My dh took out a life insurance policy about a year ago, his sister signed to say she'd witnessed his signiture on the documents. However now she is saying she didn't witness his signiture and wants us to somehow get all the documents back so she can resign and watch him sign again. I can't for the life of me remember. But what I'm concerned about is she is saying if my dh should die she'd have to confess to not witnessing the signiture and that I'd lose alot of money.What should I do?
