Prescription is the law's recognition that long, peaceable and unchallenged enjoyment of a right over another's land ought, after a fixed span of years, to ripen into a legal entitlement. Under Section 15 of the Indian Easements Act, 1882, a right of way, a right to light and air, a right of support, a watercourse and similar easements become absolute and indefeasible when they have been enjoyed peaceably, openly, as of right and without interruption for twenty years — thirty years where the servient land belongs to the Government. But the statute is exacting: each of the conditions is a separate hurdle, the burden lies wholly on the claimant, and the period must end within two years next before the suit. This article unpacks every condition, the rights expressly excluded by Section 17, and the leading decisions — from Sultan Ahmad v. Valiullah to the Supreme Court's 2024 ruling in Manisha Mahendra Gala v. Shalini Bhagwan Avatramani — that judiciary and CLAT-PG aspirants must command.

What Prescription Means and Where It Sits in the Act

Prescription, in the law of easements, is one of the four recognised modes by which an easementary right may be acquired, the others being express or implied grant, easement of necessity and customary easement. Where the others rest on a grant (real or presumed) or on absolute necessity, prescription rests on a different idea altogether: the lapse of a defined period of open enjoyment, which the law treats as conclusive of a right even though no grant can be proved. The doctrine reflects the policy that long-acquiesced-in user should not be disturbed, and that an owner who sleeps on his right to object for two decades cannot later complain.

The acquisition of easements by prescription is governed by Section 15 of the Indian Easements Act, 1882, and the rights so acquired are styled prescriptive rights. A near-identical provision appears in Section 25 of the Limitation Act, 1963, which applies in territories where the Easements Act has not been extended; the two are read together, and the substantive conditions are the same. As the Supreme Court reiterated in Manisha Mahendra Gala v. Shalini Bhagwan Avatramani (2024 INSC 293), a claimant invoking prescription must establish each statutory ingredient by cogent evidence — the right is not presumed in his favour. For the foundational vocabulary of dominant and servient heritage on which this whole scheme rests, see our note on the essentials of an easement.

The Statutory Framework: Section 15 Dissected

Section 15 provides that where the access and use of light or air to and for any building have been peaceably enjoyed therewith, as an easement, without interruption, and for twenty years; and where support from one person's land has been peaceably received by another person's land subjected to artificial pressure, as an easement, without interruption, for twenty years; and where a right of way or any other easement has been peaceably and openly enjoyed by any person claiming title thereto, as an easement, and as of right, without interruption, for twenty years — the right to such access, support or other easement shall be absolute.

Three structural points emerge. First, the section enumerates three broad categories: light and air, support, and the residual class of "right of way or any other easement." Second, the qualifying adverbs differ subtly between the categories — for ways and other easements the user must be "peaceably and openly" and "as of right," carrying the full common-law triad discussed below, whereas for light and air the phrase "as of right" is conspicuously absent because access of light is a negative easement that does not depend on a claim of right against the servient owner. Third, the closing limb of the section commands that each twenty-year period "shall be taken to be a period ending within two years next before the institution of the suit" in which the claim is contested. This last requirement is frequently fatal to otherwise sound claims and is examined separately below.

Condition 1 — The Right Must Be Definite and Certain

The first requirement is that the right claimed be precise in its content and extent. A vague, indefinite or fluctuating user cannot ripen into an easement, because the servient owner must have known, throughout the prescriptive period, the exact nature and measure of the burden being imposed on his land. A claimed right of way must relate to a defined track; a claimed right of light must relate to specified apertures; a claimed watercourse must follow a defined channel. The reason is evidentiary as much as conceptual: prescription presumes a grant from long enjoyment, and a grant must have a certain subject-matter.

This is why Section 17 (discussed later) bars prescription of a right to surface-water "not flowing in a stream and not permanently collected in a pool, tank or otherwise," and of underground water "not passing in a defined channel" — such user is inherently uncertain and incapable of supporting a defined easement. The certainty requirement also explains the judicial insistence, restated in Manisha Mahendra Gala, that the claimant identify with precision the locus and dimensions of the way or right asserted; a litigant who pleads a generalised liberty to cross "somewhere" over the servient land will fail at the threshold.

Condition 2 — Enjoyment 'As of Right': Nec Vi, Nec Clam, Nec Precario

The most heavily litigated condition is that the enjoyment be "as of right." English and Indian law alike capture its content in the Latin maxim nec vi, nec clam, nec precario — not by force, not by stealth, and not by permission. Each limb is independently essential.

