§ 1415 Handwriting Authentication Evidence

• •If someone writes something, you can prove it's really theirs by checking their handwriting.
• •This is about making sure a note or letter is truly from the person who signed it.
• •Experts or people who know the person's handwriting can help prove it's real.

Your friend writes you a note saying they'll pay you back $50, but later says they didn't write it.

You can show the note to someone who knows your friend's handwriting (like their teacher) to prove they really wrote it.
