Legal analysis
A letter of guarantee is a letter of commitment and has the legal effect of a contract. As long as it is an expression of the true meaning of the other party, it is not imposed or coerced, and it does not violate the law. It is a valid contract or commitment, which can at least play a role of proof. If the other party makes another mistake, it will be at a disadvantage in property division and child support. Even if you don't promise, you will suffer losses in law. Commitment, that is, the fact and content of commitment are unified with the legal provisions, which can be completely recognized as effective behavior. There is a legal basis for the parties and the other party to fulfill their commitments. However, if this guarantee is not notarized, the promisee may be completely mistaken, saying that this is not his true meaning, but a statement made under duress. In fact, this situation will be inferred and solved by legal procedures. A letter of guarantee is a letter in the name of a collective or an individual, with a relatively tough attitude, expressing the determination to make a guarantee to a superior organization, leader or individual. To a certain extent, it forms a constraint and spur on the oath. Therefore, it has the characteristics of taking an oath. Letter of guarantee refers to the guarantor of the person who has been released on bail pending trial in criminal cases, or the litigation documents made by the relevant witnesses and experts who testify in court and sign the letter of guarantee to the people's court.
