Conn. Gen. Stat. § 7-23: Records and copies.

Town clerks shall keep the records of their respective towns and truly enter therein, either by transcribing or by photographic, micrographic, electronic imaging or any other process approved by the Public Records Administrator, all votes of the town and give true copies of the same and of all deeds and other instruments by them recorded; and all attested copies of deeds, with a certificate of the town clerk or assistant town clerk that they have been recorded, shall be conclusive evidence of that fact. No copy of record certified by the town clerk or assistant town clerk of any town shall be deemed valid in law unless the seal of such town is affixed thereto; and the town clerk of each town or his legally qualified assistant shall affix the seal of such town to all certified copies of record, and no fee shall be allowed for affixing the same.
