Lots of room for debate as to facts or missing facts..as posted the EX did get it refinanced...at least for a while Reads as if EX has rather unclean hands ..while impossibility to perform is often a good defense ..Im not so sure its a good on with dirty hands and the fact that you did seem to perform and then dropped the ball again.

If Dads wants to bail out daughter to refinance you might be smart to focus on same and not the unknown forger.
