Legal analysis
The letter of commitment is actually a contract, and of course it has legal effect. However, an effective undertaking must meet the following three conditions at the same time: 1, which reflects the true meaning of the parties. The content of the letter of commitment shall be the expression of the true meaning of the parties, and shall not be forced, threatened, lured or deceived. 2. No violation of relevant laws and regulations. The contents of the letter of commitment must comply with the provisions of the law and cannot violate the prohibitive provisions of laws or administrative regulations, otherwise it may lead to the invalidity of the letter of commitment. 3. Do not infringe upon the rights and interests of others. The promisor can only dispose of what he has the right to dispose of, and shall not infringe upon the legitimate rights and interests of others. In short, whether the commitment letter has legal effect mainly depends on whether the commitment letter meets the above three conditions. Of course, in practice, only the letter of commitment that the parties really mean, does not violate the relevant provisions of the law and does not infringe upon the rights and interests of others is also valid and will be protected by law.
