<prompt> Human: Throwaway account since my main account could be tracked back to me. Not sure if this is a proper sub to post this on but I did also post this to rlegaladvice. Hi PF!Sorry in advance for the long story. Im 26 years old and my mother passed away when I was 17. She was out on a workers compensation claim at the time of her death and her work was found partially liable so my younger sister and I each received a lump sum payment and monthly installments from the years of 2009-2015. I did not know how long the monthly installments were going on for so when I moved out of my grandparents house in 2012 we moved in with them the night my mom passed away in 2009, I hadnt received checks for a few months so assumed they ran out and thought nothing of it at the time. A dumb mistake I unfortunately have to chalk up as a life lessonFast forward to a month ago, I am in the midst of planning my wedding so my fiancé and I were in the process of going over all of our finances so I thought to call the insurance company just to make sure I hadnt missed any checks that were never cashed. They informed me that all checks were cashed and payments stopped in January of 2015. After talking with the original claims adjuster for the account they requested images of the backs of the checks which we just received yesterday. They verified my signature for the old checks and starting in January of 2012 all of the checks were endorsed with two signatures, one of my name and one of my grandmothers name but both in her handwriting and they were stamped being deposited into my grandmothers bank.I contacted the bank and I provided them with the images of all of the checks which they verified all 23 checks each check for the amount 667.01 were deposited into her account. They cannot provide me with much more information since I was not listed on the account. The insurance company is claiming their liability is covered because the payments were made via the plan and the bank is claiming they have no liability because her signature is the only one they need to validate since it is being deposited into her account both signatures are obviously in the same handwriting.Here is the kicker, my grandmother passed away early 2015 and my grandfather passed away early 2016.I filed a police report yesterday but now am hoping for advice if any is available on how I can recoup any of the 15341.23 that was stolen from me. I am in Wisconsin which has a 6 year statute of limitations for fraud if that helps at allThanks in advance for any advice on this and sorry for poor formatting as I am posting this on mobile.  <response>: I would think the bank would be liable at least to some extent. The whole point of signature cards is so this doesnt happen.Definitely talk to an attorney.
