Is the undertaking signed by the property owner useful?

A letter of commitment means that the promisor fully agrees with the offeror's offer and expresses it in writing. Usually, a contract is required to be concluded in writing, and its promise must also be in writing. . For example, Article 2-20 1 of Volume II of the United States Uniform Commercial Code stipulates that any contract for the sale of goods exceeding $5,000 must be concluded in writing unless otherwise stipulated in the code, otherwise the court cannot be required to enforce it, and the court will not accept oral evidence of such contracts in principle.

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 is a reflection of the true wishes 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 content 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 interests of others. The promisor can only dispose of what he has the right to dispose of, but not infringe upon the legitimate 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 a letter of commitment that expresses the true meaning of the parties concerned and does not violate the relevant provisions of the law or infringe upon the interests of others is valid and will be protected by law.
