Loan / Legal question help needed ASAP

Heres what i have,

My uncle took out a loan on my grandmothers house without her permission and he forged her signature on the documents ...he didnt tell anyone about it we only found out after my grandmother tryed to get credit at a store and was declined so we did some research and found that he has taken out a 600k loan on her home and land ...he is not 3 months behind in payments or atleast thats what he says.

My question is what should we do ??? Is the only way to protect her home from being taken to turn this over to the police ??? and Im not sure if that will even help ...are we on the hook for this loan no matter what??? or is there a legal recourse we can take ???

Call the police NOW. This is fraud, forgery, and iam sure a few other things. It is illegal. I would think that she would not be liable for the loan as long as his name is no where on her deeds. If they are then you may have problems.

I agree--that is a crime!
