Secondary Seal Execution Authority in Chinese Commercial Contracts
Enforcing Chinese commercial contracts requires executing agreements with PSB-registered official company seals and legal representative signatures.
Judicial Forensic Seal Appraisal
Meaning
Technical evidentiary examinations performed by certified experts determine the authenticity and origin of a physical impression made by a company seal. Judicial forensic seal appraisal serves to identify whether a stamp on a contract or document was made by the genuine official seal of an enterprise. It governs the resolution of disputes where a party claims a signature or seal was forged or used without authorization.
The process stops applying if the physical document is unavailable or if the impression is too faint for a meaningful comparison. It requires the use of microscopic analysis, spectral imaging and comparative measurements. This mechanism provides the courts with a scientific basis for deciding cases of suspected corporate fraud.
Successful appraisal can invalidate a multi-million dollar contract or confirm a disputed obligation.
Appraisal Mechanism
Comparative analysis between the questioned impression and a known genuine sample is the primary method used in this procedure. Under judicial forensic seal appraisal, the expert examines the fine details of the seal’s characters, borders and any unique defects. These defects, caused by wear and tear or manufacturing imperfections, act as “fingerprints” for a specific seal.
The expert uses high-resolution photography and specialized software to overlay the questioned and genuine impressions. Any discrepancy in the dimensions, the spacing of the letters or the thickness of the lines is documented. This process also includes an analysis of the ink used, which can be checked for chemical consistency and age.
The expert then issues a formal report that states the probability of a match. This report is a critical piece of evidence in the litigation process.
Forgery Detection
Identification of sophisticated forgeries requires the use of advanced forensic tools and a deep knowledge of seal production techniques. Under judicial forensic seal appraisal, experts look for signs of “digital imitation” where a seal is scanned and then printed or engraved using a computer. These forgeries often lack the subtle pressure variations and ink pooling characteristic of a physical stamp.
The expert also checks for “transfer forgeries” where a genuine impression is lifted from one document and moved to another. This is often revealed by the presence of foreign fibers or a lack of ink penetration into the paper. The direction of the ink strokes and the presence of any underlying pencil marks or indentations are also scrutinized.
By identifying these techniques, the appraiser can provide a clear explanation of how the fraud was committed. This information is vital for the court to understand the intent and the method of the forgery.
Standard Application
Administrative rules set by the Ministry of Justice govern the qualifications of the appraisers and the standards for the forensic laboratories. Under judicial forensic seal appraisal, only institutions with a valid forensic appraisal license can provide evidence that is admissible in court. The appraisers must follow the SF/Z JD0102002-2010 standard or its successors to ensure the consistency of the results.
This standard specifies the number of comparison samples required and the criteria for making a positive identification. If the appraisal is contested, the court may appoint a second institution to perform a re-appraisal. The boundary of the appraisal is limited to the physical characteristics of the seal impression.
It does not determine the legal authority of the person who applied the seal or the validity of the contract itself. These legal questions are left for the judge to decide based on the totality of the evidence.
