“I, ...., (insert name of elector) an elector of the town of .... (insert name of town) now registered at .... (insert name of street, and number, if any) do hereby state under oath that I maintain a place of abode at .... (insert name of street, and number, if any) within such town; that my absence is temporary from said town for the following reasons: ....; that it is my present intention to maintain a domicile and residence in said town and return thereto whenever the necessity for temporary absence has ceased; that I am not now registered elsewhere as an elector nor have I any present intention so to register.

Notary Public or other officer empowered to administer oaths”.
Upon receipt of such application, if either registrar, in writing signed by him, certifies on such application that he believes such claim of residence has sufficient foundation in fact, the name of such elector shall be retained on the active registry list of the municipality and his right to vote therein at the next succeeding regular election or primary shall not be challenged by the registrars because of any question of residence. Otherwise, the name of such elector shall be placed on the inactive registry list for four years and then removed from the registry list. All applications herein provided for shall be kept by the registrars as a permanent record; and, when no application for retention of his electoral privilege is received from any elector whose right to have his name retained on the registry list is challenged under the provisions of this section, the registrars shall keep as a permanent record evidence that the notice required by this section has been sent in the manner provided herein.
