Legal subjectivity:

1. When signing a contract, the contract must be signed by both parties. The contract requires signatures from both parties and needs to be determined based on the actual situation. If the parties conclude the contract in the form of a contract, the contract is established when both parties sign or seal it. If the parties conclude a contract in the form of letters, data messages, etc., they may require a confirmation letter to be signed before the contract is established. The contract is formed when the confirmation letter is signed. 2. According to Article 490 of the 2021 Civil Code, if the parties conclude a contract in the form of a contract, the contract is established when both parties sign, seal, or fingerprint. Before signing, sealing or fingerprinting, one party has performed its main obligations and the contract is established when the other party accepts it. Laws and administrative regulations stipulate or the parties agree that a contract should be concluded in written form. If the parties do not use written form but one party has performed its main obligations and the other party accepts it, the contract is established. Legal objectivity:

Article 502 of the Civil Code

A contract established in accordance with the law shall take effect from the time of its establishment, but the law provides otherwise or Unless otherwise agreed by the parties.

In accordance with the provisions of laws and administrative regulations, if the contract should be approved and other procedures should be followed, the provisions shall be followed. If the failure to go through approval and other procedures affects the effectiveness of the contract, it will not affect the effectiveness of the contract's obligation clauses such as submission for approval and related clauses. If the party that should go through the application approval and other procedures fails to perform its obligations, the other party may request that it bear liability for violating such obligations.

In accordance with the provisions of laws and administrative regulations, if the modification, transfer, termination, etc. of a contract require approval and other procedures, the provisions of the preceding paragraph shall apply.
