1. The state commissioner of health or person authorized by him shall, upon request, issue to any applicant a certification of any marriage registered under the provisions of this article, unless he is satisfied that the same does not appear to be necessary or required for judicial or other proper purposes.  Any such certification of marriage made by such commissioner or person authorized to act for him shall be prima facie evidence in all courts and places of the facts therein stated.

2. Such certification shall contain a statement of the respective names, dates and places of birth and places of the then residence of each of the parties to such marriage and the date and place thereof.

3. Each applicant for a certification of marriage shall remit to the commissioner with such application a fee of thirty dollars in payment for the search of the files and records and the furnishing of such certification if a record thereof is found or for a certification that a search discloses no record of a marriage.

4. The federal agency in charge of vital statistics may obtain, at a fee acceptable to the commissioner, information from marriage records for use solely as statistical data.
