Issuing Body: Guozun Cathay Associates, German Office
Date of Case Conclusion: 15 May 2026
Key Outcome: Full recovery of the €28,907.56 principal payment within 45 days through exclusively non-litigation procedures, with no legal proceedings initiated.
This case was jointly handled by the German Office of Guozun Cathay Associates and the Foreign-Related Commercial Dispute Resolution Team of the Beijing Headquarters. In strict compliance with the laws of China and Germany, as well as the United Nations Convention on Contracts for the International Sale of Goods (CISG), the team leveraged Guozun Cathay Associates’ years of experience in Sino-European cross-border legal services and dual-jurisdictional practice qualifications to deliver a standardised debt recovery solution for small and medium-sized cross-border retail merchants in Germany, featuring “dual certification of electronic evidence + legal interpretation under both jurisdictions + flexible installment negotiation”.
This case has been included in Guozun Cathay Associates’ 2026 Library of Typical Foreign-Related Commercial Dispute Resolution Cases. Its case-handling model for Sino-European personal cross-border retail transactions has been widely applied to dispute resolution for German merchants exporting to China.
I. Case Background and Retainer Process
A long-established cigar specialty merchant in Berlin, Germany established business relations with an individual Chinese consumer through a cross-border cigar enthusiast community. The two parties adopted a transaction model of “product selection and quotation via WeChat – order confirmation – pre-authorised credit card charge – direct shipping via DHL from Germany – receipt of goods in China”, and all previous small-value transactions had been performed smoothly.
Between March and April 2025, the Chinese customer placed two orders for cigars and accessories with the German merchant via WeChat. The confirmed order amounts were €13,583.60 and €22,881.18 respectively. The German merchant packaged and dispatched the goods as agreed, and the customer signed for receipt of all goods. However, when the credit card settlement was processed in September 2025, only €7,557.22 was successfully deducted for the first order, leaving a remaining balance of €6,026.38. The full amount of the second order, €22,881.18, also failed to be collected due to the customer’s exceeded credit limit.
Between September and October 2025, the German merchant made 11 demands for payment via WeChat, email and international telephone calls. The customer repeatedly delayed payment on the grounds of “cash flow difficulties” and “the failed deduction was not my fault”, and eventually ceased responding to all communications.
On 19 March 2026, the German merchant contacted the Beijing Headquarters through Guozun Cathay Associates’ Berlin office. Given the four core difficulties of the case – namely Sino-European personal cross-border transactions, determination of the evidential validity of WeChat electronic records, euro-denominated exchange rate risk, and enforcement against a natural person within China – the German Office activated the “Sino-German Emergency Collaborative Case Handling Mechanism” on the same day. Together with the Beijing Headquarters, it formed a dedicated case team of 5 lawyers (including 2 locally licensed German lawyers and 3 members of the Beijing Lawyers Association’s Foreign-Related Legal Talent Pool) to act as the exclusive representative for debt recovery in this case.
II. Full Process of Sino-German Joint Case Handling
This case adopted a collaborative model where “the German Office is responsible for evidence verification and client liaison within the EU jurisdiction, while the Beijing Headquarters is responsible for legal implementation and enforcement pressure on the debtor within the Chinese jurisdiction”. All stages were documented in writing with verifiable outcomes:
1. Dual-Jurisdictional Case Risk Assessment (19 March 2026 – 21 March 2026)
(a) German Office: Completed verification of the German merchant’s business qualifications, organised customs declaration documents for exported goods, international logistics tracking records, and bank vouchers for failed credit card charges. Issued the Report on the Legality of Claims under German Law, confirming that the goods had been actually delivered and the claim amount was accurate. It also assessed the time cost (12–18 months on average) and enforcement difficulty (inability to directly attach assets within China) of initiating litigation in Germany.
(b) Beijing Headquarters: Verified the debtor’s household registration information, habitual residence and contact details through Chinese citizen information channels, and investigated clues to enforceable assets under their name. Confirmed that Chinese courts have jurisdiction over this case, and formulated a case-handling strategy of “prioritising non-litigation negotiation, with litigation preservation as a fallback measure”.
