[Direct answer]In the Beijing area, an expert assistant refers to a person who, upon the request of a party, has specialized knowledge and testifies in court to give opinions on professional issues. In medical disputes, their core roles include: helping parties understand the appraisal opinions and professional issues in medical records; providing targeted cross-examination of the appraisal opinions during the trial; and compensating for the patient's lack of medical knowledge and balancing the parties' ability to provide evidence. According to Article 79 of the Civil Procedure Law of the People's Republic of China (amended in 2023 and effective from January 1, 2024), parties may apply to the people's court to notify persons with specialized knowledge to appear in court; and according to Articles 83 and 84 of the Supreme People's Court's Several Provisions on Evidence in Civil Procedure (amended on December 25, 2019 and effective from May 1, 2020), parties may apply for one to two expert assistants to appear in court, and their opinions shall be deemed as the parties' statements. Expert assistants shall apply before the expiration of the time limit for providing evidence, and the expenses shall be borne by the applicant. They cannot replace appraisers. For the overall arrangements involving appraisal and rights protection, please refer to the details below.Legal services for personal injury and medical disputes.

I. Problem Background and Typical Scenarios

The professional threshold of medical disputes is mainly reflected in the appraisal opinions: the appraisal documents are full of medical terms, and the patients often cannot understand the description of faults, the deduction of causality and the proportion of causation. The cross-examination in the courtroom can only be generalized; the medical side is supported by professional teams, and the evidentiary ability of the two sides is inherently unequal. Typical scenarios include: dissatisfaction with the appraisal opinions, unexplained causes of death in patients who died without autopsy, blurred boundaries of responsibility for continuous treatment in multiple hospitals, disputes over the authenticity of medical records, and doubts about the proportion of causation. In these scenarios, introducing expert assistants to help the parties "understand" professional issues and provide effective cross-examination has become a common choice. The relevant rules can be referred toLegal services for personal injury and medical disputes.

II. Key points of contention

The controversy focuses on five points. Firstly, the legal nature of the expert assistants' opinions: they are regarded as the parties' statements according to the law, rather than appraisal opinions, and their probative force shall be comprehensively evaluated by the court based on the entire case. Secondly, the application threshold and the number of applicants: the parties may apply for one to two assistants, who must be proposed before the expiration of the evidence-presentation period and be notified by the court to appear in court. Thirdly, whether the appraisal opinions can be challenged: the parties may elaborate on the qualifications, procedures, and sufficiency of the basis, but the initiation of a re-appraisal still requires compliance with statutory circumstances. Fourthly, the burden of expenses: the applicant shall bear the expenses himself, which shall not be included in the appraisal fees and shall not be automatically borne by the other party if the applicant loses the case. Fifthly, the connection with the appraiser's appearance in court: the assistants' questioning and objections shall focus on the disputed points and avoid being aimless. In the judicial practice of Beijing, the appearance of expert assistants in court has become quite common in medical malpractice cases, and the specific procedures shall be subject to the arrangements of the accepting court.

III. Professional analysis by Henglue Lawyers

In a medical liability dispute handled by Attorney Yu Dawei, the defense and counterattack surrounding the appraisal opinion were fully demonstrated. On May 16, 2024, Zhao Dashan, an elderly patient, underwent a gastroscopic biopsy at A City Tumor Hospital for esophageal cancer follow-up and returned home. However, he suddenly vomited blood and was rushed to B County People's Hospital for rescue. Due to his critical condition, he was transferred to the First Affiliated Hospital of C Medical University, where he died on the afternoon of May 18th due to hemorrhagic shock and gastrointestinal bleeding. His wife, Liu Shufen, and three children sued three hospitals and applied for a judicial appraisal of "medical negligence and causality". The appraisal opinion concluded that B County People's Hospital failed to comprehensively evaluate the critical patient, failed to timely improve resuscitation treatment, lacked dynamic monitoring, and failed to use gastroscopy to identify the bleeding point. The error was found to have a causal relationship with "loss of survival opportunity", with a causal contribution of 50%. The defendant raised multiple objections, including the appraisal institution's lack of pathology qualifications, the unlawful determination of "loss of survival opportunity", the failure to provide expert information, and the lack of autopsy due to unclear cause of death. After the appraisal institution responded to each objection, the court accepted the appraisal opinion and determined that the hospital should bear 50% of the liability for compensation. This case shows that appraisal opinions are often the key to determining the outcome of the case, and the ability to cross-examine professional issues directly affects their probative value. Experts with medical knowledge backgrounds are an important assist to clients in this process.

5. Henglu Law Firm's Reminder

The expert assistant is not a "second appraiser". His opinions are regarded as statements of the parties, and the probative force of the opinions depends on whether the reasoning is sufficient and whether they can withstand cross-examination. Don't expect to overturn the appraisal opinions just by having the assistant attend the court hearing. Procedural objections, written agency opinions, and evidence reinforcement must be carried out simultaneously. It is far more valuable to use the assistant on key disputes than to have him attend the court hearing in a general way.

VI. Frequently Asked Questions

Q1: If I hire an expert witness, will I definitely win the lawsuit?

No. The opinions of expert assistants are legally regarded as statements of the parties, and the final judgment still depends on the overall evidence and the court's review of the appraisal opinions. If the appraisal opinions determine that the hospital is at fault and the causal relationship is established, the patient's claims are more likely to be supported; if it is determined that there is no fault, the causal relationship is not established, or the proportion of causation is very low, even if the expert assistants testify in court, the claims may only be partially successful. The outcome of the case depends on the facts, evidence, and legal application. No lawyer can unilaterally guarantee victory or defeat. Solid evidence and convincing arguments are the fundamental factors.

Q2: What materials do I need to prepare to apply for an expert assistant?

It mainly includes four categories: First, a written application form, stating the name of the professional who intends to apply for appearing in court, their professional background, and the professional issues they want to clarify; Second, professional competence materials, such as professional titles, practice experience, and academic achievements; Third, basic case materials, including medical records, examination and inspection reports, imaging data, and appraisal documents; Fourth, a list of dispute focuses, outlining the specific doubts about the appraisal opinions. The materials should be submitted before the expiration of the evidentiary period, and the court will review them and decide whether to notify the professional to appear in court.

Q3: How much does it cost for an expert witness to appear in court, and who bears the expenses?

There is no unified government pricing for expert assistants' fees. The fees are determined through negotiation between the parties and the professionals, and are charged on a per-case or per-stage basis, generally ranging from a few thousand yuan to tens of thousands of yuan, depending on the professional field and the time invested. The fees are borne by the applicant himself, and do not fall under the category of appraisal fees in litigation costs, nor are they automatically transferred to the other party if the applicant loses the case. Before entrusting the expert, it is necessary to clarify the scope of work, the number of times for reviewing the case files and appearing in court, and the charging method to avoid price increases during the process.

Q4: When will the expert assistants appear in court, and how long will the procedure take?

Experts assistants attend court hearings and cross-examinations as arranged by the court, representing the parties to express opinions on appraisal opinions or professional issues, and accepting questioning from judges and the opposing party. A single procedure usually lasts several hours. The application should be submitted before the expiration of the evidentiary period. After the court reviews and approves it, it will notify the experts to attend the hearing. Complex professional issues may require the experts to review the case files in advance, communicate with the attorneys, and prepare for several days to several weeks.

Q5: If I want to apply to be an expert witness, what should I do first?
