If you have decided to take the lump sum payment, be sure to check the website to make sure your documents show "complete".
I sent docs in October 7, called three times to confirm receipt and I was told they had been received and uploaded. Just happened to visit website November 21, only to see spousal waiver form said "incomplete".
Called first thing Monday only to be told, the Notary failed to put my spouse's name in at the bottom of the form. Asked them why wasn't I called, rep said they don't have to. It is employee's responsibility to make sure docs are correct. Asked how come when I called no one said anything,rep said error was overlooked. Had to overnight corrected doc to ensure you receive lump sum payment. If I had NOT went on website, never would have known doc was not complete and then I would not have received my lump sum and would have been wondering why.