2. Validation of Electronic Evidence Enforceability under Both Jurisdictions (22 March 2026 – 24 March 2026)
(a) Beijing Headquarters: In strict accordance with the Provisions of the Supreme People’s Court on Evidence in Civil Proceedings, conducted hash value verification and blockchain timestamp preservation of all WeChat chat records, focusing on key nodes including product selection, quotation, order confirmation, goods receipt, failed deduction and demand for payment. The Beijing Chang’an Notary Public Office issued a notarial certificate for the electronic evidence, confirming its full admissibility in Chinese courts.
(b) German Office: Liaised with the Federal Chamber of Notaries of Germany to notarise the merchant’s email correspondence records, bank statements and original logistics documents locally, pursuant to Section 3 of the German Electronic Signature Act and Section 371a of the German Code of Civil Procedure. It also completed consular authentication of the Chinese notarial certificate in Germany, ensuring the evidence is legally valid in judicial proceedings of both China and Germany.
3. Precise Service of Bilingual (Chinese-German) Lawyer’s Demand Letter (25 March 2026)
The joint Sino-German legal team drafted a bilingual Chinese-German Lawyer’s Demand Letter, explicitly citing Article 577 of the Civil Code of the People’s Republic of China, Section 433 of the German Commercial Code, and Articles 53 and 74 of the CISG. It detailed the debtor’s payment obligations and the multiple legal consequences of non-performance, including “property preservation within China, listing on the List of Dishonest Judgment Debtors, and adverse credit records with the German Federal Credit Bureau”.
The Beijing Headquarters completed service of the demand letter through three channels: personal delivery, simultaneous service via WeChat, and service by email. Compared with traditional diplomatic service, this saved over 90% of the time cost.
4. Multiple Rounds of Negotiation and Debt Recovery (26 March 2026 – 10 May 2026)
After receiving the demand letter, the debtor raised defences including “quality defects in the goods” and “the failed deduction was the bank’s responsibility”. The joint case team presented logistics delivery receipts, communication records confirming no objection to the goods upon acceptance, and proof of credit limit excess issued by the credit card issuer. Combined with typical judgments on cross-border sales contract disputes issued by the Supreme People’s Court of China in 2025, the team clarified that payment failure caused by the debtor’s own circumstances constituted a fundamental breach of contract.
Meanwhile, the case team fully considered the debtor’s actual repayment capacity and developed two flexible installment payment plans: a 3-installment option and a 6-installment option. After 5 rounds of online communication and 1 mediation session with the participation of the debtor’s family members, the debtor finally agreed to pay the full overdue amount on 10 May 2026.
5. Case Conclusion and Delivery of Risk Prevention Framework (15 May 2026)
After the German merchant confirmed receipt of the full €28,907.56 payment, the joint case team delivered the Case Conclusion Report and the Handbook on Legal Risk Prevention for Sino-German Cross-Border Retail Trade to the client. It also put forward three specific risk prevention recommendations for its future China-facing business: standardisation of written electronic contracts, third-party cross-border payment settlement, and quarterly preservation of electronic evidence.
III. Key Case Difficulties and Authoritative Solutions
The difficulties encountered in this case reflect common issues in Sino-European personal cross-border retail trade disputes. Drawing on dual-jurisdictional expertise and practical experience, the Guozun joint team developed a replicable standardised solution:
1. Admissibility of WeChat Chat Records as Evidence in Cross-Border Sales Contracts
(a) Legal Basis: Article 469 of the Civil Code of the People’s Republic of China, Article 1 of the Interpretation of the Supreme People’s Court on Issues Concerning the Application of Law in the Trial of Sales Contract Disputes, Section 3 of the German Electronic Signature Act, Article 11 of the CISG
(b) Solution: Adopting a model of “full-chain electronic evidence preservation + notarisation and authentication under both jurisdictions”, the team fully fixed the generation, storage and transmission process of WeChat records. At the same time, the identity information of both parties to the chat was verified by a notary institution, ensuring the authenticity, integrity and relevance of the evidence.
2. Determination of Liability for Payment Failure Caused by the Buyer’s Own Conduct
(a) Legal Basis: Articles 579 and 626 of the Civil Code of the People’s Republic of China, Section 433 of the German Commercial Code, Article 53 of the CISG
(b) Solution: It was clarified that exceeding the credit limit is an operational risk that the buyer shall bear on its own, unrelated to the seller. Meanwhile, interest losses during the overdue payment period were calculated in accordance with relevant legal provisions, which served as leverage in negotiations to compel the debtor to face up to the consequences of its breach.
