I had filled out an application and signed it, but realized I was missing some additional documentation. I have since moved apartments so a lot of the info I gave is wrong. Is there something I can write on a document that means it's no longer valid? I don't own a paper shredder. Would scratching out the signature be sufficient?
To be clear, I ask this question out of curiosity. Also, does the contract exist as soon as the paper has been signed even if the other party hasn't received this, so would this be illegal?