Nec vi (not by force): the user must be peaceable. Enjoyment maintained against the servient owner's active resistance, or by violence, or in defiance of his protests and obstructions, is not peaceable and cannot found a prescriptive right. A user that the owner has continuously contested is, by definition, not acquiesced in. Nec clam (not by stealth): the user must be open and notorious, such that the servient owner, with reasonable diligence, would know of it. Enjoyment carried on secretly — for instance an underground drain concealed from the owner — cannot mature into an easement, for the law will not presume acquiescence in a burden the owner never had the means to discover. Nec precario (not by permission): the user must not rest on the licence or consent of the servient owner.

The third limb is decisive in Indian litigation. As the Supreme Court emphasised in Bachhaj Nahar v. Nilima Mandal, (2008) 17 SCC 491 (AIR 2009 SC 1103), the right must be enjoyed independent of any agreement with the owner of the servient land; "any user with the express permission of the owner will be a licence and not an easement." Permissive enjoyment, however long, cannot ripen into prescription — it is referable to consent, not to right. On the distinction between a revocable licence and an easement, our note on the key definitions in the Act is a useful companion.

Condition 3 — Peaceable, Open and Independent Enjoyment

Closely allied to the "as of right" requirement is the insistence that the enjoyment be both peaceable and open, and that it be independent — that is, exercised in the claimant's own right and not derived from some other title. An important corollary, drawn out in Bachhaj Nahar, is that the user must be enjoyed by a person "claiming title thereto, as an easement": the claimant must assert the user as an easement over land he acknowledges to belong to another, not as an incident of his own ownership.

This distinguishes prescription from adverse possession, with which it is sometimes confused. In adverse possession the trespasser denies the owner's title and asserts ownership in himself; in prescription the dominant owner concedes the servient owner's title and claims only a limited right of user over that land. The Supreme Court's treatment of settled and adverse possession in Rame Gowda v. M. Varadappa Naidu, AIR 2004 SC 4609 ((2004) 1 SCC 769), underlines that the two doctrines protect different interests and require different proof; a claimant must be clear which he is asserting. Where the user is in truth permissive, or is referable to co-ownership or to a tenancy, it is not "independent" and the prescriptive clock never starts.

Condition 4 — Continuous Enjoyment Without Interruption

The fourth condition is that the enjoyment continue, without interruption, for the full statutory period. "Interruption" here is a term of art and does not mean every break in actual user. Under the scheme of Section 15, an interruption that defeats the claim is the obstruction of the enjoyment by some person other than the claimant, which the claimant has submitted to or acquiesced in. Crucially, the obstruction must have been acquiesced in for a continuous period; a temporary obstruction that the dominant owner does not accept, but contests, does not break the prescriptive continuity.

This is reinforced by the rule, drawn from the analogous English provisions, that nothing is to be deemed an interruption unless it has been submitted to or acquiesced in for one year after the claimant had notice of it and of the person making or authorising it. The practical effect is generous to the dominant owner: a brief blocking of the way, promptly objected to, neither resets nor defeats the prescription. But a sustained obstruction, met with submission, will. The Supreme Court in Manisha Mahendra Gala dismissed the claim precisely because the appellants could not establish continuous and uninterrupted user of the disputed road for twenty years — gaps and the absence of cogent proof of unbroken enjoyment were fatal. The lesson for advocates is evidential: oral assertion is rarely enough; documentary and disinterested testimony of unbroken user across two decades is what carries the burden.

The Period: Twenty Years, Thirty for Government Land

The prescriptive period is twenty years for private servient land. Where, however, "the property over which a right is claimed under this section belongs to Government," Section 15 directs that for the words "twenty years" the words "thirty years" be substituted. This longer period reflects the policy of protecting public and Government property from the slow erosion of private prescriptive claims, and mirrors the extended limitation periods the law generally accords to the State.

The period must, of course, be continuous and must satisfy all four conditions throughout. A user that was permissive for the first ten years and only later became hostile does not aggregate the permissive years; time runs only from the point at which all the statutory characteristics are simultaneously present. Equally, a user interrupted (in the technical sense) part-way through must begin afresh thereafter. Aspirants should note that the twenty/thirty-year period under the Easements Act is distinct from, though closely modelled on, the period in Section 25 of the Limitation Act, 1963, which adopts the identical figures.

The Two-Year Rule: Period Ending Before the Suit

One of the most commonly overlooked requirements lies in the final paragraph of Section 15: each twenty-year (or thirty-year) period "shall be taken to be a period ending within two years next before the institution of the suit wherein the claim to which such period relates is contested." The consequence is that a prescriptive easement is not perfected merely by completing twenty years of qualifying user; the right becomes "absolute" only when, and is established only if, the qualifying period ends within the two years immediately preceding the contesting suit.

