Hello what are the consequences of being a director of a company which you are not the owner

I assume that the "company" to which you refer is a corporation.  Many corporations, particularly publicly traded corporations, have outside directors who are neither employed by nor substantial shareholders of the corporation.  Outside directors are usually compensated by the corporation, but they take on certain obligations.  Directors have fiduciary duties to the corporation and, in some circumstances, to its creditors.  They also have obligations to investors and potential investors.  If any of these people feels that the director has breached his/her obligations, the director can be sued (although the corporation often has insurance which can cover the attorneys' fees incurred in defending such a suit and, depending on the basis for liability, an award against the director.)
