English: In an idealised Register of Deeds the _point of indefeasibility_ is with the original grant.

To transfer ownership the owner should demonstrate an unbroken chain of deeds with valid transactions from the original grant to the transaction which granted them ownership. We shall call the deeds in this chain _transactional deeds_. By interpreting the _transactional deeds_ the current state of indefeasibility can be interpreted (taking in to account legislation changes, void and other deed errors). Therefore, when analysing _transactional deeds_ indefeasibility is said to be _deferred_. As Torren's was aware _deferred indefeasibility_ can be difficult, time consuming and expensive to calculate. However, corrections can be made against any of the _transactional deeds_. Any errors which exist in _transaction deeds_ can be disputed and, where the dispute is upheld, corrected under the general law of property.

We shall call these errors `transactional errors` (a more general interpretation of the term used in Scotland cite:[DP125(24),reid_midas_2016(9)]).
