When signing/transferring over the title deed, aren't all parties involved supposed to be physically present in front of a lawyer/notary? Me thinks due diligence by all members involved in this transaction was severely lacking and they should be held accountable. I.e. Real Estate agent, bank, brokers, what have you. One could even say they all conspired in this property theft. Alternatively, perhaps the victim was lacking some sort of documentation that allowed the illicit procurement to occur?
