You should only use a notary to verify that it is you (and your father) who are signing a contract in front of her/him.  A notary has no legal power or right to give legal advice (unless the notary is a lawyer in this field of law.) What you need is a lawyer to draw up a contract that will be binding and set forth the rights and responsibilities of both you and your father, as well as clarify the status as of the time you sign.  You will also need to amend the corporation's papers to set forth the changes made, usually with the secretary of state's office.  I am able to do this for you because I do business transactions of all kinds.
