C.R.S. § 1-13.5-614

When all the votes have been read and counted, an election judge shall deliver to the designated election official the certificate and statement required by section 1-13.5-613 , the ballot boxes and all keys or seals thereto, and the registration and property owners lists, pollbooks, tally sheets, spoiled ballots, unused ballots, ballot stubs, oaths, affidavits, and other election papers and supplies. The delivery must be made at once and with all convenient speed, and informality in delivery does not invalidate the vote of any polling place when delivery has been made prior to the completion of the official abstract of the votes by the canvassers pursuant to section 1-13.5-1305 . The designated election official shall provide a receipt for all papers so delivered.
