Persona "A" has a document hand written by deceased individual to person "B" and copied to "A".
"B" denies the document and its contents and accuses "A" of fabricating it.
How can "A" make the sure the document is admissible as evidence?
Can "A" use the following methods to help make the document admissible as evidence:
1. The decease person had discussed the contents of his letter with "C". "C" is willing to testify to this in court.
2. Also based on "C's long association with the deceased person, can provide original handwriting samples of deceased person for comparison purposes.
Any other suggestions?
