Laws, regulations and relevant business guidelines do not clearly stipulate that lawyers' letters must be stamped with the official seal of the law firm, but only stipulate that lawyers should be entrusted by the law firm to undertake business. Although the lawyer's letter is not stamped with the official seal of the law firm, it states that the law firm accepts the entrustment of the parties and has the lawyer's signature, which is considered to be effective in general judicial practice, but from the normative point of view, it is more appropriate to have the official seal.

Such a lawyer's letter has no legal effect, and it must be sealed by the law firm and signed by the lawyer.

And according to the content, the interest has exceeded the highest standard stipulated by the state.
