Based on the posts in this thread, it seems that ALJ's need to be asking everyone if they have an unsigned contract for payment for work sitting on the desk at home waiting for the outcome of the disability hearing.

I think withholding pertinent information is also committing fraud.

Everyone here is speculating about how this will be treated by SSA. I don't think it is possible to know it advance. Using all your creative juices in a marathon writing session in a month may or may not mean that you can do that every day from then on. Obviously you didn't do it before that one session. There are plenty of one-hit wonders out there.

I think the ALJ should be told. You will have to report it at some point since there will be a paper trail and if someone decides to look back at your ALJ decision, it could be discovered that you were less than credible.

If you have an attorney, you should take his or her advice, since he or she knows the totality of your case.
