Meaning
Transactional security practices require both the physical application of a corporate seal and the handwritten signature of a legal representative. Adopting dual factor execution reduces the risk of internal fraud where a seal might be used without proper executive oversight. While the law often accepts the seal alone, many banking and high value procurement contracts mandate both markers to establish definitive intent.
Signature Requirement
The presence of a personal signature alongside the corporate chop serves to bind the individual accountability of the signer to the institutional act. Under dual factor execution, a document that lacks the signature of the authorized person may be flagged as incomplete by compliance departments even if the seal is genuine.
Institutional Security
Manufacturing plants and logistics firms use this method to separate the power of seal custody from the power of signing authority. Because the person holding the stamp is rarely the person authorized to sign for the firm, dual factor execution prevents a single point of failure in the contract approval chain. This separation of duties is a standard requirement for international audits and internal control frameworks.
Evidentiary Weight
Courts in many jurisdictions view the combination of a physical stamp and a wet ink signature as the strongest evidence of a valid agreement. This level of proof is particularly important in disputes where a company claims that its seal was stolen or used without permission.
