§ 1400 Writing Authentication Rules

• •Authentication means proving a document is real and not fake.
• •You need enough evidence to show the document is what you say it is.
• •There are different ways to prove a document is real, not just one way.

You sign a contract to buy a house, but someone says your signature is fake.

You have to show proof, like a witness or an expert, to confirm that the signature is really yours. This is called authenticating the document.
