After you file

The answer is still not clear.

I'm getting the impression that one the payment plan  agreement  is mailed, that's it you do not  get another  copy. 

The only way I've  been able to get a printed agreement was to revise  my current  agreement.

This is similar to a contract with my landlord.

  It's my responsibility to keep and preserve it. 

 No copies are available  and it's my word against his.
