My new to the family sister in law has stole my families vital information records. She was able to adjust power of attorney to get a hard loan with forged signatures. Our sister-in-law has been living with us for a few months now. We just found out that she's been holding our mail. We noticed she's been asking our mail. I thought she's expecting because she changed her address.
 
There was one mail that didn't make sense, it was my parents house that had a change in power of attorney. Now our three houses are being refinanced by a hard loan with high interest rate with our information. The signatures are fake. Some of the information is wrong on the documents but she was still able to get a hard loan, possibly with a help of a lawyer.



Need help. Not sure what to do.
