How long does it take to change the stock right need to be answered from two levels. From the point of view of the substantial change of equity, the change of equity has been completed since the signing of the Equity Transfer Agreement, and the company has registered the changed shareholders in the company's register of shareholders. Judging from the industrial and commercial changes of registered shareholders, the company needs to submit relevant materials to the industrial and commercial bureau for approval, and the equity will change. This cycle is generally about 5 working days from the date of submission of materials for approval. However, it should be reminded that: 1, failure to register for industrial and commercial change does not invalidate the equity transfer contract. General contracts come into effect when signed by both parties, but for special shares such as state-owned shares, they need to be approved by the competent authorities before they come into effect. 2. Industrial and commercial change registration is not a valid requirement in changes in equity. When the equity transfer contract comes into effect and is registered in the register of shareholders by the company, the transferee obtains the equity. If the registration of industrial and commercial change fails, shareholders have the right to request the company to handle the industrial and commercial change, and have the right to request the transferor to provide assistance. 3. Without the industrial and commercial change registration, it is not allowed to confront a bona fide third party. For those who have not gone through the registration of equity change, the third party has the right to trust the authenticity of the registered items, and a bona fide third party may require the original shareholders to bear the responsibility based on the records of industrial and commercial registration.
