<prompt> Human: My fiancés parents have used his information to apply for credit cards and loans, without his knowledge, for years. We just found out about it a few months ago after checking his credit score and seeing all the opened accounts that he did not create. We didnt catch it for so long because he never checked his score, since to his knowledge he had no credit cards or loans. Not only have they created all of these account with his name on it, theyre behind on most of the payments and severely damaging his credit because of it. When asked about it, they had thought they could do these things, then pay them off, and he would never know. Their terrible financial decisions kept compounding on each other and now theyre in over their heads, dragging my fiancés credit score down with them. They even put his name on his grandmothers house after she passed in 2012 without his knowledge. We have no idea how to fix all of this its completely shocking and mind-boggling. Any advice would be greatly, greatly appreciated. Side note: My fiancé is named after his father so they have the exact same name minus the number at the end. Which is how I think they managed to maneuver all of this on top of having knowledge of his social security number as most parents do concerning their child.  <response>: Get the SSN changed and file a police report before they do any more damage.Also, you might want to shred your financial documents before ever letting these grifters into your house again. You marry into a family of identity thieves, and theyll eventually start stealing your identity too.
