The land registry provides the history of every registered transfer for the parcel, which is the backbone of the trace. If the current owner bought the land from a parent, the deed and the evidence of payment or the declared value at that time matter; if it passed by inheritance, the will, the declaration of transmission and any estate documents show that step. For the holding period, property tax accounts and income tax returns showing farm income demonstrate lawful ownership and use.

For quota, the marketing board's transfer confirmation and payment record replace the deed.
