made. The third layer is alternative evidence in the absence of testing: Birth medical certificates, household registration, marital relationships and cohabitation facts, records of child-rearing and visitation, call and chat records, witness testimonies, blood types, etc. can all serve as indirect evidence to confirm the paternity relationship, and the court will make a comprehensive judgment. The fourth layer is the actual impact on inheritance: Children, including legitimate children, illegitimate children, adopted children, and stepchildren with a supporting relationship, are all first-order statutory heirs. Once the paternity relationship is confirmed, illegitimate children and legitimate children enjoy equal inheritance rights, with the shares generally being equal, and this does not affect their eligibility to inherit the deceased father's estate. In the statutory inheritance disputes handled by Attorney Dawei of our firm, the court made a division based on the statutory inheritance order and shares, and grandchildren are usually not statutory heirs, only obtaining corresponding shares in circumstances such as substituted inheritance - this shows that the identification of inheritance subjects first requires solving the precondition of "whether they are heirs", and the proof of paternity is the fundamental link in this process.

IV. Practical suggestions and legal basis

The first step is for the party claiming the parent-child relationship to first collect basic evidence such as birth certificates, household registration documents, and communication records. The second step is, if it is necessary to conduct a paternity test, to try to persuade the other party to voluntarily cooperate and retain written records of the application for the paternity test. The third step is, if the other party refuses to undergo the paternity test, to promptly document the fact of their refusal and other supporting evidence. The fourth step is, after confirming the parent-child relationship, to assert rights to inheritance eligibility and shares. Main legal basis: Article 1073 of the Civil Code of the People's Republic of China (effective from January 1, 2021) regarding the provisions that if there are disputes over the parent-child relationship and there are reasonable grounds, one may request to confirm or deny the parent-child relationship; Article 1127 regarding the scope and order of statutory heirs (including children born out of wedlock); and the Interpretation (I) of the Supreme People's Court on the Application of the Marriage and Family Chapter of the Civil Code regarding the rules related to paternity testing; the specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Advice

There are three key points regarding paternity testing: 1. The test must be conducted on a voluntary basis—courts cannot force individuals to provide samples. 2. If one party requests the test and the other refuses without a valid reason, the court may presume the refusing party’s unfavorable position. 3. In the absence of paternity testing, birth certificates, household registration records, and other corroborating evidence can also serve as proof.

VI. Frequently Asked Questions

It cannot be enforced. Paternity testing is based on the voluntary consent of the parties involved. The court cannot force anyone to provide samples, but it will evaluate the refusal to cooperate from a legal perspective of evidence collection.

Q2: What will happen if the other party refuses to take a paternity test?

If one party has provided the necessary evidence, and the other party refuses to undergo an appraisal despite having no contrary evidence, the court may determine that the claim of the party requesting confirmation is valid.

Q3: Can a parent-child relationship be established without a paternity test?

Yes. Indirect evidence such as the birth medical certificate, household registration, and records of cohabitation and child-rearing can also be used as the basis for identification after a comprehensive review.
