Tennessee Code Title 2. Elections § 2-1-107

(a) Any person signing a petition required under this title, whether for nomination of a candidate, for a referendum or for any other purpose, shall include the address of such person's residence. The signer of a petition must include the address of such person's residence as shown on such person's voter registration card in order for that person's signature to be counted; provided, that if the address shown on the petition is within the precinct in which the person is registered but is not the address shown on the registration card, the signature shall be valid and shall be counted. In the event that the signer of a petition includes information on a nominating petition that exceeds the information contained on such person's voter registration card, the signature shall be counted if there is no conflict between them. If no street address is shown on the signer's voter registration card, that person's signature and address as shown on such person's voter registration card shall be sufficient. However, a street address shall be sufficient, and no apartment number shall be required.

(b) Any person who signed a permanent registration card shall sign any petition signed under this title; provided, that any person who printed such person's name on such person's permanent registration card shall print the name on any petition signed under this title. However, failure to comply with the foregoing shall not operate to disqualify any nominating signature or candidate's signature.

(c) A person's regular signature shall be accepted just as such person's legal signature would be accepted. For example, for the purposes of this section “Joe Public” shall be accepted just as “Joseph Q. Public” would be accepted.
