§57-2-1. Handwriting analysis.
In any civil or criminal action or proceeding, any writing
proved to the satisfaction of the judge of a court of record in an
in-camera hearing to be in the handwriting of the person who is
alleged to have written it, whether or not made in the ordinary
course of business, may, if the court further finds that its
probative value outweighs its prejudicial effect, be admitted into
evidence for the purpose of making a comparison with a disputed
writing on the issue of whether or not the disputed writing is
genuine. The authenticity of each writing shall be finally
determined by the trier of fact.
