Definition
The party who grants a lease — that is, the one who conveys a possessory interest in property to another for a defined term or at will, in exchange for rent or other consideration. The lessor retains the underlying ownership or superior interest in the property while surrendering possession to the lessee for the duration of the lease. In the landlord-tenant context, the lessor is the landlord. In commercial and personal property contexts, the lessor may be a financial institution, equipment company, or any entity conveying temporary use rights.

Common Language
Modern common usage (Wiktionary): The owner of property that is leased; the landlord to a lease.
Historical common usage (Webster's 1913): One who leases; the person who lets to farm, or gives a lease.
The common and legal meanings align closely, but the legal term carries more precision than everyday usage suggests. Colloquially, "lessor" implies ownership; legally, the lessor need only hold a sufficient interest to grant the lease — a lessee can become a lessor by subletting, without ever holding title to the property. Researchers should not assume that identifying the lessor settles the question of who holds fee simple ownership.

Common Confusion
LESSOR vs. LESSEE: These terms are mirror images and are occasionally transposed in older documents and transcribed records. The lessor grants; the lessee receives. When reading historical instruments, verify direction of conveyance rather than relying on the label alone, as scribal or typographical error is not uncommon in older deed and lease records.
LESSOR vs. LANDLORD: In residential and agricultural contexts the terms are functionally synonymous, but "lessor" is the broader category. A landlord is always a lessor; a lessor is not always a landlord. Equipment lessors, vehicle lessors, and commercial lessors of personal property are not landlords in any legal sense, and landlord-tenant statutes do not govern them.

Why It Matters in Research
The term is stable across centuries — it has meant the same thing since at least Littleton — but its legal consequences have expanded dramatically. Pre-twentieth-century law imposed minimal duties on lessors: the doctrine of caveat lessee placed responsibility for property condition on the tenant, and lessors enjoyed broad immunity from tort liability for injuries occurring on leased premises. Modern law has substantially eroded that immunity through statutory warranty of habitability requirements, implied covenant doctrines, and premises liability tort rules. Researchers moving between historical and contemporary sources will find the same word carrying very different liability implications depending on the period.
In ejectment actions before the procedural reforms of the nineteenth century, the lessor occupied a distinctive procedural role. The real claimant prosecuted under the fiction of a nominal plaintiff (John Doe) as lessee, making the lessor of the plaintiff the actual party in interest — present in the record but obscured by the fictitious framing. Researchers reading pre-reform ejectment records must understand this device to identify who actually held and contested the land.
In commercial contexts, modern Article 2A of the Uniform Commercial Code governs leases of goods and uses "lessor" in a technical sense that differs from real property usage. A researcher encountering "lessor" in a personal property or equipment finance context should confirm whether real property law or UCC Article 2A governs before applying landlord-tenant doctrine.
Cross-reference to premises liability is essential: the Law Mind Torts & Personal Injury Encyclopedia entry on this topic traces the evolution from lessor immunity to modern duty rules, which is the area where historical and contemporary doctrine diverge most sharply.

Historical Dictionary Support
All four source dictionaries agree on the core definition without meaningful variation. Black's (1st Ed.) gives the shortest formulation: "He who grants a lease." Burrill adds the scope of estates covered — life, years, or at will — tracking Littleton's foundational treatment. Bouvier cross-references lease and landlord-tenant without elaborating, reflecting the term's settled character by the time of his writing.
Black's 2nd Ed. contributes the most historically useful material by explaining the lessor of the plaintiff in ejectment — a procedural concept that the other dictionaries omit entirely. This entry is the most important for researchers working with pre-reform common law ejectment records.
None of the historical dictionaries address the lessor's tort liability, which was largely a non-issue under the immunity regime that prevailed when these works were compiled. The silence is informative: researchers should not read the absence of duty-of-care discussion as confirmation that no duties existed historically; rather, the common law affirmatively denied most such duties, a posture these dictionaries took for granted.

Jurisdictional Note
Statutory modifications to lessor duties — particularly implied warranty of habitability and anti-retaliation protections — vary significantly by state and do not exist in uniform form at the federal level. Researchers working with residential leases should confirm the applicable state statutory scheme, as some jurisdictions extend implied warranty protections broadly while others retain more of the common law framework.
