Legal vs Equitable Interests

Land Law > Legal vs Equitable Interests

The distinction between legal and equitable interests is the foundation of all Land Law analysis. Candidates frequently lose marks by failing to classify interests at the outset or by applying the wrong formality requirements. This distinction determines whether an interest must be registered, can be enforced against a purchaser, and what remedies are available.

What Is Legal vs Equitable Interests in SQE1?

Section 1 of the Law of Property Act 1925 defines legal estates and legal interests exhaustively. Only those interests listed in s.1 can be legal; all others are equitable. A legal interest requires strict compliance with formality requirements (writing, signature, witnesses, or registration). An equitable interest arises in circumstances where the legal requirements are not met but equity will intervene to protect the person's claim.

This classification is not optional—it is the first step in every Land Law analysis. When you encounter a property scenario in the complete guide to Land Law, your first question must always be: is this a legal interest or equitable? Only then can you determine whether it must be registered or whether it can be enforced against a third party. The leading case, Walsh v Lonsdale, illustrates how a contract for a lease may be enforceable in equity even though it lacks the formality required for a legal lease—and this principle underpins the entire framework of legal vs equitable interests in modern Land Law.

Key Principles for SQE1

Section 1 LPA 1925 – Numerus Clausus and Legal Interests: Legal interests are closed-ended. Section 1(2) lists the only legal interests in land: freehold and leasehold estates, mortgages, easements, restrictive covenants, rights of entry, and certain other rights. Any interest not on this list is equitable. This principle (numerus clausus) means you cannot create a new type of legal interest; you must work within the statutory framework.
Formality Requirements for Legal Interests: To create a legal interest, you must comply with strict formality. Writing is required (s.52 LPA 1925) or registration must be completed (Land Registration Act 2002). Without these, even if the parties intend a legal interest, it will fail to be legal and may become equitable. This is critical: formality determines classification.
Equitable Interests – Creation and Protection: Equitable interests arise when legal formality is not met but a court will intervene to protect the person's claim. They may arise from a contract (e.g., Walsh v Lonsdale), a constructive trust, a resulting trust, or an express trust. Equity has power to intervene where conscience is engaged.
Walsh v Lonsdale – Equitable Lease: A contract for a lease, even though not executed as a deed, may be enforced in equity as a lease. The tenant's equitable interest in the land is enforceable against the original landlord and (in certain circumstances) against successors, giving the tenant a remedy if the landlord tries to eject them. This principle—that equity can create proprietary interests—extends beyond leases.
Binding Third Parties – Legal vs Equitable: Legal interests generally bind all third parties. Equitable interests do not automatically bind third parties; they bind all except a bona fide purchaser for value of a legal estate without notice. Under the Land Registration Act 2002, equitable interests may be registered (as minor interests) or may be overriding interests, and will then bind a purchaser.
The Registration Overlay: The Land Registration Act 2002 has modified the old notice doctrine. Under registered land, certain equitable interests must be registered to bind a purchaser; others (such as the rights of a person in actual occupation) override without registration. The distinction between legal and equitable remains important, but registration status is now determinative of priority.

Exam tip

Always classify the interest first: legal or equitable? If legal, has it been created with the necessary formality and registered? If equitable, can it be registered, is it an overriding interest, or is it vulnerable to a purchaser? Do not jump straight to whether an interest binds a purchaser without first classifying it. Many students fail on Land Law questions because they skip this essential first step and try to apply priority rules to an interest they have not properly categorized.

How This Appears in SQE1 Questions

A scenario presents a contract for the sale of land with a note: "The seller has promised the buyer's friend, in writing but not as a deed, that he will grant her an easement over the property after completion." The buyer asks whether the friend's interest is legal or equitable, and whether it binds the buyer if he purchases the property. You must identify that the promise is a contract for an easement, not a legal easement (no deed). It is equitable. If the friend is not registered as having an equitable interest, she will not bind the buyer unless she qualifies as an overriding interest (e.g., she is in actual occupation). This classification framework determines the answer.

This is a classic SQE1 trap.

Common Mistakes Students Make

Confusing legal and equitable formality – Students often treat equitable interests as having no requirements. Equitable interests have different formality requirements (e.g., trusts require writing under s.53 Law of Property Act 1925, though oral trusts of land can arise in certain circumstances).
Forgetting to apply Walsh v Lonsdale – A contract for a lease creates an equitable leasehold interest, enforceable in equity. This principle extends: any contract for a legal interest may create an equitable interest.
Misunderstanding binding effect – Students often assume equitable interests never bind third parties. Under registered land, registered equitable interests and overriding interests bind everyone; it is only unregistered equitable interests lacking actual occupation that are vulnerable to a purchaser.
Mixing formality and registration – These are separate questions. Formality determines whether an interest is legal or equitable; registration determines whether it binds a purchaser. Both must be analysed.

Quick Summary

Section 1 LPA 1925 – legal interests are limited and listed – freehold, leasehold, mortgages, easements, restrictive covenants, and certain others.
Formality is required for legal interests – writing and signature (or deed, or registration) without which the interest may become equitable.
Equitable interests arise where legal formality is not met – but equity intervenes, particularly under trusts and contracts.
Walsh v Lonsdale principle – contracts for legal interests create equitable interests enforceable in equity.
Classification determines priority – you must classify before analysing whether an interest binds a purchaser.
