Question: 'Adverse possession is a relic of a pre-registration era and serves no defensible purpose in the modern law of registered title.' Discuss.
---
Introduction
Adverse possession permits a squatter to acquire title after continuous possession for a prescribed period. Historically rooted in limitation of actions and the relativity of title, the doctrine has survived the transition to comprehensive registration but has been fundamentally reconfigured by the Land Registration Act 2002. This essay argues that while the traditional justifications for adverse possession have weakened, the doctrine retains residual curative and structural functions which explain—though may not fully justify—its persistence.
I. Traditional rationales and their erosion
The conventional justifications include: (1) evidential concerns (stale claims are hard to defend); (2) punishment for neglect (vigilantibus non dormientibus); (3) certainty (settling expectations); (4) efficient land use (rewarding productive occupiers); and (5) administrative necessity (curing boundary discrepancies).
In the context of unregistered land, these rationales have force. Without a comprehensive register, possession serves as prima facie evidence of title; long lapse of time undermines the reliability of documentary proof. The Limitation Act 1980 reflects this: twelve years' adverse possession extinguishes the paper owner's title, and the squatter's possessory title fills the vacuum (Pye v Graham [2002] UKHL 30).
However, the advent of registered title undermines several of these justifications. The Land Register provides a conclusive record of title (LRA 2002, s 58); possession is no longer necessary to prove ownership. Boundary plans, filed at HM Land Registry, reduce (though do not eliminate) boundary disputes. The Law Commission (Law Com No 271, para 14.5) concluded that 'the protection of property rights is a fundamental principle' and that registered proprietors should not lose title merely through lapse of time.
Yet the Law Commission did not abolish adverse possession. Why?
II. The curative functions of adverse possession under the LRA 2002
Schedule 6 LRA 2002 preserves adverse possession in three exceptional cases (para 5):
- Estoppel (para 5(2)): Where it would be unconscionable to deny the squatter registration (Zarb v Parry [2011] EWCA Civ 1306). This addresses cases of detrimental reliance and informal assurances.
- Entitlement for another reason (para 5(3)): For example, the squatter is entitled under a will or contract but has not been registered. Adverse possession here is a backstop remedying registration failures.
- Boundary disputes (para 5(4)): Where the squatter has reasonably believed adjacent land to be theirs for ten years (Best v Chief Land Registrar [2015] EWCA Civ 17). This addresses the practical reality that boundary plans are often not definitive (LRA 2002, s 60 provides that boundaries are 'general' unless determined).
These exceptions show that adverse possession serves curative, not punitive, functions in registered land. It remedies:
- Gaps between informal property arrangements and formal registration;
- Boundary uncertainties arising from the general boundaries rule;
- Estoppel claims that ought in conscience to be recognised.
Without these exceptions, the register might become a trap: rigid formalism would defeat reasonable expectations and reliance.
III. The structural role of possession
Professor Ben McFarlane defends adverse possession on structural grounds. The common law recognises possession as an autonomous property interest; the squatter acquires a fee simple estate from the moment of taking possession, good against all the world except those with better title. This reflects the doctrine of relativity of title: ownership is not absolute but relative.
Adverse possession thus reinforces this foundational principle. If possession were irrelevant after registration, the law would move towards a civilian model of absolute ownership, divorced from physical control. McFarlane argues this would be a mistake: possession generates use-rights which ought, over time, to ripen into ownership, especially where the paper owner has neglected the land.
Furthermore, the LRA 2002 preserves a role for possession through Schedule 3, paragraph 2: the interest of a person in actual occupation is an overriding interest. If possession matters for third-party rights, why not for acquisition of title?
IV. Human rights and proportionality
Critics, including the dissenting judges in Pye v United Kingdom (2008) 46 EHRR 45, argue that adverse possession effects a deprivation of property without compensation, violating Article 1 Protocol 1 ECHR. The Grand Chamber (10–7) upheld the doctrine, citing the wide margin of appreciation afforded to states in regulating property and the public interest in certainty of title.
Yet the narrow majority and powerful dissent reveal normative fragility. The LRA 2002 reforms can be seen as a partial response: the notice-and-objection procedure provides procedural protections, and the restriction of adverse possession to exceptional cases mitigates the risk of arbitrary deprivation. In this sense, the LRA 2002 recalibrates adverse possession to comply with human rights standards without abolishing it.
V. Comparative perspectives
New Zealand abolished adverse possession for registered land except in cases of genuine mistake (Land Transfer Act 2017, s 81A). This reflects the view that in a Torrens system, indefeasibility trumps possession. England could follow suit, retaining only the boundary exception.
Yet this would eliminate the estoppel and 'entitlement for another reason' exceptions, potentially producing harsh results where informal arrangements have been relied upon.
Conclusion
Adverse possession in its traditional, automatic form (as under the Limitation Act 1980) may indeed be a 'relic'. But the LRA 2002 has transformed the doctrine into a limited, curative mechanism addressing boundary disputes, estoppels, and registration failures. Far from serving 'no defensible purpose', Sch 6 performs essential functions in a system of registered title that retains general boundaries and recognises the normative significance of possession. The real question is not whether adverse possession should exist, but whether its current formulation strikes the right balance. The narrow exceptions in para 5, the two-year grace period, and the notice procedure suggest that the LRA 2002 has achieved a workable, if imperfect, compromise.
