I don't know the law on this, but recently I had a signing service email me that they would not be paying my fee as I did not follow instructions. I was not told at hiring that they needed faxbacks. They gave me a client that delayed his signing for 3 days. If it was now a rush, they should have informed me that it was urgent to receive the faxed docs. Cohesion Signing Service is not so Cohesive!