Two propositions follow. First, the suit must be filed after the right has been perfected by twenty years' user. Second, the suit must be filed within two years of the cause of action — typically the obstruction or denial that prompts the litigation. If the obstruction occurred, and the claimant slept on it for more than two years before suing, the period of enjoyment relied upon no longer "ends within two years next before the suit," and the claim fails however long the prior enjoyment. This explains the celebrated dictum in Sultan Ahmad v. Valiullah, (1912) 10 ALJ 227, that the combined effect of the Easements Act and the Limitation Act is that a prescriptive easement is, until then, an inchoate right — it cannot be said to be perfected until it is established by the decree of a competent court. Mere completion of twenty years confers a right capable of being perfected; only suit and decree within the prescribed window perfect it.

Rights That Cannot Be Acquired by Prescription — Section 17

Section 17 carves out four categories of right which, by their very nature, cannot be acquired by prescription, however long enjoyed:

(a) a right which would tend to the total destruction of the subject of the right, or of the property on which liability would be imposed if the acquisition were made; (b) a right to the free passage of light or air to an open space of ground (as distinct from a building, for which Section 15 expressly permits prescription); (c) a right to surface-water not flowing in a stream and not permanently collected in a pool, tank or otherwise; and (d) a right to underground water not passing in a defined channel.

The rationale is coherent. Clause (a) protects against rights that would annihilate the servient subject-matter, which the law will not allow to vest by mere lapse of time. Clauses (c) and (d) reflect the certainty principle: diffuse surface-water and percolating underground water are too indefinite to support a defined easement, dovetailing with Condition 1 above. Clause (b) draws the vital distinction between light or air to a building — which is prescriptible under Section 15 — and light or air to open ground, which is not, because access of light to open land is a natural advantage shared by all and not a defined easement attached to apertures in a structure. The contours of these excluded categories are best appreciated alongside the broader taxonomy in our note on the kinds of easements.

Prescriptive Right to Light and Air: The Special Position

The prescriptive right to light and air to a building deserves separate treatment because it is a negative easement — it does not entitle the dominant owner to do anything on the servient land, but rather to prevent the servient owner from obstructing the light that has long reached the dominant owner's windows. Section 15 permits its acquisition over twenty years of peaceable, uninterrupted enjoyment, and notably omits the words "as of right" for this category, since the enjoyment of light is not adverse to the servient owner in the way a right of way is.

Acquisition, however, is only half the story. The measure of the right and the threshold for actionable obstruction were settled by the House of Lords in Colls v. Home and Colonial Stores Ltd, [1904] AC 179, which Indian courts have consistently followed. Twenty years' enjoyment does not confer an absolute right to all the light previously received; rather, the dominant owner is entitled only to so much light as is required for the ordinary, comfortable and beneficial use of the premises "according to the ordinary notions of mankind." An obstruction is actionable only if it amounts to a nuisance — a substantial privation of light enough to render the premises uncomfortable for residence, or (for business premises) materially less fit for the business carried on. A mere diminution of light, leaving sufficient for comfortable use, is not actionable. This nuisance-based standard is the touchstone Indian courts apply when a neighbour's new construction is alleged to infringe an acquired right to light.

Exclusion in Favour of the Reversioner — Section 16

Section 15 must be read with Section 16, which protects a reversioner of the servient heritage. Where the servient land has, during the prescriptive period, been held under an interest for life or for a term of years exceeding three years, the time of enjoyment during the continuance of that limited interest is excluded from the computation of the twenty years — provided the person entitled on the determination of that interest resists the claim within three years next after it determines.

The logic is fairness to the absent reversioner. A limited owner — a life-tenant or a lessee — may have acquiesced in a user that the reversioner had no power to prevent and no occasion to know of. It would be unjust to allow an easement to be fastened on the reversioner's land through the inaction of a life-tenant. The statutory illustration makes this concrete: A sues for a declaration of a right of way over B's land and proves twenty-five years' enjoyment; but B shows that for ten of those years C held a life-interest, that B became entitled on C's death, and that B contested A's claim within the permitted period after C's death. The ten years of C's life-interest are excluded, leaving A short of the statutory twenty. Section 16 thus operates as a significant qualification on the apparent simplicity of "twenty years' enjoyment."

Burden of Proof and Pleadings

Prescription is, in Indian practice, the most difficult of the modes of acquisition to establish, precisely because the entire burden rests on the claimant and each ingredient must be separately proved. Unlike English law, which more readily presumes "as of right" user from long enjoyment, Indian courts require the claimant affirmatively to plead and prove that the user was peaceable, open, as of right, independent and uninterrupted for the full statutory span ending within two years of suit.

