DEFINITION of 'Ultra Vires Acts'

Any act that lies beyond the authority of a corporation to perform. Ultra Vires acts fall outside the powers that are specifically listed in a corporate charter or state law. They can also be any action that is specifically prohibited by the corporate charter.

BREAKING DOWN 'Ultra Vires Acts'

Ultra Vires acts can also be defined as any excessive use of corporate power that has been granted. These acts cannot be legally defended in court. They will, in fact, leave the corporation vulnerable to lawsuits by employees or other parties.
