Some unscrupulous scam artist decided to modify a contract that had my signature on it, to make it appear that I had agreed to things I did not. Here is a simplified example:
Bob agrees to pay Fred $20,000 for Fred’s service of building Bob a home.
The bellow signature indicates acceptances into this contract.
Bob’s Signature: Bob
Fred’s Signature: Fred
Now say Bob gets crafty and uses an image editing software, such as Photoshop, to replace "$20,000" with "$10,000".
What would this be called? What word would describe this "falsified" document? I'm not so much looking for a legally correct term, as what's legal is for the judge to decide. I'm looking for an easily understandable term. It looks like I'm going to have to explain this to a few people and I want a way to distinguish between two documents where one had been subtly altered.
Since both signatures are valid, I don’t think it’s correct to say it’s forged. I also considered fake, but not sure this is accurate as (in a sense) it is intended to be different from the original. Other words that come to mind are counterfeit and phony.
