Capital increase and share expansion can raise funds from old shareholders or people other than shareholders, but the funds raised cannot exceed the prescribed amount. For example, an unlisted joint-stock company cannot raise funds from an unspecified majority, which involves illegal fund-raising.
If the pre-registered capital of the joint-stock company is not in place, it will not affect the subsequent raised funds, and it is not necessary to require the pre-registered capital to be in place for subsequent capital increase and share expansion.
However, the premise is that according to the provisions of the articles of association of the joint-stock company, the funds stipulated in the articles of association should be in place, otherwise it will constitute a breach of contract, and the company has the right to sue the former shareholders and ask them to pay in place.
