Limited liability is a legal status in which a person's financial liability is limited to a fixed sum, most commonly the value of a person's investment in a corporation, company, or joint venture. If a company that provides limited liability to its investors is sued, then the claimants are generally entitled to collect only against the assets of the company, not the assets of its shareholders or other investors. A shareholder in a corporation or limited liability company is not personally liable for any of the debts of the company, other than for the amount already invested in the company and for any unpaid amount on the shares in the company, if any—except under special and rare circumstances that permit "piercing the corporate veil." The same is true for the members of a limited liability partnership and the limited partners in a limited partnership. By contrast, sole proprietors and partners in general partnerships are each liable for all the debts of the business (unlimited liability).
Although a shareholder's liability for the company's actions is limited, the shareholders may still be liable for their own acts. For example, the directors of small companies (who are frequently also shareholders) are often required to give personal guarantees of the company's debts to those lending to the company. They will then be liable for those debts that the company cannot pay, although the other shareholders will not be so liable. This is known as co-signing. A shareholder who is also an employee of the corporation may be personally liable for actions the employee takes in that capacity on behalf of the corporation, in particular torts committed within the scope of employment.
