A characteristic common to partnership and sole proprietorship is

The characteristic that is common to partnership and sole proprietorship is "unlimited liability". Unlimited liability refers to the owner(s) being personally liable for all the debts and obligations of the business. This means that in the event of financial losses or debts incurred by the business, the personal assets of the owner(s) can be used to settle those obligations. In a sole proprietorship, there is only one owner who has unlimited liability. In a partnership, all the partners share unlimited liability. This is in contrast to corporations, where the liability of shareholders is limited to the amount of their investment.
