1. The original articles of association need to be signed by all shareholders. If a "shareholder" does not sign, it means that he has no intention to initiate the establishment of a company. The articles of association shall not be effective to the shareholders unless they approve it afterwards.

2. When registering a company, the company registration authority shall conduct a formal examination of the signatures of shareholders.

3. If a "shareholder" does not sign, it is an obvious formal defect; Registration is still carried out at this time, and the company registration authority has failed to perform its duties correctly, which is at fault. At this point, the "shareholders" may request cancellation of company registration. If damage is caused to the obligee, the obligee may also request the company registration authority to make compensation.

4. If the "shareholder" is only signed by someone else under a pseudonym, it can't be judged by formal examination. After registration by the company registration authority, a person registered as a shareholder under a pseudonym may request cancellation of shareholder registration, but the registration authority is not at fault and cannot ask the registration authority to compensate for the losses.

Second, the subsequent articles of association

1. The subsequent articles of association, that is, the original articles of association modified, do not need to be signed by all shareholders.

2. What is needed is that the company holds a shareholders' meeting, and with the consent of shareholders representing more than two thirds of the voting rights, the articles of association are amended to form an amendment or revised articles of association.

Shareholders who agree to amend the Articles of Association shall sign the resolution of the shareholders' meeting, but it is not necessary to sign the amended Articles of Association.

3. According to Article 27 of the Regulations on the Administration of Company Registration, if the company's change of registration involves the revision of the company's articles of association, it shall submit the revised articles of association or amendments to the articles of association signed by the company's legal representative.

In other words, only the signature of the legal representative is required.

In addition, it is sometimes unrealistic to require all shareholders to sign the revised articles of association, because some shareholders may vote against it at the shareholders' meeting, they will not agree to amend the articles of association, and naturally they will not sign the articles of association.
