Corporations have stockholders not partners. You can purchase 50% of the total shares in the company. You and the company's officers and directors must work out an amount that represents 50% of the value of the company. Once you have paid that amount, the company will issue stock certificates to you as proof of your ownership interest.
This can be a complex transaction and you should consult an attorney to help you.
