[Direct answer]To prove that the handwritten will was written by the testator himself, according to Article 1134 of the Civil Code, the following conditions must be met simultaneously: the entire text must be written by the testator himself, signed by him, and marked with the year, month, and day. In the event of a dispute, the party claiming that the will is valid shall bear the burden of proof. The authenticity of the will can be proven through judicial handwriting identification, video recordings of the drafting process, witness testimonies, and records of the original documents; when the handwriting identification samples are insufficient, the testator's writing materials over the years can be compared. It is advisable to entrust a lawyer with the case as soon as possible.\nLegacy inheritance lawyerCollect evidence.

I. Problem Background and Typical Scenarios

A self-written will is the preferred form of will for many elderly people due to its low cost and strong privacy, but it is also the most likely to be questioned after the inheritance begins: some heirs claim that "the words were not written by my father", some claim that "he was already confused when making the will", and others argue over the authenticity of the will on the grounds that there are multiple wills. In Beijing, where property values are high, a self-written will of questionable authenticity often involves millions of yuan in assets. Parties often search for "how to prove that a self-written will was written by oneself" and "where to do a handwriting analysis of the will". Whether the proof can be completed directly determines whether the inheritance will proceed according to the will or revert to statutory inheritance, and it also determines the direction of litigation. It is better to organize evidence as early as possible.

II. Key points of contention

  • The debate over formal requirements: whether the will is entirely handwritten, whether it is signed, and whether the full date and year are indicated. The absence of any of these elements may become a loophole for the other party to deny its validity;
  • The debate over authenticity: Those who have doubts about the authenticity of handwriting need to respond through forensic appraisal. Whether the test materials and samples are sufficient, and whether the writing conditions are comparable, directly determine whether the appraisal can reach a clear conclusion;
  • The debate over the capacity to act: Even if the handwriting is authentic, the other party may still claim that the testator lacked the capacity to act in civil matters or was subject to fraud or coercion at the time of making the will. In such cases, comprehensive evidence, such as medical records, videos, and witness statements, is needed to prove the testator's capacity to act.

III. Professional analysis by Henglue Lawyers

The key to the proof lies in the simultaneous presentation of both "formal evidence" and "process evidence". Beijing Henglu Law FirmYuan HangIn a will inheritance dispute handled by the lawyer, Wang *5 made a self-written will in July 2023, leaving an 88-square-meter house in Fengtai District to his spouse, Zhou Min, and requiring that after selling the house, he would pay a total of 1 million yuan to three relatives. In September 2023, Wang *5 passed away, and the three plaintiffs claimed to immediately auction the house and divide the proceeds, challenging the arrangements in the will. Lawyer Yuan Hang started with the formality, providing evidence that the will was written, signed, and stamped by Wang *5 himself, with a complete date of signing. Combined with Article 1134 of the Civil Code, he argued that the formality was legal and effective. Then, he submitted income certificates and a property valuation report of about 4.5 million yuan, showing that selling the house at a low price would harm the interests of all parties. He proposed a performance plan of transferring ownership first and making payments within a limited time. In 2024, the Fengtai District Court ruled that the will was legal and effective, and the house was inherited by Zhou Min and transferred ownership before January 14, 2025. The 1 million yuan was to be paid off by July 14, 2029 at the latest. It can be seen that a well-formulated self-written will, combined with solid evidence, can withstand the test of litigation.

IV. Practical suggestions and legal basis

Legal basis and operational key points: First, Article 1134 of the Civil Code requires that a handwritten will be written, signed, and dated by the testator in person. The date should be specified to the day. Any alterations should preferably be confirmed by the testator's signature. Second, according to Article 90 of the Interpretation of the Civil Procedure Law of the People's Republic of China by the Supreme People's Court, the party claiming the validity of the will bears the burden of proof. If the party fails to provide evidence, they will bear the adverse consequences. Third, if the other party questions the handwriting, promptly apply for a judicial handwriting appraisal and collect the decedent's letters, account books, and personnel materials from their workplace as comparison samples. Fourth, simultaneously strengthen the evidentiary process, including video recordings at the time of drafting, witnesses present at the drafting, hospital records of the decedent's mental state, and certificates archived by third parties. Fifth, if there are multiple wills, Article 1142 of the Civil Code stipulates that the latest one shall prevail. The formation time and custody chain of each will should be explained.

