First of all, the only time you MUST redisclose is when you lock the rate. Every other time is at your discretion, usually to capture a fee.
Second, when did you find out there was a judgment against the seller and you were going to require lenders' ti? If it was more than three (3) days ago, you cannot redisclose.
Third, you are requiring a new fee as a condition of getting the loan so yes, I would definitely redisclose. The fact that the company is not on your list doesn't affect what should be on the GFE and will only come into play on the HUD.
