It would be the crime of Fraud at the very least and possibly Larceny.
The quit claim deed would be invalid if you can prove what you have stated here to me. Also you will need to be able to prove your statements to sustain a fraud or laceny conviction.
The quit claim deed is the "real deed" until you can prove that it is not the real deed designed to properly transfer the property. In order for property to be validy transfered it must be deeded to the new owner but then that new deed should be registered so the others are aware of who is in fact the true owner.
