Check Articles of Association (AOA): Review the company's Articles of Association to ensure compliance with any specific provisions regarding the increase of paid-up capital.

Convene Board Meeting: Convene a meeting of the Board of Directors to propose the increase of paid-up capital. Prepare and circulate the agenda along with necessary documents to the board members in advance of the meeting.

Pass Board Resolution: During the board meeting, discuss and approve the proposal for increasing the paid-up capital. Pass a resolution by a majority vote of the directors present and voting. Specify the details of the proposed increase, including the amount of increase and any related matters.

Allotment of Shares: Determine the method of increasing the paid-up capital, such as issuing new shares, rights issue, bonus issue, or conversion of debentures or loans into shares. Allot the newly issued shares to existing shareholders or to new shareholders as per the applicable method.

Receive Payment: Ensure that the payment for the newly allotted shares is received from the shareholders. Payment can be made in cash, cheque, demand draft, electronic transfer, or any other acceptable mode as specified in the Companies Act, 2013.

File Form PAS-3: Within 30 days of the allotment of shares, file Form PAS-3 with the Registrar of Companies (RoC) to intimate them about the increase of paid-up capital. Attach the necessary documents, including the board resolution for allotment of shares and the list of allottees. Pay the prescribed filing fee.

Update Register of Members: Update the Register of Members maintained by the company to reflect the allotment of shares and the increase of paid-up capital. Ensure compliance with the requirements of Section 88 of the Companies Act, 2013, regarding maintenance of registers.

Update Other Records: Update other relevant records and documents, including the Share Certificate, Register of Members, and any agreements or contracts, to reflect the increase of paid-up capital.
