Hate to tell you but 99% of lawyers will not take family squabbles in a probate case on a contingent fee. This is most likely some family member that is target of such allegations, and forgery cases are very difficult to blame on the banks as opposed to the criminal doing the forging. If this is something the estate needs to pursue, then the estate will likely have to hire a lawyer at some out of pocket expense to pursue such claims.
