Generally speaking, companies have administrative seals, namely, official seal, financial seal and special seal for contracts. A contract can be stamped with the official seal or the contract seal, which has legal effect.

I. Difference and connection between the official seal and the special seal for contract (I) Difference: The official seal has the highest effect among all seals and is a symbol of legal person's rights. Unless there are special provisions in the law (such as stamping invoices), the official seal can represent the will of legal persons and sign contracts and other legal documents with high legal effect. All letters, official documents, contracts, letters of introduction, certificates or other company materials issued in the name of the company can use the official seal. The special seal for contract is used by the unit when signing the contract. It can represent the unit within the scope of signing, and the unit should bear the rights and obligations arising from it. In practical work, the official seal can be used instead of the special seal for the contract.

(2) Contact: As for the effectiveness of the special seal and the official seal of the contract, they are actually the same in the use process and judicial practice, and have the same legal effect as contracts and agreements. According to the contract law, signature or seal is a selective relationship, that is, signature or seal or both. These three situations have the same significance for the establishment of the contract. Because the seal is easy to be forged, the nominal owner of the seal (that is, the owner of the seal with a name on it) is easy to be separated from the actual controller, so the probative force of the seal is essentially lower than that of the signature. More attention should be paid to signature in trading activities, because the certainty of the relationship between signature and signer is far greater than that between seal and signer. As long as the other party signs in person, the validity and probative force of his signature can be guaranteed to a considerable extent.

Two. Article 32 When a contract is concluded, if the parties conclude the contract in the form of a contract, the contract shall be concluded when both parties sign or seal it. Hospitals should keep all original medical records for a certain number of years, and good hospitals can exceed 100 years, such as Union Medical College Hospital. Medical records are wealth. You can go to the hospital medical record room for consultation. Of course, you can't tell him the purpose of your search, otherwise he will set obstacles for you artificially. You can say that it is to check the medication and do medical insurance.
