Conn. Gen. Stat. § 9-412
Upon the receipt of any page of a petition proposing a candidacy for a municipal office or for member of a town committee, the registrar shall forthwith sign and give to the person submitting the petition a receipt in duplicate, stating the number of pages filed and the date and time of filing and shall forthwith certify on each such page the number of signers on the page who were enrolled on the last-completed enrollment list of such party in the municipality or political subdivision, as the case may be, and shall forthwith file such certified page in person or by mail, as described in section 9-140b, with the clerk of the municipality, together with the registrar's certificate as to the whole number of names on the last-completed enrollment list of such party in such municipality or political subdivision, as the case may be, not later than seven days after receipt of the page. If such page involves a municipal office to be voted upon at a state election, such registrar shall also file a certificate, on a form prescribed by the Secretary of the State, that includes the name and full street address of each candidate and the title and district of such office not later than seven days after receipt of such page. In checking signatures on primary petition pages, the registrar shall reject any name if such name does not appear on the last-completed enrollment list in the municipality or political subdivision, as the case may be. Such rejection shall be indicated by placing a mark in a manner prescribed by the Secretary before the name so rejected. The registrar may place a check mark before each name appearing on the enrollment list to indicate approval but shall place no other mark on the page except as provided in this chapter. The registrar shall not reject any name for which the street address on the petition is different from the street address on the enrollment list, if (1) such person is eligible to vote for the candidate or candidates named in the petition, and (2) the person's date of birth, as shown on the petition page, is the same as the date of birth on the person's registration record. The registrar shall reject any page of a petition which does not contain the certifications provided in section 9-410, or which the registrar determines to have been circulated in violation of any other provision of section 9-410. Petitions filed with the municipal clerk shall be preserved for a period of three years and then may be destroyed.
