Formal complaint means a document filed by a complainant or signed by the Title IX Coordinator alleging sexual harassment against a respondent and requesting that the recipient investigate the allegation of sexual harassment. At the time of filing a formal complaint, a complainant must be participating in or attempting to participate in the education program or activity of the recipient with which the formal complaint is filed. A formal complaint may be filed with the Title IX Coordinator in person, by mail, or by electronic mail, by using the contact information required to be listed for the Title IX Coordinator under 106.8, and by any additional method designated by the recipient. As used in this paragraph, the phrase document filed by a complainant means a document or electronic submission (such as by electronic mail or through an online portal provided for this purpose by the recipient) that contains the complainant's physical or digital signature, or otherwise indicates that the complainant is the person filing the formal complaint. Where the Title IX Coordinator signs a formal complaint, the Title IX Coordinator is not a complainant or otherwise a party under this part or under 106.45, and must comply with the requirements of this part, including 106.45(b)(1)(iii).
