Comparison: The 10-Year Rule vs The 12-Year Rule
The legal framework governing adverse possession splits sharply depending on the date and registration status of the land:
The 10-Year Registered Land Procedure (LRA 2002):
• Requires 10 years continuous possession.
• Does NOT automatically confer title; requires Form ADV1.
• Land Registry serves notice on the registered owner.
• Defeated by counter-notice unless a Schedule 6 exception applies.
The 12-Year Unregistered Land Procedure (Limitation Act 1980):
• Requires 12 years continuous possession.
• Section 17 automatically extinguishes the true owner's legal title upon expiry of year 12.
• Requires Form FR1 (First Registration) and Form ST1.
• The former paper owner cannot defeat the claim simply by objecting.

Tacking Periods of Successive Squatters
Under the doctrine of successive squatters (confirmed in Mount Carmel Investments Ltd v Peter Thurlow Ltd [1988]), an adverse possessor can pass their inchoate possessory title to a purchaser.
To rely on tacking: (1) There must be no gap in possession, (2) The predecessor must execute a formal Statement of Truth (Form ST1) or statutory declaration verifying their dates of occupation, and (3) A formal deed of assignment of possessory rights should accompany the conveyancing transfer.
