I want to know whether it is effective to terminate the contract by SMS.

The termination of the contract by SMS is valid only if the parties reach an agreement through consultation or both parties agree to terminate the contract by SMS. Or there is a situation in which one party clearly indicates or indicates by its own behavior that it will not perform the main debt, and the parties can terminate the contract by SMS.

legal ground

Article 562 of the Civil Code in force according to 202 1 1.

The parties may terminate the contract if they reach an agreement through consultation.

The parties may agree on the reasons for one party to terminate the contract. When the reasons for the termination of the contract arise, the creditor may terminate the contract.

Article 563 of the Civil Code

In any of the following circumstances, the parties may terminate the contract:

(a) the purpose of the contract cannot be achieved due to force majeure;

(two) before the expiration of the time limit for performance, one party clearly indicated or indicated by his own behavior that he would not perform the main debt;

(three) one party delays the performance of the main debt and fails to perform it within a reasonable period after being urged;

(4) One of the parties delays the performance of debts or commits other breach of contract, which makes it impossible to achieve the purpose of the contract;

(5) Other circumstances stipulated by law.

For an indefinite contract whose content is to continue to perform debts, the parties may terminate the contract at any time, but they shall notify the other party before a reasonable time limit.