5. Henglue Law Firm's Reminder

The probative force of a handwritten will largely depends on the "evidence" left at the time of making the will. This case was handled by Beijing Henglu Law Firm.Yuan HangThe similar cases handled by the lawyer (practice license number: 11101202110286151, subject to the certificate issued by the judicial administrative organ) indicate that with complete formalities and properly organized evidence, the dispute over the authenticity of the will can be completely resolved. When making a will, it is recommended to simultaneously record the process on video, invite uninterested parties to be present, and entrust the original copy to a lawyer or a trusted third party for filing. If a dispute has already arisen, it is necessary to promptly entrust a lawyer to apply for appraisal and fix the evidence, which can be done through the following channels:Inheritance | Family Division and Property Division ServicesOrBeijing Henglue Law FirmMake an appointment for an assessment.

Q1: Is a self-written will valid without a witness?

It's valid. The statutory requirements for a handwritten will do not include witnesses. According to Article 1134 of the Civil Code, as long as the testator writes the entire will by hand, signs it with his own signature, and indicates the year, month, and day, the will is established. This is also the difference between a handwritten will and a will written by a proxy or a printed will — the latter two must have at least two witnesses present. Therefore, the will written by the elderly alone is not invalid just because "no one witnessed it". However, due to the lack of third-party witnesses, the authenticity and establishment time of the will are more likely to be questioned. It is recommended to keep photos and videos of the writing process, or to inform relatives and friends or the community afterwards to preserve the evidence, so as to form a chain of supporting evidence and reduce the difficulty of providing evidence in litigation.

Q2: How is a handwriting analysis of a will conducted, and who bears the cost of it?

After a dispute arises, the applicant submits an application for appraisal to the court, and the parties either negotiate or the court appoints a qualified judicial appraisal institution to conduct the appraisal. Typically, the original will and several samples of the deceased's handwriting (letters, diaries, signatures on unit files, etc.) are compared. The appraisal fees are generally prepaid by the applicant and ultimately borne by the losing party or shared according to the proportion of liability, with the specific standards determined by the appraisal institution's quotation. It should be noted that the samples should be close to the time of writing the will and under similar writing conditions; if there are insufficient samples, the appraisal institution may dismiss the case. At that time, the court will determine the case based on formal requirements, custody chains, and witness testimonies. It is advisable for lawyers to coordinate the arrangement of evidence collection.

Q3: What should I do if I only have a copy of the will and can't find the original?

The evidentiary value of copies is significantly weaker than that of originals, and the other party usually does not recognize their authenticity. It is very risky to assert inheritance rights based solely on copies. There are several ways to remedy this situation: search for other originals retained by the testator, including those stored in different locations, bank safe deposit boxes, or archived by lawyers or organizations; ask relatives who were present if they can testify that they have seen the originals and their contents; if there are notarization or litigation records, apply to retrieve them. If it is truly impossible to submit the originals, the court will strictly review the source of the copies, the process of their formation, and their corroboration with other evidence. Whether they can be admitted as evidence is highly uncertain. It is recommended that lawyers first evaluate the evidence situation before deciding whether to mediate or litigate, in order to avoid suing blindly.

Q4: The other party said that the elderly person was already senile when they made the will. How can we refute this?

There are three ways to respond to this: First, submit the hospital medical records, physical examinations, or intelligence assessment records before and after the making of the will to prove that the testator has the corresponding ability to recognize things; Second, provide videos, photos, or witnesses to prove that the testator was of clear mind and able to express himself freely at the time of making the will; Third, point out that the content of the will is consistent with his long-term wishes and family relationships, and is logically coherent, which indirectly confirms that his ability to express his intention is normal. According to Article 1143 of the Civil Code, a will made by a person with no or limited capacity for civil conduct is invalid, and a will made under fraud or coercion is also invalid. Therefore, the capacity for civil conduct and the true intention of the testator are the two main disputed points. The burden of proof should focus on the period before and after the making of the will, rather than providing general evidence of the testator's normal state of mind in daily life.

Q5: If the date of the will is only written as the year and month, is it still valid?

There are risks involved. Article 1134 requires that the year, month, and day be specified, as these date elements are crucial for assessing the testator's capacity and determining the precedence of multiple wills. In judicial practice, incomplete dates (e.g., only the year or month) are often deemed formal defects. Some courts may consider all available evidence to determine whether the defect can be remedied, but a significant proportion of such wills are ultimately deemed invalid. A safer approach is to draft a will with complete elements and specify the revocation of the previous will. If the elderly person has already passed away and the defect cannot be remedied, comprehensive evidence such as handwriting analysis, witness testimonies, and verification of the will's content against family facts should be collected. Different courts have varying standards, and outcomes vary from case to case. It is advisable to consult a lawyer as soon as possible.

If you are currently facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with the relevant evidence, to avoid missing the statutory time limit. →Legal services for inheritance·Attorney Yuan Hang·Beijing Henglue Law Firm
