Comparatio Literarum Law and Legal Definition

Comparatio literarum is a Latin term. It means ‘comparison of writings.’ In Roman law, the term is used to refer to the act of comparing writings in order to determine authorship.

In Scotland, this one of the means resorted to for proving the truth or falsehood of a forgery allegation. However, when a comparatio literarum is resorted to in order to prove that a particular writing has been written by the accused, it is considered as a much more doubtful species of evidence.
