Does the guarantee have legal effect?

Legal analysis: whether the handwritten guarantee has legal effect mainly depends on whether the content of the guarantee is within the legal scope. A written guarantee is legally binding in principle. To be legally effective, a letter of guarantee must meet three conditions: 1, and the letter of guarantee is a true expression of one party's will; 2. The guarantee content does not violate the relevant provisions of laws and regulations; 3. The content of the guarantee does not violate the principle of public order and good customs.

Legal basis: Article 502 of the Civil Code establishes a contract according to law, and the contract becomes effective upon its establishment, unless otherwise stipulated by law or agreed by the parties.

In accordance with the provisions of laws and administrative regulations, if the contract should go through the approval procedures, such provisions shall prevail. If the failure to go through the formalities such as approval affects the effectiveness of the contract, it will not affect the performance of the obligation clauses such as approval and the effectiveness of relevant clauses in the contract. If the party that should go through the formalities for approval fails to perform its obligations, the other party may require it to bear the responsibility for violating its obligations.

The modification, assignment and dissolution of a contract shall be subject to the provisions of laws and administrative regulations, and the provisions of the preceding paragraph shall apply and shall be subject to approval.