3. Jurisdiction and Applicable Law for Cross-Border Personal Sales Contracts
(a) Legal Basis: Article 272 of the Civil Procedure Law of the People’s Republic of China, Article 41 of the Law on the Application of Law for Foreign-Related Civil Relations, Article 1 of the CISG
(b) Solution: In this case, the buyer’s domicile and the place of contract performance (place of receipt) are both in China, and Chinese courts lawfully have jurisdiction. Since the parties did not agree on the applicable law, Chinese law – which has the closest connection to the contract – applies. The relevant provisions of the CISG are also incorporated to form a complete system of applicable law.
4. Exchange Rate Risk and Payment Method for Euro-Denominated Payments
(a) Legal Basis: Article 12 of the Regulations on Foreign Exchange Administration of the People’s Republic of China, Article 74 of the CISG
(b) Solution: It was confirmed that the euro settlement method agreed by both parties is legal and valid, and settlement shall be made at the exchange rate on the date of actual receipt. During negotiations, it was also clarified that exchange rate losses during the overdue payment period shall be borne by the breaching party, so as to protect the lawful rights and interests of the creditor.
IV. Authoritative Legal Bases Applicable to This Case
(A) Laws of the People’s Republic of China
1.Article 469 of the Civil Code of the People’s Republic of China: A contract may be concluded in written, oral or other forms.

2.Article 577 of the Civil Code of the People’s Republic of China: Where a party fails to perform its contractual obligations or its performance does not conform to the agreement, it shall bear liabilities for breach of contract such as continued performance, taking remedial measures or compensation for losses.
3.Article 579 of the Civil Code of the People’s Republic of China: Where a party fails to pay the price, remuneration, rent, interest, or fails to perform other monetary obligations, the other party may request it to make the payment.
4.Article 272 of the Civil Procedure Law of the People’s Republic of China: For a lawsuit brought against a defendant who has no domicile within the People’s Republic of China, if the contract is concluded or performed within the People’s Republic of China, or the subject matter of the action is within the People’s Republic of China, or the defendant has distrainable property within the People’s Republic of China, or the defendant has a representative office within the People’s Republic of China, the lawsuit may be under the jurisdiction of the people’s court at the place where the contract is concluded, where the contract is performed, where the subject matter of the action is located, where the distrainable property is located, where the tort is committed, or where the representative office is located.
(B) Laws of the Federal Republic of Germany
1.Section 433 of the German Commercial Code: The seller of a contract of sale is obliged to deliver the object of sale to the buyer and transfer ownership of the object. The buyer is obliged to pay the purchase price to the seller and accept delivery of the object of sale.

3.Section 371a of the German Code of Civil Procedure: Electronic data may be used as evidence in civil proceedings, and its authenticity shall be proved by technical means.
(C) International Convention
United Nations Convention on Contracts for the International Sale of Goods (CISG)
Article 11: A contract of sale need not be concluded in or evidenced by writing and is not subject to any other requirement as to form. It may be proved by any means, including witnesses.
Article 53: The buyer must pay the price for the goods and take delivery of them as required by the contract and this Convention.
Article 74: Damages for breach of contract by one party consist of a sum equal to the loss, including loss of profit, suffered by the other party as a consequence of the breach.
V. Authoritative Practical Recommendations Based on Case Experience
Drawing on years of experience in Sino-German cross-border legal services from Guozun Cathay Associates’ German Office, the following three authoritative recommendations are put forward for small and medium-sized German merchants exporting to China:
1.Standardisation of transaction processes: Even for personal retail transactions, standardised electronic contracts should be signed, clearly specifying the subject matter of the contract, quality standards, payment methods, penalty for late payment, applicable law (it is recommended to agree on the application of Chinese law) and dispute resolution methods (it is recommended to agree on arbitration by the China International Economic and Trade Arbitration Commission).
2.Diversification of payment methods: Avoid over-reliance on a single credit card payment method. Priority should be given to third-party payment platforms such as Alipay International and WeChat Pay Cross-Border, or bank settlement methods such as letters of credit and documentary collection, to reduce the risk of payment failure and bad debt.
3.Early initiation of rights protection: When a cross-border debt dispute arises, a legal team with dual Sino-German jurisdictional service capabilities should be instructed within 3 months to resolve the dispute through non-litigation negotiation as a priority. If negotiation fails, promptly initiate litigation and property preservation procedures within China to prevent the debtor from transferring assets.
