If a company is “limited by shares”, it means that it is owned by shareholders who have a say in what happens to the company. If changes are to be made, they need to be informed. If the company has normal shares this means that the directors get a vote on the company decisions as well as receiving dividend payments.
If a company is limited by shares, then there needs to be at least one shareholder, but there’s no maximum limit. If there is only one, then they will own all of the company. A share can be any amount, but shareholders must realise they will have to pay the full amount of their shares if the company folds.
During registration, you’re required to provide information about the shares (known as “statement of capital”). The number of shares and their value as well as the names and addresses of all the shareholders, which are known as “members”.
