Can a notary notarize a document in which his or her employer has an interest?

Yes. In fact, there are statutes that specifically permit such notarizations. For example, §121.002 of the Texas Civil Practice and Remedies Code authorizes an employee of a corporation to take an acknowledgment of a written instrument in which the corporation has an interest. In addition, §199.002 of the Texas Finance Code specifies that a notary public is not disqualified from performing a notarization of a document, solely because of the notary public’s ownership of stock or participation in or employment by a state trust company that has an interest in the underlying transaction.
