Transfer of shares is now done internally within the company. Then the company gets it in the company records at CAC, through filing an application for Surrender of Shares and then Reallotment of shares.
Surrender of Shares, is when a shareholder that decides to leave the company surrenders his or her shares back to the company. The company will then Reallot the shares to existing shareholders
For increase in share capital, when a share capital is increased either to meet up industry standards or when the company has new share holders or probably for other business purposes.
For instance, you have 100k share capital you may want to increase to one million probably because you want to apply for a contract or add more objects and one of the objects is a regulated object, that must automatically lead to the increase.
For example a hotel decides to run a travel and tour the share capital must increase to 30m. Or a company decides to add sport betting, Nigerian Lottery demands any betting company must have 30m share capital.
Another thing you should know, the board of a company is made up of the directors and shareholders. The shareholders are owners or subscribers to the share capital. The shares allotted to them is their stake in the company.
Also board resolution is filed internally
