The land register is the backbone of immovable-property law, yet the register does not always reflect the true legal position. Actions for cancellation and registration founded on defective registration, collusion to defeat heirs (muris muvazaası), forgery, incapacity or lesion require particular care as to proof and limitation.
The office unifies the title record, instruments, witnesses and expert evidence in a single narrative, and establishes before the court the defect in registration and the true right-holder.
