Horizontal privity and vertical privity are two different links a court checks before letting a land-use promise bind or benefit someone who wasn’t in the original deal. Horizontal privity is the connection between the two original parties at the moment they made the covenant. Vertical privity is the connection between one of those original parties and whoever later takes their property. The distinction matters because the traditional rule requires both before you can sue a successor for money damages, and losing either one can leave you with an injunction at best or nothing at all.
Horizontal Privity: The Link Between the Original Parties
Horizontal privity exists at a single moment: when the covenant is created. It asks whether the two people making the promise share some independent property relationship beyond the promise itself. Three forms have developed over time, each broader than the last.1Mississippi Law Journal. A Defense of Horizontal Privity in American Property Law
The oldest form, tenurial privity, required a landlord-tenant relationship between the parties. English common law recognized nothing else. Mutual privity came next, covering parties who hold an easement over each other’s land or share a simultaneous interest in the same parcel, like neighbors with a mutual driveway easement. The most common modern form is instantaneous privity, created when the covenant is written into a deed at the moment the land actually transfers. A seller who puts a residential-use restriction into the deed at closing satisfies horizontal privity automatically, because the promise and the transfer happen in the same instant.
Instantaneous privity is why most enforceable covenants originate in deeds of sale rather than in freestanding agreements between people who already own their lots. Two neighbors who sign a covenant between themselves, without a land transfer or a shared easement, do not have horizontal privity. The promise may still be enforceable, but the toolkit shrinks.
Vertical Privity: The Link Down the Chain of Ownership
Vertical privity looks forward in time. It describes the relationship between one of the original covenant parties and whoever later acquires that party’s interest in the land.2Legal Information Institute. Vertical Privity When the original buyer later sells to a new owner, vertical privity is what connects that new owner back to the promises the buyer made.
Courts recognize two versions, and the difference has practical bite:
- Strict vertical privity requires that the successor receive the predecessor’s entire ownership interest, with nothing held back. A standard sale satisfies this. A lease does not, because the landlord keeps a reversionary interest.
- Relaxed vertical privity is satisfied by any possessory relationship. A tenant leasing from the original covenantor qualifies, even though the landlord retained part of the estate.
The landlord-tenant example is where the split shows up most often. Under a strict rule, a tenant occupying the burdened property isn’t in vertical privity with the landlord for covenant purposes. If the tenant violates the covenant, the benefited neighbor may have no way to reach the tenant directly at law.
Why the Difference Matters: Burden vs. Benefit
This is where privity analysis pays off in real dollars. The requirements for a covenant’s burden to run with the land are stricter than the requirements for its benefit to run.
For the burden to run at law, meaning the obligation follows the land onto a new owner, traditional doctrine requires writing, intent, notice, touch and concern, horizontal privity, and vertical privity.3Harvard Law Review. Touch and Concern, the Restatement (Third) of Property: Servitudes, and a Proposal All six. On the burden side, courts also lean toward strict vertical privity, which is what lets a tenant sometimes escape the obligation entirely.
For the benefit to run, meaning a new owner can enforce a promise made in favor of the property, the list is shorter. Courts generally require writing, intent, touch and concern, and vertical privity, but not horizontal privity, and relaxed vertical privity is enough.3Harvard Law Review. Touch and Concern, the Restatement (Third) of Property: Servitudes, and a Proposal
The reasoning behind the asymmetry is that binding a new owner to somebody else’s obligations affects their property value and autonomy, so every safeguard has to be in place. Letting someone step into an existing benefit is far less intrusive, so the doctrine is more forgiving.
A Worked Example
Picture a seller who deeds a lot to a buyer, and the deed includes a restriction limiting the property to residential use. Horizontal privity locks in at the moment of that sale, because the covenant was created in the same instrument that transferred the land. A few years later the buyer sells to a new owner. Vertical privity now connects the new owner back to the original buyer.
If the new owner opens a commercial business on the lot, the original seller can sue for damages: horizontal privity between the original parties, vertical privity between the buyer and the successor, both intact. The burden ran with the land.
Change one fact. Say the original promise wasn’t in a deed but in a written agreement between two neighbors who already owned their lots. No transfer, no shared easement. Horizontal privity is missing. Even with a perfect vertical chain, a court applying traditional rules won’t enforce this as a real covenant at law, and the benefited party can’t recover damages from the successor.
When Privity Is Missing: The Equitable Servitude Fallback
The doctrine of equitable servitudes developed to close exactly this gap. When a covenant can’t satisfy horizontal privity (and sometimes vertical privity), it may still be enforced in equity, but the remedy shifts from money damages to an injunction.3Harvard Law Review. Touch and Concern, the Restatement (Third) of Property: Servitudes, and a Proposal
An equitable servitude needs only three elements: the original parties intended the restriction to bind successors, the promise touches and concerns the land, and the successor had notice of the restriction. No horizontal privity, no vertical privity. A court can order the violating owner to stop, but it won’t award damages for the period before the lawsuit.
That remedy difference is not academic. If a neighbor’s successor has been running a noisy commercial operation in a residential-only zone for two years, an injunction ends the activity going forward, but only damages compensate for diminished property value and lost enjoyment already suffered. Losing the damages remedy means eating those losses.
Equitable servitudes are the practical workhorse behind subdivision restrictions and homeowners association covenants. When a developer records a declaration before selling individual lots, later buyers get constructive notice through the public record, and courts enforce the restrictions as equitable servitudes even when the technical privity between the developer and the fifth or sixth owner in the chain gets thin.
Is Horizontal Privity Still Required in Your State?
The Restatement (Third) of Property: Servitudes says horizontal privity “is no longer required to create a servitude obligation” and pushes for abolishing the requirement altogether.1Mississippi Law Journal. A Defense of Horizontal Privity in American Property Law Academic consensus mostly agrees.
Case law is another matter. A significant number of states, including Arizona, Connecticut, Iowa, Kentucky, Montana, Nebraska, New Hampshire, North Carolina, Oregon, South Carolina, Texas, Vermont, Virginia, Washington, Wisconsin, and Wyoming, continue to require horizontal privity for the burden of a real covenant to run.1Mississippi Law Journal. A Defense of Horizontal Privity in American Property Law Post-2000 decisions have largely held the traditional line rather than adopting the Restatement.
So the practical advice hasn’t really changed. Don’t assume horizontal privity has been abolished where you are. In states that still require it, putting the covenant inside a deed of transfer, or establishing a shared easement before creating the promise, is what preserves the option of collecting damages later.
A Note on Notice
Privity is only one piece of the puzzle. Even a covenant with perfect horizontal and vertical privity won’t bind a successor who had no way of knowing about it, and a successor who plainly knew about a restriction may still take the property free of it if the privity chain is broken (at least for damages claims). Recording the covenant in the chain of title is what most reliably keeps both problems from sinking enforcement down the road.
Side-by-Side Summary
- Horizontal privity exists at the moment of creation, between the original parties, and requires an independent property relationship (a transfer, a shared easement, or a landlord-tenant arrangement) beyond the covenant itself.
- Vertical privity develops later, between an original party and whoever takes their interest. Strict vertical privity requires transfer of the entire estate; relaxed vertical privity accepts any possessory relationship.
- Burden running at law: both horizontal and vertical privity traditionally required, and vertical privity is usually strict.
- Benefit running at law: only vertical privity required, and relaxed is enough.
- Equitable servitude: neither form of privity required, but the remedy is limited to an injunction.
Getting this analysis right before drafting a covenant, or before relying on one somebody else drafted, is what separates a restriction that follows the land through generations of owners from one that dies at the first resale.
