Chinese companies use chops for contracts, corporate filings, banking, invoices and other business processes. A chop can be powerful evidence that a company approved a document, but the physical impression is not the entire legal analysis. Courts can examine the signer’s representative or agency authority, the parties’ conduct and any mandatory approval rules, including where a seal is disputed, unofficial or forged.
Companies should maintain a documented seal-control system covering creation, registration where applicable, custody, approval, use logs, electronic seals, handovers, loss and destruction. Splitting control among responsible personnel and reconciling each use to an approved transaction reduces fraud and business-continuity risk.
Direct answer
Inventory every physical and electronic seal, identify its purpose and custodian, and require documented approval before use. Link each impression to the complete signed document and preserve the request, authorization, counterparty and return record. Keep corporate authority, signatures and any legally required internal approvals aligned with the seal.
Do not assume that possession of the company chop creates unlimited authority or that a disputed chop automatically defeats a contract. Legal effect depends on the document, the actor’s authority, the counterparty’s position, applicable approval rules and evidence of the transaction.
Common types of chops
A company may use a principal company chop and specialized chops for contracts, finance, invoices, customs, legal representative matters or other regulated workflows. Banks and authorities may require particular seals, specimens, signatures or electronic credentials.
Terminology and filing practice vary by location and institution. Create a register recording the official name, image or specimen, unique identifier where available, issuing authority or maker, permitted purpose, custodian, storage, effective date and status. Do not let an informal departmental stamp be mistaken for a company-authorizing seal.
Legal effect is not purely mechanical
A genuine company chop is important evidence of corporate assent. It is not a substitute for asking whether the person who negotiated or executed the document had legal-representative, actual or apparent authority and whether the transaction required a corporate resolution or another statutory approval.
Supreme People’s Court guidance and cases distinguish the underlying expression of agreement from the act of affixing a seal. Where a company disputes a non-filed, privately made or forged seal, a court can focus on representative or agency authority and the surrounding transaction. Conversely, a genuine chop does not necessarily cure a transaction that violates mandatory authority or approval restrictions.
For material contracts, verify both the seal and the human authority chain. Preserve board or shareholder approvals, powers of attorney and scope limitations where relevant.
Seal policy and authority matrix
The policy should state:
- which seal is used for each document type;
- who may request, approve, affix and witness use;
- value and risk thresholds for legal or finance review;
- prohibited uses, including blank or incomplete documents;
- offsite-use and emergency procedures;
- electronic-seal and credential controls;
- record retention and audit rules; and
- incident, suspension and replacement procedures.
Separate request, approval and custody where staffing allows. A custodian should verify the approved final version, not decide whether a transaction is commercially acceptable.
Contract execution
Before sealing, confirm counterparty identity, contracting entity, final document version, signature blocks, schedules, governing language and internal approval. Stamp only the agreed locations and preserve a complete executed copy. For multi-page documents, follow the transaction’s execution requirements and local practice rather than relying on a page-edge seal as a universal cure.
Record amendments, terminations, guarantees, security documents and side letters as separate transactions. A procurement or sales team should not reuse approval from the original agreement for a materially different document.
Blank documents and extracted signature pages
Never stamp blank paper, incomplete agreements, unattached signature pages or editable templates. These practices create serious evidentiary and fraud risk. If exceptional operational circumstances make remote execution necessary, use controlled electronic signing or an approved final hash/version workflow.
The use log should identify the full document, version, number of originals, pages, date, recipient and return or dispatch evidence. Store the executed instrument with its approval record.
Custody and physical security
Keep chops in controlled storage with named primary and backup custodians. Use access records, dual control for high-risk seals, periodic counts and unannounced audits. Avoid concentrating the company chop, legal-representative chop, bank tokens, passwords and cheque materials with one person.
Custodian changes require a witnessed handover listing each seal and outstanding offsite use. Suspend former access immediately. During management conflict, do not resolve custody through self-help that risks violence, evidence destruction or operational paralysis; obtain company and dispute advice.
Bank, finance and invoice controls
Bank mandates frequently combine seals, signature specimens, tokens and authorized-person records. Reconcile these to current corporate authority and remove departed personnel promptly. Require dual approval for payment instructions and independently confirm account changes.
Invoice chop use should match tax and invoicing systems. Finance should reconcile issued invoices, voids and seal use. A seal policy cannot replace tax-platform access control or bank verification.
Electronic seals and digital credentials
Electronic execution can be valid under applicable electronic-signature and contracting rules, but the evidence model differs from a scanned image of a chop. Identify the trusted service, certificate, signatory authentication, timestamp, document integrity and audit trail.
Protect certificate keys, platform administrators, mobile devices and recovery channels. A pasted seal image offers little assurance by itself. Preserve the native electronic record and validation evidence, not only a PDF printout.
Counterparty verification
For important transactions, compare the counterparty’s registered name and unified social credit code, check the signatory and authority, and confirm material account or address changes independently. A public registration database may not show every seal specimen, and a “registered chop” representation should not replace due diligence.
Red flags include inconsistent entity names, pressure to use a personal account, unexplained seal variations, refusal to provide authority evidence, detached signature pages and documents delivered only by an unknown intermediary.
Loss, theft or unauthorized use
On discovering a missing or misused chop:
- Secure remaining seals, documents, credentials and access logs.
- Preserve CCTV, messages, approvals and system evidence.
- Identify potentially affected documents and counterparties.
- Suspend relevant bank or platform access where justified.
- Notify management, legal, compliance and insurers.
- Assess police, public notice, authority and replacement procedures.
- Communicate carefully so warnings do not concede or repudiate valid obligations.
Do not destroy duplicate or disputed seals before evidence is preserved. Replacement procedures and the legal effect of past use require location- and fact-specific advice.
Management disputes and exit handover
Chop custody often becomes contested when a legal representative, director, shareholder or employee leaves. The company should plan handover through resolutions, employment processes, bank and registry changes, credential resets and a documented inventory.
The right to possess a physical seal and the power to bind the company are related but not identical. A corporate-control dispute may require preservation, return-of-property, governance and registration remedies. Avoid assuming that whoever holds the chop controls the company as a matter of law.
Audit checklist
- Complete physical and electronic seal register.