The Supreme Court in Bachhaj Nahar v. Nilima Mandal, (2008) 17 SCC 491, laid down with precision what a prescriptive claim must contain. The pleadings for an easement by prescription differ from those for an easement of necessity or by grant; a dominant owner seeking declaratory or injunctive relief must plead and prove the nature of the easement, the manner of its acquisition (here, the twenty-year user with all its qualities), and the manner of disturbance or obstruction. A court cannot grant relief on a case of prescription that was never pleaded, nor convert a claim of grant into one of prescription at the appellate stage. This is a recurring trap in litigation and a favourite of examiners. The contrasting and lighter proof of easements of necessity and quasi-necessity is worth studying side by side, as is the related concept covered in our note on quasi-easements.

Prescription Distinguished from Grant, Necessity and Custom

It assists examination answers to place prescription against its siblings. An easement by grant arises from the act of parties — an express or implied conveyance — and, as the Supreme Court held in Hero Vinoth (Minor) v. Seshammal, AIR 2006 SC 2234, an easement by grant does not get extinguished merely because an alternative access becomes available; its source is the grant, not necessity. An easement of necessity under Section 13 arises where the dominant owner cannot use his property at all without it, and dies the moment the necessity ends (Section 41). A customary easement under Section 18 rests on a local usage of immemorial standing and requires no dominant heritage at all.

Prescription stands apart from each: it rests neither on a proven grant, nor on absolute necessity, nor on local custom, but solely on the legal effect the statute attaches to twenty years of qualifying enjoyment. Its closest analogue is the lost-grant theory of English law — the fiction that such long enjoyment must have originated in a grant since lost — but the Indian Act dispenses with the fiction and supplies a statutory rule instead. For the full landscape of how these modes interrelate, return to the Indian Easements Act notes hub.

A Practical Checklist for a Prescriptive Claim

Drawing the threads together, a claimant asserting a prescriptive easement must establish, cumulatively: (1) a definite and certain right of a kind capable of being an easement and not barred by Section 17; (2) enjoyment as of rightnec vi, nec clam, nec precario — that is, peaceable, open and not permissive; (3) enjoyment independent of any agreement, asserted as an easement over land conceded to belong to another; (4) continuous enjoyment without interruption in the technical sense, for the full period; (5) a period of twenty years (thirty for Government land) ending within two years next before the contesting suit; and (6) where Section 16 is engaged, allowance for the exclusion of any life or long-term interest in the servient land.

The failure to satisfy any single condition is fatal, and the modern authorities — culminating in Manisha Mahendra Gala v. Shalini Bhagwan Avatramani (2024 INSC 293) — show the courts insisting on rigorous, particularised proof rather than loose assertions of "long use." For students, the discipline is to memorise the six conditions as a sequence and to attach to each the controlling authority: certainty and Section 17; "as of right" and Bachhaj Nahar; the two-year rule and the inchoate-right principle of Sultan Ahmad v. Valiullah; the measure of the light easement and Colls; and continuous user and Manisha Mahendra Gala. A grounding in the introduction to easements ties this technical scheme back to first principles.

Frequently asked questions

What is the prescriptive period for acquiring an easement under the Indian Easements Act?

Twenty years of peaceable, open, as-of-right and uninterrupted enjoyment under Section 15. Where the servient property belongs to the Government, the period is thirty years. The period must also end within two years next before the suit in which the claim is contested.

What does 'nec vi, nec clam, nec precario' mean in the context of prescription?

It is the test for enjoyment 'as of right': not by force (peaceable), not by stealth (open and known to the servient owner), and not by permission. As Bachhaj Nahar v. Nilima Mandal (2008) 17 SCC 491 held, permissive user amounts only to a licence and can never ripen into a prescriptive easement.

Why is a prescriptive right called an 'inchoate' right until a decree is passed?

Because Section 15 requires the qualifying period to end within two years before the contesting suit, completing twenty years of user alone does not finally perfect the right. As observed in Sultan Ahmad v. Valiullah (1912) 10 ALJ 227, the right remains inchoate until established by the decree of a competent court within the statutory window.

Which rights cannot be acquired by prescription?

Section 17 bars four: a right tending to the total destruction of the servient subject; a right to free passage of light or air to an open space of ground (as opposed to a building); a right to surface-water not flowing in a stream or collected in a pool or tank; and a right to underground water not passing in a defined channel.

How much light is protected by a prescriptive right to light and air?

Not all the light previously enjoyed. Following Colls v. Home and Colonial Stores Ltd [1904] AC 179, the dominant owner is entitled only to light sufficient for the ordinary, comfortable and beneficial use of the premises according to the ordinary notions of mankind. An obstruction is actionable only if it amounts to a nuisance by substantially depriving the premises of light.

How does Section 16 affect the twenty-year computation?

Section 16 protects the reversioner. If the servient land was held during the prescriptive period under a life interest or a term exceeding three years, that time is excluded from the twenty years, provided the person entitled on its determination resists the claim within three years after the interest ends. This can defeat a claim that otherwise shows more than twenty years' enjoyment.
