[Direct answer]The materials can be divided into four categories. The first category is the main materials: the identity certificates of the plaintiff and all defendants, and the service address information. The second category is the relationship materials: the death certificate of the decedent and the proof of kinship, which are used to determine the order of inheritance; Article 1127 of the Civil Code of the People's Republic of China stipulates that the first order of inheritance is the spouse, children, and parents. The third category is the inheritance materials: real estate ownership certificates, deposit and financial management certificates, vehicle registration, and company equity certificates, etc. The fourth category is the will materials: the original will and the bequest support agreement (if any).

I. Problem Background and Typical Scenarios

The common difficulties encountered by litigants when filing a lawsuit include incomplete materials: not knowing all the accounts of the decedent, difficulty in proving kinship due to the passage of time, property ownership registered under the name of someone other than the decedent, or omission of certain heirs. These issues may result in the case being dismissed upon filing or the need to add additional litigants after the trial begins. Beijing area courts are particularly strict in reviewing the filing of inheritance cases, requiring clear subject identification, clear legal relationships, and materials corresponding to the claims. Moreover, such issues often involve multiple parties and complex legal relationships. Clarifying the positions, responsibilities, and applicable rules of all parties is a prerequisite for resolving the dispute. The more complete the materials and clearer the timeline, the greater the initiative litigants can grasp in subsequent negotiations and litigation. When conducting a detailed analysis, it is recommended to take the timeline as the main line and correspond contracts, certificates, transaction records, and relevant legal bases one by one, forming a clear processing framework to facilitate the determination of the order and feasibility of various claims.

II. Key points of dispute

First, how to specify the scope of heirs, and whether it involves subrogated succession or transfer of succession. Second, how to prove kinship relationships, especially in cases of long-standing or cross-regional situations. Third, how to define the scope of the estate and handle properties that are difficult to provide evidence for. Fourth, how to claim and provide evidence when the original will is missing. Fifth, whether the co-owned shares need to be first separated before being included in the claims. Sixth, whether the order of rights claims and preliminary procedures have been met. Seventh, whether the authenticity, legality, and relevance of evidence can withstand scrutiny. Eighth, how to balance the interests of third parties and the public. Ninth, how to trade off the advantages and disadvantages of efficiency and outcomes between settlement, mediation, and adjudication. In addition, attention should also be paid to whether the form of evidence is legal, whether key facts can be corroborated, and the differences in cost, time, and feasibility of different handling methods. On this basis, the priority path to be pursued can be determined.

III. Professional analysis by Henglue Law Firm

The practical experience of Henglue Lawyers is that the integrity of the filing stage of inheritance cases directly determines the subsequent efficiency. In practice, we first reconstruct the kinship relationship based on household registration files, unit files, and the marriage registration materials of the decedent; then sort out the list of inheritance through account inquiries, real estate registration, and social security information; for properties that cannot be confirmed temporarily, we can apply for investigation or make separate claims in litigation. The claim should clearly specify the specific property and shares to be divided to avoid vague expressions. The most easily overlooked aspects in material preparation are the full listing of defendants and the division of jointly owned property: omitting the listing of heirs often results in the mediation plan not covering all right holders, and failing to divide the property in advance may lead to errors in calculating shares. For wills, if the original is missing, we should try to supplement it with witnesses, copies, and other supporting evidence, but the effectiveness of the will is at risk and requires careful evaluation.

5. Henglue Law Firm's Reminder

Firstly, the list of defendants is a basic requirement for inheritance litigation. Omitting it will slow down the entire process. Secondly, the proof of kinship should be obtained from official archives as much as possible, and witness statements should only be used as supplementary evidence. Thirdly, the risk of the original will being lost is relatively high, so it should be fixed as soon as possible. Fourthly, the jointly-owned property should be divided before distribution to avoid errors in calculating shares.
